Description

Technical Field

[0001] This invention belongs to the field of fire safety valve technology, specifically relating to a fire-fighting positioning alarm intelligent safety valve. Background Technology

[0002] A safety valve is an automatic control device used to protect pressure vessels, pipelines, and equipment from excessive pressure. Its main function is to automatically open and discharge part of the medium when the pressure in the system exceeds a set value, thereby reducing the system pressure and preventing safety accidents such as equipment or pipeline rupture or explosion. However, fire alarm safety valves are usually connected to the alarm equipment of the fire protection system. While releasing excessive pressure, they also trigger the alarm system to remind staff that the system has abnormal pressure and ensure that remedial measures are taken in time.

[0003] The pressure setting of existing fire alarm safety valves is usually adjustable. However, the handwheel of these valves is often exposed on the outside of the valve cover, allowing passersby to easily turn it and alter the valve's pressure setting. If the opening pressure is set too high, it may damage the pipeline under excessive pressure. If it is set too low, it may cause the valve to open frequently, affecting system stability and causing frequent false alarms. Too many false alarms may lead to signal confusion in the system, causing staff to ignore the real alarm and delaying the emergency response. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fire-fighting positioning alarm intelligent safety valve.

[0005] The technical solution adopted to solve the above technical problems is: a fire positioning alarm intelligent safety valve, including a valve body, a first valve cover fixedly connected to the top of the valve body, and a limiting seat fixedly connected between the valve body and the first valve cover;

[0006] A second valve cover is fixedly connected to the top of the first valve cover. A sealing mechanism is provided at the center of the first valve cover, and an adjustment mechanism is installed on the top of the sealing mechanism.

[0007] The second valve cover has a rotating mechanism inside, a limiting mechanism outside the rotating mechanism, and an alarm mechanism inside the limiting mechanism.

[0008] Furthermore, a first valve seat is fixedly connected to the bottom of the valve body, a ring seat is fixedly connected to the top outer wall of the first valve seat, a second valve seat is fixedly connected to one side of the valve body, and the valve body is connected to the fire water pipe through the first valve seat.

[0009] With the above technical solution, when a fire occurs, the water pump delivers water from the water tower to the fire water pipe, which increases the pressure in the fire water pipe. The medium in the fire water pipe is delivered into the valve body through the first valve seat and finally discharged outward through the second valve seat, reducing the pressure in the fire water pipe. When the ring seat and the sealing mechanism are in contact, the sealing effect is improved.

[0010] Furthermore, an installation ring is fixedly connected to the inner wall of the first valve cover, and a contact switch is fixedly connected to the bottom end of the installation ring. Two first limiting grooves are formed at the top end of the inner wall of the first valve cover.

[0011] Through the above technical solution, when a fire occurs, the pressure inside the fire water pipe reaches its maximum value, causing the parts inside the sealing mechanism to contact and close the switch, triggering the alarm and prompting staff to evacuate immediately. When the fire protection system malfunctions, the pressure inside the fire water pipe will also increase, triggering the alarm again, allowing staff to take immediate measures to repair the system and extending the service life of the safety valve.

[0012] Furthermore, two second limiting grooves are formed in the center of the inner wall of the second valve cover, a fixing plate is fixedly connected to the inner wall of the second valve cover near the upper position of the two second limiting grooves, an alarm is fixedly installed on one side of the outer wall of the second valve cover, and a first pointer is fixedly connected to the front end of the outer wall of the second valve cover.

[0013] Through the above technical solutions, the alarms can sound in the event of a fire, a malfunction in the fire protection system, or when the pressure value of the safety valve is arbitrarily changed, providing information immediately so that staff can take emergency measures at the first opportunity.

[0014] Furthermore, the sealing mechanism includes a sealing seat fixedly connected to the top of the limiting seat, a sealing block slidably connected inside the limiting seat, a valve stem fixedly connected to the top of the sealing block, a sealing ring fixedly connected to the bottom of the outer wall of the sealing block, a spring seat fixedly connected to the outer wall of the valve stem, two first sliders fixedly connected to the center of the spring seat, an adjusting seat provided at the top of the inside of the first valve cover, two second sliders fixedly connected to the outer wall of the adjusting seat, the two second sliders slidably connected to the corresponding first limiting grooves, a circular groove opened at the top of the adjusting seat, a sleeve fixedly connected to the bottom of the adjusting seat, the bottom end of the sleeve fixedly connected to the top of the sealing seat, two third limiting grooves opened at the bottom of the outer wall of the sleeve, the valve stem slidably connected inside the sleeve, the two first sliders slidably connected to the corresponding third limiting grooves, and a first spring fixedly connected between the spring seat and the adjusting seat.

[0015] With the above technical solution, when the pressure inside the fire water pipe increases, the medium inside the fire pipeline flows into the valve body through the first valve seat, thereby pushing the sealing block, which in turn pushes the valve stem, causing the valve stem to slide inside the sleeve. At the same time, the valve stem pushes the connected spring seat, causing the spring seat to press the first spring upward. At this time, the medium inside the fire pipeline flows into the valve body through the top of the first valve seat, completing the pressure relief process. After the pressure is relieved, the first spring returns to its original position, causing the sealing block to fit against the top of the first valve seat, and simultaneously causing the sealing ring to fit against the ring seat, achieving double sealing and preventing pressure leakage inside the fire pipeline.

[0016] Furthermore, the adjusting mechanism includes a threaded disc fixedly connected to the bottom of the inner wall of the second valve cover, a threaded rod threadedly connected to the center of the threaded disc, a pressing plate fixedly connected to the bottom end of the threaded rod, the pressing plate being slidably connected to the circular groove, a fixing sleeve fixedly connected to the top end of the threaded rod, a plurality of annularly distributed limiting strips fixedly connected to the inner wall of the fixing sleeve, and a first touch switch fixedly connected to the center of the bottom inner surface of the fixing sleeve.

[0017] With the above technical solution, when the threaded rod rotates inside the threaded disc, it drives the extrusion plate to move downwards, and at the same time, it extrudes the adjusting seat downwards, causing the adjusting seat to compress the first spring, which increases the compression force of the first spring and increases the opening pressure of the sealing block. Similarly, when the threaded rod rotates in the opposite direction, it reduces the opening pressure of the sealing block, thereby achieving pressure regulation of the safety valve. When the rotating mechanism is rotated arbitrarily and the alarm is triggered, the operator needs to adjust the rotating mechanism to touch the first touch switch to turn off the alarm.

[0018] Furthermore, the rotating mechanism includes a movable disc disposed at the center of the interior of the second valve cover. Two third sliders are fixedly connected to the outer wall of the movable disc. The two third sliders are slidably connected to the corresponding second limiting grooves. A second spring is fixedly connected between the movable disc and the fixed plate. A rotating rod is rotatably connected to the center of the movable disc. The rotating rod is rotatably connected to the fixed plate. A positioning cone is fixedly connected to the bottom end of the rotating rod. A connecting sleeve is fixedly connected to the outer wall of the rotating rod near the top of the positioning cone. A plurality of annularly distributed positioning arc blocks are fixedly connected to the bottom of the connecting sleeve. A slot is provided between the plurality of positioning arc blocks. A handwheel is fixedly connected to the top of the rotating rod. A limiting pin is fixedly connected to the center of one side of the outer wall of the rotating rod. A second pointer is fixedly connected to the top of one side of the outer wall of the rotating rod. The limiting pin is aligned with the second pointer.

[0019] With the above technical solution, when the safety valve section pressure needs to be adjusted, push the handwheel to move the rotating rod downward, thereby causing the positioning cone to insert into the fixed sleeve. When multiple positioning arc blocks contact the corresponding limit strips, since the contact surfaces of the positioning arc blocks and limit strips are both conical, they contact each other to achieve automatic positioning, causing multiple limit strips to insert into the corresponding slots. At this time, turn the handwheel to drive the connecting sleeve to rotate, thereby driving the fixed sleeve to rotate, and then driving the threaded rod to rotate, causing the extrusion plate to press against the adjusting seat, thereby achieving pressure adjustment. This allows for precise control of the opening pressure of the safety valve, protecting the equipment from damage.

[0020] Furthermore, the limiting mechanism includes a limiting sleeve fixedly connected to the top of the fixed plate. The inner wall of the limiting sleeve has a first sliding groove at its center, a second sliding groove near the top of the first sliding groove, a third sliding groove near the top of the second sliding groove, a fourth sliding groove near the end of the third sliding groove, and a fifth sliding groove near the bottom of the fourth sliding groove. The fifth sliding groove is located below the first sliding groove, and the inner wall of the limiting sleeve has two mounting grooves at its center.

[0021] With the above technical solution, when a passerby randomly turns the handwheel, the handwheel drives the lever to rotate, which in turn drives the limit pin to rotate in the first slide groove, thereby triggering the alarm mechanism and causing the alarm to sound. Staff will then take immediate measures to prevent damage to the pressure in the fire extinguishing pipeline, which could affect the entire fire extinguishing system. When staff are adjusting the safety valve pressure normally, they pull the handwheel upwards, causing the limit pin to slide to the top of the second slide groove. Then, they turn the handwheel 90° to the right, causing the limit pin to slide to one end of the third slide groove. Finally, they push the handwheel downwards, causing the limit pin to slide into the fifth slide groove. At this point, the alarm mechanism will not be triggered, and the alarm will not sound, greatly improving the protection of the safety valve.

[0022] Furthermore, the first slide groove is connected to the second slide groove, the second slide groove is connected to the third slide groove, the third slide groove is connected to the fourth slide groove, the fourth slide groove is connected to the fifth slide groove, and the limiting pin is slidably connected to the center position of the first slide groove.

[0023] With the above technical solution, when the limit pin rotates in the fifth slide groove, the second pointer can be observed. The position of the limit pin rotation is the same as the second pointer. At the same time, the first pointer is aligned with the position of the fourth slide groove. When the limit pin needs to be reset in the fifth slide groove, the first pointer can be observed for rotation adjustment, which facilitates quick reset. Multiple channels are set to prevent passers-by from pushing or rotating the pin at will, thus strengthening the protection of the handwheel.

[0024] Furthermore, the alarm mechanism includes a third spring fixedly connected to two mounting slots, and a second touch switch fixedly connected to the inner end of each of the two third springs. The two second touch switches are slidably connected to the corresponding mounting slots. A turntable is fixedly connected to the outer wall of the rotating rod inside the limiting sleeve. A first slot is opened on both sides of the outer wall of the turntable, and a second slot is opened at the front and rear ends of the outer wall of the turntable.

[0025] With the above technical solution, when the handwheel is turned at will, the rotating rod drives the turntable to rotate, causing the turntable to contact the two second touch switches, triggering the alarm. When the operator adjusts the safety valve pressure normally, the turntable is first moved upward, and then rotated 90°. At this time, the two second slots are aligned with the corresponding second touch switches. When the turntable moves downward, it will not contact the two second touch switches, so the alarm will not sound, greatly improving the protection of the safety valve.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of adjustment mechanism, rotation mechanism and limit mechanism, makes it impossible for ordinary personnel to adjust the pressure of safety valve at will, thereby improving the protection of safety valve. At the same time, the mechanism can accurately control the opening pressure of safety valve, protecting equipment from damage; (2) The present invention, through the setting of alarm and alarm mechanism, will alarm when ordinary personnel rotate it at will, and staff will take measures immediately to prevent the pressure value in the fire pipeline from being damaged, affecting the entire fire extinguishing system. At the same time, when staff adjust the pressure of safety valve normally, the alarm will not alarm, greatly improving the protection of safety valve; (3) The present invention, through the design of sealing mechanism, after pressure relief, the sealing block fits with the top of the first valve seat, and at the same time the sealing ring fits with the ring seat, achieving double sealing, preventing pressure leakage in the fire pipeline, greatly improving the sealing performance of the safety valve. When a fire occurs, the parts in the sealing mechanism contact the contact switch, the alarm will work and alarm, prompting staff to escape immediately. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] like Figures 1-11As shown, a fire-fighting positioning alarm intelligent safety valve of this embodiment includes a valve body 1. A first valve seat 11 is fixedly connected to the bottom of the valve body 1, and a ring seat 12 is fixedly connected to the outer wall of the top of the first valve seat 11. A second valve seat 13 is fixedly connected to one side of the valve body 1. The valve body 1 is connected to a fire water pipe through the first valve seat 11. In the event of a fire, the water pump delivers water from the water tower to the fire water pipe, increasing the pressure inside the fire water pipe. The medium inside the fire water pipe is delivered into the valve body 1 through the first valve seat 11 and finally discharged outward through the second valve seat 13, reducing the pressure inside the fire water pipe. When the ring seat 12 is in contact with the sealing mechanism 5, the sealing effect is improved. A first valve cover 2 is fixedly connected to the top of the valve body 1. An installation ring bracket 21 is fixedly connected to the inner wall of the first valve cover 2. A contact switch 22 is fixedly connected to the bottom end of the installation ring bracket 21. Two first limiting grooves 23 are opened at the top of the inner wall of the first valve cover 2. In the event of a fire, the pressure inside the fire water pipe reaches its maximum value, causing the sealing mechanism 5 to... When the parts contact the contact switch 22, the alarm 43 will activate and sound an alarm, prompting personnel to evacuate immediately. When the fire protection system malfunctions, the pressure in the fire water pipe will also increase, triggering the alarm 43 to sound an alarm as well, allowing personnel to take immediate measures to repair the system and extend the service life of the safety valve. A limit seat 3 is fixedly connected between the valve body 1 and the first valve cover 2. A second valve cover 4 is fixedly connected to the top of the first valve cover 2. Two second limit grooves 41 are opened in the center of the inner wall of the second valve cover 4. A fixing plate 42 is fixedly connected to the inner wall of the second valve cover 4 near the upper part of the two second limit grooves 41. An alarm 43 is fixedly installed on one side of the outer wall of the second valve cover 4. A first pointer 44 is fixedly connected to the front end of the outer wall of the second valve cover 4. The alarm 43 can sound an alarm in the event of a fire, a malfunction in the fire protection system, or when the pressure value of the safety valve is arbitrarily changed, providing information immediately so that personnel can take emergency measures immediately.

[0041] like Figures 1-10As shown, a sealing mechanism 5 is provided at the center of the first valve cover 2. The sealing mechanism 5 includes a sealing seat 501 fixedly connected to the top of the limiting seat 3. A sealing block 503 is slidably connected inside the limiting seat 3. A valve stem 502 is fixedly connected to the top of the sealing block 503. A sealing ring 504 is fixedly connected to the bottom of the outer wall of the sealing block 503. A spring seat 505 is fixedly connected to the outer wall of the valve stem 502. Two first sliders 506 are fixedly connected to the center of the spring seat 505. An adjusting seat 507 is provided at the top of the inside of the first valve cover 2. Two second sliders 508 are fixedly connected to the outer wall of the adjusting seat 507. The two second sliders 508 are slidably connected to the corresponding first limiting grooves 23. A circular groove 509 is opened at the top of the adjusting seat 507. A sleeve 510 is fixedly connected to the bottom of the adjusting seat 507. The bottom end of the sleeve 510 is fixedly connected to the top of the sealing seat 501. Two third limiting grooves 511 are opened at the bottom of the outer wall of the sleeve 510. The valve stem 502 is slidably connected inside the sleeve 510. The first slider 506 is slidably connected to the corresponding third limiting groove 511. The first spring 512 is fixedly connected between the spring seat 505 and the adjusting seat 507. When the pressure in the fire water pipe increases, the spring seat 505 contacts the switch 22 upwards, and the alarm 43 works to sound an alarm. At this time, the medium in the fire pipeline flows into the valve body 1 through the first valve seat 11, thereby pushing the sealing block 503, which pushes the valve stem 502, causing the valve stem 502 to slide in the sleeve 510. At the same time, the valve stem 502 pushes the connected spring seat 505, causing the spring seat 505 to press the first spring 512 upwards. When the pressure is too high, the spring seat 505 moves upwards to contact the valve body 1. At this time, the medium in the fire pipeline flows into the valve body 1 through the top of the first valve seat 11, completing the pressure relief process. After the pressure is relieved, the first spring 512 returns to its original position, causing the sealing block 503 to contact the top of the first valve seat 11, and at the same time causing the sealing ring 504 to contact the ring seat 12, achieving double sealing and preventing pressure leakage in the fire pipeline.

[0042] like Figures 1-10As shown, an adjusting mechanism 6 is installed on the top of the sealing mechanism 5. The adjusting mechanism 6 includes a threaded disc 601 fixedly connected to the bottom of the inner wall of the second valve cover 4. A threaded rod 602 is threadedly connected to the center of the threaded disc 601. A pressing plate 603 is fixedly connected to the bottom end of the threaded rod 602. The pressing plate 603 is slidably connected to the circular groove 509. A fixing sleeve 604 is fixedly connected to the top end of the threaded rod 602. Multiple annularly distributed limiting strips 605 are fixedly connected to the inner wall of the fixing sleeve 604. A first touch switch 606 is fixedly connected to the center of the bottom inner surface of the fixing sleeve 604. When... When the threaded rod 602 rotates within the threaded disc 601, it drives the pressing plate 603 to move downwards, simultaneously pressing the adjusting seat 507 downwards. This causes the adjusting seat 507 to compress the first spring 512, increasing the compression force of the first spring 512 and raising the opening pressure of the sealing block 503. Similarly, when the threaded rod 602 rotates in the opposite direction, it reduces the opening pressure of the sealing block 503, thus regulating the pressure of the safety valve. When the rotating mechanism 7 is arbitrarily rotated and the alarm 43 is triggered, the operator needs to adjust the rotating mechanism 7 to touch the first touch switch 606 to turn off the alarm 43.

[0043] like Figures 1-11 As shown, the second valve cover 4 is equipped with a rotating mechanism 7 inside. The rotating mechanism 7 includes a movable disc 701 located at the center of the second valve cover 4. Two third sliders 702 are fixedly connected to the outer wall of the movable disc 701. The two third sliders 702 are slidably connected to the corresponding second limiting grooves 41. A second spring 703 is fixedly connected between the movable disc 701 and the fixed plate 42. A rotating rod 704 is rotatably connected to the center of the movable disc 701. The rotating rod 704 is rotatably connected to the fixed plate 42. A positioning cone 705 is fixedly connected to the bottom end of the rotating rod 704. A connecting sleeve 706 is fixedly connected to the outer wall of the rotating rod 704 near the top of the positioning cone 705. A plurality of annularly distributed positioning arc blocks 707 are fixedly connected to the bottom of the connecting sleeve 706. A slot 708 is opened between the plurality of positioning arc blocks 707. A handwheel 709 is fixedly connected to the top of the rotating rod 704. A handwheel 709 is fixedly connected to one side of the outer wall of the rotating rod 704. The valve is fixedly connected to a limit pin 710. A second pointer 711 is fixedly connected to the top of one side of the outer wall of the rotating rod 704. The limit pin 710 is aligned with the second pointer 711. When the safety valve pressure needs to be adjusted, the handwheel 709 is pushed, causing the rotating rod 704 to move downward, thereby causing the positioning cone 705 to insert into the fixed sleeve 604. When multiple positioning arc blocks 707 contact the corresponding limit strips 605, since the contact surfaces of the positioning arc blocks 707 and the limit strips 605 are both conical, they contact each other to achieve automatic positioning, causing multiple limit strips 605 to insert into the corresponding slots 708. At this time, the handwheel 709 is rotated, causing the connecting sleeve 706 to rotate, thereby causing the fixed sleeve 604 to rotate, and then causing the threaded rod 602 to rotate, causing the extrusion plate 603 to extrude the adjusting seat 507, thereby achieving pressure adjustment. This allows for precise control of the opening pressure of the safety valve, protecting the equipment from damage.

[0044] like Figures 1-10 As shown, a limiting mechanism 8 is provided on the outer side of the rotating mechanism 7. The limiting mechanism 8 includes a limiting sleeve 801 fixedly connected to the top of the fixing plate 42. A first sliding groove 802 is formed in the center of the inner wall of the limiting sleeve 801. A second sliding groove 803 is formed on the inner wall of the limiting sleeve 801 near the top of the first sliding groove 802. A third sliding groove 804 is formed on the inner wall of the limiting sleeve 801 near the top of the second sliding groove 803. A fourth sliding groove 805 is formed on the inner wall of the limiting sleeve 801 near the end of the third sliding groove 804. A fifth sliding groove 805 is formed on the inner wall of the limiting sleeve 801 near the bottom of the fourth sliding groove 805. The fifth slide groove 806 is located below the first slide groove 802. Two mounting slots 807 are formed in the center of the inner wall of the limiting sleeve 801. When a passerby randomly turns the handwheel 709, the handwheel 709 drives the rotating rod 704 to rotate, which in turn drives the limiting pin 710 to rotate within the first slide groove 802, thereby triggering the alarm mechanism 9 and causing the alarm 43 to sound. Personnel will immediately take measures to prevent damage to the pressure value within the fire pipeline, which could affect the entire fire extinguishing system. When personnel are normally adjusting the safety valve pressure, they pull the handwheel upwards. Handwheel 709 drives limit pin 710 to the top of the second slide groove 803. Then, turntable 903 rotates 90° to the right, causing limit pin 710 to slide to one end of the third slide groove 804. Then, push handwheel 709 downwards, causing limit pin 710 to slide into the fifth slide groove 806. At this point, alarm mechanism 9 will not be triggered, and alarm 43 will not sound, greatly improving the protection of the safety valve. The first slide groove 802 is connected to the second slide groove 803, the second slide groove 803 is connected to the third slide groove 804, the third slide groove 804 is connected to the fourth slide groove 805, and the fourth slide groove 806... 5 is connected to the fifth slide groove 806. The limiting pin 710 is slidably connected to the center position of the first slide groove 802. When the limiting pin 710 rotates in the fifth slide groove 806, the second pointer 711 can be observed. The position of the limiting pin 710 is the same as that of the second pointer 711. At the same time, the first pointer 44 is aligned with the position of the fourth slide groove 805. When it is necessary to reset the limiting pin 710 in the fifth slide groove 806, the first pointer 44 can be observed for rotation adjustment, which facilitates quick reset. Multiple channels are set to prevent passers-by from pushing or rotating the adjustment at will, and to strengthen the protection of the handwheel 709.

[0045] like Figures 1-11As shown, an alarm mechanism 9 is installed inside the limiting mechanism 8. The alarm mechanism 9 includes a third spring 901 fixedly connected to two mounting slots 807. A second touch switch 902 is fixedly connected to the inner end of each of the two third springs 901. The two second touch switches 902 are slidably connected to their corresponding mounting slots 807. A turntable 903 is fixedly connected to the outer wall of the rotating rod 704 inside the limiting sleeve 801. A first slot 904 is opened on both sides of the outer wall of the turntable 903, and a second slot 905 is opened at both the front and rear ends of the outer wall of the turntable 903. When the handwheel 70... When the lever 704 is rotated, it drives the turntable 903 to rotate, causing the turntable 903 to contact the two second touch switches 902, thus triggering the alarm 43. When the operator adjusts the safety valve pressure normally, the turntable 903 is first moved upward, and then rotated 90° to the right. At this time, the two second slots 905 are aligned with the corresponding second touch switches 902. When the turntable 903 moves downward, it will not contact the two second touch switches 902, thus preventing the alarm 43 from triggering and greatly improving the protection of the safety valve.

[0046] The working principle of this embodiment is as follows: When a fire occurs, the water pump delivers water from the water tower to the fire water pipe, increasing the pressure inside the fire water pipe. The medium inside the fire water pipe is delivered to the valve body 1 through the first valve seat 11, thereby pushing the sealing block 503. The sealing block 503 pushes the valve stem 502, causing the valve stem 502 to slide inside the sleeve 510. At the same time, the valve stem 502 pushes the connected spring seat 505, causing the spring seat 505 to press the first spring 512 upward. At this time, the medium in the fire pipeline flows into the valve body 1 through the top of the first valve seat 11 and is discharged outward through the second valve seat 13, completing the pressure relief process. After the pressure relief, the first spring 512 returns to its original position, causing the sealing block 503 to fit against the top of the first valve seat 11, and at the same time causing the sealing ring 504 to fit against the ring seat 12, achieving double sealing.

[0047] When the handwheel 709 is turned at will, it causes the rotating rod 704 to rotate, which in turn causes the limiting pin 710 to rotate in the first slide groove 802. At the same time, the rotating rod 704 causes the turntable 903 to rotate, so that when the turntable 903 rotates, it contacts the two second touch switches 902, causing the alarm 43 to sound.

[0048] When the operator adjusts the safety valve pressure normally, pulling up the handwheel 709 causes the limit pin 710 to slide to the top of the second slide groove 803. Then, rotating the turntable 903 90° to the right causes the limit pin 710 to slide to one end of the third slide groove 804. Finally, pushing the handwheel 709 downwards causes the limit pin 710 to slide into the fifth slide groove 806. At this point, the alarm mechanism 9 will not be triggered, and the alarm 43 will not sound.

[0049] This triggers the alarm mechanism 9, causing the alarm 43 to sound. Staff will take immediate measures to prevent damage to the pressure value in the fire pipeline, which could affect the entire fire extinguishing system. When staff are adjusting the safety valve pressure, they pull up the handwheel 709, causing the limit pin 710 to slide to the top of the second slide groove 803. Then, they rotate the turntable 903 90° to the right, causing the limit pin 710 to slide to one end of the third slide groove 804. Then, they push the handwheel 709 down, aligning the two second slots 905 on the turntable 903 with the corresponding second touch switches 902. When the turntable 903 moves down, the limit pin 710 slides into the fifth slide groove 806, preventing it from touching the two second touch switches 902 and thus preventing the alarm 43 from sounding.

[0050] When the limiting pin 710 slides into the fifth slide groove 806, the operator continues to push the handwheel 709, causing the handwheel 709 to push the rotating rod 704, thereby driving the positioning cone 705 to insert into the fixing sleeve 604. When multiple positioning arc blocks 707 contact the corresponding limiting strip 605 (when the limiting strip 605 contacts the center of the inclined surface of the positioning arc block 707, since the limiting pin 710 can rotate freely in the fifth slide groove 806, the handwheel 709 can be slowly rotated left and right for positioning, so that the limiting strip 605 is aligned with the slot 708), due to the positioning arc block 707 and the limiting strip 605, The contact surfaces of the five are all conical, and they contact each other to achieve automatic positioning, so that multiple limit bars 605 are inserted into the corresponding slots 708. At this time, the handwheel 709 is turned, which drives the connecting sleeve 706 to rotate, thereby driving the fixed sleeve 604 to rotate, and then driving the threaded rod 602 to rotate, so that the pressing plate 603 presses the adjusting seat 507 downward, and the adjusting seat 507 presses the first spring 512, which increases the compression force of the first spring 512 and increases the opening pressure of the sealing block 503. Similarly, the threaded rod 602 rotates in the opposite direction, reducing the opening pressure of the sealing block 503. At this time, the alarm 43 will not sound.

[0051] After adjustment, the staff can observe the second pointer 711. The position of the limit pin 710 is the same as that of the second pointer 711. At the same time, observe the first pointer 44. The first pointer 44 is aligned with the position of the fourth slide groove 805. When the second pointer 711 is aligned with the first pointer 44, the handwheel 709 moves upward, driving the limit pin 710 to slide to the top of the fourth slide groove 805, and then turns to the left to slide to one end of the third slide groove 804. At this time, the second spring 703 drives the limit pin 710 to reset, completing the overall reset of the safety valve.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
