Description
Technical field
This utility model is related to one kind, is primarily adapted for use in installed in any to electrical performance demands height and to adverse circumstances
On the gas meter, flow meter having high demands.
Background technology
Gas meter, flow meter built-in motor valve is the core component inside IC-card gas meter, flow meter, is gas meter, flow meter output gas or closing output
The actuator of gas, the good whole service life with bad directly decision gas meter, flow meter of its quality.
At present, all there is any in the two way release motor valve installed and used on the gas meter, flow meter market of China, have
Excessive is consumed to the power consumption of power supply during use, have in switch valve because use environment is very severe, there is pass valve not tight
Valve opening situation not in place.
The content of the invention
This utility model aims to provide a kind of gas meter, flow meter built-in motor valve of switch valve two way release, to solve prior art
What is existed consumes excessive to the power consumption of power supply in use；And cause because use environment is very severe in switch valve
Close the problem that valve is not tight and valve opening is not in place.
The technical solution of the utility model is：A kind of built-in two way release motor valve of gas meter, flow meter, including valve seat, valve rod and close
Strip of paper used for sealing head, the top of valve rod is provided with disk, and sealing leather point is enclosed within outside valve rod and disk, and at the bottom end of the valve rod driving machine is provided with
Structure, it is characterised in that described valve rod is provided with screw, in the disk of the valve rod valve rod spring is arranged below；Described driving machine
Structure includes motor, ratchet-type rotary screw rod and ratchet-type driving wheel, and in the middle part of the central shaft of ratchet-type rotary screw rod spine is provided with
Wheel disc, on the top of the central shaft screw thread is provided with, and is connected with the screw of the valve rod bottom；It is provided with thin below the screw thread
Neck；Ratchet-type driving wheel is set with the central shaft of the ratchet-type rotary screw rod bottom, in the ratchet-type rotary screw rod and ratchet
The opposite face of formula driving wheel be provided with least two be uniformly distributed along the circumference, mutual upper ratchet lobe and lower spine of the corresponding, end face for wedge shape
Wheel lobe；Driving wheel spring is provided with below the ratchet-type driving wheel；The ratchet-type driving wheel is by gear drive and electricity
The output shaft of machine is connected.
The utility model has the advantages that：1st, small power consumption required during motor valve switch valve, power consumption during valve opening is in 30-40mA
Left and right, power consumption when closing valve in 50-60mA or so, extend accordingly while power consumption is reduced aneroid battery use time and
Life-span, this motor valve especially apply on gas meter, flow meter radio meter register or bluetooth table and note table show it is particularly evident because
More than several gas meter, flow meters in working order when, need the electricity of loss more much larger than common IC-card gas meter, flow meter, sometimes in circuit
Operation, wireless transmit, recovery signal, closing motor valve work simultaneously when, required electricity there may be wireless communication when very big
Number cannot launch, reclaim, or the situation that motor threshold switch is not in place, if using the motor valve of two way release, due to required
Electricity it is little, this several situation for appearing above can be reduced or occurred without, while also saving the cost of use of user.
2nd, the dynamics for closing valve is more than more than 3-4 times of national standard, it is ensured that gas meter, flow meter is in the case of output high pressure
No leakage.In the state of valve opening, my company devises the principle that ratchet backs towards positioning, so as to ensure that motor valve in any gas
Wait lower 100% valve opening in place.

The a plurality of radial convex being uniformly distributed along the circumference is provided with described upper ratchet lobe 53 inclined-plane relative with bottom ratchet wheel lobe 61
Rib C.
Operation principle of the present utility model：
When motor valve closes valve, after controller energization, the motor wheel 3 installed on motor 11 passes through double linked wheel 4 to motor 11
Ratchet-type driving wheel 6 is driven to rotate (see from above ratchet-type driving wheel 6 in Fig. 6 and turn clockwise), in valve rod spring 10 and drive
Under the promotion of driver spring 12, by upper ratchet lobe 61 and the ratchet cover plate 52 on ratchet-type rotary screw rod 5 of ratchet-type driving wheel 6
Frictional force between the inclined-plane fin C of bottom ratchet wheel lobe 53, drives the synchronous axial system of ratchet-type rotary screw rod 5, ratchet-type rotary screw rod 5
The screw thread 55 at top drives pull bar 8 axially upwardly to move, and the sealing leather point 7 above the top disk of pull bar 8 upwards simultaneously
Motion, after reaching a certain distance, the upper surface for sealing leather point 7 starts to contact with the seal on valve seat 9, until sealing leather point
7 reach after the sealing effectiveness of maximum with the seal on valve seat 9, act on the rotatory force on ratchet-type driving wheel 6 more than effect
The thrust of the thrust spring 12 under ratchet-type driving wheel 6, therefore, the upper ratchet lobe 61 of ratchet-type driving wheel 6 and ratchet type revolving
The bottom ratchet wheel lobe 53 of dynamic screw mandrel 5 starts mutually skidding, so as to serve the effect that valve is threaded off of closing, reduces the work(used by motor 11
Consumption.
During motor valve valve opening, after controller energization, the motor wheel 3 installed on motor 11 passes through double linked wheel 4 to motor 11
Ratchet-type driving wheel 6 is driven to reversely rotate, under the promotion of valve rod spring 10 and driving wheel spring 12, on ratchet-type driving wheel 6
The locating surface 62 that backs towards of upper ratchet lobe 61 engage with the locating surface 54 that backs towards of the bottom ratchet wheel lobe 53 on ratchet-type rotary screw rod 5,
The synchronous axial system of ratchet-type rotary screw rod 5 is driven, ratchet-type rotary screw rod 5 drives pull bar 8 to move axially downwards, installed in pull bar 8
The sealing leather point 7 on top is moved downward simultaneously, and after pull bar 8 is moved downwardly to a certain distance, the female thread on pull bar 8 falls into
At thin neck 56 on ratchet-type rotary screw rod 5, both define trip status, and pull bar 8 is not rotated further by, and also reduce the institute of motor 11
Power consumption.
