In the such scheme, described upper plier handle 1 and lower pliers head 5 are integrated, and an end is upper plier handle 1, and the other end is lower pliers head 5.
In the such scheme, described lower plier handle 2 and upper grip head 4 are integrated, and an end is lower plier handle 2, and the other end is upper grip head 4.
In the such scheme, described upper grip head 4 and lower pliers head 5 all are circular arc sheet.
In the such scheme, the equal in length of described upper plier handle 1 and lower plier handle 2, and this length is greater than the twice of circular-arc upper grip head 4 and lower pliers head 5 radiuses.
(3) beneficial effect
Can find out from technique scheme, the utlity model has following beneficial effect:
1, the utility model provides is used for compressing when earth-source hot-pump system underground pipe pipe fitting connects and the pipe wrench of sealing, applied widely, simple in structure, easy to use, simultaneously not producing bite mark, do not damage the pipe fitting surface, is the desirable aid that earth-source hot-pump system underground pipe pipe fitting connects.
2, being used for of utilizing that the utility model provides compresses when earth-source hot-pump system underground pipe pipe fitting connects and the pipe wrench of sealing, the Seepage that can avoid the two pipe fittings hot melt to cause in conjunction with the micro gap that may exist, reliability, sealing and bonding strength that hot melt connects have been improved, and processing ease, and operational effect and the service life of earth-source hot-pump system have been guaranteed.
3, being used for of utilizing that the utility model provides compresses when earth-source hot-pump system underground pipe pipe fitting connects and the pipe wrench of sealing, can effectively solve " the molten knurl " that easily produce in the pipe fitting hot melt, reduce water resistance, keep current unimpeded, increase the accuracy of earth source heat pump design.
Description of drawings
Fig. 1 be according to the utility model embodiment be used for compress when earth-source hot-pump system underground pipe pipe fitting connects and the structural representation of the pipe wrench of sealing;
Fig. 2 is the work schematic diagram that utilizes pipe wrench shown in Figure 1 that pipe fitting is compressed and seals when earth-source hot-pump system underground pipe pipe fitting connects according to the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
As shown in Figure 1, Fig. 1 be according to the utility model embodiment be used for compress when earth-source hot-pump system underground pipe pipe fitting connects and the structural representation of the pipe wrench of sealing.This pipe wrench designs based on lever principle, is made of upper plier handle 1, lower plier handle 2, axle 3, upper grip head 4 and lower pliers head 5, and wherein upper plier handle 1, lower plier handle 2, upper grip head 4 and lower pliers head 5 are hinged by axle 3.Upper plier handle 1 and lower pliers head 5 are integrated, and an end is upper plier handle 1, and the other end is lower pliers head 5.Lower plier handle 2 and upper grip head 4 are integrated, and an end is lower plier handle 2, and the other end is upper grip head 4.Upper grip head 4 and lower pliers head 5 all are circular arc sheet.The equal in length of upper plier handle 1 and lower plier handle 2, and this length is greater than the twice of circular-arc upper grip head 4 and lower pliers head 5 radiuses.This pipe wrench is the desirable aid that earth-source hot-pump system underground pipe pipe fitting connects.
As shown in Figure 2, Fig. 2 is the work schematic diagram that utilizes pipe wrench shown in Figure 1 that pipe fitting is compressed and seals when earth-source hot-pump system underground pipe pipe fitting connects according to the utility model embodiment.In underground pipe pipe fitting connection construction, two pipe fittings (being pipe fitting 7 and bellmouth pipe fitting 8) adopts the hot melt spigot-and-socket connected mode, pipe fitting 7 link outer surfaces and bellmouth pipe fitting 8 link inner surfaces are heated to molten condition, the large 2-3mm of the conventional melting bore of bellmouth pipe fitting 8 link inner surface melting relative apertures wherein, this routine melting bore refer to the bore of bellmouth pipe fitting 8 link inner surfaces under molten condition not; Then under the hot melt state, pipe fitting 7 link outer surfaces are inserted bellmouth pipe fitting 8 link inner surfaces, frictional force between the two pipe fittings is minimum at this moment, the generation of " molten knurl " can be farthest avoided in two pipe fittings junction 9, and then the resistance of current in the pipe fitting can be reduced; Then the link with pipe wrench 6 clamping bellmouth pipe fittings 8 also pushes under the hot melt state, make the pipe fitting circumference all be subject to the clamping extruding, with the Seepage of avoiding the two pipe fittings hot melt to cause in conjunction with the micro gap that may exist, last cooling and shaping is finished the connection of two pipe fittings.
In actual applications, pipe wrench 6 is upper grip head 4 and the lower pliers head 5 of circular arc sheet, its radian or radius all can be adjusted according to the diameter of clamping pipe fitting, adapt with the diameter with the clamping pipe fitting, and when using pipe wrench 6, do not need up and down that the embedding head does not mesh at every turn, user that can be by rotation pipe wrench 6 to, make the pipe fitting circumference all be subject to the clamping extruding.
Because this pipe wrench designs based on lever principle, so the length of upper plier handle 1 and lower plier handle 2 generally is greater than the twice of circular-arc upper grip head 4 and lower pliers head 5 radiuses, to reach effect laborsaving and that compress.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
