Abstract
The utility model relates to a valve opening and closing operating mechanism, which is composed of a crossbar combination magnetic circuit type barrel-shaped permanent magnet magnetic coupler. The part of an operating handwheel of a traditional valve is provided with the permanent magnet magnetic coupler which is composed of coaxial inner and outer magnetic coils and an isolating barrel which is arranged between the inner and the outer magnetic coils. The inner part of the valve and the inner magnetic coil of the coupler are completely sealed outwards by the isolating barrel. The outer magnetic coil of the coupler is rotated, and the inner magnetic coil of the cupler follows the movement under the action of magnetic field force, and therefore, no outleakage opening and closing of the valve is realized. The operating mechanism is characterized in that magnetic blocks in the inner and the outer magnetic coils are arranged in the mode of circumferential direction subarea and axial direction subsection. The magnetic circuit can be used fully, and therefore, the dimension of the operating mechanism is a little smaller, the force application is much bigger, and the cost is not increased. The valve which adopts the operating mechanism is especially suitable for inflammable, explosive and toxic pipeline systems.
Description
The utility model relates to the opening and closing operations mechanism of valve.Use and to unite the keying operation that magnetic circuit formula tubular permanent magnetism magnetic coupling apparatus carries out valve in length and breadth, realize that valve does not have to leak outside.
The valve opening and closing operating device (hereinafter claiming former mechanism) that the permanent magnetism magnetic coupling apparatus of prior art drives uses cartridge type hydromagnetic magnetic coupling apparatus to carry out the keying operation of valve.Fig. 2 is a kind of of former mechanism.Wherein 21 is cylindric outer magnetic ring, and 23 is cylindric interior magnetosphere.The 22 beaker shape shielding cans of making for nonferromagnetic material.Shielding can is like the inversion of beaker, its peristome by seal ring 24 and valve body 25 mat bolts tight; Interior magnetosphere is within shielding can, and outer magnetic ring is outside shielding can, and 21,22,23 form typical cartridge type permanent magnetism magnetic coupling apparatus.When making outer magnetic ring 21 rotations by turn handwheel 26, close by the lotus root between interior outer magnetic ring magnetic field, the interior magnetosphere 23 in the shielding can is followed rotation, does corresponding motion thereby drive valve rod 27, makes flap 28 promote or fall, and realizes the opening and closing operations of valve.Because shielding can has been realized to external world totally-enclosed of valve internal, so valve does not leak outside fully.Its magnetic circuit of cartridge type permanent magnetism magnetic coupling apparatus here is closed in the transverse section of magnetic coupling apparatus singlely, if ignore the End effect of magnetic circuit, then the flux distribution on all transverse section of magnetic coupling apparatus all is similar, with one 4 utmost point permanent magnetism magnetic coupling apparatus is example, and the magnetic flux distribution diagram on its transverse section is as Fig. 3.Wherein 31 is outer magnetic ring, and 32 is interior magnetosphere, and 34 is the magnetic line of force.Find out from figure:
1. the utilization of magnetic circuit is very insufficient, and is close very low with the position magnetic shown in the netting twine in Fig. 3;
Since magnetic circuit in the close distribution of magnetic very uneven, think that the used permanent-magnet material quantity of magnetic torsion moment that reaches required will increase;
3. magnetic circuit utilizes insufficiently, and the permanent-magnet material consumption increases, and all causes device volume to strengthen and the cost increase.
The purpose of this utility model is the above-mentioned shortcoming at former mechanism, and a kind of technology that can improve the magnetic circuit utilization ratio is provided, and is littler to produce volume, the valve magnetic torsion opening/closing mechanism that price is lower.
The technical solution of the utility model is to unite magnetic circuit formula tubular permanent magnetism magnetic coupling apparatus in length and breadth in the rotation hand wheel location arrangements of conventional valves.The magnetic coupling apparatus comprises that the inside and outside permanent magnetism lotus root of coaxial line closes portion and isolation part, it is characterized in that described inside and outside permanent magnetism lotus root is closed and the isolation part is the inside and outside magnetosphere 14,12 and the cage ring 13 of core structure; Described inside and outside magnetosphere 14,12 each by irony cylinder 18,18 ' and irony cylinder 18 to external cylindrical surface and irony cylinder 18 ' circlewise permanent magnets 19,19 ' institute on inner cylindrical surface constitute; Described permanent magnets becomes the alternate polarity of N, S along irony cylinder circumferential magnetization, and direct-axis is to then being truncated into isometric two sections, and polarity is magnetized on the contrary; Described isolating cylinder is the non iron cylinder, the both sides of the permanent magnets office tube of inside and outside magnetosphere, and magnetic patch faces one another across isolating cylinder 14; The valve body 15 of isolating cylinder and valve is tightly connected, and interior magnetosphere is encapsulated in the valve inner space; The valve rod 16 of interior magnetosphere center and opening/shutting valve links.The outer magnetic ring irony cylinder outside can be welded with steel ring 11 and play the operation handwheel, when turn steel ring 11, rotation is followed in the magnetic field force induced effect of interior magnetosphere, valve rod 16 in drive is connected on the magnetosphere rotates, valve rod just makes the flap 17 that its lower end closed by the screw thread lotus root or rises or fall, the nothing that the realizes valve switching that leaks outside.
The utility model that adds up to has following characteristics by uniting the valve opening and closing operating device that magnetic circuit formula tubular permanent magnetism magnetic coupling apparatus constitutes in length and breadth:
1. unite magnetic circuit formula tubular permanent magnetism magnetic coupling apparatus in length and breadth in the location arrangements of conventional valve dress rotation hand wheel.Be welded with steel ring on the irony cylinder of the one side magnetosphere (this place is outer magnetic ring) of this magnetic coupling apparatus and play the operation handwheel.Whole operation mechanism has kept the topology layout and the profile characteristic of conventional valves on layout and profile.
2. the arrangement principle of uniting the permanent magnets on the outer magnetic ring in the magnetic circuit formula tubular permanent magnetism magnetic coupling apparatus in length and breadth can be classified as circumferential subregion, eight words of axial segmentation, be that magnetic patch is along circumferentially being magnetized into the opposed polarity district by the alternate mode of N, S, then cut in two vertically, polarity is opposite.Like this, just have simultaneously along the magnetic flux of circumferential and axial in the irony cylinder of inside and outside magnetosphere and pass through, therefore magnetic circuit obtains to make full use of, thereby makes whole magnetic coupling apparatus volume littler, and it is bigger to exert oneself.
