Description
Technical field
The utility model is mainly concerned with the protector field in the tap water supply device, refers in particular to a kind of defroster of running water pipe.
Background technology
The antifreeze problem of running water pipe is puzzlement northerner's a major issue always, directly affect people's life or industrial water, particularly northerly Timing water supply area, the air pressure of after cutting off the water because running water pipe inside is low, so can leave one section water column all the time in running water pipe, this is to cause the basic reason of freezing in the running water pipe in winter.For this reason, people have taked multiple preventive means, and are regional such as the major part at northern country, and outdoor running water pipe just carries out antifreeze with straw or winding one deck cotton-wool, but still can not reach antifreezing effect fully, and influences attractive in appearance.At present, there is the practitioner to develop various defrosters, but these defrosters that had, structure is very complicated, and it is also comparatively complicated to operate, and needs certain engineering quantity during installation again, extremely inconvenient, so do not promoted on a large scale.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem of prior art existence, the utility model provide a kind of simple in structure, with low cost, do not need artificial control, the defroster of the running water pipe that antifreezing effect is better, applied widely.
In order to solve the problems of the technologies described above, the solution that the utility model proposes is: a kind of defroster of running water pipe, it is characterized in that: it comprises piston cylinder, piston rod and linkage, piston cylinder is positioned at the top of running water pipe and is communicated with running water pipe, the top of piston cylinder offers air inlet, and the position of piston cylinder is higher than the position of the water tap of running water pipe; Piston rod is inserted in the piston cylinder, and an end of piston rod links to each other with the linkage on being fixed in piston cylinder, and the other end of piston rod is provided with a female piston sheet, and the concave surface of piston sheet down.
Described connecting rod is an arc, and the one end is articulated on the fixed bar, and another section is affixed with piston rod; Connecting rod rotates around pin joint, and its distance of moving in vertical direction is less than the height of piston cylinder inner chamber.
Described piston sheet is anchored on the piston rod by Upper gasket and top nut and lower gasket and lower nut.
Described piston cylinder links to each other with water tap with running water pipe by threeway.
Compared with prior art, advantage of the present utility model just is: the defroster of the utility model running water pipe is simple in structure, with low cost, it is convenient to install and clean, do not need artificial control, and antifreezing effect is better, applied widely.

The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, the defroster of running water pipe of the present utility model, it comprises piston cylinder 1, piston rod 2 and linkage, piston cylinder 1 is positioned at the top of running water pipe 5 and is communicated with running water pipe 5, the position of piston cylinder 1 should be higher than the position of the water tap 11 of this running water pipe 5, in preferred embodiment, can two logically change threeway 13 into what connect running water pipe 5 and water tap 11, piston cylinder 1, running water pipe 5 and water tap 11 are connected by threeway 13 get final product.The top of piston cylinder 1 offers air inlet 12.Piston rod 2 is inserted in the piston cylinder 1, one end of piston rod 2 links to each other with linkage on being fixed in piston cylinder 1, the other end of piston rod 2 is provided with a female piston sheet 6, this piston sheet 6 can adopt rubber stopper, the concave surface of piston sheet 6 and is anchored on the piston rod 2 by Upper gasket 7 and top nut 9 and lower gasket 8 and lower nut 10 down.Linkage comprises connecting rod 3 and fixed bar 4, and fixed bar 4 is fixed on the piston cylinder 1.Connecting rod 3 is an arc, and the one end is articulated on the fixed bar 4, and another section is affixed with piston rod 2, and connecting rod 3 rotates around pin joint, and its distance of moving in vertical direction is less than the height of piston cylinder 1 inner chamber.
Operating principle: as shown in Figure 1, when normal water supply state, the pressure of tap water is bigger, therefore be full of tap water in running water pipe 5, water tap 11 and the piston cylinder 1, piston rod 2, piston sheet 6 promote linkage and are in highest position in the lump, female piston sheet 6 below under the effect of big hydraulic pressure, will be closely attached on piston cylinder 1 inwall more, play good sealing effectiveness.As shown in Figure 2, fasten water tap 11 after using up water, to after the time that stops to supply water, the liquid level of tap water can fall back to below the height and position of water tap 11 in the running water pipe 5, anhydrous in the piston cylinder 1, but icing at low temperatures life-span and normally the taking of tap water to running water pipe 5 of the Yu Shuihui in the running water pipe 5 impacts.In the process that tap water falls after rise, tap water in the piston cylinder 1 can and then fall equally, piston rod 2, piston sheet 6 together moves down, connecting rod 3 rotates around the pin joint on the fixed bar 4, when moving to certain position, in linkage under the restriction of connecting rod 3, tap water continues to fall after rise and piston rod 2, piston sheet 6 will can not fall again, at this moment, to form negative pressure cavity between tap water liquid level and the piston sheet 6, air pressure in this negative pressure cavity will be less than atmospheric pressure, utilize the particular design of female piston sheet 6, atmospheric pressure will enter in the negative pressure cavity from the air inlet 12 on piston cylinder 1 top and the side of female piston sheet 6, forces the liquid level of the tap water in the running water pipe 5 to continue to descend; Because liquid level constantly reduces, therefore the volume of negative pressure intracavity gas constantly increases, air pressure constantly reduces, when less than atmospheric pressure, atmosphere will continue to enter in the negative pressure cavity from the side of the air inlet 12 on piston cylinder 1 top and female piston sheet 6, force the liquid level of the tap water in the running water pipe 5 to continue to descend; And the like, the whole emptyings of remaining tap water (referring to Fig. 3) in running water pipe 5 so just can effectively avoid running water pipe to be frozen in.After water supply recovers, tap water can be filled with running water pipe 5 and piston cylinder 1 rapidly under the control of hydraulic pressure, be full of tap water in the piston cylinder 1, piston rod 2, piston sheet 6 promote linkage and are in highest position in the lump, and this moment, the user just was in the water supply state as can be seen from the turned position of linkage.
