Retrieval is found, the applying date is 1991.01.15, application number is that 91200552.1 Chinese patent application discloses a kind of piecing devices, this device is by fittings body, collar nut, the clips courage is formed, and the fittings body cylindrical has one section outside thread, and interior is that spill is bored the chamber, collar nut is screwed on the outside thread of fittings body, in spill awl chamber is arranged, the clips courage be two ends for being conical tapered sleeve, make by elastic material, the one end stretches in the spill awl chamber of fittings body, the other end stretches in the spill awl chamber of collar nut, by tightening collar nut, crush seal folder courage, can hold the pipe that is connected tightly, to reach the purpose that is tightly connected.
The nut of above prior art structure all need be made tapering, and technology is comparatively complicated, and facts have proved that anti-pulling performance in use is not ideal enough, when therefore being used to hold on the source bottle of the poisonous hazardous chemicals of phosphorus oxychloride and so on, still has improved necessity.
Summary of the invention
The objective of the invention is to: at the shortcoming that above prior art exists, propose a kind of technology convenience, sealing reliably, and have the valve piece of dedicated composite tubing for source bottle of good resistance drawing property.
In order to reach above purpose, valve piece of dedicated composite tubing for source bottle of the present invention comprise close-fitting be inserted into locking cap, lower end mouth external thread rotary under the valve body on the bottle tracheae of source be combined in two current flow angle valve bodies in the locking cap internal thread under the valve body, from top to bottom the spool of spinning in described valve body, be screwed in the valve port locking cap of valve body side ports locking flexible pipe, its improvements are, the side ports of described valve body and lower end mouth are shaped on the little indent taper hole of outer imperial palace, the tapered sleeve that plug-in mounting matches with it in the described taper hole, the exterior edge face of described tapered sleeve is concordant with the interior threaded hole bottom plane of corresponding locking cap.
Like this, the internal thread locking cap needn't be made inner cone, so technology is simple.When its outside thread corresponding with valve body port screws, the banding effect of producing that is squeezed of tapered sleeve wherein to endoporus tracheae or flexible pipe, thus realize being tightly connected reliably.When it is subjected to the drawing active force, on the surface, the pulling capacity direction is consistent with the direction that tapering is got loose, this valve body port is shaped on the little taper hole of outer imperial palace and is unfavorable for improving anti-pulling, therefore original technology adopts valve body port to make the structure of outer little interior big conehead for a long time, and think that this structure can be subjected to force direction consistent with tapering wedging direction, so the anti-pulling performance be good when receiving drawing.Actually this is not so.The claimant is through scrutinizing discovery, and for the link of plastic flexible pipe and so on and salt, the key that influence the anti-pulling performance is its little distortion situation when locking.Little being deformed into along the wedge structure that original technology produces flexible pipe, the flexible pipe convergent can break away from during drawing.And little being deformed into against the wedge structure that the present invention produces flexible pipe can form " only pulling out step ", and flexible pipe must could break away from sudden contraction during drawing, therefore has the anti-pulling performance than the obvious enhancing of prior art.
One of well designed of the present invention is that the tapering of the port indent taper hole of described valve body is greater than the tapering of described tapered sleeve.Like this, can make during locking the inner of tapered sleeve on flexible pipe, form the darker step that only pulls out.
Two of well designed of the present invention is the port indent taper hole of described valve body and endoporus joint arc transition.Like this, also can make during locking the inner of tapered sleeve on flexible pipe, form the darker step that only pulls out.
In order to make the more reliable anti-pulling performance of having of pipe valve and source bottle, the present invention further improves, be inserted into tapered sleeve in the described valve body lower end mouth and following locking cap and the opening retainer be housed between axially, described opening retainer and source bottle tracheae necking down groove match, and fit by the interior threaded hole bottom plane of locking cap under opening retainer and the valve body in described tapered sleeve exterior edge face.Like this, except the tapering wedging, the opening retainer also plays the effect of axle position back-up ring, reliably avoids slippage.
This shows, the present invention is by scrutinizing, broken through the traditional concept that surface phenomenon produces, adopted off the beaten track tapered configuration, can guarantee that pipe valve is locked on the tracheae of source bottle or avoids flexible pipe slippage from the valve body, effectively avoids the leakage of the poisonous hazardous chemicals of phosphorus oxychloride and so on.
