Description

Technical Field

[0001] The utility model mainly relates to the technical field of discharge valves, in particular to an anti-blocking manual discharge valve. Background Art

[0002] The discharge valve has good mechanical properties and corrosion resistance, can prevent the medium from replacing metal ions and affecting the contamination of products, and has a smooth surface, wear resistance, and a certain degree of thermal stability. The discharge valve dedicated to the bottom of the kettle can play a good regulating role, conveniently discharge the liquid inside the equipment, and improve the use effect of the kettle body.

[0003] For example, Chinese patent publication number CN217301772U discloses an anti-clogging structure for a discharge valve dedicated to the bottom of a kettle, including a discharge valve body and a valve port installed on the discharge valve body, a chamber connected to the discharge valve body is provided inside the valve port, a sleeve is embedded inside the chamber, and a filter hole is provided at one end of the sleeve inserted into the valve port. The above application sets a chamber, a sleeve, a filter hole, a limit plate and a fastening pad, so that when in use, the sleeve can be inserted into the chamber inside the valve port, and the limit plate can contact the outer wall of the valve port to achieve a supporting effect. The clogging problem of the discharge valve is often caused by the agglomeration, accumulation, adhesion, etc. of the material, but the liquid in the above application needs to pass through the filter hole to achieve the flow effect. After the liquid agglomerates, it is easy to clog the filter hole, affecting the liquid flow effect. Utility Model Content

[0013] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] The cleaning part arranged on the sealing plug of the utility model can clean the inner wall of the valve pipe when the sealing plug moves up and down. Since the cleaning part directly contacts the inner wall, dirt, sediment and the like attached to the inner wall can be effectively removed, thereby improving the cleaning effect and preventing blockage.

[0015] The cleaning part on the sealing plug of the utility model can be cleaned during the operation of the valve without stopping or disassembling the valve, which reduces the time and workload of maintenance. Dirt, sediments, etc. on the inner wall of the valve body will increase the friction resistance of the pipeline, affect the flow of the fluid, and may cause the valve to get stuck or operate poorly, or even cause safety hazards such as leakage. By cleaning the inner wall through the support mechanism and the cleaning part, hidden dangers can be eliminated in time and the safety of the valve can be improved.

Example

[0027] Refer to the attached Figures 1 to 4 A manual discharge valve with anti-clogging comprises a valve body 1, a valve stem 2 is mounted on the valve body 1, a sealing plug 3 is arranged in the valve body 1, the valve stem 2 is connected with the sealing plug 3, a cleaning part 4 is arranged on the sealing plug 3, the cleaning part 4 is made of rubber, and cleaning convex patterns are arranged on the outer side of the cleaning part 4.

[0028] The cleaning part 4 has a mounting cavity 5, such as Figure 3 As shown, it is a schematic diagram of the internal structure of the installation cavity 5 (the figure is a schematic diagram after removing the top cover of the sealing plug 3), an annular support frame 6 is arranged in the installation cavity 5, and a plurality of support mechanisms 8 are arranged on the support frame 6 at equal distances, and the support mechanism 8 is used to push the cleaning part 4 to open outward to clean the valve body 1.

[0029] The supporting mechanism 8 includes a sleeve 81 installed on the supporting frame 6, a slide rod 82 is slidably installed in the sleeve 81, a supporting plate 83 is provided at one end of the slide rod 82, and a limiting block 84 is provided at the other end. The supporting plate 83 is in contact with the cleaning part 4, and a return spring 85 is provided between the limiting block 84 and the sleeve 81. The return spring 85 is sleeved on the slide rod 82, and the slide rod 82 is connected to the driving mechanism, and the driving mechanism is used to push the slide rod 82 to move.

[0030] The driving mechanism includes a push rod 9 and a truncated cone push block 7 connected to each other, a roller 86 is installed on the limit block 84, the roller 86 is attached to the side of the truncated cone push block 7, the push rod 9 is slidably installed inside the valve stem 2, and the push rod 9 is perpendicular to the slide rod 82. The upper end of the push rod 9 is provided with a threaded portion 91, and the valve stem 2 is provided with an internal thread matched with the threaded portion 91.

[0031] Working principle:

[0032] By rotating the threaded portion 91 of the push rod 9, the push rod 9 moves downward under the action of the internal thread of the valve stem 2, and the push rod 9 pushes the conical push block 7 to move downward. Since the side of the conical push block 7 is an inclined surface, it will push the sliding rod 82 to move outward under the action of the roller 86, so that the support plate 83 pushes the cleaning part 4 to open outward. The opened cleaning part 4 is slightly larger than the diameter of the sealing plug 3, and then the valve stem 2 is rotated to drive the sealing plug 3 to move up and down, thereby cleaning the inner wall of the valve body 1. After cleaning, the threaded portion 91 is rotated in the opposite direction, the conical push block 7 moves up, and the reset spring 85 drives the support plate 83 and the cleaning part 4 to reset.

[0033] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
