Fig. 2 is the structural representation of the direct-acting type electromagnetism modulating valve of band locating stud of the present invention.
Embodiment
The direct-acting type electromagnetism modulating valve of band locating stud of the present invention, its preferable embodiment is as shown in Figure 2, comprises valve port 2; Valve port 2 places are provided with spool 3, spring 4, and the top of spool 3 is connected with electromagnetic control device, and said electromagnetic control device comprises coil 5; Top in the coil 5 core holes is provided with magnet case 6, and the bottom is provided with armature 7, and the top of said spool 3 and armature 7 link together; The bottom of said magnet case 6 is provided with locating stud 14, and the top of said armature 7 is provided with corresponding positioning pin hole; Perhaps, the top of said armature 7 is provided with locating stud 14, and the bottom of said magnet case 6 is provided with corresponding positioning pin hole.
Through the cooperation of locating stud 14 with corresponding positioning pin hole, when armature 7 is moved up and down, avoid swing in the core hole of coil 5, improve the control accuracy and the performance of valve control.
Can be provided with guide pin bushing 16 in the described positioning pin hole, said locating stud 14 is inserted in the said guide pin bushing 16.Said guide pin bushing 16 is special high-abrasive material, and such as being quartz material, said locating stud 14 can be stainless steel material.Guide pin bushing 16 can be pressed in the said positioning pin hole through gland 15.Use special high-abrasive material can improve steering capability and working life between locating stud and the positioning pin hole as guide pin bushing.
Another one inventive point of the present invention is:
As shown in Figure 2, said coil 5 is provided with shell 11, and the bottom of said shell 11 is through being threaded in the said valve seat 1, and is provided with lower compression nut 17 between the bottom of said valve seat 1 and said shell 11;
The top of said shell 11 is provided with loam cake 13, and said magnet case 6 is threaded with said loam cake 13, and is provided with gland nut 12 between said magnet case 6 and the said loam cake 13.
Can be threaded between the top of said shell 11 and the said loam cake 13.
Adjustment principle of the present invention is: the bottom of the shell 11 of coil 5 is through being threaded in the valve seat 1, and is provided with lower compression nut 17 between the bottom of valve seat 1 and shell 11.When needs are adjusted the pretightening force of spring 4, lower compression nut 17 is unclamped, after the screw-in degree of adjustment shell 11 in valve seat 1, tighten lower compression nut 17 and get final product.Though can influence the size in the gap between armature 7 and the magnet case 6 after this adjustment, can not influence the control performance and the precision of valve, main cause is the gap length that in operating procedure subsequently, can regulate separately between armature 7 and the magnet case 6.
When needs are regulated the gap between armature 7 and the magnet case 6, will go up gland nut 12 and unclamp, the screw-in degree between adjustment magnet case 6 and the loam cake 13 compresses gland nut 12 afterwards and gets final product.Can not influence the size of the pretightening force of spring 4 after this adjustment.
As shown in Figure 1, direct-acting type electromagnetism modulating valve of the prior art, magnet case 6 is fixedly connected with the threaded connector 9 of bottom through connecting sleeve 8, and threaded connector 9 is screwed on the valve seat 1.Afterwards, coil 5 is enclosed within the outside of magnet case 6 and connecting sleeve 8 and is pressed on the valve seat 1, and the top of magnet case 6 is fastening through nut 10.According to designing requirement, there is certain clearance between armature 7 and the magnet case 6.The shortcoming of this valve is: when needs are adjusted the pretightening force of spring 4, at first to unclamp nut 10, and then the screw-in degree of adjustment threaded connector 9 in valve seat 1, again that nut 10 is fastening afterwards.Can influence the gap length between armature 7 and the magnet case 6 after this adjustment; Because magnet case 6 threaded connector 9 through connecting sleeve 8 and bottom is for being fixedly connected; Magnet case 6 can only be with threaded connector 9 motions; So can not continue to regulate the gap length between armature 7 and the magnet case 6 separately, thereby influence the control accuracy and the performance of valve.
Among the present invention, the gap between armature 7 and the magnet case 6 and the pretightening force of spring 4 are separated adjustment and be independent of each other, and be simple to operate, can not influence the control accuracy and the performance of valve.And the pretightening force of the gap between armature 7 and the magnet case 6 and reed 4 can not separate regulation in the original structure.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
