Abstract
The utility model relates to a magnetic driving ball valve. A wedge angle is formed between two sealing surfaces in a valve body which has an integral structure. Sealing rings and a sphere are arranged in the valve body. A sealing pair is composed of the outer planes of the two sealing rings and the two sealing wedge surfaces of the valve body, and the other sealing par is composed of the inner conical surfaces of the two sealing rings and the inner surface of the sphere. The lower part of a valve rod which is sheathed with a pressure spring on the outside is inserted in a groove on the upper part of the sphere. The valve rod and an inner magnetic assembly are connected through a flat key, and a sealing conical surface on the valve rod is provided with an upper sealing ring. An isolating sleeve is fixed on a flange in the valve body, and the upper end of an outer magnetism assembly which is sheathed on the upper part of the isolating sleeve is provided with a square table. The utility model has the advantages of no inner leakage and one outer leakage.
Description
The utility model belongs to ball valve design and manufacturing technology field.
Ball valve is simple in structure with it, volume is little, in light weight, advantage such as flow resistance is little, is used widely.Its deficiency is that by manpower or the direct rotation valve rod drive of mechanical force spheroid rotary opening and closing valve, valve rod and valve body are movable sealing structure, are easy to generate outer seepage of medium or leakage.
The purpose of this utility model is at existing ball valve defective structurally, to provide a kind of magnetic drives ball valve.
The utility model is achieved by the following technical solution:
On the basis of existing ball valve, to change and be sealed into static seal, two sealing surfaces are a contract angle in the valve body; Changing elastic seat is hard valve seat, and spring force directly acts on spheroid, indirectly-acting in seal ring, and during opening/shutting valve, strength is used for outer magnetic assembly and passes to interior assembly, finishes the keying of valve.Neither interior leakage of this magnetic drives ball valve do not leak outside yet.
Below in conjunction with accompanying drawing structure shape of the present utility model is done and to be specified.
Accompanying drawing is a structural representation of the present utility model
1-valve body 2-seal ring 3-spheroid 4-plain washer 6-separation sleeve 6-goes up the outer magnetic assembly 9-flat key 10-hexagon nut 11-stud bolt 12-gasket seal 13-valve rod 14-pressure spring of magnetic assembly 8-in the seal ring 7-
The magnetic drives ball valve is formed by valve body, seal ring, spheroid, separation sleeve, interior magnetic assembly, outer magnetic assembly, valve rod and bolt, nut structure.
Valve body 1 is an overall structure, and two sealing surfaces are a contract angle in the valve body, seal ring 2, spheroid 3, two seal rings, 2 outerplanars and one sealing of 1 liang of sealing of valve body contract face formation is housed in the valve body 1 pays; Two seal rings, 2 inner conical surfaces and spheroid 3 surfaces constitute another sealing and pay.Insert in spheroid 3 upper grooves bottom of the valve rod 13 of outside suit pressure spring 14, plain washer 4 is arranged below the pressure spring 14, and spring gives sealing to give the power of carrying.Valve rod 13 is connected by flat key 9 with interior magnetic assembly 7.Pressure spring 14 upwards elastic force makes the sealing cone on the valve rod 13 tightly contact, seal with last seal ring 6 inner conical surfaces; Spring gives tight power with sealing for spheroid 3 to down spring.Separation sleeve 6 is fixed on the middle flange of valve body 1 through stud bolt, nut (10,11).So far, interior magnetic assembly 6, valve rod 13, spheroid 3 and seal ring 2 envelopes are close in valve body 1, realize the valve rod static seal.Outer magnetic assembly 8 is enclosed within separation sleeve 5 tops.There is Yi Fangtai outer magnetic assembly 8 upper ends.
Material of the present utility model can be different different because of fed sheet of a media, can be stainless steel, also can be ferrous metal.Wherein the material of seal ring is that metal or metal frame are inlayed fluoroplastic.
Using method of the present utility model:
This magnetic drives ball valve is connected in the material pipeline, and connecting means is that flange connects, and also can make screwed connection into or is welded to connect.Turn square platform on the outer magnetic assembly with spanner, outer magnetic assembly is rotated, under the effect of magnet steel, the magnetic assembly rotates in driving, and promptly magnetic valve connects valve rod is rotated, and finishes the valve opening and closing action.
The utility model has the advantages that structure advanced person, sealing means are static seal, good seal performance; Safe and reliable, both Leak not and also do not leak outside long service life. Be suitable for most the pipage control of valuable medium and poisonous and harmful medium.
By the explanation of structure shown in the drawings and specification the 5th part, with standard machinery technology process component, assembling Get up to implement the utility model.
