Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically to an inlet valve for a pulse air pressure spray water gun. Background Technology

[0002] The fire extinguishing principle of a pulse air pressure spray water gun is to use compressed air as power, which is sprayed out by the ultra-fast opening exhaust valve in a very short time. This propels the fire extinguishing agent in the water tank and launches it out at extremely high speed. The friction and collision between air and liquid molecules produce atomized liquid particles. These particles have great kinetic energy and can penetrate the flames and rising airflow, directly hitting the fire. After the liquid particles vaporize, the flame temperature drops rapidly, achieving the purpose of extinguishing the fire. Pulse air pressure spray water guns are characterized by rapid operation and deployment, water saving and high efficiency, environmental protection and high mobility. No additional power supply is required during use. Various fire extinguishing additives can be used as needed. They are easy to use and maintain. The water inlet valve is an important component of the pulse air pressure spray water gun.

[0003] While the machining of some parts of the pulse air pressure spray water gun inlet valve is not difficult, it is still relatively material-intensive and time-consuming. The inlet valve body rod is made of stainless steel, which is difficult to machine due to its many holes. The inlet sleeve is made of aluminum, which requires external machining for surface oxidation, which takes even longer. This significantly increases the production cost of the pulse air pressure spray water gun inlet valve. Therefore, those skilled in the art have provided an inlet valve for pulse air pressure spray water guns to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an inlet valve for a pulse air pressure spray water gun to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pulse air pressure spray water gun inlet valve includes an inlet main valve body, which includes an inlet pipe, a ball valve, and an outlet pipe. The left side of the ball valve is connected to the inlet pipe. A connecting ring is installed on the outer surface of the ball valve. The inner wall of the connecting ring is threaded to the outlet pipe. An outlet head is installed on the outer surface of the outlet pipe. The ball valve includes a valve core. A valve stem is installed on the outer surface of the valve core. A handle is installed at the top of the valve stem.

[0007] As a further improvement of this utility model: a first sealing ring is installed on the outer surface of the valve stem, and a sealing gasket is fixedly connected to the outer surface of the valve core.

[0008] As a further improvement of this utility model: a second sealing ring is installed on the inner wall of the water inlet pipe, and an installation groove is provided on the outer surface of the water inlet pipe.

[0009] As a further improvement of this utility model: an O-ring is installed inside the water inlet pipe, and the O-ring is made of rubber.

[0010] As a further improvement of this utility model: the outer surface of the water outlet pipe is equipped with a reinforcing angle, and the outer surface of the main water inlet valve body is coated with anti-corrosion paint.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figures 1-3 In this embodiment of the invention, an inlet valve for a pulse air pressure spray water gun includes an inlet main valve body 1. The inlet main valve body 1 includes an inlet pipe 2, a ball valve 3, and an outlet pipe 5. The left side of the ball valve 3 is connected to the inlet pipe 2. A connecting ring 4 is installed on the outer surface of the ball valve 3. The inner wall of the connecting ring 4 is threadedly connected to the outlet pipe 5. An outlet head 6 is installed on the outer surface of the outlet pipe 5. The ball valve 3 includes a valve core 8. A valve stem 9 is installed on the outer surface of the valve core 8. A handle 10 is installed at the top of the valve stem 9. A ball valve that is readily available on the market can be used by removing the inlet valve body stem and making a connector to connect to the ball valve. The same effect can be achieved by simply applying the valve body to the valve body. This saves on raw materials and processing costs, eliminates the need for external oxidation processing of the valve sleeve, and saves a lot of money. It also reduces the processing cycle and solves the problem mentioned in the background technology that although the processing of some parts of the pulse air pressure spray water gun inlet valve is not difficult, it is still relatively material-intensive and time-consuming. The inlet valve body rod is made of stainless steel and is difficult to process due to its many holes. The inlet sleeve is made of aluminum and requires external oxidation processing, which takes even longer. This significantly increases the production cost of the pulse air pressure spray water gun inlet valve.

[0020] A first sealing ring 11 is installed on the outer surface of the valve stem 9, a sealing gasket 12 is fixedly connected to the outer surface of the valve core 8, a second sealing ring 13 is installed on the inner wall of the water inlet pipe 2, and an installation groove 14 is opened on the outer surface of the water inlet pipe 2. This not only makes it convenient for people to connect and install the water inlet main valve body 1, but also makes the sealing effect of the water inlet main valve body 1 better.

[0021] The inlet pipe 2 is equipped with an O-ring 15 made of rubber. The outlet pipe 5 is equipped with a reinforcing angle 7 on its outer surface. The outer surface of the main inlet valve body 1 is coated with anti-corrosion paint, which not only makes the main inlet valve body 1 corrosion resistant, but also greatly increases the strength of the outlet pipe 5.

[0022] The working principle of this utility model is as follows: First, the main inlet valve body 1 can be connected to the pipeline. The ball valve 3 is set to prevent the inlet valve from being too expensive to process due to the high material consumption and long processing time. The inlet valve body rod is made of stainless steel, which is difficult to process due to the many holes. The inlet sleeve is made of aluminum, which requires external processing and takes longer. The first sealing ring 11, the second sealing ring 13, the O-ring 15 and the sealing gasket 12 can prevent leakage at the connection of the main inlet valve body 1.

[0023] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto.
