The purpose of this utility model provides a kind of Throttle Valves by Magnetic Field Strength Transmission, and this throttle valve can solve the external leakage problem of throttle valve, and improves the stability of its flow.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Throttle Valves by Magnetic Field Strength Transmission is characterized in that: it comprises valve body, spool, outer magnet, inner magnet, spring and adjusting nut, and described valve body is fixedlyed connected with the inflow port supporting sleeve; Spool is arranged in the valve body and with inner magnet fixedlys connected; The outer magnet suitable with inner magnet is arranged on the valve body; Spring housing is contained on the valve body and is positioned at a side of outer magnet; Adjusting nut is sleeved on the valve body and is positioned at the opposite side of outer magnet; Outer magnet can drive inner magnet under the acting in conjunction of adjusting nut and spring and spool moves axially along valve body together.
In the utility model, can meet the demands for guaranteeing the magnetic field suction between outer magnet and the inner magnet, described outer magnet and inner magnet are made by one group of annular permanent-magnet material.One group of annular permanent-magnet material is made up of at least two permanent magnet magnetic patch.Outer magnet is relative with the inner magnet heteropole, can attract each other under the effect of magnetic force, and the magnetic circuit that outer magnet and inner magnet constitute makes outer magnet when valve body moves axially, and inner magnet can produce in the same way and move.
In the utility model, for guarantee effect on throttle valve difference force Δ p change direction and choke area A change in the opposite direction the inlet/outlet line of valve body and the axis coaxle of spool.
The best method that solves external leakage is taked the effective seal measure exactly, facts have proved, can accomplish to stop fully under the static seal state to leak; And under the motive sealing state, no matter be to adopt which kind of sealing (as packing seal, seal with elastometic washer etc.) owing to exist relative movement between the part, leakage can not be eliminated fully, particularly service time long more, the sealing material wearing and tearing are serious more, leak just big more.The utility model constitutes by screw thread the inflow port supporting sleeve fixedlys connected with valve body, and motive sealing is converted into static seal, for preventing the generation of external leakage phenomenon, is provided with seal ring between valve body and inflow port supporting sleeve, thereby thoroughly solves the external leakage problem.

Five, embodiment
A kind of Throttle Valves by Magnetic Field Strength Transmission described in the utility model comprises valve body 2, spring 3, outer magnet 4, inner magnet 5, adjusting nut 6, spool 7 and seal ring 8.Valve body 2 constitutes by screw thread with inflow port supporting sleeve 1 fixedlys connected the end face seal that seal ring 8 forms between inflow port supporting sleeve 1 and the valve body 2.Spool 7 is arranged in the valve body 2 and with inner magnet 5 fixedlys connected, and can moving axially along valve body 2.Outer magnet 4 is arranged on the valve body 2 and is suitable with inner magnet 5.Spring 3 is sleeved on the valve body 2 and is positioned at a side of outer magnet 4; Adjusting nut 6 is sleeved on the valve body 2 and is positioned at the opposite side of outer magnet 4; Outer magnet 4 can drive inner magnet 5 under the acting in conjunction of adjusting nut 6 and spring 3 and spool 7 moves axially along valve body 2 together.
Adjusting nut 6 cooperates with valve body 2 by screw thread, and can moving axially along valve body 2.Spring 3 is compressed under the acting in conjunction of valve body 2 and adjusting nut 6.Spool 7 middle parts are axial bore, by two apertures at the bottom of the hole spool 7 middle part axial bores are linked to each other with end space, and spool 7 front ends have two triangular grooves.Valve body 2 separates outer magnet 4 and inner magnet 5.
Working procedure of the present utility model is as follows: outer magnet 4 is relative with inner magnet 5 heteropoles, attracts each other under the effect of magnetic force.Because inner magnet 5 is fixedly linked with spool 7, during work on the spool 7 effect two power are arranged: the difference force of magnetic field suction between outer magnet 4 and the inner magnet 5 and flow of fluid generation, the direction of magnetic field suction is opposite with the direction of difference force.When outer magnet 4 was positioned at a certain position, because the acting in conjunction of magnetic force and difference force, inner magnet 5 also was in a certain relative position, this moment spool 7 ends two triangular grooves and valve body 2 on the passage section of valve port formation throttle valve.Rotate adjusting nut 6, make its moving axially along valve body 2.Under the acting in conjunction of spring 3 and adjusting nut 6, outer magnet 4 moves axially along valve body 2, at this moment do to move in the same way by magnetic force drive inner magnet and spool, changed the position of valve port on the relative valve body 2 of spool 7 end triangular grooves, thereby changed the passage section area of throttle valve, reached the effect of regulating flow.
Liquid of the present utility model stream is because inlet/outlet immobilizes, and import is positioned on the inflow port supporting sleeve 1, thereby it is consistent with the flow direction of liquid to act on the direction of the difference force Δ p on the spool 7.If it is big that difference force Δ p becomes, magnetic force on the spool 7 and difference force disequilibrium make spool 7 move to Way out, until reaching new balance.At this moment the throttle valve passage section area of the relative valve body 2 valve ports formation of spool 7 end triangular grooves reduces, and the variation of choke area A and difference force Δ p change in the opposite direction, thereby keeps the stability of flow q.Otherwise, if difference force Δ p diminishes, to moving, the throttle valve passage section area that relative valve body 2 valve ports of spool 7 end triangular grooves constitute increases spool 7 to the importer, the variation of choke area A is still opposite with the change direction of difference force Δ p, thereby keeps the stability of flow q.
