Description
Technical field
The utility model relates to a kind of pressure unit that has the bellows balance media, relates in particular to a kind of Balancing type full-sealing magnetically-actuated break valve of bellows that relies on magneto drive to block or connect pipeline medium stream.
Background technique
The magneto drive full-sealing valve is a kind of novel product that grows up in valve products in recent years, it is made up of the magnetic driving equipment that valve body part of making according to NBS and permanent magnet constitute, and this valve is realized blocking or connecting of valve by the flexibility contact of actuator and the soft transmission of torque.But such valve is when closing or open, and upstream and downstream pressure acts on respectively on the spool valve rod, and the size of the power that is provided by magnetic force mechanism has a long way to go.When closing because upstream and downstream pressure medium difference Δ P
1Direction opposite with the spool movement direction, the therefore power F that provides by magnetic force mechanism
2Just very big; Medium static pressure P then during unlatching
1Direction identical with the spool movement direction, therefore the power that is provided by magnetic force mechanism will be very little, and this has just caused the wasting of resources of magnetic force mechanism, when such valve applications in heavy caliber or high-pressure environment following time, this phenomenon is just more obvious, thereby has limited the application area of such valve.
Summary of the invention
The purpose of this utility model is to provide a kind of Balancing type full-sealing magnetically-actuated break valve of bellows at defective of the prior art, thereby has overcome the problem that background technique exists effectively.
The technological scheme that its technical problem that solves the utility model adopts is: described a kind of Balancing type full-sealing magnetically-actuated break valve of bellows, valve seat 2 and spool 3 are arranged in the valve body 1, one end of valve rod 6 is connected with spool 3, and the other end of valve rod 6 is connected with magnetic driving equipment; Be characterized on described valve rod 6, being provided with PRESSURE PIPE 4, the outside of valve rod 6 and PRESSURE PIPE 4 corresponding positions are provided with bellows 5, fixedly connected with valve rod 6 in bellows 5 bottoms, bellows 5 tops compress by guide plate 7, guide plate 7 is fixedly mounted on the valve body 1 by the separation sleeve 12 on bolt and the described magnetic driving equipment, be provided with filler 8 in the corresponding endoporus of guide plate 7 and valve rod 6, filler 8 compresses by Gland 9.
Described Balancing type full-sealing magnetically-actuated break valve of bellows, top at valve is a magneto drive mechanism, its driving link is flexible the contact with driven member, the movable sealing structure of valve rod and valve body has been become static seal structure, realized hermetically sealed, bottom at it is connected with spool by valve rod, and the end in that valve rod is connected with spool has PRESSURE PIPE on the valve rod.Bellows is equipped with at middle part at valve rod, and an end of PRESSURE PIPE leads to bellows, and bellows becomes single force output to the static pressure of medium, when valve is in closed condition, and medium static pressure P
1Be delivered to bellows by PRESSURE PIPE, bellows elongates or shortens accordingly, and directed force F 1 affacts on the spool by valve rod, thereby has balanced medium static pressure P
1To the effect of spool, magneto drive mechanism only need provide seal pressure power, then only needs overcome friction during unlatching.When the needs throttle down, the pressure medium of upstream is delivered to bellows one side by PRESSURE PIPE, and the pressure in downstream affacts the bellows opposite side, and bellows is at upstream and downstream pressure difference Δ P
1Effect under elongate or shorten accordingly, be delivered on the valve rod with the form of single force, thereby overcome the upstream and downstream pressure difference, magnetic force mechanism only need overcome the frictional force when closing.
The utility model is compared with background technique, the useful effect that has is: described a kind of Balancing type full-sealing magnetically-actuated break valve of bellows, it has not only realized the hermetically sealed of magneto drive and structure, and adopt bellows to balance pressure medium, eliminated the influence that pressure medium moves spool, thereby make such valve when closing or open, the size of the power that is provided by magnetic force mechanism is equal substantially.Simultaneously the hermetically sealed valve of bellows pressure equaliser and magneto drive has been carried out organic the combination, provide prerequisite, enlarged the using scope of the hermetically sealed valve of magneto drive for further optimizing magneto drive mechanism.
