Description

Technical Field

[0001] The utility model relates to a valve pressure detection tool, in particular to a valve pressure detection tool, belonging to the technical field of valve pressure detection. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. During the production of valves, the valves will be pressure tested to ensure the sealing of the valves.

[0003] A valve pressure detection tool is disclosed in the Chinese patent application publication specification CN216669256U. The device is provided with a pressure detection component, a lifting component and a fixing component. Valves of different diameters can be sealed through a conical block, so that the device is suitable for pressure detection of valves of different models, is simple to operate, and improves efficiency.

[0004] However, during the implementation of the technical solution of the above patent, it is impossible to perform pressure testing on two-way valves and three-way valves of various shapes. The sealing blocks of the existing testing tooling can mostly only move in a single direction, and the angle of the sealing block cannot be adjusted, so that the sealing block cannot block two-way valves and three-way valves whose angles are not 90 degrees or 180 degrees, making the applicability of the testing tooling relatively small. Utility Model Content

[0007] The outer surface of the threaded rod is threadedly connected with an internal thread moving block, the upper surface of the internal thread moving block is fixedly connected with a connecting rod, the top end of the connecting rod is rotatably connected with an anti-slipping slider, and the anti-slipping slider is slidably connected to the inner wall of the L-shaped frame.

[0008] Furthermore, an air pump is fixedly connected to the outer surface of the L-shaped frame, and a connecting hose is fixedly connected to the output end of the air pump. The connecting hose passes through the conical sealing block and is fixedly connected to the conical sealing block. When the conical sealing block blocks the valve, the operation of the air pump can blow air and increase pressure into the valve through the connecting hose.

[0009] Furthermore, a pressure detection sensor is fixedly connected to the outer surface of the conical blocking block, and the pressure detection sensor can detect the air pressure in the valve.

[0010] Furthermore, the outer surface of the threaded rod is rotatably connected to two support seats, and the two support seats are fixedly connected to the upper surface of the base, and the support seats play a supporting role for the rotation of the threaded rod.

[0011] The inner wall of the internal thread moving block is slidably connected with a guide rod, and the two support seats are respectively fixedly connected to the two ends of the guide rod, and the guide rod plays a guiding role for the movement of the internal thread moving block.

[0012] Preferably, an auxiliary stabilizing mechanism is arranged above the base, and the auxiliary stabilizing mechanism includes a second electric push rod fixedly connected to the upper surface of the base and a U-shaped frame fixedly connected to the upper surface of the base, and the top of the second electric push rod is fixedly connected to a supporting plate, and the extension and retraction of the second electric push rod can drive the supporting plate to move up and down, thereby adjusting the central axis of the valve on the supporting plate to be aligned with the central axis of the conical sealing block.

[0013] The inner top wall of the above-mentioned U-shaped frame is fixedly connected with a third electric push rod, and the bottom end of the third electric push rod is fixedly connected with a lower pressure plate, and the lower pressure plate is adapted to the bearing plate. The extension and retraction of the third electric push rod drives the lower pressure plate to move up and down, and cooperates with the bearing plate to stabilize the valve between the bearing plate and the lower pressure plate.

[0014] The utility model provides a valve pressure detection tool, which has the following beneficial effects:

[0015] 1. The valve pressure detection tooling can adjust the angles of the three conical blocking blocks through the setting of the adjustment mechanism to adapt to two-way valves and three-way valves of various shapes. Compared with the existing conical blocking blocks that can only move in one direction, the angle of the conical blocking block can be adjusted according to the shape of the valve, and it has strong applicability.

[0016] 2. The valve pressure detection tooling places the valve on the carrier plate through the setting of the auxiliary stabilizing mechanism. The extension and retraction of the second electric push rod can drive the carrier plate to move up and down, so that the central axis of the valve on the carrier plate is aligned with the central axis of the conical sealing block, and then the third electric push rod is controlled to extend to move the lower pressure plate downward and cooperate with the carrier plate for auxiliary stabilizing clamping, so as to facilitate the subsequent sealing of the valve by the conical sealing block.
