[0002] The valve is a forced-seal shutoff device, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. However, existing valves only rely on the thick sealing gasket to abut against the end face of the water outlet to achieve shutoff, resulting in poor shutoff effect.

[0003] In order to solve the above technical problems, the existing patent document with announcement number (CN214197277U) discloses a high-sealing and shutoff valve, including components such as a valve body, a valve core, a valve stem and a handwheel. A water outlet is formed in the valve body, the valve core blocks the water outlet, and a thick sealing gasket made of hard plastic is fixed at the bottom of the valve core. The bottom end surface of the thick sealing gasket is provided with an installation groove with an isosceles trapezoidal cross-section inwardly, and an annular sealing ring with an isosceles trapezoidal cross-section is provided on the installation groove. The sealing ring extends out of the installation groove and abuts against the end face of the water outlet, and a sealing groove matching the sealing ring is provided on the end face of the water outlet, the depth of the sealing groove is greater than the height of the sealing ring extending out of the installation groove, and the sealing ring is fixed in the installation groove by an adhesive, and the sealing of the cross-section can be further improved by providing an arc-shaped sealing groove and an arc-shaped sealing portion, thereby improving the shutoff effect.

[0004] However, in the above-mentioned prior art, it is not convenient to control the flow rate of water, resulting in low practicality. Utility Model Content

[0020] According to the present specific embodiment, the first baffle 102 and the second baffle 103 are both fixedly connected to the valve body 101 and are located inside the valve body 101. The mounting plate 104 is fixedly connected to the first baffle 102 and the second baffle 103 respectively. The intercepting tube 105 has a plurality of circular holes 106. The intercepting tube 105 passes through the mounting plate 104 and is fixedly connected to the mounting plate 104. The cylinder 109 passes through the valve body 101 and is fixedly connected to the valve body 101. The adjusting assembly is fixedly connected, the adjusting assembly is arranged inside the cylinder 109, the first sealing gasket 107 is arranged inside the intercepting tube 105 and fits with the inner wall of the intercepting tube 105, the connecting rod 108 passes through the intercepting tube 105 and is slidably connected with the intercepting tube 105, one end of the connecting rod 108 is fixedly connected to the first sealing gasket 107, and the other end of the connecting rod 108 is fixedly connected to the adjusting assembly, and the two flanges 110 are fixed to the valve body 101 The first and second sealing gaskets 107 are connected and are respectively located at both ends of the valve body 101. The sealing assembly is arranged below the first sealing gasket 107. When in use, the interior of the valve body 101 is isolated by the first baffle 102, the second baffle 103 and the mounting plate 104, so that water can only flow through the multiple circular holes 106 on the intercepting tube 105. The connecting rod 108 is driven downward by the adjusting assembly, and the connecting rod 108 drives the first sealing gasket 107 to move downward. The circular holes 106 on the intercepting tube 105 are divided by the first sealing gasket 107, and the water can only flow through the circular holes 106 located below the first sealing gasket 107. As the first sealing gasket 107 moves downward all the time, the amount of water flowing is reduced until the first sealing gasket 107 is located below the multiple circular holes 106, thereby completely intercepting the water. Then, under the action of the sealing assembly, the intercepting effect of the first sealing gasket 107 is better.

[0021] Among them, the second sealing gasket 111 is fixedly connected to one end of the connecting rod 108 and fits with the inner wall of the cylinder 109, one end of the threaded rod 112 is rotatably connected to the second sealing gasket 111, the other end of the threaded rod 112 passes through the cylinder 109 and is threadedly matched with the cylinder 109, and the rotating member is arranged at the upper end of the threaded rod 112. When it is used, the threaded rod 112 is driven to rotate by the rotating member, and the threaded rod 112 drives the second sealing gasket 111 to move downward, and the second sealing gasket 111 drives the connecting rod 108 to move downward.

[0022] Secondly, the limiting ring 113 is sleeved on the outer side of the threaded rod 112 and fixedly connected to the threaded rod 112, the handwheel 114 is fitted with the upper surface of the limiting ring 113, and the nut 115 is sleeved on the outer side of the threaded rod 112 and threadedly connected to the threaded rod 112. When in use, the nut 115 is tightened to fix the handwheel 114 to the threaded rod 112.

[0023] At the same time, the sealing ring 116 is fixedly connected to the intercepting tube 105 and is located at the lower end of the intercepting tube 105. The clamping ring 118 is fixedly connected to the first sealing gasket 107 and is located on the bottom surface of the first sealing gasket 107. When in use, the first sealing gasket 107 moves downward, driving the clamping ring 118 to move downward until the clamping ring 118 is inserted into the sealing ring 116, thereby improving the interception effect of the water flow.

[0024] In addition, the sealing ring 116 has a groove 117 adapted to the snap ring 118 . When in use, the snap ring 118 is inserted into the groove 117 , thereby improving the sealing effect of the first sealing gasket 107 .

[0025] When using a shut-off valve of this embodiment, the first baffle 102, the second baffle 103 and the mounting plate 104 are used to isolate the interior of the valve body 101, so that water can only flow through the multiple circular holes 106 on the shut-off tube 105. The hand wheel 114 is rotated, and the hand wheel 114 drives the threaded rod 112 to rotate. The threaded rod 112 drives the second sealing gasket 111 to move downward, and the second sealing gasket 111 drives the connecting rod 108 to move downward, and the connecting rod 108 drives the first sealing gasket 107 to move downward. The shut-off valve 101 is closed by the first sealing gasket 107. The circular holes 106 on the cylinder 105 are divided, and the water flow can only flow from the circular holes 106 located below the first sealing gasket 107. As the first sealing gasket 107 moves downward, the amount of water flowing becomes smaller and smaller until the first sealing gasket 107 is located below multiple circular holes 106, thereby completely intercepting the water. At the same time, the first sealing gasket 107 drives the retaining ring 118 to move downward until the retaining ring 118 is inserted into the groove 117, thereby improving the interception effect of the water flow. This method can effectively solve the problem in the prior art that it is inconvenient to control the flow rate of water, resulting in low practicality.
