Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a double-valve flap valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] The valves in the prior art need to control the flow and closing of water when in use. However, the traditional valves are sealed with a rubber ring structure after closing. When the rubber ring ages, water is easily infiltrated and cannot be tightly closed. At the same time, the valve is easily damaged when the water pressure is high during use, so it is inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to provide a double-valve disc valve, in which the valve stem drives the valve disc to rotate, and then the sealing ring is separated from the sealing groove to complete the separation, thereby facilitating the circulation of liquid. Similarly, during the closing process, the sealing ring and the sealing groove are sealed in cooperation to increase the sealing performance and improve the sealing effect.

[0005] To achieve the above-mentioned purpose, a double-valve flap valve is provided, comprising: a valve body, a valve stem is rotatably connected to the middle of the interior of the valve body, a valve flap is fixedly connected to the outside of the valve stem, an inclined plate is fixedly connected to one end of the interior of the valve body, a conical block is abutted on the inner side of the inclined plate, a tension spring is fixedly connected between the rear side of the conical block and the valve body, and a plurality of through holes are opened in the interior of the conical block.

[0006] According to the double-valve flap valve, the outer sleeve of the tension spring is provided with a bellows, and the two ends of the bellows are respectively fixedly connected to the conical block and the valve body.

[0007] According to the double-valve flap valve, a sealing ring is fixedly connected to one end of the outer side of the valve flap, sealing grooves are provided on both sides of the inner middle of the valve body, and the sealing ring and the sealing groove are sealed and matched.

[0008] According to the double-valve flap valve, a hand wheel is fixedly connected to the top end of the valve stem.

[0009] According to the double-valve flap valve, a fixing block is fixedly connected to the middle of the top end of the valve body, and the fixing block and the valve stem are rotatably matched.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The utility model is provided with a valve disc, a sealing ring and a sealing groove. The valve stem drives the rotation operation of the valve disc, and then the sealing ring is separated from the sealing groove to complete the separation, which is convenient for the circulation of the liquid. Similarly, during the closing process, the sealing ring and the sealing groove are sealed and cooperated to increase the sealing performance and improve the sealing effect.

[0012] 2. The utility model is provided with a conical block, an inclined plate, a through hole and a tension spring. When the water pressure is high, the conical block will collide with the inclined plate after being pushed by a strong pressure, thereby achieving a closing effect. At this time, the water source can penetrate and discharge through the through hole, which can effectively reduce the water pressure. When the water pressure stabilizes, the tension spring elastically pulls back to reset it for the normal circulation of the water source.

The inner side of the inclined plate 10 resists the conical block 8. When the water pressure is large, it will resist the conical block 8. At this time, the conical block 8 will resist the inclined plate 10 after being pushed by a strong pressure to achieve a closing effect. The water source can penetrate and discharge through the through hole 7, which can effectively reduce the water pressure. The rear side of the conical block 8 and the valve body 1 are fixedly connected A tension spring 12 is connected. After the water pressure stabilizes, the tension spring 12 elastically pulls back and resets it to facilitate the normal circulation of water. A plurality of through holes 7 are provided inside the conical block 8. During the circulation process, the water source will penetrate and circulate through the 5 through holes 7 inside the conical block 8 and the edge. A sealing ring 6 is fixedly connected to the outer end of the valve disc 4. Sealing grooves 9 are provided on both sides of the middle of the interior of the valve body 1, and the sealing ring 6 and the sealing groove 9 are sealed. A hand wheel 3 is fixedly connected to the top end of the valve stem 5. The hand wheel 3 in the prior art is rotated to drive the rotation operation of the valve disc 4. Then the sealing ring 6 is separated from the sealing groove 9 to complete the separation, which is convenient for the circulation of the liquid.

[0024] The outer sleeve of the tension spring 12 is provided with a bellows 11, and the bellows stretching is completed by the bellows 11, which is convenient for providing sealing and facilitating the use of the tension spring 12. The two ends of the bellows 11 are respectively fixedly connected to the conical block 8 and the valve body 1. The middle part of the top end of the valve body 1 is fixedly connected with a fixed block 2, and the fixed block 2 and the valve stem 5 are rotatably matched.

[0025] Working principle: when in use, the hand wheel 3 in the prior art is rotated, and the rotation drives the valve disc 4 to rotate. Then the sealing ring 6 disengages from the sealing groove 9 to complete the disengagement, which is convenient for the circulation of the liquid. During the circulation process, the water source will penetrate and circulate through the internal 5 through holes 7 and the edge of the conical block 8. When the water pressure is high, it will resist the conical block 8.
