Problems solved by technology

[0003] These two types of valves have the characteristics of high manufacturing process and high price; the above types of valves are not easy to be fully enclosed, and are easily polluted by pipeline impurities, resulting in out-of-control valve opening and closing; the above valves have complex structures and large volumes , which is not conducive to the promotion of the use of integrated IC card membrane gas meters; the driving mechanism of the above valves also has the characteristics of large driving current and long opening and closing time of the valve. Long corresponds to the large capacity of the energy storage capacitor, so there is also a large capacitor leakage, which is likely to lead to the problem of short life of the battery used in the smart gas meter; the above valve is installed at the air inlet of the gas meter, which requires high valve sealing. The existing valve uses materials It is easy to age and become brittle, and after a long time of use, it will cause the valve to leak gas

Embodiment 1

[0033] Such as figure 1 with figure 2 As shown, a mechanism for locking the movement of a membrane gas meter includes a driving mechanism and a pin rod 7. The driving mechanism is used to drive the pin rod 7 to change position in space, and during the process of position changing of the pin rod 7 , the pin rod 7 can provide resistance to the movement of the motion transmission system of the membrane gas meter, and the above resistance is used to force the motion transmission system to stop moving.

[0034] Existing diaphragm gas meters include a metering system, a gas path system, a motion transmission system, and a counting system. Although there are many forms of the motion transmission system, its functions include when the diaphragm obtains the power to swing under air pressure. , the motion transmission system transmits the power to the valve cover for opening and closing movement, and also transmits the power to the counting system to make the gears (or character wheel...

Embodiment 2

[0039] Such as figure 1 with figure 2As shown, this embodiment is further limited on the basis of Embodiment 1: As a further technical solution for the above-mentioned mechanism for locking the movement of the membrane gas meter, in the prior art, the membrane gas meter includes a connecting rod Mechanisms, gears, etc., while the connecting rod mechanism swings in normal operation of the membrane gas meter, and the gear rotates, as an easy-to-implement scheme that provides obstacles to the movement of the membrane gas meter’s motion transmission system. The pin rod 7 It is in the shape of a rod, and the driving mechanism is connected with one end of the pin rod 7 , and the driving mechanism is used to drive the pin rod 7 to make linear reciprocating motion along the length direction of the pin rod 7 . In this solution, under the action of the driving mechanism, the pin rod 7 can reach the position where the pull rod, connecting rod, and crank in the linkage mechanism are abo...

Embodiment 3

[0051] Such as figure 1 with figure 2 As shown, this embodiment provides a membrane gas meter, which includes a gas meter body and any mechanism provided in any one of the above embodiments. The mechanism is used to provide obstacles for the movement transmission system of the membrane gas meter, forcing The motion delivery system stops moving.

[0052] The membrane gas meter provided in this case has high locking reliability and can effectively eliminate the risk of gas leakage. At the same time, it has good electrical performance, low cost, and is convenient for mass production. It does not need to make structural improvements to the existing membrane gas meter, which is convenient to implement. The pressure loss caused by the flow of natural gas is small, the locking speed is fast, and the energy consumption is small.

Abstract

The invention discloses a diaphragm gas meter and a method and mechanism for locking motion of the diaphragm gas meter. The mechanism comprises a driving mechanism and a pin rod; the driving mechanism is used for driving the pin rod to change position in space, in the position changing process of the pin rod, the pin rod can provide hindering for motion of a motion transmission system of the diaphragm gas meter, and the hindering is used for forcing the motion transmission system to stop motion. The method is a locking method for the mechanism, and the diaphragm gas meter comprises the mechanism. The gas meter, the locking method and the locking mechanism provided in the method have the advantage of being simple in scheme, the gas meter adopting the method and the locking mechanism is high in metering precision and high in pipeline locking reliability, and fluid flow resistance of the corresponding gas pipeline can be effectively reduced by adopting the locking method and mechanism.

Description

technical field [0001] The invention relates to the technical field of gas metering and on-off control, in particular to a membrane gas meter and a method and mechanism for locking the movement of the membrane gas meter. Background technique [0002] With the advancement of society and the advancement of my country's urbanization process, my country's gas meters have developed rapidly, and the penetration rate has increased significantly year by year. Due to the special structure of the integrated IC card household membrane gas meter, the gas valve must be installed in the gas meter. Therefore, higher requirements are put forward for the supporting air valve. At present, there are two main types of gas valves used in IC card membrane gas meters: one is a solenoid valve, and the other is an electric control valve. [0003] These two types of valves have the characteristics of high manufacturing process and high price; the above types of valves are not easy to be fully enclose...
