Abstract

The utility model provides a novel anti-freezing tap-water device and relates to the field of water pipe anti-freezing. The novel anti-freezing tap-water device comprises a cylindrical valve body (1), a piston (2), a sealing ring (5),a water inlet (6), a water outlet (7) and a tap (8), wherein a piston cavity is formed in the cylindrical valve body (1), a movable up and down piston (2) is arranged in the piston cavity. A sealing ring (5) is tightly arranged around the piston (2). The piston (2) is connected with a handle (4) through a piston rod (3) and the handle (4) reveals the ground surface. The half upper end of the piston cavity is connected with a water outlet pipe (7). One end of the water outlet pipe (7) is provided with the tap (8), and the end is revealed above the ground surface. The lower end of the piston cavity is sleeved with a water inlet pipe (6). The novel anti-freezing tap-water device is simple in structure, easy to process and convenient to use. The novel anti-freezing tap-water device can solve the problems that freeze-proof of tap-water pipe is not thorough in the prior art. Water in the cylindrical valve body and the water outlet pipe is extruded into the water inlet pipe through the piston. No water in the piston cavity and water outlet pipe is ensured and the effect of the freeze-proof is achieved.

Description

A kind of Novel anti-freezing water supplying unit

Technical field:

The utility model relates to a kind of water supplying unit, is specifically related to a kind of Novel anti-freezing water supplying unit.

Background technology:

The water supply system outlet valve of at present rural area use is installed in the open air mostly, in northern arctic weather, temperature generally all reaches subzero tens degree, icing season, outdoor flowing water Valve freezed easily in the winter time, must water out with hot water during use, affect user's normal use, bring many inconvenience to the user, at present in order to prevent that this phenomenon from occuring, generally be that part bundlees heat insulating material or assembles a measure such as keeping warmth space with brick more than water pipe ground, these measures not only bother but also not attractive in appearance, and crossing when temperature when low, water pipe below ground part is owing to there is ponding also can freeze, cause water pipe obstructed, existing a kind of defroster is to adopt frost valve at valve lower body place porose seepage flow pipe to be set, behind the valve closing with the water in the valve pipe by hole seepage flow pipe slowly seepage flow go out, this means to prevent freezing is made more complicated, must fall a part of water by seepage flow after being finished at every turn, waste water resource, and the speed of seepage flow is slow, still freeze than the water that is easier to remaining in the valve pipe cold season, can not play thoroughly antifreezing effect.

The utility model content:

The purpose of this utility model provides a kind of Novel anti-freezing water supplying unit, and it can overcome the drawback of prior art, and is simple in structure, and antifreezing effect is obvious.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises cylinder shape valve 1, piston 2, sealing ring 5, water inlet 6, delivery port 7, water tap 8, be plunger shaft in the cylinder shape valve 1, be provided with piston 2 moving up and down in the plunger shaft, closely be provided with sealing ring 5 around the piston 2, piston 2 is connected connection by piston rod 3 with handle, and handle 4 spills ground surface, middle upper end in plunger shaft is connected with outlet pipe 7, an end is provided with water tap 8 more than the ground of outlet pipe 7, is socketed with water inlet pipe 6 in the lower end of plunger shaft.

The utility model is when using tap water, leading 8 switches of fetching boiling water, mention handle 4 and piston 2 is moved to the top of plunger shaft, water will pass through water inlet pipe 6, plunger shaft, outlet pipe 7 flows out from water tap 8, after finishing using, 8 switches turn off the tap, aqueous reflux in the outlet pipe 7 advances plunger shaft, by piston rod 3 piston 2 is moved to simultaneously the bottom of plunger shaft by lower handle 4, because be provided with sealing ring around the piston 2, water in the plunger shaft all can be discharged from water inlet pipe 6, guarantee in the running water pipe anhydrous, thereby reach antifreeze function, prevent from slow infiltrate journey, hanging down with back-flow velocity slow and icing phenomenon that produce because temperature is crossed at the employed common frost valve of extremely frigid zones.

The utility model is simple in structure, be easy to processing, easy to use, can effectively solve the halfway problem of tap-water pipe defrosting in the prior art, by piston the water in cylinder shape valve and the running water outlet pipe is pushed back into water pipe, having guaranteed does not have water in plunger shaft and the outlet pipe, thereby plays antifreeze effect.

Description of drawings:

Fig. 1 is water outlet status architecture schematic diagram of the present utility model;

Fig. 2 is antifreeze status architecture schematic diagram of the present utility model.

The specific embodiment:

Referring to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: it comprises cylinder shape valve 1, piston 2, sealing ring 5, water inlet 6, delivery port 7, water tap 8, be plunger shaft in the cylinder shape valve 1, be provided with piston 2 moving up and down in the plunger shaft, closely be provided with sealing ring 5 around the piston 2, piston 2 is connected connection by piston rod 3 with handle, and handle 4 spills ground surface, middle upper end in plunger shaft is connected with outlet pipe 7, an end is provided with water tap 8 more than the ground of outlet pipe 7, is socketed with water inlet pipe 6 in the lower end of plunger shaft.

This specific embodiment is when using tap water, leading 8 switches of fetching boiling water, mention handle 4 and piston 2 is moved to the top of plunger shaft, water will pass through water inlet pipe 6, plunger shaft, outlet pipe 7 flows out from water tap 8, after finishing using, 8 switches turn off the tap, aqueous reflux in the outlet pipe 7 advances plunger shaft, by piston rod 3 piston 2 is moved to simultaneously the bottom of plunger shaft by lower handle 4, because be provided with sealing ring around the piston 2, water in the plunger shaft all can be discharged from water inlet pipe 6, guarantee in the running water pipe anhydrous, thereby reach antifreeze function, prevent from slow infiltrate journey, hanging down with back-flow velocity slow and icing phenomenon that produce because temperature is crossed at the employed common frost valve of extremely frigid zones.

This specific embodiment is simple in structure, be easy to processing, easy to use, can effectively solve the halfway problem of tap-water pipe defrosting in the prior art, by piston the water in cylinder shape valve and the running water outlet pipe is pushed back into water pipe, having guaranteed does not have water in plunger shaft and the outlet pipe, thereby plays antifreeze effect.
