Description

Technical Field

[0001] This utility model relates to the field of valve pressure testing technology, and in particular to an adjustable valve pressure testing device. Background Technology

[0002] A valve is a device used to control the start and stop of various pipelines and equipment, as well as liquids and gases or liquids containing solid powders. It is usually composed of a valve body, valve cover, valve seat, opening and closing parts, drive mechanism, seals and fasteners. The opening and closing parts are raised, lowered, slid, or swung by the drive mechanism to change the size of the flow channel area. In the valve production process, in order to ensure normal use later, it is often necessary to test the valve with a pressure testing device after production is completed to ensure that the valve has an airtight effect. Utility model patent CN217542385U discloses a rapid valve pressure testing device, relating to the field of pressure testing devices. This utility model includes a support mechanism, a workbench, a pressure testing mechanism, and a detection component disposed inside the workbench for pressurizing the valve. A collection mechanism is installed on one side of the workbench to collect water flowing from the valve. A support plate is disposed inside the workbench, and a groove is provided on the upper surface of the workbench, with the support plate connected to the groove. A support frame is disposed inside the workbench, and a pressure testing pump is installed on the upper part of the support frame, with a water inlet pipe installed at one end of the pressure testing pump. This utility model's rapid valve pressure testing device places the valve on a placement plate, with the other end of the valve connected to a clamping head. One end of a tap water plastic pipe is connected to a tap water supply, and the main compressed air pipe is connected to a compressed air compressor. By starting the compressed air compressor, compressed air is delivered to the main compressed air pipe, and then enters the cylinder through branch pipes to provide power to the cylinder.

[0003] However, this utility model still has shortcomings. For example, when the valve is fixed to the front end of the cylinder with a flange during valve pressure testing, the flange is limited to a single model of valve due to its specific model and specifications. This fixed combination method limits the applicability of the pressure testing device and makes it impossible to flexibly adjust it to meet the testing requirements of different models of valves. Therefore, there is an urgent need for a solution that can alleviate the above problems. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable valve pressure testing device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable valve pressure testing device includes a test bench, a pneumatic pump, and a sealing gasket. A control auxiliary mechanism is provided at the upper end of the test bench.

[0007] Preferably, the main body material of the sealing gasket is rubber, one end of the fixing frame is fixedly connected to one end of the support frame, one end of the spring is fixedly connected to the other end of the support frame, and the other end of the spring is fixedly connected to one end of the baffle near the outer side of the sliding rod.

[0008] Preferably, the lower end of the internal threaded ring is in contact with the upper end of the fixing frame, and the center lines of the drive shaft, the internal threaded ring, and the knob are located on the same straight line.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-5 As shown, an adjustable valve pressure testing device includes a test bench 1, a pneumatic pump 2, and a sealing gasket 3. A control auxiliary mechanism 7 is provided at the upper end of the test bench 1. The control auxiliary mechanism 7 includes a fixing block 71 fixedly connected to the upper end of the test bench 1. A support frame 72 is fixedly connected to the upper end of the fixing block 71. A sliding rod 73 is slidably connected to the inner side of the support frame 72. A clamping piece 74 is fixedly connected to one end of the sliding rod 73. A sealing gasket 75 is fixedly connected to one end of the clamping piece 74. A contact frame 76 is fixedly connected to the other end of the clamping piece 74 near the upper side of the sliding rod 73. An eccentric disk 77 is drivenly connected to the inner side of the contact frame 76. A drive shaft 78 is fixedly connected to the inner side of the eccentric disk 77. A fixing frame 79 is movably connected to the outer side of the drive shaft 78 near the upper side of the eccentric disk 77. A spring 710 is sleeved on the outer side of the sliding rod 73 near the support frame 72. An internal threaded ring 711 is threadedly connected to the outer side of the drive shaft 78 near the upper side of the fixing frame 79.

[0016] In this embodiment, a baffle 712 is fixedly connected to one end of the sliding rod 73, a knob 713 is fixedly connected to the upper end of the drive shaft 78, the main body of the sealing gasket 75 is made of rubber, one end of the fixing frame 79 is fixedly connected to one end of the support frame 72, one end of the spring 710 is fixedly connected to the other end of the support frame 72, the other end of the spring 710 is fixedly connected to one end of the baffle 712 near the outside of the sliding rod 73, the lower end of the internal thread ring 711 is in contact with the upper end of the fixing frame 79, and the axis of the drive shaft 78, the internal thread ring 711, and the knob 713 are located on the same straight line.

[0017] Specifically, rotating knob 713 causes drive shaft 78 to rotate, which in turn causes eccentric disc 77 to rotate. This eccentric disc 77 then pushes clamping plate 74 within contact frame 76, causing clamping plate 74 to pull sliding rod 73. Sliding rod 73 compresses spring 710 via baffle 712, bringing sealing gasket 75 into contact with the other end of the valve. Clamping plate 74 tightly presses sealing gasket 75 against one end of the valve, causing deformation of sealing gasket 75 and sealing washer 3 under pressure. This seals both ends of the valve. Then, the internal threaded ring 71 is turned in the opposite direction. 1. Moving the internal threaded ring 711 downwards causes it to contact the fixed frame 79, thus limiting the rotation of the fixed frame 79. This tightly secures the valve between the sealing gasket 75 and the sealing washer 3. By rotating the drive shaft 78, the eccentric disc 77 rotates, pushing the clamping plate 74 to move. This causes the sealing gasket 75 to contact the valve, making the valve, sealing gasket 75, and sealing washer 3 come into contact. This allows for easy control of the clamping plate 74's movement distance for sealing the valve, thus adapting to different valve models and greatly increasing their pressure testing range.

[0018] In this embodiment, the air pressure pump 2 is installed on the upper end of the test bench 1 near the fixed block 71, and the sealing gasket 3 is installed at one end of the air pressure pump 2. The sealing gasket 3 and the sealing gasket 75 correspond to each other. The main body material of the sealing gasket 3 is rubber. The equipment box 4 is fixedly connected to the upper end of the test bench 1 near the rear side of the fixed block 71. An indicator light 5 is installed on the upper end of the equipment box 4. A ventilation groove 6 is opened at the front end of the test bench 1.

[0019] Specifically, start the air pump 2 to pressurize the valve, and then you can test the valve.

[0020] Working principle: In use, the worker first places the valve to be pressure tested between the sealing gasket 75 and the sealing washer 3, aligning the two ends of the valve with the sealing gasket 75 and the sealing washer 3. Then, the valve is placed against one end of the sealing washer 3. Next, the internal threaded ring 711 is turned, causing it to move upwards along the drive shaft 78. Then, the knob 713 is turned, causing the drive shaft 78 to rotate. This causes the drive shaft 78 to rotate, and the eccentric disc 77 to push the clamping plate 74 within the contact frame 76. This causes the clamping plate 74 to pull the sliding rod 73, and the sliding rod 73 compresses the spring 710 via the baffle 712. This brings the sealing gasket 75 into contact with the other end of the valve, allowing the clamping plate 74 to tightly press the sealing gasket 75 against one end of the valve, thus applying pressure to the sealing gasket 75 and the sealing washer 3. The deformation allows for sealing at both ends of the valve. Then, the internal threaded ring 711 is reversed, causing it to move downwards and contact the fixed bracket 79. This restricts the rotation of the fixed bracket 79, tightly securing the valve between the sealing gasket 75 and the sealing washer 3. The air pump 2 is then activated to pressurize the valve, allowing for pressure testing. Rotating the drive shaft 78 rotates the eccentric disc 77, which in turn pushes the clamping plate 74, causing the sealing gasket 75 to contact the valve. This allows for easy control of the clamping plate 74's movement distance for sealing, accommodating different valve models and significantly increasing the pressure testing range.
