Abstract
The utility model relates to a cut-off mechanism of an electromagnetic valve. A cone valve flap is connected with the lower end of a valve rod. The cone valve flap has a two-stage convex shoulder and a conical surface as the cylindrical surface of a big end. A conical surface sealed spring is connected between a small convex shoulder and a valve cap. An annular flat valve flap is sheathed coaxially on the big convex shoulder. A flat surface sealed spring is connected between the flat valve flap and the valve cap. A sealed ring is arranged between the flat valve flap and the conical valve flap. The valve seat has a conical surface fitting with the conical valve flap, and a flat surface fitting with the flat valve flap. An annular sealed pad is arranged between the flat valve flap and the valve seat. An O-shaped sealed ring is arranged between the conical valve flap and the valve seat. The double-layer seals of a flat seal and a conical seal are formed. The utility model improves the seal performance of the electromagnetic valve, and the service life is extended. The utility model is suitable for gas controlling system of low pressure.
Description
The utility model relates to the current breaking mechanism of a kind of current breaking mechanism of solenoid valve, particularly straight-through electromagnetic valve.
Solenoid valve is an electric actuator commonly used in the fluid automatic control system.The current breaking mechanism of existing solenoid valve comprises valve body, valve seat, flap, valve rod, valve gap, Sealing and elastic element.The annular flap is connected with valve rod, makes elastic element by spring, flap is risen or compresses, by the sealing of the Gask-O-Seal between valve body and the flap.In the ordinary course of things, the operating pressure differential of existing solenoid valve is very high, during shutoff, can utilize the pressure of working medium to increase sealability.But in gas burning system, because gas ductwork pressure is very low, the solenoid valve operating pressure differential is very little, and the sealability of general solenoid valve can not satisfy the low-pressure fuel gas robot control system(RCS) and use needs, and its life-span does not reach the industry standard set quota yet.
The purpose of this utility model provides a kind of current breaking mechanism of solenoid valve, improves Sealing, forms two-layer sealing, makes it also can not have sealing reliably by working medium pressure, and the performance of long service life is to be applicable to the needs of gas autocontrol system.
The technical solution of the utility model is:
The current breaking mechanism of solenoid valve, comprise valve body, valve seat, flap, valve rod, valve gap, Sealing and elastic element, it is characterized in that, one of the coaxial connection in valve rod lower end is up-small and down-big, and two-stage convex shoulder, big newel post face are arranged is the cylindrical cone valve lobe of the conical surface, between little convex shoulder and valve gap, be connected a conical surface seal spring with valve rod is coaxial; Coaxial socket annular flat flap on big convex shoulder is between flat valve lobe and valve gap, with the coaxial plane sealing spring that is connected of valve rod; Be provided with O-ring seals between flat valve lobe and the cone valve lobe; The neck inboard of ring-shaped valve seats is the conical surface, and the plane is arranged at top, cooperates with cone valve lobe peace flap respectively, between flat valve lobe and the valve seat Gask-O-Seal is arranged, and between cone valve lobe and the valve seat O-ring seals is arranged.
Valve seat and valve body are one or split.
Between valve rod and the cone valve lobe is universal hinging.
The material of sealing gasket and seal ring is rubber, engineering plastics or is the composite material of major ingredient with rubber, engineering plastics respectively.
Working procedure of the present utility model is:
When power connection, valve rod 7 is upwards mentioned, and drives coupled cone valve lobe 11 peaceful flaps 6 and moves up, and makes solenoid valve be in opening state, and gas enters from the inlet on valve body 1 right side, and the valve seat 2 of flowing through flows out through the outlet in valve body left side again.When power supply disconnects, the spring force of plane sealing spring 8 and conical surface seal spring 9 forces flat valve lobe 5 and cone valve lobe 11 to move down, make on sealing gasket 3 and the cone valve lobe 11 on the flat valve lobe 6 O-ring seals 12 respectively with valve seat 2 on annular sealing surface closely contact with conical seal (contact) face, make solenoid valve be in off state, stop gas to pass through.
The utility model has the advantages that: adopt spring masterpiece sealing force fully, increase taper seal, form plain seal and awl sealing double-layer seal; Select the Sealing of suitable material and hardness for use, the sealability of solenoid valve and working life are improved greatly.The 4th detection institute carries out the sealability test according to standard ZBN16002-86 " industrial process control system solenoid valve general technical specifications " through Beijing's quality supervision of construction engineering inspection point, and after 470,000 life tests, leakage rate still is zero.Be applicable to various fluid automatic control systems, particularly low-pressure fuel gas automatic control system.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the current breaking mechanism of solenoid valve, comprise valve body 1, valve seat 2, flap, valve rod 7, valve gap 5, Sealing and elastic element, one of the coaxial connection in valve rod 7 lower ends is up-small and down-big, and two-stage convex shoulder, big newel post face are arranged is the cylindrical cone valve lobe 11 of the conical surface, between little convex shoulder and valve gap 5, be connected a conical surface seal spring 9 with valve rod 7 is coaxial; Coaxial socket annular flat flap 6 on big convex shoulder is between flat valve lobe 6 and valve gap 5, with the valve rod 7 coaxial plane sealing springs 8 that are connected; Be provided with O-ring seals 10 between flat valve lobe 6 and the cone valve lobe 11; The neck inboard of ring-shaped valve seats 2 is conical surfaces, and the plane is arranged at top, cooperates with cone valve lobe 11 peaceful flaps 6 respectively, between flat valve lobe 5 and the valve seat 2 Gask-O-Seal 3 is arranged, and between cone valve lobe 11 and the valve seat 2 O-ring seals 12 is arranged.Valve seat 2 is made of one or separate form with valve body 1 with valve body 1 and valve gap 5, when valve gap 5 and valve body 1 split, establishes seal ring 4 between the two.Between valve rod 7 and the cone valve lobe 11 is universal hinging.The material of sealing gasket 3 and seal ring 10,12 is rubber, engineering plastics or is the composite material of major ingredient with rubber, engineering plastics respectively that when its material was rubber, hardness was 65 ± 5.
