Abstract

The invention discloses a small high-precision membrane type gas meter, and relates to the technical field of membrane type gas meters. The small high-precision membrane type gas meter comprises a crank gear, a bridge type support, a rotating valve cover, side covers, diaphragms, a membrane box and a valve seat. The valve seat is assembled below the rotating valve cover by a redundance technology, and therefore, the shortcomings that a membrane type gas meter is always in small flow in a long-term using process and the precision is poor are overcome; the membrane box is assembled below the valve seat, the bridge type support is assembled on the membrane box, and by a bridge type structure, the circumstances that the rotating valve cover is broken when conveyed and faults are caused are avoided; the side covers are assembled on two sides of the membrane box and in assembly connection with the membrane box in an interference manner; a sealing piece sleeves a position where each side cover is connected with an air inlet and outlet opening of the membrane box so that press fitting sealing is realized; each diaphragm is assembled between the corresponding side cover and the membrane box to achieve a fixing and sealing effect; and the crank gear and the rotating valve cover are follow-up running mechanisms, are assembled integrally, and move synchronously. The gas meter is small, the redundance technology, the bridge type structure and the follow-up mechanisms are adopted, the integral metering precision of the membrane type gas meter is improved, the assembly process of the membrane gas meter is also reduced greatly, costs are saved, the assembly precision of the membrane type gas meter is improved, and the practicality is high.

Background technology
At present, due to diaphragm gas meter Market competition, there is transport and produce in the Household diaphragm gas meter for extensively being used The shortcomings of measuring accuracy is not high after life and death table, Long-Time Service, initial-flow is big, in order to adapt to market demand and expand the pin of company Channel is sold, is badly in need of a little cost of research and development, high-precision diaphragm gas meter.
In sum, it is imperative to design a miniaturization high accuracy diaphragm gas meter.
The content of the invention
For not enough present on prior art, the present invention seeks to be to provide a kind of miniaturization high accuracy diaphragm gas Table, using follower, improves the overall measuring accuracy of diaphragm gas meter, also greatly reduces the assembly process of diaphragm gas meter, Its assembly precision is improve, it is practical.
To achieve these goals, the present invention is by the following technical solutions realizing:The membrane type combustion of miniaturization high accuracy Gas meter, including crank gear, support, rotary valve lid, side cover, barrier film, bellows and valve seat, valve seat is assemblied in rotary valve by redundancy Lid lower section, valve seat fit beneath has bellows, and crank gear is equipped with valve seat, and crank gear adopts follower with rotary valve lid, Bridge support is assemblied on bellows, and side cover is connected with bellows using elastic conjunction, and side cover covers close with bellows air inlet/outlet junction Sealing press-fits sealing, and barrier film is assemblied between side cover and bellows fixed and seals.
Preferably, described bellows adopts two peak structure.
Preferably, described support is bridge support.
Preferably, described rotary valve lid adopts redundancy with valve seat, improve diaphragm gas meter Long-Time Service low discharge Precision is bad.
The invention has the advantages that:1st, miniaturization, high accuracy, and adopt follower:Crank gear and rotary valve Lid assembling one, synchronous play improves the stability of product operation and the relative freedom of two parts.
2nd, interference connection, plane and bimodal sealing structure:Side cover and bellows are even connected using elastic conjunction, side cover and bellows Air inlet/outlet junction set seal press-fits sealing, the design of bellows two peak structure barrier film be locked between side cover and bellows fixation and Sealing.
3rd, bridge support:Support Design adopts bridge support, prevents the broken generation failure of rotary valve lid transport, improves operation Precision, it is ensured that the gap of driving member, stable transmission during motion.
4th, redundancy:Rotary valve lid adopts redundancy with valve seat, improves the small-flow precise of diaphragm gas meter longtime running Degree is bad.
