Problems solved by technology
[0004] This technical solution can realize the rapid closing of the gas valve; however, when closing the valve, one person needs to pull the valve handle forcefully, and another person pulls out the bolt pin, so it is very inconvenient to operate by one person, and the operation is not very fast; the valve The size of the opened opening cannot be adjusted at will; the operation is also complicated when opening the valve, and the efficiency is not high

Embodiment approach
[0026] As an embodiment of the present invention, the first cylindrical cavity 33 of the valve rod 3 is fixedly connected to the inner wall of one end of the installation block 37; the center of one end of the installation block 37 is fixedly connected to one end of the first telescopic rod 38; The other end of the No. 1 telescopic rod 38 is fixedly connected to the pressure block 39, and a No. 2 spring 40 is respectively provided on both sides of the No. 1 telescopic rod 38; one end of the No. 2 spring 40 is connected to the end face of the mounting block 37, and the other end of the No. 2 spring 40 is connected to Press block 39; when working, when the valve is closed, under the action of the elastic force of No. 1 spring 4, the valve core 2 drives the valve stem 3 to move, and the valve stem 3 drives the press block 39 to move through the installation block 37. When the press block 39 touches the sliding When the other end of the telescopic rod 9 outside the shaft 8, the pre...

The invention belongs to the technical field of valves, and particularly relates to an industrial rapid gas valve. The industrial rapid gas valve comprises swing handles, tooth-shaped plates, springs,a fixed shaft, a sliding shaft and telescopic rods; the corners of the swing handles are hinged to the side wall of a first rectangular groove, one ends of the swing handles are arranged in kidney holes in one ends of the tooth-shaped plates in a sliding manner, the other ends of the tooth-shaped plates are hinged through the fixed shaft, the two ends of the fixed shaft are fixedly connected to the inner wall of a first cylindrical cavity of a valve rod, one end of a fourth rectangular groove is hinged to one ends of the telescopic rods, the other ends of the two telescopic rods are hinged through the sliding shaft, and the sliding shaft is clamped between arc teeth of the two tooth-shaped plates. The sliding shaft is arranged between the arc teeth of the two tooth-shaped plates, the swing handles are used for driving the tooth-shaped plates to swing, rapid opening or closing of the gas valve is achieved only by pulling the swing handles, operation is easy, and time and labor are saved.
Description
technical field [0001] The invention belongs to the technical field of valves, in particular to an industrial fast gas valve. Background technique [0002] In the existing technical field of gas valves, the closing of the valve depends on the rotation of the valve stem to push the valve core to move up and down to realize the closing of the valve, but the linear movement speed of the threaded rotation of the valve stem is slow, especially when the valve is in an emergency state from the open state to the closed state. state, the action time is long, and it cannot meet the requirements of quickly cutting off the gas source. [0003] There have also been some technical solutions for fast gas valves in the prior art. For example, a Chinese patent with application number 201010260401.2 discloses a fast gas valve, including: a valve body, a disc, a valve cover, a spring, and a valve stem. A fast gas valve stem is provided with a hole perpendicular to the axis of the valve stem, ...
