Describe in detail according to the high-pressure solenoid valve 5 of the utility model embodiment below with reference to Fig. 1-Fig. 5, the waste pipe 4 that this high-pressure solenoid valve 5 is connected on purifier 100 is used to open or close waste pipe 4.
According to the high-pressure solenoid valve 5 of the utility model embodiment, comprising: the valve body 50 of hollow, valve head 51, seal cover 52, spool 53, first spring 54 and the second spring 55.Wherein, valve body 50 comprises the first chamber 501 of connection and the second chamber 502, first chamber 501 has opening.Valve head 51 is located at opening part, and valve head 51 is provided with water inlet 511 and delivery port 512, and valve head 51 is provided with sealing ring 513.Seal cover 52 to be located in the first chamber 501 and to be located on valve head 51, and seal cover 52 is provided with the first passage 520 and the second channel 521 being communicated with delivery port 512 that are communicated with water inlet 511, and seal cover 52 contacts with sealing ring 513.Wherein be understandable that, the dischargeable capacity for holding water that should be greater than for the dischargeable capacity holding water in valve head 51 in valve body 50.
In the concrete example of Fig. 1, valve head 51 is provided with the cavity 514 towards the first chamber 501 opening, and cavity 514 is communicated with delivery port 512.Sealing ring 513 is positioned on the open end of cavity 514, and when seal cover 52 is located on valve head 51, second channel 521 is directly communicated with cavity 514.In the example of fig. 3, second channel 521 is the central small hole of seal cover 52.
Spool 53 is located in the second chamber 502 and one end of spool 53 movably and extend in the first chamber 501.First spring 54 is located in the second chamber 502 and two ends of the first spring 54 and is connected often to drive spool 53 to move with shutoff second channel 521 towards seal cover 52 with the other end of spool 53 with the sidewall of the second chamber 502 respectively.That is, the first spring 54 applies the active force of driving spool 53 towards seal cover 52 movement to spool 53 all the time.When spool 53 contacts with seal cover 52, spool 53 shutoff second channel 521 makes the first chamber 501 spaced apart with delivery port 512.
Be enclosed within outside second spring 55 on spool 53, the two ends of the second spring 55 are connected often to drive spool 53 to move towards seal cover 52 with shutoff second channel 521 with seal cover 52 with the sidewall of the first chamber 501 respectively.That is, the second spring 55 is positioned at the active force that the first chamber 501, second spring 55 applies spool 53 to drive spool 53 towards seal cover 52 movement all the time.
Be understandable that, high-pressure solenoid valve 5 also comprises the parts such as coil, electric control element, and the electric control principle of high-pressure solenoid valve 5 is identical with the electric control principle of the high-pressure solenoid valve of prior art, is not just described in detail here.
When high-pressure solenoid valve 5 is in running order, as shown in Figure 4, under the signal of telecommunication controls, the active force that spool 53 overcomes the first spring 54 moves (as shown in Figure 4 towards the direction away from seal cover 52, spool 53 moves right), spool 53 departs from seal cover 52, water enters into (the right side cavity namely entering into seal cover 52 is interior) in the first chamber 501 of valve body 50 from water inlet 511 by the first passage 520 seal cover 52, and the second channel 521 of the water in valve body 50 again on seal cover 52 enters into delivery port 512 and discharge.Owing to being greater than the dischargeable capacity for holding water in valve head 51 in valve body 50 for the dischargeable capacity holding water, that is, the right effective area of seal cover 52 is greater than left side effective area, namely the right pressure of seal cover 52 is greater than left side pressure, and seal cover 52 is sealed and matched with the sealing ring 513 on valve head 51.In the example of fig. 4, first the water flowed out from second channel 521 flow in cavity 514, then discharge from the delivery port 512 of valve head 51.
When high-pressure solenoid valve 5 is in off working state, as shown in Figure 5, under the effect of the first spring 54, spool 53 contacts with shutoff second channel 521 with seal cover 52, and that is, spool 53 is in the second channel 521 on seal cover 52 state of being sealed and matched.Simultaneously under the acting in conjunction of the second spring 55 and the first spring 54, seal cover 52 is sealed and matched with the sealing ring 513 on valve head 51, after water to enter into the right side cavity of seal cover 52 by the first passage 520 seal cover 52 from water inlet 511, can not be drained in delivery port 512 from the second channel 521 of seal cover 52 further, delivery port 512 can not be entered into by the gap between the sealing ring 513 on valve head 51 and seal cover 52, ensure that high-pressure solenoid valve 5 positiver sealing under lower pressure.In the example of hgure 5, the water entered on the right side of seal cover 52 after cavity can not enter in cavity 514 from second channel 521, can not be entered in cavity 514 by the gap between sealing ring 513 and seal cover 52, thus ensure that the water of water inlet 511 cannot be discharged from delivery port 512.
Existing high-pressure solenoid valve should be in normally off in theory when not working, but due to power limited, the elastic force of the first spring is less, cause the seal ring seal on seal cover and valve head unreliable, water can enter in the cavity of valve head by the gap between sealing ring and seal cover, flow out from the delivery port of valve head again, thus cause high pressure valve seepy question under lower pressure.
According to the high-pressure solenoid valve 5 of the utility model embodiment, by being provided with the second spring 55 between seal cover 52 and valve body 50, compensate for the not enough problem of sealing reliability between seal cover and the sealing ring of valve head that existing high-pressure solenoid valve causes because the spring force of the first spring is little, ensure that in a non-operative state, the water entered in valve body 50 from water inlet 511 can not be discharged from delivery port 512, ensure that high-pressure solenoid valve 5 sealing reliability in a low voltage state, and the load power of high-pressure solenoid valve 5 can not be increased.
As shown in Figure 1, Figure 4 and Figure 5, in specific embodiment of the utility model, the second spring 55 is turriform spring, and the large end of the second spring 55 is connected with the sidewall of the first chamber 501.
