Description

Technical Field

[0001] The utility model relates to valve detection equipment, in particular to a valve test bench. Background Art

[0002] A valve is a device used to control the flow of fluids. It can open, close or regulate the flow of liquids, gases or slurries flowing through pipes. Valves are widely used in both industrial and domestic applications. For example, they are used to control the flow of tap water in homes and to control various fluids in chemical reactions in the industrial field. After production, valves usually need to undergo a series of tests to ensure their performance and safety, including valve sealing tests.

[0003] As the name implies, the sealing test is to detect the sealing of the production valve to see if it leaks, so as to detect whether it is a qualified product. The existing test equipment for the valve detection operation is to place the valve to be tested at the detection station, and then the driving part drives the sealing part to seal the two ends of the valve, and then pass high-pressure gas into the valve to see if the valve leaks. The existing test equipment is often a single station, and the next valve can only be installed and tested after the previous valve is disassembled and assembled, which leads to a low test efficiency of the test equipment. Based on the above problems, the present invention is conceived. Utility Model Content

[0004] The utility model aims to provide a valve test bench, which has multiple operating stations to improve the test efficiency of the valve.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a valve test bench, including a test bench and a water reservoir formed on the test bench, a rotating frame rotatably arranged on the test bench and located above the water reservoir, at least two detection mechanisms are distributed on the rotating frame, a positioning assembly is formed between the rotating frame and the test bench, when the positioning assembly is in a positioning state, one of the detection mechanisms is submerged in the water reservoir, the detection mechanism includes two sealing disks, a detection station formed between the two sealing disks, a fastening member driving one of the sealing disks to move toward the other sealing disk, and an air intake branch pipe arranged on one of the sealing disks.

[0006] By adopting the above technical solution, the valve to be tested is installed at the testing station, and the sealing disk is driven to move by the fastener to achieve the sealing of the two ends of the valve by the sealing disk, and then the rotating frame is rotated to immerse the valve on one of the testing mechanisms into the water reservoir for testing and testing operations. Then the staff can disassemble and assemble the valves on the other testing mechanisms that are not immersed in the water reservoir to make up for the time wasted during the testing and replacement processes, so as to improve the test efficiency of the valve. The positioning component can well control the rotation positioning of the rotating frame to ensure the stable and orderly operation of each station.

[0007] It is further configured as follows: one of the inspection stations is a placement station, a supporting block is provided on one of the sealing disks corresponding to each of the inspection stations and the supporting block is arranged on an end surface of the sealing disk facing the other sealing disk, an adjusting locking assembly that moves radially along the sealing disk is provided between the supporting block and the sealing disk, when the supporting block moves to the placement station, the supporting block is located below the inspection station, and the outlet end of the air inlet branch pipe is located at the center of the sealing disk and is communicated with the inspection station.

[0008] By adopting the above technical solution, during the process of installing the valve at the placement station, one end of the valve is first placed above the support block, and the support block is used to bear the gravity formed by the valve during installation, so as to better adjust the valve position and align it with the sealing disk in the future, thereby facilitating the sealing effect of the two sealing disks behind on the valve, making the operation more convenient and labor-saving. The position of the support block is adjusted by setting an adjustment locking component to realize the support operation of valves of different sizes, ensuring the precise communication between the inner cavity of the valve and the outlet end of the inlet branch pipe.

[0009] It is further configured as follows: the adjustment locking assembly includes a slide groove formed on the outer peripheral wall of the sealing disk, a linkage rod slidably arranged in the slide groove and connected to the supporting block, and a locking bolt threadedly connected to an end face of another sealing disk opposite to the sealing disk and pressed against the linkage rod.

[0010] By adopting the above technical solution, the linkage rod drives the supporting block to move to adjust the position of the supporting block. After the position of the supporting block is adjusted, the supporting block can be fixed by tightening the linkage rod with a locking bolt; and this structure will not affect the sealing function of the sealing disk for the valve.

[0011] It is further configured as follows: each of the air intake branch pipes includes a first air intake section arranged in the sealing disk and a second air intake section arranged in the rotating frame and communicated with the first air intake section; an air intake main pipe is provided on the frame, the air intake main pipe forms a rotating seal with the rotating frame, and the air intake main pipe is communicated with the air intake branch pipes on the detection mechanism submerged in the water tank.

[0012] By adopting the above technical solution, this setting structure ensures that only the air intake branch pipe on the detection mechanism located in the water reservoir can be connected to the air intake main pipe. While simplifying the pipeline, it can also avoid the existing pipeline from interfering with the rotation of the rotating frame, thereby ensuring the feasibility of the structure.

[0013] The further configuration is as follows: the positioning assembly includes a positioning protrusion slidably arranged on the stand at one side of the rotating surface of the rotating frame, a driving spring driving the positioning protrusion to move toward one side of the rotating frame, and at least two positioning embedding grooves formed on the rotating frame, each of the positioning embedding grooves corresponding to a detection mechanism close to a side of the positioning protrusion, and when one of the detection mechanisms is submerged in the water reservoir, the positioning embedding groove corresponding to the detection mechanism corresponds to the positioning protrusion and is provided for embedding.

[0014] By adopting the above technical solution, when the detection mechanism is immersed in the water tank, the corresponding positioning groove and the positioning protrusion are exactly corresponding to each other, so that the positioning protrusion is embedded in the positioning groove under the action of the driving spring to form a positioning, and the separation of the positioning groove and the positioning protrusion is achieved by applying a large force to the rotating frame.

[0015] It is further configured as follows: the number of the detection mechanisms is two groups, and a water baffle is provided between two of the detection mechanisms.

[0016] By adopting the above technical solution, it is possible to avoid water spraying on workers installing the valves due to valve leakage during detection.

[0017] In summary, the utility model has the following beneficial effects: the utility model has multiple operating stations, thereby improving the test efficiency of the valve. BRIEF DESCRIPTION OF THE DRAWINGS
