Elasticity, sealing shroud can cause leakproofness unstable because the pressure with jam pot cover frame edge causes to be easy flange tilting.
Utility model content
The purpose of this utility model is to provide for a kind of reliable sealing gas meter motor valve, the groove at jam pot cover frame edge and
Boss in mounting groove avoids the right angle cooperation between jam pot cover frame and sealing shroud so that sealing shroud makes using interference fit
With in the process will not flange tilt, it is ensured that in gas meter, flow meter motor valve seal stability.
In order to achieve the above-mentioned object of the invention, the utility model uses following technical scheme：A kind of reliable sealing gas meter, flow meter
Motor valve, including motor and valve body, the valve body include sealing shroud and jam pot cover frame, and the sealing shroud is equipped with mounting groove, described
Mounting groove is equipped with jam pot cover frame, and the inner wall of the mounting groove is equipped with boss, and the edge of the jam pot cover frame is equipped with and boss
The groove being equipped with, when the sealing shroud is set on jam pot cover frame, the boss is located in groove.
Compared with prior art, the reliable sealing gas meter motor valve of above-mentioned technical proposal is used, is had following beneficial
Effect：
One, using the reliable sealing gas meter motor valve of the utility model, rubber sleeve and the right angle interference of jam pot cover frame are avoided
Cooperation, sealing shroud will not flange tilting leakproofness is impacted.
Two, in the present invention, coordinated between groove and boss, closely mutually pressure ensures jam pot cover frame and sealing to the two
There is no the gaps of gas flowing between set, it is ensured that the leakproofness of motor valve in gas meter, flow meter.
Preferably, the boss is identical as groove size or is interference fitted.
In order to ensure that the better tightness between boss and groove, the boss are preferably circumferential along mounting groove inner wall
Annular or interruption boss, the groove are the groove being equipped with along jam pot cover frame edge and boss.
Preferably, the section of the mounting groove is U-typed.
Preferably, the boss is located at the bottom of U-typed mounting groove.
Preferably, the groove is located at jam pot cover frame side.
Preferably, the top in the section of the boss is semicircle, and the bottom in the section of the groove is semicircle.
Preferably, the boss is interference fitted with groove, and the boss is with the unilateral interference volume that groove is interference fitted
0.2mm-1mm。

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
Gas meter motor valve, including sealing shroud 1 and jam pot cover frame 2 are reliably sealed as shown in Fig. 1 to 5, Fig. 1 is that the two is installed
Structural schematic diagram afterwards, Fig. 2 and Fig. 3 are the sectional view after jam pot cover frame 2 and the installation of sealing shroud 1, and sealing shroud 1 is equipped with mounting groove
12, mounting groove 12 is equipped with jam pot cover frame, and sealing shroud 1 is set in by mounting groove 12 on the edge of jam pot cover frame 2.It is installing
When, the edge of jam pot cover frame 2 is fixed on the inside of mounting groove 12, in the present embodiment, in order to enable between jam pot cover frame 1 and sealing shroud
Can more preferably it coordinate, the inner wall of mounting groove 12 is equipped with boss 11, and the edge of jam pot cover frame 2 is equipped with groove 21, and sealing shroud 1 is set in
Boss 11 is located in groove 21 when on jam pot cover frame 2, and boss 11 is identical as 21 size of groove or is interference fitted.When boss 11 and groove
When 21 interference fit, the unilateral interference volume of interference fit is 0.2mm-1mm.
In the present embodiment, jam pot cover frame 2 is circle, and the mounting groove 12 in sealing shroud 1 is to be adapted with 2 edge of jam pot cover frame
