Working Principle Of Hydraulic Valve

Ningbo E.H Hydraulic Co.,Ltd | Updated: Oct 20, 2017



The basic structure of the hydraulic valve mainly includes the valve core, the valve body and the driving valve core in the valve body to do the relative movement control device. The main form of the spool is the slide valve, the cone valve and the ball valve, and the valve body is apart from the valve body hole or seat hole which is matched with the valve core. There is also the inlet and outlet of the external tubing and the outlet; the device that drives the valve core in the valve body can be a hand-adjustable mechanism, or a spring or electromagnet, Hydraulic Valves and some occasions are driven by liquid pressure. In the working principle, the hydraulic valve is using the valve core in the valve body relative movement to control the valve mouth of the on-off and opening size, in order to achieve pressure, flow and direction control. Hydraulic valve work, the valve size of all valves, valve inlet, Hydraulic Valves the pressure difference between the outlet and the flow through the valve of the relationship between the orifice flow formula (Q=KA·ΔPM), only a variety of valve control parameters are different.

Currently used hydraulic valves because of its variety of product models, therefore, the use of hydraulic valves which also with the hydraulic valve to improve the attention, after the 60 's, the development of the hydraulic valve has made a very significant progress, according to different occasions the hydraulic valve may have different functional value, then what are the main uses of the hydraulic valve?

Hydraulic valve is a kind of pressure oil operation automation element, it is controlled by the pressure valve, usually with the solenoid valve combination, can be used for long-distance control of hydropower station oil, gas, water pipe system of the break. Often used for clamping, control, Hydraulic Valves lubrication and other oil circuits. There are direct type and pilot type of the division, more use of pilot. Hydraulic valve is used to control the flow direction of oil in the hydraulic system or adjust its pressure and flow, so it can be divided into directional valve, pressure valve and flow valve three categories. A valve of the same shape can have different functions because of the different mechanism of action. Pressure valves and flow valves control the pressure and flow of the system using the throttling effect of the flow cross-section, while the directional valve controls the flow direction of the fluid by using the replacement of the channel. That is to say, although there are a variety of different types of hydraulic valves, Hydraulic Valves they still maintain some of the basic points of common.

Hydraulic valve is used to reduce and stabilize the system of a branch of the oil pressure, often used for clamping, control, lubrication and other circuit. It has the direct type, the forerunner type, the superposition type cent.

A component used in hydraulic fluid to control the flow and direction of a liquid pressure ﹑. The control pressure is called the pressure control valve, the control flow is called the flow control valve, the control ﹑ breaks and the flow direction is called the directional control valve.

For products and equipment, their primary use is the meaning of their existence, from the point of view of the hydraulic valve, its simple structure, easy to install, simple maintenance, Hydraulic Valves the use of security and so on, are the main reasons for users to love and support it, I believe that the future of the major use of hydraulic valves for the development of hydraulic valves is the premise of better.
