Abstract
The utility model discloses an antifreeze emptying valve, which mainly comprises a valve body 1, a screw thread bonnet 11 and a covering cap 16. The utility model is characterized in that a hollow bracket 15, a water stop block 5, a valve core bracket 17 are arranged in a valve closure 1, wherein, a pressure diaphragm pad 12 is arranged between the valve core bracket 17 and the covering cap 16; a pressure switch 14 of which a pressure plate 13 is arranged in the one end, is arranged in the one end of the diaphragm 2, on which and at one end of the water stop block 5 a water stop pad 4 is arranged. And a spring 3 is arranged between the water stop 4 and the hollow bracket 15. Under the circumstance that the amount of the water in the solar energy water tank keeps steady, that piping out all the water from the upper water pipe and the lower water pipe trough the above devices can avoid the pipeline freezing caused by the low temperature. Therefore, the antifreeze emptying valve can be extensively used in the fields of installation and application for the solar energy water heater.
Description
Technical field
The utility model relates to a kind of antifreeze exhaust-valve that is used for the solar water heater field.
Background technique
Solar water heater as zero of a kind of cleaning pollute, the domestic hot water center of zero energy consumption, slowly entered huge numbers of families, bring great convenience to daily life, by people are known together.But in use often, the big temperature difference of local climate freezes stifled fracture phenomena because causing, serious waste water resources, make roof and excess surface water Cheng Bing, caused corresponding potential safety hazard, must overhaul to change every year and damage parts, influence the practicability of the solar energy whole year, increased the expense in the using process.Above problem, solution one commonly used is the thickness (easy-weathering comes off) that increases the pipeline heat insulation material of solar energy, the 2nd, increase and use the ribbon heater (to be prone to wire short-circuiting, catch fire), electronic exhaust-valve (cost height, fragile) is installed besides, all can not be reached desirable practical effect fully.
Summary of the invention
The purpose of this utility model is that a kind of antifreeze exhaust-valve is provided, and cost is low, easy for installation, practical, can effectively avoid solar pipe to freeze stifled fracture phenomena.Its working principle is under the constant situation of the water yield in keeping solar water container, the water emptying in water inlet and the sewer, thereby avoided freezing, and when using, can reach valve next time once opening the using effect that hot water flows down because of the pipeline that low temperature causes.
For reaching above effect, the utility model mainly is made up of valve body 1, screw cap 11, block 16, valve body 1 is connected by screw cap 11 with block 16, in valve gap 1, be provided with stifled 5, the spool support 17 of hollow out support 15, sealing, be provided with pressure diaphragm pad 12 between 16 with blocking a shot at spool support 17; One end of valve shaft 2 is provided with pressure switch 14, and an end of pressure switch 14 is provided with pressure plate 13, on valve shaft 2, an end of sealing stifled 5 also is provided with waterstop pad 4, is provided with spring 3 between waterstop pad 4 and the hollow out support 15.On valve body 1, also be provided with return-air valve 6, in return-air valve 6, be provided with return-air pad 7.
By above setting, the utility model can effectively avoid solar pipe to freeze stifled fracture phenomena, and is easy for installation, practical.

Embodiment
As shown in Figure 1 and Figure 2, the utility model mainly is made up of valve body 1, screw cap 11, block 16, valve body 1 is connected by screw cap 11 with block 16, on valve body 1, be provided with water pipe adapter A, B, on block 16, be provided with water pipe adapter C, also be provided with return-air valve 6 on the valve body 1, in return-air valve 6, be provided with return-air pad 7, be used in valve body 1, replenishing air in following water process.In valve gap 1, be provided with stifled 5, the spool support 17 of hollow out support 15, sealing, sealing stifled 5 and spool support 17 are equipped with sealing gasket (8,10) with valve body 1 joint, to play seal action, between spool support 17 and block 16, be provided with pressure diaphragm pad 12, pressure diaphragm pad 12 is a pad, be subjected to ambient pressure and just can uphold distortion, be used for pilot pressure switch 14.One end of valve shaft 2 is provided with pressure switch 14, one end of pressure switch 14 is provided with pressure plate 13, on valve shaft 2, an end of sealing stifled 5 also is provided with waterstop pad 4, be provided with spring 3 between waterstop pad 4 and the hollow out support 15, when pressure diaphragm pad 12 is subjected to ambient pressure, just can promote pressure plate 13 and drive pressure switch 14 work, when pressure switch 14 is opened, waterstop pad 4 just can separate with sealing stifled 5, whole valve body 1 flowing water is unobstructed, when pressure switch 14 was closed, waterstop pad 4 sealed whole valve body 1 cutted-out by running with sealing stifled 5 under the effect of spring 3.
Now specifying the utility model in conjunction with Fig. 3 installs and working procedure: 1, install: existing solar water heater, generally be provided with upper and lower conduit g and signal tube f, the utility model just is installed in upper and lower conduit g and solar water heater jointing, water pipe adapter A is connected with solar water heater end intake-outlet e, water pipe adapter B is connected with upper and lower conduit g end, one threeway safety check d is installed on signal tube f, the joint of threeway safety check d is connected with water pipe adapter C, two joints are connected with signal tube f respectively in addition, between running water pipe j and signal tube f, meet a valve (1) i, at following termination one valve (2) k of signal tube f, installation process promptly is above program.2, using process: 1. in summer during without the utility model, with pressure switch 14 states of being made as out, throttle down (1) i opens valve (2) k, uses solar water heater by original programmed sequence of operations.Now the control procedure of pressure switch 14 is done an explanation, when pressure switch 14 was opened by the pass change, throttle down (2) k opened valve (1) i5 about second, and the current among the signal tube f promote pressure diaphragm pad 12 pressure switch 14 is become out state; Pressure switch 14 by opening when become closing, is similarly above operation.2. in freezing season, during last water, transfer out pressure switch 14 to state, after having gone up water, transfer pressure switch 14 to off status, then the water emptying among the upper and lower conduit g is got final product, play antifreeze purpose, when using solar water heater, transfer out pressure switch 14 to state and get final product.
