The two-way air valve of formula.The automatic air-intaking exhaust valve of float-ball type bi-directional configuration realizes the bilateral flow of water storage chamber air.
Referring to Fig. 2, a kind of preferred embodiment as the utility model, the manual needle valve 21 is hand stream
Measure drain valve.Manual structure drain valve facilitates people to the regulation and control of valve.
Referring to Fig. 1, a kind of preferred embodiment as the utility model, the valve rod 1 is connected to outside spring valve
Body of rod end by connect bearing connect with pedal.It is connect by valve rod with pedal, effectively realizes through pedal and control
Make the inflow and outflow of entire frost valve.
A kind of water saving frost valve described in the utility model, ground pedal pressure is stepped on when people are in daily water consumption
Downward power is transmitted to valve rod 1 and pushes the compressed springs such as pintongs spool 8 and water shutoff rubber mat 9 open by bar, and spring valve is opened, and water is in pressure
Four grooves through pintongs spool 8 under effect flow to water-blaster 16 and form firing rate water flow, and firing rate water flow injects 26 center of water outlet device
Hole, high-speed motion of the firing rate water flow in 26 centre bore of water outlet device make to generate negative pressure in threeway 27, the pressure in negative pressure and pipeline,
The firing rate of water flow and the emptying amount of water storage cavity are directly proportional, and negative pressure is by the water sucking water outlet device 26 in water storage cavity with firing rate water
Stream enters outlet pipeline and uses, and automatic air-intaking exhaust valve 22 makes water storage cavity cross-ventilation, and water storage cavity is by rapid deflation, when being finished water
Unclamp ground pedal.The elastic force of spring 12 pushes water shutoff rubber mat 9, pintongs spool 8 etc. to close water state, and spring valve is closed, firing rate
Water flow disappears, and the tap water transient backflow of outlet pipeline plays antifreeze effect to water storage cavity.When people in routine use pipeline
Interior pressure often will appear fluctuation.Since the emptying amount of water storage cavity is directly proportional to the pressure in pipeline, so the row of water storage cavity
Sky receives the influence of pipeline pressure.Negative pressure when pipeline pressure is relatively low in the firing rate of water flow and threeway 27 reduces, these
Factor results in water storage cavity and is unable to the reflux that Free up Memory or remaining space are not able to satisfy outlet pipe.It is discharged after spring valve closing
The reflux of tap water closes water storage cavity absolutely not space automatic air-intaking exhaust valve 22 in managing, and the tap water of reflux is then from manual
Needle valve 21 is discharged outside chamber, and manual 21 ice period of needle valve opens, and frozen soil layer solution is dynamic to close.Since the hydro-thermal capacity in water pipe is big
It will not freeze the water very little that people move the discharge of needle valve 21 with sailor repeatedly in a short time in short-term, not be especially cold
Manual needle valve 21 can be transferred to drop row pattern state by area, not only ensure that outlet pipe was not frozen and also saved water, but also because the present invention adopts
The generation of artificial drainage is prevented with the mode of foot-operated opening and closing.The still inhalable outlet pipe of water for flowing back into water storage cavity makes
With.It in either case ensure that the absolute emptying of outlet pipe without human intervention again.It is mounted on when being repaired in inspection shaft more
It is convenient, thus it is not only more safe and reliable but also convenient to use than other frost valves, also save water resource.
The valve rod 1 of the utility model, hexagonal tightening nuts 2, gland 3, filler 4, valve deck 5, gasket 6, valve body 7, pintongs
Spool 8, water shutoff rubber mat 9, steel pad 10, clamping screw 11, spring 12, the first gasket 13, valve seat 14, hex union 15, jetting

22, the second sealing ring 23, second baffle 24, third gasket 25, water outlet device 26, threeway 27, suction pipe 28, component is general mark
Quasi- part or component as known to those skilled in the art, structure and principle are all that this technology personnel can be learnt by technical manual
Or known by routine experiment method, the utility model solves the problems, such as to be existing antifreeze mode to be with thermal insulation material by water pipe
It is tightly wrapped up with water valve, effect is unobvious, and there are also using electric-heating belt heating and anti-freezing at high cost, occasionally having power failure that can also freeze can not
It leans on.Manual operation is antifreeze to achieve the purpose that by outlet pipe emptying after being finished water below frost valve embedment frozen soil layer also, but
Outlet pipe is caused to be connected to easily pollution outlet pipe with soakaway, manual operation draining is even there are carelessness both possible bursting by freezing water pipes, and again
It wastes water dangerous reliable.The utility model can prevent the generation of artificial drainage by using the mode of foot-operated opening and closing,
Ice period manual needle valve is not in close state, and the water in water storage cavity will not be discharged.When ice period water without human intervention
Water storage cavity automatic-discharging, is finished water outlet pipe automatic-discharging, and manual needle valve just thinks the relatively low water storage cavity of pipeline pressure not after opening
Energy Free up Memory or water storage cavity remaining space play a role in the drainage when not being able to satisfy outlet pipe reflux, and due to the water in outlet pipe
Thermal capacity is interior in short-term greatly to be freezed, and people move the water very little of needle valve discharge with sailor repeatedly in a short time, than other
Antifreeze anti-not only safe and reliable but also saving water resource.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
