Abstract
The utility model provides an adjustable magnetic entering right angle one-way valve, which is mainly characterized in that the upper end of a valve core of the one-way valve is provided with repellent two parts of permanent magnet; repulsion force of permanent magnet is utilized to enable the valve core and a valve seat to be hermetic. When the system pressure is greater than the repulsion force, the valve is opened; when the system pressure is smaller than the repulsion force, the valve is closed. Only a control nut is screwed, making the magnetic gap between the two repellent two parts of permanent magnet be increased or be decreased, and the pressure of the valve core and the valve seat can be adjusted. The utility model can be used as a one-way valve and a back pressure valve in hydraulic transmission. The utility model has the advantages of small size and rapid response speed, and is suitable to be used in a complex automatic control system.
Description
The utility model belongs to the one-way valve class in the hydraulic transmission.
One-way valve is used valve as control in hydraulic transmission, in recent years, along with the raising of automatization level, wish that the speed of response of valve wants fast, and component size is little, is convenient to integrated.But one-way valve commonly used at present is general owing to controlling the unlatching of spool with spring force or closing, and not only reaction is slow, and volume is big.
The purpose of this utility model provides a kind of speed of response fast, the adjustable magnetic angle one-way valve that volume is little.
The purpose of this utility model is achieved in that in the upper end of one-way valve spool, and two-part permanent magnet that repels each other is housed, and utilizes the repulsion of permanent magnet to make spool and valve seat closure, and when system pressure during greater than repulsion, valve is opened, and valve cuts out during less than magnetic force.Transfer the pressure of spool and valve seat, only need turn the conciliation nut, make the magnetic gap increase of the two-part permanent magnet that repels each other or reduce.

Below in conjunction with description of drawings concrete structure of the present utility model;
The filler opening (A mouth) of the housing (2) of the utility model (Fig. 1), be fixed with the valve seat (3) of annular, and seal with round section joint ring, the sealing surface of the spool of column (4) lower end and valve seat is conical, the upper end is fixed with down permanent magnet (5) with binder, the outer ring of spool is with adjusts nut (7), there are round section joint ring and housing (2) sealing in the lower end, top has screw thread to be connected with housing (2), turns screw thread, and nut is moved up and down, with the relative part of permanent magnet (5), be bonded with magnet case (8), and be bonded with thereon and following permanent magnet polarity last permanent magnet (6) in opposite directions, permanent magnet repels each other up and down, make spool (4) and valve seat (3) sealing, adjust nut (7), can adjust permanent magnet (5 up and down, 6) magnetic gap, the cracking pressure of change valve.Other elements of the lower end of housing and system carry out plate and are connected, with round section joint ring (1) sealing.
Housing of the present utility model (2) and nut (7) adopt nonmagnetic substance.
The permanent magnet that the utility model adopts, that effect is splendid is neodymium-iron-boron (Nd-Fe-B).The permanent magnet shape is overlooked figure and is seen it is monoblock annulus (Fig. 3, Fig. 5) from the upper end, magnetizing direction is that axially magnet case also is annulus (Fig. 4, Fig. 6), and the shape of cross section of permanent magnet and magnet case can be square, rectangular and trapezoidal.
Working principle of the present utility model is, when A, B mouth all do not have the fluid inflow or flow out, because two block permanent magnet homopolarities repulsion is in opposite directions closed valve, when having fluid, the A mouth flows into, hydrodynamic pressure overcomes magnetic force and opens spool, and along with increasing of hydrodynamic pressure, valve can reach maximum opening.When maximum opening, it is big that the repulsion of permanent magnet becomes, and makes the aperture of valve keep certain; When hydrodynamic pressure reduces or system when quitting work, rely on magnetic force, valve cuts out automatically.
Great advantage of the present utility model is for having reduced the pressure loss (Fig. 2), coordinate F
SO ' and curve I have reflected cylindroid helicalcoil compression spring compressive force F
5And the relation between the decrement d, coordinate FmOgap and curve II have reflected the relation of magnetic force and magnetic gap.B is a closing point, and A is specified aperture point.At specified aperture point A, magnetic force is less than the compressive force of spring, so the pressure loss reduces, the response of valve actuation attitude improves.
The utility model is done the back pressure valve time spent, does not need to change harder spring, only needs precession to adjust nut (7), reduces magnetic gap.
The utility model is simple and reasonable for structure, cost is low, can be used as in the hydraulic transmission adjustable one-way valve and back pressure valve use, because volume is little, speed of response is fast, so be applicable to comparatively complicated automation control system.
