Abstract
Disclosed is a novel pressure-resistant sealing and connecting pipe structure which comprises a shell, a seal ring, a pressure-resistant thimble, a plurality of steel balls, a nut and a pipe, wherein, one end of the pipe is inserted in the spile chamber of the shell, the seal ring is nested on the outerwall of the pipe and is disposed in the chamber of the shell, the pressure-resistant thimble is also nested on the outer wall of the pipe and disposed at one end of the seal ring, one end of the pressure-resistant thimble is provided with a plurality of radial holes, the steel balls are arranged in the radial holes respectively, the nut facilitates the pressure-resistant thimble, the steel balls are nested in the chamber of the nut under the help of the nut, and are locked up by the internal screw thread of the nut and the external screw thread at the end of the shell.
Description
A kind of novel pressure-resistant seal connecting tube substructure relates to pressure-resistant seal and connects pipe
Technical field.
The extruding type pipe fitting that Japan Five continents envelope pressure pipe part Co., Ltd produces adopts pipe to peg graft, the sealing of O type circle, dedicated hydraulic clamp pipe locking linkage structure.Though it is simple in structure, materials are also few, and aspects such as the accuracy of manufacturing of pipe and joint and construction and installation are all had high requirements.And the job site must be equipped with the dedicated hydraulic locking pliers.It is just non-disconnectable that another defective of this structure is that in a single day pipeline installs.As seepage occurring because of some reason causes pipeline, just the sawing of seepage pipeline section can only be fallen, reinstall section of a pipe again.
Hong Kong east flourish building material engineering Co., Ltd releases obtains the edible water pipe of stainless steel that state's patent such as the U.S., Japan and European alliance check and approve bulletin.Though its pressure-resistant seal switching performance is better.But also exist when installing need with special device the desired location spinning of pipe end together in concave ring groove.Do like this and produce certain bottleneck effect.Also need be with special special spanner when tightening swivel nut.Its appearance and modeling is also more ugly.
Utility model patent---a kind of pressure-resistant seal connecting tube substructure (patent No.: though it is effective ZL99204509.6) to have a pressure-resistant seal, mounting or dismounting easily, plurality of advantages such as the simple and cost of manufacturing process is low.But this structure can not be applicable to the connection of tubule footpath pipe.
The purpose of this utility model is to provide a kind of pressure-resistant seal performance excellence, and is simple in structure, and the mounting or dismounting pipeline is convenient, and appearance and modeling U.S. adopts inserting mode to be connected with pipe, can be applicable to the novel pressure-resistant seal connecting tube substructure that tubule footpath pipe connects.
The purpose of this utility model is achieved in that by housing (1), seal ring (2), roof pressure cover (3), steel ball (5), nut (4), in the novel pressure-resistant seal connecting tube substructure that pipe (6) is formed, seal ring is to be enclosed within institute to be connected the tube outer wall end with the roof pressure cover, and places the housing inner chamber successively.Several steel balls are to be positioned over respectively in several radial holes of roof pressure cover.Nut is placed in its inner chamber with roof pressure cover and several steel balls, and is screwed by the internal thread of nut and the outside thread of shell end.
In the process of tightening; At first the inner conical surface of nut is rolling friction with the sphere of several steel balls and contacts, and forces roof pressure interplanting axial displacement.Thereby axially the roof pressure seal ring makes seal ring produce the axial compression radial expansion.To fill up compacting by the Seal cage that the roof pressure end face of housing inner chamber, tube outer wall and roof pressure cover is formed, make it to form good pressure-resistant seal state.This moment, seal ring will stop the axial displacement of roof pressure cover and several steel balls gradually.In the case, several steel balls just under the effect of nut inner conical surface radial component, are done radial displacement along several radial holes of roof pressure cover, and the compressing tube wall produces deformation, finally make and form several radially pits on the tube wall.Along with nut continue tighten, after several steel ball radial displacements put in place, finally enter in the straight hole section of nut.And the rear side end face of roof pressure cover is contacted with the inner side end of nut.At this moment several steel balls play a part the locking pipe in several radially pits of tube wall.Under this state, the utility model with have higher anti-pressure being connected of pipe and expand to take off and take off ability with tension.And have and prevent the function of pipe with respect to joint rotation.
The utility model compared with prior art has pressure-resistant seal performance excellence, and is simple in structure, and mounting or dismounting are convenient, and are low to the required precision of pipe connecting end, can be applicable to that tubule directly connects, easy to manufacture, low cost and other advantages.
The utility model has following accompanying drawing:
Fig. 1, Fig. 2 are sectional arrangement drawing of the present utility model.
Respectively marking sequence number among Fig. 1 is expressed as follows respectively:
1. housing 2. seal rings 3. roof pressures overlap 4. nuts, 5. steel balls, 6. pipes
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is in the sectional arrangement drawing that original state is installed for the utility model.At this moment, an end of pipe (6) is inserted in the cannula lumen of housing (1); Seal ring (2) is placed in the outer wall of pipe (6), and places the inner chamber of housing (1); Roof pressure cover (3) also is placed in the outer wall of pipe (6), and places an end of seal ring (2); One end of roof pressure cover (3) has several radial holes, and several steel balls (5) place several radial holes of roof pressure cover (3) respectively; Nut (4) is placed in its inner chamber with roof pressure cover (3) and several steel balls (5), and is screwed by the internal thread of nut (4) and the outside thread of housing (1) end.Several steel balls (5) are the rolling friction contact condition with the inner conical surface of nut (4).
Fig. 2 is in the sectional arrangement drawing that done state is installed for the utility model.At this moment, the outside thread of the internal thread of nut (4) and housing (1) end screws fully.Seal ring (2) has made the good pressure-resistant seal state of formation between pipe (6) and housing (1) under the effect of axial roof pressure power.Several steel balls (5) have been pressed in several radially pits of pipe (6) outer wall, and place the garden post inner chamber of nut (4).Steel ball (5) plays the effect of locking pipe.
Claims (1)
1. novel pressure-resistant seal connecting tube substructure, it is characterized in that the novel pressure-resistant seal connecting tube substructure be made up of housing (1) seal ring (2), roof pressure cover (3), nut (4), steel ball (5), pipe (6), an end of pipe (6) is inserted in the cannula lumen of housing (1); Seal ring (2) is placed in the outer wall of pipe (6), and places the inner chamber of housing (1); Roof pressure cover (3) also is placed in the outer wall of pipe (6), and places an end of seal ring (2); One end of roof pressure cover (3) has several radial holes, several steel balls (5) place several radial holes of roof pressure cover (3) respectively, nut (4) is placed in its inner chamber with roof pressure cover (3) and several steel balls (5), and is screwed by the internal thread of nut (4) and the outside thread of housing (1) end.
