Description

Technical Field

[0001] The utility model relates to the technical field of spray valves, in particular to a connected spray valve. Background Art

[0002] The spray valve in the utility model is used in the field of fire extinguishing bottles. In the prior art, the structure and principle of the spray valve for the fire extinguishing agent to pass through the bottle may vary depending on the product model and manufacturer, but generally includes the following basic parts:

[0003] Structural part:

[0004] Valve body: The valve body is the main structural part of the blowdown valve, usually made of metal or plastic. It contains one or more channels that are responsible for controlling the flow of liquid or gas;

[0005] Spring: Springs are usually used to maintain the closed state of the valve body. When the user operates the blowdown valve, the spring may be compressed or stretched, thereby opening the valve body;

[0006] Valve core: The valve core is the moving part inside the valve body, usually connected to a spring. When the user presses or twists the spray valve, the valve core moves, thereby opening the valve body and allowing the fire extinguishing agent to flow out;

[0007] Trigger: The trigger is the part of the valve that the user interacts with, usually a button, lever, or other form of handle. Pressing or twisting the trigger initiates the opening of the valve.

[0008] Seals: To ensure that there is no leakage in the valve body when it is closed, the blow-off valve is usually equipped with seals, such as O-rings or other sealing devices.

[0009] Working principle of existing technology:

[0010] Closed state: Under normal circumstances, the valve body is in a closed state, and the spring prevents liquid or gas from flowing out by holding the valve core in the closed position;

[0011] User operation: When the user presses or twists the trigger of the spray valve, the movement of the trigger causes the valve core to move with the spring, opening the valve body;

[0012] Liquid or gas release: Once the valve body is opened, the fire extinguishing agent can be released into the external environment through the valve body channel. At this time, the liquid or gas can flow through the pipe to the nozzle and then spray into the target area;

[0013] Closing operation: After the user releases the trigger, the spring returns to its original state and pushes the valve core back to the closed position. This process ensures that the valve body can effectively close and stop the release of liquid or gas when the user is no longer operating.

[0014] From the above, it can be seen that the spray valve structure in the prior art requires manual control by the user during operation, and the spray function is relatively simple. During operation, manual control is time-consuming and labor-intensive, and the spray method is not efficient enough. For this reason, we have designed a connected spray valve to solve the above problems. Utility Model Content

[0044] It should be noted that installing two stainless steel storage bottles is only one of the implementation methods in this embodiment. The liquid inlet assembly includes at least one liquid inlet, which can enable the valve head body 1 to be connected to multiple fire extinguisher bottles at the same time. When spraying fire, the number of times the fire extinguisher bottles are replaced is reduced, the fire extinguishing capacity is greater, and the service life is longer.

[0045] In this embodiment, the valve head body 1 is installed on a frame between two stainless steel storage bottles, wherein the spray valve further includes a liquid inlet assembly 2, the liquid inlet assembly 2 includes two liquid inlets 201 installed on the sides of the valve head body 1, the two liquid inlets 201 are installed through the valve head body 1, and the two liquid inlets 201 are respectively connected to two stainless steel storage bottles as a fire extinguishing agent delivery source, and a delivery pipeline is connected between the outlets of the liquid inlet 201 and the stainless steel storage bottles;

[0049] A safety valve 6 is also installed on the valve head body 1. The safety valve 6 extends to the inside of the valve body and is connected to a safety diaphragm. When the pressure inside the swirl groove 7 is too high, it has a certain buffering effect on the pressure.

[0050] More specifically, refer to Figure 3 A piston 8 that can move up and down is installed in the valve head body 1 on one side of the external induction drive structure 402, and rubber sealing rings are installed at both upper and lower ends of the piston 8.

[0051] A swirl groove 7 is provided in the valve head body 1 between the electric drive structure 401 and the external induction drive structure 402, and a piston 8 extends into the swirl groove 7 of the valve head body 1 and is connected to a diaphragm pressure ring 4022, and a sealing diaphragm 4023 is installed inside the diaphragm pressure ring 4022;

[0052] In this embodiment, the electric drive structure 401 includes a needle-type electric explosion starter 4011 installed on the valve head body 1. The starting method of the needle-type electric explosion starter 4011 is DC24V electric starting. The tail end of the needle-type electric explosion starter 4011 is provided with a needle for piercing the sealing membrane 4023. When the needle-type electric explosion starter 4011 is started by DC24V electricity, the needle at the tail end will move downward to pierce the sealing membrane 4023.

[0053] More specifically, the electric starting method is: when a fire occurs, the DC24V of the electric drive structure 401 is started, and the needle of the electric needle type electric explosion starter 4011 is pushed upward to pierce the sealing membrane 4023 on the top of the piston 8. The stored fire extinguishing agent in the fire extinguishing agent bottle is released through the nitrogen in the bottle, along the delivery pipeline, through the sealing membrane 4023, and pushed into the action chamber of the atomizing nozzle 302 through the spray hole in the middle of the piston, and rotates at high speed along the vortex groove in the action chamber of the nozzle, and the liquid fire extinguishing agent is broken into micro water droplets with a diameter of 40μm~200μm and sprayed from the atomizing nozzle.

[0054] In this embodiment, the external induction driving structure 402 includes a temperature-sensitive glass ball 4021 , and the temperature-sensitive glass ball 4021 is installed on a side of the piston 8 close to the outside.

[0055] In this embodiment, the sealing diaphragm is fastened by the diaphragm pressure ring 9 at the end of the piston, and the temperature-sensitive glass ball 4021 is installed at the top of the piston. In this state, the valve is completely sealed.

[0058] A mounting hole matching the cone head is provided in the middle of one side of the piston 8 close to the outside. Under normal conditions, one end of the temperature-sensitive glass ball 4021 is installed in the mounting hole of the piston 8 through the cone head, and the other end of the temperature-sensitive glass ball 4021 is connected to the protective cover 5. The protective cover 5 can play a certain protective role after the temperature-sensitive glass ball 4021 breaks due to temperature sensing.

[0059] Temperature-sensing start mode: When encountering a fire, when the ambient temperature exceeds 68°C, the temperature-sensing glass ball 4021 on the top of the valve bursts, and the piston supported by the temperature-sensing glass ball loses its support. The pressure in the delivery pipeline pushes the piston away instantly, and the piston moves upward to open the spray hole. The fire extinguishing agent is pushed into the working chamber of the atomizing nozzle through the spray hole, and rotates at high speed along the swirl groove in the working chamber of the nozzle, tearing the liquid fire extinguishing agent into micro water droplets with a diameter of 40μm~200μm and spraying them out from the atomizing nozzle.
