Abstract

The utility model relates to a PE pipeline electric melting sleeve barrel leaking slit plugging type emergency repair interface, which is used to seal the joint air leaking portion between a PE pipeline and an electric melting sleeve barrel. The emergency repair interface is characterized in that the emergency repair interface comprises two O-shaped packing rings which are respectively arranged on joints of two ends of the electric melting sleeve barrel and two pressure rollers which are respectively formed through engaging two binary roller plates, wherein the two pressure rollers are respectively pressed outside the two O-shaped packing rings, the emergency repair interface also comprises N binding bolts which are traversed through the two pressure rollers, wherein the two pressure rollers are tensed and fixed through the N binding bolts, wherein the N is a natural number. The emergency repair interface has simple and practical structure, low installing requirements, low using cost, reliable sealing and rapid and convenient operation, and can satisfy the demands for emergently repairing and gas-inlaying PE pipes such as steel pipes and cast iron pipes and guarantees necessary conditions for safely providing air.

Description

A kind of PE pipeline electric smelting sleeve gap leakage plugging type repairing interface
Technical field
The utility model relates to the mechanical interface of not getting angry, and relates in particular to a kind of PE pipeline electric smelting sleeve gap leakage plugging type repairing interface.
Background technique
Along with reform and opening-up, the Shanghai gas industry strengthens the dynamics of carrying out using PE (polyethylene) pipe delivery of fuel gas, and the Shanghai following gas pipeline use amount of area 0.4Mpa rises day by day, so far, is laid with more than the several hundred kilometers.Wherein, the application of PE tubing electric capacity sleeve is particularly extensive, but, because the PE pipe construction is had relatively high expectations to the material of electric heating molten technology, electric heating melting apparatus and tubing member, therefore,, will make to have the slit between electric capacity sleeve cylindrical shell and body, thereby cause leakage hidden danger during not up to standard or improper use when the quality of production.
In sum, the gas leakage of the PE gas pipeline which kind of reason is drawn all is not allow the serious accident that takes place, therefore leaks in case take place, and must rush to repair fast and effectively.Yet at present, existing P E pipe repairing accessory user cost height, poor practicability, therefore, with regard to present industry present situation, what be short of most is ripe effectively damage repair technology and handy repairing means and repairing parts.
The model utility content
In order to overcome the problems referred to above, the utility model aims to provide a kind of PE pipeline electric smelting sleeve gap leakage plugging type repairing interface, and is simple with implementation structure, easy to operate, cost is low, can be issued to the better seal effect in simple sealed environment, is applicable to the purpose of quick repairing.
A kind of PE pipeline electric smelting sleeve gap leakage plugging type repairing interface described in the utility model is used for the shutoff of the seam air-leak section of PE pipeline and electric smelting sleeve, and it is characterized in that: it comprises:
Two O RunddichtringOs that respectively place electric smelting sleeve two ends seam crossing and two take turns the pinch roller that the sheet engagement forms double by two respectively, and described two pinch rollers are pressed on the outside of described two O RunddichtringOs respectively;
N is located in the clamping bolt between described two pinch rollers, and described two pinch rollers are strained and fixed by a described N clamping bolt, and wherein, N is a natural number.
In above-mentioned PE pipeline electric smelting sleeve gap leakage plugging type repairing interface, described each pinch roller is inboard along being circumferentially with a back-up ring plate, and the inwall of this ring washer plate is squeezed on the O RunddichtringO.
In above-mentioned PE pipeline electric smelting sleeve gap leakage plugging type repairing interface, take turns sheet engagement place brachycephaly bolt double for described two.
In above-mentioned PE pipeline electric smelting sleeve gap leakage plugging type repairing interface, described two O RunddichtringO materials are nitrile butadiene rubber, and hardness is 65 ° ± 5 ° of Shao's formulas.
Owing to adopted above-mentioned technical solution, the utility model is by after tightening clamping bolt, can make seal ring be close to electric smelting sleeve two ends seam crossing, and because the seal ring top is provided with baffle plate, therefore, during the inside crush seal circle of pinch roller, seal ring can not move up, thereby reaches hermetic effect.In addition, the material of seal ring and the design of hardness thereof make its whole sealing effect better.After using this PE pipeline electric smelting sleeve gap leakage plugging type repairing interface, make the maximum of pipeline bear pressure and reach more than the 0.6Mpa, and guarantee not leak fully.The utility model is simple and practical, and installation requirement is low, and user cost is low, and sealing is reliable, operate quick and conveniently, can satisfy the PE pipe and comprise steel pipe, cast iron tube repairing or the needs of being with gas to splice, provides necessary condition for guaranteeing safe way.
Description of drawings
Fig. 1 is that the utility model slit plugging type repairing interface is installed in the structural representation on PE pipeline and the electric smelting sleeve.
Fig. 2 is the side view of Fig. 1.
Embodiment
As shown in Figure 1, referring to Fig. 2, the utility model, that is: a kind of PE pipeline electric smelting sleeve gap leakage plugging type is rushed to repair interface, comprise: two O RunddichtringOs 3, two pinch rollers 4, a N clamping bolt 5 (N is a natural number), wherein, two O RunddichtringO 3 materials are nitrile butadiene rubber, hardness is 65 ° ± 5 ° of Shao's formulas, respectively places the seam crossing at PE pipeline 1 and electric smelting sleeve 2 two ends.Two pinch rollers 4 are taken turns sheet 41 engagements double by two respectively and are formed, and fix with brachycephaly bolt 6 in the engagement place, and two pinch rollers 4 are pressed on the outside of two O RunddichtringOs 3 respectively.
Wear N clamping bolt 5 between two pinch rollers 4, and two pinch rollers 4 are strained and fixed by N clamping bolt 5.
Each pinch roller 4 is inboard along being circumferentially with a back-up ring plate 7, and the inwall of ring washer plate 7 is squeezed on the O RunddichtringO 3.
In the utility model, the concrete parameter in two O RunddichtringO 3 cross sections is according to the bore design of PE pipeline 1, and for example, when the PE pipe diameter was 200mm, the diameter of section of O RunddichtringO was that 8mm, circle footpath are 190mm.During installation, but angle cuts two O RunddichtringOs 3 for about 45 °, be nested into respectively on the PE pipeline 1 of electric smelting sleeve 2 both sides, under extended state, use binder, such as efficient 502 glue, the bonding formation of otch is placed in O RunddichtringO full circle on the two ends PE pipeline 1, and it is pushed the position, slit of electric smelting sleeve 2 and PE pipeline 1 connecting part.In the utility model two take turns the mechanical planarization degree that sheet 41 engagements form for double and be better than 0.5mm.
In sum, the utility model is simple and practical, and installation requirement is low, and user cost is low, and sealing is reliable, operate quick and conveniently, can satisfy the PE pipe and comprise steel pipe, cast iron tube repairing or the needs of being with gas to splice, provides necessary condition for guaranteeing safe way.
