Problems solved by technology

At present, the closing pressure of the existing squib shut-off valve is factory-set, but the medium pressure in the pipeline is variable and uncontrollable, so the existing squib shut-off valve has poor adjustability and reliability. It is relatively low, prone to failures, and it may happen that the burst pipe shut-off valve fails to close in time; it may also occur that the valve is closed without bursting the pipe

Embodiment Construction

[0023] Combine below Figures 1 to 3 The structure and invention of the squib shut-off valve of the present invention are described.

[0024] Such as figure 1 As shown, a squib shut-off valve includes a valve body 1, a water inlet channel 2 and an outlet channel 3 arranged at both ends of the valve body 1, a support plate 4 respectively arranged in the water inlet channel 2 and the water outlet channel 3, and a The valve disc 5 inside the valve body 1 , the driving mechanism arranged at both ends of the valve disc 5 and controlling the opening and closing of the valve disc 5 , the valve seat 6 sealingly matched with the valve disc 5 and the sealing ring 7 installed on the valve seat 6 . The valve seats 6 are respectively arranged on the water inlet channel 2 and the water outlet channel 3 to cooperate with the valve disc 5 .

[0025] The valve body 1 is symmetrically arranged in two identical structures and fixedly connected by several bolts.

[0026] Both the water inlet c...

Abstract

The invention provides a squib shut-off valve, which includes a valve body, a water inlet channel and a water outlet channel, a valve flap arranged inside the valve body, and a driving mechanism arranged at both ends of the valve flap, and each driving mechanism includes a valve connected to the valve flap. The cylinder body, the piston installed in the cylinder body and the control pilot valve connected with the cylinder body, the control pilot valve includes the pilot valve body installed on the valve body, the water inlet, the water outlet and the water outlet connected to the cylinder body A plurality of communication ports connected, a regulating valve installed on the water outlet to control the on-off of the water outlet, a needle valve installed on each communication port, and a plug movably installed at the water inlet, the water inlet communicates with the communication port, The valve disc is in contact with the piston. The present invention uses the entire valve disc as a medium for inductive flow velocity change, amplifies the change characteristics of the medium flow velocity and converts it into a pressure signal, and senses the characteristics of the pipe burst through the transformed pressure change. Such a sensing method The sensitivity is high, the reliability is high, and the response condition of the squib closing is sufficiently reliable.

Description

technical field [0001] The invention relates to the field of valves, in particular to a squib shut-off valve. Background technique [0002] Due to the long water supply pipeline of the urban water supply project, when a pipe burst occurs in the pipeline, the on-duty personnel should inspect the site. would lead to increased losses. The squib shut-off valve is installed on the main water delivery pipe. Under normal conditions, the squib shut-off valve is open; when a squib accident occurs in the pipeline, the squib shut-off valve is automatically closed to cut off the squib pipeline to prevent the loss of the squib. expansion. At present, the closing pressure of the existing squib shut-off valve is factory-set, but the medium pressure in the pipeline is variable and uncontrollable, so the existing squib shut-off valve has poor adjustability and reliability. If it is relatively low, it is prone to failure. It may happen that the burst pipe shut-off valve fails to close in t...
