Abstract
Disclosed is an anti-freezing valve for tap water pipe, comprising a three-way pipe and a protecting pipe. A trampling core is fixedly connected with the upper part of the protecting pipe and a valve cover is connected with the lower part of the protecting pipe; the valve cover is connected with the thread of the three-way pipe. A valve rod is arranged inside the protecting pipe; a spring is nested on the head part of the valve rod, and a valve core is connected with the tail part of the valve rod; a water inlet hole and a water outlet hole are arranged at the lower part of the valve core; a water reversing hole and a water returning hole are arranged at the upper part of the valve core; a trampling cover which is arranged with a pressing handle is connected with the trampling core. The utility model has simple, practical structure and low manufacturing cost. Since the utility model is connected with the three-way pipe, redundant water in a pipe can flow spontaneously out of the water returning hole of the three-way pipe when water discharging is needed for anti freezing to ensure that no water exist inside the pipe. The utility model has good anti-freezing effect and is in particular applicable to outdoor tap water pipes.
Description
Technical field
The utility model relates to a kind of frost valve, particularly a kind of tap-water pipe defrosting valve.
Background technique
Outdoor use tap-water pipe defrosting valve mainly is the automatic deflation type at present, and it is adapted to rural area non-tower water supply system, and when stopping to supply water, because of pipeline pressure reduces, ambient air enters pipeline by certain device, water level is reduced to below the frozen soil layer, to achieve the goal.Its deficiency is, this series products often because of the ducted water droplet of means of deflation, water smoke freeze lost efficacy.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can solve effectively winter outdoor water supply pipe freeze can not water outlet even bursting by freezing problem, the antifreeze valve body that will have threeway is installed in below the frozen soil layer, current are opened, are closed in push-and-pull by valve rod, to reach the tap-water pipe defrosting valve of antifreeze purpose.
The purpose of this utility model is achieved in that it comprises three-way pipe; protective tube, the upper end of protective tube are fixedly connected with steps on core, and the lower end is connected with valve gap; valve gap is threaded with three-way pipe; its structure outline is, valve rod is placed in the protective tube, and its head is with spring; afterbody is connected with spool; the bottom of spool is provided with osculum, water inlet, and top is provided with the hole of turning one's coat, backwater hole, is provided with stepping on lid and stepping on core clamping mutually of pressure handle.
Osculum on the described spool and water inlet are positioned on the same axis, communicate with the outlet and inlet of three-way pipe, and the hole of turning one's coat is positioned on the longitudinal axis with osculum and communicates with backwater hole.
The described outside of stepping on core is provided with feather key, and the inside of stepping on lid is provided with and steps on the featherway that the core feather key cooperates, and steps on core and steps on lid and be connected by feather key, featherway.
One circular hole is arranged at the described top of stepping on lid, and screw therefrom passes with threaded stem and is connected.
Compared with prior art, the utility model is simple and practical, and fabricating cost is cheap.Because it is connected with three-way pipe, when needing antifreeze discharging water in the pipe unnecessary water can flow out naturally from the backwater hole of three-way pipe, guarantee in the pipe anhydrously, good freezing protection effect is specially adapted to outdoor running water pipe use.Spool of the present utility model, valve gap, three-way pipe all adopt engineering plastics or abrasive rubber material be embedded in ground lower seal tightly do not corrode long service life.
The explanation of accompanying drawing drawing
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As accompanying drawing, the utility model is made up of protective tube 14, valve rod 13, three-way pipe 8 etc.Valve rod 13 is placed in the protective tube 14, and the head of valve rod 13 is hollow, the hollow screw thread that is provided with, and the outside of stem head is with spring 2.Step on the head that core 15 is fixedly mounted on valve rod 13, its outside is provided with feather key 16, steps on to cover 4 outside and be provided with pressure handle 3, and there is featherway 17 inside, and featherway 17 cooperates with feather key 16, steps on to cover 4 and be positioned at the outside of stepping on core 15, connects and fixes by feather key 16, featherway 17.Step on the circle centre position that covers 4 tops and open an aperture, screw 1 passes from aperture, with being threaded of valve rod 13 hollow part.The afterbody of valve rod 13 is connected with spool 9, and the bottom of spool 9 is provided with osculum, water inlet, and top is provided with the hole 6 of turning one's coat, backwater hole 7.Osculum and water inlet are positioned on the same axis, communicate with the outlet and inlet 5,10 of three-way pipe, and the hole 6 of turning one's coat communicates with backwater hole 7 on longitudinal axis with osculum.The afterbody that valve gap 12 is fixed on protective tube 14 and three-way pipe 8 be threaded.Be provided with rubber washer 11 in the entery and delivery port 10,5 of three-way pipe 8, rubber washer 11 not only plays sealing process but also can guarantee not to be corroded.
During use, the utility model main body is embedded under the frozen soil layer, step on cover 4 be exposed to outside.The water intake 10 of three-way pipe 8 is connected with the network of rivers from the beginning, and water outlet 5 is connected with service pipe.Accompanying drawing is the embodiment that the utility model supplies water, do not need as accompanying drawing that the outlet and inlet 5,10 of three-way pipe communicates when antifreeze, water flows into the user from water outlet, when need are antifreeze, to pressing down pressure handle 3 springing springs 2, valve rod 13 moves down, and the water inlet on the spool 9 is blocked, and backwater hole 7 backs that unnecessary water flows to from the hole 6 of turning one's coat on the spool 9 in the running water pipe go out from the last orifice flow of three-way pipe 8.Install and to guarantee that normal water supply can guarantee not freezing water pipe again behind the utility model.
