Description

Emptying type unfreezable tap

Technical field

The utility model relates to unfreezable tap, specifically a kind of emptying type unfreezable tap.

Background technique

Because grange belongs to self-built housing mostly, ununified supporting tap water facility within doors.Therefore, adopt the village water supply line of tap water supply can only be routed in institute of peasant household, this is for northern country, and for antifreeze, water supply line can be embedded in below underground frost retarding layer, but more than the water bolt of outlet terminal can only be arranged on frost retarding layer.Common water bolt can be stayed in water bolt standpipe crossing remaining water after water, and the water freezing in standpipe makes the water bolt can not water outlet, cannot use.For this problem, CN201992120U discloses a kind of buried antifreezing tap, although can solve the antifreeze problem of water bolt, but the valve body structure of this unfreezable tap and Shui Shuan open and close controlling mechanism existing problems: the one, adopt ring-type to stop up the osculum on shutoff valve body, stop up the friction of outer rim and valve body annular inner wall, be easy to make stop up tightly shutoff osculum, while causing water, water is flowed out outside water bolt by osculum, waste tap water, and affect pressure of supply water, stop up working life; Two Shi Shuishuan open and close controlling mechanism complex structures, manipulation inconvenience.

Model utility content

The utility model is intended to solve the problem that above-mentioned unfreezable tap exists, and provide, a kind of valve body structure design is more reasonable, the emptying type unfreezable tap of long service life.

The technological scheme that the utility model solves its technical problem employing is:

A kind of emptying type unfreezable tap, comprise valve body, the spool that blocks water, emptying spool, standpipe, water outlet and Shui Shuan open and close controlling mechanism, in the middle of valve body, endoporus is made up of the normal cone hole of Lower Half and the rounding taper hole of the first half, the spool that blocks water is the normal cone body mating with described normal cone hole, and emptying spool is the inverted cone mating with described rounding taper hole; The arc that is arranged at intervals with upper and lower perforation on the madial wall of endoporus in the middle of described valve body is crossed water groove, and the spool that blocks water can block described arc while rising crosses the lower end mouth of water groove; On the valve body of corresponding described inverted cone hole site, have the weep hole of lateral direction penetrating, emptying spool can block described weep hole while decline.

The utility model that adopts technique scheme, compared with prior art, its beneficial effect is:

In in the middle of valve body, bore portion coordinates with block water spool and emptying spool employing cone structure, solved emptying spool because of with the tightly problem of shutoff weep hole of valve interior wall friction, extended thus working life of unfreezable tap.

As preferably, the utility model further technological scheme is:

Described Shui Shuan open and close controlling mechanism comprises Joystick, lifting bar, lifting bar runs through the standpipe of water outlet and lower end connection thereof, lifting bar lower end fixes as one with the spool that blocks water, emptying spool, lifting bar upper end is connected with Joystick, water outlet upper end open portion is equipped with sealing gland, is equipped with the sealed plunger coordinating with described sealing gland on lifting bar.

Its specialization of above-mentioned Shui Shuan open and close controlling mechanism is: in the time that Joystick drives lifting bar to rise or declines, only between lifting bar and sealing gland, produce elastic-friction, lifting bar is not had to frictionally damage, and sealing gland is changed also very convenient, and cost is very low; On water bolt, when water, sealed plunger coordinates with sealing gland, better to the sealing effect of water outlet upper end open portion, meanwhile, the frictional force between lifting bar and sealing gland, can overcome the buoyancy of tap water to the spool that blocks water, make lifting bar location, water state in maintenance.Such Shui Shuan open and close controlling mechanism, simple in structure, manipulation is flexible.

Fig. 2 is A-A sectional view in Fig. 1;

In figure: 1-Joystick, 2-sealed plunger, 3-sealing gland, 4-water outlet, 5-standpipe, 6-lifting bar, 7-weep hole, 8-valve body, 9-tap water main pipeline, 10-water-inlet cavity, the 11-spool that blocks water, 12-arc is crossed water groove, the emptying spool of 13-, 14-water chamber.

Embodiment

Below in conjunction with embodiment, the utility model is described in further detail, and object is only better to understand the utility model content.

Referring to Fig. 1, Fig. 2, the emptying type unfreezable tap that the present embodiment provides, the middle endoporus of its valve body 1 is made up of the normal cone hole of Lower Half and the rounding taper hole of the first half, the spool 11 that blocks water is normal cone bodies, mate with the normal cone bore portion of middle endoporus, emptying spool 13 is inverted cones, mates with the inverted cone bore portion of middle endoporus; The arc that is arranged at intervals with three upper and lower perforations on the madial wall of middle endoporus is crossed water groove 12, and the spool 11 that blocks water can block arc while rising crosses the lower end mouth of water groove 12; On the valve body 1 of inverted cone hole site, have the weep hole 7 of lateral direction penetrating, emptying spool 13 can block weep hole 7 while decline.

The water-inlet cavity 10 of valve body 1 lower end is connected with tap water main pipeline 9, and the water chamber 14 of valve body 1 upper end is connected with standpipe 5 lower ends, and standpipe 5 upper ends connect water outlet 4.

Shui Shuan open and close controlling mechanism is made up of Joystick 1, sealed plunger 2, sealing gland 3, lifting bar 6, lifting bar 6 runs through water outlet 4 and standpipe 5 successively, lifting bar 6 lower ends fix as one with the spool 11 that blocks water, emptying spool 12, lifting bar 6 upper ends are connected with Joystick 1, water outlet 4 upper end open portions are equipped with sealing gland 3, are equipped with the sealed plunger 2 coordinating with sealing gland 3 on lifting bar 6.

Press down Joystick 1, lifting bar 6 moves down, and the spool 11 that blocks water blocks weep hole 7, the lower end mouth that emptying spool 13 is crossed water groove 12 with arc separates, meanwhile, the water in water-inlet cavity 10 is crossed water groove 12, standpipe 5, water outlet 4 by arc successively and is discharged, and realizes and supplying water.

On carry Joystick 1, on lifting bar 6, move, the spool 11 that blocks water separates with weep hole 7, emptying spool 13 blocks arc crosses the lower end mouth of water groove 12, stops upper water; Meanwhile, standpipe 5 is discharged outside water bolt by weep hole 7 with the ponding in water chamber 14, realizes emptying.

When this emptying type unfreezable tap is installed, valve body 1 and standpipe 5 Lower Halves are generally embedded in underground, and weep hole 7 is answered landfill grit or rock ballast around, is beneficial to standpipe 5 emptying with the ponding in water chamber 14.
