Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a valve that is easy to clean. Background Technology

[0002] A valve is a mechanical device used to control the direction, pressure, and flow rate of fluids. It is widely used in industries such as petroleum, chemical, power, and water treatment to control the flow direction and pressure of media and ensure the normal operation of the system. In addition, valves are also commonly found in faucets, pressure reducing valves in gas stoves, and other equipment in daily life.

[0003] To filter out impurities in the water, existing valves typically have filters installed inside. However, prolonged use can cause these filters to become clogged, and failure to clean them promptly will directly affect the water flow. Currently, cleaning the filters requires disassembling the valve, making the cleaning process particularly cumbersome and inefficient.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a valve that is easy to clean.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a valve that is easy to clean, which can solve the problems of cumbersome cleaning process and low cleaning efficiency of existing valve filter screens.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a valve that is easy to clean, including: a valve housing and a valve core mechanism;

[0008] The valve housing is fixed with an inlet pipe and an outlet pipe on both sides, and a sedimentation chamber is provided at the bottom of the valve housing, with a drain outlet below the sedimentation chamber.

[0009] The valve core mechanism is installed inside the valve housing. The valve core mechanism includes a control valve core, which has a first inlet and a first outlet corresponding to the inlet and outlet connecting pipes, respectively. A second inlet is located above the first inlet on the same side of the control valve core, and a second outlet is located at the bottom of the control valve core. A filter screen is installed inside the valve core mechanism. A control rod is rotatably mounted on the control valve core. A control component is rotatably mounted inside the sedimentation chamber. The control component is slidably mounted to the control valve core. A worm gear is fixed on the control component. A worm adapted to the worm gear is installed inside the valve housing. A stop plug is installed at the drain outlet.

[0010] In one or more embodiments of this utility model, both the inlet and outlet water connection pipes are fixed with connecting flanges, and the valve is connected to the pipeline through the connecting flanges.

[0011] In one or more embodiments of this utility model, a rotating head is fixed at one end of the control rod inside the control valve core. The rotating head rotates inside the control valve core, and the rotation of the rotating head inside the control rod enables the control rod and the control valve core to be rotated. The control rod drives the control valve core to move up and down through the rotating head.

[0012] In one or more embodiments of this utility model, a threaded sleeve is fixed on the valve housing, and the control rod is threadedly connected to the threaded sleeve. When the control rod is rotated, the control rod drives the control valve core to move up and down through the threaded sleeve.

[0013] In one or more embodiments of this utility model, a first handle is installed at one end of the control rod outside the valve housing, and the control rod is rotated by the first handle.

[0014] In one or more embodiments of this utility model, a pair of locking strips are fixed on the control component, and a pair of locking strip grooves adapted to the locking strips are drilled on the control valve core. By sliding the locking strips in the locking strip grooves, the control component can always drive the control valve core to rotate after the control valve core moves upward.

[0015] In one or more embodiments of this utility model, a connecting rod is fixed on the water-stop plug, and the end of the connecting rod away from the water-stop plug is connected to the control valve core. When the control valve core moves up and down, the water-stop plug moves up and down through the connecting rod, so that the water-stop plug can be in an open or closed state at the drain outlet.

[0016] In one or more embodiments of this utility model, a cross-shaped fixing bracket is fixed on the control valve core, and the connecting rod rotates on the cross-shaped fixing bracket. The cross-shaped fixing bracket enables the connecting rod and the control valve core to be rotated. When the water stop plug is closed on the drain port, when the control valve core rotates, the cross-shaped fixing bracket and the connecting rod rotate, so that the water stop plug is always tightly closed on the drain port, preventing liquid leakage at the drain port.

[0017] In one or more embodiments of this utility model, the filter screen is simultaneously disposed between the first water inlet and the second water inlet, and between the second water outlet and the first water outlet. On the one hand, when water flows in from the first water inlet and out from the first water outlet, the water flows through the filter to remove impurities in the water. The filtered impurities fall downward into the second water outlet and then into the sedimentation chamber through the second water outlet. When cleaning, water flows in from the second water inlet and then washes the impurities in the reverse direction. The impurities then flow into the sedimentation chamber through the second water outlet and are finally discharged from the drain outlet.

[0018] In one or more embodiments of this utility model, the worm gear is provided with a second handle installed outside the valve housing, and the second handle is used to drive the worm gear to rotate.

[0019] Compared with existing technologies, this utility model, through its structural design, enables simple and quick cleaning of the filter screen inside the valve, effectively improving cleaning efficiency. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 6 As shown, a valve that is easy to clean in one embodiment of the present invention includes: a valve housing 1 and a valve core mechanism 2.

[0031] like Figures 1 to 2 As shown, an inlet pipe 101 and an outlet pipe 102 are fixed to both sides of the valve housing 1, respectively. Water flows into the valve housing 1 from the inlet pipe 101 and then flows out from the outlet pipe 102. A sedimentation chamber 104 is provided at the bottom of the valve housing 1, and a drain port 105 is provided below the sedimentation chamber 104. The sedimentation chamber 104 is used to deposit impurities filtered by the filter screen 206. When cleaning the filter screen 206, the impurities are discharged from the drain port 105. A connecting flange 103 is fixed to both the inlet pipe 101 and the outlet pipe 102, and the valve is connected to the pipeline through the connecting flange 103.

[0032] like Figures 1 to 6As shown, the valve core mechanism 2 is installed inside the valve housing 1. The valve core mechanism 2 includes a control valve core 201. The control valve core 201 is provided with a first inlet 202 and a first outlet 203 corresponding to the inlet connection pipe 101 and the outlet connection pipe 102, respectively. A second inlet 204 is provided on the same side above the first inlet 202 on the control valve core 201. A second outlet 205 is provided at the bottom of the control valve core 201. When water flows normally through this valve, water flows in from the inlet connection pipe 101 and passes through... The water enters the control valve core 201 through the first inlet 202, then flows out through the first outlet 203, and finally flows out of the valve through the outlet connection pipe 102. At the same time, the impurities filtered by the filter screen 206 fall downward into the second outlet 205 and are deposited in the sedimentation chamber 104. When cleaning, the control valve core 201 is moved downward to the second inlet 204 to correspond with the inlet connection pipe 101. At this time, water flows in from the second inlet 204 and flows out from the second outlet 205.

[0033] A filter screen 206 is installed inside the valve core mechanism 2, which is used to filter out impurities in the water. A control rod 207 is rotatably mounted on the control valve core 201. The control rod 207 is used to move the control valve core 201 up and down, moving it to a position corresponding to the first inlet 202 or the second inlet 204 on the inlet connection pipe 101. A control element 211 is rotatably mounted inside the sedimentation chamber 104. The control element 211 is slidably mounted on the control valve core 201. The control element 211 is used to rotate the control valve core 201, opening the first inlet 202 from its position corresponding to the inlet connection pipe 101, thereby closing the valve and terminating the water flow. A worm gear 212 is fixed on the control element 211. A worm 213 adapted to the worm gear 212 is installed inside the valve housing 1. When the worm 213 is rotated, it drives the control element 211 to rotate through the worm gear 212. A water-stop plug 217 is installed at the sewage outlet 105. The water-stop plug 217 is used to control the opening or closing of the sewage outlet 105.

[0034] like Figures 1 to 6As shown, a rotating head 209 is fixed to one end of the control lever 207, which is located inside the control valve core 201. The rotating head 209 rotates within the control valve core 201, and through its rotation within the control lever 207, the control lever 207 and the control valve core 201 are rotatably connected. The control lever 207, via the rotating head 209, drives the control valve core 201 to move up and down. A threaded sleeve 208 is fixed to the valve housing 1, and the control lever 207 is threadedly connected to the threaded sleeve 208. When the control lever 207 is rotated, the threaded sleeve 208 causes the control lever 207 to move the control valve core 201 up and down. A first handle 210 is installed at the end of the control lever 207 located outside the valve housing 1, and the first handle 210 drives the control lever 207 to rotate.

[0035] like Figures 1 to 6 As shown, a pair of retaining bars 218 are fixed on the control component 211, and a pair of retaining bar grooves 219 adapted to the retaining bars 218 are carved on the control valve core 201. The retaining bars 218 slide in the retaining bar grooves 219, so that after the control valve core 201 moves upward, the control component 211 can always drive the control valve core 201 to rotate.

[0036] like Figures 1 to 6 As shown, a connecting rod 216 is fixed to the stop plug 217. The end of the connecting rod 216 away from the stop plug 217 is connected to the control valve core 201. When the control valve core 201 moves up and down, the connecting rod 216 drives the stop plug 217 to move up and down, so that the stop plug 217 is in an open or closed state at the drain port 105. A cross bracket 215 is fixed to the control valve core 201. The connecting rod 216 rotates on the cross bracket 215, so that the connecting rod 216 and the control valve core 201 are rotatably set through the cross bracket 215. When the stop plug 217 is closed on the drain port 105, when the control valve core 201 rotates, the cross bracket 215 and the connecting rod 216 rotate, so that the stop plug 217 is always tightly closed on the drain port 105, preventing liquid leakage at the drain port 105.

[0037] like Figures 1 to 6As shown, the filter screen 206 is simultaneously located between the first inlet 202 and the second inlet 204, and between the second outlet 205 and the first outlet 203. When water flows in from the first inlet 202 and out from the first outlet 203, the filter screen 206 removes impurities. The filtered impurities fall downwards into the second outlet 205 and then into the sedimentation chamber 104. When cleaning the filter screen 206, water flows in from the second inlet 204, and then the impurities on the filter screen are flushed back. The impurities then flow into the sedimentation chamber 104 through the second outlet 205 and are finally discharged from the drain outlet 105. A second handle 214 is installed on the outside of the valve housing 1 to drive the worm gear 213 to rotate.

[0038] Working principle: When water flows normally through this device, the first inlet 202 and the first outlet 203 are in the corresponding states of the inlet connection pipe 101 and the outlet connection pipe 102, respectively. The stop plug 217 is closed on the drain outlet 105. The water flows into the first inlet 202 in the inlet connection pipe 101, and then passes through 106 to filter out impurities in the water. Then it flows into the outlet connection pipe 102 through the first outlet 203. At the same time, the filtered impurities fall downward into the second outlet 205, and then fall into the sedimentation chamber 104 through the second outlet 205. The impurities are deposited in the sedimentation chamber 104.

[0039] When cleaning is required, first close the valve, then drive the worm gear 213 to rotate via the second handle 214. The worm gear 213 drives the control component 211 to rotate via the worm wheel 212. The control component 211 drives the control valve core 201 to rotate, opening the first inlet 202 from the inlet connection pipe 101, thereby closing the valve. Then, drive the control rod 207 to rotate on the threaded sleeve 208 via the first handle 210. The threaded sleeve 208 causes the control rod 207 to move downward. The control rod 207 drives the control valve core 201 to move downward. When the control valve core 201 moves downward, it drives the stop plug 217 to move downward via the connecting rod 216, opening the stop plug 217 from the drain port 105. After opening, the water and impurities deposited in the sedimentation chamber 104 flow out of the valve housing 1 through the drain port 105.

[0040] When the control valve core 201 descends to a position where it can no longer descend, the first handle 210 stops rotating. At this time, the control valve core 201 drives the second water inlet 204 to move to a position where it is at the same horizontal level as the water inlet connection pipe 101. Then, the second handle 214 drives the worm gear 213 to rotate. The worm gear 213 drives the control component 211 to rotate through the worm wheel 212. The control component 211 drives the control valve core 201 to rotate, rotating the second water inlet 204 to a position corresponding to the water inlet connection pipe 101. When the second water inlet 204 is aligned with the water inlet connection pipe 101, water flows in through the second water inlet 204, and then the impurities on 106 are flushed in the reverse direction. The impurities then flow into the sedimentation chamber 104 through the second water outlet 205 and are finally discharged from the drain outlet 105, thus completing the cleaning. After cleaning, the control valve core 201 is moved to a position where the first water inlet 202 is aligned with the water inlet connection pipe 101 through the first handle 210 and the second handle 214, so that the water can flow normally.
