Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification:
Gas outlet screw-down valve built in a kind of gas meter, flow meter, screw-down valve are mounted at gas meter, flow meter gas outlet, and screw-down valve includes air inlet
Adapter tube 1, outgoing gas connection tube 2 and transmission mechanism 3, setting sealing ring 5(has played valve close between air inlet tube and outgoing gas connection tube
Envelope effect) and connected by tapping screw 14, air inlet tube and outgoing gas connection tube sealing constitute screw rod valve insertion 15, and transmission mechanism is set
It sets in screw rod valve insertion 15, increases the flowing space of combustion gas, and the impact of combustion gas is obstructed also very in flow process
It is small, must reduce the crushing of valve significantly, and then gas meter, flow meter crushing also can very little, transmission mechanism passes through the valve of jam pot cover and air inlet tube
Mouth sealing cooperation.
More round bumping posts 16 are set on air inlet tube, and transmission mechanism is equipped with by round bumping post in air inlet tube
On；Round bumping post can limit the angle of the mobile hour offset of jam pot cover so that jam pot cover 7 be unlikely to deviate during switch valve it is excessive
And gas leakage when causing to close valve；Round bumping post end is additionally provided with screw hole location 17, can be by round bumping post and motor valve by screw
Air inlet tube, i.e., connect by cover board 4 and partition 8 with transmission mechanism；It is additionally provided with positioning groove 18 on round bumping post simultaneously, for fixed
Position motor valve cover 4, facilitates installation.Air inlet tube 1 further includes valve port 19, that is, when closing valve, jam pot cover withstands valve port 19 and closes valve.Air inlet
Locating fastener 20 is additionally provided on adapter tube 1, when installing valve in gas meter, flow meter, which plays positioning action, side
Just it installs.
The transmission mechanism of the utility model is by motor 12, gear set 13, screw rod 11, nut 10, partition 8, motor valve cover
4, epithelium 6, jam pot cover pressing plate 9 and jam pot cover 7 are constituted, and motor and gear set are fixed on partition 9 with merga pass motor cover 24,
Partition 8 and the cooperation clamping of motor valve cover 46 one end of epithelium, prevent epithelium 6 in 7 motion process of jam pot cover to be detached from partition 8, epithelium is another
One end is clamped by nut 10, jam pot cover pressing plate 9 and jam pot cover 7, and the screw rod of setting connection gear group, nut are arranged in jam pot cover pressure in partition
Between plate and jam pot cover, nut interlocking is arranged in the inner cavity of jam pot cover, and motor-driven gear group rotation, gear set drive screw rod turns
Dynamic, screw rod and nut threaded, screw rod rotation drive nut to move up and down, and nut drives jam pot cover to move up and down and completes switch valve
Movement.
Threading hole 22 is set on outgoing gas connection tube 2, rubber plug 21 is set in threading hole 22, is arranged on rubber plug 21 and wears
String holes position, two core conducting wires are drawn from transmission mechanism, are then pierced by from two threading hole locations of rubber plug 21, then in sealant
The sealing of 23 applying paste of slot.
Valve event process is as follows: driving first by motor 12, gear set 13 is driven to be driven, then screw rod 11 is driven to revolve
Turn, then screw rod 11 and nut 10 are threadedly engaged connection, drive nut 10 to move up and down, and then jam pot cover 7 is driven to make switch valve fortune
It is dynamic.When closing valve in place, screw rod still covers in nut, efficiently avoids screw rod and nut and is detached from and leads to threshold switch not just
Normal risk, simultaneously because jam pot cover uses nitrile rubber, when closing valve, jam pot cover and valve port are interference fitted, so that valve pass valve is tight,
There is no gas leak phenomenons；Valve opening in place when, screw rod withstands jam pot cover, due to jam pot cover material be nitrile rubber, it is flexible, effectively
Abrasion caused by ground avoids screw rod due to its movement.
