Abstract
The utility model relates to a freeze-proof ground pump of a tap water pipe, which belongs to the field of freeze-proof technologies of water taking, water collection or water distribution, and can solve the problem that the tap water pipe and a valve are frozen under the low-temperature condition in winter. The freeze-proof ground pump comprises a valve body, a pump body and a handle, wherein the handle is connected with a plunger rod placed in the valve body through a pin, the plunger rod is connected with the top of the valve body through a thread, oil seals are arranged in the upper position and the lower position of the middle part of the plunger rod at an interval, a water inlet and a water outlet are formed in the upper position and the lower position of the middle part of the valve body at the interval, the valve body and the pump body are connected into a whole, an outer cover is arranged outside the pump body, the outer cover is fixedly connected with the pump body through a collar clamp or the threads at the upper part, the plunger rod and a piston in the pump body are connected into the whole, vent holes are formed at the center of the top of the piston and the shaft center of the plunger rod, one to three O-shaped seal rings are arranged on the piston, and a screw cap is arranged at the top of the valve body. The freeze-proof ground pump of the tap water pipe is characterized by simple structure, low cost, simple installation, convenient use and good freeze-proof effect, and is applicable to outdoor tap water pipes in villages and towns.
Description
Technical field
The utility model belongs to water intaking, catchment or the freezing proof technique field of water distribution, particularly relates to a kind of water supply pipe defroster.
Background technology
Wide geographic area in northern China; after entering winter; temperature is generally all below 0 ℃; under applying working condition not; water flow velocity in the feedwater piping is zero; after the logical tap water in village village; because most of water tap all is placed in the institute of peasant household; running water pipe usually can frozen not water outlet in the winter time; in order to guarantee water supply pipe normal operation in the winter time, avoid the frozen even bursting by freezing of running water pipe, influence is produced; life; must carry out antifreeze processing to water supply pipe; perhaps scald with hot water, perhaps roasting with naked light, perhaps exposed water supply pipe and the first-class water facility of the fire hose are wrapped up winding with ramie cotton fabric or PE insulating rubber plastic; and fix with tape, but the stop water in the water supply pipe still can freeze and not water outlet under cryogenic conditions.
Summary of the invention
The purpose of this utility model provides a kind of tap-water pipe defrosting ground pump, 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 plunger rod interior with placing valve body is connected by pin, plunger rod is connected with the valve body top by screw thread, be arranged at intervals with oil sealing up and down at the plunger rod middle part, oil sealing is made up of 1～3 O RunddichtringO, be arranged at intervals with up and down at the valve body middle part, delivery port, the valve body and the pump housing are connected as a single entity, be outside equipped with outer cover at the pump housing, outer cover is fixedlyed connected with the pump housing by the clip or the screw thread on its top, piston in the plunger rod and the pump housing is connected as a single entity, and top land just in and the plunger lever shaft heart be provided with air vent, depth pistion is half of pump housing height, and it is identical with spacing distance between the oil sealing, piston is provided with 1～3 O RunddichtringO, be provided with nut at the valve body top, handle turns clockwise, close the water supply pipe water inlet, the pull plunger rod also drives piston, and the stop water in the water supply pipe is sucked in the pump housing, makes it to become blank pipe, just can prevent effectively that water supply pipe from freezing to stop up, avoid having simple in structure, with low cost at bursting by freezing in the winter of cold running water pipe, simple installation, easy to use, the characteristics of good freezing protection effect are applicable to the rural area, the outdoor tap water pipe in cities and towns.
