[0015] Figure 2 It is a schematic enlarged view of part A in an embodiment of the present utility model. Detailed Embodiment
[0016] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0017] Refer to Figure 1-2, what is disclosed in the embodiment of the present utility model is: a water supply pipeline exhaust valve, including a valve body 1, a valve cover 10 provided on the valve body 1, a water inlet passage 2 opened on the valve body 1, a sliding pipe 4, and a reciprocating lead screw 13. The sliding pipe 4 slidably penetrates through the valve cover 10. One end of the sliding pipe 4 is provided with a floating ball 3 and the floating ball 3 is located inside the valve body 1. The other end of the sliding pipe 4 penetrates out of the valve cover 10. The floating ball 3 and the water inlet passage 2 are in the same axial position. A plurality of exhaust passages 5 are opened on the sliding pipe 4 from top to bottom. A dust-proof cover 9 for preventing external impurities from entering the exhaust passage 5 is provided on the valve cover 10. A filter screen 11 for preventing impurities in the water flow from entering the inside of the valve body 1 and blocking the inside of the valve body 1 and the exhaust passage 5 is provided in the water inlet passage 2. The reciprocating lead screw 13 rotatably penetrates through the valve body 1. One end of the reciprocating lead screw 13 is located in the water inlet passage 2. The other end of the reciprocating lead screw 13 penetrates out of the valve body 1. A reciprocating block 12 is provided on the reciprocating lead screw 13. A brush is provided on the reciprocating block 12. The brush abuts against the filter screen 11. A driving motor for driving the reciprocating lead screw 13 to rotate is provided on the valve body 1. Among them, when in use, when exhausting, water flows into the exhaust valve, thereby pushing the floating ball 3. The floating ball 3 drives the sliding pipe 4 to slide upward. The upper end of the sliding pipe 4 leaves the valve cover 10. Gas enters the sliding pipe 4 from the lower exhaust passage 5 and is discharged from the upper exhaust passage 5 to the outside of the valve body 1, thereby achieving the exhaust effect. Exhausting through the sliding pipe 4 has a simple structure and good exhaust effect, not only saving the manufacturing cost but also saving the maintenance cost. The dust-proof cover 9 can prevent impurities from entering through the exhaust passage 5 and blocking the sliding pipe 4, and will not affect the exhaust of the sliding pipe 4. The filter screen 11 in the water inlet passage 2 can filter the impurities entering the inside of the valve body 1, thereby preventing the impurities from entering the inside of the valve body 1 and accumulating inside the valve body 1, causing the inside of the valve body 1 to rust and block, and at the same time will not enter the exhaust passage 5 and block and accumulate the exhaust pipe. When the filter screen 11 filters, the driving motor works to drive the reciprocating lead screw 13 to rotate. The reciprocating lead screw 13 rotates to drive the reciprocating block 12 to slide back and forth. The brush on the reciprocating block 12 brushes the impurities on the filter screen 11, thereby improving the filtering ability of the filter screen 11 and preventing the impurities from blocking the filter screen 11.
[0018] In order to facilitate the installation and disassembly of the sliding pipe 4 and limit the downward sliding distance of the sliding pipe 4, a limiting head 6 is threadedly connected to the end of the sliding pipe 4. The limiting head 6 abuts against the valve cover 10 after sliding downward with the valve cover 10.
[0019] In order to prevent the floating ball 3 from hitting the valve cover 10 and being damaged when floating upward, an elastic plate 7 that prevents the floating ball 3 from being hit is provided at the upper end of the sliding pipe 4 where the floating ball 3 is located. The elastic plate 7 abuts against the valve cover 10 after sliding upward.
[0020] In order to ensure the sealing performance and improve the sliding of the sliding tube 4, a sliding seal sleeve 8 is provided on the valve cover 10, and the sliding tube 4 is slidably disposed through the sliding seal sleeve 8.
[0021] The foregoing has shown and described the basic principles, main features and advantages of the present invention.
