Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a high-pressure-resistant hydraulic valve component. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure-regulating valve and is usually used in combination with an electromagnetic pressure-regulating valve. It can be used to remotely control the on / off of oil, gas, and water pipeline systems in hydropower stations. It is often used for clamping, controlling, lubricating, and other oil circuits. It is an element used to control liquid pressure, flow, and direction in hydraulic transmission. The one that controls pressure is called a pressure control valve, the one that controls flow is called a flow control valve, and the one that controls on / off and flow direction is called a directional control valve. Generally, a hydraulic valve is installed at the outlet of the pump to control the flow and pressure of the hydraulic system and protect the pump. However, the entire valve body is exposed to the outside and no necessary protective measures are set. The pressure resistance and protection of the entire valve body are insufficient.

[0003] Regarding the above-mentioned related technologies, the applicant believes that: when the hydraulic valve is installed at the outlet of the pump, the entire valve body is exposed to the outside, and no necessary protective measures are set. The pressure resistance and protection of the entire valve body are insufficient. Therefore, it is necessary to install necessary support and fixing measures to provide pressure resistance and protection for the hydraulic valve.

[0004] To this end, the utility model provides a high-pressure hydraulic valve assembly to solve the above problems. Utility Model Content

[0008] Furthermore, the bottom wall of the support plate fits in with the left side of the top wall of the mounting plate, and bolts are screwed on the four corners of the top wall of the support plate. The bottom ends of the bolts are screwed through the support plate and the top wall of the mounting plate to be screwed together.

[0009] Through the above technical solution, the support plate supports the anti-pressure component and is easy to disassemble and assemble.

[0010] Furthermore, the bottom wall of the valve body is fitted with the top wall of the support plate, and the outer walls of the trapezoidal blocks are slidably connected with the inner walls of the corresponding trapezoidal grooves.

[0011] Through the above technical solution, the trapezoidal block drives the anti-compression frame to move when sliding on the inner wall of the trapezoidal groove.

[0012] Furthermore, the pressure-resistant frame is C-shaped and matches the shape of the outer wall of the valve body, the inner wall of the pressure-resistant frame is in contact with the outer wall of the valve body, and the pressure-resistant frame is symmetrically arranged front to back.

[0020] Beneficial effects

[0021] The utility model provides a high-pressure hydraulic valve assembly. Compared with the existing technology, it has the following advantages:

[0022] (1) The high-pressure hydraulic valve assembly drives the trapezoidal block to slide on the inner wall of the trapezoidal groove and compresses the spring through the pressure-resistant frame, and the valve body is installed on the outlet pipe of the pump body outlet. The spring pushes the trapezoidal block to slide on the inner wall of the trapezoidal groove, and the pressure-resistant frame fits the valve body for protection. The T-shaped block drives the rotating shaft to rotate on the inner wall of the first T-shaped groove. When the T-shaped block enters the inner wall of the second T-shaped groove during rotation, the pressure-resistant frame is closed and limited, so that pressure-resistant protection measures are provided on the outside of the valve body, thereby improving the pressure resistance and protection of the entire valve body and preventing the valve body from being exposed to the outside. In addition, the pressure-resistant assembly is easy to install and disassemble, and it is also easy to open when repairing the valve body later. BRIEF DESCRIPTION OF THE DRAWINGS
