Have in automatically controlled intake valve in above-mentioned, the tilt angle of the fan blades is 30 degree of -60 degree.
Compared with prior art, the utility model has the advantage that
1, an automatically controlled intake valve is arranged in the utility model inside gas meter, flow meter, can high-speed switch intake valve, eliminate close
Hysteresis effect when burnt gas valve.
2, air equalizer opening being offered in fan blades, balances fan blades pressure at both sides, fan blades will not be deformed because receiving pressure,
The service life of fan blades can be increased, and stop location will not be caused to deviate because gaseous-pressure is excessive, to prevent combustion gas
Leakage.
3, bracket is equipped between motor and the inner wall of automatically controlled air inlet valve shell, bracket is by motor support outside automatically controlled intake valve
On the inner wall of shell, the good fixing effect of motor, fan blades can be rotated smoothly.
4, air inlet is provided with the upside of automatically controlled air inlet valve shell, when combustion gas enters inside gas meter, flow meter from air inlet, combustion gas
In the granule foreign that is mingled with can sink because of the weight of its own, will not enter inside gas meter, flow meter, can increase gas meter, flow meter uses the longevity
Life.
5, fan blades is obliquely installed on the rotary shaft, and when the block in fan blades blocks air inlet, fan blades is with block
One end goes to air inlet pipe side, can make combustion gas can not be close to air inlet effectively by combustion gas barrier outside air inlet；When in fan blades
When block goes to other places and do not block air inlet, fan blades goes to motor side without one end of block, stops fan blades not completely
Combustion gas enters air inlet, improves intake efficiency.
6, the tilt angle of fan blades is 30-60 degree, this angle can be such that fan blades is stably fixed in rotary shaft, and rotate
Shi Buhui generates unstable phenomenon because the component on horizontal axis is excessive.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, 2, a kind of gas meter, flow meter with automatically controlled intake valve 4, including shell of gas meter 1, outside the gas meter, flow meter
Admission line 2 and outlet pipe 3 are offered on shell 1, and automatically controlled intake valve 4 is fixed on the admission line 2；It is described it is automatically controlled into
Air valve 4 includes automatically controlled air inlet valve shell 46, and one end of the automatically controlled air inlet valve shell 46 is fixed on the inner wall of shell of gas meter 1
On, the automatically controlled air inlet valve shell 46 and 1 airtight connection of shell of gas meter offer air inlet on the automatically controlled air inlet valve shell 46
Mouth 47；The automatically controlled intake valve 4 further includes motor 41, and a rotary shaft 42 is fixed on motor 41, is fixed in rotary shaft 42
Fan blades 43, one end of fan blades 43 are provided with block 45；The location matches of the air inlet 47 and block 45, the face of the block 45
Product is greater than the area of air inlet 47.
Automatically controlled air inlet valve shell 46 and 1 airtight connection of shell of gas meter, make combustion gas can only be by automatically controlled air inlet valve shell 46
On air inlet 47 enter gas meter, flow meter in.When gas meter, flow meter air intake valve is closed, the motor 41 in automatically controlled intake valve 4 starts, rotation
Shaft 42 drives fan blades 43 to rotate, and the block 45 in fan blades 43 blocks air inlet 47, and the area of block 45 is greater than air inlet 47
Area, air inlet 47 can be sealed completely, realize quick closedown intake valve effect；When gas meter, flow meter air intake valve is opened,
Rotary shaft 42 drives fan blades 43 to rotate, and so that the block 45 in fan blades 43 is gone to other places, can smoothly enter into combustion gas can in gas meter, flow meter.This
An intake valve is arranged in utility model inside gas meter, flow meter, can quick closedown intake valve, eliminate closing gas valve door when lag
Effect.
Air equalizer opening 44 is offered in fan blades 43, balances 43 pressure at both sides of fan blades, fan blades 43 will not be because receiving pressure
And deform, the service life of fan blades 43 can be increased.
Bracket 48 is equipped between motor 41 and the inner wall of automatically controlled air inlet valve shell 46, motor 41 is supported on automatically controlled by bracket 48
On the inner wall of air inlet valve shell 46, the good fixing effect of motor 41, fan blades 43 can be rotated smoothly.
Air inlet 47 is provided with the upside of automatically controlled air inlet valve shell 46, when combustion gas is entered inside gas meter, flow meter from air inlet 47,
The granule foreign being mingled in combustion gas can sink because of the weight of its own, will not enter inside gas meter, flow meter, can increase making for gas meter, flow meter
Use the service life.
Fan blades 43 is inclined in rotary shaft 42, when the block 45 in fan blades 43 blocks air inlet 47, fan blades 43
One end with block 45 goes to air inlet pipe side, can effectively by combustion gas barrier outside air inlet 47, make combustion gas can not close into
Port 47；When the block 45 in fan blades 43, which goes to other places, does not block air inlet 47, fan blades 43 turns without one end of block 45
To 41 side of motor, make fan blades 43 that combustion gas not stopped to enter air inlet 47 completely, improves intake efficiency.
The tilt angle of fan blades 43 is 30-60 degree, this angle can be such that fan blades 43 is stably fixed in rotary shaft 42, and
Rotation makes that unstable phenomenon will not be generated because the component on horizontal axis is excessive.
