Abstract
The utility model discloses a spring magnetron superposition-type gas motor valve alnico displacement box, which is mainly composed of a tabulate body which integrates into a multi-function gauge plate structure. Technical characteristics rest with: an overall structure with a stop circle arranged at the outside wall of a port of a cup body, a vice alnico displacement lead rail is arranged on the inner wall of the cup body, a location hole and an alnico stop circle are arranged at the bottom of a lumen, and the outside bottom of the lumen is heave-shaped; the surface of the stop circle is procumbent L-shaped , and the bottom of the stop circle is F-shaped lodging; the F-shaped concave is used as a spring shoe plate, the outside wall of the F-shaped concave is an U-shaped valve cover vice lead rail connecting base. The overall shape of the displacement box is just like a cup with a side ring, and each structure shape from inside and outside has specific function and purpose.
Description
Technical field
The utility model belongs to combustion gas motor valve technology field, relates in particular to a kind of main magnetic steel displacement case of fuel gas motor relief valve.
Background technique
Present a kind of spring magnetic control superposed type fuel gas motor relief valve is (in application on August 10th, 2006 patent of invention, number of patent application 200610029891.9), for realizing the function of full closed electric machine case, stablize the valve operation, the main magnetic steel displacement case is one of critical component, and structure, the shape of main magnetic steel displacement case reasonable in design play an important role to the performance of valve.
Summary of the invention
The purpose of this utility model is that providing a kind of can effectively address the above problem, and guarantees that spring magnetic control superposed type fuel gas motor relief valve is simple in structure, goes slick, stable performance.
For achieving the above object, the technical solution adopted in the utility model is, a kind of spring magnetic control superposed type fuel gas motor valve main magnetic steel displacement case overall structure is shaped as the cup of a band edge circle, it is characterized in that: a ring circle with concentric is placed in the unitary construction that is lower than the cup port outer wall, the cup inwall is provided with the secondary guide rail of main magnetic steel displacement, intracavity bottom has a positioning hole and main magnet steel to end circle, and outer bottom is convex; Ring circle surface is accumbency L shape, and the bottom is lodging F shape; The indent of F shape is made as spring-support plate, and outer wall is that the secondary guide rail of U type valve cover mechanism connects pedestal.
Main magnetic steel displacement case and full closed electric machine case pedestal link, should install seal arrangement additional, Sealing is installed at ring circle surface accumbency L shape position, not only play sealing effect, and can firmly connect, simultaneously, spool length can reduce the thickness of Sealing again, the height dimension at this position should be when being enough to sealed attachment main magnetic steel displacement case and full closed electric machine case, and the size after Sealing is compressed matches; The secondary guide rail of described main magnetic steel displacement is the projection that is complementary with main magnetic steel displacement guide rail, with the cup axis parallel, is provided with two at least; It is a protruding ring-type that main magnet steel ends circle, its function is: main magnetic steel displacement is to main magnetic steel displacement case bottom, ring-type master's magnet steel ends circle and helps reducing bottom the main magnet steel and the area of contact between main magnetic steel displacement case bottom, reduces static friction coefficient, helps the reverse displacement of main magnet steel; The cup-shaped outer bottom becomes projection, and the base thickness size that secondary magnet steel is installed by its bump sizes and U type valve cover mechanism matches, and reaches the requirement that reduces the valve total height; Spring-support plate is located at recess in the lodging F shape, make itself and main magnetic steel displacement case disjunctor, produce size error when purpose is to exempt mounting spring, dimensional accuracy and pre-pressure of the spring when stabilizing spring is operated in " two magnet steel adsorption site spacings " guarantee that " two magnet steel suction " size is constant; Adopt the interference fit method, after can making the secondary guide rail inwall of U type valve cover mechanism displacement be pressed into ring circle lodging F shape outer wall, both have been closely linked, reach the effect of the secondary guide rail of firm U type valve cover mechanism displacement, the secondary guide rail of this U type valve cover mechanism displacement connects pedestal, simple in structure, easy for installation, with low cost; In ring also uniform clamping bolt perforation around the circle.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, compact structure, the simple structure of main magnetic steel displacement case, shape meet the demand of multinomial function, and, reduce the total height of valve, saved cost, adapted to the demand of market valve miniaturization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structure shape schematic representation of the present utility model.
Embodiment
A kind of spring magnetic control superposed type fuel gas motor valve main magnetic steel displacement case overall structure is shaped as the cup of a band edge circle, it is characterized in that: a ring circle with concentric is placed in the unitary construction that is lower than the cup port outer wall, the cup inwall is provided with the secondary guide rail of main magnetic steel displacement, intracavity bottom has a positioning hole and main magnet steel to end circle, and outer bottom is convex; Ring circle surface is accumbency L shape, and the bottom is lodging F shape; The indent of F shape is made as spring-support plate, and outer wall is that the secondary guide rail of U type valve cover mechanism connects pedestal.
Accompanying drawing is a structure shape schematic representation of the present utility model, present embodiment is as shown in drawings: a ring circle 1 with concentric is placed in the unitary construction that is lower than cup 2 port outer walls, cup inner chamber 4 is main magnetic steel displacement spaces, the cup inwall is provided with the secondary guide rail 3 of main magnetic steel displacement, intracavity bottom is provided with a positioning hole 6 and main magnet steel ends circle 7, for screw-thread drive shaft being installed and being reduced the area of contact of main magnet steel and bottom, outer bottom projection 10 is coincide with secondary magnet steel base thickness, the drop space of ring circle 1 and cup 2, be accumbency L shape 5 for the sealing gasket circle is installed, ring circle 1 bottom is lodging F shape indent spring-support plate 8 is set, outer wall 9 is that the secondary guide rail of U type valve cover mechanism connects pedestal, main magnetic steel displacement case global shape is like the cup of a band edge circle, and each structure shape all has its specific function and purposes from inside to outside.
