Description

Technical Field

[0001] The utility model relates to the technical field of valve clamps, in particular to a special clamp for valve pressure detection. Background Art

[0002] Nowadays, after small valves of various diameters are produced, the testing department needs to conduct water medium pressure testing on them to check for leakage. In fact, every valve needs to be tested before leaving the factory, and the workload of testing is relatively large.

[0003] When conducting a water pressure test on a valve, the existing technology mostly uses a threaded connection to connect the two ends of the valve, that is, both ends of each specification of the valve must be equipped with a fixture of the same thread size. The installation speed is extremely slow, and tools are needed to tighten the threads at both ends of the valve. When tightening the thread, it is also necessary to add sealing fillers such as winding hemp or raw tape. If leakage occurs after one installation, it has to be dismantled and reinstalled. The clamping connection of the valve is more troublesome, and the installation efficiency is low, which will lead to reduced detection efficiency. In addition, there are many types and specifications of valves. Every time a specification of a test piece is changed for testing, a specification of the fixture needs to be replaced, which is very inconvenient to use. For this reason, the present application proposes a special fixture for valve pressure testing. Utility Model Content

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a special fixture for valve pressure detection, including:

[0022] The mounting frame 1 is in the shape of a rectangular frame, and a rubber pad is fixed to the bottom of the mounting frame 1 to increase the stability of the mounting frame 1;

[0023] The clamp assembly comprises a fixing ring 2 fixed to the inner bottom of the mounting frame 1, the fixing ring 2 is fixed to the mounting frame 1 by glass glue, and a drainage hole is penetrated on the fixing ring 2 to drain the leaked water; the mounting frame 1 is installed with a first electric push rod 3 located just above the fixing ring 2, the output end of the first electric push rod 3 is fixedly connected to a mounting plate 8, a sealing plug 9 is installed on the mounting plate 8, and the sealing plug 9 is made of rubber; an alignment hose 10 is installed at the bottom of the sealing plug 9, the alignment hose 10 is coaxially arranged with the sealing plug 9, and the water supply hose 7 penetrates the sealing plug 9 and is connected to the alignment hose 10;

[0024] When in use, the valve is closed and placed on the mounting frame 1 and located in the fixing ring 2. Since the alignment hose 10 is provided and has a certain length, the valve is directly opposite to the sealing plug 9. Then the first electric push rod 3 is started to drive the mounting plate 8, the sealing plug 9 and the alignment hose 10 to move downward. The alignment hose 10 moves into the valve and bends. Finally, the sealing plug 9 abuts against the upper end of the valve. The valve can be fixed by the sealing plug 9 cooperating with the mounting frame 1. Since the sealing plug 9 is provided in an inverted truncated cone shape, it can be applied to the sealing positioning of various valves.

[0025] It also includes a pressure detection component; the pressure detection component includes a piston cylinder 5 fixed to the bottom of the mounting frame 1, a movable piston 11 is slidably connected in the piston cylinder 5, a second electric push rod 4 is installed on the mounting frame 1, a movable rod 6 is fixedly connected to the output end of the second electric push rod 4, the movable rod 6 is fixedly connected to the movable piston 11, and the piston cylinder 5 is connected to the alignment hose 10 through a water supply hose 7;

[0026] Wherein, the first electric push rod 3 and the second electric push rod 4 are controlled by separate switches respectively;

[0027] After positioning the valve, start the second electric push rod 4, which drives the moving rod 6 and the moving piston 11 to move downward, so that the clean water in the piston cylinder 5 can be transported to the valve through the water supply hose 7 and the alignment hose 10. Due to the valve sealing setting, the water pressure in the valve can be increased, so that the water pressure of the valve can be tested;

[0028] A pressure sensor may be installed on the piston cylinder 5 to detect changes in water pressure; or after a period of time, the valve may be removed to feel or observe whether there is water leakage, so as to understand the sealing performance of the valve after it is closed;

[0029] After the detection is completed, the output end of the second electric push rod 4 drives the moving rod 6 and the moving piston 11. Since the alignment hose 10 is bent in the valve, the water in the valve can be sucked into the piston cylinder 5, so that clean water can be recovered and it is convenient for the staff to handle the valve. It is not easy to cause a lot of clean water in the valve to spill out and make the workplace slippery.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
