Description
Technical field
The present invention relates to a kind ofly decide the core joint valve and use this to decide the self-sealing joint assembly of core joint valve.
Background technique
in some main equipments of aviation or navigational field, its hydraulic servomechanism overall volume is large, Heavy Weight and mostly need to connect long pipeline, this kind servomechanism must carry out strict testing property before installation, restriction due to the installation place, often need that it is carried to other place and test detection, and usually adopt nut to be fixedly connected with between the pipeline of most servomechanism, this gives the transportation of servomechanism and field trial installation has been caused greatly inconvenience, not only carrying, dislocation that dismounting bothers and pipeline easily twists, thereby reduce the reliability of product.
in order to address the above problem, various self-sealing joints have appearred on market, application number is the disclosed water of the Chinese patent of 02260880.X is exactly wherein a kind of with two-way fast insert-pull joint, described water comprises be used to being connected to each other with two-way fast insert-pull joint decides core joint valve and moving core joint valve with the corresponding pipeline of conducting, describedly decide the core joint valve and comprise the first valve body, the bayonet end of the front end of described the first valve body for being used for pegging graft with described moving core joint valve, the rear end is provided with the first valve seat, be the pipeline connecting end that is used for connecting with corresponding pipeline, in the first valve body, concentricity line has first passage, fixedly be equipped with fixed valve plug in described first passage, the front end of described fixed valve plug (near an end of the front end of described the first valve body) has a pre-large post-small conehead and be arranged with a sliding sleeve between its rear end and conehead, the front end of described sliding sleeve has the taper hole section adaptive with the conical surface of described conehead, be top-loaded with the first spring between rear end and described the first valve seat, the outer circumferential face of sliding sleeve coordinates with the internal face slipper seal of described the first valve body, described moving core joint valve comprises the second valve body, the front end of the second valve body is for being used for and the described bayonet end of deciding the grafting of core joint valve, the pipeline connecting end of the other end for being used for connecting with corresponding pipeline, has second channel in the second valve body and the concentricity traditional thread binding movable valve plug of being furnished with in described second channel, the front end of the second valve body have turn down in described second channel in turn edge, the rear end has the second valve seat, has the joint that is connected for pipeline on the second valve seat, be top-loaded with the second spring between the rear end of described movable valve plug and described the second valve seat, turn edge in the other end and the second valve body front end and be sealed and matched.In addition, on described first, second valve body, correspondence is respectively arranged with adpting flange, and adpting flange is used for both fixing by bolt after described first, second valve body is pegged graft.
above-mentioned water with two-way fast insert-pull joint when needs dock, with described fixed, first of moving core joint valve, the second valve body is pegged graft, first, in the process that the second valve body plugs together mutually, the front end of described the second valve body pushes up gradually presses described sliding sleeve, the elastic force that makes sliding sleeve overcome described the first spring breaks away from described fixed valve plug gradually, thereby realize deciding the unlatching of core joint valve, meanwhile, described movable valve plug is pressed on described fixed valve plug top, movable valve plug is depressed the elastic force that overcomes the second spring on the top of fixed valve plug, thereby break away from described the second valve body front end in turn edge, open moving core joint valve, it is fixed to realize, conducting between moving core joint valve, namely realize the conducting between corresponding two pipelines, at this moment, by first, the adpting flange of the correspondence on the second valve body is fixed two joint valves and is got final product, in the time of two pipelines need to being disconnected, at first unclamp described adpting flange, then unplug first, second valve body, in the process that first, second valve body separates, the front end of the second valve body breaks away from described sliding sleeve, slide over and reset under the elastic force of the first spring and be sealed and matched with the conehead of fixed valve plug, thereby will decide the sealing of core joint valve, meanwhile, movable valve plug breaks away from fixed valve plug and resets under the effect of the second spring, thereby with described moving core joint valve sealing, realize the selfsealings after fixed and moving core joint valve separates.
above-mentioned self-sealing joint assembly is widely used in actual production, but still there is following problem in it: 1) fixed, under the separated state of moving core joint valve, in the sliding sleeve of deciding the core joint valve, outer wall respectively with the conehead of fixed valve plug, the internal face of the first valve body is sealed and matched, namely slide under the selfsealings state of deciding the core joint valve and be sealed and matched a little by two places, this requires fixed valve plug, cooperation between the first valve body and sliding sleeve is necessary and tight, increase widely the requirement to the machining accuracy of each parts, and be end face-end face seal between the outer wall due to the internal face of sliding sleeve and conehead, therefore very easily be subject to the impact of the impurity in medium or medium, make its seal failure, 2) because fixed and moving core joint valve is to fix by flange when connecting, therefore very inconvenience of dismounting, this has reduced work personnel's working efficiency on the one hand, increased on the other hand staff's labor intensity, most importantly increased the volume of fixed and moving core joint valve, its occasion at some limited spaces can not be used.
Summary of the invention
The object of the present invention is to provide a kind of core joint valve of deciding, with the problem of the poor sealing performance that solves existing self-sealing joint; Simultaneously, the present invention also aims to provide a kind of above-mentioned self-sealing joint assembly of deciding the core joint valve that uses.
in order to address the above problem, of the present inventionly decide the core joint valve by the following technical solutions: a kind ofly decide the core joint valve, comprise valve body and be assemblied in the valve seat of described valve rear end, be provided with the spool that is fixed on described valve seat in described valve body, be provided with sliding sleeve along the movable Anti-slip cover of fore-and-aft direction on described spool, be top-loaded with Returnning spring between the rear end of described sliding sleeve and valve body or valve seat, has a seal spool section on described spool, has medium channel in spool, described medium channel have be positioned at described spool rear end be used for receive corresponding pipeline medium the medium import and be positioned at the media outlet that described seal spool section week makes progress, have on described sliding sleeve for coordinating to seal the sliding sleeve seal section of described media outlet with the slipper seal of described seal spool section, sliding sleeve has the opening travel that slides backward to open described media outlet with respect to spool.
