Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve with reduced opening and closing time. Background Art

[0002] The opening and closing part of the knife-type gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The manual knife-type gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The most commonly used mode of the gate valve is that the two sealing surfaces form a wedge shape. The wedge angle varies with the valve parameters.

[0003] The knife-type gate valve in the prior art needs to rotate the valve stem multiple times to achieve the purpose of full opening or closing when opening and closing, resulting in a long opening and closing time. There is a need to reduce the opening and closing time.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Utility Model Content

[0005] The purpose of the utility model is to design a valve that can be fully opened or closed by reducing the number of rotations, in which the movement direction of the gate is perpendicular to the direction of the fluid, and which reduces the opening and closing time, so as to solve the above-mentioned shortcomings in the technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve that reduces the opening and closing time, comprising a valve body, a water inlet pipe fixedly connected to one end of the valve body, a water outlet pipe fixedly connected to the other end of the valve body, and a valve core installed in the valve body, the valve body is configured to be disc-shaped, and its cross-section is configured to be U-shaped, the valve core is composed of an active disk and a sealing disk, and the active disk and the sealing disk are respectively provided with a first water hole and a second water hole of matching shapes in an annular array, and by rotating the active disk, the valve is opened when the first water hole and the second water hole partially overlap, and the valve is closed when they do not overlap at all.

[0007] Preferably, the sealing disk is close to the side of the active disk, and the side of each second water hole is chamfered to form an inclined groove. The active disk is close to the side of the sealing disk, and a protrusion matching the shape of the inclined groove is fixedly connected between each two first water holes. The sealing disk is arranged inside the valve body near the side of the water inlet pipe, and the active disk is arranged inside the valve body near the side of the water outlet pipe.

[0008] Preferably, the axial spacing inside the valve body is greater than or equal to the sum of the thickness of the active disk, the thickness of the sealing disk and the thickness of the bump.

[0009] Preferably, a non-circular guide groove is opened inside the sealing disk, and a guide column is slidably connected inside the guide groove. The guide column is fixedly connected to a positioning piece fixedly connected to the inner wall of the water inlet pipe at one end away from the sealing plate. The sealing disk is limited to axial movement by the guide column and the guide groove.

[0010] Preferably, the positioning member is fixedly connected to a spring on one side close to the sealing disk, and the spring is fixedly connected to a push piece on one end away from the positioning member. The push piece is penetrated by the guide column and is slidably connected to the guide column, and the push piece fits the sealing disk.

[0011] Preferably, an arcuate groove is formed on a side of the valve body away from the sealing disk, and a toggle handle fixedly connected to the side wall of the active disk is fixedly connected to the inside of the arcuate groove.

[0012] Preferably, the arc length of the arc groove matches the size of the protrusion. When the toggle handle is located at one end of the arc groove, the first water hole and the second water hole completely overlap. When the toggle handle is located at the other end of the arc groove, the first water hole and the second water hole completely do not overlap.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. To open or close the valve, simply push the handle in the arc groove from one end to the other, so that the first water hole and the second water hole completely overlap or do not overlap, and the valve can be opened and closed quickly.

[0015] 2. To close the valve, move the toggle handle from one end of the arc groove to the other. When the protrusion is stuck in the inclined groove, the first water hole and the second water hole will not overlap at all. At this time, the water at the water inlet pipe will press the sealing disk against the active disk. At this time, with the help of water pressure and the elastic force of the spring, the sealing disk and the active disk are tightly fitted together to close the valve.

[0016] 3. This product can adjust the stroke of the valve when it is fully opened or closed according to the number of the first water holes and the second water holes distributed in a circular array. The greater the number, the shorter the rotation stroke and the required opening and closing time will be. Compared with the manual knife-type gate valve, which requires multiple turns of the valve stem, the opening and closing time is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to help those skilled in the art better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example:

[0027] like Figure 1-4As shown, it includes a valve body 1, a water inlet pipe 2 fixedly connected to one end of the valve body 1, and a water outlet pipe 3 fixedly connected to the other end of the valve body 1. A connecting piece is fixedly connected to the water inlet pipe 2, and a guide column 10 is fixedly connected to the side of the connecting piece close to the valve body 1. A push piece 13 and a sealing disk 402 are passed through the outside of the guide column 10. A spring 12 is fixedly connected between the push piece 13 and the connecting piece. An active disk 401 is provided on the side of the sealing disk 402 away from the connecting piece. The active disk 401 and the sealing disk 402 are both arranged in the valve body 1, and the sealing disk 402 and the active disk 401 are respectively provided with There are multiple first water holes 5 and second water holes 6, and the sealing disk 402 is close to the side of the active disk 401. The side of each second water hole 6 is chamfered to form an inclined groove 7. The active disk 401 is close to the side of the sealing disk 402. A protrusion 8 matching the shape of the inclined groove 7 is fixedly connected between each two first water holes 5. An arc groove 14 is opened on the side wall of the valve body 1. A toggle handle 15 fixedly connected to the side wall of the active disk 401 is slidably connected in the arc groove 14. The active disk 401 blocks the arc groove 14 from communicating with the inner cavity of the water outlet pipe 3, thereby forming a seal.

[0028] When the valve is to be opened, the protrusion 8 is stuck in the inclined groove 7, and the user holds the toggle handle 15 and slides it toward the other end of the arc groove 14. The toggle handle 15 drives the active disk 401 to rotate in the valve body 1. Due to the matching of the inclined surfaces between the inclined groove 7 and the protrusion 8, as the active disk 401 rotates, the protrusion 8 pushes the sealing disk 402 gradually away from the active disk 401 until the protrusion 8 fits against the side of the sealing disk 402, and the sealing disk 402 stops moving in the valve body 1. The sealing disk 402 pushes the push piece 13 when moving, and the push piece 13 pushes the spring 12 to compress. As the area of ​​overlap between the first water through hole 5 and the second water through hole 6 becomes larger and larger, until the toggle handle 15 slides to the other end of the arc groove 14, the first water through hole 5 and the second water through hole 6 completely overlap, and the valve is fully opened.

[0029] When you want to close the valve, move the handle 15 from one end of the arc groove 14 to the other end. When the protrusion 8 is stuck in the inclined groove 7, the first water hole 5 and the second water hole 6 do not overlap at all. At this time, the water at the water inlet pipe 2 will press the sealing disk 402 against the active disk 401. At this time, with the help of water pressure and the elastic force of the spring 12, the sealing disk 402 and the active disk 401 are tightly fitted to achieve the closing effect of the valve.
