Problems solved by technology

[0002] The rectifier valve refers to the hydraulic valve installed directly in the hydraulic system. Compared with the traditional hydraulic valve, the rectifier valve is directly installed in the hydraulic system through bolts without connecting through oil pipes, which enhances the overall compactness of the system and facilitates daily maintenance. Inspection and maintenance, but the check valve in the rectifier valve of the prior art is directly fixed in the rectifier valve, so when the check valve wears or leaks, it is easy to cause hydraulic oil leakage in the rectifier valve, and the sealing performance is poor , but also reduces the service life of the rectifier valve

Embodiment Construction

[0030] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0031] Such as Figure 1 to Figure 7 As shown, the bridge-type rectifier valve includes a base body 100, and an oil inlet pipe 130 and an oil outlet pipe 140 are arranged through the base body 100 on the base body 100, and a first control valve communicating with the oil inlet pipe 130 and the oil outlet pipe 140 is also arranged on the base body 100. The oil pipe 110 and the second control oil pipe 120, and at least two check valves are respectively arranged on the first control oil pipe 110 and the second control oil pipe 120, and the check valve can make the hydraulic oil introduced by the first control oil pipe 110 pass through the first control oil pipe 110 and the second control oil pipe 120. The second control oil p...

Abstract

The invention provides a bridge type rectifying valve and belongs to the technical field of control valves. The bridge type rectifying valve solves the problem that an existing rectifying valve is poor in seal performance. The bridge type rectifying valve comprises a base body, a first control oil tube, a second control oil tube and one-way valves, wherein the base body is provided with an oil inlet tube and an oil outlet tube which penetrate through the base body, the first control oil tube is arranged on the base body and communicates with the oil inlet tube and the oil outlet tube, the second control oil tube is arranged on the base body and communicates with the oil inlet tube and the oil outlet tube, the one-way valves are arranged on the first control oil tube and the second control oil tube in an inserted manner correspondingly, and the one-way valves enable the hydraulic oil which is led in through the first control oil tube to be led out through the second control oil tube and the oil outlet tube and enable the hydraulic oil which is led in through the oil inlet tube to be led out through the second control oil tube. The bridge type rectifying valve has the advantages of being good in seal performance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of control valves and relates to a bridge rectifier valve. Background technique [0002] The rectifier valve refers to the hydraulic valve installed directly in the hydraulic system. Compared with the traditional hydraulic valve, the rectifier valve is directly installed in the hydraulic system through bolts without connecting through oil pipes, which enhances the overall compactness of the system and facilitates daily maintenance. Inspection and maintenance, but the check valve in the rectifier valve of the prior art is directly fixed in the rectifier valve, so when the check valve wears or leaks, it is easy to cause hydraulic oil leakage in the rectifier valve, and the sealing performance is poor , It also reduces the service life of the rectifier valve. [0003] To sum up, in order to solve the structural shortcomings of existing rectifier valves, it is necessary to design a bridge rectifier valve with g...
