Abstract
The utility model relates to a groove type mechanical joint without pollution, which is characterized in that the groove type mechanical joint without pollution is composed of two clamping hoops which are provided with ear climbs with open holes. The inner sides of the clamping hoops are provided with grooves. Screw bolts can be fastened by nuts after pass through the holes of the ear climbs. Compared with the existing method, the utility model is fast, simple, reliable and economic. The groove type mechanical joint without pollution can exempt electric welding and has no pollution. The groove type mechanical joint without pollution can absorb noises of pipelines and vibrational transmission, and is easy to repair and maintain. The groove type mechanical joint without pollution does not need special skills in the course of installation, and any body can operate. The fraction defective of man made technique can be dropped to the lowest. The utility model can be quickly installed at a narrow position, and can not be limited by installation places. The budget cost can be controlled easily.
Description
The utility model belongs to the pipe installation technology field, particularly relates to a kind of free of contamination groove type mechanical splice.
Existing pipeline connects general welding, screw thread, the flange connection of adopting.There is the shortcoming of welding slag to the pollution of pipeline in the welding connection, and having relatively high expectations to welding technique; Shortcoming not withstand voltage, easy to leak that the screw thread connection exists; And the flange connection, also must welding, and in zinc-plated pipeline, use flange welding connection, have that need secondary is zinc-plated, the shortcoming of secondary installing; In the copper pipe road, adopt copper flange welding connection, have that difficulty is big, technical requirements is high, pipeline there is the shortcoming of pollution.And above method is subject to the installation site restriction, has shortcomings such as installation rate is slow, operation is many, cost height.In a word, using effect is not fully up to expectations.
The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, can significantly improve the groove type mechanical splice of installation efficiency.
The technical solution of the utility model is, a kind of groove type mechanical splice, and its characteristics are: the clip of being climbed by two ears that have perforate is harmonious and forms, and the inboard of clip is provided with groove, and is after bolt penetrates the hole that ear climbs up out, fastening with nut.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model than existing method come fast, simple and easy, reliable, economical, exempt from electric welding, pollution-free, and the noise that can suction line and the propagation of vibration, maintenance for ease of maintenaince, in installation process, need not special skill, anyly can be competent at per capita, artificial technology reject ratio drops to minimum, also can install rapidly in stenosis, not limited by the installation site, be easy to control estimated cost, can make total engineering expense reduce by 10 to percent 30.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model connects pipeline;
Fig. 3 is the sectional structure schematic representation after the utility model connects pipeline.
Consult Fig. 1, this groove type mechanical splice is harmonious by clip 1,2 and forms, and is equipped with ear on the clip 1,2 and climbs, ear is climbed up the oblong aperture of being offered that is, the neck of corresponding with it bolt 6 also is a rectangle block, bolt 6 penetrate ear climb the back add nut 7 can be fastening, and sliding phenomenon can not take place.Consult Fig. 2,3, wherein clip 1,2 inboards are a groove, and the groove liner is lined with the seal washer 3 that the cross section is " C " shape.Because of the face that is harmonious of clip 1,2 is the inclined-plane,, guarantee that clip has enough pressure to packing ring 3 so this oblique angle to the mode of lock, continues to increase the rolling reduction to packing ring 3 within the specific limits.During connecting tube, earlier on pipe 4,5 ports, offer a groove 8,9, after the edge of clip 1,2 snaps in, tight a bolt 6, nut 7 gets final product.Wherein " C " shape packing ring can form triple leakproofs, at first be that packing ring is attached to the tube end surface, form first leakproof, when secondly being locked clip device, packing ring is subjected to compressing of clip, be adjacent to the tube end surface once again, form the secondary leakproof, have in the pipe besides under the situation of pressure, pressure acts on " C " shape packing ring base and presses to positive pressure of tube end surface direction generation, the pipe internal pressure is big more, and effect is good more.
