Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a plunger type cut-off valve structure. Background Art

[0002] The plunger cut-off valve is a valve that quickly opens or closes the fluid in the pipeline through the up and down linear motion of the plunger. It is mainly used in occasions where the flow of fluid needs to be quickly cut off or connected, such as emergency shutdown systems, fire protection systems, chemical processing equipment, etc.

[0003] However, in the current existing technology, some plunger-type cut-off valves still rely on a single internal plunger to perform fluid closing work. After long-term use, the fluid may wear the internal seals, resulting in the fluid being unable to accurately complete the sealing work. Therefore, there are certain limitations. At the same time, the driving structure of some plunger-type cut-off valves is installed by multiple bolts. When the internal parts need to be inspected or replaced, the operation is cumbersome, so a solution is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art: in the current prior art, some plunger-type cut-off valves still use a single internal plunger to close the fluid. After long-term use, the fluid wears the internal seal, resulting in the inability of the fluid to accurately complete the sealing work. Therefore, there are certain limitations. At the same time, the driving structure of some plunger-type cut-off valves is installed by multiple bolts. When it is necessary to inspect or replace the internal parts, the operation is relatively cumbersome.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a plunger type cut-off valve structure, comprising: a base and a mounting member; a valve body, fixedly mounted on the top surface of the base; and further comprising:

[0006] Two notches are provided at symmetrical positions of the valve body away from the base surface, a spring is fixedly installed on the inner wall of the two notches, a clamp is fixedly installed on one end surface of the two springs, a round shaft is fixedly installed on one side surface of the two clamps, one end of the two round shafts is movably embedded in the inner wall of the valve body, and a sealing gasket is fixedly installed on the inner wall of the valve body;

[0007] Two mounting blocks are fixedly mounted at symmetrical positions on one side surface of the mounting piece, and one side surface of the two mounting blocks is slidably connected to the inner wall of the notch.

[0008] Preferably, a triangular block is fixedly mounted on one side surface of the two mounting blocks, and the two triangular blocks are slidably connected to the outer surface of the clamping block.

[0009] The technical effect of adopting the above further solution is: the triangular block on the surface of the installation block is engaged with the clamping block, thereby completing the positioning work of the installation part.

[0010] Preferably, a partition is fixedly mounted on the inner wall of the valve body, and two through holes are formed on the surface of the partition.

[0011] The technical effect of adopting the above further solution is: the fluid is blocked by the partition inside the valve body, and the fluid flows through the through holes on the surface.

[0012] Preferably, a limit ring is fixedly installed on the inner wall of the valve body, and a second spring is fixedly installed on the mounting piece close to the inner wall of the valve body.

[0013] The technical effect of adopting the above further solution is: the valve body provides supporting force to the limit ring, and the mounting part positions the internal spring 2 at the same time.

[0014] Preferably, a moving part is fixedly mounted on one end surface of the spring 2, and an outer surface of the moving part is slidably embedded in the inner wall of the limiting ring.

[0015] The technical effect of adopting the above further solution is: the moving part connected to the surface is provided with a reset capability through two pairs of springs, and at the same time the limit ring limits the moving part to prevent tilting during movement.

[0016] Preferably, a plunger body is fixedly mounted at a symmetrical position on one side surface of the moving member, and the outer surfaces of the two plunger bodies are movably engaged with the inside of the through hole.

[0017] The technical effect of adopting the above further solution is that when the moving part moves, the plunger body of the driving surface is embedded in the interior of the through hole, thereby completing the closing work.

[0018] Preferably, a sealing gasket 2 is fixedly mounted on one end surface of the two plunger bodies, and one side surface of the two sealing gaskets 2 is movably connected to the surface of the partition.

[0019] The technical effect of adopting the above further solution is: the sealing work is strengthened by connecting the sealing gasket 2 on the surface of the plunger body to the partition.

[0020] Preferably, a threaded rotating member is threadedly embedded in the surface of the mounting member, and one end surface of the threaded rotating member is movably connected to the surface of the moving member.

[0021] The technical effect of adopting the above further solution is: when the threaded rotating part on the surface of the rotating mounting part is rotated, the threaded rotating part contacts the moving part, thereby driving the moving part to move.

[0022] Compared with the prior art, the advantages and positive effects of the utility model are:

[0023] 1. In the utility model, when in use, the base provides supporting force to the valve body, and when the mounting block on the surface of the mounting piece is embedded in the inside of the notch, the triangular block on the surface is slidably connected with the clamping block, and at the same time, the two ends of the spring are respectively connected to the surface of the notch and the clamping block, so that the clamping block has the ability to move and reset. When the clamping block and the triangular block are misaligned, the triangular block is engaged, and when the circular shaft is pulled, the clamping block on the surface is driven to move, thereby disassembling the mounting piece as a whole, so as to quickly inspect and maintain the internal parts, and the operation is simple.

[0024] 2. In the utility model, the two ends of spring 2 are respectively connected to the inner walls of the moving part and the mounting part. When the threaded rotating part on the surface of the rotating mounting part is rotated, the threaded rotating part contacts the moving part, driving the moving part to move on the inner wall of the limit ring. At the same time, one end of the moving part is movably embedded in the inner wall of the sealing gasket 1 to perform sealing work, and at the same time drives the plunger body on the surface to be embedded in the inside of the through hole, thereby completing the closing work. At the same time, the sealing gasket 2 on the surface of the plunger body is connected to the partition to strengthen the sealing work. By providing two plunger bodies, it is prevented that a single part cannot accurately control the fluid due to wear, thereby improving the accuracy performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, when in use, the base 1 provides a supporting force for the valve body 2, and when the mounting block 301 on the surface of the mounting member 3 is embedded in the groove 202, the triangular block 302 on the surface is slidably connected with the clamping block 2022, and at the same time, the two ends of the spring 1 2021 are respectively connected to the surface of the groove 202 and the clamping block 2022, so that the clamping block 2022 has the ability to move and reset. When the clamping block 2022 is misaligned with the triangular block 302, the triangular block 302 is engaged, and when the circular shaft 2023 is pulled, the clamping block 2022 on the surface is driven to move, thereby disassembling the mounting member 3 as a whole, so as to quickly inspect and maintain the internal parts, and the operation is simple.

[0036] In the second embodiment, a triangular block 302 is fixedly installed on one side surface of the two mounting blocks 301, and the two triangular blocks 302 are slidably connected with the outer surface of the clamping block 2022.
