Description
Technical field
This utility model relates to cylinder valve technical field, refers in particular to a kind of cylinder valve limiting and illegally filling.
Background technology
Along with making rapid progress of science and technology, the management of cylinder for liquefied gas is also into the information system management stage.Install identity on cylinder for liquefied gas additional, whether whether identified that by intelligent electromagnetic charge gun realizing legal fixed point fills, and with this limit those illegally fill a little carry out illegally fill liquefied gas.
Existing restriction fills cylinder valve, and disclosed in such as Application No. CN201410540086.7, a kind of liquefied gas bottle valve, is provided with the spool that can move up and down along runner, utilizes moving up and down of spool to open and close runner in the valve flowing channel of valve.Body wall is provided with and can be provided with, by the card joint chair of the clamping mechanism clamping of electromagnetism charge gun, the sliding sleeve moved back and forth towards spool in card joint chair.During inflation, electromagnetism charge gun is connected on valve, when charge gun read the identity on body be legal information time, electromagnetic driver on charge gun starts, and drives sliding sleeve to slide to spool, orders about spool and open runner, thus can fill liquefied gas.When the identity on charge gun None-identified body or read the identity on body be invalid information time, electromagnetic driver on charge gun just cannot start, sliding sleeve keeps slipping away the state of spool under the action of the spring, and now spool closes runner so that cannot fill liquefied gas.It is magnetized for anti-anti-skid sheath, generally uses the non-magnet materials such as aluminum bronze to process.But, this restriction fills the not reasonable of the opening/shutting mode design of the spool of cylinder valve, and spool design becomes lower in-migration to open runner when filling, and this has also limited to sealing ring can only be used to the shoulder hole sealing in runner.It is true that this spool has three kinds of location status during application: when 1, using gas, spool is the most high-order by bottle internal gas pressure and spring top, and the upward out shoulder hole of sealing ring, runner is unimpeded；2, legal when filling, sliding sleeve is driven electromagnetically shifts to spool, releases the stop moving down spool, and spool, under the promotion of inner gas pressure, is displaced downwardly to low level, and sealing ring is downward away from shoulder hole, and runner is unimpeded；When 3, illegally filling, sliding sleeve does not has action under the action of the spring, keeps the stop that spool is displaced downwardly to centre position, make spool under the promotion illegally filling air pressure, sealing ring can only be displaced downwardly in the shoulder hole in centre position, is formed with shoulder hole and seals, thus closes runner.
Owing to the space of valve body is limited, therefore the removable space of spool is also limited, and the three of spool kinds of location status, also it is extremely limited for directly results in the space that spool moves up and move down, so that sealing ring opens up and opens downwards the aperture area of shoulder hole is also the narrowest.Therefore, this restriction fills the air demand of cylinder valve and aeration quantity is extremely limited, it is impossible to meet the demand of atm number.Also have this restriction to fill sliding over of cylinder valve to stop that the place rearward, end of spool must process to dodge and dodge hole when spool moves down, so add processing technique and the cost of sliding sleeve.Have again, owing to the keying of runner is to coordinate by sealing ring and sealing of shoulder hole, thus sealing ring is to need the hole wall with shoulder hole to press to form preferable sealing effectiveness, but sealing ring can add the moving resistance of large sealing packing ring to excessively pressing of shoulder hole, add the elastic force needing to overcome spring when spool moves down, sealing ring can be made to be difficult in shoulder hole move, also result in spool and cannot normally open and close runner, making it difficult to ensure that this restriction fills cylinder valve and can normally work.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, not only can meet atm number demand, moreover it is possible to ensure working stability restriction fill cylinder valve.
By solving the technical scheme that above-mentioned technical problem is used: a kind of restriction fills cylinder valve, include the valve body with runner, the spool in order to open and close runner of movement it is axially reciprocal in runner, and keep spool towards the first spring opening runner direction mobile trend, the sliding sleeve that can move back and forth facing to spool is installed and in order to sliding sleeve to be arranged on the plug screw in card joint chair in the card joint chair of body wall, plug screw is formed and extends in sliding sleeve, the ferrum core of spool can be slided to by magnetically-actuated sliding sleeve, the second spring keeping its spool trend that slips away it is set with outside sliding sleeve, it is characterized in that: in described runner, be formed with stepped hole, the tapered portion that can block stepped hole to close runner it is formed with after it moves down on spool, it is set as when sliding sleeve slides to spool between sliding sleeve and spool, sliding sleeve stops that spool moves down.
Preferable, described sliding sleeve be material be aluminum matter.
On the basis of the above, described spool is formed can by the sliding sleeve sliding to spool stop the radially protruding that move down of spool by stopper, the end of sliding sleeve is formed can keep off the stop part on the downside of by stopper.
On the basis of the above, the stop part of described sliding sleeve is formed with the fork extending in spool both sides of depression.
Use the beneficial effect that this utility model is brought: close the runner of cylinder valve owing to this utility model is set as in-migration under spool, two location status of closedown are opened and are moved down in the upper shifting of spool, and have employed tapered portion to the stepped hole closing on runner, spool be only displaced downwardly to tapered portion abut this position of stepped hole be close runner and runner all can be opened in remaining position, thus on spool, the space of runner is opened in shifting is sizable, restriction can be met completely and fill the bigger air demand of cylinder valve and the demand of aeration quantity.And during spool is displaced downwardly to tapered portion closedown runner, only need to overcome the elastic force of the first spring, it is ensured that the reliability and stability of spool work.Also having and spool design becomes lower in-migration close runner, so that sliding sleeve is without too much design, can stop that spool moves down just when only sliding sleeve need to be set as sliding to spool, such design only need to use the design of some routines to achieve that.
