Description

Technical Field

[0001] The present invention relates to the technical field of fire hydrants, and particularly to an intelligent monitoring device for fire hydrants and an intelligent fire hydrant. Background Art

[0002] A fire hydrant is a fixed fire-fighting tool mainly used to control combustibles, isolate combustion-supporting substances, and eliminate fire sources. Fire hydrants are mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire fighting, and can also be directly connected to a water hose and a water gun to discharge water for fire fighting. It is one of the important fire-fighting facilities for extinguishing fires. However, since fire hydrants are standing by the roadside, they are often easily damaged by passing vehicles, resulting in the breakage of the fire hydrant housing, and at the same time, the valve stem inside the fire hydrant housing is also broken. At this time, the valve flap will lose the support force of the valve stem on it, causing the valve flap to disengage and fall off, and water will gush out from the fire hydrant. Although there are also some intelligent fire hydrants with intelligent monitoring devices on the existing market, which can monitor the status of the intelligent fire hydrant in real time and generate an alarm, so as to ensure that maintenance personnel can go there in time for maintenance. However, since most of the existing intelligent monitoring devices only have a monitoring effect and do not have a water-blocking and isolating effect, they may be damaged after being impacted, and it also takes a certain amount of time for the maintenance personnel to arrive. Therefore, a large amount of water resources will be wasted during this period. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent monitoring device for a fire hydrant and an intelligent fire hydrant with a practical and reliable overall structure, which can better ensure the integrity and normal use of the intelligent monitoring device of the fire hydrant after being impacted, and has both a monitoring function and a water-blocking and sealing effect, effectively avoiding a large amount of water resource waste after being impacted.

Elastic connection assemblies are used for elastic connection between the four corners of the upper connection seat and the four corners of the lower connection seat. Isosceles trapezoidal embedding blocks are fixedly provided at the four sides of the lower end face of the upper connection seat, and embedding grooves adapted to the embedding blocks are provided at the four sides of the upper end face of the lower connection seat. The embedding blocks and the embedding grooves are fitted and engaged with each other.

[0006] Furthermore, the elastic connection assembly includes a connection bolt, a connection nut, and a connection spring. Upper through holes are provided at the four corners of the upper connection seat, and lower through holes are provided at the four corners of the lower connection seat. The connection bolt sequentially passes through the lower through hole and the upper through hole and is threadedly connected to the connection nut. An annular stopper is fixedly provided in the lower through hole. The connection spring is sleeved on the connection bolt and is located in the lower through hole. One end of the connection spring abuts against the connection bolt and the other end abuts against the annular stopper.

The placement plate is fixedly connected to the upper housing. The upper end face of the placement plate is provided with a rolling concave surface that is low in the center and high around the periphery. A plurality of flow ports are provided around the rolling concave surface on the placement plate. The housing is fixedly installed on the upper end of the placement plate and covers the rolling concave surface.

The lower end of the trigger rope passes through the sealing sleeve and extends downward into the water sealing assembly and is fixedly connected to the trigger block, and the trigger block is used to trigger the water sealing assembly to act.

[0008] Further, the water sealing assembly includes a water sealing plate, a connecting plate, a guide rod, a limiting ball, and a water sealing spring. The connecting plate is arranged at the lower end of the lower housing. The lower end of the guide rod is fixedly arranged at the upper end of the connecting plate, and the upper end of the guide rod extends upward to the lower end of the placing plate. A plurality of communication ports are arranged around the guide rod on the connecting plate. The water sealing plate is provided with a guide hole adapted to the guide rod, and the water sealing plate is sleeved on the guide rod through the guide hole. The lower end surface of the water sealing plate is in the shape of a frustum of a cone with a wider upper part and a narrower lower part. A limiting sleeve extending downward is fixedly arranged at the center of the lower end of the water sealing plate. An O-ring is installed on the inner surface of the guide hole of the water sealing plate. The water sealing spring is sleeved on the guide rod and abuts between the water sealing plate and the connecting plate. A trigger channel that opens upward and is adapted to the trigger block is arranged in the guide rod. A plurality of limiting holes communicating with the trigger channel are arranged on the outer peripheral surface of the guide rod along its circumferential direction. The outer diameter of the limiting ball is consistent with the inner diameter of the limiting hole and the inner diameter of the trigger channel. An annular limiting block adapted to the limiting ball is fixedly arranged on the outer edge of the inner surface of the limiting hole on the guide rod.

The limiting balls can partially penetrate out of the annular limiting block and play a role in limiting the upward movement of the water sealing plate. The trigger block is suspended in the trigger channel through a trigger rope and is used to seal the inner openings of the plurality of limiting holes. The bottom end of the trigger block is in a sharp angle shape. When the water sealing plate is in the limiting position limited by the limiting balls, a flow channel is formed between the inner surface of the lower cavity of the lower housing and the outer peripheral surface of the water sealing plate. When the trigger ball rolls, it can drive the trigger block to move upward through the trigger rope to release the limitation on the limiting balls.

The battery module, the communication module, and the pressure sensor are all electrically connected to the core processor. The pressure sensor is used to monitor the pressure signal and transmit the pressure signal to the core processor. The communication module is used to modulate the alarm information of the core processor and transmit it to the cloud background.

[0011] Further, the upper housing is fixedly connected to the valve body through a break-off mechanism. The break-off mechanism includes an annular break-off pressing plate, an elastic pad, and a bolt assembly.

The pressing blocks are fixedly pressed against the upper end of the lower flange of the valve body. An elastic pad is also arranged between the lower flange and the upper flange. At the upper end of the connection between the pressing block and the annular break-off pressing plate, a strip-shaped break-off seam is provided.

[0013] The intelligent fire hydrant includes a hydrant body, a valve body, an elbow, and the fire hydrant intelligent monitoring device of any one of the above. The hydrant body, the valve body, the fire hydrant intelligent monitoring device, and the elbow are fixedly connected in sequence from top to bottom.

[0014] As can be seen from the above description, the fire hydrant intelligent monitoring device and the intelligent fire hydrant provided by the present invention have the following beneficial effects: During use, when the hydrant body or the valve body of the intelligent fire hydrant is impacted in a corresponding direction, through the setting of the flexible connection and sealing mechanism, under the action of the impact external force, the upper housing can swing and tilt at a certain angle relative to the lower housing, thereby reducing the impact force directly transmitted to the lower housing during the impact process, effectively avoiding the overall rigid damage of the fire hydrant intelligent monitoring device, and better ensuring its overall integrity and normal use; Through the setting of the gravity-triggered water sealing mechanism, during the impact process, the gravity-triggered component arranged in the upper housing can swing and tilt together with the upper housing, thereby triggering the water sealing component arranged in the lower housing to act and seal the water sealing port to achieve water sealing, thus having a good water sealing and blocking effect. Even if the valve flap in the intelligent fire hydrant is loosened or fallen off due to impact, it can avoid causing a large amount of water resource waste; Through the setting of the monitoring component, real-time monitoring can be realized. When the intelligent fire hydrant is impacted and the gravity-triggered water sealing mechanism triggers water sealing, it can timely notify the corresponding maintenance personnel to go for maintenance in time.

Detailed implementation mode

[0026] The present invention will be further described below through specific implementation modes.

[0027] As Figures 1 to 9As shown in the figure, the intelligent fire hydrant monitoring device 11 of the present invention includes an upper housing 2 for connecting with a valve body 13, a lower housing 3 for connecting with an elbow 14, a gravity-triggered water sealing mechanism 4, and a monitoring component 5. An upper cavity 21 penetrating through the upper and lower ends is provided in the upper housing 2, and a lower cavity 31 penetrating through the upper and lower ends is provided in the lower housing 3. The lower end of the upper housing 2 and the upper end of the lower housing 3 are flexibly sealed and connected by a flexible connection sealing mechanism 6, allowing the upper housing 2 to swing and tilt relative to the lower housing 3 in any direction around. The gravity-triggered water sealing mechanism 4 includes a gravity-triggered component 41, a water sealing component 42, and an annular limiting plate 43. The gravity-triggered component 41 is arranged in the upper cavity 21 of the upper housing 2, the annular limiting plate 43 is fixedly arranged on the inner surface of the lower cavity 31 of the lower housing 3, a water sealing port 431 is provided in the annular limiting plate 43, and the water sealing component 42 is arranged in the lower cavity 31 of the lower housing 3 and is located below the annular limiting plate 43. When the gravity-triggered component 41 swings and tilts along with the upper housing 2, the water sealing component 42 can be triggered to act and seal the water sealing port 431 to achieve water sealing. The monitoring component 5 is used to monitor whether the gravity-triggered water sealing mechanism 4 triggers water sealing.

[0028] During use, when the body 12 or valve body 13 of the intelligent fire hydrant is impacted in a corresponding direction, due to the setting of the flexible connection sealing mechanism 6, under the action of the impact external force, the upper housing 2 can swing and tilt at a certain angle relative to the lower housing 3, thereby reducing the impact force directly transmitted to the lower housing 3 during the impact, effectively avoiding the overall rigid damage of the fire hydrant intelligent monitoring device 11, and better ensuring its overall integrity and normal use. Due to the setting of the gravity-triggered water sealing mechanism 4, during the impact, the gravity-triggered component 41 arranged in the upper housing 2 can swing and tilt together with the upper housing 2, thereby triggering the water sealing component 42 arranged in the lower housing 3 to act and seal the water sealing port 431 to achieve water sealing, thus having a good water sealing and blocking effect. Even if the valve flap in the intelligent fire hydrant is loosened or detached due to impact, a large amount of water resource waste can be avoided. Due to the setting of the monitoring component 5, real-time monitoring can be realized. When the intelligent fire hydrant is impacted and the gravity-triggered water sealing mechanism 4 triggers water sealing, corresponding maintenance personnel can be notified in time to go for maintenance.

[0029] The flexible connection and sealing mechanism 6 includes an upper connection seat 61, a lower connection seat 62, an elastic sealing inner sleeve 63, a first sealing gasket, and an elastic connection assembly 64. The lower end of the upper housing 2 is fixedly provided with the upper connection seat 61, and the upper end of the lower housing 3 is fixedly provided with the lower connection seat 62. An upper connection cavity 611 communicating with the upper cavity 21 is provided in the upper connection seat 61, and a lower connection cavity 621 communicating with the lower cavity 31 is provided in the lower connection seat 62. The first sealing gasket is arranged between the end faces of the upper connection seat 61 and the lower connection seat 62. The elastic sealing inner sleeve 63 is arranged between the inner surfaces of the upper connection cavity 611 and the lower connection cavity 621, and its upper and lower ends are respectively fixedly connected to the upper connection seat 61 and the lower connection seat 62. Preferably, the elastic sealing inner sleeve 63 can be made of elastic rubber to ensure the sealing performance during the flexible sealing connection between the upper connection seat 61 and the lower connection seat 62. The four corners of the upper connection seat 61 and the four corners of the lower connection seat 62 are elastically connected through the elastic connection assembly 64. Isosceles trapezoidal blocks 612 are fixedly provided at the four edges of the lower end face of the upper connection seat 61, and grooves 622 adapted to the blocks 612 are provided at the four edges of the upper end face of the lower connection seat 62. The blocks 612 are fitted with the grooves 622 in an embedded manner, that is, the outer bottom surface of the block 612 is in contact with the inner bottom surface of the groove 622. Since the two side end faces of the block 612 are inclined surfaces, when the block 612 is fitted with the groove 622, under the action of an impact external force, the block 612 and the groove 622 will not be stuck, and the upper connection seat 61 and the lower connection seat 62 can swing relative to each other. In addition, preferably, the included angle between the lower bottom and the waist of the block 612 is 70-75 degrees to ensure the swinging effect of the upper connection seat 61 relative to the lower connection seat 62 in all directions around. The elastic connection assembly 64 includes a connection bolt 641, a connection nut 642, and a connection spring 643. Upper through holes 613 are provided at the four corners of the upper connection seat 61, and lower through holes 623 are provided at the four corners of the lower connection seat 62. The connection bolt 641 passes through the lower through hole 623 and the upper through hole 613 in sequence and is threadedly connected to the connection nut 642. An annular stop block 624 is fixedly provided in the lower through hole 623. The connection spring 643 is sleeved on the connection bolt 641 and is located in the lower through hole 623. One end of the connection spring 643 abuts against the connection bolt 641 and the other end abuts against the annular stop block 624. The connection spring 643 is a compression spring. Thus, the flexible sealing connection between the upper connection seat 61 and the lower connection seat 62 can be realized. When the body 12 or the valve body 13 of the intelligent fire hydrant is impacted in a corresponding direction, under the action of the impact external force, the upper housing 2 can swing and tilt adaptively relative to the lower housing 3 by a certain angle.And compress the connecting spring 643 at the corresponding position, so that the connecting spring 643 undergoes elastic deformation, and a certain degree of swing separation appears between the upper connecting seat 61 and the lower connecting seat 62, thereby reducing the impact force directly transmitted to the lower housing 3 during the impact, and effectively avoiding the overall rigid damage of the intelligent fire hydrant monitoring device 11, better ensuring its overall integrity and normal use. At the same time, when the impact external force disappears, under the action of the elastic force of the connecting spring 643, and in cooperation with the fitting between the embedding block 612 and the embedding groove 622, the upper housing 2 can be accurately reset.

[0030] The gravity trigger assembly 41 includes a trigger ball 411, a trigger rope 412, a trigger block 413, a placement plate 414 and a housing 415. The placement plate 414 is fixedly connected to the upper housing 2. The upper end surface of the placement plate 414 is provided with a rolling concave surface 4141 that is low in the center and high around. Preferably, the inclination angle of the rolling concave surface 4141 relative to the upper end surface of the placement plate 414 is 1-3 degrees. A plurality of circulation ports 4142 are provided around the rolling concave surface 4141 on the placement plate 414. Preferably, the number of the circulation ports 4142 is 4-6. The housing 415 is fixedly installed on the upper end of the placement plate 414 and covers the rolling concave surface 4141. A rolling cavity 4151 is formed by surrounding between the housing 415 and the rolling concave surface 4141. The trigger ball 411 is rollably arranged in the rolling cavity 4151. Correspondingly, the trigger ball 411 is a steel ball and has a certain weight. Under normal circumstances, the trigger ball 411 can be stably located at the center of the rolling concave surface 4141. A perforation 4143 is provided at the center of the rolling concave surface 4141. A sealing sleeve 4144 adapted to the trigger rope 412 is fixedly provided on the inner peripheral surface of the perforation 4143. Preferably, the sealing sleeve 4144 is made of rubber material to ensure the sealing performance. The upper end of the trigger rope 412 is fixedly connected to the trigger ball 411. The lower end of the trigger rope 412 passes through the sealing sleeve 4144 and extends downward into the water sealing assembly 42 and is fixedly connected to the trigger block 413. Preferably, the trigger rope 412 is a soft rope. The trigger block 413 is used to trigger the water sealing assembly 42 to act. Preferably, the trigger block 413 is in a cylindrical shape. The trigger block 413 is a steel block and has a certain weight and is less than the weight of the trigger ball 411.

[0031] The water sealing assembly 42 includes a water sealing plate 421, a connecting plate 422, a guide rod 423, a limiting ball 424 and a water sealing spring 425. The connecting plate 422 is arranged at the lower end of the lower housing 3. The lower end of the guide rod 423 is fixedly arranged at the upper end of the connecting plate 422. The upper end of the guide rod 423 extends upward to the lower end of the placing plate 414. A plurality of communication ports 4221 are arranged around the guide rod 423 on the connecting plate 422. Preferably, the number of the communication ports 4221 is 4 - 6. A guide hole 4211 adapted to the guide rod 423 is arranged on the water sealing plate 421. The water sealing plate 421 is sleeved on the guide rod 423 through the guide hole 4211, thereby playing a good guiding role in the up and down movement of the water sealing plate 421. Preferably, the guide rod 423 is in a cylindrical shape or a cuboid shape. The lower end surface of the water sealing plate 421 is in a frustum shape with a wider upper part and a narrower lower part. Thus, it can also play a certain guiding role in the flow of water. A limiting sleeve 4212 extending downward is fixedly arranged at the center of the lower end of the water sealing plate 421. An O-ring 4213 is installed on the inner surface of the guide hole 4211 of the water sealing plate 421, thereby improving the sealing performance of the connection between the water sealing plate 421 and the guide rod 423. The water sealing spring 425 is sleeved on the guide rod 423 and abuts between the water sealing plate 421 and the connecting plate 422. The water sealing spring 425 is a compression spring. A trigger channel 4231 which is open upward and adapted to the trigger block 413 is arranged in the guide rod 423. A plurality of limiting holes 4232 communicating with the trigger channel 4231 are arranged on the outer peripheral surface of the guide rod 423 along the circumferential direction. Preferably, the number of the limiting holes 4232 is 2 - 4. The outer diameter of the limiting ball 424 is consistent with the inner diameter of the limiting hole 4232 and the inner diameter of the trigger channel 4231. An annular limiting block 4233 adapted to the limiting ball 424 is fixedly arranged on the outer edge of the inner surface of the limiting hole 4232 on the guide rod 423. The movable limiting balls 424 are arranged in a plurality of the limiting holes 4232. Preferably, the limiting balls 424 are steel balls. The limiting balls 424 can partially penetrate out of the annular limiting block 4233 and play a limiting role in the upward movement of the water sealing plate 421. The trigger block 413 is suspended in the trigger channel 4231 through the trigger rope 412 and is used to seal the inner openings of a plurality of the limiting holes 4232. At this time, the limiting balls 424 in the limiting holes 4232 will be restricted, and the stability during limiting is ensured, so that the water sealing plate 421 is in a stable limiting position. The bottom end of the trigger block 413 is in a sharp angle shape. In addition, through the arrangement of the limiting sleeve 4212, a corresponding limiting role can be played in the downward movement of the water sealing plate 421 to avoid excessive downward pressure when the water sealing plate 421 is reset downward. At the same time, when the water sealing plate 421 is in the water sealing position,The limiting sleeve 4212 also seals the outer opening of the limiting hole 4232 to better restrict the free movement of the plurality of limiting balls 424 relative to each other, so as to prevent any of the limiting balls 424 from directly falling into the trigger channel 4231. When the water sealing plate 421 is in the limiting position limited by the limiting balls 424, a flow channel 9 is formed between the inner surface of the lower cavity 31 of the lower housing 3 and the outer peripheral surface of the water sealing plate 421 to ensure normal water discharge during fire fighting. Correspondingly, the peripheral surfaces of the bottom of the lower housing 3 all protrude outward to better form the flow channel 9. When the trigger ball 411 rolls, it can drive the trigger block 413 to move upward through the trigger rope 412 to release the limitation on the limiting balls 424. At this time, the water sealing plate 421 can drive the limiting balls 424 to retract inward under the drive of the water sealing spring 425, so that the water sealing plate 421 continues to move upward and switches to the water sealing position and seals the water sealing port 431.,

[0032] During use, when the body 12 or valve body 13 of the intelligent fire hydrant is impacted in a corresponding direction, when the gravity trigger assembly 41 in the upper housing 2 swings and tilts together with the upper housing 2, the placement plate 414 is tilted in the corresponding direction. At this time, the trigger ball 411 in the rolling cavity 4151 can roll or slide along the rolling concave surface 4141 towards the lower side of the tilt due to its own weight. Through the linkage of the trigger rope 412, the trigger block 413 can be driven to move upward to release the limitation on the limiting balls 424. At this time, the water sealing plate 421 can drive the limiting balls 424 to retract inward under the drive of the water sealing spring 425, so that the water sealing plate 421 continues to move upward and switches to the water sealing position and seals the water sealing port 431, thus achieving the water sealing and blocking effect. Moreover, it does not require power supply, uses gravity and adopts a mechanical structure to achieve automatic water sealing and blocking, solves the failure problem caused by electronic system faults, and has a fast trigger response and accurate action.

[0033] Preferably, the inner surface of the water sealing port 431 of the annular limiting plate 43 is in the shape of a round table surface that is narrower at the top and wider at the bottom. The upper end of the water sealing plate 421 is fixedly provided with a sealing block 4214 that is adapted to the water sealing port 431 and can be embedded in the water sealing port 431. The upper end surface of the water sealing plate 421 and the outer peripheral surface of the sealing block 4214 are both fixedly covered with a second sealing gasket 4215. In this way, it is beneficial to further improve the water sealing effect between the water sealing plate 421 and the annular limiting plate 43, and it is more difficult for water seepage to occur. Preferably, the second sealing gasket 4215 can be made of rubber or silica gel materials.

[0034] The monitoring component 5 includes a monitoring housing 51, a core processor, a battery module, a communication module, and a pressure sensor 52. The monitoring housing 51 is fixedly installed on the outer side of the lower housing 3. In addition, a protective housing may be provided on the outer side of the monitoring housing 51 to further protect the monitoring component 5. The core processor, the battery module, and the communication module are all arranged inside the monitoring housing 51. The pressure sensor 52 is installed at the bottom end of the annular limiting plate 43. Correspondingly, a first installation groove for installing the pressure sensor 52 is provided at the bottom end of the annular limiting plate 43. An elastic pressure sensing plate 53 that cooperates with the pressure sensor 52 is elastically connected to the upper end of the water sealing plate 421. Correspondingly, a second installation groove for installing the pressure sensing plate 53 is provided at the upper end of the water sealing plate 421. The pressure sensing plate 53 and the water sealing plate 421 are elastically connected by an elastic member. The elastic member uses a compression spring. The battery module, the communication module, and the pressure sensor 52 are all electrically connected to the core processor. The pressure sensor 52 is used to monitor the pressure signal and transmit the pressure signal to the core processor. The communication module is used to modulate the alarm information of the core processor and transmit it to the cloud background. During use, when the intelligent fire hydrant is accidentally impacted and the water sealing plate 421 moves upward to seal the water sealing port 431 of the annular limiting plate 43, at this time, the pressure sensing plate 53 contacts the pressure sensor 52 and compresses the elastic member. The pressure sensor 52 generates a pressure signal and transmits the pressure signal to the core processor. Then, the communication module can modulate the alarm information of the core processor and transmit it to the cloud background to achieve monitoring and notify the corresponding maintenance personnel to go for maintenance in time. When resetting the gravity-triggered water sealing mechanism 4, a corresponding tool can be used to press down the water sealing plate 421 until the water sealing plate 421 is located below the limiting hole 4232. At this time, the water sealing plate 421 and the limiting sleeve 4212 no longer block the outer opening of the limiting hole 4232. Under the action of its own weight of the trigger block 413, and by setting the bottom end of the trigger block 413 to be pointed, during the process of the trigger block 413 moving downward due to its own weight, it can automatically push the limiting ball 424 in the limiting hole 4232 to move outward and partially penetrate the annular limiting block 4233. Then, the water sealing plate 421 can be released. Under the cooperation of the limiting ball 424 and the water sealing spring 425, the water sealing plate 421 can be reset to its corresponding limiting position. In addition, the core processor, the battery module, the communication module, and the pressure sensor 52 can all adopt the structures in the prior art, and their working principles and uses are well-known, so no more details will be described here.

[0035] The upper housing 2 is fixedly connected to the valve body 13 through a breaking mechanism 7. The breaking mechanism 7 includes an annular breaking pressure plate 71, an elastic pad 72, and a bolt assembly 73. The annular breaking pressure plate 71, the elastic pad 72, and the upper flange 22 of the upper housing 2 are arranged in sequence from top to bottom and are locked and fixed by the bolt assembly 73. Correspondingly, the bolt assembly 73 includes a plurality of locking bolts and a plurality of locking nuts. A plurality of pressing blocks 711 are fixedly arranged at the top of the inner edge of the annular breaking pressure plate 71 at equal intervals along its circumferential direction. Preferably, the number of the pressing blocks 711 is 4 - 8. The pressing blocks 711 are fixedly pressed against the upper end of the lower flange 131 of the valve body 13. An elastic pad 72 is also arranged between the lower flange 131 and the upper flange 22. A strip-shaped breaking seam 712 is arranged at the upper end of the connection between the pressing block 711 and the annular breaking pressure plate 71. The strength of the annular breaking pressure plate 71 is less than that of the upper flange 22 and the lower flange 131. Thus, when the bolt body 12 or the valve body 13 is subjected to a greater degree of impact, the pressing block 711 will break at the strip-shaped breaking seam 712, so that the pressing block 711 no longer tightly presses the lower flange 131 of the valve body 13. At this time, the valve body 13 is separated from the upper housing 2, effectively preventing the impact force from being further transmitted to the fire hydrant intelligent monitoring device 11. Thereby, the integrity of the bolt body 12, the valve body 13, and the fire hydrant intelligent monitoring device 11 is better ensured, which is beneficial to reducing subsequent maintenance costs. At the same time, the normal operation of the fire hydrant intelligent monitoring device 11 can be well ensured, and a good water sealing effect can be achieved smoothly.

[0036] In addition, a positioning assembly is arranged between the upper flange 22 and the lower flange 131. The positioning assembly includes a positioning block 81 and a positioning hole 82. A plurality of the positioning blocks 81 are fixedly arranged on the upper end surface of the lower flange 131. A plurality of the positioning holes 82 are arranged on the lower end surface of the upper flange 22. The positioning blocks 81 are adapted to the positioning holes 82 and are inserted into the positioning holes 82. Thus, it is convenient to quickly position the installation between the valve body 13 and the upper housing 2, and at the same time, the lateral stability when the valve body 13 and the upper housing 2 are connected can be further improved. Preferably, the number of both the positioning blocks 81 and the positioning holes 82 is 3 - 5.
