Description
Technical field
The utility model relates to a kind of electromagnet cut off valve.
Background technique
Solenoid valve is used for control hydraulic flow direction, is the automation foundation element of controlling fluid.General solenoid valve mainly is comprised of Electrical heads, electromagnet, main valve body and diaphragm etc.
Because the restriction of structure, although that main valve body is imported and exported latus rectum is very large, be far smaller than the inside nominal diameter (abbreviation undergauge) of valve design or standard at the actual latus rectum of main valve body, make the Cv value of valve very large (the Cv value is the negotiability index of valve).
Calculate according to actual tests, the leading type two-position two-way electromagnetic stop of the ordinary construction of an inside nominal diameter DN20mm, its actual latus rectum on main valve body may be less than DN10mm, when being 0.5kg/s by valve flow, the valve inlet outlet pressure differential is 0.8MPa, when flow reached 1kg/s, its inlet outlet pressure differential can reach more than the 3MPa, and the ball valve pressure reduction of identical latus rectum only is 0.1MPa.
This just causes when selecting two-position two-way electromagnetic stop, otherwise according to the electromagnet cut off valve of the identical latus rectum of pipeline selection for nominal diameter, but must improve valve inlet pressure, cause the design pressure of hydraulic system power source and pipeline greatly to increase.
Another way is exactly to select the electromagnet cut off valve more much larger than actual pipeline latus rectum to reduce pressure drop to guarantee the actual circulation area.
These two kinds of ways have all improved the design objective of hydraulic system greatly, and pipeline structure is complicated, cost increases.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of leading type two-position two-way electromagnetic stop, can eliminate the undergauge phenomenon, improves the Cv value of valve, reduces valve at the inlet outlet pressure differential of large flow rate working conditions lower valve.
A kind of leading type two-position two-way electromagnetic stop of the present utility model comprises: be formed with fluid input and outlet main valve body, be arranged on main valve body inner chamber spool support, conducting or close the spool of described main valve body and be arranged on magnetic switch on the described main valve body, described main valve body has and connects described entrance and exit and diameter more than or equal to the inner chamber of described entrance and exit; Be formed with cavity on the described spool support, described spool is removable to be installed in the described cavity, described spool one end is resisted against on the described spool support by spring, the other end of described spool have can be pressed against described outlet and go out the airtight seal face that cooperates of interruption-forming and described fluid to the face of exerting pressure of exerting pressure to described spool away from described Way out with described; Be formed with on the described spool by the damping hole of the end face that described spring is installed to the circumferential surface extension of described spool, be formed with the gap of the described inner chamber of conducting and damping hole between described spool and the described spool support; Be formed with pod apertures with described outlet and described cavity conducting at described main valve body and spool support, described pod apertures is by described magnetic switch control opening and closing.
Preferably, the entrance at described main valve body also is provided with the bracket lock tight coupling.
Preferably, described magnetic switch comprises the electromagnet that the described pod apertures unlatching of control or the Electrical heads of closing and this Electrical heads of control are moved.
During the utility model outage, the fluid of inner chamber enters cavity via gap, damping hole, spring pressure and hydrodynamic pressure to Way out that this moment, spool was subject to, because making a concerted effort greater than fluid to the face applied pressure of exerting pressure of the two, spool moves to Way out, thereby closely be pressed against in the outlet of main valve body valve closing;
And when energising, magnetic switch control makes the pod apertures conducting, and the fluid in the cavity just flows out to outlet along pod apertures, at this moment the spring force that is subject to of spool less than fluid to the face applied pressure of exerting pressure, effect lower valve core at hydrodynamic pressure moves valve open to the direction away from outlet.
The utility model since as the diameter of the main valve body inner chamber of the fluid course of actual circulation more than or equal to import and outlet inside nominal diameter, therefore can eliminate the pressure reduction problem that valve brings because of the undergauge phenomenon.Simultaneously, the utility model is simple in structure, and compactness is installed, and reliable operation because machining accuracy and difficulty reduce, has also significantly reduced cost.

Fig. 2 is the B section enlarged diagram of Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model comprises: main valve body 3, spool support 6, spool 4 and magnetic switch 1.Concrete structure is:
Be formed with fluid input 12 and outlet 11 on the main valve body 3, main valve body 3 has perforation entrance 12 and outlet 11 and diameter more than or equal to the inner chamber 14 of entrance 12 and outlet 11.
Spool support 6 is arranged in the inner chamber 14 of main valve body 3, is formed with the cavity 13 that spool 4 is installed at spool support 6.Be formed with pod apertures 9 with outlet 11 and cavity 13 conductings at main valve body 3 and spool support 6.
Spool 4 removable being installed in the cavity 13, spool 4 one ends by spring 5 resilient abutment on spool support 6, that the other end has outlet of can being pressed against 11 and form the airtight seal faces that cooperate 15 and fluid to the face of exerting pressure 16 of exerting pressure to spool 4 away from outlet 11 directions with outlet 11.Be formed with on the spool 4 by the end face of mounting spring 5 to the damping hole 8 that the circumferential surface of spool 4 extends, be formed with the gap 17 of conducting inner chamber 14 and damping hole 8 between spool 4 and the spool support 6.When the seal face 15 of spool 4 is pressed against in the outlet 11, main valve body 3 is closed, when the seal face 15 of spool 4 leaves outlet 11, conducting main valve body 3.
