Description

Technical Field

[0001] This utility model relates to the field of valves, specifically to a sealing stop valve that is easy to open and close. Background Technology

[0002] A gate valve is a common type of valve, primarily used to open or close a fluid flow path. In existing technology, a gate valve generally consists of a valve body, a valve stem, and a valve core. The valve body has at least a fluid flow channel and an internal cavity. The valve core is movably installed within the valve body cavity. The valve stem is connected to the valve core; rotating the valve stem causes the valve core to rotate, thereby opening or closing the fluid flow channel on the valve body. However, in existing technology, the valve stem is typically a rotary wheel with a screw fixedly connected to it. The screw is threaded to the valve body, and the other end of the screw is connected to the valve core. Rotating the rotary wheel causes the screw to rotate, thus moving the screw relative to the valve body. This movement of the screw then moves the valve core, selectively opening or closing the fluid flow path. For example, Chinese utility model patent application number CN202520420878.4 discloses an easy-to-clean anti-clogging stop valve, belonging to the field of stop valve technology. This easy-to-clean anti-clogging stop valve includes a valve body with an installation port at the bottom that communicates with the interior. The valve body has an inlet channel and an outlet channel. A primary filter assembly is installed inside a filter tube to filter larger impurities, while a secondary filter assembly is installed inside the valve body to filter smaller dirt. The cooperation of the primary and secondary filter assemblies forms a dual filtration system, preventing the valve core and seat from becoming clogged. Simultaneously, the secondary filter assembly can quickly remove dirt from the filter screen through a threaded connection between the mounting ring and the installation port. The filter cartridge can be removed by removing the rotating plate. In this patent, a rotating wheel drives the valve stem to rotate; however, this structure is extremely time-consuming and inconvenient when opening or closing the fluid flow path. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient sealing and shut-off valve.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a convenient sealing and shut-off valve, comprising:

[0005] The valve body has a fluid flow channel and an installation channel, the axis of the fluid flow channel is perpendicular to the axis of the installation channel, and the fluid flow channel and the installation channel are connected.

[0006] The valve stem and the column valve core are movably installed in the installation channel of the valve body. The valve stem and the column valve core are connected. When the valve stem pivots, it drives the column valve core to move, thereby causing the column valve core to reciprocate in the installation channel of the valve body, thereby opening or cutting off the fluid flow channel of the valve body.

[0007] In some embodiments of this application, a connecting seat, a first support plate, and a second support plate are also included. The connecting seat includes a connecting disc. The first support plate and the second support plate are both fixedly connected to the connecting disc of the connecting seat, and there is a preset distance between the first support plate and the second support plate, thereby forming a pivoting space between the first support plate and the second support plate. One end of the valve stem is inserted into the pivoting space, and the valve stem, the first support plate, and the second support plate are fixedly connected by a pin, thereby enabling the valve stem to pivot relative to the first support plate and the second support plate.

[0009] In some embodiments of this application, a first connecting rod and a second connecting rod are also included. The connecting seat is provided with a movable through hole, which passes through the seat body of the connecting seat and the connecting disc. The second connecting rod and the valve core are fixedly installed together, and the second connecting rod is also fixedly connected to the first connecting rod. At least a portion of the first connecting rod passes through the movable through hole of the connecting seat. The first connecting rod and the valve stem are fixedly connected together, so that when the valve stem pivots, it drives the first connecting rod to move. The first connecting rod drives the second connecting rod to move, and the second connecting rod drives the valve core to move, thereby allowing the valve core to selectively open or close the fluid flow channel on the valve body during the movement.

[0010] In some embodiments of this application, a spring is also included, wherein the valve core has a receiving space, the spring is mounted in the receiving space, one end of the spring abuts against the inner wall of the receiving space of the valve core, and the other end of the spring abuts against the second connecting rod, at least a portion of the second connecting rod being inserted into the receiving space of the valve core, thereby fixing the second connecting rod to the valve core.

[0011] In some embodiments of this application, a pressure plate is also included, which is fixedly mounted on the valve body by bolts or screws. The pressure plate includes a pressing part that presses against the connecting disc of the connecting seat, so that when the connecting seat is fixedly mounted on the valve body, the pressing part of the pressure plate makes the connecting seat more stably mounted on the valve body.

[0012] In some embodiments of this application, a limiting member is also included. The valve body is provided with a limiting member mounting hole, and the limiting member is fixedly inserted into the limiting member mounting hole of the valve body, so that the limiting member is fixedly installed on the valve body and the limiting member is located on the path of the valve stem pivoting.

[0013] In some embodiments of this application, the fluid flow channel has a first opening and a second opening, both of which are in fluid communication with the fluid flow channel.

[0014] The beneficial effects of this application are: the gate valve provided by this application has a simple structure and is easy to assemble and disassemble. When opening or closing the fluid flow channel, the valve stem pivots relative to the valve body. During the pivoting process, the valve stem drives the valve core to move in the installation channel of the valve body, thereby allowing the valve core to leave or insert into the fluid flow channel. Compared with the structure of the existing wheel driving the screw to rotate, the gate valve of this application can open or close the fluid flow channel very quickly and is highly convenient.

[0023] Please refer to Figure 1-5 This application provides a convenient sealing shut-off valve (hereinafter referred to as "the shut-off valve"), which is mainly used to open or cut off the fluid flow path, thereby connecting or disconnecting the fluid flow. The shut-off valve provided by this application can quickly open or cut off the fluid flow path, and is highly convenient.

[0024] The shut-off valve includes:

[0025] The valve body 1 has a fluid flow channel 10 and an installation channel 11. The axis of the fluid flow channel 10 is perpendicular to the axis of the installation channel 11, and the fluid flow channel 10 and the installation channel 11 are connected.

[0026] The valve stem 3 and the column valve core 2 are movably installed in the mounting channel 11 of the valve body 1. The valve stem 3 and the column valve core 2 are connected. When the valve stem 3 pivots, it drives the column valve core 2 to move, thereby causing the column valve core 2 to reciprocate in the mounting channel 11 of the valve body 1, thus opening or cutting off the fluid flow channel 10 of the valve body 1. In this application, the column valve core 2 is approximately cylindrical in shape. Therefore, the cross-section of the mounting channel 11 of the valve body 1 is circular, and the column valve core 2 is adapted to the mounting channel 11 of the valve body 1. The pivoting motion of the valve core 3 mentioned here refers to the deflection motion of the valve core 3 relative to one or more fixed components. That is, one end of the valve core 3 is connected to the fixed component, and the other end of the valve core 3 undergoes circumferential deflection.

[0027] In some embodiments of this application, please refer to Figure 1-5 The shut-off valve further includes a connecting seat 13, a first support plate 4, and a second support plate 5. The connecting seat 13 includes a connecting disc 132. The first support plate 4 and the second support plate 5 are both fixedly connected to the connecting disc 132 of the connecting seat 13, and there is a preset distance between the first support plate 4 and the second support plate 5, thereby forming a pivoting space 6 between the first support plate 4 and the second support plate 5. One end of the valve stem 3 is inserted into the pivoting space 6, and the valve stem 3, the first support plate 4, and the second support plate 5 are fixedly connected by a pin 7, so that the valve stem 3 can pivot relative to the first support plate 4 and the second support plate 5. The connecting seat 13 is detachably fixedly installed in the mounting channel 11 of the valve body 1. In this application, the fixed connection method between the first support plate 4, the second support plate 5, and the connecting disc 132 includes welding, bolt connection, screw connection, or snap-fit. Preferably, in this application, the first support plate 4, the second support plate 5, and the connecting disc 132 are fixedly connected together by welding. In this application, the installation channel 11 of the valve body 1 has a preset length, and when the connecting seat 13 is installed into the installation channel 11, the connecting seat 13 can only occupy a part of the installation channel 11.

[0028] In some embodiments of this application, please refer to Figure 1-5 The connecting seat 13 also includes a seat body 131, which is fixedly connected to the connecting disc 132. An external thread 14 is provided on the circumferential outer wall of the seat body 131.

The seat body 131 of the connecting seat 13 and the mounting channel 11 of the valve body 1 are detachably connected together by means of internal and external thread connection, so that the connecting seat 13 can be fixedly installed on the valve body 1.

[0029] In some embodiments of this application, please refer to Figure 1-5 The shut-off valve further includes a first connecting rod 15 and a second connecting rod 16. A movable through hole 130 is provided on the connecting seat 13, which passes through the seat body 131 and the connecting disc 132 of the connecting seat 13. The second connecting rod 16 is fixedly installed together with the valve core 2, and the second connecting rod 16 is also fixedly connected to the first connecting rod 15. At least a portion of the first connecting rod 15 passes through the movable through hole 130 of the connecting seat 13. The first connecting rod 15 is fixedly connected to the valve stem 3, so that when the valve stem 3 pivots, it drives the first connecting rod 15 to move, the first connecting rod 15 drives the second connecting rod 16 to move, and the second connecting rod 16 drives the valve core 2 to move. This allows the valve core 2 to selectively open or close the fluid flow channel 10 on the valve body 1 during its movement. In this application, the fixed connection method between the first connecting rod 15 and the second connecting rod 16 includes welding, bolting, screwing, snap-fitting, or shaft-hole mating connection. Preferably, a insertion hole is provided on the second connecting rod 16, and the first connecting rod 15 is inserted into the insertion hole, with the first connecting rod 15 and the insertion hole being interference-fitted together, thereby fixing the first connecting rod 15 and the second connecting rod 16 together. The fixed connection between the second connecting rod 16 and the valve core 2 is also through a shaft-hole fit connection. For example, a insertion hole is provided on the valve core, and at least a portion of the second connecting rod 16 is inserted into the insertion hole of the valve core 2.

[0030] In some embodiments of this application, please refer to Figure 1-5 The shut-off valve also includes a spring 17. The valve core 2 has a receiving space 20, and the spring 17 is installed in the receiving space 20. One end of the spring 17 abuts against the inner wall of the receiving space 20 of the valve core 2, and the other end of the spring 17 abuts against the second connecting rod 16. At least a portion of the second connecting rod 16 is inserted into the receiving space 20 of the valve core 2, thereby fixing the second connecting rod 16 to the valve core 2. In this application, one end of the spring 17 is actually fixedly connected to the inner wall of the receiving space 20 of the valve core 2, and the other end of the spring 17 is fixedly connected to the second connecting rod 16. The second connecting rod 16 and the valve core 2 are fixedly connected together. If the second connecting rod 16 falls off the valve core 2 during use, the spring 17 will keep the second connecting rod 16 and the valve core 2 connected together.

[0031] In some embodiments of this application, please refer to Figure 1-5The shut-off valve also includes a pressure plate 8, which is fixedly mounted on the valve body 1 by bolts or screws. The pressure plate 8 includes a pressing part 81, which presses against the connecting disc 132 of the connecting seat 13. This allows the connecting seat 13 to be more stably mounted on the valve body 1 when it is fixedly mounted on the valve body 1 by the pressing part 81 of the pressure plate 8.

[0032] In some embodiments of this application, please refer to Figure 1-5 The shut-off valve also includes a limiting member 9. A limiting member mounting hole 12 is provided on the valve body 1, and the limiting member 9 is fixedly inserted into the limiting member mounting hole 12 of the valve body 1, thereby fixing the limiting member 9 onto the valve body 1. The limiting member 9 is located on the pivoting path of the valve stem 3. Thus, when the valve stem 3 pivots to a preset position and encounters the limiting member 9, the limiting member 9 prevents the valve stem 3 from pivoting further. In this application, the limiting member 9 is a bolt or screw, and correspondingly, the limiting member mounting hole 12 provided on the valve body 1 is a bolt hole or screw hole, so that the limiting member 9 can be detachably and fixedly connected to the limiting member mounting hole 12.

[0033] In some embodiments of this application, please refer to Figure 1-5 The fluid flow channel 10 has a first opening 101 and a second opening 102, both of which are in fluid communication with the fluid flow channel 10. In this application, the first opening 101 and the second opening 102 are used for fluid inflow or outflow. For example, if the first opening 101 is used for fluid inflow, then the second opening 102 is used for fluid outflow.

[0034] The shut-off valve provided in this application has a simple structure and is easy to assemble and disassemble. When opening or closing the fluid flow channel, the valve stem pivots relative to the valve body. During the pivoting process, the valve stem drives the valve core to move in the installation channel of the valve body, thereby allowing the valve core to leave or insert into the fluid flow channel. Compared with the structure of the existing wheel driving the screw to rotate, the shut-off valve of this application can open or close the fluid flow channel very quickly, which is very convenient.
