Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 4 As shown, the hydraulically controlled swing-open check valve of the present invention mainly includes a valve core 1 , a valve body 2 , a first end cap 3 , a second end cap 4 , a torsion spring 6 and an adjusting nut 5 . The first end cover 3 is fixedly connected to one end of the valve body 2, the first end cover 3 and the valve body 2 are sealed by a sealing ring, and a clearance fit is formed between the first end cover 3 and the inner wall of the valve body 2, the second The second end cover 4 is fixedly connected with the other end of the valve body 2, and the second end cover 4 and the valve body 2 are sealed and connected by a sealing ring, and a clearance fit is formed between the second end cover 4 and the inner wall of the valve body 2 . The outer wall of the valve core 1 is provided with a first stopper...

Abstract

The invention discloses a hydraulic control unscrewed one-way valve which comprises a valve core, a valve body, a first end cover, a second end cover, a torsion spring and an adjusting nut, wherein a first check block and a second check block are arranged on the outer wall of the valve core at intervals along the circumferential direction; a third check block is arranged on the valve body; a fourth check block is arranged on the second end cover or the inner wall of the valve body; an oil opening P1, an oil opening P2, an oil opening K, an oil opening T1 and an oil opening T2 are formed in the valve body; the adjusting nut is connected with the valve core through the torsion spring; the valve core can be pushed by oil from the oil opening P1 to rotate, so that the oil opening P1 is communicated with the oil opening P2; the valve core cannot rotate through the pushing of oil from the oil opening P2 to rotate. The hydraulic control unscrewed one-way valve disclosed by the invention has the benefits that under the condition that the oil is not controlled, the oil entering the oil opening P1 can flow to the oil opening P2 and the oil entering the oil opening P2 cannot flow to the oil opening P1; under the condition that the oil is controlled, the oil can flow in two ways, so that one-way flowing or two-way flowing of the oil can be controlled.

Description

technical field [0001] The invention relates to a hydraulically controlled unscrewable one-way valve. Background technique [0002] The hydraulic check valve is a common component in the hydraulic system. The ordinary check valve controls the forward conduction of the oil circuit and the reverse cutoff. On the basis of the ordinary check valve, the hydraulic control check valve adds a control oil port. Under the action of the control oil, the one-way valve can be bidirectionally conducted. And now common one-way valve spools all slide, and there are few check valves with spool rotation. Contents of the invention [0003] The object of the present invention is to provide a hydraulically controlled unscrewable check valve, which can control the one-way conduction or two-way conduction of the hydraulic system by controlling the rotational movement of the valve core. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: t...
