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.
