Abstract
The utility model discloses a high frequency electromagnetic valve, belonging to an electromagnetic valve used for automatic control. The high frequency electromagnetic valve is characterized in that the main valve core is designed as a self centering sealing structure. The self centering sealing structure is composed of a main valve ring with a slant face interface, a hollow centering linkage bar, a return spring, a spring guard bar, and a cone shape sealing head. The guide valve core is designed as a self centering sealing structure. The self centering sealing structure is composed of a guide valve ring with a slant face interface, a centering return spring, and a cone shape sealing head. The utility model has the advantages of good tightness, energy saving, light weight, clamp preventing, resistant high temperature, high working frequency, etc. The high frequency electromagnetic valve has the advantages of lowering the height of the outlet of the sealing seat, the loss of the fluid head is reduced, the diameter of the valve body is reduced, and the material is saved.
Description
The utility model belongs to automatic control solenoid valve.
General conventional solenoid valve, between guide valve core and the magnetic shield, formed gap directly enters the bits in the fluid between main valve plug and the valve body easily, causes to cause valve body wearing and tearing and guide valve core, main valve plug to be blocked and out of control.In addition because the gap between main valve plug and the valve body can not be very big, therefore when fluid temperature (F.T.) too high (as being steam), because thermal expansion is blocked main valve plug and can't work.
General conventional solenoid valve, its guide valve core and main valve plug all adopt the plane sealing mode usually, and the easy Off center of sealing surface is difficult to time inferior coincideing when therefore working, like this, occur easily revealing.
The purpose of this utility model is to provide a kind of and has that anti-sticking is durable, sealability is better, frequency of okperation height, withstand high temperatures, the solenoid valve that the fluid head loss is little.
The purpose of this utility model is finished by following technical proposals.Its main valve plug is designed to by main slip ring, hollowly decides the core linkage rod, return spring, the self contering sealing configuration that spring guard bar and cone seal head are formed; Its guide valve core is designed to by slide guide ring, centering return spring, the self contering sealing configuration that the cone seal head is formed.This self contering sealing configuration, guaranteed the axial Self-centering Action of main valve plug and guide valve core, because main, pilot valve ring has the inclined-plane interface, certain elastic telescopic effect is arranged, often maintenance and valve body or magnetic shield fit, make sealability better, isolated the bits in the fluid effectively.
The utility model has strengthened the gap between main valve plug and the valve body, and its spool and valve body remain contactless state, has avoided because the phenomenon that thermal expansion is blocked spool.
The utility model has reduced the height of the exit seal seat on the valve body, and its height thereby has reduced the fluid head loss below the center line of entrance driveway, saved the energy.Also can reduce valve diameter simultaneously, thereby alleviate valve weight, economical with materials, particularly heavy caliber solenoid valve, effect is particularly remarkable.
The utlity model has anti-sticking, durable, good seal performance, the energy high-frequency operation is applied to steam and also can works reliably, and therefore, this valve application is wider.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of conventional solenoid valve;
Fig. 2 is a structural representation of the present utility model.
Fig. 2 has provided an embodiment of the present utility model.Solenoid valve of the present utility model mainly is made up of main valve body (1), main valve lid (19), main valve plug (2), main valve plug return spring (3), spring guard bar (4), guide valve core (5), guide valve core centering return spring (6), electromagnetic coil (7), magnetic shield (8), buting iron (9), coil case (10) etc., be characterized in around the top of main valve plug (2), having a main valve annular groove (15), can install one or multi-channel main valve ring (16) according to the design needs in the groove with inclined-plane interface; Top center at main valve plug has an internal point (18), the hollow centering bar (20) that stretches out on this hole and the valve gap (19) is nested, in the hole of internal point (18) and hollow centering bar (20), main valve plug return spring (3) is set, one spring guard bar (4) is set in the spring, prevent spring crooked in moving up and down, guaranteed the centering effect of valve body.Primary seal head (17) on the main valve plug is designed to taper, makes main valve plug and exit seal seat sealability better.This self contering cone-shaped seal structure of main valve plug has played the effect every slag, anti-sticking, centering, sealing.Have a pilot valve annular groove (11) around the bottom of its described guide valve core (5), the pilot valve ring (12) that has the inclined-plane interface together is housed in the groove, the center of guide valve core has guide valve core hole (14), the lower central of buting iron (9) has a buting iron hole (25), guide valve core return spring (6) is arranged in guide valve core hole (14) and buting iron hole (25), makes guide valve core play the effect of centering return.Sealing head (13) on the guide valve core (5) is designed to taper, makes seal action better.
The utility model is owing to be equiped with one or multi-channel main valve ring in the main valve annular groove on main valve plug top, and main valve ring is the inclined-plane opening, so no matter fluid temperature (F.T.) just changes the thermal expansion shrinkage of caused valve body and main valve plug, main valve ring can fit with valve body all the time, therefore, the design of gap between main valve plug and the valve body with respect to routine can be increased a lot, be always contactless state.Simultaneously owing to be that main valve ring contacts with valve body, can not cause the phenomenon of valve cisco unity malfunction because of main valve plug and valve body excesssive gap.So the utility model can stand fierce variation of the high low temperature of fluid and high frequency action.
Solenoid valve of the present utility model is highly done the exit seal seat (21) on the valve body very low, generally design below the inlet tube center line, can make unlikely being obstructed of fluid center flow velocity like this,, reach the purpose of energy saving to reduce the loss of pressure head of fluid.
