Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the embodiment of the present invention includes a housing 1 , a skeleton 2 , an armature 3 , a left coil 4 , a right coil 5 , a left end cap 6 , a right end cap 7 , a left reed 8 and a right reed 9 .

[0027] Such as figure 2 As shown, the housing 1 is made of electrical pure iron, and the shape is a cylinder. The inner space of the cylinder is divided into a left inner space 1-2 symmetrical to the spacer ring by a spacer ring 1-1 connected with the wall of the cylinder. And the inner space 1-3 on the right side, the spacer ring 1-1 has a central circular hole;

[0028] Such as image 3 As shown, the skeleton 2 is sequentially welded by the left cylinder 2-1, the middle cylinder 2-2 and the right cylinder 2-3 to form a coaxial integral cylinder, and each cylinder is made of electrical pure iron, wherein , the size of the left cyl...

Abstract

The invention relates to a two-way displacement proportional electromagnet, which belongs to electromagnets, and solves the problems that the existing proportional valve adopts two unidirectional output electromagnets, and the overall performance is difficult to improve and the cost increases. The invention includes a shell, a skeleton, an armature, a left coil, a right coil, a left end cover, a right end cover, a left reed and a right reed. The invention adopts integral structure, simple assembly, easy debugging, realizes bidirectional displacement output, reduces processing cost, can be directly connected to the spool valve core, and realizes position proportional control of the spool valve core, and the output of the spool valve is proportional to the control signal The flow rate makes the proportional valve easy to use, better in performance, and easier to adjust the zero position.

Description

technical field [0001] The invention belongs to electromagnets, and in particular relates to a bidirectional displacement proportional electromagnet, which is used as an electro-mechanical conversion unit of a proportional directional control valve to convert an input control signal into a mechanical displacement signal according to a set ratio. Background technique [0002] With the continuous development of hydraulic drive technology and its high power-to-mass ratio, it has been widely used in various industries, and hydraulic drive is widely used in ships and construction machinery industries. As technology developed, precise proportional or servo control gradually replaced on-off control. In actual use, most systems do not have high requirements for frequency response, and servo valves have high requirements for oil cleanliness, which increases the cost, so proportional directional valves are more and more widely used. [0003] Proportional directional control valves ar...
