Description

Technical Field

[0001] This utility model relates to the field of pressure relief gate valve technology, specifically to a pressure relief gate valve for monitoring safety. Background Technology

[0002] Safety relief valves are key equipment for ensuring the pressure stability of industrial systems and are widely used in various pressure-bearing pipelines and containers. However, their traditional structure has gradually revealed many limitations in actual operation.

[0003] For example, the utility model with announcement number CN221374520U discloses a safety pressure relief gate valve, including a valve seat, a gate, and a valve stem. The gate is located inside the valve seat, and movable sleeves that cooperate with and seal the gate are provided on both sides of the valve seat. The gate is provided with a through hole within the inner diameter range of the movable sleeve. The through hole includes a flow section and two blocking sections. The diameter of the blocking section is larger than the diameter of the flow section. Two blocking elements are provided in the through hole. The blocking elements are located inside the gate and are used to block the connection between the blocking section and the flow section. The diameter of the blocking elements is smaller than the diameter of the blocking section. A movable cavity is provided in the middle of the bottom of the gate. This utility model provides blocking elements and a through hole in the gate. By relying on a driving element to drive the two connecting rods in the blocking elements to move, the through hole is kept open. In this way, when the gate valve is closed, fluid can flow from one side of the gate to the other side to achieve pressure relief.

[0004] In the process of developing this application, the following problems were found in the technology: The existing structure has obvious shortcomings in terms of ease of operation and efficiency. When the operator adjusts the rotary wheel with the push rod to control the opening and closing of the gate valve, the push rod is prone to positional deviation and wobbling during the rotation of the lower end of the rotary wheel due to the lack of a reliable positioning and limiting mechanism between the push rod and the rotary wheel. This not only requires repeated adjustment of the push rod angle to match the force point of the rotary wheel, increasing the complexity of the operation, but also makes the rotation adjustment process laborious due to unstable force, which greatly reduces the operator's comfort.

[0005] Therefore, a safety relief gate valve for monitoring is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a monitoring safety relief gate valve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pressure relief gate valve for monitoring safety includes a pressure relief gate valve body, the pressure relief gate valve body includes a rotary wheel and a screw, the rotary wheel is threadedly rotatably connected to the outer end of the screw, the lower surface of the rotary wheel has a groove, a drive component for effortless rotation of the rotary wheel is rotatably connected inside the groove, and a reset component is installed at the upper end of the rotary wheel.

[0009] Furthermore, the drive assembly includes multiple sets of push rods and connecting sleeves. The top ends of the multiple sets of push rods are rotatably connected to multiple sets of grooves inside the rotating wheel. The upper surface of the push rod has a sliding groove, and the connecting sleeve is slidably connected inside the sliding groove of the push rod. The lower surface of the rotating wheel has a positioning groove, and the position of the positioning groove of the rotating wheel is located on the moving path of the connecting sleeve. A spring is installed on the lower surface of the connecting sleeve, and the bottom end of the spring is installed at the bottom of the inner wall of the push rod sliding groove. The upper surface of the connecting sleeve abuts against the lower surface of the rotating wheel.

[0010] Furthermore, the push rod has a threaded hole at the end away from the rotating wheel, and a lead screw is connected to the internal thread of the threaded hole of the push rod. A pointed cone is installed at the end of the lead screw near the rotating wheel.

[0011] Furthermore, the reset assembly includes a spring telescopic rod, which is mounted on the upper surface of the rotating wheel. A positioning ring is mounted on the top end of the spring telescopic rod, and a connecting rod is mounted on the lower surface of the positioning ring. The positioning groove inside the rotating wheel is located on the moving path of the connecting rod.

[0012] Furthermore, the outer end of the push rod is fitted with a rubber sleeve, and the outer surface of the rubber sleeve is provided with anti-slip texture.

[0013] Furthermore, the outer surface of the push rod is provided with a groove, a magnetic block is installed inside the groove of the push rod, the inner wall of the rubber sleeve is provided with a sliding groove, an iron block is installed inside the sliding groove of the rubber sleeve, and the position of the groove of the push rod is located on the sliding path of the iron block.

[0014] Furthermore, the upper surface of the rubber sleeve abuts against the lower surface of the roller.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a push rod to rotate at the lower end of a rotating wheel. When the connecting sleeve is adjusted to the lower end of the positioning groove inside the rotating wheel, the spring uses its elasticity to push the connecting sleeve upward, inserting the top end of the connecting sleeve into the positioning groove of the rotating wheel. This restricts the rotation position of the push rod at the lower end of the rotating wheel. By pushing the push rod, the rotating wheel is accelerated to rotate at the outer end of the screw, thereby improving the comfort of the operator during the rotation and adjustment of the rotating wheel and shortening the time spent by the operator when opening or closing the pressure relief valve body. Therefore, the practicality of the device is improved.

[0017] 2. This utility model pushes the positioning ring to drive the connecting rod to be inserted into the positioning groove of the rotating wheel, and then the top of the connecting sleeve is inserted into the positioning groove of the rotating wheel. At this time, when the connecting rod slides, it pushes the connecting sleeve to reset and move into the slide groove of the push rod. This allows the operator to quickly rotate and reset the position of multiple sets of push rods, thereby shortening the time and labor spent by the operator in resetting the drive component, thus improving the practicality of the device.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 4As shown, a pressure relief gate valve for monitoring safety includes a pressure relief gate valve body 1. The pressure relief gate valve body 1 includes a rotary wheel 8 and a screw 3. The rotary wheel 8 is threadedly rotatably connected to the outer end of the screw 3. A groove is formed on the lower surface of the rotary wheel 8. A drive component 2 for effortless rotation of the rotary wheel 8 is rotatably connected inside the groove of the rotary wheel 8. A reset component 4 is installed at the upper end of the rotary wheel 8. Specifically, by pushing the drive component 2, the drive component 2 is vertically positioned and locked to the lower end of the rotary wheel 8. Then, by pushing the drive component 2, the rotary wheel 8 is rotated at the outer end of the screw 3. This improves the comfort of the operator during the rotation and adjustment of the rotary wheel 8 and shortens the time spent by the operator when opening or closing the pressure relief gate valve body 1, thus improving the practicality of the device. By pressing the reset component 4, the top end of the drive component 2 is moved, and the top end of the drive component 2 is quickly moved out of the interior of the rotary wheel 8, thereby shortening the time spent by the operator when resetting and adjusting the position of the drive component 2.

[0026] The drive assembly 2 includes multiple sets of push rods 201 and connecting sleeves 202. The top ends of the multiple sets of push rods 201 are rotatably connected to multiple sets of grooves in the rotating wheel 8. A groove is formed on the upper surface of the push rod 201, and the connecting sleeve 202 is slidably connected to the groove of the push rod 201. A positioning groove is formed on the lower surface of the rotating wheel 8, and the positioning groove is located on the moving path of the connecting sleeve 202. A spring 203 is installed on the lower surface of the connecting sleeve 202, and the bottom end of the spring 203 is installed at the bottom of the inner wall of the groove of the push rod 201. The upper surface of the connecting sleeve 202 abuts against the lower surface of the rotating wheel 8. Specifically, by pushing the push rod 201, the drive assembly moves the push rod 201... The lower end of the rotating wheel 8 rotates. When the connecting sleeve 202 is adjusted to the lower end of the positioning groove inside the rotating wheel 8, the spring 203 uses its own elasticity to push the connecting sleeve 202 upward, inserting the top end of the connecting sleeve 202 into the positioning groove inside the rotating wheel 8. This restricts the rotation position of the push rod 201 at the lower end of the rotating wheel 8. Then, by pushing the push rod 201, the rotating wheel 8 is accelerated to rotate at the outer end of the screw 3. This improves the comfort of the operator during the rotation and adjustment of the rotating wheel 8 and shortens the time spent by the operator when opening or closing the pressure relief valve body 1, thus improving the practicality of the device.

[0027] The push rod 201 has a threaded hole at the end away from the rotating wheel 8. A lead screw 9 is threaded inside the threaded hole of the push rod 201, and a pointed cone 10 is installed at the end of the lead screw 9 near the rotating wheel 8. Specifically, by rotating the lead screw 9, the length of the lead screw 9 inside the threaded hole of the push rod 201 is adjusted, so that the length of the extended push rod 201 can be adjusted simultaneously when the position of the lead screw 9 is adjusted. This allows the operator to adjust the overall length of the drive assembly 2 according to the installation position of the pressure relief valve body 1, making it easier for the operator to quickly push the drive assembly 2 to drive the rotating wheel 8 to rotate. By rotating the lead screw 9, the lead screw 9 is adjusted and moved to the outer end of the threaded hole of the push rod 201. At this time, pushing the lead screw 9 to drive the pointed cone 10 cleans the rust, debris or ice accumulated in the outer end of the screw 3, expanding the function of the drive assembly 2, thereby reducing the time spent by the operator when using the drive assembly 2 to drive the rotating wheel 8 to rotate, thus improving the practicality of the device.

[0028] The reset assembly 4 includes a spring telescopic rod 401, which is mounted on the upper surface of the rotating wheel 8. A positioning ring 402 is mounted on the top of the spring telescopic rod 401, and a connecting rod 403 is mounted on the lower surface of the positioning ring 402. The positioning groove inside the rotating wheel 8 is located on the moving path of the connecting rod 403. Specifically, by pushing the positioning ring 402, the connecting rod 403 is driven to insert into the positioning groove of the rotating wheel 8. Then, the top of the connecting sleeve 202 is inserted into the positioning groove of the rotating wheel 8. At this time, when the connecting rod 403 slides, it pushes the connecting sleeve 202 to reset and move into the groove of the push rod 201. This allows the operator to quickly rotate and reset the positions of multiple sets of push rods 201, thereby shortening the time and labor required by the operator in the reset drive assembly 2 process, thus improving the practicality of the device.

[0029] A rubber sleeve 5 is fitted onto the outer end of the push rod 201, and the outer surface of the rubber sleeve 5 is provided with anti-slip texture. Specifically, by fitting the rubber sleeve 5 onto the outer end of the push rod 201, the worker's hand comes into contact with the rubber sleeve 5 when pushing the push rod 201 to drive the rotating wheel 8 to rotate, thereby improving the worker's comfort when using the drive assembly 2 to drive the rotating wheel 8 to rotate. By providing anti-slip texture on the outer end of the rubber sleeve 5, the anti-slip texture increases the friction between the worker's hand and the outer surface of the rubber sleeve 5, preventing the worker's hand from slipping after prolonged contact with the rubber sleeve 5.

[0030] The outer surface of the push rod 201 has a groove, and a magnet 6 is installed inside the groove. The inner wall of the rubber sleeve 5 has a sliding groove, and an iron block 7 is installed inside the sliding groove. The groove of the push rod 201 is located on the sliding path of the iron block 7. Specifically, by installing the iron block 7 into the sliding groove of the rubber sleeve 5, when the rubber sleeve 5 is fitted to the outer end of the push rod 201, the iron block 7 is adjusted and moved to the upper end of the groove of the push rod 201, so that the iron block 7 slides and is attracted to the magnet 6 under the magnetic force. The upper surface of 6 restricts the movement of the rubber sleeve 5 at the outer end of the push rod 201 by the iron block 7 and the magnetic block 6, preventing the rubber sleeve 5 from slipping when it is fitted onto the outer end of the push rod 201, thus improving the stability of the rubber sleeve 5 during use. The rubber sleeve 5 has good deformation characteristics, allowing the operator to pull the iron block 7 by pulling the rubber sleeve 5, disconnecting the lower surface of the iron block 7 from the magnetic block 6, and preventing the rubber sleeve 5 from being unable to be disassembled and replaced when the iron block 7 is subsequently attracted to the outer surface of the magnetic block 6.

[0031] The upper surface of the rubber sleeve 5 abuts against the lower surface of the rotating wheel 8. Specifically, by keeping the position of the upper surface of the rubber sleeve 5 parallel to the position of the lower surface of the rotating wheel 8, when the operator pushes the push rod 201 and adjusts and moves the push rod 201 to the lower end of the rotating wheel 8, the upper surface of the rubber sleeve 5 abuts against the lower surface of the rotating wheel 8. At this time, the rubber sleeve 5 restricts the position of the push rod 201 at the lower end of the rotating wheel 8, so as to prevent the drive component 2 from rotating when idle, which would prevent the rotating wheel 8 from shielding and protecting the drive component 2.

[0032] In summary: By pushing the push rod 201 to rotate at the lower end of the rotating wheel 8, when the connecting sleeve 202 is adjusted to the lower end of the positioning groove inside the rotating wheel 8, the spring 203 uses its own elasticity to push the connecting sleeve 202 upward, inserting the top end of the connecting sleeve 202 into the positioning groove inside the rotating wheel 8. This restricts the rotation position of the push rod 201 at the lower end of the rotating wheel 8. Then, by pushing the push rod 201, the rotating wheel 8 is accelerated to rotate at the outer end of the screw 3, thereby improving the comfort of the operator during the rotation and adjustment of the rotating wheel 8 and shortening the time spent by the operator when opening or closing the pressure relief valve body 1.
