Hot water supply method for hydraulic control valve

The hot water supply project using the dry pipe main circulation mode (semi-circulation mode), the pressure relief valve setting requirements should be the same as the cold water project; the hot water supply project using the riser circulation mode (full circulation mode), the pressure relief valve should be set To prevent the destruction of the hot water circulation, the pressure of the return pipes at each junction should be balanced at the meeting point.

The hydraulic control valve is a water pressure control valve. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose, function and location, it can be evolved into a remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve and so on.

Filters should be installed before the hydraulic control valve and should be easy to discharge.

The hydraulic control valve is a self-lubricating valve body that does not require additional oil lubrication. If the components in the main valve are damaged, please follow the instructions below for disassembly. (Note: The damage to the inner valve is generally diaphragm and...

However, when applying hydraulic control valves in engineering, there are still some misunderstandings, such as the applicable conditions of the valve, the design requirements of the valve, the installation points, etc. To this end, this paper intends to use the CECS standard "Design Rules for the Application of Hydraulic Control Valves" (for review) Based on the manuscript, combined with my experience to explain the above aspects.
