Description

Technical Field

[0001] The invention relates to the technical field of stop valves, in particular to a straight-through electric fully enclosed ultra-clean stop valve free of oil pollution. Background Art

[0002] The straight-through stop valve is also easily contaminated by oil in the water during the process of controlling the flow of water. When oil impurities adhere to the baffle inside the stop valve, there is a gap between the baffle and the inner wall of the valve body due to the presence of oil, which causes the water blocking effect to deteriorate.

[0003] The defects of the existing stop valve are: 1. The prior art KR200442368Y1 discloses a stop valve, which does not have a structure for cleaning the valve core inside the stop valve. When oil adheres to the valve core of the stop valve, it is easy to cause a gap between the valve core and the inner wall of the valve body, causing the valve core to block the valve body, thereby making the valve body's water isolation effect worse. Therefore, a straight-through electric fully enclosed ultra-clean stop valve that is free of oil pollution and can clean the adhered impurities on the valve core inside the valve body is needed to solve this problem.

[0004] 2. The prior art JPS60215181A discloses a pressure-type stop valve, which does not have a heating structure. When oil stains adhere to the inside of the valve body, the water temperature is too low, which makes it difficult for the oil stains to fall off from the inner wall of the valve body. Therefore, a straight-through electric fully enclosed ultra-clean stop valve without oil stain pollution is needed to heat the water inside the valve body so that the oil stains can fall off more easily from the inside of the valve body to solve this problem.

[0005] 3. The prior art EP0150780A3 discloses a stop valve, which does not have a structure for keeping water inside the valve body. When the water inside the valve body is heated, if the water cannot be kept inside the valve body for a long time, the heated water will easily flow into the valve body and cause heat waste. Therefore, a straight-through electric fully enclosed ultra-clean stop valve that can control the heated water inside the valve body and prevent it from flowing away and is free of oil pollution is needed to solve this problem.

[0006] 4. The prior art CN110792787B discloses a stop valve, which does not have a structure for impacting water inside the valve body. The water inside the valve body does not flow and cannot impact the oil inside the valve body, so that the oil cannot effectively fall off from the inner wall of the valve body. Therefore, a straight-through electric fully enclosed ultra-clean stop valve without oil pollution is needed to solve this problem. Summary of the invention

The oil-free straight-through electric fully enclosed ultra-clean stop valve according to claim 5 is characterized in that: The top of the frame (2) is symmetrically mounted with an electric telescopic unit 2 (9), and the electric telescopic unit 2 (9) is electrically connected to the control unit (3), a push rod 2 (10) is mounted at the output end of the electric telescopic unit 2 (9), and one end of the push rod 2 (10) passes through the top inner wall of the frame 2 (8), a baffle 2 (11) is mounted at one end of the push rod 2 (10), and a frame 3 (12) is mounted on one side of the frame 2 (8).

7. The oil-free straight-through electric fully enclosed ultra-clean stop valve according to claim 6 is characterized by: A hydraulic telescopic unit 1 (13) is installed on one side of the frame body 3 (12), and the hydraulic telescopic unit 1 (13) is connected to the control unit (3) via an electrical signal, a piston rod 1 (14) is installed at the output end of the hydraulic telescopic unit 1 (13), a stop rod (15) is installed at one end of the piston rod 1 (14), and the stop rod (15) is located below the baffle plate 2 (11).

8. The oil-free straight-through electric fully enclosed ultra-clean stop valve according to claim 1 is characterized in that: A vent pipe (28) is installed on one side of the valve body (1), a compression pipe (29) is installed on the top of the vent pipe (28), and the compression pipe (29) and the vent pipe (28) are connected, and a vent hole (30) is symmetrically opened on the outer side of the compression pipe (29), a hydraulic telescopic unit 2 (31) is installed on the top of the compression pipe (29), and the hydraulic telescopic unit 2 (31) is connected to the control unit (3) by electrical signals, a piston rod 2 (32) is installed on the output end of the hydraulic telescopic unit 2 (31), and a compression plate (33) is installed on one end of the piston rod 2 (32), and the compression plate (33) is located inside the compression pipe (29).

9. A method for using a straight-through electric fully enclosed ultra-clean stop valve free of oil pollution according to any one of claims 1 to 8, characterized in that: The method of using the oil-free straight-through electric fully enclosed ultra-clean stop valve is as follows: S1, baffle plate 1 (7) and baffle plate 2 (11) move upward to allow water to flow through the valve body (1); S2. When the interior of the valve body (1) needs to be cleaned, the two baffles (11) are moved downward to store water between the two baffles (11) inside the valve body (1), and at the same time, the bottom of the baffle (7) is lowered to the middle position of the valve body (1), and then the ultrasonic generator (26) is turned on to perform ultrasonic cleaning on the interior of the valve body (1); S3, the frame body 4 (20) is driven to move left and right by the electric telescopic unit 3 (18), so that the rubber block (23) on the lifting rod (22) scrapes the dirt on the bottom of the baffle 1 (7), and the lifting rod (22) is squeezed by the baffle 1 (7) to move up and down, and at the same time, the spring (21) squeezes the lifting rod (22) moving downward toward the baffle 1 (7), so that the bottom of the circular baffle 1 (7) can be cleaned; S4. The compression plate (33) is driven downward by the hydraulic expansion unit 2 (31) to compress the air inside the compression tube (29), so that the compressed air enters the interior of the valve body (1) to impact the water, further increasing the cleaning power of the water on the oil stain inside the valve body (1).

10. The method for using the oil-free straight-through electric fully enclosed ultra-clean stop valve according to claim 9, characterized in that: The step S4 also includes the following steps: S41. When the weather is cold, the water inside the valve body (1) is heated by the heating unit (25), so that the oil stains can be more easily removed from the inner wall of the valve body (1) and the baffle plate (7).
