Embodiment
This embodiment is with the detailed related technological scheme of the utility model of introducing, so that those skilled in the art's understanding and enforcement.
A kind of solenoid valve, the electromagnetic power parts that comprise valve body and be provided with electromagnetic wand, described valve body comprises the connecting port and the valve cylinder of entrance point, outlet end, connection entrance point and outlet end, the piston that is used to block connecting port that described valve cylinder comprises the valve cylinder body and is positioned at the valve cylinder body, described electromagnetic wand comprises electromagnetic wand body and the connecting end that is connected with piston, it is characterized in that the circlip that described piston comprises piston cavity, is positioned at the gland on the piston cavity and fastens described gland;
Described connecting end end is provided with first jut, and gland is provided with for what connecting end slipped into and slips into Chang Kou, and the interior bore of described gland is less than the bore of first jut.
On the basis of above scheme, this embodiment will be mainly from the Placement of improving connecting end and piston, improve valve and easily describe three aspects of sealability of the property opened and raising solenoid valve.One, at the description of the Placement of improving connecting end and piston
After connecting end entered piston cavity, this embodiment found, the slipping into Chang Kou and in use damage than being easier to of gland.
Reason is that first jut can't guarantee tight the contact with gland, makes the motion of connecting end can't guarantee consistent with the motion of gland; After electromagnetic wand moves, first jut that is arranged on the connecting end end can clash into gland, after using a period of time, the slipping into long mouthful and can deform of gland, after slipping into the bore of long degree of lip-rounding calibre-changeable greater than first jut, first jut can be shaken off in piston cavity by slipping into long mouthful, and connecting end loses with piston at this point and is connected, thereby causes solenoid valve to lose efficacy.
One is managed to solve the technical measures that slip into the long mouthful of problem of in use damaging easily is to be provided with connecting end is supported the post that supports to gland on described piston cavity, should support post and can act directly on first jut, just as what Fig. 2 showed.
The technical measures that another solution slips into the long mouthful of problem of in use damaging easily are at described piston cavity the gland groove of placing gland to be set, after fastening by circlip, can be fixed on the gland groove, and can not pitch along with the effect of first jut.
Two, at improving the easily description of the property opened of valve
In order to strengthen the Yi Kaixing of valve, this embodiment has been continued to use the way of prior art, promptly in propping up, be provided with the pilot valve passage, for example as shown in Figure 2, gas can be from entrance point 21 along piston and the gap between the valve cylinder body 23 enter in the piston cavity 6, as long as electromagnetic wand 17 is toward rising, the gas that enters in the piston cavity 6 can enter outlet end 20 by the pilot valve passage, thereby impel the air pressure in the piston cavity 6 to reduce, help reducing the draught head between piston cavity 6 and the outlet end 20, make valve become and open easily.
On the other hand, also between the piston of solenoid valve and valve cylinder body, set up guide element between this embodiment, this guide element can comprise piston ring and be enclosed within piston ring spring on the piston ring that the piston area of described piston is provided with the groove that inserts for piston ring.Thereby the easier debugging of piston is assembled in the valve cylinder body.
Three, at the description of the sealability that improves solenoid valve
Electromagnetic wand is blocked the pilot valve passway and the leakage problem that produces is of long duration, as shown in Figure 1, a kind of existing solenoid valve that is applied to steam tube, gas in entrance point 5 can enter piston by gap between valve cylinder body and the piston 7 and the pressure guide hole that is arranged on the gland 9, when described existing solenoid valve need be opened, steam in the piston 7 can enter outlet end 4 by pilot valve passage 13, and when described solenoid valve need cut out, electromagnetic wand 8 relies on the gravity of self to descend and blocks in the process of pilot valve passage 13, can be because the impact of air-flow, the shakiness that descends consequently can accurately not aimed at pilot valve passage 13, causes leakage.
As a kind of selection, this embodiment solves the described leakage problem of epimere literal by following structure:
Set up valve cylinder cap and electromagnetic wand spring that the power supply bar magnet passes on the valve cylinder, the electromagnetic wand body is provided with second jut, then electromagnetic wand spring one end is connected with described second jut, and the other end is connected with the valve cylinder cap.Because electromagnetic wand is connected with piston, thus the electromagnetic wand spring to the elastic force of electromagnetic wand with indirect acting on the piston.When piston is blocked connecting port (also closed condition), the electromagnetic wand springback is returned, and electromagnetic wand is resetted, thereby the impact air-flow of opposing electromagnetic wand in the decline process makes the anti-leakage ability of the described solenoid valve of this embodiment get a promotion.
In addition, block connecting port and the leakage problem that produces as piston, a kind of existing solenoid valve that is applied to steam tube that Fig. 1 showed, its shutoff packing ring is directly to be stuck on the piston, like this, uses a period of time mouth, come off easily, thereby cause solenoid valve to lose efficacy from correspondingly draw-in groove.
This embodiment is strengthened the stationkeeping ability to the shutoff packing ring for this reason at least, specifically need set up one can be to the pressure exerting arrangement of major general's shutoff packing ring to described pad groove direction pressure, this pressure exerting arrangement is by being fixed on the double-screw bolt and be arranged on the nut of exerting pressure on the double-screw bolt of exerting pressure and come at least the shutoff packing ring location of exerting pressure of exerting pressure of piston cavity bottom, and the external diameter of certain described nut of exerting pressure should be greater than the internal diameter of shutoff packing ring.
Be in and strengthen the consideration in working life of shutoff packing ring, can set up in piston cavity bottom at shutoff packing ring and the spring washer between the nut of exerting pressure, certainly the external diameter of spring washer at least should be greater than the internal diameter of shutoff packing ring, and the internal diameter of spring washer is less than the external diameter of the nut of exerting pressure.
