[0002] Butterfly valve, also called flap valve or butterfly valve, is a simple and commonly used control valve. Its working principle is to rotate the closing part (valve disc or butterfly plate). This closing part is in the shape of a disc and rotates around the valve shaft to achieve the purpose of opening, closing or regulating the fluid. The butterfly valve mainly plays a cutting and throttling role in the pipeline. It is used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. After the butterfly valve is produced, its air tightness parameters need to be tested, and it can be sold from the factory only if its performance is good.

A limiting groove is provided on the inner wall of the top limiting seat 8. The movable block 9 is slidably connected to the inner wall of the limiting seat 8 through the limiting groove, so that the movement of the movable block 9 is conveniently limited by the limiting groove, so that the movement of the movable block 9 remains in a relatively stable state. A second spring 10 is fixedly installed on the opposite side of the two movable blocks 9, and a connecting rod 11 is fixedly installed on the side of the movable block 9 away from the second spring 10. A limiting clamp 12 is fixedly installed on the side of the connecting rod 11 away from the movable block 9. The limiting clamp 12 is used to limit butterfly valves of different thicknesses to make their fixation more stable.

[0025] In this embodiment, the adjustment and detection mechanism also includes a rotary locking rod 13 rotatably connected to the front face of the top limit seat 8, a joystick 14 is fixedly installed on the front face of the rotary locking rod 13, a connecting block 15 is provided on the front face of the bottom limit seat 8, a card hole is provided on the front face of the connecting block 15, and the card hole is adapted to the rotary locking rod 13, so that the butterfly valve to be tested can be placed inside the limit seat 8 for testing through the cooperation between the connecting block 15 and the rotary locking rod 13, and a circulation component 16 is provided on the right side of the water tank 1, the circulation component 16 is composed of a circulating water pump and a water pipe, and the water pipe is a soft water pipe, so that the water pipe can be pulled conveniently to connect with the butterfly valve equipment for testing.

[0027] The working principle of the above embodiment is:

[0028] When using the hydraulic butterfly valve test bench, first fill the water tank 1 with clean water, then place the butterfly valve to be tested inside the bottom limit seat 8, then use the operating rod 14 to pull the movable plate 7 downward as a whole to drive the first spring 6 to move downward, so that the top limit seat 8 contacts the butterfly valve, and the throat is pulled downward by the operating rod 14 to drive the rotating locking rod 13 to engage with the connecting block 15, so as to achieve the fixation between the two limit seats 8. When the top limit seat 8 contacts the bottom limit seat 8, the limit clamping block 12 inside the top limit seat 8 abuts against the butterfly valve under the elastic force of the second spring 10, so that the detection device can perform fixed installation and detection of butterfly valves of different specifications and sizes. After the installation is completed, the circulation component 16 is connected to the butterfly valve, and the circulation component 16 is used to pass water into the butterfly valve to detect whether the air tightness meets the standard. The water discharged from the butterfly valve flows back to the water tank 1, so as to achieve the recycling of test water.
