Product Description

Principle and function of MZ45X,RVZM extension rod elastic seat sealing gate valve; The gate valve with elastic seat seal (extension rod) adopts the design scheme that the valve stem can be extended without maintenance, and it is buried at one time, so as to avoid the expensive cost of the valve well and the huge investment brought by repeated road reconstruction and valve replacement, beautify the road environment, resist rolling, and avoid safety accidents caused by the loss of the manhole cover. The valve stem can expand and contract freely according to the depth of the valve well. The top of the valve stem of the underground (extension rod) elastic seat sealing gate valve is provided with a valve switch display, and a signal remote transmission device and a valve misoperation locking device can be installed. The elastic seat-sealed gate valve adopts novel structural design, strict manufacturing technology and high-performance new materials, which overcomes the shortcomings of traditional gate valves, such as poor sealing, easy corrosion of internal parts, especially gate plates, elastic fatigue and aging of rubber, reliable sealing performance, brisk operation, simple and convenient maintenance and long service life. It is suitable for domestic water system, water supply and drainage system, sewage treatment system, chemical fluid conveying system, etc. It is used as a cutoff device for fluid pipelines in industries such as construction, urban environmental protection, petrochemical, medicine, food, metallurgy, textile and electric power. Performance characteristics of MZ45X,RVZM extension rod elastic seat sealing gate valve;
1.The adjustable lengthened dowel bar can be lengthened with the landfill depth of the gate valve, so as to make the transmission square head close to the ground and facilitate the opening and closing of the valve;
2.the adjustable extension sealing sleeve protects the extension dowel bar from being squeezed by sediment, which is convenient for rotating the central shaft;
3.In the process of opening and closing the gate valve, the central shaft does not move up and down, which reduces the landfill depth and will not be higher than the ground;
4.The top sealing box has multiple functions of anti-theft and protection; Small floor space; Not afraid of wheel crushing5.Use a special trapezoidal wrench to open and close the gate valve, so as to prevent irrelevant personnel from opening and closing the gate valve at will.
