Description
Technical field
The present invention relates to gas meter technical field, especially relate to a kind of control valve structure of intelligent gas meter.
Background technique
Along with developing rapidly of intelligent gas meter industry technology, the requirement of gas meter control valve also improves constantly.Early stage gas meter just judges from valve switching times and two aspects of switch valve electric current whether valve is opened simply,, in addition the sporadic fault of drive part cannot be made and being automatically terminated because the inconsistency of motor, drive part, controller power pack cannot be made correctly, judgement reliably for some.Generally adopt now band to drive put in place the valve of signal of valve, as Chinese patent notice of authorization CN2603880Y, on February 18 2004 notice of authorization day, the model utility that name is called " the intelligent gas meter induction machine valve that can detect valve plug position " is exactly one wherein.It comprises support and be arranged on valve plug, the bibcock in support, and support one side is provided with motor cabinet and motor, and valve plug top arranges a salient angle, which is provided with magnet steel; And on support, be provided with and the magneto-dependent sensor of magnet steel phase configuration.These structure existing problems: magnet steel is embedded in the groove of salient angle, there will be in actual use magnet steel change in location, even comes off.This can cause control circuit correct valve opening signal cannot be detected, thereby affects the reliability of gas meter control valve.In addition, the control valve assembly of existing intelligent gas meter adopts spool to embed the structure in rubber jam pot cover, realizes the control of spool to jam pot cover.As Chinese patent notice of authorization CN201412537Y, on February 24 2010 notice of authorization day, name is called the model utility of " valve core component of motor valve ".It comprises valve rod, spool and rubber flap, and valve rod and spool are integral with screwed connection, and spool embeds rubber flap, and rubber flap is connected with valve sealing ring.This structure is to be processed into by the front end head of spool chamfering or the fillet that several angle requires, and spool embeds rubber part flap.But because whole jam pot cover is rubber parts, jam pot cover self is easily out of shape, affects sealing effect.Secondly, in the time that the pressure that suffers misoperation access gas is excessive, jam pot cover can snap in valve port by gross distortion, and even jam pot cover and spool disengagement are fallen in gas meter, cause in the time that air pressure recovers normal, and control valve cannot recover normal work automatically.For fundamentally solve that jam pot cover comes off problem, technician proposes new solution, as Chinese patent notice of authorization CN202469033U, on October 3 2012 notice of authorization day, the model utility that name is called " motor valve for gas meter jam pot cover structure " is exactly one of them.It comprises rubber jam pot cover and lifting rack inserts, in rubber jam pot cover, have inserts, be reserved with three screw holes on inserts, jam pot cover connecting plate utilizes barb tenon to be fixedly connected with lifting rack inserts, on jam pot cover connecting plate, have three circular holes, jam pot cover connecting plate is fixedly connected with rubber valve envelope by three pieces of screws.There is following problem in this structure: although be provided with inserts in rubber jam pot cover, the sealing that jam pot cover is compressed to valve port plays reliable effect, tight in order to close valve, and the plane precision that jam pot cover contacts with valve port requires high, and processing cost is high.And what close that jam pot cover plays seal action when valve is near the side of jam pot cover end, inserts can not play a role seal operation part, and this just causes waste.This structure need be beaten after screw can rubberizing in addition, and not only production process operation inconvenience, and rubberizing process efficiency is low.
Summary of the invention
For solve the unreliable and spool self of alinco assembled on prior art gas meter spool easily distortion produce the insecure technical problem of sealing, the invention provides a kind of magnet steel the reliable gas meter control valve of firm jam pot cover sealing structure be installed.
Technological scheme of the present invention is: a kind of gas meter control valve modular construction, it comprises that side-looking is the jam pot cover frame of the word of falling T shape and the valve rod with the clamping of jam pot cover frame, jam pot cover has set up groove, in groove, be embedded with jam pot cover, above jam pot cover, be crimped with jam pot cover chuck, jam pot cover chuck and the clamping of jam pot cover frame, jam pot cover frame is also provided with the magnet steel storehouse of the cavity body structure of an end opening, and the opening end in magnet steel storehouse is communicated with groove bottom.Magnet steel is arranged in magnet steel storehouse, and magnet steel storehouse opening is covered by jam pot cover, and jam pot cover is pushed down by jam pot cover chuck, and jam pot cover chuck is stuck by jam pot cover frame again, and magnet steel is fixed in magnet steel storehouse and can not comes off, and has guaranteed the reliability of gas meter control valve position probing.Jam pot cover is blocked gas meter valve port, and jam pot cover frame edge withstands jam pot cover, and jam pot cover sealing is reliable.Jam pot cover frame and valve rod clamping, jam pot cover chuck and the clamping of jam pot cover frame, convenient for assembly enhancing productivity.
As preferably, jam pot cover frame is that a disc centre connects a cylindrical structure, and groove, along disk border setting, is provided with the chuck button that is T shape of several projections between groove and cylinder.
As preferably, jam pot cover chuck is ring, and its lower surface is provided with the clamp bar that is convex; Jam pot cover is provided with through hole in the middle of being cylindrical base, and its sidewall outer surface is provided with protuberance; Jam pot cover chuck and jam pot cover and the socket of jam pot cover frame, the bottom of jam pot cover embeds groove, and the protuberance of jam pot cover is pushed down the top of groove cell wall, the bottom crimping of clamp bar and jam pot cover.Jam pot cover non-operative end is pushed down fixing by jam pot cover chuck, bottom, working end is withstood by jam pot cover frame, and the machining accuracy of jam pot cover and valve port contact segment is easily controlled, and has both saved to have reduced jam pot cover material and reduced cost of production, the sealing reliability of poppet valve again.Jam pot cover working end is just withstood by jam pot cover frame in addition, has certain degrees of freedom, in the time that jam pot cover contacts with valve port, plays buffer function, reduces the impact of closing valve.
As preferably, jam pot cover chuck is provided with chuck buttonhole, and chuck button and chuck buttonhole match; Facilitate jam pot cover chuck to install.
