Abstract
The invention provides a magnetic force driving mechanism for a valve. The mechanism comprises a valve rod, wherein the valve rod is supported in a left-end disc through a bearing; the left-end disc is connected with a right-end disc through a connecting sleeve; an outer magnetic cylinder body which is located inside the connecting sleeve is supported on the right-end disc through a bearing; the inside of the outer magnetic cylinder body is provided with an inner rotor which is installed on the valve rod; an isolation hook which is fixedly connected with the left-end disk is arranged between the inner rotor and the outer magnetic cylinder body; a seal pad is arranged between the isolation hook and the left-end disc; inner magnetic blocks are inlaid on the circumferential surface of the outside of the inner rotor; and outer magnetic blocks matched with the inner magnetic blocks are inlaid on the circumferential surface of the inside of the outer magnetic cylinder body. When the magnetic force driving mechanism is used, the valve rod is connected with the valve core of the valve; the left-end disc is fixedly connected with a mounting seat arranged on a tank body in a system; the inner rotor located on the end head of the valve rod is covered in the isolation hook, thus static seal is achieved; and when the outer magnetic cylinder body is rotated, the inner rotor rotates under the action of the magnetic blocks, so as to realize non-contact type dynamic transfer and no medium leakage, thus the magnetic force driving mechanism provided by the invention is safe and reliable, maintenance frequency is reduced, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of magneto drive mechanism that is used for valve.
Background technique
At present in commercial production; Particularly employed valve is the motive sealing formula in the operational system of medium such as poisonous, harmful, inflammable, explosive; Be that valve rod rotation place all is to adopt mechanical sealing or material filling type sealing, leakage phenomenon often appears in this sealing configuration in running, need often Sealing to be carried out maintenance process; Not only safety rate is low, but also influence is produced.
Summary of the invention
The purpose of this invention is to provide a kind of non-contact type transferring power, static sealing, safe and reliable, the magneto drive mechanism that is used for valve that need not often to handle Sealing, overcome the deficiency of existing technology.
The magneto drive mechanism that is used for valve of the present invention; Comprise valve rod, in left end disc, left end disc is connected with right end disc through connecting sleeve to valve rod through bearings; On right end disc, the outer magnetic cylinder body that is positioned at the connecting sleeve inboard is arranged through bearings; There is the internal rotor that is installed on the valve rod inboard of magnetic cylinder body outside, is provided with the shielding can that is fixedly connected with left end disc between internal rotor and the outer magnetic cylinder body, establishes sealing gasket between shielding can and the left end disc; On the outer circumference face of internal rotor, be inlaid with interior magnetic patch, be inlaid with the outer magnetic patch that matches with interior magnetic patch on the inside circumference face of magnetic cylinder body outside.
The magneto drive mechanism that is used for valve of the present invention, during use, valve rod links to each other with the spool of valve, and the fitting seat in left end disc and the system on the tank body is fixedly connected; Because the internal rotor of valve rod termination, has been realized static seal by the separation sleeve cover within it, when rotating outer magnetic cylinder body; Internal rotor rotates thereupon under the effect of magnetic patch, non-contact type transferring power, no dielectric leakage; Safe and reliable, need not frequent repair of seal, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is an A-A section enlarged diagram shown in Figure 1.
Embodiment
Like Fig. 1, shown in 2: 9 is valve rod, and in left end disc 6, bolt is connected with left bearing lid 13 on the left end disc 6 through bearings.Left end disc 6 is connected with right end disc 1 through connecting sleeve 4, is bolt between connecting sleeve 4 and left end disc 6 and the right end disc 1 and is connected.On right end disc 1, through bearings the outer magnetic cylinder body 3 that is positioned at connecting sleeve 4 inboards is arranged, the axle head of outer magnetic cylinder body 3 extend out to the outside of right end disc 1, and right end disc 1 is connected with right bearing lid 10 with bolt.The inboard of magnetic cylinder body 3 has key to be connected the internal rotor 5 on the valve rod 9 outside, and valve rod 9 terminations have nut to be used for internal rotor 5 is carried out axial limiting.Be provided with the shielding can 2 that is fixedly connected with left end disc 6 between internal rotor 5 and the outer magnetic cylinder body 3, establish sealing gasket between shielding can 2 and the left end disc 6.Magnetic patch 12 on the outer circumference face of internal rotor 5, being inlaid with is inlaid with the outer magnetic patch 11 that matches with interior magnetic patch 12 on the inside circumference face of magnetic cylinder body 3 outside.
