Abstract
The invention discloses a movable joint protecting device of a gas meter, an opening that extends to a root part of a left polycyclic crank plate is arranged in the right of the device, an upper lock plate and a lower lock plate are correspondingly and respectively arranged on an outer circle curved surface at the position of the opening, a plug with a flange is arranged on the upper lock plate, the center of the plug has longitudinal intertwining seams, a jack that is matched with the plug is arranged on the lower lock plate, a jack cover that is combined with the lower lock plate into one is arranged at the lower end of the jack and surrounds the jack into a sealed pore space, and an opening end of the jack has an annular front edge that is matched with the flange on the plug in a clamping way. The invention has the following advantages: the movable joint protecting device can conveniently prevent the privately dismounting against regulation of the gas meter and the gas stealing, and simultaneously avoid the danger of gas leakage that is caused by private pipe dismounting.
Description
Technical field
The present invention relates to a kind of live joint protection apparatus of gas meter.
Background technology
At present, gas meter from pipeline demolition privately violating the regulations, is caused that metering is inaccurate, coal gas is stolen and because private folding happens occasionally pipeline gas leakage, brought inconvenience for the safe handling and the management of coal gas by artificially.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of live joint protection apparatus of gas meter is provided.
Technical scheme of the present invention is: a kind of live joint protection apparatus of gas meter is characterized in that: this device is an annular, and its inboard is provided with ring groove; On this device, opening is arranged, have on the outer shroud facade of opening inner end with this device be the flexible brace of one; The jam plate of two correspondences is up and down arranged respectively on the outer shroud facade of opening, flanged plug is arranged on upper lock plate, the jack that cooperates with the upper lock plate plug is arranged on lower locking plate, on the aperture of jack, be provided with seam.
The present invention has the following advantages: can prevent gas meter private folding violating the regulations easily, prevent that coal gas is stolen, can avoid private folding to bring the danger of pipeline gas leakage simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
