Abstract

The invention discloses an anti-freezing valve of a tap-water pipe, and belongs to the technical field of anti-freezing of water intaking, water collecting and water distribution. The anti-freezing valve can be used for solving the problem that a tap-water pipe and a tap-water valve are frozen at a low temperature in winter. The anti-freezing valve comprises a valve body, a pump body, a water discharging pipe, an outer sleeve, an elbow, a handle stud gate, a valve, a water plugging valve and a handle, wherein the handle is connected with the elbow through a connecting pipe; the handle stud gate is connected with the top of the outer sleeve through threads; the elbow is connected with the water discharging pipe through threads; the pump body controls the switch of water through the water plugging valve; the handle swirls the handle on the upper part of the water discharging pipe clockwise, the valve is pushed downward by the water discharging pipe at the interior of the outer sleeve, namely the valve is pushed along with the water discharging pipe, the water plugging valve is pushed downward, and water enters from a water pipe at the middle of the valve body to the elbow, thus the water can be used; and the handle on the upper part of the elbow is swirled anticlockwise, the handle is pushed upward, the valve is also pushed upward, the water inlet is sealed by the water plugging valve, and the stored water in the water discharging pipe is drawn into the pump body, thus the water discharging pipe is empty, the tap-water pipe can be effectively prevented from being frozen and blocked, and the tap-water pipe can be prevented from cracking caused by freezing in the cold winter. The anti-freezing valve has the advantages of simple structure and low manufacturing cost, is simple and convenient to install, is convenient to use, has a good anti-freezing effect, and is manufactured for villages and each family of town people to use, and especially for villagers to use.

Description

The tap-water pipe defrosting valve

One, technical field the invention belongs to water intaking, catchments or the freezing proof technique field of water distribution, particularly relates to a kind of tap water anti-freezing control valve unit.

Two, background technique is at the vast northern area of China, after entering winter, temperature all can descend at any time suddenly, lowest temperature has dropped to 0 ℃ once, under applying working condition not, velocity of medium is zero in the feedwater piping, behind the logical tap water in village village, because most of depotition cock is all in institute of peasant household, by the time winter, passive icing not water outlet of water pipe is in order to guarantee water supply pipe normal operation in the winter time, avoid the freezing water pipe from freezing crack that is far more than of tap water to influence life, produce, must carry out antifreeze processing to water supply pipe, perhaps scald with hot water, perhaps roasting with naked light, perhaps use cotton, linen or PE insulating rubber plastic closely twine exposed water pipe and the first-class water facility of the fire hose, wrapping is also fixed with tape, but under cryogenic conditions in the pipe stop water still can ice clean.

Three, a kind of tap-water pipe defrosting valve is provided during the novel purpose of this use of summary of the invention, solved running water pipe under the winter low temperature condition, the problem that valve freezes, it comprises valve body, the pump housing and handle, the handle valve rod interior with placing valve body is connected, valve rod is connected with the valve body top by screw thread, be provided with nut at the valve body top, it comprises valve body, the pump housing, outlet pipe, outer sleeve, elbow, handle Luo Men, valve, water blocking valve used and handle, handle is connected with elbow by connecting tube, handle Luo Men is connected with the outer sleeve top by screw thread, elbow is connected with outlet pipe by screw thread, outlet pipe in the outer sleeve is connected with valve by screw thread, valve body lower end has water intake, elbow setting and water outlet, and the pump housing is by the switch of water blocking valve used control water, the handle on the clockwise turn outlet pipe of handle top, to promote valve to the outlet pipe of outer sleeve inside downwards also just along with outlet pipe promotes downwards, water blocking valve used downward promotion, water will just can be drunk water to elbow from the water service pipe at valve body middle part.The handle on counterclockwise turn elbow top, handle will upwards promote, and valve also can upwards promote, water blocking valve usedly will seal water intake, the water in the outlet pipe is sucked in the pump housing, make it to become blank pipe, just can prevent effectively that running water pipe from freezing betting contest, avoid at bursting by freezing in the winter of cold water pipe, the present invention is simple in structure, and fabricating cost is low, install simple, easy to use, good freezing protection effect, make in the rural area, cities and towns unshared housing especially peasant household use.

Four, description of drawings Fig. 1 is a structural representation of the present invention;

Five, embodiment is frozen valve below in conjunction with Fig. 1 to the anti-handle Luo Men of running water pipe of the present invention and is further described, it comprises valve body 4, the pump housing 1 and handle 3, handle 3 is connected with elbow 6 by connecting tube 8,10 are connected with outer sleeve 2 tops by screw thread, elbow 6 is connected with outlet pipe 9 by screw thread, outlet pipe 9 in the outer sleeve 2 is connected with valve 4 by screw thread, there is the water flowing mouth of pipe 11 valve body 4 lower ends, the pump housing 5 is by the switch of water blocking valve used 7 control water, elbow sets out the water intake 12 of the mouth of a river 13 and pump housing lower end, water intake 12 is connected with running water pipe, water outlet 13 is connected with outlet pipe, then that the pump housing 5 is buried below frozen soil layer, the handle 1 on handle 3 clockwise turn outlet pipes 9 tops, to promote valve 4 to the outlet pipe 9 of outer sleeve 2 inside downwards also just along with outlet pipe 9 promotes downwards, promote water blocking valve used 7 downwards, water will be from the water service pipe 11 in the middle part of the valve body to elbow 6, just can drink water, the handle 3 on counterclockwise turn elbow 6 tops, handle 3 will upwards promote, and valve 4 also can upwards promote, and water blocking valve used 7 will seal water intake 12, water in the water supply pipe in water in the outlet pipe 9 suction pump housing 5 can not freezed, avoid water pipe from freezing crack.
