Description

Technical Field

[0001] The invention belongs to the technical field of fire safety valves, and in particular relates to a fire positioning alarm intelligent safety valve. Background Art

[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 the set value, thereby reducing the system pressure and preventing safety accidents such as equipment or pipeline rupture and explosion. However, the fire alarm safety valve is usually connected to the alarm equipment of the fire protection system. While releasing the excessive pressure, it will also trigger the alarm system to remind the staff that the system has abnormal pressure and ensure that remedial measures are taken in time.

[0003] The pressure value in the existing fire alarm safety valve can usually be adjusted. However, the handwheel of the existing fire alarm safety valve is usually exposed on the outside of the valve cover. Passers-by can turn the handwheel at will, causing the pressure setting value of the safety valve to be changed. If the opening pressure of the safety valve is set too high, the pipeline may be damaged under excessive pressure. If it is set too low, the valve may be opened frequently, affecting the stability of the system and causing the safety valve to alarm frequently. Too many false alarms may cause signal confusion in the system, and the staff may ignore the real alarm, thereby delaying the timing of emergency response. Summary of the invention

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

[0005] The technical solution adopted to solve the above technical problems is: a fire positioning alarm intelligent safety valve, comprising a valve body, a first valve cover is fixedly connected to the top of the valve body, and a limited position seat is fixedly connected between the valve body and the first valve cover; The top of the first valve cover is fixedly connected to the second valve cover, the center of the first valve cover is provided with a sealing mechanism, and the top of the sealing mechanism is installed with an adjusting mechanism; A rotating mechanism is provided inside the second valve cover, a limiting mechanism is provided outside the rotating mechanism, and an alarm mechanism is installed inside the limiting mechanism.

[0006] 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.

[0007] Through the above technical solution, when a fire occurs, the water pump transports water in 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 transported into the valve body through the first valve seat and finally discharged to the outside through the second valve seat, thereby reducing the pressure in the fire water pipe and improving the sealing effect when the ring seat and the sealing mechanism are in contact.

[0008] Furthermore, a mounting ring frame is fixedly connected to the inner wall of the first valve cover, a fitting switch is fixedly connected to the bottom end of the mounting ring frame, and two first limiting grooves are provided at the top end of the inner wall of the first valve cover.

[0009] Through the above technical solution, when a fire occurs, the pressure in the fire water pipe reaches the maximum value, causing the parts in the sealing mechanism to contact the fitting switch, and the alarm will work to sound an alarm, prompting the staff to escape as soon as possible. When the fire protection system fails, the pressure in the fire water pipe will also increase, and the alarm will also sound an alarm, allowing the staff to take measures to repair it as soon as possible, thereby increasing the service life of the safety valve.

[0010] Furthermore, two second limiting grooves are opened 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.

[0011] Through the above technical solution, the alarm can sound an alarm when a fire occurs, when a fire protection system fails, or when the pressure value of the safety valve is changed at will. It can provide information in the first time, allowing the staff to take emergency measures in the first time.

[0012] Furthermore, the sealing mechanism includes a sealing seat fixedly connected to the top of the limit seat, the limit seat is slidably connected with a sealing block inside, the top of the sealing block is fixedly connected to a valve stem, the bottom end of the outer wall of the sealing block is fixedly connected to a sealing ring, the outer wall of the valve stem is fixedly connected to a spring seat, the center of the spring seat is fixedly connected with two first sliding blocks, an adjustment seat is provided at the inner top end of the first valve cover, the outer wall of the adjustment seat is fixedly connected with two second sliding blocks, the two second sliding blocks are slidably connected to the corresponding first limit grooves, a circular groove is provided at the top of the adjustment seat, a sleeve is fixedly connected to the bottom of the adjustment seat, the bottom end of the sleeve is fixedly connected to the top of the sealing seat, two third limit grooves are provided at the bottom end of the outer wall of the sleeve, the valve stem is slidably connected in the sleeve, the two first sliding blocks are slidably connected to the corresponding third limit grooves, and a first spring is fixedly connected between the spring seat and the adjustment seat.

[0013] Through the above technical solution, when the pressure in the fire water pipe increases, the medium in the fire pipe flows into the valve body through the first valve seat, thereby pushing the sealing block, so that the sealing block pushes the valve stem, so that the valve stem slides in the sleeve, and at the same time the valve stem pushes the connected spring seat, so that the spring seat squeezes the first spring upward. At this time, the medium in the fire pipe flows into the valve body through the top of the first valve seat, completing the pressure relief process. After the pressure relief, the first spring resets, driving the sealing block to fit against the top of the first valve seat, and at the same time driving the sealing ring to fit against the ring seat, achieving double sealing and preventing pressure leakage in the fire pipe.

[0014] Furthermore, the adjustment mechanism includes a threaded disk fixedly connected to the bottom end of the inner wall of the second valve cover, the threaded disk is threadedly connected to a threaded rod at the center, the bottom end of the threaded rod is fixedly connected to an extrusion plate, the extrusion plate is slidably connected to the circular groove, the top end of the threaded rod is fixedly connected to a fixed sleeve, the inner wall of the fixed sleeve is fixedly connected to a plurality of annularly distributed limit strips, and the center of the bottom inner surface of the fixed sleeve is fixedly connected to a first touch switch.

[0015] Through the above technical scheme, when the threaded rod rotates in the threaded disk, it drives the extrusion plate to move downward, and at the same time squeezes the adjusting seat downward, so that the adjusting seat squeezes the first spring, making the compression elastic force of the first spring larger, thereby increasing the opening pressure of the sealing block. Similarly, the threaded rod rotates in the opposite direction to reduce the opening pressure of the sealing block, thereby realizing the pressure regulation of the safety valve. When the rotating mechanism is rotated arbitrarily and the alarm sounds, the staff needs to adjust the rotating mechanism to touch the first touch switch to turn off the alarm.

[0016] Furthermore, the rotating mechanism includes a movable disk arranged at the center of the second valve cover, the outer wall of the movable disk is fixedly connected with two third sliding blocks, the two third sliding blocks are slidably connected to the corresponding second limit grooves, the movable disk is fixedly connected with a second spring between the fixed plate, the center of the movable disk is rotatably connected with a rotating rod, the rotating rod is rotatably connected to the fixed plate, the bottom end of the rotating rod is fixedly connected with a positioning cone, the outer wall of the rotating rod is fixedly connected with a connecting sleeve near the top of the positioning cone, the bottom of the connecting sleeve is fixedly connected with a plurality of annularly distributed positioning arc blocks, and slots are provided between the plurality of positioning arc blocks, the top of the rotating rod is fixedly connected with a handwheel, the center of one side of the outer wall of the rotating rod is fixedly connected with a limiting pin, the top of one side of the outer wall of the rotating rod is fixedly connected with a second pointer, and the limit pin is aligned with the second pointer.

[0017] Through the above technical solution, when the pressure of the safety valve needs to be adjusted, the handwheel is pushed so that the handwheel drives the rotating rod to move downward, thereby driving 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 the limit strips are both conical, they contact each other to achieve automatic positioning, so that multiple limit strips are inserted into the corresponding slots. At this time, the handwheel is turned to drive the connecting sleeve to rotate, thereby driving the fixed sleeve to rotate, and then driving the threaded rod to rotate, so that the extrusion plate squeezes the adjustment seat to achieve pressure adjustment, which can accurately control the opening pressure of the safety valve and protect the equipment from damage.

[0018] Furthermore, the limiting mechanism includes a limiting sleeve fixedly connected to the top of the fixed plate, a first slide groove is opened at the center of the inner wall of the limiting sleeve, a second slide groove is opened at the inner wall of the limiting sleeve near the top of the first slide groove, a third slide groove is opened at the inner wall of the limiting sleeve near the top of the second slide groove, a fourth slide groove is opened at one end of the inner wall of the limiting sleeve near the third slide groove, a fifth slide groove is opened at the inner wall of the limiting sleeve near the bottom of the fourth slide groove, the fifth slide groove is located below the first slide groove, and two mounting grooves are opened at the center of the inner wall of the limiting sleeve.

[0019] Through the above technical scheme, when a passerby turns the handwheel at will, the handwheel drives the rotating rod to rotate, and the rotating rod drives the limit pin to rotate in the first slide groove, thereby triggering the alarm mechanism and causing the alarm to sound. The staff will take measures as soon as possible to prevent the pressure value in the fire pipe from being damaged and affecting the entire fire extinguishing system. When the staff normally adjusts the pressure of the safety valve, they pull up the handwheel to drive the limit pin to slide to the top of the second slide groove, then turn the handwheel 90° to the right, drive the limit pin to slide to one end of the third slide groove, and then push the handwheel downward to make the limit pin slide into the fifth slide groove. At this time, the alarm mechanism will not be triggered and the alarm will not sound, which greatly improves the protection of the safety valve.

[0020] Furthermore, the first slide slot is connected to the second slide slot, the second slide slot is connected to the third slide slot, the third slide slot is connected to the fourth slide slot, the fourth slide slot is connected to the fifth slide slot, and the limit pin is slidably connected to the center position of the first slide slot.

[0021] Through the above technical solution, when the limit pin rotates in the fifth slide groove, the second pointer can be observed, and 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 is convenient for quick reset. Multiple channels are set to prevent passers-by from pushing or rotating the adjustment at will, thereby strengthening the protection of the hand wheel.

[0022] Furthermore, the alarm mechanism includes a third spring fixedly connected to two mounting grooves, the inner ends of the two third springs are fixedly connected to a second touch switch, the two second touch switches are slidably connected to the corresponding mounting grooves, the outer wall of the rotating rod is located in the limit sleeve and is fixedly connected to a turntable, the outer wall of the turntable is provided with a first slot on both sides, and the outer wall of the turntable is provided with a second slot at the front and rear ends.

[0023] Through the above technical solution, when the handwheel is rotated at will, the rotating rod drives the turntable to rotate, so that when the turntable rotates, it contacts the two second touch switches, causing the alarm to sound. When the staff normally adjusts the pressure of the safety valve, they first drive the turntable to move upward, and then rotate the turntable 90°. At this time, the two second notches are aligned with the corresponding second touch switches. When the turntable moves downward, it will not touch the two second touch switches, so that the alarm will not sound, which greatly improves the protection of the safety valve.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs an adjustment mechanism, a rotation mechanism and a limit mechanism, so that ordinary people cannot adjust the pressure of the safety valve at will, thereby improving the protection of the safety valve. At the same time, the mechanism can accurately control the opening pressure of the safety valve to protect the equipment from damage; (2) The present invention sets an alarm and an alarm mechanism. When ordinary people rotate it at will, the alarm will sound, and the staff will take measures at the first time to prevent the pressure value in the fire pipe from being damaged and affecting the entire fire extinguishing system. At the same time, when the staff normally adjusts the pressure of the safety valve, the alarm will not sound, which greatly improves the protection of the safety valve; (3) The present invention designs a sealing mechanism. After the pressure is released, the sealing block fits with the top of the first valve seat, and the sealing ring fits with the ring seat to achieve double sealing, prevent the pressure leakage in the fire pipe, and greatly improve the sealing of the safety valve. When a fire occurs, the parts in the sealing mechanism contact and fit the switch, and the alarm works to sound an alarm, prompting the staff to escape at the first time.

The valve body 1 is connected to the fire water pipe through the first valve seat 11. When a fire occurs, the water pump transports water in the water tower to the fire water pipe, so that the pressure in the fire water pipe increases, and the medium in the fire water pipe is transported to the valve body 1 through the first valve seat 11, and finally discharged outward through the second valve seat 13, so as to reduce the pressure in the fire water pipe. When the ring seat 12 is fitted with the sealing mechanism 5, the sealing effect is improved.

The top of the inner wall of the first valve cover 2 is provided with two first limiting grooves 23. When a fire occurs, the pressure in the fire water pipe reaches the maximum value, so that the sealing mechanism 5 The parts contact and fit the switch 22, and the alarm 43 works to alarm, prompting the staff to escape as soon as possible. When the fire protection system fails, the pressure in the fire protection water pipe will also increase, and the alarm 43 will also alarm, so that the staff can take measures to repair it as soon as possible, thereby improving the service life of the safety valve. The valve body 1 is fixedly connected to the first valve cover 2 with a limited seat 3, and the top of the first valve cover 2 is fixedly connected to the second valve cover 4. Two second limiting grooves 41 are provided 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 position of the two second limiting grooves 41. An alarm 43 is fixedly installed on one side of the outer wall of the second valve cover 4, and a first pointer 44 is fixedly connected to the front end of the outer wall of the second valve cover 4.

When the pressure is too large, the spring seat 505 moves upward to contact. At this time, the medium in the fire pipe flows into the valve body 1 through the top of the first valve seat 11, completing the pressure relief process. After the pressure relief, the first spring 512 resets, drives the sealing block 503 to fit with the top of the first valve seat 11, and drives the sealing ring 504 to fit with the ring seat 12, so as to achieve double sealing and prevent pressure leakage in the fire pipe.

Similarly, the threaded rod 602 rotates in the opposite direction to reduce the opening pressure of the sealing block 503, thereby realizing pressure regulation of the safety valve. When the rotating mechanism 7 is rotated arbitrarily and the alarm 43 sounds an alarm, the staff needs to adjust the rotating mechanism 7 to touch the first touch switch 606 to turn off the alarm 43.

[0034] The working principle of this embodiment is as follows. When a fire occurs, the water pump transports water in the water tower to the fire water pipe, so that the pressure in the fire water pipe increases, and the medium in the fire water pipe is transported to the valve body 1 through the first valve seat 11, thereby pushing the sealing block 503, so that the sealing block 503 pushes the valve stem 502, so that the valve stem 502 slides in the sleeve 510, and at the same time, the valve stem 502 pushes the connected spring seat 505, so that the spring seat 505 squeezes the first spring 512 upward. At this time, the medium in the fire pipe 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 resets, driving the sealing block 503 to fit with the top of the first valve seat 11, and at the same time driving the sealing ring 504 to fit with the ring seat 12, to achieve double sealing; When the hand wheel 709 is rotated at will, the hand wheel 709 drives the rotating rod 704 to rotate, so that the rotating rod 704 drives the limiting pin 710 to rotate in the first sliding groove 802, and at the same time, the rotating rod 704 drives the rotating disk 903 to rotate, so that the rotating disk 903 contacts the two second touch switches 902 when rotating, so that the alarm 43 sounds an alarm; When the staff normally adjusts the pressure of the safety valve, they pull up the hand wheel 709 to drive the limit pin 710 to slide to the top of the second slide groove 803, and then turn the turntable 903 to the right by 90° to drive the limit pin 710 to slide to one end of the third slide groove 804, and then push the hand wheel 709 downward to make the limit pin 710 slide into the fifth slide groove 806. At this time, the alarm mechanism 9 will not be triggered, and the alarm 43 will not sound. The alarm mechanism 9 is thereby triggered, causing the alarm 43 to sound an alarm. The staff will take measures immediately to prevent the pressure value in the fire pipe from being damaged and affecting the entire fire extinguishing system. When the staff normally adjusts the pressure of the safety valve, they pull up the hand wheel 709 to drive the limit pin 710 to slide to the top of the second slide groove 803, and then turn the turntable 903 to the right by 90° to drive the limit pin 710 to slide to one end of the third slide groove 804, and then push the hand wheel 709 downward to align the two second notches 905 on the turntable 903 with the corresponding second touch switches 902. When the turntable 903 moves downward, the limit pin 710 slides into the fifth slide groove 806 and does not touch the two second touch switches 902, so that the alarm 43 does not sound an alarm. When the limiting pin 710 slides into the fifth slide groove 806, the staff continues to push the hand wheel 709, so that the hand wheel 709 pushes the rotating rod 704, thereby driving the positioning cone 705 to insert into the fixing sleeve 604. When the plurality of positioning arc blocks 707 contact the corresponding limiting strips 605 (when the limiting strips 605 contact the center position 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 hand wheel 709 can be slowly turned left and right for positioning, so that the limiting strips 605 are aligned with the card slot 708), the positioning arc block 707 and the limiting strips 605 are in contact with each other. The contact surfaces of 5 are all conical, and they contact each other to realize automatic positioning, so that multiple limit strips 605 are inserted into the corresponding card slots 708. At this time, the hand wheel 709 is turned to drive the connecting sleeve 706 to rotate, thereby driving the fixing sleeve 604 to rotate, and then driving the threaded rod 602 to rotate, so that the extrusion plate 603 presses the adjustment seat 507 downward, so that the adjustment seat 507 presses the first spring 512, so that the compression elastic force of the first spring 512 becomes larger, and the opening pressure of the sealing block 503 is increased. Similarly, the threaded rod 602 rotates in the opposite direction to reduce the opening pressure of the sealing block 503. At this time, the alarm 43 will not sound an alarm; After the adjustment is completed, 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, the staff can 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 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.
