fig. 2 is a schematic view illustrating a structure of an anti-lock fluid flow control valve according to the present invention when an opening degree is closed.
[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
Referring to fig. 1 and 2, an anti-lock fluid flow control valve according to the present invention includes a fixed valve body 1, a movable valve body 2, a guide 3, a guide rod 4 and a spring 5, wherein an input channel 6 and an output channel 7 are respectively formed on an outer circumferential surface and a front end of the fixed valve body 1, the input channel 6 is symmetrically disposed along an axis of the fixed valve body 1, and a fluid medium enters from the input channel 6 and then is output from the output channel 7.
The guide device 3 is fixed on the other end of the fixed valve body 1 opposite to the output channel 7, one end of the guide rod 4 is sleeved with the spring 5 and extends into the movable valve body 2, the movable valve body 2 and the guide rod 4 extend into the guide device 3, the guide rod 4 and the guide device 3 are connected through screw transmission, the movable valve body 2 is located inside the fixed valve body 1, and the guide rod 4 extends to the outside of the guide device 3, so that the guide rod 4 is twisted to realize the movement along the axial direction, and under the action of the spring 5, the movable valve body 2 is pushed to move forwards and backwards to control the movable valve body 2 to be close to the output channel 7 to change the opening size, as shown in fig. 2, when the movable valve body 2 blocks the output channel 7, the spring 5 is in a compressed state, so that the spring 5 gives a reaction force to the guide rod 4 in the axial direction, the guide rod 4 can easily break away from the output channel 7 after slightly twisting the guide rod 4 under the reaction force, so that the phenomenon that the movable valve body 2 is easily locked after blocking the output channel 7 is avoided, the control is more labor-saving and convenient, the damage probability is reduced, and the maintenance cost is saved.
It can be understood that, the guide rod 4 is keeping away from the output channel 7 in-process, the aperture of valve is crescent, and the output flow of fluid medium is also along with increasing, and the guide rod 4 is reverse to keep away from the in-process of moving valve body 2, in order to carry out the position to the guide rod 4 and prescribe a limit to, be close to screw thread department cover on the guide rod 4 and be equipped with stop nut 8, and under stop nut 8's spacing, guide rod 4 stop motion, the valve aperture at this moment is the biggest, and the flow reaches the maximum value, can see that, also can play the maximum value that changes the aperture through specification or the number of selecting stop nut 8.
The movable valve body 2 comprises a valve head 9, the outer side of the valve head 9 forms a taper of 2-160 degrees, and the front end of the valve head is a first arc-shaped surface 10.
In detail, the output channel 7 is a second arc-shaped surface 11 and a third arc-shaped surface 12 which are gradually expanded from the inside to the outside of the fixed valve body 1, the first arc-shaped surface 10, the second arc-shaped surface 11 and the third arc-shaped surface 12 are spherical surfaces or ellipsoidal surfaces, one side in the output channel 7 is small, a large pressure is generated inside to press the fluid medium out of the fixed valve body, the fluidity is enhanced, and the valve head 9 has a taper, so that the design aims to facilitate the shunting when the movable valve body 2 moves and reduce the resistance, when the valve head 9 is in contact with the output channel 7, the opening degree is completely closed, and the fluid medium stops being output.
Finally, the stiffness of the spring 5 is between 0.1N and 1N, the outer diameter of the spring 5 is between 2 mm and 10mm, the larger the outer diameter or the greater the stiffness of the spring 5 is, the larger the elastic force generated by the spring 5 is, the better the fluid medium is for a control valve with a larger size or a fluid medium with a larger Reynolds coefficient, the higher the viscosity of the fluid medium with a larger Reynolds coefficient is, and the poorer the fluidity is, so that a larger acting force needs to be applied to the guide rod 4, thereby obtaining more labor-saving and simple control.
The invention has the advantages that:
this control valve rotates the guide bar and produces the displacement along its axial when using, and drive the movable valve body and produce axial displacement under the effect of spring, the movable valve body takes place the displacement and output channel has formed different valve aperture sizes, change with this control fluid medium's output flow, when the movable valve body plugs up output channel on the extreme end, the spring is in compression state, the spring gives the elasticity effort all the time in the guide bar axis direction, when giving a very little reverse moment of torsion of guide bar, can easily break away from output channel and increase the aperture with the movable valve body, the defect of similar tradition locking has been avoided, make more convenient to use, the safety in utilization of maintenance control valve simultaneously.
The spring with proper rigidity is flexibly selected according to the size of the control valve and the property of the fluid medium, the reaction force of the spring to the guide rod is reasonably controlled, the rotation control of the guide rod is more convenient to use, and the universality is improved.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
