The double flange electric ball valve is widely used in pipeline equipment, and has a certain anti permeability function to prevent water from seeping, flowing and flowing to the lower layer. In the room with water, the casing height in the room with water (kitchen, toilet, etc.) shall be 50mm higher than the survival ground, and the casing of the plastic water supply pipe shall be 100mm higher than the survival ground.
It shall be sealed tightly with ointment. Through analysis, our technicians have summarized two methods to solve the problem of water channel flowing: one is the low height of casing; Second, although the height is enough, the casing opening is not sealed tightly. The solution is very simple. Due to the limitation of conditions, the clear distance from the outdoor water supply pipeline to the septic tank is less than the specification requirements. The water supply pipeline must also be additionally equipped with a casing, and the length shall be in accordance with the design requirements. When restricted by conditions, the indoor water supply pipe must pass under the drainage pipe, the water supply pipe must be equipped with a sleeve whose length should not be less than the design requirements to prevent water pollution.
The double flange electric ball valve is composed of loose flange expansion joint, short pipe flange, valve screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate the installation error of the pipeline. The double flange electric ball valve cannot absorb the axial displacement. Double flange valve connection is mainly used for loose sleeve connection of pump, valve and other accessories. The double flange electric ball valve is composed of loose sleeve expansion joint, short pipe flange, valve screw and other components, which can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is important for loose sleeve connection of pump, valve, pipeline and other accessories.
Summarize the force of Shanghai double flange electric ball valve in water conservancy construction. Water conservancy construction is a huge and lasting project, with high requirements for completion standards. In water conservancy construction, electric ball valve and expansion joint play an important role, and expansion joint has good flexibility and flexibility, Therefore, it is generally acceptable in the environment with high requirements for joints. The electric ball valve has the characteristics of good connectivity, which not only plays the role of connection, but also protects the pipeline when connecting between pipelines. The double flange electric ball valve is mainly used for the connection of pumps, valves and other accessories.
The double flange electric ball valve is composed of expansion joint, short pipe flange, valve screw and other components. It can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is important to connect pumps, valves, pipelines and other accessories. The double flange electric ball valve is composed of main parts such as body, seal ring, gland, telescopic short pipe, etc. This product is suitable for adjusting the installation length of both ends of the product and the flange during installation in pipes connected with flanges on both sides. Tighten the gland bolts diagonally and evenly, and use them to form a whole with a certain displacement to facilitate the adjustment according to the site size during installation and maintenance, During operation, the reverse axial thrust can be transmitted to the whole pipeline
