Description

Technical Field

[0002] Fire sprinkler valves play a vital role in fire extinguishing systems, and their stability and reliability are crucial to protecting the lives and property of personnel. However, the current fire sprinkler valves have some technical challenges during long-term use, mainly focusing on the use of thermal springs to open and close the water outlet. At present, the opening and closing of the water outlet of fire sprinkler valves usually rely on thermal springs. Long-term water flushing and high temperature environment can easily cause spring aging, thereby affecting the normal operation of the sprinkler valve. Spring aging may cause the sprinkler valve to open or close untimely and inaccurately, and in severe cases may even cause the sprinkler valve to fail, thus affecting the normal operation of the fire protection system.

This design can ensure that the block can firmly seal the water outlet in a closed state to prevent water leakage and water pressure loss, thereby improving the sealing performance of the sprinkler valve.

This structural design enables the sprinkler valve to automatically open and close according to temperature changes, thereby simplifying the operating process and improving the response speed.

[0021] A thermal fire sprinkler valve comprises a sprinkler seat 1, a blocking block 2, a top piece 3 and a thermal spring 4, wherein the sprinkler seat 1 is provided with a water outlet 10, the blocking block 2 is penetrated in the water outlet 10 and seals the water outlet 10, the lower end of the sprinkler seat 1 is located at the lower side of the blocking block 2 and is provided with a top piece 3, one end of the thermal spring 4 is placed on the upper side of the top piece 3 and the other end is placed on the lower side of the blocking block 2, the inner wall of the water outlet 10 is located around the blocking block 2 and is also provided with an elastic pressing mechanism 5 for pressing the blocking block 2, by pressing the inner wall of the water outlet around the blocking block An elastic pressing mechanism for pressing the block is also provided on the side. This design can ensure that the block can firmly seal the water outlet in the closed state, prevent water leakage and water pressure loss, and improve the sealing performance of the nozzle valve. When the temperature rises, the characteristics of the thermistor spring will cause the block to rise, thereby opening the water outlet and opening the nozzle valve; when the temperature drops, the thermistor spring contracts, causing the block to drop, closing the water outlet and closing the nozzle valve. This structural design enables the nozzle valve to automatically open and close according to temperature changes, simplifies the operation process and improves the response speed.

[0022] Preferably, a groove 11 is provided on the inner wall of the water outlet 10 corresponding to the elastic clamping mechanism 5. The elastic clamping mechanism 5 can be inserted in the groove 11 and can reciprocate along the length direction of the groove 11. When the thermal spring 4 expands and squeezes the block 2, the block 2 moves upward along the inner wall of the water outlet 10 and pushes open the elastic clamping mechanism 5 to shrink into the groove 11, which can better control the opening and closing process of the nozzle valve and improve the stability and reliability of the system.

[0023] Preferably, the elastic clamping mechanism 5 includes a clamping block 50 placed on the side of the blocking block 2, and an elastic member 51 with one end placed in the groove 11 and the other end placed on the end of the clamping block 50 away from the blocking block 2. The elastic member 51 can provide elasticity for the reciprocating motion of the clamping block 50. The advantage of such a design is that in the process of the blocking block 2 moving upward to push the clamping block 50 open, the elastic member 51 can provide the required elastic support, thereby ensuring that the clamping block 50 can be reset and maintained in the appropriate position. This design can better control the movement of the block, improve the stability and reliability of the nozzle valve, and except for the clamping block, the pressure spring is located in the groove and is blocked by the clamping block and will not come into contact with water, reducing the possibility of aging.

[0025] Preferably, the inner wall of the water outlet 10 is located at the lower side of the groove 11 and extends toward the block 2 with a step surface 12, and the block 2 is mounted on the step surface 12 to block the water outlet 10. The block 2 can be firmly located on the step surface 12, thereby effectively blocking the water outlet 10 and improving the sealing performance of the nozzle valve. This structural design helps prevent water leakage and water pressure loss, and improves the reliability of the nozzle valve.

[0026] Preferably, an adjustment hole 13 is provided at the lower end of the nozzle seat 1 , and the top member 3 can be threadedly connected to the adjustment hole 13 .
