Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, and more specifically, to a hydraulic valve body which is easy to install. 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 divided into direct-acting and pilot-operated types, with pilot-operated types being the most common.

[0003] The existing hydraulic valve body and the control seat are usually fixed by bolts, and the installation space for installing the valve body is sometimes very limited, making disassembly and assembly inconvenient and having low practicality.

[0004] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a hydraulic valve body that is easy to install. By setting a limiting structure in the cross bar, it is connected to the docking block. During the connection process, no external tools are required, making the installation of the valve body more convenient and quick.

[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a hydraulic valve body that is easy to install, comprising a base and a valve body installed on the base, a plurality of cross bars of a connecting head being fixed on the outer wall of the valve body, a groove being provided in the cross bar, a moving rod slidably connected thereto being provided in the groove, an end of the moving rod close to the notch of the groove being rotatably connected with two symmetrically distributed rotating blocks, the rotating blocks being rotatably connected to the inner wall of the groove, a plurality of docking blocks corresponding to the moving rod being fixedly connected to the base, when the valve body is installed on the base, the docking blocks correspond to the position of the moving rod, a slot for inserting the end of the rotating block away from the moving rod being provided on the docking block, a card block being fixedly connected to the end of the rotating block inserted into the slot, and a contact block for abutting against the card block being fixedly connected at the notch of the slot.

[0007] By adopting the above technical solution, when the valve body needs to be installed, the valve body is placed on the base. At this time, the docking block corresponds to the position of the cross bar. The valve body is moved to make the cross bar and the docking block fit each other, so that the groove and the slot will fit each other and be connected. The end of the rotating block away from the moving rod and the card block will be inserted into the slot, and then the moving rod is driven to move so that the moving rod approaches the slot. After the moving rod moves, it can drive the rotating block and the end thereof that is rotatably connected to approach the slot. Since the rotating rod is arranged in a triangular shape and one end is rotatably connected to the inner wall of the groove, after one end of the rotating block moves, it can drive the rotating The block rotates with the rotating connection with the groove as the center of the circle until the end of the rotating block away from the moving block drives the card block to be buckled on the resistance block, thereby realizing the abutment between the card block and the resistance block. In this way, the cross bar can no longer be pulled out, the cross bar can be connected with the docking block, and the valve body can be installed on the base. When the valve body needs to be removed, the moving rod is driven away from the slot, and the moving rod can drive the rotating block to rotate in the opposite direction, and the rotating block can drive the card block to rotate away from the resistance block, and the card block is pulled out of the slot, and the cross bar is separated from the docking block. The entire disassembly and assembly process does not require the aid of external wrenches or other tools, making the disassembly and assembly of the valve body more convenient.

During the rotation of the driving rod, the driving rod can move along the through hole, and the movement of the driving rod can drive the movable seat to move, so that the position of the valve body in the horizontal direction can be adjusted to meet the use requirements in more situations. There is no need to frequently disassemble and assemble the valve body, and it is more convenient to use.

[0014] The utility model is further configured as follows: a limiting block is fixedly connected to the side wall of the movable seat, and a limiting groove for inserting and moving the limiting block is arranged on the inner wall of the accommodating groove.

[0015] By adopting the above technical solution, when the movable seat moves along the inner wall of the accommodating groove, the limiting block will be inserted into the limiting groove and move, so that the movable seat is more stable during the movement.

[0016] The utility model is further configured as follows: one end of the driving rod extending out of the through hole is fixedly connected with a second knob.
