Abstract
The utility model provides a split type pipe connection spare, including the coupling, the C type ring, cartridge flexible pipe between coupling and C type ring, lock female and screwed pipe, be equipped with the inner tube sealing washer between coupling and the flexible pipe, be equipped with the end sealing washer between coupling front portion and the screwed pipe, be equipped with the internal thread with the external screw thread matched with of screwed pipe on the lock female, wherein the tapering beta of the excircle surface of tip is 10 behind the C type ring, the tapering alpha of the locking surface of lock female is 10, the width of C type ring is 12mm, and the internal surface is equipped with four muscle, the tapering gamma of the excircle surface of tip is 35 before the coupling. The utility model discloses split type union coupling connects reliably, and simple to operate can effectively solve the seepage problem.
Description
Technical field
The utility model is put it briefly and is related to a kind of link, relates in particular to a kind of split type tubular union that flexible pipe is connected with threaded pipe that is used for.
Background technique
In being connected of aluminium-plastic composite pipe (PAP), crosslinked polythene pipe flexible pipes such as (PEX) and threaded pipe, because the thermal expansion coefficient of plastics and metal is different, when so temperature variation is bigger, seepage easily takes place in tube and tube spare joint, the tapering of the C type ring rear end of present FERRULETYPE threaded connector is excessive, and the radial contraction amount of deformation is not enough, when the amount of deformation of tubing is excessive, still the seepage phenomenon can take place, and existing tubular union bothers very when mounted.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of split type tubular union reliable, easy for installation that connects is provided, and it can effectively solve leakage problems.
The split type tubular union of the utility model, comprise pipe joint, C type ring, be inserted into the flexible pipe between described pipe joint and the C type ring, locknut and threaded pipe, seal of tube circle in being provided with between pipe joint and the flexible pipe, be provided with the termination seal ring between pipe joint front portion and the described threaded pipe, described locknut is provided with the internal thread that matches with the outside thread of threaded pipe, the tapering β of the outer round surface of wherein said C type ring rearward end is 10 °, the tapering α of the locking face of described locknut is 10 °, the width of described C type ring is 12mm, and internal surface is provided with four road muscle, and the tapering γ of the outer round surface of pipe joint front end is 35 °.
The split type tubular union of the utility model, wherein said flexible pipe is an aluminium-plastic composite pipe.
The split type tubular union of the utility model, wherein said flexible pipe are the crosslinked polythene pipes.
The advantage and the good effect of split type tubular union described in the utility model are: it adopts the branch body structure, can directly be connected with the threaded pipe of radiator, thermostat valve, water collecting and diversifying device etc., and is easy for installation; Because the tapering α of the outer round surface of C type ring rearward end is 10 °, the tapering β of the locking face of locknut is 10 °, so when locknut is locked, increase radially coupling mechanism force, simultaneously because the width of C type ring is 12mm, locking place area of contact is increased, increased pressure under the equal pressure conditions, improved frictional force, make connection more reliable, the tapering γ of the outer round surface of pipe joint front end is 35 °, has also increased the reliability that connects, so pipe joint link described in the utility model can prevent the generation of seepage phenomenon well.
Other details of the split type tubular union of the utility model and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is the broken section structural representation under the split type tubular union installment state described in the utility model.
Embodiment
The split type tubular union of the utility model as shown in Figure 1 comprises pipe joint 1, C type ring 4, locknut 5 and threaded pipe 6.Be fitted with flexible pipe 3 between pipe joint 1 and the C type ring 4, wherein flexible pipe 3 is crosslinked polythene pipes, it also can be the flexible pipe of other kinds, as aluminium-plastic composite pipe etc., seal of tube circle 11 in being provided with between pipe joint 1 and the flexible pipe 3, be provided with seal ring 2 between threaded pipe 6 and pipe joint 1 front portion, sealing circle 2 can increase sealing.Locknut 5 is provided with the internal thread that matches with the outside thread of threaded pipe 6.Outer round surface in C type ring 4 rearward end, be that the tapering α that has pawl 9 one ends on the body is 10 °, the locking face of locknut 5, the tapering β of face of matching with C type ring 4 rearward end outer round surface when promptly installing is 10 °, and the width of C type ring 4 is 12mm, and is provided with four road muscle at C type ring 4 internal surfaces, during locking, it can increase radially coupling mechanism force, and the tapering γ of the outer round surface of pipe joint 1 front end is 35, increases the reliability that connects.When the amount of deformation of tubing exceeds the distortion that tubing produces because of expanded by heating, just can effectively prevent seepage.
When flexible pipe 3 is connected with pipe joint 1, flexible pipe 3 is enclosed within on pipe joint 1 band shape pawl 9 connecting ends, move axially by tightening locknut 5 generations, the 10 ° of taperings in locknut 5 rear ends press C type ring 4 to produce radially tightening force, thereby make flexible pipe 3 generation radial deformations compress seal ring 11 and play seal action, and flexible pipe 3 is fixed on the pipe joint 1 firmly.Compress the O RunddichtringO simultaneously and make it threaded pipe sealing joint with radiator etc.
Pipe joint link described in the utility model can be applicable to any end or the above pipe fittings such as the above demultplexer joint of straight joint, elbow connection, three-way union, threeway that connect flexible pipe of an end.
When the utility model is installed, earlier locknut 5, C type ring 4 are enclosed within on the flexible pipe 3,, locknut 5 and the threaded pipe on the radiator are tightened flexible pipe mouth of pipe full circle with special-purpose rounding device again, the pressure testing ne-leakage gets final product.
