[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a safety protection valve for an organic heat carrier heating furnace, which has the following beneficial effects:
[0015] (1) This utility model is provided with a valve body, an organic heat carrier heater safety pipe and a conical plug. The organic heat carrier heater safety pipe can be connected to the organic heat carrier heater for discharging excessively high-pressure steam. The valve body can be fixed to the organic heat carrier heater safety pipe by flange and fixing bolts. The sealing ring installed on the valve body can be correspondingly embedded in the sealing groove opened on the organic heat carrier heater safety pipe to improve the sealing effect and prevent steam leakage. An outer protective shell is fixedly installed on the outside of the valve body, and a nut is fixedly installed in the center of the top surface of the outer protective shell. An adjusting threaded rod shaft is screwed into the nut. An installation plate is provided in the inner cavity of the outer protective shell, and a connecting shaft seat is installed in the center of the top surface of the installation plate. The bottom end of the adjusting threaded rod shaft is installed in the connecting shaft seat. A first guide slide rod is symmetrically fixedly installed on the top surface of the installation plate. A first guide sleeve is symmetrically fixedly installed on the outer protective shell, and a first guide slide rod is sleeved inside the first guide sleeve. Several pressure springs are evenly installed on the bottom surface of the installation plate. A conical plug is connected and installed at the bottom, and a second guide slide rod is symmetrically fixedly installed on the top surface of the conical plug. A second guide sleeve is symmetrically fixedly installed on the mounting plate, and a second guide slide rod is sleeved inside the second guide sleeve. A conical exhaust port is opened in the center of the top surface of the valve body. The conical plug seals the conical exhaust port. By rotating the adjusting threaded rod shaft, the mounting plate can be pushed to move along the direction of the first guide slide rod, thereby compressing the pressure spring between the mounting plate and the conical plug more forcefully, thus increasing the pressure of the conical plug sealing the conical exhaust port. When the steam pressure inside the organic heat carrier heater is too high, the steam can enter the valve body through the safety pipe and then push the conical block upwards. As the pressure spring is further compressed, the conical block slides along the direction of the second guide slide rod, and the steam can be discharged through the conical exhaust port, thus achieving safe pressure relief. The safety valve of this organic heat carrier heater allows users to quickly adjust the sealing pressure of the conical block to adapt to different models of organic heat carrier heaters, making adjustment and use more convenient and practical.
[0016] (2) This utility model is provided with an outer protective shell, a pre-cooling box, heat exchange pipes and safety vent holes. The pre-cooling box is fixedly installed in the inner cavity of the outer protective shell. One side of the inner cavity of the pre-cooling box is connected to an inlet pipe and the other side is connected to an outlet pipe. A coolant circulation mechanism can be connected to the inlet and outlet pipes to allow the coolant to circulate through the inner cavity of the pre-cooling box. Several heat exchange pipes are evenly fixedly installed on the pre-cooling box. Several safety vent holes are evenly opened at the bottom of the side wall of the outer protective shell. As mentioned above, the steam discharged from the pressure relief will enter the inner cavity of the outer protective shell. The high-temperature steam will pass through the heat exchange pipes and exchange heat with the coolant when passing through the heat exchange pipes, thereby quickly reducing the temperature of the discharged steam to a certain extent. The cooled steam is then finally discharged through the safety vent holes, making the steam discharge of the safety protection valve of the organic heat carrier heater safer, preventing accidental burns to surrounding personnel, making it safer to use and more practical.

[0032] In one embodiment, the precooling box 3 has an annular cross-sectional shape.
[0033] Working Principle: This utility model includes a valve body 1, an organic heat carrier heater safety pipe 9, and a conical plug 7. The organic heat carrier heater safety pipe 9 can be connected to the organic heat carrier heater for discharging excessively high-pressure steam. The valve body 1 can be fixed to the organic heat carrier heater safety pipe 9 via flanges and fixing bolts. The sealing ring 22 installed on the valve body 1 can be correspondingly fitted into the sealing groove 21 opened on the organic heat carrier heater safety pipe 9 to improve the sealing effect and prevent steam leakage. An outer protective shell 6 is fixedly installed on the outside of the valve body 1, and a nut 11 is fixedly installed in the center of the top surface of the outer protective shell 6. An adjusting threaded rod is screwed into the nut 11. Shaft 10 has an outer protective shell 6 with an inner cavity containing a mounting plate 14. A connecting shaft seat 12 is mounted at the center of the top surface of the mounting plate 14. The bottom end of the adjusting threaded rod shaft 10 is installed inside the connecting shaft seat 12. A first guide slide rod 5 is symmetrically fixedly mounted on the top surface of the mounting plate 14. A first guide sleeve 13 is symmetrically fixedly mounted on the outer protective shell 6, and the first guide slide rod 5 is sleeved inside the first guide sleeve 13. Several pressure springs 15 are evenly mounted on the bottom surface of the mounting plate 14, and a conical block 7 is connected to the bottom end of each pressure spring 15. A second guide slide rod 16 is symmetrically fixedly mounted on the top surface of the conical block 7. A second guide sleeve 17 is symmetrically fixedly mounted on the mounting plate 14, and a second guide slide rod 16 is sleeved inside the second guide sleeve 17. The second guide slide rod 16 has a conical exhaust port 18 at the center of the top surface of the valve body 1. A conical block 7 is installed inside the conical exhaust port 18. By rotating the adjusting threaded rod shaft 10, the mounting plate 14 can be moved along the direction of the first guide slide rod 5, thereby compressing the pressure spring 15 between the mounting plate 14 and the conical block 7 more forcefully, which in turn increases the pressure of the conical block 7 sealing the conical exhaust port 18. When the steam pressure inside the organic heat carrier heater is too high, steam can enter the inner cavity of the valve body 1 through the organic heat carrier heater safety pipe 9, and then push the conical block 7 upward. As the pressure spring 15 is further compressed, the conical block 7 slides along the direction of the second guide slide rod 16, and steam can then pass through the conical exhaust port 18. The safety valve of this organic heat carrier heater allows users to quickly adjust the sealing pressure of the conical plug 7 to adapt to different models of organic heat carrier heaters, making adjustment and use more convenient and practical. Additionally, this invention includes an outer protective shell 6, a pre-cooling box 3, heat exchange pipes 19, and a safety vent 20. The pre-cooling box 3 is fixedly installed inside the outer protective shell 6, with an inlet pipe 2 connected to one side of the pre-cooling box 3 and an outlet pipe 8 connected to the other side. A coolant circulation mechanism can be connected externally through the inlet pipe 2 and outlet pipe 8, allowing coolant to circulate through the pre-cooling box 3. Several heat exchange pipes 19 are evenly fixedly installed on the pre-cooling box 3.The outer protective shell 6 has several safety vent holes 20 evenly distributed at the bottom of its side wall. As described above, the steam released during pressure relief enters the inner cavity of the outer protective shell 6. The high-temperature steam then passes through the heat exchange pipe 19, where it exchanges heat with the coolant, thus rapidly reducing the temperature of the discharged steam to a certain extent. The cooled steam is then finally discharged through the safety vent holes 20, making the steam discharge from the safety valve of the organic heat carrier heater safer, preventing accidental burns to surrounding personnel, and enhancing its safety and practicality.
