Abstract
This invention is one kind is suitable to each kind of pipeline release lever is the fast pipeline connection method. Is realizes the pipeline through a crank release lever leverage fast to shrink tight and the seal connection structure, including the crank release lever, the tension bar, the spindle, pulls mandrel, the fitting main body, locks the band, the locator card, the clamp, the gasket, the packing ring. States the crank release lever, the tension bar, the spindle is leaves the plant when the product already the necessary assembly on the fitting main body, installs when first will lock the band, the clamp, the gasket, the packing ring in order set in the pipe nose, then in this nose insertion essential main body cavity, will be the packing ring happen to inlays installs the cone stops to the fitting main body cavity in in the mouth. Pulls the idle talk set the tension bar front end to to pull mandrel on, moves the crank release lever, causes its side to give instead of taking attaches to the pipe on, the rotation locator card, suppresses the crank release lever to cause its not to have to move. This invention release lever enables the fast locking pipeline connection method to each kind of pipeline realization momentary connection. Installs the use extremely to facilitate quickly, saves the time, does not need any construction machines and tools equipment, only must gently as soon as move the bar with the hand lever handle, then realizes the very ideal pipeline connection, also the connection quality is good, also leakproof, may realize to each kind of pipeline momentary connection, especially is suitable to the field operation military temporary pipeline lays down. Because it installs and disassembles similarly is all convenient, its may repeatedly use.
Description
Technical field
The present invention relates to a kind of pipework accessory, particularly relate to the quick locking pipe connecting means of a kind of Lever type.
Technical background
Existing various quick mounting pipe joint is all not ideal.Existing standard JB/T7850-95 " hand folder quick release coupling ", implement to install not quick, because it requires two pipe ends of butt joint turning there emerged a groove, this operates cumbersome at the construction field (site), its major defect is a tie point place rigidity deficiency, if pipeline is unsettled when walking to manage, must add pipe hanging pipe holder at tie point.Existing HG/T21577-94 " special pipe joint fast " implements to install also not quick, because it requires two pipe ends of butt joint also to want turning to there emerged a the groove of supply and marketing nail location, and the last interior hoop sleeve that two tubes can be located to be installed at first, an outer sleeve is installed is again wrapped in interior hoop sleeve outside with the bolt lock ring, its sealing gasket is located on the shroud ring pin of outer sleeve, and sealing configuration is undesirable.Its external form is thick, is difficult to see.Above-mentioned two kinds of quick couplings, (welded steel pipe especially, weld seam often has concavo-convex when the pipe appearance that is connected is very not well-behaved.) time leaks easily.
In view of above-mentioned existing fast-connection pipeline in textural existing defective, the inventor connects the practical experience of enriching that professional work accumulated based on being engaged in pipeline for many years, it is actively studied and innovation, and through constantly designing repeatedly and pilot sample, carry out repeatedly test and constantly improvement, finally creativity and innovation goes out a kind of easy to operate easy grasp, the quick locking pipe connecting means of the Lever type that does not leak.Its intention novelty, the structure uniqueness, install and use very convenient fast, save time, without any need for construction machinery equipment, only with hand is a moving bar bar handle gently, can realize that very desirable pipeline connects, and quality of connection is good, one does not leak yet, can realize quick connection, be particularly useful for the temporary pipeline laying that field army uses various pipelines.Because its installation and removal is all convenient equally, and can use repeatedly.
Summary of the invention
The purpose of this invention is to provide the quick locking pipe connecting means of a kind of Lever type: overcome can not really realizing quick mounting and having the defective of leaking of existing quick coupling product, and a kind of new technology that can realize that really various pipelines connect fast is provided, new structure, it without any need for plant, needs only the pipe connecting method that can realize ideal with the light moving bar bar handle of have gentle hands in fitting operation.
Purpose of the present invention and solve its technical problem underlying and adopt following technical measures to realize.
The quick locking pipe connecting means of aforesaid Lever type.Be that leverage by a crank levers realizes pipeline locking and seal connection structure fast, comprising crank levers, pull bar, axle, tension axle, main pipe body, locking clip, location card, snap ring, packing ring, seal ring.Described crank levers, pull bar, axle are supporting being assemblied on the main pipe body when product export, earlier locking clip, snap ring, packing ring, seal ring are sleeved on tube end in regular turn during installation, again this tube end is inserted in the cavity of main pipe body, make seal ring just in time in the conical seam of setting-in in the main pipe body cavity.The tension hole retaining ring of pull bar front end to the tension axle, is moved crank levers, its side is lost money instead of making money be attached on the pipe, the rotating position card is pushed down crank levers it must not be moved.
The present invention solves its technical problem underlying and can also adopt following technical measures further to realize:
The quick locking pipe connecting means of aforesaid Lever type, wherein said crank levers is to be connected to form by two crank throw handle plates and a circular arc back of the body bar, the fingerboard of crank throw handle plate is provided with axle positioning hole and hinge rivet hole, and the section of circular arc back of the body bar is rectangular plate or circular pin.Crank levers is to make with metallic material.
The quick locking pipe connecting means of aforesaid Lever type, wherein said pull bar is a long strip, and its section is a rectangular plate, and an end of pull bar is provided with two tension holes that get close to mutually, the other end be provided with one with the crank levers rivet hole of hinge mutually, pull bar is to make with metallic material.
The quick locking pipe connecting means of aforesaid Lever type, wherein said axle are sunk screws that has a partial thread, and axle is to make with metallic material.
The quick locking pipe connecting means of aforesaid Lever type, wherein said tension axle are torticollis screws that a partial thread of elbow bend is arranged, and the tension axle is to make with metallic material.
The quick locking pipe connecting means of aforesaid Lever type, several kinds such as that wherein said main pipe body is divided into is straight-through, elbow, threeway, four-way, all main pipe body are cavity, are provided with conical seam in the jointing end portion cavity, and the external cylindrical surface center is provided with the axle screw of two correspondences.Main pipe body is to make with metallic material or duroplasts.
The quick locking pipe connecting means of aforesaid Lever type, wherein said locking clip is the cylindrical body of cavity, inner chamber is conical.Both sides, external cylindrical surface center are provided with the tension axle screw of two correspondences, and the top is provided with a rotating location card.Locking clip is to make with metallic material or duroplasts.
To be an end be positioned at rotating Yi shape bent plate on the locking clip with screw for the quick locking pipe connecting means of aforesaid Lever type, wherein said location card, and location card is to make with metallic material.
The quick locking pipe connecting means of aforesaid Lever type, wherein said snap ring be in separated cylinder tapered collar jaggy, its section is the combination of right-angled trapezium and rectangle, and inner cylindrical surface is provided with a plurality of tooth bars or nail tooth, and snap ring is to make with metallic material or duroplasts or ebonite.
