A flow valve for hydraulic cylinder with convenient hydraulic control ratio

Abstract

The invention discloses a flow valve for a hydraulic oil cylinder with convenient hydraulic control ratio, which comprises a valve body, a threaded rod, a fixing frame and a second bottom plate, the threaded rod runs through the sleeve and the first through hole, and the bottom of the valve body The second through hole is opened on the fixed frame and the upper side of the first bottom plate is fixed with the filter frame by the third bolt, and the first rotating plate, the second rotating plate and the third rotating plate are arranged on the right side of the fixed frame. Rotating plate, the upper and lower sides of the second rotating plate are provided with fixed plates, the rear side of the first rotating plate, the rear side of the second rotating plate and the rear side of the third rotating plate are all fixed with a rotating rod , the slider is arranged on the front side of the compression spring, and the safety turntable is fixed on the rear side of the slider. The hydraulic cylinder with convenient hydraulic control ratio uses a flow valve to pull backward and then turn the safety turntable until the first rotating plate, the second rotating plate or the third rotating plate rotates from the vertical state to the horizontal state. At this time, the material passes through the second The flow of the first rotating plate, the second rotating plate or the third rotating plate is used to complete the hydraulic control ratio.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a flow valve for hydraulic cylinders with convenient hydraulic control ratio. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable. Therefore It is widely used in various mechanical hydraulic systems, and the hydraulic cylinder needs to use a flow valve to control the oil volume when the oil is discharged. [0003] During the flow of the material in the existing flow valve, impurities doped in the material will affect the quality of the material, and the material can only flow in one proportion, and the poor sealing performance will affect the blocking ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a flow valve for a hydraulic cylinder with a convenient hydraulic control ratio, so as to solve the problem that in the flow process of the material in the existing flow valve proposed in the above-mentioned background technology, the impurity doped in the material will affect the flow rate of the material. The quality of the material, and the material can only flow in one ratio, and the poor sealing performance of the interception will affect the interception effect
