Description
Technical field
The present invention relates to a kind of valve, more particularly to a kind of IC card flow control low-power consumption ball valve.
Background technology
As what China's natural gas used popularizes, coal changes vigorously supporting for gas policy, and gas industry will be public utilities
Middle entirety speedup is most fast, the strongest subdivision field of growth attribute.In terms of 206,500,000,000 cubes of gas consumption in 2016, if natural by China
Gas consumes planning guidance, and the consumption figure to the year two thousand twenty China's natural gas will can then calculate 2016 up to 360,000,000,000 cubes ---
Between the year two thousand twenty, the consumption figure year of national natural gas, which increases, reaches 15%.
It is strong that gas discharge pre-payment automatically controls the product market demand, and IC card flow control valve is and gas flowmeter
Matching used control component, the two are combined into intellective IC card gas Flowrate Control System, to realize to natural gas motorcar
Flow control.Market prospects are very extensive.
Notification number is that the Chinese patent of CN202418636U discloses a kind of IC card flow control valve, the transmission mechanism
Include lead screw, main shaft, orbital member, wherein main shaft is connect with wire rod thread, and the orbital member is fixed at valve body or valve deck
On, it is provided with the through-hole of " 7 " font on orbital member, is fixedly installed axis pin on the main shaft, when main axis is existed by axis pin
Lifting and rotation or rotation and Enhance Sports are realized in limitation in " 7 " font through-hole.
Valve seat is set in above-mentioned patent in valve body, and setting can form sealing cooperation with spool in rotation on valve seat
O-ring seals are shut off by the cooperation fluid medium realization between O-ring seals and spool.Due to O-ring seals material
Friction coefficient is higher so that larger frictional resistance can be formed between O-ring seals and spool；And when O-ring seals are by height
When the active force that pressure fluid media (medium) applies it, O-ring seals can deform upon.And the increase of O-ring seals deformation quantity can be into
One step increases O-ring seals and the frictional resistance of spool between the two so that executing agency needs to apply larger driving force
Spool can be driven to be rotated, to increase the energy consumption of executing agency to a certain extent, this kind of valve be caused actually to make
Lack practicability during.
Invention content
The object of the present invention is to provide a kind of IC card flow control low-power consumption ball valve, the IC card flow control low-power consumption ball valves
Have the advantages that low-power consumption is energy saving, to promote its practicability in actual use.
The present invention above-mentioned technical purpose technical scheme is that：A kind of low work(of IC card flow control
Ball valve is consumed, including valve body, is set to the runner of valve body and is set to the valve rod of valve body, the valve body turns equipped with driving stem
Dynamic executing agency, the valve rod are equipped with the spool being located inside runner, and the runner, which is equipped with to be formed to seal with spool, matches
The valve seat of conjunction, the valve seat contradict the installation annular groove of spool offered on one side around the runner center of circle, in the installation annular groove
Gasket equipped with low friction, the interior elastic component for being equipped with driving gasket and packing tightly spool of the installation annular groove.
By using above-mentioned technical proposal, selects the gasket of low-friction coefficient for coordinating spool to form sealing, reduce
The frictional resistance that is formed between the two；And low-friction material is smaller relative to the deformation degree of O-ring seals, by high pressure
It is not susceptible to deformation when the active force that fluid media (medium) applies it.Since existing low-friction material itself does not have elasticity,
The elastic force needed for sealing cannot be generated, therefore elastic force is applied to gasket by the elastic component of setting so that gasket can wrap
Tight spool forms sealing, and makes not will produce relative motion between gasket and spool.Reduce spool in rotation process by
The frictional resistance arrived so that executing agency can drive spool to be rotated with smaller driving force, to reach reduction power consumption
With energy-efficient purpose.Make this kind of IC card flow control low-power consumption ball valve that can there is longer usage time during use,

Lubrication uses.The gasket that this kind of material is fabricated to also has good chemical stabilization on the basis of having both low-friction coefficient
Property so that it can make to be suitable for the different occasion of various applying working conditions using the valve of this kind of gasket；And O-ring seal generation
Elastic force can preferably pack tightly the gasket that material is polytetrafluoroethylene (PTFE) on spool, ensure that between gasket and spool
Sealing effect.
It is further arranged to：The valve seat includes the left valve seat and right valve seat positioned at spool both sides, the left valve seat and the right side
It is oppositely arranged between valve seat, the installation annular groove is equipped on the left valve seat and right valve seat, is equipped with and drives in the runner
Move the adjustment means that left valve seat is moved towards right valve seat direction.
By using above-mentioned technical proposal, the setting of left valve seat and right valve seat improves the sealing between valve seat and spool
Property so that under the driving of adjustment means, left valve seat can be drawn close with right valve seat simultaneously towards the direction where spool, for adjusting
Sealing force between gasket and spool.
It is further arranged to：The adjustment means include sliding along runner and the drive block of screw-thread fit and setting therewith
It is placed in adjustment spring between drive block and left valve seat.
Being threadedly coupled by using above-mentioned technical proposal, between drive block and runner enables drive block towards left valve seat direction
It is mobile, and exerted a force to left valve seat by the adjustment spring of setting, for adjust left valve seat and spool, right valve seat and spool it
Between sealing force；Again due to elastic deformation space possessed by adjustment spring, can prevent drive block in adjustment process, valve seat with
Occurs the phenomenon that locking between spool.
It is further arranged to：The first sealing ring is equipped between the right valve seat and runner.
By using above-mentioned technical proposal, the setting of the first sealing ring promotes the leakproofness between right valve seat and runner.
It is further arranged to：The drive block inner wall is equipped with direction and extends back to left valve seat direction and be gradually flared setting
Guide surface, the guide surface run through drive block back to the end face of left valve seat.
By using above-mentioned technical proposal, the setting of guide surface enables the fluid media (medium) in pipeline more smoothly to enter
Valve inner reduces fluid media (medium) vibration caused by valve body in flow process.
It is further arranged to：The inner wall of the drive block is equipped at least two and is applied around what the center of circle of drive block was distributed
Power slot, the force slot described in two is oppositely arranged and the end face through drive block back to left valve seat.
By using above-mentioned technical proposal, staff preferably can apply turning effort by the slot that exerts a force to drive block
Power, the convenient adjusting for drive block.
It is further arranged to：Multiple second sealing rings are equipped between the drive block and runner.
By using above-mentioned technical proposal, the setting of the second sealing ring promotes the leakproofness between drive block and runner.
It is further arranged to：The executing agency includes shell, motor, input shaft and transition axis, and the shell is fixed
