Description
Technical field
The invention belongs to the valve arrangement design field, be specifically related to a kind of exhaust-valve.
Background technique
Solar water heater is owing to save the energy, safety and sanitary, 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 electric 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 pipe evacuation; When " pipe is logical " 2, is installed, keep away unavoidable suction tude spilling water; 3, electric motor driven gear is can wearing and tearing under limited operating life, and the time grow, can occur closing that valve sternly do not cause does and the suction tude 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 technological 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 gas-entered passageway, outlet passageway, is used for the attached electromagnetic type on-off system of conducting and obstruct gas-entered passageway 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 solenoid valve; Obstruct gas-entered passageway and outlet passageway when also being described attached electromagnetic type on-off system the conducting gas-entered passageway 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 sealing channel that is used to be communicated with gas-entered passageway and outlet passageway in the described attached valve, described sealing channel is provided with import and outlet; Described one way stop peturn valve core assembly comprises the Sealing 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.
In the technique scheme, described one way stop peturn valve core assembly also comprises the elastic component that is used to Sealing that reseting elasticity is provided.
In the technique scheme, described movable valve plug is arranged on the top of the sealing channel of attached valve; Described Sealing is arranged on the below of described sealing channel; Described elastic component is arranged on the spring of Sealing below, and the one end is against on the attached valve outlet passageway inwall, and the other end is against on the described Sealing.
In the technique scheme, the basic shape of described Sealing is a T shape, comprises circular sealed department and guide portion; Described sealed department and guide portion are combined to form the T font; Be provided with the slide opening that matches with described guide portion in the described outlet passageway.
In the technique scheme, the bottom margin place of described sealed department is provided with the annular boss to lower convexity, forms an annular recess between described annular boss and the described guide portion.
In the technique scheme, described main valve and attached valve are arranged side by side, and are arranged on the same side of described intake tunnel.
The present invention has positive effect: among (1) the present invention, 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.This structure makes the present invention in use, and under the control of ABAP Adapter, described main valve is used for guaranteeing the normal break-make of pipeline inner fluid; Described attached valve is used for when pipeline is through-flow, intercept gas-entered passageway and outlet passageway, prevent that the pipeline inner fluid from overflowing from the admission line of attached valve, when in pipeline cutout, pipeline, causing in the pipeline ponding owing to the vacuum suction effect, conducting intake tunnel and exhalant canal, make the ponding in the pipeline to communicate, thereby the ponding in the pipeline can be flowed out along water tap that is arranged on the pipe end place or shower nozzle with ambient atmosphere; Because the smooth ponding in the emptying pipe, so can not cause pipeline and stop up or break because ponding freezes.
(2) among the present invention, main valve is selected normally closed solenoid valve for use, 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; Attached valve is selected normally open solenoid valve for use; Obstruct gas-entered passageway and outlet passageway when also being described attached electromagnetic type on-off system the conducting gas-entered passageway is with outlet passageway, energising when outage.This structure is comparatively reasonable, in actual use, can be the setting of on circuit, connecting of main valve and attached valve, switch on synchronously and cut off the power supply, main valve is open-minded during energising, and attached valve is closed circuit synchronously, and the pipeline inner fluid normally circulates; During outage, main valve is closed circuit, and attached valve is open-minded synchronously, makes the interior ponding of pipeline communicate with atmosphere, is convenient to emptying.
