Described spool assembly is located at the top of described valve port, described valve bonnet is enclosed within the top of described spool assembly, described supported flange is enclosed within the top of described valve bonnet, the lower end of described housing is fixedly connected with the upper end of described supported flange, described line bag and magnetic axis are located in described housing, the upper end of described magnetic axis is connected with the screw top of described housing, and the lower end of described magnetic axis extend in the center hole of described spool assembly, and described supported flange is fixedly connected with described passage;
The component of described solenoid valve are all metalwork, and described housing, magnetic axis, supported flange, valve bonnet, spool assembly are magnet case.
Described spool assembly comprises valve seat, in described valve seat, be provided with spool, described valve seat is fixedly connected with by the first reed with the upper-end surface of spool, and described valve seat is fixedly connected with by the second reed with the lower end surface of spool, and sealing valve port pad is equipped with in the lower end of the center hole of described spool.
The center hole of described spool and the assembling of described sealing valve port pad drive fit, be and be welded and fixed between described the first reed and the second reed and described valve seat and spool.
Described housing is threaded with described supported flange, and described supported flange and described passage are connected by screw.
Between described spool assembly and described valve port, be provided with spacer.
Between described valve bonnet and described passage, be provided with large metal o-ring, described valve port is put in the cavity of described passage, between described valve port and described passage, is provided with little metal o-ring.
In the present invention, the volume of valve component is little, simple in structure, sealing is reliable, easily sealing, easily processing; Adopt full-metallic component, have very strong corrosion resistance, can be applicable to the Flow-rate adjustment of various gases.
Specific embodiment:
As shown in Figure 1 and Figure 2, in housing 10, be equipped with: line bag 11 and magnetic axis 9.The upper end of magnetic axis 9 for adopting the (not shown) that is threaded, is rotated magnetic axis 9 with the top of housing 10, can make the end face of magnetic axis 9 contact valve bonnet 7 tightly.Housing 10 adopts thread connecting mode to fix with supported flange 8.Four screw (not shown)s are connected through the screw hole of supported flange 8 and four tapped hole (not shown)s of passage 1.The inner chamber of supported flange 8 is equipped with valve bonnet 7.Valve bonnet 7 inner chambers are equipped with spool assembly 6.Between valve bonnet 7 and passage 1, place large metal o-ring 5.Between spool assembly 6 and valve port 3, place spacer 4, can highly choose the quantity that spacer 4 is installed according to opening of valve port.Valve port 3 is put in the cavity of passage 1, places little metal o-ring 2 between valve port 3 and passage 1.
As shown in Figure 3, Figure 4, spool assembly 6 is made up of the first reed 6.1, valve seat 6.2, spool 6.3, sealing valve port pad 6.4 and the second reed 6.5.Sealing valve port pad 6.4 relies on drive fit to squeeze in the center hole of spool 6.3; Then put in the cavity of valve seat 6.2; The first reed 6.1 is welded and fixed in upper-end surface with valve seat 6.2 and spool 6.3; The second reed 6.5 is welded and fixed in lower end surface with valve seat 6.2 and sealing valve port pad 6.4.
The working principle of specific embodiment is:
In the time of power-off, spool 6.3 is still in a certain position in spool assembly 6, and has certain distance (distance is determined by the quantity of the spacer 4 of selecting) with valve port 3, and now, flow is maximum.After 11 energisings of line bag, valve seat 6.2 produces suction to spool 6.3, and spool 6.3 moves down, and regulates input voltage value, and valve seat 6.2 changes along with the variation of input voltage value the suction of spool 6.3.Therefore, the position that spool 6.3 is still in spool assembly 6 changes along with the variation of input voltage value, sealing valve port pad 6.4 relies on drive fit to squeeze in the center hole of spool 6.3, the mobile movement that drives sealing valve port pad 6.4 of spool 6.3, thereby distance between sealing valve port pad 6.4 and valve port 3 is changed, realize the size of adjusting flow.In the time that input voltage value increases to a certain value, making distance between sealing valve port pad 6.4 and valve port 3 is zero, and flow is now just zero, and now this solenoid valve has been realized the function of closing.
In specific embodiment, the effect of each part is:
11 effects of line bag are that energising produces magnetic field.
Supported flange 8 effects are to bear pressure, tighten the clamping bolt (not shown) between supported flange 8 and passage 1, pressure valve bonnet 7 downwards, the downward pressure valve core assembly 6 of valve bonnet 7.
Valve bonnet 7 act as: valve bonnet 7, large metal o-ring 5 and passage 1 form the space of sealing, and gas can not leak outside; The permeability magnetic material of valve bonnet 7 can reduce the loss of the magnetic line of force effectively.
In spool assembly 6, valve seat 6.2, spool 6.3 are permeability magnetic material, and valve seat 6.2 produces downward suction to spool 6.3, and spool 6.3 can move up and down under the effect of electromagnetic force.The first reed 6.1, the second reed 6.5 can guarantee that spool does the motion of straight line.Sealing valve port pad 6.4 be mainly sealing valve port high because its sealing surface requires, independently sealing valve port pad is to be to reduce difficulty of processing.
The quantity of the effect increase and decrease spacer 4 of spacer 4, the peak flow values of adjusting valve port 3.
The above; only for preferably embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
