Description

Technical Field

[0001] The utility model relates to the technical field of marine fire valves, and particularly relates to a marine fire valve convenient for connecting water pipes. Background Technique

[0002] A marine fire valve is only an interface with a valve installed on the fire pipeline network inside a ship to supply water to a fire site. It belongs to a part of the ship's fixed fire-fighting equipment. Usually, it is installed in a fire hydrant box and used in conjunction with a fire hose and a fire nozzle to extinguish fires in buildings.

[0003] When the existing fire valve is connected to a water pipe, only the threads of the two are engaged with each other to connect the two. However, during use, due to the repeated shaking of the water pipe, the connection between the water pipe and the fire valve becomes loose, resulting in the problem of the water pipe falling off during use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a marine fire valve convenient for connecting water pipes to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A marine fire valve convenient for connecting water pipes includes a main body mechanism. Reinforcement mechanisms are fixedly connected to both ends of the main body mechanism, and a protection mechanism is fixedly connected to the main body mechanism.

[0007] The reinforcement mechanism includes a rubber pad. A reinforcement ring is fixedly connected to the rubber pad. Connecting holes are symmetrically opened on the reinforcement ring. A nut is fixedly connected to one side of the reinforcement ring, and a reinforcement bolt is inserted into the connecting hole.

[0008] The further improvement of the technical solution of the utility model is that the reinforcement bolt is threadedly connected to the inside of the nut. One end of the reinforcement bolt is fixedly connected to a pressing plate. During rotation, the pressing plate presses against one side of the reinforcement ring and, in cooperation with the nut, can reduce the size of the opening of the reinforcement ring.

[0009] The further improvement of the technical solution of the utility model is that the main body mechanism includes a valve body. An adjusting bolt is arranged on the top of the valve body. A connecting pipe is arranged on the valve body. Insert the water pipe into the connecting pipe, and then rotate the water pipe so that the threads on the surface of the water pipe are engaged with the connecting threads, and the water pipe can be connected to the connecting pipe.

[0010] The further improvement of the technical solution of the utility model is that connecting threads are arranged inside the connecting pipe. The rubber pad is fixedly connected to the outer wall of the connecting pipe. The rubber pad connects the connecting pipe and the reinforcement ring, and at the same time protects the outer wall of the connecting pipe, extending the service life of the connecting pipe.

[0011] A further improvement of the technical solution of the present utility model lies in that: the protection mechanism includes a buffer pad, the buffer pad is fixedly connected to the valve body, the inner wall of the buffer pad is fixedly connected with a support column, the support column is fixedly connected to the upper surface of the valve body, and the buffer pad can buffer the impact force, achieving the effect of protecting the adjusting bolt.

[0012] A further improvement of the technical solution of the present utility model lies in that: a sandwich layer is provided inside the support column, a limiting plate is movably connected inside the sandwich layer, and an extension plate is fixedly connected to the limiting plate. The sandwich layer is narrower at the top and wider at the bottom, so as to control the moving range of the limiting plate, thereby avoiding the phenomenon that the extension plate is separated from the support column.

[0013] A further improvement of the technical solution of the present utility model lies in that: the extension plate is movably connected inside the sandwich layer, and one end of the extension plate is fixedly connected to the lower surface of the adjusting bolt. When the adjusting bolt rotates, the extension plate can be driven to rotate inside the sandwich layer, and then the length of the extension plate exposed can be adjusted. Cooperating with the support column, it can protect the part of the adjusting bolt exposed, avoiding direct damage to the adjusting bolt by sundries.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] 1. The present utility model provides a marine fire valve convenient for connecting water pipes. Insert the reinforcing bolt into the connecting hole, rotate the pressing plate to drive the reinforcing bolt to rotate, and screw its tail end into the nut. During the rotation process, the pressing plate presses against one side of the reinforcing ring. Cooperating with the nut, it can reduce the size of the opening of the reinforcing ring, thereby reducing the circumference of the reinforcing ring, improving the tightness of the rubber pad fitting on the surface of the water pipe, and further improving the connection strength between the water pipe and the connecting pipe, avoiding the phenomenon of the water pipe falling off during use.

[0016] 2. The present utility model provides a marine fire valve convenient for connecting water pipes. When rotating the adjusting bolt, it can drive the extension plate and the limiting plate to rotate in the sandwich layer, so as to adjust the length of the extension plate exposed. Cooperating with the support column, it can protect the part of the adjusting bolt exposed, avoiding direct damage to the adjusting bolt by sundries. At the same time, the buffer pad can buffer the impact force, achieving the effect of protecting the adjusting bolt, thereby avoiding damage to the adjusting bolt by sundries and further extending the service life of the fire valve.

Rotate the adjusting bolt 22 to adjust the length of the adjusting bolt 22 protruding from the valve body 21, thereby adjusting the water flow rate.
