Abstract
The utility model relates to an axial-type connecting structure for a valve core position detector and an electromagnetic directional valve. The axial-type connecting structure comprises the electromagnetic directional valve, the valve core position detector, a spring and a cover cap type washer. An induction rod of the valve core position detector is composed of a rod body, a rod neck and a rod head. The cover cap type washer is composed of a cap base, a cap wall and a cap cover. The rod head of the induction rod is attached to the valve core shaft neck end side of the electromagnetic directional valve and inserted into the cover cap type washer. The induction rod is sleeved with a sealing induction sleeve of the valve core position detector, and the sealing induction sleeve of the valve core position detector is screwed to a valve body of the electromagnetic directional valve through external threads of a connector of the valve core position detector. The axial-type connecting structure for the valve core position detector and the electromagnetic directional valve has the advantages that the induction rod of the valve core position detector is connected with a valve core through the cover cap type washer, the action state of the valve core is reliably shown, the structure is compact, installation is convenient, precision is high, friction losses do not exist, service life is long, meanwhile, maintenance is more convenient and easier, and the axial-type connecting structure can be popularized.
Description
Technical field
The utility model relates to a kind of solenoid directional control valve, especially relates to a kind of valve element position detector and solenoid directional control valve axial type linkage structure.
Background technique
By position detector, detecting the switching of spool operating position is accepted by numerous user.In the prior art, the linkage structure of valve element position detector induction rod and electromagnetic switch valve core roughly has the situation of two aspects: the one, and structure is too complicated, the high Difficulty that causes of cost; Another kind is that structure is owed rationally, and the induction rod of position detector is asynchronous with the spool of solenoid directional control valve, is prone to misjudgment phenomenon, once have an accident, will produce serious consequence.Therefore, seek that a kind of cost performance is high, the linkage structure of reliable in action is current problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is valve element position detector and the solenoid directional control valve axial type linkage structure that a kind of simple in structure, easy for installation, reliable in action is provided for prior art deficiency.
The purpose of this utility model is to realize by following measures: a kind of valve element position detector and solenoid directional control valve axial type linkage structure, and it comprises solenoid directional control valve, valve element position detector, it is characterized in that, also has spring, block type washer, described solenoid directional control valve spool axle head is provided with axle journal, the place, axle center of connecting head one end of described valve element position detector is provided with cavity, the outer rim of this end is provided with the outside thread being connected with electromagnetic switch valve body, the induction rod of described valve element position detector is by shaft, bar neck, bar head forms, described block type washer is by cap seat, cap wall, cap forms, place, cap axle center is provided with the through hole corresponding with the bar neck of induction rod, described spool, cavity, induction rod three's shaft axis is overlapping, it is distolateral that described induction club head is fitted in the spool axle journal of solenoid directional control valve, from block type washer is inner, insert, shaft is overhanging outside the through hole of block type washer, rod head end side is fitted in cap dorsal part, bar neck is positioned on the through hole of cap, the sealing induction jacket casing of valve element position detector is on induction rod, and be tightened on electromagnetic switch valve body by the outside thread of valve element position detector connecting head.
The cap wall of described block type washer is provided with through hole.
Compared with prior art, valve element position detector and the solenoid directional control valve axial type linkage structure that the utility model proposes have been adopted, tool has the following advantages: this product is connected by block type washer the induction rod of valve element position detector with spool, reliably spool operating state is showed, there is compact structure, easy for installation, validity is high, without the long feature of abrasion, life-span, also make maintaining more convenient easily, be a propagable product simultaneously.
Accompanying drawing explanation
Fig. 1 is the example structure schematic diagram the utility model proposes.
Fig. 2 is the sectional view of Fig. 1 embodiment solenoid directional control valve and valve element position detector linkage structure.
Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated: Fig. 1～Fig. 2 shows an embodiment of the present utility model.In figure, a kind of valve element position detector and solenoid directional control valve axial type linkage structure, it comprises solenoid directional control valve 1, valve element position detector 2, spring 5, block type washer 6, described solenoid directional control valve 1 spool 11 axle heads are provided with axle journal, the place, axle center of connecting head 21 one end of described valve element position detector 2 is provided with cavity, the outer rim of this end is provided with the outside thread being connected with solenoid directional control valve 1 valve body, the induction rod 22 of described valve element position detector 2 is by shaft, bar neck, bar head forms, described block type washer 6 is by cap seat, cap wall, cap forms, place, cap axle center is provided with the through hole corresponding with the bar neck of induction rod 22, described spool, cavity, induction rod three's shaft axis is overlapping, spool 11 axle journals that described induction rod 22 bar heads are fitted in solenoid directional control valve 1 are distolateral, from block type washer 6 is inner, insert, shaft is overhanging outside the through hole of block type washer 6, rod head end side is fitted in cap dorsal part, bar neck is positioned on the through hole of cap, the sealing induction sleeve 23 of valve element position detector is enclosed within on induction rod 22, and be tightened on solenoid directional control valve 1 valve body by the outside thread of valve element position detector 2 connecting heads 23.In this structure, when moving, spool drive induction rod in company with action by block type washer, the relative position of the induction sleeve of induction rod and valve element position detector changes, the machinery action of spool is converted to electrical signal, by the electrical signal of output, confirm whether the movement of spool puts in place, or provide the signal of reporting to the police or allowing normal operation.When valve core reset, by the effect of spring, block type washer drives induction rod and spool together to reset.
The utility model is further taked following measure: the cap wall of described block type washer 6 is provided with through hole 7.The setting of this through hole 7, order part oil enter cap type washer cap wall inwall, lubricating of induction rod, spool and cap type washer inwall is provided.
The embodiment who provides above does not form restriction of the present utility model, and in related domain, those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain.
