Information
Installation of water control valve
When installed horizontally, the valve cover should be upward. There should be drainage facilities behind the pressure reducing valve of the fire water supply system. When the automatic sprinkler system needs to be pressure-reduced, the pressure-reducing valve should be set in front of the alarm valve (along the direction of the water flow). The pressure-reducing valve provided with a single alarm valve may not be equipped with a pressure-reducing valve; it is matched with multiple alarm valves The pressure reducing valve set should be the pressure reducing valve used by the equipment factory. The pressure reducing valve used in the hot water supply project shall adopt the hot water type pressure reducing valve.
Hot water supply mode of water conservancy control valve
For hot water supply projects using dry pipe circulation (semi-circulation), the pressure reducing valve setting requirements should be the same as for cold water projects; for hot water supply projects using standpipe circulation (full circulation), the pressure reducing valve setting should be To prevent the destruction of the hot water circulation, the pressure of the return pipes in each zone should be balanced at the confluence point.
The hydraulic control valve is a valve for water pressure control. The hydraulic control valve consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose of use, function and location, it can be evolved into 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, etc.
A filter should be installed before the hydraulic control valve, and it should be easy to drain.
The hydraulic control valve is a self-lubricating valve body that uses water and does not require additional lubrication. If the parts in the main valve are damaged, please disassemble it according to the following instructions. (Note: The general consumable damage products in the inner valve are diaphragm and ...
However, there are still some misunderstandings in the application of hydraulic control valves in engineering, such as valve application conditions, valve design and selection requirements, installation points, etc. For this reason, this article intends to use the CECS standard "Hydraulic Control Valve Application Design Regulations" (submitted for review Draft) as the basis, combined with my own experience to explain the {TodayHot} issues in the above-mentioned aspects.
