Description

Technical Field

[0001] The utility model relates to the technical field of fire valves, in particular to a fire valve with an anti-misoperation function. Background Technique

[0002] A fire valve is a valve used in a fire protection system. A fire protection system refers to activities and measures for preventing, controlling, and extinguishing fires to protect the safety of people and property, including fire prevention, fire fighting, and rescue operations. The common fire protection equipment is a fire valve, which is used to control the opening and closing and flow rate of the fire water flow. It is mainly used in the fire water pipe network to ensure that water sources can be provided in a timely and effective manner during a fire. Some fire valves are exposed and are easily misoperated by people, especially those holding tools, or other objects are installed on the switch of the fire valve, which is likely to cause water leakage or damage to the valve body and is inconvenient to use.

[0003] At present, the fire valves in use still have certain deficiencies. For example, the valve handle of the fire hydrant is easily misoperated by people, resulting in water leakage and spraying of the fire hydrant:

[0004] In order to overcome the misoperation of the valve handle of the fire hydrant, a Chinese patent of the prior art (publication number: CN215568358U) discloses an anti-misoperation fire hydrant valve handle. A rotating ring, a connecting rod, and a locking frame are arranged at the upper end of the fire hydrant main body. A locking component is arranged on the locking frame, so that the valve handle can be fixed by the locking frame during the non-use process, avoiding the situation that the water outlet of the fire hydrant main body sprays water or leaks water due to misoperation of the valve handle, resulting in waste or other accidents;

[0005] However, the fire valves currently in use still have certain deficiencies. In the above document, a rotating ring, a connecting rod, and a locking frame are arranged at the upper end of the fire hydrant main body, and the anti-misoperation is achieved by positioning the fire valve handle. However, the protection strength of the fire valve handle is limited. If the valve handle of the fire valve is accidentally collided by an object, the fire valve will not only leak water but may also be directly damaged, and the protection scenario is limited. Therefore, the existing structure needs to be improved. Content of the Utility Model

[0014] Furthermore, a clamping block is fixed at the top end of the push block. Clamping grooves are symmetrically opened at the left and right of the bottom of the rotating groove. The clamping block and the clamping groove are in clamping connection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0029] As Figures 1 - 3For the technical solution shown, the present invention provides the following technical solution: In order to solve the problem that the fire valve is not convenient to protect the valve switch 2, and it is easy to be damaged and leak water after being stressed, a protection mechanism is disclosed:

[0030] It includes a valve body 1, a valve switch 2 is connected to the top of the valve body 1, a connecting ring 201 is connected to the outside of the valve switch 2, and a protection mechanism for preventing the fire valve from being damaged by collision is arranged on the surface of the connecting ring 201. The protection mechanism includes a rotating groove 202, the rotating groove 202 is opened on the upper surface of the connecting ring 201, there are three groups of rotating grooves 202, a rotating rod 203 is rotatably connected inside the rotating groove 202, a through groove 211 is penetrated and opened on the upper surface of the valve switch 2, and a clamping mechanism for disassembling and assembling the protection mechanism is arranged inside the through groove 211. The protection mechanism also includes a threaded ring 204, the threaded ring 204 is threadedly connected to the side surface of the connecting ring 201, a T-shaped groove 205 is opened at the top of the threaded ring 204, a T-shaped block 206 is penetrated and rotated inside the T-shaped groove 205, and an extrusion ring 207 is fixed at the top of the T-shaped block 206. When the fire valve is not in use, rotating the threaded ring 204 can perform threaded sliding through the connecting ring 201. When the threaded ring 204 performs threaded sliding, it can push the extrusion ring 207 to move. When the extrusion ring 207 moves to the outer surface of the rotating rod 203, it can be extruded. When the rotating rod 203 is extruded, it can rotate through the rotating groove 202. At the same time, when the extrusion ring 207 is extruded, there will be a frictional force with the rotating rod 203. Through the frictional force, the extrusion ring 207 can be positioned. At this time, when the threaded ring 204 continues to rotate, it can drive the T-shaped groove 205 to rotate. When the T-shaped groove 205 rotates, it can rotate through the T-shaped block 206, so that the extrusion ring 207 can rotate out of sync with the threaded ring 204. When the extrusion ring 207 does not rotate, it can improve the stability of the extrusion of the rotating rod 203. After the three groups of rotating rods 203 are extruded to a certain position, they can form a circle. At this time, the three groups of rotating rods 203 can extrude each other to wrap the valve switch 2. After the valve switch 2 is wrapped, it will not be directly impacted by external forces, thereby avoiding the situation of water leakage or damage to the valve switch 2 after being stressed, and realizing the anti-misoperation function of the fire valve. Embodiment

[0031] As Figure 2 And Figure 4 For the technical solution shown, the present invention provides the following technical solution: In order to solve the problem that the protection effect of the protection mechanism of the fire valve may be insufficient, on the basis of Embodiment 1, a support mechanism is disclosed:

[0032] A support mechanism for improving the protection strength of the protection mechanism is provided on the side of the rotating rod 203. The support mechanism includes a rotating block 208, and the rotating block 208 is fixed inside the rotating rod 203. A support block 209 is rotatably connected inside the rotating block 208. A fixing block 210 is fixed on the upper surface of the connecting ring 201. There are three groups of fixing blocks 210 arranged around the center of the connecting ring 201. The fixing block 210 and the support block 209 are in positioning connection. When the protection mechanism of the fire valve is used, the extrusion ring 207 can push the rotating rod 203 to rotate. When the rotating rod 203 rotates, it can drive the support block 209 to rotate. Before the three rotating rods 203 form extrusion, they push the support block 209. When the support block 209 is pushed, it can rotate through the rotating block 208. After the support block 209 rotates to a specified angle, the rotating rod 203 continues to rotate. After the three rotating rods 203 form stable extrusion, the rotating rod 203 can drive the support block 209 to move into the groove of the fixing block 210 for extrusion. When the support block 209 is extruded, it can react on the rotating rod 203, so that the support block 209 can support the inside of the rotating rod 203. When supporting, the stability of the rotating rod 203 can be improved, and further the protection effect of the protection mechanism can be improved. Embodiment

[0033] As Figure 2 , Figure 5 and Figure 6 shown in the technical solution, the present invention provides the following technical solution: To solve the problems of troublesome installation and inconvenient use of the protection mechanism of the fire valve, a clamping mechanism is disclosed:

[0034] The engaging mechanism includes a spring 212. The spring 212 is connected inside the through groove 211. The end of the spring 212 is connected with a push block 213. The push block 213 slides through the inside of the through groove 211. A clamping block 214 is fixed at the top of the push block 213. Clamping grooves 215 are symmetrically formed at the left and right of the bottom of the rotating groove 202. The clamping block 214 is in clamping connection with the clamping groove 215. Positioning grooves 216 are symmetrically formed at the front and back of the bottom of the connecting ring 201. A positioning block 217 slides inside the positioning groove 216. The positioning block 217 is fixed on the upper surface of the valve switch 2. When the protection mechanism of the fire valve is in use, the push block 213 can slide through the through groove 211 by pressing. When the push block 213 slides, it can squeeze the spring 212. When the push block 213 is squeezed, it can drive the clamping block 214 to move. After the clamping block 214 is squeezed to a certain position, move the connecting ring 201 downward to the top of the valve switch 2. When the connecting ring 201 moves, it can slide through the surface of the valve switch 2. At the same time, when the connecting ring 201 moves, it can drive the clamping groove 215 and the positioning groove 216 to move. When the connecting ring 201 moves to the upper surface of the valve switch 2, the clamping block 214 can be inserted into the clamping groove 215. Release the push block 213, and it can be reset by the self-elastic force of the spring 212. When the push block 213 is reset, it can be clamped and positioned with the clamping block 214. When the clamping block 214 is positioned, it can drive the connecting ring 201 to be positioned up and down. At the same time, the positioning groove 216 can be inserted onto the surface of the positioning block 217 for horizontal positioning. Through the clamping block 214 and the positioning block 217, the connecting ring 201 and the valve switch 2 can be installed, improving the installation efficiency of the protection mechanism and the convenience of using the device.
