Description
Technical field
The invention belongs to the valve arrangement design field, be specifically related to a kind of exhaust-valve.
Background technology
Solar water heater is owing to save the energy, safety and sanitation, and advantage such as easy to use is very popular, is extensively promoted the use of in cities and towns gradually.But, freeze stifled problem so use winter solar water heater to exist the upper and lower conduit road because northern area is colder winter.Be head it off, adopt the pipeline exhaust-valve now basically, the water in the pipeline is bled off to avoid freezing gambling.
At present, the pipeline emptying valve for solar water heater that circulates on the market has two kinds: one, be to rely on the negative pressure that moment produces in spring pressure and the pipeline to finish emptying.Two, be to adopt electrical ball valve to finish emptying.First kind of exhaust-valve uses when high floor, meeting air inlet in following water, and when causing shower water outlet, water outlet is for a moment given vent to anger for a moment, brings constant to the user; Use is when hanging down floor, because the restriction of receiving spring pressure, the emptying effect is bad; Second kind exists following defective again: 1, instantaneous power failure, bar up hot water, and do not realize tube emptying; When " pipe is logical " 2, is installed, keep away unavoidable air inlet pipe spilling water; 3, electric motor driven gear is can wearing and tearing under limited working life, and the time grow, can occur closing that valve sternly do not cause does and the air inlet pipe spilling water freezing pipeline little by little without a break.
Summary of the invention
The purpose of this invention is to provide a kind of exhaust-valve that overcomes above-mentioned defective, effective emptying pipeline inner product water.
The technical scheme that realizes the object of the invention is: a kind of exhaust-valve comprises main valve and attached valve; Described main valve comprises intake tunnel, exhalant canal, is used for the main electromagnetic type on-off system of conducting and obstruct intake tunnel and exhalant canal; Described attached valve comprises inlet channel, outlet passageway, is used for the attached electromagnetic type on-off system of conducting and obstruct inlet channel and outlet passageway; Be provided with gas port in the exhalant canal of described main valve; The outlet passageway of described attached valve is communicated with gas port in the main valve.
In the technique scheme, described main valve is a normally closed solenoid valve, also to be described main electromagnetic type on-off system intercept when outage intake tunnel and exhalant canal, conducting intake tunnel and exhalant canal when switching on; Described attached valve is a normally open type magnetic valve; Obstruct inlet channel and outlet passageway when also being described attached electromagnetic type on-off system the conducting inlet channel is with outlet passageway, energising when outage.
In the technique scheme, the setting of connecting on circuit of described main valve and attached valve is switched on synchronously and is cut off the power supply.
In the technique scheme, also be provided with the one way stop peturn valve core assembly that is used to prevent the fluid refluence in the outlet passageway of described attached valve.
In the technique scheme, also be provided with the seal channel that is used to be communicated with inlet channel and outlet passageway in the described attached valve, described seal channel is provided with import and outlet; Described one way stop peturn valve core assembly comprises the seal that is used for shutoff sealing channel outlet; Described attached electromagnetic type on-off system can block the movable valve plug of sealing channel entrance when comprising energising.
