Description
Technical field
The invention belongs to a kind of built-in valve of built-in valve, particularly a kind of gas meter.
Technical background
Piped gas is widely used in commerce and civil area now, has developed different gas meters at different applications, and the domestic gas table is meant that peak rate of flow is not more than 10m
3The gas meter of/h refers generally to the gas meter that common people's family is used; Commercial combustion gas meter is meant peak rate of flow 16m
3/ h is to 160m
3The gas meter of/h, its user is hotel, hotel etc.Because commercial combustion gas meter is bigger, the valve volume that is used for commercial combustion gas meter is also bigger, is placed on gas meter inside not too easily, so the valve of common commercial combustion gas meter all is to adopt external valve on the current market, ball valve is arranged, angle valve, butterfly valve etc.This class valve is contained in the outside of gas meter, and an end is connected with the suction port of gas meter, the other end connecting tube.What this external valve was whole is exposed in the air, therefore needs to guarantee the tightness of valve, does not allow gas leakage, have potential safety hazard in case leak, and when project installation, external valve need leave the valve mounting point.
Summary of the invention
The present invention is directed to the problems referred to above a kind of valve that is installed in commercial combustion gas meter inside is provided, this valve does not directly contact with atmosphere, is opening under the valve state, combustion gas enters gas meter inside by valve port, itself has sealing gas meter, completely cuts off atmosphere, has effectively prevented the leakage hidden danger of combustion gas.
Technological scheme of the present invention is: a kind of built-in motor valve that is installed in commercial combustion gas meter inside, comprise motor, base, support and valve bung flange, motor is fixed on the base, base sheath is located in the valve bung flange, support is arranged on the base and the bottom is connected with the valve bung flange, the support roof anchorage is in the inside of gas meter, be provided with valve body in the described support, screw rod and bibcock, valve body is arranged on the base, the screw rod lower end is passed behind the valve body by gear train by driven by motor, the screw rod upper end is threaded with bibcock, bibcock is provided with the valve seal pad, described rack side wall has the groove that is used for gas communication, is provided with the valve port that matches with the valve seal pad in the support upper end-hole, and bibcock compresses by valve seal pad and valve port; The driven by motor screw rod rotates and makes the bibcock lifting realize the switch of valve.
Built-in motor valve deft design of the present invention, volume is less, by support whole valve is fixed on the inside of commercial combustion gas meter, valve does not directly contact with atmosphere, is opening under the valve state, combustion gas enters gas meter inside by valve port, itself has sealing gas meter, and isolated atmosphere has prevented the hidden danger that combustion gas is revealed, valve is built-in simultaneously, has reduced the possibility of external environment condition or artificial destruction valve; Valve rotates by the driven by motor screw rod, and the rotation by screw rod is risen bibcock or descended, and makes to compress between bibcock and the valve port or unclamp, thereby realize the opening and closing of valve port, simple in structure, easy for installation, because this valve is built-in, do not need to leave specially the position during project installation simultaneously; And when original traditional gas meter was repacked into band valve intelligence table, this valve more had superiority, and it does not need to change original pipeline wiring.
As preferably, overlap the spring that is useful on the bibcock return on the described screw rod, screw rod and bibcock screw pressure spring; When screw rod and bibcock screw-thread fit were thrown off fully, spring was used for bibcock and opens return effect behind the valve, avoids screw rod and bibcock stuck when circling round.
As preferably, described bibcock front end is provided with the valve plug nut that is used for fixing the valve seal pad, and the front end of valve plug nut adopts cone shape; Valve plug adopts cone shape to enter air flue, in order to reduce combustion gas viscosity valve plug is influenced, and reduces the pressure loss, closes the valve resistance force diminishes, closes the valve electric current and diminishes.
As preferably, be provided with in order to built-in valve is fixed on the installation foot on the gas meter on the described support.
As preferably, described valve body is provided with spring seat, and spring seat is provided with buckle; Described screw rod passes spring seat, and described spring is fixed on the buckle; Prevent the move left and right of spring like this, making it can only axial stretching.
As preferably, be covered with a motor cover on the described motor, motor cover is fixed on the base; Motor cover plays the effect of protection motor, seals up contacting of motor and outside combustion gas simultaneously.
