Description
The utility model relates to a kind of gas meter, flow meter, especially thief-proof automatic protection gas meter, flow meter.
Along with improving constantly of people's lives, gas meter, flow meter has been come into huge numbers of families.The metering of right gas management department by gas meter, flow meter manages and collects the charges.Because one or two people exempt from or underpay expense in order to steal gas, and are artificially that gas meter, flow meter is crooked, make valve block inclined disengaging the under the deadweight effect that lies on the valve seat produce a gap with valve seat, combustion gas flows to burner along the gap, causes metering inaccurate.Also some people oppositely is connected the turnover pipe of gas meter, flow meter with burner, makes the crank and rocker mechanism counter-rotating or the stall of the metering that can only turn clockwise, and reaches and steals the purpose that gas is not paid dues.Because the artificial meter that leaks, not only civil gas management division management inconvenience, and cause bigger economic loss to country.
The purpose of this utility model provides a kind of thief-proof automatic protection gas meter, flow meter, by the artificial leakage meter that anti-theft device of gas and anticreep steady arm prevent gas meter, flow meter being set, the normal metering of monitoring gas meter, flow meter.
Concrete scheme of the present utility model is: draft tube, bend pipe, articulation, crank and rocker mechanism, rocking bar, spacing ring, air chamber, valve seat, shell, valve block, escape pipe, escape pipe joint is characterized in that: the anticreep steady arm is installed on valve block; In escape pipe or between escape pipe and the escape pipe joint, anti-theft device of gas is housed.
The employing such scheme need not change former gas meter, flow meter structure, and is easy for installation, both can prevent the artificial leakage meter of gas meter, flow meter, monitors the normal metering of gas meter, flow meter, can prolong the serviceable life of gas meter again.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a front view of the present utility model, also is first kind of embodiment of the present utility model, and it is the situation that anti-theft device of gas 12 is positioned at escape pipe 13;
Fig. 2 is the B-B cut-open view of Fig. 1;
Fig. 3 is the annexation figure between anticreep steady arm 10 and valve seat 8 among Fig. 2, the valve block 11;
Fig. 4 is second kind of embodiment of the present utility model, also is the another kind of B-B cut-open view of Fig. 1, and it is the situation of anti-theft device of gas 12 between escape pipe 13 and escape pipe joint 14;
Fig. 5 is anti-theft device of gas 12 rollover states figure.
From above-mentioned accompanying drawing as can be known: the utility model mainly is made up of draft tube 1, bend pipe 2, articulation 3, crank and rocker mechanism 4, rocking bar 5, spacing ring 6, air chamber 7, valve seat 8, shell 9, anticreep steady arm 10, valve block 11, anti-theft device of gas 12, escape pipe 13, escape pipe joint 14, pinch roller 15, gag lever post 16, elastic pressuring plate 17, wheel pressing shaft 18, adjusting screw 19, unidirectional valve seat 20, spring 21, check valve sheet 22, choke cover 23, counterweight 24, chock flap 25, and architectural feature of the present utility model is: anticreep steady arm 10 is installed on valve block 11; In escape pipe 13 or between escape pipe 13 and the escape pipe joint 14, anti-theft device of gas 12 is housed.
As shown in Figure 3: anticreep steady arm 10 is made up of pinch roller 15, elastic pressuring plate 17, wheel pressing shaft 18, adjusting screw 19, and wherein 17 1 of elastic pressuring plates are connected with pinch roller 15, and the other end is fixed on the valve seat 8 through adjusting screw 19, and pinch roller 15 falls in the groove of valve block 11.When gas meter, flow meter was crooked, pinch roller 15 was pressed on the valve block 11 all the time, thereby prevented that combustion gas runs off from the gap that valve block 11 and valve seat 8 produces.
As shown in Figure 1 and Figure 2: the anti-theft device of gas 12 that is installed in the escape pipe 13 is made up of unidirectional valve seat 20, spring 21, check valve sheet 22, choke cover 23, counterweight 24, chock flap 25, wherein the retaining valve that is made of unidirectional valve seat 20, spring 21, check valve sheet 22 is positioned at the top of choke cover 23, is hinged with counterweight 24 and chock flap 25 below choke cover 23.
As shown in Figure 4: the anti-theft device of gas 12 that is installed between escape pipe 13 and the escape pipe joint 14 is made up of unidirectional valve seat 20, spring 21, check valve sheet 22, choke cover 23, counterweight 24, chock flap 25, outer tube 26, wherein unidirectional valve seat 20, spring 21, check valve sheet 22, choke cover 23, counterweight 24, chock flap 25 are contained in the outer tube 25, the retaining valve that is made of unidirectional valve seat 20, spring 21, check valve sheet 22 is positioned at the top of choke cover 23, is hinged with counterweight 24 and chock flap 25 below choke cover 23.
Can further find out from Fig. 1, Fig. 2, Fig. 4: two chokes cover 23 is arranged the anti-theft device of gas 12, and each choke overlaps 23 belows, and to be hinged with 24 of 24, two pairs of counterweights of a pair of counterweight vertical mutually, and each counterweight 24 is furnished with a chock flap 25.Have venthole on the unidirectional valve seat 20, central authorities' (promptly the choke between two counterweights 24 puts) of choke cover 23 have air admission hole; Check valve sheet 22 is positioned at the air admission hole top.
As can be seen from Figure 5: if surreptitiously the gas person is crooked with gas meter, flow meter, counterweight 24 and chock flap 25 can be closed the air admission hole that choke overlaps 23 central authorities automatically under the deadweight effect.
The utility model can prevent that not only artificial crooked gas meter, flow meter from stealing the behavior of gas by the counterweight 24 in anticreep steady arm 10 and the anti-theft device of gas 12, and can prevent that solid meaning oppositely is connected the artificial leakage meter that the turnover tube passage of gas meter, flow meter is carried out by spring in the anti-theft arrangement 12 21 and check valve sheet 22.
