Comparison and analysis of hydraulic control valve and other valves Hydraulic control valve brings convenience for daily water use
Hydraulic control valve variety, complete functions, superior performance, debugging without manual operation, without electricity, gas and other power sources, no complex actuators, simple maintenance, convenient, can be installed both horizontally and vertically. Let’s talk about the principle of diaphragm hydraulic control valve characteristics, as well as comparison and analysis with other valves.
Diaphragm hydraulic control valve series of various types of valves are by the main valve, pilot valve, control pipeline or electrical components. The main valve structure is exactly the same, but because of the configuration of the pilot valve and control pipeline direction is different, and derived from different functions and uses of hydraulic control valve.
Diaphragm type hydraulic control valve main valve working principle
The diaphragm divides the main valve into upper and lower cavities. During the use of the main valve, the upper and lower cavities of the diaphragm are filled with pressure medium. With the pilot valve outside the main valve to control the pressure difference between the upper chamber and the lower chamber, so as to control the diaphragm up and down movement or stop at a certain position, also realize the main valve open and close and adjust the purpose.
Diaphragm type hydraulic control valve features are as follows:
● Diaphragm type hydraulic control valve adopts all-flow linear design, small fluid resistance, large flow, strong resistance to cavitation;
● The sealing ring adopts the international advanced star sealing ring structure, does not fall off, does not warp, elastic seal. Guided by a low friction, positioned stem for reliable seal performance and longer life;
● Detachable stainless steel 304 seat, corrosion resistance, erosion resistance, good sealing performance;
● The valve body is made of high precision ductile iron and sprayed with non-toxic epoxy resin.
● The diaphragm is made of nylon reinforced rubber, three-dimensional mesh, good elasticity, high pressure resistance, long service life;
● Series of products using stainless steel pipe, corrosion resistance, higher strength.
Diaphragm type hydraulic control valve and other valves comparison:
● Diaphragm hydraulic control valve for reduced diameter products, fluid resistance, small flow, valve cavitation is serious; Seat bore 60~80%
● Using O-ring or square pad structure, easy to fall off, warped, the need for greater sealing force;
● No valve seat body seal, it is easy to be corroded, washed, unable to seal;
● The diaphragm is thick and hard, inelastic, low pressure resistance, must be replaced frequently;
● Diaphragm hydraulic control valve products using copper pipe, low strength, easy to break. Easy to lose, long time after the use of the outer surface will be oxidized black.
Water control valve brings convenience for daily water use
With the modernization of industry, machinery manufacturing has made great progress. As a remarkable achievement in mechanical manufacturing, water control valves have won the favor of factories and enterprises. Control valve is essentially a management tool, mainly used in water conservancy project management and water supply pipeline management, control valve types, and daily life in a wide range of applications.
The control valve can not only be used in large hydraulic engineering, but also in the daily water management of residents. The operator may use valves to cut off or release the flow of water. If water is needed, it can be released. If water is not needed, the flow can be cut off to help the user. Save water and avoid wasting it.
Water control valves can also regulate the flow of water and help users save water. Now people’s life forms have changed a lot, people are more and more demanding on water, all uses need water pipe. Once this is done, valves need to be controlled to distribute water to meet the needs of different functions.
