Abstract

The invention discloses a tap water pipe negative pressure antifreezing ground pump, belonging to the technical field of antifreezing in water utilizing, water collecting and water distributing, and solving the problem that tap water pipes and valves are frozen at low temperature in winter. The ground pump comprises a pump body, a valve body, a handle and a water outlet pipe, a handle iron bar in a handle pipe is connected with a pump body screw rod by a screw, a handle outer sleeve is connected with the pump body by a concentric reducer, and the water outlet pipe is directly connected with the pump body by an elbow and an inner screw. The pump body is internally provided with the valve body, the lower end of the pump body is arranged at a water inlet, a water blocking valve is arranged at the middle part of the water inlet, the pump body controls the on and off of water through the water blocking valve; the handle at the upper part of the handle pipe is rotated clockwise, the handle iron bar in the handle tube is pushed downward through the screw rod and a valve is also pushed downward along with the handle iron bar, and the water blocking valve is also pushed downward, and then water flows to the water outlet pipe from a water pipe at the side of the pump body and water can be used conveniently. The handle at the upper part of the handle pipe is rotated anticlockwise, the handle is pushed upward, the valve is also pushed upward, and the water blocking valve can block the water inlet to suck the water stored in the water outlet pipe into the pump body, thus the water outlet pipe is empty, the tap water pipe can be effectively prevented from being frozen and blocked, and the water pipe does not burst in cold winter. The ground pump is easy to install and convenient to use, has the advantages of simple structure, low manufacturing cost and good antifreezing effect and is applicable to families in urban and rural areas, especially suitable for rural families.

Description

The running water pipe negative pressure is prevented the frozen ground pump

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 valve gear.

Two, background technology 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, provide a kind of tap-water pipe defrosting valve during summary of the invention purpose of the present invention, solved the problem of running water pipe, anti-freeze under the winter low temperature condition, it comprises that the pump housing, valve body and handle comprise that the handle iron rod in valve body, the pump housing, outlet pipe, the handle tube is connected and pump housing screw rod by screw, the handle outer tube connects and the pump housing by concentric reducer, and outlet pipe directly connects and the pump housing by elbow, internal thread.Be provided with valve body in the pump, water inlet is located in pump housing lower end, the water inlet middle part is provided with water blocking valve used, the pump housing is by the switch of water blocking valve used control water, the handle on clockwise turn handle tube top, to promote valve to the handle iron rod of handle tube inside also just along with the handle iron rod promotes downwards by screw rod, water blocking valve used downward promotion, water will just can be drunk water to outlet pipe from the water service pipe of pump housing side.The handle on counterclockwise turn handle tube top, handle will upwards promote, and valve also can upwards promote, water blocking valve usedly will seal water inlet, the water in the outlet pipe is sucked in the pump housing, making it outlet pipe becomes 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 cost of manufacture 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 this practical invention structural representation;

Five, the specific embodiment is frozen valve below in conjunction with Fig. 1 to the anti-handle Luo Men of this practical invention running water pipe and is further described, it comprises valve body 5, the pump housing 1 and handle 8, handle 8 is connected with iron rod 3 by screw, iron rod 3 bottoms connect and screw rod 9 by screw, there is outlet pipe 6 delivery port 4 upper ends, pump housing side, the pump housing 12 is by the switch of water blocking valve used 7 control water, water inlet 10 is connected with running water pipe, delivery port pipe 6 is connected with outer silk direct 4, then that the pump housing 12 is buried below frozen soil layer, the handle 8 on clockwise turn handle tube 2 tops, to promote valve 5 to the handle iron rod 3 of handle tube 2 inside also just along with handle iron rod 3 promotes downwards by screw rod 9, promote water blocking valve used 7 downwards, water will just can be drunk water to outlet pipe 6 from the water service pipe 4 of the pump housing 12 sides.The handle 8 on counterclockwise turn handle tube 2 tops, handle 8 will upwards promote, and valve 5 also can upwards promote, and water blocking valve used 7 will seal water inlet 10, the water that 6 water in the outlet pipe is sucked in the water supply pipe in the pump housing 12 can not freeze, and avoids water pipe from freezing crack.
