Abstract
The utility model relates to an extrusion type linker for the liquid pipes which mainly comprises rubber sleeves, extrusion seats and pressing nuts arranged inside flutes on the joint ends; wherein, the contact areas between the extrusion seats and the rubber sleeves are plane; the extrusion seats are in line contact with the pressing nuts; pipes which are connected are through the rubber sleeves and the extrusion seats; the pressing nuts are tightened to ensure the rubber sleeves deformed to fill the spacing between the pipes which are connected with the joint, thereby avoid liquid leakage from the pipes. When certain chemical liquid or high pressure liquid flows through the pipes, the sealing rubber is replaced with soft metal material. The utility model is characterized in convenient utilization, reliable connection, easy maintenance and so one and is fit for the connecting device for various liquid pipes.
Description
The utility model relates to the connection set that a kind of fluid line is used, and especially makes the pipe jointer of its closed conduit interface by external force crush seal rubber cushion.
Chinese patent ZL99233802.6 specification discloses a kind of self-locking pipe jointer, promptly open cascade groove one at the inner chamber of connector, and settle a cone rubber cover, after connected pipe passes rubber sleeve, thereby the pressure that the fluid that overflows in this pipeline possesses himself forces rubber sleeve tightly to be pressed in to be played self-locking closure on the outer wall of connected pipe insertion portion and prevents the effect that the pipeline inner fluid overflows at the pipe joint place.The seal degree of being not difficult to find out this self-locking pipe jointer depends on the pressure of pipeline inner fluid and the elastic force of cone rubber cover self, though but instead of part is threaded and flange connecting apparatus, but owing to exist situations such as ageing of rubber and hydrodynamic pressure be too small or excessive all can cause the pipeline connection failure, reliability is relatively poor.
The purpose of this utility model provides a kind of delicate structure, and is easy to use, easy to repair, can connect the squeeze-type pipe jointer that various wall thickness (particularly thin-walled) metal material hard tube can connect rubber pipe, plastic tube and aluminium plastic composited tube again.
For achieving the above object, pipe jointer of the present utility model, adopt the extruding type structure, promptly between the inwall of joint and connected tube, a ring-shaped rubber cover is set, put into an extruding base simultaneously, the end that base contacts with fastening nut is taper, contacts to be the line contact, be connected by tightening the active pipeline that gland nut forces rubber sleeve generation deformation to seal the gap between connected pipe and the connector, thereby prevent that the pipeline inner fluid from overflowing.
Compare with present technology, the utility model has following characteristics:
1. firm and reliable connection forces sealing rubber cover deformation owing to adopt initiatively to push, and need not consider that pipe fluid pressure and rubber are because of the aging problem that lost efficacy.
2. applicability is wide, is particularly suitable for connecting the thin-wall stainless steel tubing that can't the car silk connects.
3. easy to use, easy to repair, it is convenient to construct.
The utility model pipe jointer is suitable for the connection set as various fluid lines.
Fig. 1 is the structural drawing of the utility model squeeze-type pipe jointer straight coupling.
Fig. 2 is the A-A sectional view of the utility model extrusion pipe connector straight coupling.
Fig. 3 is second kind of working state structure figure of the utility model squeeze-type pipe jointer straight coupling.
Describe concrete structure of the present utility model and working principle in detail below in conjunction with accompanying drawing.
As shown in the figure, on the inwall of two of joint 1, respectively open a groove, one ring-shaped rubber cover 3 is housed in the groove, the degree of depth of groove will be a bit larger tham the length of rubber sleeve 3, place an extruding base 4 again on rubber sleeve 3, extruding base 4 is the plane with the surface of contact of rubber sleeve, and extruding base 4 is the conical surface with the surface of contact of gland nut 2, perhaps gland nut 2 is the conical surface with the surface of contact of extruding base 4, and making the contact between them is the line contact.The extruding base can be transformed into a faced washer 6 and adds the gland nut 2 on a taper top or be transformed into gland nut 2 compositions that a taper washer 7 adds top, a plane.
Working principle is as follows: earlier gland nut 2 is enclosed within on the connected pipe 5, again rubber sleeve 3 and extruding base 4 are placed in the groove of joint 1, because the utility model squeeze-type pipe jointer and be Spielpassung between the connecting leg road 5, so connected pipe 5 passes extruding base 4 and rubber sleeve 3 at an easy rate and inserts in the joint 1, tighten gland nut 2 then, because extruding base 4 is the line contact with contacting of gland nut 2, if therefore by tightening the pushing force that extruding base 4 passes to the axial direction of advocating of rubber sleeve 3.Deformation must take place after being subjected to pushing compressing in rubber sleeve 3, and it is gapped that it can fill the institute of 5 of full joint 1 and connected pipes, and gland nut 2 twists tightly more, and the pressure of rubber sleeve 3 butt joints 1 and connected pipe 5 is big more, thereby seals tightly more.Thereby playing initiatively, closed conduct prevents the effect that fluid overflows.
When the fluid in the connected pipe was some special fluids, its sealing rubber cover 3 can substitute with soft metal material and plastics, as aluminium, tin, wrought aluminium, anti-rotten plastics etc.
Claims (3)
1, a kind of squeeze-type pipe jointer comprises joint (1), gland nut (2), connected pipe (5), it is characterized in that: the groove at the inwall of joint (1) is equipped with rubber sleeve (3) and extruding base (4).
2, a kind of squeeze-type pipe jointer according to claim 1 is characterized in that: extruding base (4) is the plane with the surface of contact of rubber sleeve (3), and extruding base (4) is taper with the surface of contact of gland nut (2).
3, squeeze-type pipe jointer according to claim 1 and 2 is characterized in that: extruding base (4) can be replaced by faced washer (6) and taper washer (7).
