Supply Hebei Huafei locking gate valve

Introduction to locking gate valve
The locking valve provided by Hebei Huafei Valve Manufacturing Co., Ltd. is the design and manufacturing technology of valves in heating and water supply pipeline systems. It consists of a valve body, a valve core, a valve stem and a locking mechanism. The locking mechanism is a valve stem connected to the valve core installed in the locking hole of the valve body. The valve stem is equipped with a spring, a pawl and a ratchet lock cap. The valve body It is a three-way, and the first port is a bypass cap. The valve core also has three through holes corresponding to the valve body. After adjusting the position of the valve core, screw on the ratchet lock cap, and the user cannot open it by himself. With reversing and locking functions, the heating and water supply systems can be controlled on and off for one household and a group, but cannot be opened non-destructively, achieving effective control.

Performance advantages of locking gate valve
Small fluid resistance
The sealing surface is affected by the medium Brushing and erosion
Small switch saves effort
The overall rubber coating has good elastic memory
The flow direction of the medium is not restricted
No flow disturbance, no pressure reduction
Adopts the same design as the water pipe machine The flat bottom design is not easy to cause debris accumulation and allows the fluid to flow smoothly
Lightweight and the body is made of high-grade ductile black cast iron
The valve body is precision cast to ensure the sealing of the valve
Simple shape
Short structural length, good manufacturing process, and wide application range.
Installation and maintenance of locking gate valve
The handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
Double gate gate valve should be installed vertically (that is, the valve stem is in a vertical position
The handwheel is at the top)
.
The gate valve with a bypass valve should open the bypass valve before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force)
.
Gate valves with transmission mechanisms should be installed according to the product instruction manual.
If the valve is frequently used on and off
lubricate it at least once a month
