The check valve of reverse flow.
What the purpose of this utility model was realized in：
A kind of check valve for gas meter, flow meter, including hollow one-way valve seat, the upper surface of the one-way valve seat can fit
The diaphragm that shape is adapted is provided with, the diaphragm one end is installed on one-way valve seat；The upper surface of the one-way valve seat is also
If being provided with arterial highway reinforcement, the upper surface of the reinforcement and the upper surface of one-way valve seat are disposed on the same plane.
Preferably, the top edge of the one-way valve seat is provided with the mounting post that at least one installs diaphragm, mounting post and blocked
Installation sheet is connected to, the diaphragm is installed on one-way valve seat by installation sheet.
Preferably, the installation sheet is sheet metal.
Preferably, the reinforcement includes the cross reinforcing and waling being uniformly arranged, the cross reinforcing
With waling formation network structure.
Preferably, the diaphragm is leather diaphragm.
Preferably, the lower edge of the one-way valve seat is provided with flanging.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
The utility model controls the flow direction of combustion gas by epithelium, when combustion gas is flowed out from outlet pipe, because epithelium
Light weight, resistance is small, is easily opened under combustion gas drive, therefore crushing very little.When combustion gas from outlet pipe enters fashionable, in combustion
Under gas effect, epithelium is close to the upper surface of one-way valve seat, and blast tube is closed, and combustion gas will be unable to enter.
Diaphragm of the present utility model is installed on one-way valve seat by installation sheet, and its is simple in construction, reliable and stable, assembling effect
Rate is high.
The utility model is mounted on the outlet pipe of gas meter, flow meter, can prevent natural gas reverse flow, influences gas meter, flow meter
Element precision and normal use time, the potential safety hazard such as gas leakage is reduced, while reducing the loss for being clear gas supplier.
