Product introduction
[product use]
Z43H/X cast steel flat gate valve used in natural gas, petroleum, chemical industry, environmental protection, urban pipeline, gas pipeline and other pipelines, venting systems and vapor storage device, used as a hoisting equipment. Z43 type single gate plate gate valve with diversion hole is suitable for long distance transportation pipeline of natural gas extraction and purification.
Product features:
1, the valve seat sealing structure should be flexible with preload, the upper and lower reaches of the sealing seat at the same time the structure of the seal. Between the valve seat and the sealing material is always face to face seal.
2, the valve seat has a self cleaning function, and the valve is open or closed in the process of direct erosion of the air. The valve seat shall be made of lubricated and non abrasive materials.
3, the valve actuator failure will not affect the rest of the valve, repair and replacement work can be carried out without removing the valve.
4, yoke sleeve: Aluminum Bronze yoke sleeve configuration needle thrust bearing, reduce operating torque to the maximum extent.
5, stem length of thread until the bracket; pin and spot welding; stability.
Pressure seal: has the advantages of simple structure, configuration sub ring and silver plated low carbon steel washers, aid disassembly and achieve the best bonnet seal.
7, seat ring: welded valve seat ring perpendicular to the flow channel, easy to maintain.
8, the implementation of the agency: these valves can be configured with electric, hydraulic or pneumatic actuator. DN300 the following configuration standard manual hand wheel, DN350 above the configuration of helical gear operating mechanism.
9, yoke: fully assembled yoke through seismic testing, easy maintenance and installation of the implementing agencies.
10, gland: two piece, self-adjusting gland, to avoid being ejected.
11, the whole back seat: hard surface, the longest service life.
12, the valve flap: spring loaded valve can be adjusted to reduce the torque requirements of the actuator.
13, the overall check: the overall casting bracket stop device, positioning and assembly of the bracket valve flap, making the valve seat more stable and reliable.
