Abstract

The utility model relates to a magnetic force rotary type valve which is suitable for industrial and civil fluid pipelines. The magnetic force rotary type valve leaves out a valve rod of a traditional valve and a sealing device for a valve rod and thoroughly eliminates outleakage. The utility model mainly comprises a casing, a stator plate, a first-stage rotor plate, a second-stage rotor plate, a flow blocking plate, a rotary shaft, an inner magnetic coil, an outer magnetic coil, a flange plate (or pipe threads) and a circlip. When the pressure of fluid in a pipeline is lower, the second-stage rotor plate and the flow blocking plate can be left out, and the first-stage rotor plate is replaced by a butterfly blind plate. Compared with the traditional valves, the utility model has the advantages of simple structure and manufacturing technique, light weight, small size, low cost and safer operation.

Description

Magnetic force rotary sheet type valve

A kind of magnetic force rotary sheet type valve is applicable to industry, in the civil pipeline various fluids is blocked or Flow-rate adjustment.

Existing valve is broadly divided into four big class, i.e. gate valve, butterfly valve, ball valve and telescoping valves.Because they do not break away from this assembly of valve rod, make valve rod leak-proof structure become the key link of decision valve performance quality, but also be the weakest position of valve products simultaneously, cause the valve rod leak-proof structure form to emerge in an endless stream, process structure is increasingly sophisticated, also more and more high to its material capability requirement, but sealing effect or working life are still unsatisfactory.

The utility model provides a kind of magnetic force rotary sheet type valve, is the penetrability of utilizing magnetic force, saves valve rod assembly and corresponding sealing configuration, fundamentally rooted out the root of valve leakage out of steam system, thereby simplified valve mechanism and manufacturing process, reduced the weight and volume of valve, reduced cost.

Formation of the present utility model comprises housing [1], still [2], one-level moving plate [3], secondary moving plate [4], spoiler [5], rotating shaft [6], interior magnetosphere [7], outer magnetic ring [8], flange plate (or pipe thread) [9], jump ring [10].Still [2] is fixed in the inside of cylindrical shell [1], have the passage of a pair of axisymmetric 90 ° of fan shaped boreholes on it as fluid, pass and be fixed in the central shaft hole of still [2] with the rotating shaft [6] that housing [1] coaxial line is settled, the one end is spoiler [5] fixedly, the other end is the suit one-level moving plate [3] and the secondary moving plate [4] that can rotate around it successively, wherein one-level moving plate [3] be 90 ° of subtended angles butterfly shape (being that angle respectively is that two of 90 ° of symmetric arrangement are fan-shaped) so that at 90 ° of fan-shaped pylones blocking on the position on the still [2], and after rotating 90 ° the through hole on the open still [2].The fan-shaped pylone that has a pair of axisymmetric subtended angle and be 30 ° on one-level moving plate [3] is as the fluid passage.Secondary moving plate [4] is the butterfly shape of 30 ° of subtended angles, so that at the through hole of blocking on the position on the one-level moving plate [3], and is turning over the through hole on the open one-level moving plate [3] after 30 °.Appropriate location on still [2], one-level moving plate [3], secondary moving plate [4] is equipped with meet and discuss (can't illustrate among the figure) and is blocked by one-level moving plate [3] to guarantee 90 ° of through holes on still [2], and after 30 ° of through holes of one-level moving plate [3] are blocked by secondary moving plate [4], rotation secondary moving plate [4] can be opened the through hole on the one-level moving plate [3], then drag one-level moving plate [3] half-twist if continue equidirectional rotation, thereby open the through hole on the still [2] by meeting and discussing on the one-level moving plate [3].During secondary moving plate [4] counterrotating, at first close 30 ° of through holes on the one-level moving plate [3], and meet and discuss by on the one-level moving plate [3] another and to drag one-level moving plate [3] and continue the 90 ° fan-shaped pylones of rotation on Close All still [2] along this direction.Interior magnetosphere [7] upper edge circumference is fixed one group of magnetic steel ingot (radial magnetizing), and whole interior magnetosphere [7] is fixed on the secondary moving plate [4] both coaxial lines; Outer magnetic ring [8] upper edge circumference is fixed one group of magnetic steel ingot (radial magnetizing) and is sleeved on the outside of housing [1].Because the effect of two groups of magnet steel magnetic force, interior magnetosphere [7] and outer magnetic ring [8] automatic centering, rotate outer magnetic ring [8] to certain direction, then because the secondary moving plate [4] that magnetic force drags interior magnetosphere [7] and is connected with it, and then continue to drag one-level moving plate [3] by meeting and discussing on the one-level moving plate [3] and rotate, until the through hole of opening on the still [2]; To drag the rotation of interior magnetosphere [7] and the secondary moving plate [4] that is connected with it during outer magnetic ring [8] counterrotating owing to the effect of magnetic force, and then meet and discuss by on the one-level moving plate [3] another and to continue to drag one-level moving plate [3] and rotate until the through hole of closing on the still [2].The two-stage moving plate being set and installing spoiler [5] additional is in order to reduce the drawing torque of moving plate, and magnetic torque is enough to open or close valve when guaranteeing on moving plate hydrodynamic pressure very big (thereby frictional force and friction torque are also very big between moving plate and still).The flange plate (or pipe thread) [9] of housing [1] both sides is used for whole valve body and is connected with pipeline.Jump ring [10] is used to limit the axial float of the two-stage moving plate in the rotating shaft [6].When hydrodynamic pressure in the pipeline was low, the magnet steel driving moment was enough, thereby can save secondary moving plate [4] and spoiler [5], and the fan-shaped pylone that then no longer has a pair of axisymmetric subtended angle on the one-level moving plate [3] and be 30 ° becomes blind plate.Interior magnetosphere [7] directly is fixed on the one-level moving plate [3].
