Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with leakage detection and alarm functions. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0004] However, after a long period of use, there is a risk of leakage in the valve. When the valve is in a position that is inconvenient for personnel to check, the leakage will be difficult to detect. Long-term leakage will cause certain dangers and losses. For this reason, a valve with leakage detection and alarm functions is proposed. Utility Model Content

[0005] 1. Technical Problems Solved

[0006] The technical problem to be solved by the utility model is that when the valve is located at a position which is inconvenient for personnel to check, leakage will be difficult to find.

[0007] 2. Technical Solution

[0008] In order to solve the above technical problems, the technical solution provided by the utility model is: a valve with leakage detection and alarm functions, including a valve body, an inlet pipe and a drain pipe are respectively installed on two opposite sides of the valve body, a water storage tank is provided on the lower inner wall of the drain pipe, a positive contact head is installed through the bottom of the water storage tank, a negative contact head is installed through the lower side wall of the drain pipe, the negative contact head is located on the side of the water storage tank away from the valve body, a frame is installed on the lower side of the drain pipe, a controller and a cable connector are installed inside the frame, the positive contact head and the negative contact head are respectively connected to the electrode connector through a wire, and a telescopic trigger button is installed through the bottom of the valve body.

[0009] As an improvement, the controller is connected to the electrode connector via a signal line, and the telescopic trigger button is connected to the controller via the signal line.

[0010] As an improvement, a guide hole is provided at the lower portion of the side wall of the frame body for passing the signal line between the telescopic trigger button and the controller.

[0011] As an improvement, an alarm light is installed outside the frame.

[0012] As an improvement, a moisture-proof plate is installed inside the frame, and the controller and the electrode connector are respectively installed on the lower side of the moisture-proof plate.

[0014] As an improvement, threaded sleeves are respectively provided on opposite sides of the valve body, and the water inlet pipe and the drain pipe are respectively installed inside the threaded sleeves by means of threads.

[0015] 3. Beneficial Effects

[0016] Compared with the prior art, the advantages of the utility model are: when the valve body is closed, the telescopic trigger button is pressed and triggered, and the fluid leaking from the valve body is collected by the water storage tank. When the fluid flows into the drain pipe, the positive contact head and the negative contact head contact the fluid to form a closed-loop circuit. The telescopic trigger button and the electrode connector simultaneously transmit signals to the controller, which is determined to be a fluid leakage. The controller promptly sends information to the control terminal, so that the leakage of the valve that is inconvenient to check can be quickly grasped and maintained.

[0024] As attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, a valve with leakage detection and alarm functions includes a valve body 1, a water inlet pipe 3 and a drain pipe 4 are respectively installed on opposite sides of the valve body 1, a water storage tank 5 is provided on the inner wall of the lower side of the drain pipe 4, a positive contact head 6 is installed through the bottom of the water storage tank 5, a negative contact head 7 is installed through the lower side wall of the drain pipe 4, and the negative contact head 7 is located on the side of the water storage tank 5 away from the valve body 1, a frame 8 is installed on the lower side of the drain pipe 4, a controller 10 and an electrode connector 11 are installed inside the frame 8, an alarm light 12 is installed on the outside of the frame 8, and a telescopic trigger button 13 is installed through the bottom of the valve body 1.

[0025] Through the above structure, when the valve body 1 is closed, the telescopic trigger button 13 is pressed downward to transmit a signal to the controller 10. After the positive contact head 6 at the bottom of the water storage tank 5 and the negative contact head 7 on the lower side wall of the drain pipe 4 contact the fluid at the same time, a conductive loop is formed with the electrode connector 11. The electrode connector 11 transmits the signal to the controller 10, and the controller 10 sends a signal to the control terminal, and the controller 10 lights up the alarm light 12, which is convenient for the staff to quickly find the valve with a leak. The specific structure is as follows:

[0027] Through the above structure, the electrode connector 11 is installed between the positive contact head 6 and the negative contact head 7 through a wire, and the telescopic trigger button 13 and the electrode connector 11 both transmit signals to the controller 10 through the signal line. The signal line connected to the telescopic trigger button 13 passes through the guide hole 14 to the inside of the frame 8 and is connected to the controller 10.

[0033] The specific method of use is as follows: when the valve body 1 is closed, press the telescopic trigger button 13 downward to trigger the telescopic trigger button 13. When the valve body 1 leaks, the water storage tank 5 collects the fluid leaked from the valve body 1. When a large amount of fluid leaks and flows into the drain pipe 4, the positive contact head 6 and the negative contact head 7 contact the fluid and form a closed-loop circuit with the electrode connector 11. The telescopic trigger button 13 and the electrode connector 11 simultaneously transmit signals to the controller 10, which is determined to be a fluid leakage, and the information is sent to the control terminal in a timely manner through the controller 10.
