Abstract
The utility model relates to an anti-freezing device for running water pipe, comprising a valve body, a drainage pipe, a handle, a valve core, a water inlet, a lining, etc. The utility model combines a water pipe tap and an anti-freezing device into integration; when used, the handle is rotated towards left, an operating lever is moved up, the valve core is disengaged from the surface of the lining, and the water flows out of the water tap through the lining; the handle is rotated towards right, the operating lever is moved down, the water source is cut off, meanwhile, the lining is forced to move down to a drainage port and expose out, and the water of the water pipe is lifted from the drainage port, which causes the running water pipe to achieve the anti-freezing purpose.
Description
The utility model relates to a kind of tap-water pipe defrosting device.
At present, the running water pipe of urban and rural residents open air because winter temperature is low, makes water in the water pipe freeze easily or water pipe from freezing crack, influences the normal water of resident, has brought a lot of troubles to numerous residents.
The utility model is to provide a kind of tap-water pipe defrosting device for solving above-mentioned deficiency, and it just can make water pipe not freeze winter without any need for the insulation measure.The utility model cost is low, easy to use, is specially adapted to the preventing freeze in winter of the running water pipe of urban and rural residents open air.
The utility model is to realize like this, the valve body upper end connects outlet pipe, one action bars that is connected with handle is arranged in the outlet pipe, there is a guide pin bushing action bars lower end, and the centre bore in the guide pin bushing matches with the valve rod of spool, and there is an annular boss at the valve interior wall middle part, a lining is equipped with in the boss below, the lining periphery is with sealing ring, and spring is housed in the lining, also is provided with a sluicing through hole on valve body wall.During use, rotary handle left, action bars is upwards mentioned, simultaneously spool also under the pressure of water with on move, and break away from the lining upper surface.Lining also moves being forced under the elastic force effect, and when the valve body annular boss was withstood in the lining upper end, discharge opening was plugged, and at this moment, water flows out from faucet from bottom to top through lining.Rotary handle to the right, action bars promote spool and move down, and when the rubber pad on the spool was pressed in the lining upper surface, the water source was cut off, and continued rotary handle again, and lining continues to move down, till the discharge opening on the valve body wall exposes.At this moment, the water in the water pipe of top is discharged through discharge opening, thereby has reached the purpose of tap-water pipe defrosting.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sectional view of the utility model tap-water pipe defrosting device.
Fig. 2 is the A-A sectional drawing of the utility model valve body.
With reference to accompanying drawing, the outwards outstanding cavity 23 of one symmetry is arranged at valve body of the present utility model 12 tops, and valve body 12 upper ends connect outlet pipe 5, outlet pipe 5 upper ends connect swivel nut 4 and faucet 22, and encapsulant 3 is housed in the swivel nut 4, and action bars 2 is positioned at the center of swivel nut 4 and outlet pipe 5, there is one handle 1 upper end of action bars 2, there is a guide pin bushing 6 lower end, and the centre bore 7 in the guide pin bushing 6 matches with the valve rod 9 of spool 8, and spool 8 is made up of valve rod 9, platen 10, rubber pad 11.There is an annular boss 13 at valve body 12 inwalls middle part, and boss 13 internal diameters are greater than the external diameter of platen 10 and rubber pad 11.Below boss 13, one lining 14 is arranged, lining 14 is a hollow circular cylinder, its external diameter is greater than the internal diameter of boss 13, and lining 14 outer walls match with valve body 12 inwalls, one annular boss 15 is also arranged on the inwall of lining 14 upper ends, these boss 15 internal diameters are less than the external diameter of platen 10 and rubber pad 11, spring 18 is housed in the lining 14, lining 14 peripheries have cannelure 17, and sealing ring 16 is housed in the cannelure 17, in order to sealing, anti-sealing leaks, and on valve body 12 walls that lining 14 outer walls match a sluicing through hole 21 is arranged.In addition, the sealing ring 16 on lining 14 tops also can be installed in the soffit of the annular boss 13 of valve body 12, can not slot in lining 14 peripheries, the cannelure 17 of putting sealing ring 16 can be opened on the inwall of the valve body 12 below valve body 12 annular boss 13.One spring 18 is housed in the lining 14, and spring 18 upper ends withstand on the soffit of annular boss 15 in the lining 14, and the lower end is fixed with a screw 19 with holes.Water inlet 20 is positioned at the valve body bottom.
