Problems solved by technology

[0003] The present invention overcomes the deficiencies of the prior art and provides an instantaneously positioned air valve. The starting section of the thread lift angle on the large gear shifting screw rod remains unchanged, and the transition section and the rising section change from a small angle to a large angle, so that when the valve is closed, Instantaneous closing is achieved, which solves the problems of long closing time and high energy consumption of general air valves

Embodiment 1

[0026] Such as Figure 1-4 As shown, the present invention comprises large gear shifting type screw rod 4 and common parts for positioning air valves. The helical patterns on the large gear shifting type screw rod 4 are divided into starting section, transition section and rising section, and the starting section thread lead angle is different. The thread lead angles of the starting section, the transition section and the rising section increase sequentially, and the starting section, the transition section and the rising section are connected smoothly in sequence.

[0027] At present, there are three mainstream air valves in China: clutch air valves, turbine air valves and screw air valves.

[0028] The operating voltage range of the first clutch valve is between 4.5V-6.5V, the valve opening time is greater than 1.5 seconds, the valve closing time is 0.3 seconds, the energy storage capacitor is 3300 microfarads / 10 volts, the valve closing time is fast and the energy storage ...

Embodiment 2

[0033] In this embodiment, on the basis of Embodiment 1, the preferred specific structure is as follows: the change rate of the thread lead angle in the transition section is smaller than the change rate of the thread lead angle in the ascending section. Realize a smooth transition, let the rising section realize a steeper rapid rise, and achieve the purpose of shortening the length of the spiral rising section.

Embodiment 3

[0035] In this embodiment, on the basis of any one of the above embodiments, the preferred specific structure is as follows: the number of turns of the helical pattern on the large gear shifting screw rod 4 is 1 turn. In this device, the lifting height of the upper helix of the large gear shifting type helical rod is 12 mm, and one turn of the helix is ​​the optimal number of turns to reduce the time for opening and closing the valve.

Abstract

The invention discloses a gas valve with an instant positioning effect. The gas valve comprises a large-gearwheel displacement-variable spiral bar. Spiral threads on the large-gearwheel displacement-variable spiral bar are divided into a starting section, a transition section and a rising section, a rising angle of the threads of the starting section is unchanged or is gradually increased with the increase amplitude smaller than 2 degrees, rising angles of the threads of the starting section, the transition section and the rising section are gradually increased, and the starting section, the transition section and the rising section are sequentially and smoothly connected with one another. The gas valve with the structure has the advantages that the rising angle of the threads of the starting section on the large-gearwheel displacement-variable spiral bar is unchanged, and the angles of the transition section and the rising section are increased, so that the valve can be instantly closed, and difficult problems of long time consumption and high energy consumption when an ordinary gas valve is closed are solved.

Description

technical field [0001] The invention relates to a valve control type device, in particular to an instantaneous positioning gas valve. Background technique [0002] With the development of society, smart gas meters have begun to be widely used throughout the country, and gas companies in many places have realized intelligent management of gas. After more than ten years of development, smart gas meters have transitioned from the first generation of split smart gas meters to the second generation of integrated smart gas meters, and are developing rapidly. Due to the special structure of the integrated smart gas meter, the gas valve needs to be installed in the gas meter, so higher requirements are put forward for the matching gas valve. At present, there are two main types of gas valves used in smart gas meters: one is a solenoid valve, and the other is an electric control valve. The former has the characteristics of high manufacturing process requirements, high price, not ea...
