Abstract
The utility model discloses a kind of device for steel pipe welding with pressure, comprise channel-section steel, be provided with band iron and several pads in channel-section steel, channel-section steel be provided with several holes, each hole be connected with nut, nut is provided with screw rod.A kind of device for steel pipe welding with pressure is provided with channel-section steel, steel pipe tube wall is welded to by channel-section steel, by tightening screw rod, pressure is forced on band iron that Lou eye, trachoma and weld seam fine fisssure tube wall are placed, prevent flowing water pressure in pipeline from acting on Lou eye, trachoma and weld seam fine fisssure place, flowing water affects weld job, and stops pipeline leakage eye, trachoma and weld seam fine fisssure place to leak by impressed pressure, can complete weld job smoothly.Welded and confirmed firmly, turned on screw rod, the impact dismounting of the channel-section steel of spot welding caused pipeline is little.Without the need to draining of cutting off the water, decrease operation sequence, drainage system is run without impact, shortens Lou eye, trachoma and weld seam fine fisssure processing time greatly, improve operating efficiency.
Description
Technical field
The utility model belongs to pipeline maintenance technical field, relates to a kind of device for steel pipe welding with pressure.
Background technology
Pipeline in use, can produce Lou eye, trachoma and weld seam fine fisssure, in order to not affect normal use, produce and leak eye, trachoma and the palpus process welding of weld seam fine fisssure place, because of the effect of pipeline internal water pressure, must stop plumbing, etc. after pipeline pressure release water drains, can weld job be implemented.
Utility model content
The purpose of this utility model there are provided a kind of device for steel pipe welding with pressure, and this device can carry out weld job when not cutting off the water.
The technical scheme that the utility model adopts is, a kind of device for steel pipe welding with pressure, comprises channel-section steel, is provided with band iron and several pads, channel-section steel is provided with several holes, each hole is connected with nut, nut is provided with screw rod in channel-section steel.
Feature of the present utility model is also,
Each hole is welded with nut.
Pad is play the soft materials of suppressing sealing function.
Band iron is the narrow strip of band radian.
The length of screw rod is greater than the height of channel-section steel.
The beneficial effects of the utility model are: a kind of device for steel pipe welding with pressure is provided with channel-section steel, steel pipe tube wall is welded to by channel-section steel, by tightening screw rod, pressure is forced on band iron that Lou eye, trachoma and weld seam fine fisssure tube wall are placed, prevent flowing water pressure in pipeline from acting on Lou eye, trachoma and weld seam fine fisssure place, flowing water affects weld job, and stops pipeline leakage eye, trachoma and weld seam fine fisssure place to leak by impressed pressure, can complete weld job smoothly.Welded and confirmed firmly, turned on screw rod, the impact dismounting of the channel-section steel of spot welding caused pipeline is little.Without the need to draining of cutting off the water, decrease operation sequence, on water supply and sewage without impact, shorten Lou eye, trachoma and weld seam fine fisssure processing time greatly, improve operating efficiency, solve and can not to cut off the water draining and complete the problem of Lou eye, trachoma and the process of weld seam fine fisssure again under objective condition restriction.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of device for steel pipe welding with pressure of the utility model;
Fig. 2 is the using state figure of a kind of device for steel pipe welding with pressure of the utility model.
In figure, 1. channel-section steel, 2. hole, 3. nut, 4. screw rod, 5. pad, 6. band iron.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of device for steel pipe welding with pressure, as shown in Figure 1, comprises channel-section steel 1, is provided with band iron 6 and several pads 5, channel-section steel 1 is provided with several holes 2, each hole 2 is connected with nut 3, nut 3 is provided with screw rod 4 in channel-section steel 1;
Each hole 2 is welded with nut 3;
Pad 5 suppresses the soft materials of sealing function for playing, be beneficial to that band iron 6 and tube wall are further airtightly to be welded;
Band iron 6 is the narrow strip of band radian, its size shape should meet and shelters from pipeline completely and leak eye, trachoma and weld seam fine fisssure place, meet again and will leave enough spaces between channel-section steel 1, also to meet simultaneously and adapt with steel pipe tube wall radian, tightly can weld, be beneficial to the tightness of weld job and welding;
The length of screw rod 4 is greater than the height of channel-section steel 1, to increase external pressure by tightening extruding steel pipe tube wall.
Beat several holes 2 above channel-section steel 1, how many, size, seepage area size how many according to leakage eye in hole 2 are determined, leak that eye is many, large, seepage region is comparatively large, then suitably can increase the quantity of punching 2, otherwise can suitably reduce, to meet reinforcing band iron 6 for needs.
The using method of a kind of device for steel pipe welding with pressure of the utility model is: as shown in Figure 2, first channel-section steel 1 is welded to steel pipeline and has leakage eye, directly over trachoma and weld seam fine fisssure place, pad 5 is placed on pipeline and leaks eye, trachoma and weld seam fine fisssure place, in placement pad 5 region, place band iron 6 and live with hand temporarily fixing, band iron 6 covers completely places pad 5 region, the screw rod 4 of inserting on nut 3 is tightened downwards simultaneously, increase pressure, fixed press band iron 6, prevent the water in pipeline from flowing out, confirm that tube wall is anhydrous to ooze out, band iron 6 is closely welded with steel pipe walls surrounding, welding completes, confirm firmly, observing certain hour reaffirms without infiltration phenomenon, then Unscrew 4, remove channel-section steel 1.
A kind of device for steel pipe welding with pressure of the present utility model is provided with channel-section steel 1, steel pipe tube wall is welded to by channel-section steel 1, by tightening screw rod 4, pressure is forced on band iron 6 that Lou eye, trachoma and weld seam fine fisssure tube wall are placed, prevent flowing water pressure in pipeline from acting on Lou eye, trachoma and weld seam fine fisssure place, flowing water affects weld job, and stops pipeline leakage eye, trachoma and weld seam fine fisssure place to leak by impressed pressure, can complete weld job smoothly.Welded and confirmed firmly, turned on screw rod 4, it is little the channel-section steel 1 of spot welding to be removed the impact caused pipeline.Without the need to draining of cutting off the water, decrease operation sequence, on water supply and sewage without impact, shorten Lou eye, trachoma and weld seam fine fisssure processing time greatly, improve operating efficiency, solve and can not to cut off the water draining and complete the problem of Lou eye, trachoma and the process of weld seam fine fisssure again under objective condition restriction.
