Abstract
The invention discloses an electromagnetic valve for draining a pipeline of a solar water heater and relates to a special electromagnetic valve which has the advantages of simple structure and low cost and aims to drain a water transmission pipe. The electromagnetic valve is arranged in the highest position of the water transmission pipe. When a valve core of the valve is lifted, an air inlet hole and an air outlet hole are communicated, and air enters the pipeline to drain water. When the valve core of the valve is dropped, the air inlet hole and the air outlet hole are completely blocked, and hot water in a water tank can be sucked out by using a siphon principle. A valve body can be matched with a computer controlled display for draining the pipeline of the fully automatic solar water heater, and the purpose of automatically draining the water transmission pipe of the solar water heater can be preferably realized.
Description
Technical field the present invention relates to a kind of gas phase solenoid valve, particularly a kind of solar water heater conduit pipe solenoid valve of supplying gas.
The existing solar water heater of background technique is very inconvenient when the use in winter of cold area, and Main Problems is: aqueduct very easily frozen block bursting by freezing in the situation of not doing the ribbon heater protection; After all needing before the each use of user in the winter time to the ribbon heater energising ice in the conduit pipe to be melted first; after again frozen water being drained could to hot water; solar water heater need add ribbon heater and insulating sponge protection because of its aqueduct; namely wasted electric power energy like this, it is attractive in appearance to have affected again building.
A kind of preferably solution is the purpose that adopts the mode that the water in the waterpipe is emptying to reach preventing freeze in winter and open the valve instant-heating and outlet hot, but aqueduct is carried out the emptying electromagnetic valve that adopts but not to be had special-purpose, conventional electromagnetic valve is because of its complex structure, technical order is high, and cost is high and affected and apply.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, with low cost, but can satisfy the supply gas special electromagnetic valve of emptying needs of conduit pipe, this solenoid valve comprises valve body, valve pocket, spool and drive part form, it is characterized in that: be provided with gas-entered passageway and outlet passageway in the described valve body, wherein the inner port of outlet passageway has sealing surface, is valve pocket in the front of inner port, is provided with spool in valve pocket, towards the one side of sealing surface a sealing gasket is set at spool, the another side of spool arranges a connecting rod, and spool is connected with iron core by connecting rod, at spring of the other end connection of iron core, an air core coil at the iron core overcoat, the heart of coil is the part of valve pocket, a gland is set in the outer end of coil coil and valve body are linked togather, and spring is pushed down.When described gland is planar when arranging, solenoid valve no electric circuit when static, spring is pressed to air outlet hole with spool and air outlet hole is blocked, and solenoid valve is the normal close type valve, as shown in Figure 1.When described gland is " ∩ " when shape arranges, solenoid valve no electric circuit when static, spring is pulled away from air outlet hole with spool makes air outlet hole unimpeded, and solenoid valve is the open type valve, as shown in Figure 2.
In actual applications solenoid valve is arranged at the highest point of conduit pipe, when the spool of this valve was mentioned, inlet hole was communicated with air outlet hole, it is emptying with water that air enters pipeline, when the spool of this valve falls, inlet hole and air outlet hole are blocked fully, can be with the hot water sucking-off in the water tank by siphon principle.This valve body can cooperate with automatic solar water heater pipe evacuation computer control display instrument, realizes preferably the automatic-discharging purpose of solar water heater conduit pipe.
The present invention is simple in structure, and precision is not high, and cost is low.Not consuming electric power during normality uses safety, is convenient to penetration and promotion and uses.
Description of drawings
Fig. 1 is normal close type structural drawing of the present invention
Fig. 2 is open type structural drawing of the present invention
Among the figure: 1-gas-entered passageway, 2-valve body, 3-coil, 4-gland, 5-spring, 6-iron core, 7-spool, 8-outlet passageway.
Embodiment: solar energy water heater pipe emptying solenoid valve, the normal close type valve is as shown in Figure 1: the inner port of outlet passageway 8 is mouths that unique needs can seal up in valve body 2, this port is processed into smooth flat, it can be sealed in the time of above spool 7 drops on.Gland 4 is a flat board, and gland is with spring 5 compressions usually, and it is hollow that spring extrudes coil with iron core 6.When to coil electricity, it is hollow that iron core is inhaled into coil, and spool is opened.
The open type valve is as shown in Figure 2: difference is that gland 4 is " ∩ " shape structure, and gland stretches spring 5 usually, and it is hollow that spring is pulled out coil with iron core 6.When to coil electricity, it is hollow that iron core is inhaled into coil, and spool 7 is dropped on above the inner port of outlet passageway 8 and it is sealed.
Claims (3)
