Problems solved by technology

[0002] In the current prior art, the opening and closing of the valves used in urban tap water pipelines, natural gas pipelines, and house tap water pipelines and natural gas pipelines is all by manual operation. When a pipe burst occurs, the valve cannot be automatically closed to cut off the water source and the gas source. This causes energy to be wasted, and causes floods and fires at the pipe burst site

Embodiment Construction

[0009] The basic principle of the squib self-closing valve of the present invention is to automatically judge and operate itself according to the comparison result of the measured flow velocity of the fluid flowing through it and the set flow velocity. The specific implementation method has multiple modes such as mechanical type and electric type. The electric type is to increase the electric detector, comparator and electric actuator on the basis of the mechanical type. What is described in the figure is a mechanical squib self-closing valve of the present invention. The valve plate has the function of measuring the flow rate and executing the closing function. The weight has the function of setting the flow rate. The set flow rate can be changed by increasing or decreasing the weight of the weight the size of. figure 1 , figure 2 , image 3 , Fig. 4 all do not indicate the connection mode of the size and the inlet and outlet pipes at both ends. This is because the pipe ...

Abstract

The invention discloses a pipe-explosion self-closing valve, which comprises the following parts: case, spool, valve plate and counterweight. The weight of counterweight can change the adjusting current velocity. When the fluid current velocity is not more than the adjusting current velocity, the pipe-explosion self-closing valve opens. When the fluid current velocity is more than the adjusting current velocity, the pipe-explosion self-closing valve closes automatically and keeps the closing state to avoid the energy waste and damage. When the exploded pipe is restored, the valve returns to the open state. When the main pipe appears the pipe-explosion phenomenon in the multi-source system, the invention can prevent reversing direction pipe-explosion from supplying energy.

Description

Technical field: [0001] The invention relates to a squib self-closing valve composed of a shell, a valve core, a valve plate and a French code. Background technique: [0002] In the current prior art, the opening and closing of the valves used in urban tap water pipelines, natural gas pipelines, and house tap water pipelines and natural gas pipelines is all by manual operation. When a pipe burst occurs, the valve cannot be automatically closed to cut off the water source and the gas source. Cause energy to be wasted, more cause flood, fire to burst tube place. Invention content: [0003] The task of the present invention is to provide a kind of squib self-closing valve, because this kind of squib self-closing valve can compare with the set flow rate according to the measurement result of the flow rate of fluids such as flowing through it tap water, natural gas, when it measures the actual When the flow rate is not greater than the set flow rate, the impulse force of the f...
