Description
Technical field
The present invention relates to cylinder valve technical field, a kind of cylinder valve for limiting and illegally filling is referred in particular to.
Background technology
With making rapid progress for science and technology, the management of cylinder for liquefied gas also enters the information system management stage.Cylinder for liquefied gas
On install identity additional, realize that legal fixed point is filled by the way that whether whether intelligent electromagnetic charge gun recognize, and limited with this
Those illegally fill the illegal of a progress and fill liquefied gas.
Existing limitation fills cylinder valve, such as a kind of valve of liquified gas bomb disclosed in Application No. CN201410540086.7
In door, the valve flowing channel of valve provided with the valve element that can be moved up and down along runner, runner is opened and closed using moving up and down for valve element.
Body wall provided with can by the clamping mechanism clamping of electromagnetism charge gun clamping seat, clamping seat in be provided with it is reciprocal towards valve element
Mobile sliding sleeve.During inflation, electromagnetism charge gun is connected on valve, when the identity that charge gun is read on body is legal
During information, the electromagnetic driver on charge gun starts, and driving sliding sleeve slides to valve element, drives valve element to open runner, so as to fill
Liquefied gas.When the identity on charge gun None- identified body or the identity read on body are invalid information,
Electromagnetic driver on charge gun can not just start, and sliding sleeve keeps slipping away under the action of the spring the state of valve element, now valve element
Close runner so that liquefied gas can not be filled.It is magnetized for anti-anti-skid sheath, generally using the processing of the non-magnet materials such as aluminum bronze
Into.But, it is not reasonable that this opening/shutting mode for limiting the valve element for filling cylinder valve is designed, and spool design is opened into lower in-migration fills
Runner during dress, this has also limited to the shoulder hole that can only be sealed using sealing ring in runner.In fact, this valve element is in application
During be that there are three kinds of location status：When the 1st, using gas, valve element is by air pressure in bottle and spring top to a high position, and sealing ring is upward
Shoulder hole is left, runner is unimpeded；2nd, legal sliding sleeve, which is driven electromagnetically, shifts to valve element when filling, and releases the stop moved down to valve element,
Valve element is displaced downwardly to low level under the promotion of inner gas pressure, and sealing ring is downward away from shoulder hole, and runner is unimpeded；When the 3rd, illegally filling,
Sliding sleeve is not acted under the action of the spring, is kept being displaced downwardly to valve element the stop in centre position, valve element is illegally being filled gas
Under the promotion of pressure, sealing ring can only be displaced downwardly in the shoulder hole in centre position, sealed with shoulder hole formation, so as to close runner.
Because the space of valve body is limited, therefore the removable space of valve element is also limited, and three kinds of positions of valve element
Configuration state, also directly results in the space that valve element moves up and move down be it is extremely limited so that sealing ring to
The aperture area of upper opening and downward opening shoulder hole is also extremely narrow.Therefore, it is this to limit the air demand for filling cylinder valve
It is extremely limited with aeration quantity, it is impossible to meet the demand of atm number.Also it is this limit fill cylinder valve slide over stop valve
Place must process the avoidance hole for avoiding valve element when moving down rearward for the end of core, so add sliding sleeve processing technology and into
This.Further, because the keying of runner is the sealing cooperation by sealing ring and shoulder hole, thus sealing ring is needs and shoulder hole
Hole wall press and could form preferable sealing effectiveness, but sealing ring can increase the shifting of sealing ring to excessively pressing for shoulder hole
Dynamic resistance, needs to overcome the elastic force of spring when moving down along with valve element, sealing ring can be caused to be difficult to move in shoulder hole, also
Cause valve element can not normally open and close runner, making it difficult to ensure it is this limitation fill cylinder valve can normal work.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind is simple in construction, atm number demand can be not only met, moreover it is possible to protect
The limitation of card working stability fills cylinder valve.
To solve the technical scheme that above-mentioned technical problem is used：One kind limitation fills cylinder valve, includes with runner
Valve body, in being axially reciprocal the mobile valve element to open and close runner in runner and keep valve element towards opening runner direction

Sliding sleeve is arranged on the plug screw in clamping seat, and plug screw, which is formed with, to be extended into sliding sleeve, can slide to valve element by magnetically-actuated sliding sleeve
The second spring for keeping its valve element trend that slips away is set with outside iron core, sliding sleeve, it is characterised in that：Step is formed with the runner
Be formed with hole, valve element after it is moved down can block stepped hole be set as to close the tapered portion of runner, between sliding sleeve and valve element work as
When sliding sleeve slides to valve element, sliding sleeve stop valve element move down.
Preferable, the sliding sleeve is that material is aluminum.
On the basis of the above, the radially protruding that the sliding sleeve stop valve element of valve element is moved down can be slided to by being formed with the valve element
By stopper, the end of sliding sleeve forms the stop part that can be kept off on the downside of by stopper.
On the basis of the above, the stop part of the sliding sleeve is formed with the fork for extending in valve element both sides of depression.
The beneficial effect brought using the present invention：Because the present invention is set as the runner that in-migration under valve element closes cylinder valve, valve
Core only moves up opening and moves down two location status of closing, and employs tapered portion to close the stepped hole on runner, valve
It is to close runner and remaining position can all open runner that core, which is only displaced downwardly to tapered portion and abuts stepped hole this position,
The space that thus valve element moves up opening runner is sizable, and limitation can be met completely and fills the larger air demand of cylinder valve and aeration quantity
Demand.And during valve element is displaced downwardly to tapered portion closing runner, only need to overcome the elastic force of the first spring, it is ensured that valve
The reliability and stability of core work.Spool design is also closed into runner into lower in-migration, can cause what sliding sleeve need not be excessive
Design, can stop that valve element is moved down just when only sliding sleeve need to be set as sliding to valve element, what such design only need to be conventional using some
Design is achieved that.
