Abstract
The utility model provides a self-locking pipe fitting jam which comprises an inner jam, an O-shaped ring and a pipe fitting flange. The self-locking pipe fitting jam is characterized in that a lock pin and a device are arranged on the inner jam, the lock pin is arranged according to the radial direction, the device can enable the lock pin to move on the radial direction, and an annular groove which corresponds to the lock pin is arranged on the inner wall of the pipe fitting flange. The self-locking pipe fitting jam has the beneficial effects that the sealing effect in a product is good, so that the hidden danger of external leakage is avoided, and the use is safe and reliable; the manufacturing difficulty of large pipe fitting plugging devices is reduced; and the installation is convenient and fast.
Description
Technical field: the utility model relates to a kind of blocking device that is used for the operation of pipeline dimension first-aid repair construction, and particularly a kind of self-locking pipe fitting stops up.
Background technique: the existing blocking device that is used for the operation of pipeline dimension first-aid repair construction, shown in accompanying drawing 1, it mainly is made up of interior obstruction 1, O shape circle 2, pipe fitting flange 3, lock(ing) bolt 4, and interior obstruction 1 is locked fixing through lock(ing) bolt 4 behind running tubulars 3.The deficiency that this kind means of fixation in use exists is: 1, need open a plurality of locking apertures that lock(ing) bolt 4 uses that are used on the pipe fitting flange, this makes has the many places seal point on the pipe fitting flange, has bigger leakage hidden danger; 2, manufacturing is difficult, outside flange, will manufacture a plurality of pin-and-holes on the garden; 3, installation process is slower, and the internal thread of lockpin hole possibly cause damage because of the Allen wrench improper use, influences project progress.
Summary of the invention: the purpose of the utility model is to tie up the deficiency that the blocking device of first-aid repair construction operation exists to the existing pipeline that is used for; And a kind of perforate on the pipe fitting flange that do not need is proposed, nothing is leaked hidden danger, self-locking pipe fitting easy and simple to handle, that locking is good stops up.
Can realize the utility model purpose through following technical proposals; A kind of self-locking pipe fitting stops up; Comprise interior obstruction, O shape circle, pipe fitting flange; It is characterized in that, in interior obstruction, be provided with a lock pin and by radial arrangement and can make lock pin, on the pipe fitting flange inner wall, be provided with a circular groove corresponding with lock pin at the device that moves radially.
The said lock pin that makes is meant at the device that moves radially: one is provided with the upper surface that the spiral fluted helical disk stops up in tipping upside down on, and a driving pin one end is inserted in the spiral chute of helical disk, and the other end is inserted in the hole of lock pin; The middle part of helical disk is provided with a cubic through hole.
Take off lock for preventing that lock pin from moving, in interior obstruction, be provided with the fastening screw trip bolt of a pair of lock pin locking.
The effect of the utility model is: 1, good sealing effect in the product, can there be the hidden danger of external leakage, and safe and reliable; This is; This device be device in the inner obstruction to self-locking own, it does not need on the pipe fitting flange, to open locking aperture, makes the pipe fitting flange keep whole integrity; Stopped to exist the hidden danger of external leakage, made it safe and reliable; 2, reduced the manufacture difficulty of big pipe fitting blocking device; 3, easy for installation, quick, only need rotate square axis when this is to install and can accomplish down the work of stopping up through tightening fastening screw trip bolt.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is the sectional structure schematic representation of existing blocking device;
Accompanying drawing 2 is the sectional structure schematic representation of the utility model;
Accompanying drawing 3 is the worm's eye view of helical disk 8 in the accompanying drawing 2.
Embodiment:
Referring to accompanying drawing 1,2,3, a kind of self-locking pipe fitting stops up, and it is made up of interior obstruction 1, O shape circle 2, pipe fitting flange 3, lock pin 4, fastening screw trip bolt 5, gland 6, driving pin 7, helical disk 8.In interior obstruction 1, be provided with a groove by radial arrangement, lock pin 4 is located in the groove; One can make lock pin 4 be connected with lock pin 4 at the device that moves radially, and the composition of this device is: one is provided with spiral fluted helical disk 8 tips upside down on interior 1 the upper surface that stops up, and driving pin 7 one ends are inserted in the spiral chute of helical disk 8, and the other end is inserted in the hole of lock pin 4; The middle part of helical disk 8 is provided with a cubic through hole, and helical disk 8 is through square axis 9 rotations; Pipe fitting flange 3 inwalls are provided with a circular groove corresponding with lock pin 4, and lock pin 4 can be inserted into and internally stop up 1 locking in the circular groove; Take off lock for preventing that lock pin 4 from moving, in interior obstruction 1, be provided with the fastening screw trip bolt 5 of a pair of lock pin 4 lockings; In being located at, O shape circle 2 between obstruction 1 and the pipe fitting flange 3, plays the effect of stopping up 1 upper and lower medium in intercepting.Gland 6 in interior obstruction 1, plays the fixedly effect of helical disk 8 through screw.
The operation procedure of this device is: after interior obstruction 1 went downwards in the pipe fitting flange 3, rotation square axis 9 drove helical disk 8 and turns clockwise; Helical disk 8 drives lock pin 4 through driving pin 7 and stretches out, and gets in the circular groove in the pipe fitting flange 3, and stopping up 1 in blocking can not move up and down; Fastening screw trip bolt 5 is tightened after lock pin 4 puts in place; Lock pin 4 can not be passed in and out, stop up 1 safety in ensureing, the work of following obstruction is accomplished.
Claims (3)
1. a self-locking pipe fitting stops up; Comprise interior obstruction, O shape circle, pipe fitting flange; It is characterized in that, in interior obstruction, be provided with a lock pin and by radial arrangement and can make lock pin, on the pipe fitting flange inner wall, be provided with a circular groove corresponding with lock pin at the device that moves radially.
2. stop up by the described self-locking pipe fitting of claim 1; It is characterized in that; The said lock pin that makes is meant at the device that moves radially: one is provided with the upper surface that the spiral fluted helical disk stops up in tipping upside down on, and a driving pin one end is inserted in the spiral chute of helical disk, and the other end is inserted in the hole of lock pin; The middle part of helical disk is provided with a cubic through hole.
