Description

Technical Field

[0001] The utility model relates to the field of fire extinguishers, and more specifically, to a fire extinguisher valve structure. Background Art

[0002] The fire extinguisher valve is mainly used to control its open and closed state, so that the fire extinguisher can achieve good performance when it is in use or not in use. It is an indispensable main accessory of the fire extinguisher.

[0003] Traditional fire extinguisher valves are basically push-type, and the springs on the valves are usually installed naked inside. When fire extinguishing is needed, the fire extinguishing medium in the fire extinguisher tank needs to pass through the spring when spraying out, and a large amount of fire extinguishing medium will adhere to the spring. After the fire extinguisher is used in cycles for many times, the filled fire extinguishing medium is easy to corrode the spring and affect the performance of the spring. When used in an emergency, the spring is prone to loss of elasticity, deformation or breakage, affecting the service life and performance of the fire extinguisher. Utility Model Content

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-4 A fire extinguisher valve structure comprises a valve body 1, a pressure handle 2 is arranged at the top of the valve body 1, a safety pin 3 is arranged at the side wall of the pressure handle 2, an upper connecting pipe 4 is fixedly connected to the side wall of the valve body 1, a lower connecting pipe 5 is fixedly connected to the bottom end of the valve body 1, a control chamber 6 is opened in the valve body 1, a sealing plug 7 is arranged in the control chamber 6, a pressure rod 8 is fixedly connected to the top of the sealing plug 7, the top of the pressure rod 8 is against the pressure handle 2, a protection component is arranged in the control chamber 6, an adjusting component is arranged near the upper connecting pipe 4 in the inner cavity of the valve body 1, a guide block 17 is fixedly connected near the upper connecting pipe 4 in the inner cavity of the valve body 1, and the cross section of the guide block 17 is arranged in an arc shape, which can increase the smoothness of the fire extinguishing medium when it is sprayed.

[0027] See also Figure 2 and Figure 3 The protection component includes several cylinders 9, which are located in the control chamber 6. A movable rod 10 is movably connected inside the cylinder 9. The top of the movable rod 10 is fixedly connected to the sealing plug 7. A spring 11 is fixedly connected between the bottom end of the movable rod 10 and the cylinder 9. A sealing ring 12 is fixedly connected to the side wall of the movable rod 10 near the bottom end. The sealing ring 12 is against the inner wall of the cylinder 9, which can increase the sealing performance of the movable rod 10 and the cylinder 9.

[0028] By the mutual cooperation among the valve body 1, the sealing plug 7 and the protective component, the spring 11 is sealed in the cylinder 9, which can effectively solve the problem of the spring 11 being exposed. When used in conjunction with the sealing ring 12, the fire extinguishing medium can be effectively prevented from contacting the spring 11. After multiple cycles of use, the fire extinguishing medium adhering to the spring 11 is likely to corrode the spring 11 and affect the performance of the spring 11, thereby ensuring the stability of the fire extinguisher.

[0029] See also Figure 2 and Figure 4The adjusting component includes a baffle 13, which is located in the inner cavity of the valve body 1. The side wall of the upper connecting pipe 4 is threadedly connected with a screw 14. The bottom end of the screw 14 is rotatably connected to the baffle 13, and the top of the screw 14 is fixedly connected with a rotating rod 15. The inner wall of the upper connecting pipe 4 is provided with a groove 16. The baffle 13 is located in the groove 16, which can both limit the baffle 13 and store the baffle 13. Through the mutual cooperation between the valve body 1, the upper connecting pipe 4 and the adjusting component, the injection pressure of the fire extinguisher can be adjusted according to actual conditions, so that the rescue personnel can reach a certain safe distance from the fire source, avoiding the danger of burns to the rescue personnel, and greatly improving the safety of the use of the fire extinguisher.

[0030] During use: when it is necessary to adjust the injection pressure of the upper connecting pipe 4, the rotating rod 15 can be rotated to drive the screw 14 to rotate, and the screw 14 drives the baffle 13 to move downward. The gap between the baffle 13 and the inner cavity of the valve body 1 can be used to control the injection impact force of the fire extinguishing medium. It can be adjusted on-site according to the fire source situation to increase the safety of the fire extinguisher. When injecting the fire extinguishing medium, the pressure handle 2 can be pressed to drive the pressure rod 8 to move downward, and the pressure rod 8 drives the sealing plug 7 to move downward, connecting the control chamber 6 with the inner cavity of the valve body 1, and the fire extinguishing medium is injected. Since the spring 11 is located in the cylinder 9 and is in a sealed state, the spring 11 will not be corroded by the fire extinguishing medium, thereby reducing the probability of damage to the valve and extending the number of cycles of the fire extinguisher.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
