In addition, be understandable that, the upper end of outlet pipe 63 is arranged on the position of roof of contiguous inner bag 62, in the time of water heater 60 normal water outlet, water inlet pipe 65 is also in open mode, and the water in inner bag 62 is that hydraulic pressure inner bag 62 being produced by the water in water inlet pipe 65 is discharged the water in inner bag 62 from outlet pipe 63, thereby makes the water in whole inner bag 62 be running water, is unfavorable for the deposition of dirt.Therefore,, according to an embodiment of the present utility model, the upper end of outlet pipe 63 is formed with arc fold bending.Thus, by arc fold bending is set, can facilitate the water outlet of outlet pipe 63.
Concrete structure about intake and exhaust water-drainage solenoid valve is not particularly limited, there is gas passage and exhalant canal as long as satisfied to realize the requirement of outlet pipe 63 air inlets, exhaust and water outlet, alternatively, as shown in Fig. 3 to Fig. 7, according to an embodiment of the present utility model, intake and exhaust water-drainage solenoid valve comprises: the control piece (not shown) of body 10, load module for being connected with outlet pipe 63, motion assembly and the motion of controlled motion assembly.
Particularly, body 10 is provided with water inlet end 11 and water side 12, and water inlet end 11 is connected with water side 12.On body 10, be also provided with inlet end 13 and outlet side 14, inlet end 13 is connected with outlet side 14.Load module is located on water inlet end 11, and it is interior and changeable between primary importance and the second place that motion assembly is located at body 10, in the time that motion assembly is positioned at primary importance, and inlet end 13 and outlet side 14 conductings; In the time that motion assembly is positioned at the second place, inlet end 13 and outlet side 14 disconnect.
Thus, according to the intake and exhaust water-drainage solenoid valve of the utility model embodiment, by controlling together with the valve combination of air inlet and the valve of giving vent to anger and control water outlet, and by the opening and closing of this intake and exhaust water-drainage solenoid valve of motion assembly control, realize the automatic control of water heater 60 air inlets or exhaust and water outlet; In addition, by intake and exhaust water-drainage solenoid valve and water-through valve combination, improve the integrated level of valve, reduce and needed the valve of assembling and the assembling of pipeline, can make the Assembly interface of water heater 60 tail off, in the time producing in enormous quantities, be not prone to many bad connections and drainage, and improved efficiency of assembling, reduced preparation cost.
Particularly, in the time of water heater 60 normal work, water inlet from water inlet pipe 65, the motion assembly of intake and exhaust water-drainage solenoid valve is positioned at the normally closed second place, and inlet end 13 and outlet side 14 disconnect, water inlet end 11 and water side 12 conductings, normal water outlet in outlet pipe 63, blow-off pipe 64 cuts out; In the time that needs carry out blowdown processing to water heater 60, close the switch being connected with jet pipe, current in water inlet end 11 and water side 12 are static, open blow-off pipe 64, controlled motion assembly moves to primary importance, inlet end 13 and outlet side 14 conductings, and gas flows into inlet end 13 and enters in water heater 60 from outlet side 14, ensure water heater 60 internal gas pressure balances, thereby discharge smoothly the sewage in water heater 60; After blowdown completes, close blow-off pipe 64, opening water inlet pipe 65 intakes to water heater 60, the water that enters water heater 60 is discharged the air in water heater 60 from intake and exhaust water-drainage solenoid valve, after in water heater 60, water is filled, controlled motion assembly returns back to the second place, and inlet end 13 and outlet side 14 disconnect, and water heater 60 is replied normal operating conditions.
According to an embodiment of the present utility model, water inlet end 11 shares a port and is connected with the lower end of outlet pipe 63 with inlet end 13.In other words, water inlet end 11 both can be used as the water inlet of intake and exhaust water-drainage solenoid valve, can be used as again air inlet.Under normal condition, water inlet end 11 and water side 12 conductings, inlet end 13 and outlet side 14 disconnect, the switch opens on jet pipe, the water in water heater can only be discharged from water side 12; In the time that water heater needs blowdown, inlet end 13 and outlet side 14 conductings, owing to there is draught head inside and outside water heater, gas enters water heater from outlet side 14 enters inlet end 13, and the water in water side 12 can not spill from outlet side 14; After water heater blowdown completes when intaking in water heater, the gas entering in the water extruding water heater of water heater makes it enter intake and exhaust water-drainage solenoid valve from inlet end 13, and switch on jet pipe cuts out, the water in water side 12 is static, and the gas in water heater can only be discharged from outlet side 14.
Thus, water inlet end 11 and inlet end 13 are incorporated into same port and carry out exhaust or draining, exhaust and drainage procedure do not produce conflict, all can normally carry out, under the prerequisite that can realize in the function that ensures intake and exhaust water-drainage solenoid valve, further reduce the number of ports of intake and exhaust water-drainage solenoid valves, also reduced arranging of water heater upper pipeline simultaneously, improve efficiency of assembling, reduced preparation cost.
On intake and exhaust water-drainage solenoid valve, the relation of arranging of each port can rationally regulate according to the structure of water heater, alternatively, according to an embodiment of the present utility model, angle between the axis of the axis of water inlet end 11 and water side 12 is 90 °, and inlet end 13 is formed as straight tube-like path with outlet side 14 conductings.That is to say, between water inlet end 11 and water side 12, be substantially formed as L shaped structure, between inlet end 13 and outlet side 14, be communicated with and be formed as through-type structure.Thus, the straight length minimum of assembling between the water inlet end 11 of the intake and exhaust water-drainage solenoid valve of this structure and water side 12, the impact of the structure of the anti-electric wall shell on water heater 60 is also minimum, be convenient to assembling, through-type structure air inlet or the exhaust rapidly of inlet end 13 and outlet side 14, ensures the normal operation of water heater.And the intake and exhaust water-drainage solenoid valve production and processing ratio of this structure is easier to, and can reduce difficulty of processing, cuts down finished cost.
In embodiment of the present utility model, intake and exhaust water-drainage solenoid valve switches between primary importance and the second place by control piece controlled motion assembly, thereby realize air inlet and the exhaust of water heater 60, wherein said control piece can be for being located at switch or the automatic program etc. on water heater 60, this structure is appreciated that to those skilled in the art and easily realizes, therefore repeats no more.
As shown in Figure 6 and Figure 7, according to an embodiment of the present utility model, between inlet end 13 and outlet side 14, be provided with cross section and be formed as annular breather pipe 15, the axis of breather pipe 15 is vertical with the axis of water side 12 with inlet end 13 respectively, the outer shroud of breather pipe 15 and inlet end 13 conductings, one end sealing of breather pipe 15, the other end and outlet side 14 conductings.When motion assembly is positioned at primary importance, the other end of breather pipe 15 opens wide and outlet side 14 conductings, the other end of closed vent pipe 15 when motion assembly is positioned at the second place.That is to say, the sealing of the right-hand member of breather pipe 15, motion assembly is located at the left end of breather pipe 15, and the left end of motion assembly closed vent pipe 15 while moving right the second place, and breather pipe 15 disconnects with outlet side 14; When motion assembly moves left, the left end of breather pipe 15 opens wide, breather pipe 15 and outlet side 14 conductings.
Particularly, in the time that water heater needs exhaust, gas in water heater flows into intake and exhaust water-drainage solenoid valve from inlet end 13, the gas that flows into intake and exhaust water-drainage solenoid valve, first flows into cross section and is formed as in annular breather pipe 15, and controlled motion assembly moves to primary importance, motion assembly is away from the left end of breather pipe 15, the left end of breather pipe 15 opens wide, breather pipe 15 and outlet side 14 conductings, and gas is discharged from outlet side 14.After water heater exhaust completes, controlled motion assembly is positioned at the second place, the two ends of breather pipe 15 are all sealed, gas in inlet end 13 can only rest in breather pipe 15 after flowing to breather pipe 15, can not flow in outlet side 14, now, the gas circuit of water heater 60 disconnects, and water heater 60 can not exhaust.
Otherwise in the time that water heater needs air inlet, gas enters in water heater enter inlet end 13 by breather pipe 15 from outlet side 14 after again, the course of work of its course of work and water heater exhaust is similar, therefore repeats no more.
Thus, by between inlet end 13 and outlet side 14, breather pipe 15 being set, move upward to open wide or the left end of closed vent pipe 15 at right and left by controlled motion assembly, can realize conducting or the disconnection of intake and exhaust water-drainage solenoid valve, simple and reasonable, it is convenient to control.
Concrete structure about motion assembly is not particularly limited, as long as meeting, it can in the time being positioned at primary importance, make inlet end 13 and outlet side 14 conductings, the requirement that makes inlet end 13 and outlet side 14 disconnect in the time being positioned at the second place, alternatively, according to an embodiment of the present utility model, motion assembly comprises: push rod 31, elastic component 32, soup stick 33, sealing ring 34 and control valve 35.
