Description

Technical Field

[0001] The utility model relates to the technical field of valve state detection, in particular to a valve opening and closing judgment device. Background Art

[0002] Valves are pipe accessories used to open and close pipes, 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. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] However, when the existing valves are in use, the screw rods of valves installed outdoors often fall off after long-term use. When the valve is opened or closed, the valve plate does not move, and it is impossible to determine whether the valve is open or closed. In this case, the valve can generally be manually turned to observe its opening and closing conditions, or different electrical signals can be applied to the electric control valve to observe its action conditions, so as to determine whether the valve is flexible, free of obstruction, leakage, etc. In addition, the electric control valve can be installed in the actual working environment for long-term operation test to check its stability, accuracy and reliability.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a valve opening and closing judgment device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a valve opening and closing judgment device to solve the problem that the judgment of whether the valve is opened or closed is complicated and inaccurate in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve opening and closing judgment device, comprising a valve body, a connecting pipe is installed at the end of the valve body through a flange, a delivery pipeline is installed on the top of the connecting pipe, a high-pressure hand valve is arranged on the outer wall of the delivery pipeline, a high-pressure check valve located on one side of the high-pressure hand valve is arranged on the outer wall of the delivery pipeline, a flow switch located on one side of the high-pressure check valve is arranged on the outer wall of the delivery pipeline, and a delivery groove is arranged on the inner wall of the delivery pipeline.

[0007] Furthermore, the specific model of the high-pressure hand valve is KHM--F--X.

[0008] Furthermore, the central axis of the high-pressure hand valve, the central axis of the high-pressure one-way valve, and the central axis of the flow switch are arranged to overlap with each other.

[0009] Furthermore, the specific model of the flow switch is RHK.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model provides a delivery pipeline. When the valve is used in daily life, the delivery pipeline can be installed at the rear end of the valve outlet which is easy to be damaged. When the valve body is opened, the high-pressure hand valve is opened through the connection of the connecting pipe, so that the liquid flow is delivered to the inner wall of the delivery pipeline. When the liquid flow delivered to the delivery pipeline reaches a certain pressure, the one-way valve can be opened, and the flow switch detects the water flow from left to right. The valve is closed or the valve is not fully opened, the pipeline pressure is insufficient, the one-way valve cannot be opened, and the flow switch cannot detect the water flow, which plays a role in efficiently judging and detecting the opening and closing state of the valve.
