Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] According to one aspect of the present invention, there is provided a control valve, such as figure 1 and 2 As shown, the control valve includes: a cut-off valve 10; a flow detection device 20, which is used to detect the flow in the pipeline controlled by the cut-off valve 10, and send a flow signal; The flow signal sent by the device controls the shut-off valve 10 to close.

[0024] The control valve of the present invention detects the flow rate in the valve body or in the pipeline provided by the control valve through the flow detection device 20, and controls the shut-off valve 10 to close according to the flow rate to cut off the pipeline, thereby realizing real-time monitoring a...

Abstract

The invention provides a control valve and a fluid system. The control valve comprises an intercepting valve, a flow detection device and a control part. The flow detection device is used for detecting the flow in a pipeline controlled by the intercepting valve and sending out a flow signal. The control part is electrically connected with the flow detection device and controls the intercepting valve to be turned off according to the flow signal sent out by the flow detection device. By the adoption of the technical scheme of the control valve, the flow in a valve body or the flow in the pipeline provided with the control valve is detected through the flow detection device, the intercepting valve is controlled to be turned off according to the flow to intercept the pipeline, and real-time monitoring and quick response treatment of the pipeline leakage fault are achieved.

Description

technical field [0001] The invention relates to the field of fluid equipment, in particular to a control valve and a fluid system. Background technique [0002] In the power supply system, the application of automation equipment is becoming more and more extensive, and the degree of automation is getting higher and higher, and many sites have been unmanned. [0003] However, the water supply pipelines in some sites are aging, and failures such as running, running, dripping, and leaking may occur. If pipeline failures occur in unmanned sites, such failures are difficult to be monitored, and in severe cases, equipment will be soaked in water. [0004] The existing solution is to regularly inspect the site, such as once a month, and compare the readings of the water meter. If the readings increase significantly, there may be a pipeline failure that has caused water leakage. In addition, if water marks or accumulated water are found during the inspection process, it can also be...
