At present, the clean out type occurring on market mainly contains: 1. clean out main body and tubing are adhesive means; 2. clean out main body and tubing directly adopt screw thread to tighten; 3. the clean out of the better simply spigot-and-socket of dismountable structure.But above-mentioned clean out is comparatively simple, it connects compact not, dismantle more loaded down with trivial detailsly, and inconvenience is installed.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of dismountable PVC draining clean out, and the clean out of this structure is detachable, and it can firmly be locked on tubing simultaneously, prevents from being washed open by water.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of dismountable PVC draining clean out, comprise clean out main body, be located at sealing ring and pressure pad in clean out main body, wherein, clean out also comprises clean out nut and hold-down ring, and clean out spiro cap is located at clean out main body outside and is rotatably connected with clean out main body; Hold-down ring is located in clean out nut, and the inside of hold-down ring is provided with tooth-shape structure.
First clean out nut, hold-down ring, pressure pad, sealing ring are nested on pvc pipe material successively, again pvc pipe material is inserted in clean out main body. finally tighten clean out nut, nut can move forward and push hold-down ring, outer wall has been held the hold-down ring meeting reduced inner diameter of openning and has been pushed down tubing, whole clean out can be locked on pvc pipe material tightly like this.Due to sealing ring being housed, can effectively prevent drainage.The target of this programme designs a clean out exactly: 1. can be convenient for people to mounting or dismounting and use, not destroy product or tubing; 2. can guarantee sealing performance; 3. can lock securely tubing.
Further, described sealing ring is O RunddichtringO or pawl RunddichtringO.This programme is dismountable socket joint mode, is furnished with sealing ring, by crush seal circle, prevents from leaking.Small-sized (dn75 and following) adopts the O RunddichtringO with tail, and large specification (dn110 and more than) adopts pawl RunddichtringO.
Further, described tooth-shape structure is inverted triangle toothing.This clean out has unique locking mechanism, has good locking function.Locking mechanism comprises clean out nut, hold-down ring.Hold-down ring inwall is with inverted triangle tooth.Nut can move forward and push hold-down ring, and outer wall has been held the hold-down ring meeting reduced inner diameter of openning and pushed down tubing, and hold-down ring inwall also can prevent from skidding with inverted triangle tooth simultaneously, whole clean out can be locked on pvc pipe material tightly like this.
Further, clean out nut outer wall is provided with a plurality of groove structures.When this groove structure is user-friendly to, by instruments such as nut runners, clean out nut is tightened or unclamped.
Compared with prior art, beneficial effect is: this clean out of the utility model adopts dismountable mode, and tubing socket joint is in clean out main body.This clean out, with locking member, has locking function, can firmly be locked on tubing, prevents from being washed open by water.Feature has: 1. mode is dismountable socket joint mode; 2. adopt press seal circle to prevent from leaking; 3. with locking member: hold-down ring, clean out nut, have locking function.Dismountable socket joint mode just can be convenient for people to install and remove clean out, and can avoid adhesive type clean out when removing, to destroy the situation of product or pipeline.By press seal circle, can effectively prevent drainage.The fixed form of this clean out is unique, adopts nut extruding hold-down ring, and hold-down ring is extrude tubes again, can pin tightly tubing like this.

The specific embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As Figure 1-4, a kind of dismountable PVC draining clean out, comprise clean out main body 1, be located at sealing ring 2 and pressure pad 3 in clean out main body 1, wherein, clean out also comprises clean out nut 4 and hold-down ring 5, and clean out nut 4 is sheathed on clean out main body 1 outside and is rotatably connected with clean out main body 1; Hold-down ring 5 is located in clean out nut 4, and the inside of hold-down ring 5 is provided with tooth-shape structure.
In Fig. 1, described sealing ring 2 is O RunddichtringO, and the present embodiment is dismountable socket joint mode, is furnished with sealing ring 2, by crush seal circle 2, prevents from leaking.Small-sized (dn75 and following) adopts the O RunddichtringO with tail.
In Fig. 2, tooth-shape structure is inverted triangle toothing.This clean out has unique locking mechanism, has good locking function.Locking mechanism comprises clean out nut, hold-down ring.Hold-down ring inwall is with inverted triangle tooth.Nut can move forward and push hold-down ring, and outer wall has been held the hold-down ring meeting reduced inner diameter of openning and pushed down tubing, and hold-down ring inwall also can prevent from skidding with inverted triangle tooth simultaneously, whole clean out can be locked on pvc pipe material tightly like this.
In Fig. 3, clean out nut 4 outer walls are provided with a plurality of groove structures.When this groove structure is user-friendly to, by instruments such as nut runners, clean out nut 4 is tightened or unclamped.
The concrete erection sequence of product is: first clean out nut 4, hold-down ring 5, pressure pad 3, sealing ring 2 are nested into successively on tubing 6 → pvc pipe material 6 are inserted into again 1 li of clean out main body → finally tighten clean out nut 4.Nut 4 can move forward and push hold-down ring 5, and outer wall has been held the hold-down ring of openning can reduced inner diameter and push down tubing 6, whole clean out can be locked on pvc pipe material tightly like this, product (small-sized) after assembling as shown in Figure 1.The part explosive view of product solid is shown in Fig. 3.
