Abstract
A triplex leakage-proof device of motor valve for high-capacity gas meter comprises a valve body of motor valve, a valve rod of motor valve and an electric appliance control part, the valve rod of the motor valve is placed in the valve body of the motor valve, the electric appliance control part is fixed on the valve body of the motor valve, the upper part of the valve rod of the motor valve is sealed by a double-passage O-shaped rubber sealing ring, the upper and lower moving positions of the valve rod of the motor valve are sleeved with corrugated rubber sealing sleeves, a clock cover-shaped sealing cover and a rubber sealing ring are added to the electric appliance control part. The utility model completely solves the leakage problem of the IC card industrial film type gas meter or other gas flow rate meters in use, the safe and normal use of the gas is guaranteed, the useful time of the motor valve is prolonged, and the maintenance pressure is reduced.
Description
Technical field
The utility model relates to a kind of motor valve, refer in particular to a kind of high-capacity gas table triple leakage preventer of motor valve, be mainly used on the electric valve machine of the industrial diaphragm gas meter of IC-card or other gas meters, as the effective means of gas safety cut-off anti-leak.
Background technique
Be used for the motor valve on the industrial diaphragm gas meter of IC-card or other gas meters at present, though it is its internal structure has the measure of anti-leak, all more single, in use, will lose efficacy, cause gas leakage in case damage to some extent, dangerous, influence combustion gas and normally use.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of high-capacity gas table with the multiple leakage preventer of motor valve, and it guarantees motor valve reliability and working life in use.
For achieving the above object, the solution that the utility model is taked is: a kind of high-capacity gas table triple leakage preventer of motor valve, it comprises motor valve body, motor valve valve rod and electrical control part, motor valve valve rod places in the motor valve body, electrical control part is fixed on the motor valve body, motor valve valve rod top is sealed by two pass O type rubber seal, the corrugated rubber sealing boot is overlapped in the position that moves up and down of motor valve valve rod, installs bell jar type seal closure and rubber seal additional at electrical control part.
The utility model can both prevent gas leakage effectively, reliably when the motor valve when opening or closing.The firstth, utilization two pass O type rubber seal is to motor valve valve stem seal; The secondth, use special corrugated rubber sealing boot, prevent that combustion gas from flowing into motor valve rod place, leak along the moving up and down of motor valve valve rod (unlatching of valve or close) time; The 3rd is to install bell jar type seal closure and rubber seal additional in electrical equipment control portion, prevents combustion gas in case leak from motor valve valve rod, also can not make gas leakage to motor valve body outside.Its feature is: (1) multiple tracks containment measures can definitely guarantee gas safe, normal long-term the use.(2) the single leakage preventer of the containment measures of all Gas appliances is faulty, must two-fold or the above leakage preventer of two-fold have simultaneously and be only reliably.The utility model has thoroughly solved the leakage problem in industrial diaphragm gas meter of IC-card or the use of other gas meters, has guaranteed safe, the normal use of combustion gas, has prolonged the working life of motor valve simultaneously, has alleviated maintenance pressure.
Description of drawings
Fig. 1 is the structural representation of present embodiment (state during valve opening).
Among the figure: 1, bell jar type seal closure, 2, rubber seal, 3, two pass O type rubber seal, 4, the corrugated rubber sealing boot, 5, the motor valve body, 6, motor valve valve rod, 7, electrical control part.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of high-capacity gas table triple leakage preventer of motor valve, it comprises motor valve body 5, motor valve valve rod 6 and electrical control part 7, motor valve valve rod 6 places in the motor valve body 5, electrical control part 7 is fixed on the motor valve body 5, motor valve valve rod 6 tops are by 3 sealings of two pass O type rubber seal, and corrugated rubber sealing boot 4 is overlapped in the position that moves up and down of motor valve valve rod 6, installs bell jar type seal closure 1 and rubber seal 2 additional at electrical control part 7.
