The utility model content
Gap width between guide pole and the slide-valve caping end is reached approach zero, thus guarantee gas meter sleep put or inversion state under the diaphragm gas meter slip valve gap that still can normally count crack micromatic setting continuously.
For solving the problems of the technologies described above, diaphragm gas meter slip valve gap of the present utility model is the crack micromatic setting continuously, comprise slip valve gap, valve grid and guide pole, be sliding contact between slip valve gap and the valve grid, guide pole is a U font double thread structure, guide pole middle part is arranged in the gathering sill of slip valve gap, and guide pole two has threaded portion to snap in the vertical groove of valve grid both sides and is with fine-tuning nut thereon, and this fine-tuning nut is spacing in the horizontal groove that intersects with described vertical groove.
Because guide pole has adopted U font double thread structure, fine-tuning nut is spacing can only to rotate in horizontal groove, utilize the threaded screw rod principle, turn fine-tuning nut again when the assembling of each parts puts in place substantially, guide pole just moves down, by doing trickle adjustment by hand, just can make the gap width between guide pole and the slip valve gap reach minimum, and level off to zero, in vertical groove that guide pole, fine-tuning nut are housed respectively and horizontal groove, add bonded adhesives then, after treating that glue dries, the relative position between guide pole and the slide-valve caping end is just fixing.Guide pole two need not be bent into the dogging structure, processes simpler.
The beneficial effects of the utility model are: level off to zero by at assembling stage the gap between guide pole and the slide-valve caping end being fine-tuning to, it is arbitrarily angled that gas meter is tilted to, even sleep put or inversion state lower slider valve gap and valve grid workplace between can the gap not occur yet and leak gas, thereby guaranteed the accuracy and the reliability of gas meter metering, prevented that the combustion gas user from using combustion gas steathily by the laying state that changes gas meter.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
