Description

Technical Field

[0001] This utility model relates to the field of fluid control technology, specifically a press-type time delay valve. Background Technology

[0002] The push-button time-delay valve uses an internal delay mechanism to allow water to flow for a short period after the user presses the switch, then automatically closes the valve. This design satisfies the user's need for immediate water flow while automatically shutting off the water supply when the user leaves, effectively conserving water resources.

[0003] While existing time-delay valves can automatically close, they require repeated pressing when a longer water flow is needed, making them cumbersome and bulky. Therefore, a new type of push-button time-delay valve is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a press-type delay valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a push-button type delay valve, comprising: a valve body,

[0006] The propulsion assembly, located inside the valve body, is used to control the valve body's opening and closing to deliver water flow.

[0007] A rotating component, located on the inner wall of the valve body, is used to limit and fix the propulsion component;

[0008] The propulsion component includes:

[0009] The button is located on the outside of the valve body. The outer surface of the button is provided with a pointer groove. A push column is provided on one side of the button. A top column is provided on one end of the inner wall of the push column. A valve core is provided on one side of the top column.

[0012] As a specific solution in this application, the rotating component includes:

[0013] The retaining ring is located on the outer wall of the propulsion column and moves within the wide annular groove on the left side of the inner wall of the valve body.

[0014] As a specific solution in this application, the outer wall of one end of the propulsion column is provided with multiple limiting blocks, which move in the guide groove on the left side of the inner wall of the valve body. The outer wall of the valve body is provided with an inlet pipe and an outlet pipe respectively.

[0015] As a specific solution in this application, the valve body has multiple annular narrow grooves on the left side of its inner wall, the annular narrow grooves penetrate the guide groove, and a cavity is provided between the push column and the top column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This push-button time-delay valve, through the setting of a valve core, allows the opening to gradually overlap with the circular hole as the valve core moves within the hollow column, and then, under the action of a spring, it shifts back, thereby gradually and automatically closing the valve while water is flowing.

Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-6 As shown, this utility model provides a technical solution: a push-type time-delay valve, including a valve body 1, a propulsion assembly 2, a rotating assembly 3, etc. When controlling the water flow, water first enters the valve body 1 from the inlet pipe 102. Through the cooperation of the propulsion assembly 2 and the rotating assembly 3, the valve of the valve body 1 can be opened, so that the water flows out from the outlet pipe 101. During the water outflow process, the propulsion assembly 2 can gradually close the valve after it is opened, thereby achieving the effect of delaying and cutting off the water flow. The inlet pipe 102 and the outlet pipe 101 on the outside of the valve body 1 are used to guide the water. The rotating assembly 3 can control the valve to achieve a continuously open state when the water flow needs to be used for a long time. The propulsion assembly 2 is set on the inside of the valve body 1, and the rotating assembly 3 is set on the inner wall of the valve body 1.

[0029] like Figure 1-6As shown in the embodiment of this application, a button 202 is located on the outside of the valve body 1. A pointer groove 203 is provided on the outer surface of the button 202. A push post 212 is provided on one side of the button 202. A top post 213 is provided at one end of the inner wall of the push post 212. A valve core 209 is provided on one side of the top post 213. A circular hole 211 is provided through the valve core 209. A hollow column 206 is provided on the outer wall of the valve core 209. An opening 207 is provided on the hollow column 206. Limit rods 210 are provided on both sides of the inner wall of the hollow column 206. A sliding groove that cooperates with the limit rod 210 is provided on the outer wall of the valve core 209. A valve stem 214 is provided at one end of the valve core 209. 4. A circular plate 208 is provided at one end, and a sleeve 205 is provided on one side of the circular plate 208. A spring 201 is provided inside the sleeve 205, and a fixing post 204 is provided on the inner wall of the sleeve 205. Specifically, when it is necessary to control the closing of the valve body 1, the push post 212 is first moved linearly by pressing the button 202. During the movement of the push post 212, the top post 213 is simultaneously driven to push the valve core 209 to move. Initially, the circular hole 211 on the valve core 209 is misaligned with the opening 207 on the hollow post 206, and the valve core 209 moves along the limiting rod 210. The limiting rod 210 is used to limit the valve core 209. Positioning and guiding: As the valve core 209 gradually moves, the circular hole 211 on the valve core 209 gradually coincides with the opening 207. During this gradual coincidence, the valve body 1 guides the water, and as the overlap increases, the water flow velocity gradually increases. Simultaneously, the valve core 209 moves, driving the circular plate 208 to translate via the valve stem 214. During this movement, the circular plate 208 drives the sleeve 205 to move along the fixed column 204. The movement of the circular plate 208 compresses the spring 201. The spring 201 exhibits a certain deformation force during compression, thus generating... The deformation will rebound, which will cause the circular hole 211 and the opening 207 to misalign again, enabling the valve body 1 to close automatically, thereby achieving a delayed water flow closure effect. When the circular plate 208 and one end of the hollow column 206 are attached together again, the circular hole 211 and the opening 207 will be completely misaligned. It should be noted that the rear half of the hollow column 206 is fixed to the inner wall of the valve body 1. The fixing column 204 and the sleeve 205 are used to guide the spring 201 to ensure that the spring 201 will not deviate during compression. Under the action of the spring 201, the process of the circular hole 211 and the opening 207 gradually overlapping and then separating can achieve a delayed water flow closure effect.

[0030] like Figure 1-6As shown in the embodiment of this application, a fixing ring 302 is located on the outer wall of the propulsion column 212. The fixing ring 302 moves within the annular wide groove 304 on the left side of the inner wall of the valve body 1. A plurality of limiting blocks 303 are provided on the outer wall of one end of the propulsion column 212. The limiting blocks 303 move within the guide groove 306 on the left side of the inner wall of the valve body 1. A water inlet pipe 102 and a water outlet pipe 101 are respectively provided on the outer wall of the valve body 1. A plurality of annular narrow grooves 305 are provided on the left side of the inner wall of the valve body 1. The annular narrow grooves 305 penetrate the guide groove 306. A cavity 301 is provided between the propulsion column 212 and the top column 213. Specifically, the propulsion assembly 2 can realize the water flow from open to gradually closed state. When a long-term operation is required... When water is used, the push column 212 needs to be limited. When opening the valve body 1, this is achieved by pressing the button 202. The fixing ring 302 on the outer wall of the push column 212 is used to limit its movement. When the fixing ring 302 moves within the annular wide groove 304 on the inner wall of the valve body 1, it can limit the movement distance of the push column 212 and simultaneously fix the push column 212 relative to the inner wall of the valve body 1. Through the cavity 301 between the push column 212 and the top column 213, the front half of the hollow column 206 can be wrapped in it, so that the top column 213 pushes the valve core 209 further away, allowing the circular hole 211 on the valve core 209 to completely overlap with the opening 207. Under normal conditions, initially, the fixing ring 302 is close to the left side of the inner wall of the annular wide groove 304, and the spring 201 is in its normal state. When the opening 207 coincides with the circular hole 211, the fixing ring 302 is close to the right side of the inner wall of the annular wide groove 304. At this time, the front part of the hollow column 206 is located in the cavity 301, and one end of the sleeve 205 will abut against one end of the inner wall of the valve body 1. At this time, the spring 201 is in a compressed state, but has not reached its maximum value. During the valve opening process, the limiting block 303 on the outer wall of the push column 212 will move linearly along the guide groove 306. Considering that different people have different strengths, multiple annular narrow grooves 305 are set to accommodate the force exerted by people. When prolonged water usage is required, rotating button 202 will move limit block 303 from the guide groove 306 to the annular narrow groove 305, thereby limiting the displacement of push column 212. Under the limitation of push column 212, push column 212 is not affected by spring 201. That is, when push column 212 is limited, spring 201 will remain in a compressed state. When water usage ends and it is necessary to continue using push assembly 2 to close the valve, rotate pointer groove 203 to point to the center of water outlet pipe 101, and then release button 202. Button 202 will return to its original position under the action of spring 201, thereby closing the valve.
