Product Description

intro

The valve makes the system need not set up a special fire separate water supply network, greatly saving the construction cost and water consumption. Valve control sensitivity is high, safe and reliable, easy to debug, long service life. [1]
Hydraulic control valve is water pressure control valve, hydraulic control valve is composed of a main valve and its attached catheter, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose of use, function and different places 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 and so on.
YX741X diaphragm adjustable pressure regulator before the filter should be installed, and should be easy to discharge the requirements.
Water control valve is a use of water self-moistening type valve body, no need to add oil lubrication, if the main valve parts are damaged, please disassemble according to the following instructions. (Note: The general consumption of damaged products in the inner valve is the diaphragm and...
But in the application of hydraulic control valve in the project, there are still some misunderstandings, such as the applicable conditions of the valve, the valve design selection requirements, installation points, etc. Therefore, this paper intends to CECS standard "hydraulic control valve application design regulations" as the basis, combined with my experience to describe the above aspects of the problem.

Design key points

(1) The hydraulic control valve used in engineering is a product that has passed the manufacturer's inspection, has complete various marks and meets the requirements of technical data.
(2) According to the functional requirements, select the type of valve, and then according to the pipeline transmission medium, temperature, building standards and owner requirements, determine the valve body and sealing parts of the material. Commonly used valve body materials are cast iron, copper iron, copper, plastic and so on. The commonly used sealing surface and lining materials are copper alloy, plastic, steel, cemented carbide, rubber and so on. The valve body material should match the pipe material.
(3) The nominal pressure of the valve has different levels such as 0.6, 1.0, 1.6, 2.5 and 4.0MPa, and the working pressure of the pipeline transport medium should be less than the nominal pressure value of the valve.
(4) The hydraulic control valve setting in the project should have enough space for management, operation, installation and maintenance, and should meet the requirements of the pipeline for the valve.
(5) When the pipeline is connected by flanges, the hydraulic control valve connected by flanges should be used; When the pipeline is connected in a groove, the hydraulic control valve connected in a groove should be used.
(6) The hydraulic control valve should be set on the pipeline with one-way flow of the medium.
(7) The arrow direction on the main body of the water control valve must be consistent with the flow direction of the pipeline system.
(8) The pipe section of the hydraulic control valve should not be blocked and blocked. In the highest position of the pipe network and other gas storage section should be set up automatic exhaust valve.
(9) When the valve is installed horizontally, the valve cover and stem should face upward. When installed vertically, the valve cover and stem should face outward.
(10) Strength and tightness test should be done before valve installation.
(11) The strength and tightness test of the valve should comply with the following provisions.
A, the strength test pressure of the valve is 1.5 times the nominal pressure;
B, the tightness test pressure of the valve is 1.5 times the nominal pressure;
C, the test pressure in the test duration should remain unchanged, and the shell packing and valve disc sealing surface no leakage;
D, valve test duration according to the table above.
