Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a horizontal check valve for a hydraulic system. Background Technique

[0002] A hydraulic system is a device for transmitting pressure, usually composed of a power element (such as a hydraulic pump), an actuator (such as a hydraulic cylinder or a hydraulic motor), a control element (such as various valves), auxiliary elements (such as a fuel tank, a filter, a pipeline, etc.), and hydraulic oil, etc.; a horizontal check valve is a valve used to achieve one-way flow, which can prevent the medium from flowing back and ensure the correct flow direction of the fluid. The horizontal check valve has a wide range of applications in the hydraulic system.

[0003] The horizontal check valve usually consists of components such as a pipeline flange, a valve body, a spring, a sealing ring, etc. Among them, the valve body is one of the most important components. During the use of the horizontal check valve, in order to ensure the installation stability of the horizontal check valve, the horizontal check valve is fixed to a fixed platform by bolts; usually, multiple bolts are used to install and fix the horizontal check valve and the fixed platform. However, although this installation method has the advantage of firm installation, when disassembling, tools such as wrenches are needed to gradually remove the bolts, resulting in laborious disassembly of the horizontal check valve and low efficiency. During the use of the hydraulic system, the disassembly, assembly and maintenance of the horizontal check valve are essential. In view of this, we propose a horizontal check valve for a hydraulic system. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related technologies to a certain extent. For this reason, an object of the utility model is to propose a horizontal check valve for a hydraulic system. By pushing the chuck into the sliding cavity, the disassembly of the valve body can be realized. This design improves the convenience and efficiency of the disassembly and assembly of the valve body, and is conducive to the maintenance of the horizontal check valve of the hydraulic system.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A horizontal check valve for a hydraulic system includes a valve body. An interface is opened at the bottom of the valve body. Installation plates are fixed to the bottom ends of both side walls of the valve body, and fixing grooves are opened at the tops of the installation plates.

[0007] An installation part is provided below the valve body. The installation part includes a bottom plate. Fixed seats are fixed on both sides of the top of the bottom plate, and the fixed seats pass through the fixed slots. Two sliding chambers are formed inside the fixed seats, and connecting slots communicating with the sliding chambers are formed above the front and rear walls of the fixed seats. A guide rod is fixed between the two sliding chambers, and springs are sleeved at both ends of the guide rod. Sliders are arranged in the sliding chambers, the guide rod passes through the sliders and is slidably connected with the sliders, and one end of the spring abuts against the slider. On the upper parts of the two opposite end faces of the two sliders, clamping heads are fixed, and the clamping heads pass through the connecting slots and protrude above the installation plate.

[0008] In addition, the horizontal one-way valve of the hydraulic system proposed according to the above application may also have the following additional technical features:

[0009] Specifically, a rectangular groove is formed on the top of the bottom plate, and the cross-sectional shape of the rectangular groove is rectangular.

[0010] Specifically, ear plates are fixed on the left and right side walls of the bottom plate, and mounting holes are formed on the ear plates.

[0011] Specifically, the cross-sectional shape of the fixed slot is rectangular, and the size of the fixed slot is adapted to the size of the fixed seat.

[0012] Specifically, the clamping head and the slider are of an integrally formed structure, and the cross-sectional shape of the clamping head is triangular.

[0013] Specifically, the overall shape of the slider is rectangular parallelepiped, and the size of the slider is adapted to the size of the sliding chamber.

[0014] Specifically, the cross-sectional shape of the bottom plate is rectangular, and the bottom plate is fixedly connected with the fixed seat by bolts.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] By providing the installation part: the fixed seats on both sides pass through the fixed slots.

[0028] In this embodiment, a rectangular groove 200 is formed at the top of the bottom plate 20, and the cross-sectional shape of the rectangular groove 200 is rectangular. The arrangement of the rectangular groove 200 facilitates the passage of the pipelines of the hydraulic system and is conducive to the connection of the pipelines with the interfaces 11.

[0029] In this embodiment, ear plates 26 are fixed to both the left and right side walls of the bottom plate 20, and mounting holes 260 are formed in the ear plates 26.
