Ball Valves

Cranes of balloon all-welded with an elongated rod - Shut-off valves intended for underground pipelines. Underground ball valves are made with a conditional passage of the passage (DN) from 15 to 500 with the output of the rod under the carpet and the ability to eliminate the rod from 1,000 to 4,500 mm, calculated for the working pressure (PN) 16 and 25.

The underground method of laying trunk pipelines today is considered one of the most appropriate. However, it requires the use of a special type of locking reinforcement, and the most suitable for these purposes are cranes balls for underground installation with an elongated rod.

These products have small overall dimensions and weight, body design underground ball cranes Excludes any contact of the internal parts of cranes with soil. For underground installation, most often applied All-welded ball valvesallowing you to minimize the leakage of the working medium through the cranes housing. The main type of accession to the pipeline underground cranes with an elongated rod - under the welding, which ensures maximum tightness and durability of the connection.

In order to protect the cranes from the mechanical damage and exposure to the soil, an additional protective coating of the body of the ball cranes is carried out. The coating can be different - Frusis, Biurs.

For the purpose of management underground ball cranes The extension cords of the rod are provided in their designs connecting the ball with the control organ located above the ground surface.

The height of the rod extension can be any at the request of customers. Extension cords are standard length from 1000 to 4500 mm, as well as height adjustable, so-called telescopic rods.

For driving Underground installation cranes Apply pneumatic or pneumohydroprys. Driving control is carried out by the Transported Environment.

Crane ball polyethylene is used in the construction of gas supply and water supply systems. Cranes Ball PNDs can be installed both in the wells / chambers, and there is a variant of the non-measured installation, while the tap for the underground installation is equipped with a telescopic extension, and the extension rod is displayed under the overhead carpet.

As a rule, the ball polyethylene crane produce diameters from 32 mm to 315 mm.

Operating pressure: gas - up to 10 bar., Water - up to 16 bar.

The ball polyethylene crane with the PND tube or electrical fittings, or welding jack, is connected.

The ball valve of the PND we can finish the following fixtures:

• Telescopic crane extension;
• Key for ball valve PND;
• The extender for the key of the ball valve of the PND in the protective casing.

The telescopic extension cable is designed to open or close the ball valve PE.

Design execution of the extension:

• axis that is made of metal;
• protective casing made of polyethylene, to protect the metal part of the crane from corrosion.

The key for the ball valve is made of polyvinyl chloride (PVC) in the form of a hexagon.

Polyethylene crane was originally invented for the construction of gas networks, but today the polyethylene crane is actively used in the construction of water supply networks. Often, polyethylene crane is used as a replacement of familiar valves, as the polyethylene tap is easier and cheaper in the installation than the valve.

On PNP pipelines also use PE faucet collection-collapsible, which joins the PND tubes with a collet clamp, otherwise it is called a compression crane. No need to confuse these products. A compression crane can only be used on plumbing and such cranes are only up to 110 mm in diameter. In this section, we present the Crane PND, which can be used including on gas pipelines. Such a PND Crane withstands the working pressure to 16 atmospheres on the water supply, and the polyethylene gas crane can withstand up to 12 atmospheric pressure.

Today in the infrastructure of each settlement - Small in the population, middle or, on the contrary, is large, functions a huge number of pipelines of various purposes. The use of polymer pipes for the installation of water supply and gas networks significantly simplifies the maintenance of the entire system and its individual sections, and also increases the duration of their service. To regulate the environmental flow and control of the efficiency of the system on underground polymer networks, fittings from the corresponding materials are used - PE ball cranes.

The convenience of using this type of reinforcement is that its installation is made in a susceptible way. To set the ball valve to the network, it is not necessary to equip the well, the crane after installation on the network is enough to fall asleep with soil, removing the control mechanism to the surface. These products are currently produced by many companies, both domestic and foreign, and their application is justified. The use of polyethylene ball valves allows you to quickly solve various technical tasks, providing reliable overlapping of the flow running through the medium pipeline.

The installation of underground pipelines is carried out at different depths, but in the context of the Russian climate for many networks, there is a sufficiently deep running of the pipes - below the waterproof point. Due to the peculiarities of installing networks, the question of simplicity of access to the valve installed on the network arises. Each polyethylene (PND) ball crane should be controlled at any time, regardless of its depth of installation.

For this apply different kinds Control devices, in particular, rods and spindles of fixed and telescopic length, which are displayed on the surface and serve to control pipeline equipment and its preventive maintenance.

In addition to facilitating devices underground strip, spindles and rods extend their service life because they take part of the leading load on the opening-closing mechanism. For the safety of the device and control mechanisms, it is customary to place a ball valve under the carpet. Installing cranes for cutting is applied in cases where the location of the reinforcement is under the roadway or in other hazardous conditions. As a protective agent for underground installation reinforcement, hatches are also used. Unlike the carpet, the hatches are in short with the surface of the soil or road surface.

The use of a polyethylene crane in the underground performance has several advantages in comparison with other types of reinforcement. First of all, the crane of the ball PE (PND) is distinguished by compact sizes and ease of control. Its installation on the network is carried out by butt or electrical welding.

To speed up and facilitate the installation of cranes on the network, cranes are produced with built-in metal mortgage heaters. In the process of welding, they melts polyethylene and combine the reinforcement with pipes. Many manufacturers also equip their products with welding indicators - special marks that simplify the work of welder operators.

Today is the Ball Cranes for Polymer Networks may have various design. Products fully made from polyethylene are in great demand. They differ in strength, durability, full corrosion resistance, and manufacturing material allows them to maintain elasticity that gives resistance to mechanical loads.

Polyethylene shut-off crane with a ball valve has several main elements in the design - body and actually, the shutter-ball. In a spherical gate, there is a hole of a certain diameter, through which the device's open position is fluidally transported by the environment.

Shut-off ball valve can be full and incomplete. The first option is more common: these cranes in such cranes, the diameter of the conditional passage coincides with the diameter of the internal passage of the pipe. Full-pass polyethylene ball valves are more efficient because they do not reduce bandwidth network.

In order to close the crane, you need to rotate the control mechanism - handles, spindle, rod, lever 90 degrees. The shutter turns and overlaps the environment. In order for the design to be completely sealed in a closed state, the ball valve and the control mechanism have seals in the form of traffic jams, gaskets and rings. In addition, in its design, the PE crane can use clamping springs for additional fixation of the shutter.

The use of ball valves on polymer networks is beneficial and convenient. Most of the products are made of polyethylene low pressure Brands PE 100 and PE 80. This is a solid material that is well connected to the polymer pipes during the welding process. In addition, the Polyethylene Underground Crane is favorably different from metal shutters and valves - it's easier to control, and the weight is much smaller.

A small weight is a lot of advantages: simplicity of transportation, ease of installation, insignificant load on the pipeline.

Installing the device on the network plastic pipes Small diameters do not require the use of additional supports and fixations, in contrast to cranes with metal elements in the design.

Polyethylene is resistant to electrochemical corrosion, which is especially relevant for reinforcement on gas pipelines. The material is well resisting corrosion, opposes aggressive soils. Water supply installed on the water supply chain Polyethylene preserves its operational characteristics for a long time.

The average life of the device is from 15 to 25 years, while all the maintenance is in the annual single opening-closing of the shutter.

The internal parts of the device are not subject to the formation of lime deposits and precipitation. Polyethylene shut-off valves can be used in drinking water supply networks, as it corresponds to accepted hygienic and sanitary standards and parameters. The use of balloon polyethylene cranes on most gas and water supply networks allows you to save money on gasket and network arrangement, while maintaining its efficiency and safety of operation.
