Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve which is easy to clean. Background Art

[0002] Valves are control components in fluid conveying systems. They have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems can be 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. Therefore, valves are widely used.

[0003] Most of the existing valves are composed of components such as valve body pipes, threaded rods and baffles. During the use of the existing valves, the water flow in the pipes often carries some rust fragments or some foreign particles, and these foreign particles will remain at the valve. If they are not cleaned for a long time, they will accumulate and cause the valve to be blocked, affecting the normal transportation of the pipeline. At the same time, most of the existing valves have openings at the bottom to manually flush the inside of the valve body, but the space on the inner wall of the valve body is relatively narrow, making it inconvenient to clean. Therefore, we propose a valve that is easy to clean in order to solve the above problems. Utility Model Content

[0022] See also Figure 1-6 The utility model provides a technical solution: a valve that is easy to clean, including a valve body 1, a threaded rod 2, a baffle plate 3, a side baffle plate 4, a telescopic rod 5, a first slide groove 6, a side fixing rod 7, a first fixing groove 8, a first fixing ring 9, a turbine 10, a second fixing groove 11, a second fixing ring 12, a brush 13, a scraper 14, a connecting fixing rod 15, a sealing cover 16 and a support rod 17.

[0023] The threaded rod 2 is threadably arranged on the top of the valve body 1, so that the blocking plate 3 and the telescopic rod 5 at the bottom are driven to move up and down by the rotation of the threaded rod 2, and the telescopic rod 5 forms a telescopic structure in the first slide groove 6 inside the support rod 17 through the threaded rod 2, so that the telescopic rod 5 can drive the blocking plate 3 at the top to move to adjust the buckle size of the valve without affecting the support rod 17.

[0024] The side fixing rods 7 are evenly spaced on the outer surface of the support rod 17, and a hollow slide groove is provided on the inner side of the side fixing rod 7, so that the connecting fixing rod 15 at the bottom of the sealing cover 16 can pass through the side fixing rod 7, limiting and fixing the hollow fixing blocks in the first fixing groove 8 and the second fixing groove 11 on the side fixing rod 7.

[0025] The first fixing ring 9 and the second fixing ring 12 are respectively provided with fixing blocks arranged at the same intervals on the inner side, so that the fixing blocks can be connected with the fixings on the side fixing rod 7, and hollow sliding grooves are provided in the fixing blocks, so that the connecting fixing rod 15 can penetrate the side fixing rod 7 and the fixing blocks connected to the fixing grooves of the connecting fixing rod 15, so as to limit and fix the first fixing ring 9 and the second fixing ring 12 respectively.

[0026] The first fixing groove 8 and the second fixing groove 11 are respectively arranged on the upper and lower sides of the side fixing rod 7, and the length of the fixing groove is the same as the length of the fixing block inside the first fixing ring 9 and the second fixing ring 12, so as to facilitate the connection with the fixing block inside the first fixing ring 9 and the second fixing ring 12, thereby fixing the inner fixing block on the side fixing rod 7.

[0027] The bottom of the connecting fixing rod 15 is connected to the sealing cover 16 through a rotating shaft, so that the connecting fixing rod 15 passes through the side fixing rod 7 so that it can rotate along with the rotation of the support rod 17, and the connecting fixing rod 15 passes through the side fixing rod 7 and the fixing blocks respectively arranged on the inner sides of the first fixing ring 9 and the second fixing ring 12 form a locking structure, and the fixing blocks on the inner sides of the first fixing ring 9 and the second fixing ring 12 are fixed to the side fixing rod 7 through the connecting fixing rod 15, thereby fixing the first fixing ring 9 and the second fixing ring 12.

[0028] The length of the telescopic rod 5 and the first slide groove 6 is greater than the diameter of the water outlet pipe, so that the telescopic rod 5 can drive the blocking plate 3 and the side baffle plate 4 to seal the water outlet and the water inlet respectively, so that there is no medium being transported inside the valve body 1 during maintenance.

[0029] Working principle: When using the easy-to-clean valve, first, when water flows into the valve body 1 from the water inlet pipe with impurities, the water will flow along the valve body 1 and then flow out from the water outlet pipe. During the whole process, some impurities will remain in the valve body 1. At the same time, the flow of water will drive the turbine 10 connected to the upper side of the support rod 17 to rotate, so that the turbine 10 drives the support rod 17 and the brush 13 connected to the support rod 17 at the lower side and the scraper 14 at the bottom of the brush 13 to rotate, so that the impurities falling into the valve body 1 are lifted up and brought out of the valve body 1 along with the flow of water.

[0030] When inspecting the valve body 1, first rotate the threaded rod 2 so that the threaded rod 2 drives the baffle plate 3 and the side baffle plate 4 at the bottom of the baffle plate 3 to move downward, and at the same time, the telescopic rod 5 at the bottom of the side baffle plate 4 will also shrink and enter the first slide groove 6 inside the support rod 17, until the telescopic rod 5 reaches the bottom of the first slide groove 6, so that the baffle plate 3 and the side baffle plate 4 respectively block the water inlet pipe and the water outlet pipe, open the sealing cover 16 fixed by bolts, and lift the sealing cover 16 by hand. After removing the bolts, move the sealing cover 16 downward, so that the support rod 17 extends through the telescopic structure composed of the first slide groove 6 and the telescopic rod 5, and extends the rotating cleaning structure composed of the first fixing ring 9, the turbine 10, the second fixing ring 12, the brush 13, and the scraper 14. The valve body 1 is extended to facilitate cleaning of the turbine 10, the brush 13 and the scraper 14. When replacement is required, the sealing cover 16 is pulled downward so that the connecting fixing rod 15 is pulled out along the hollow slide groove in the side fixing rod 7, thereby releasing the fixing of the fixing blocks respectively arranged on the inner sides of the first fixing ring 9 and the second fixing ring 12, and then the first fixing ring 9 and the second fixing ring 12 are rotated respectively so that the fixing blocks respectively arranged on the inner sides of the first fixing ring 9 and the second fixing ring 12 are disengaged from the first fixing groove 8 and the second fixing groove 11 on the side fixing rod 7, and then they are moved downward one by one, so that the turbine 10 and the brush 13 can be removed for replacement or inspection, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
