Embodiment Construction

[0013] Such as figure 1 As shown, the hydraulic system mainly includes pressure reducing valve 1, hydraulic control check valve 2, reversing valve 3, pressure measuring point 4, control cylinder 5, accumulator 6, throttle valve 7 and check valve 8; control cylinder 5 is directly connected to the sliding sleeve, the reversing valve 3 switches the open and closed states of the valve, the combined use of the pressure reducing valve 1 and the hydraulic control check valve 2, the combined use of the accumulator 6 and the throttle valve 7, the above structure The system itself has the characteristics of two-stage pressure adjustment and delayed pressure relief; the throttle valve 7 is adjusted to control the time of the depressurization process; the effect of maintaining high pressure for a period of time is realized through the energy storage of the accumulator.

[0014] Such as figure 2 As shown, when the control valve is open, the valve control cylinder is always in the extende...

Abstract

A ball valve hydraulic circuit, whose action is completed by its control cylinder and a series of control components, mainly including pressure reducing valve, hydraulic control check valve, reversing valve, pressure measuring point, control cylinder, accumulator, throttling Valves and one-way valves, etc., the hydraulic control circuit designed to solve the problem can greatly reduce the high-pressure working conditions of the valve control cylinder, and play a significant role in prolonging the life of the valve and its control mechanism. The control of the external control oil drain port realizes the change of the control pressure of the pressure reducing valve; through the energy storage function of the accumulator, the effect of maintaining high pressure for a period of time after reversing is realized; through the adjustment of the throttle valve, the reduction The time control of the pressure process; in addition, due to the characteristics of the hydraulic system itself, such as secondary pressure adjustment and delayed pressure relief, its practical application range has been increased.

Description

technical field [0001] The invention relates to a hydraulic circuit, which is especially suitable for mining machinery. Background technique [0002] The ball valve came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, it has rapidly developed into a major valve category in just 40 years. In western industrially developed countries, the use of ball valves is increasing year by year. In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has the action of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of med...
