Abstract

A kind of Proportional valve, comprise valve body, in described valve body, be provided with valve pocket, a side of described valve body is provided with electromagnet, and the opposite side of described valve body is provided with spring, in described valve pocket, be provided with spool, one end of described spool is exposed and is provided with positioned edge limit from the opposite side of valve body, and the push rod in described electromagnet stretches into valve pocket from one end of valve body, and the material of described valve body is transparent plastic, the Proportional valve of new structure, simple in structure.By forming plane positioning between positioned edge limit and valve pocket, and can control the initial position of spool, improved the positioning precision of spool and valve pocket, and whole valve body adopts transparent plastic manufacture, can accurately see the runnability that it is inner, can be unexpectedly may be early discovery mistake and keep in repair, greatly improved the working life of Proportional valve.

Description

Proportional valve
Technical field
The utility model relates to a kind of valve, particularly a kind of Proportional valve.
Background technique
Proportional valve is also referred to as being proportional flow control valve, a kind ofly according to electrical signal, to regulate pro rata and the flow of stable oil circuit, thereby change a kind of valve of actuator's movement velocity, traditional Proportional valve, spring is arranged on to valve core inside, and the active force of spring acts on the push rod of electromagnet all the time, affects the control accuracy of valve, and the detection system imperfection of whole Proportional valve, if there is certain part to make a mistake, can not be easy to find out and keep in repair.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, easy to use, highi degree of accuracy and is convenient to check and the Proportional valve of maintenance.
For solving the problems of the technologies described above, the utility model provides a kind of Proportional valve, comprise valve body, in described valve body, be provided with valve pocket, a side of described valve body is provided with electromagnet, and the opposite side of described valve body is provided with spring, in described valve pocket, be provided with spool, one end of described spool is exposed and is provided with positioned edge limit from the opposite side of valve body, and the push rod in described electromagnet stretches into valve pocket from one end of valve body, and the material of described valve body is transparent plastic.
The utility model improves to be had, and the material of described spool is plastics.
The utility model improves to be had, and on the surface of contact of described valve pocket and valve body, is provided with seal ring.
The utility model improves to be had, and described seal ring is O RunddichtringO.
The utility model improves to be had, and described positioned edge limit and spool are one-body molded.
The beneficial effects of the utility model are: the Proportional valve of new structure, and simple in structure.By forming plane positioning between positioned edge limit and valve pocket, and can control the initial position of spool, improved the positioning precision of spool and valve pocket, and whole valve body adopts transparent plastic manufacture, can accurately see the runnability that it is inner, can be unexpectedly may be early discovery mistake and keep in repair, greatly improved the working life of Proportional valve.
Accompanying drawing explanation
The structural representation that accompanying drawing 1 is Proportional valve of the present utility model.
Label declaration: 1-valve body; 2-valve pocket; 3-electromagnet; 4-spring; 5-spool; 51-positioned edge limit.
Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being realized object and effect, below in conjunction with mode of execution and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1, the utility model shown in accompanying drawing provides a kind of Proportional valve, comprise valve body 1, in described valve body 1, be provided with valve pocket 2, a side of described valve body 1 is provided with electromagnet 3, and the opposite side of described valve body 1 is provided with spring 4, in described valve pocket 2, be provided with spool 5, one end of described spool 5 is exposed and is provided with positioned edge limit 51 from the opposite side of valve body 1, and the push rod in described electromagnet 3 stretches into valve pocket 2 from one end of valve body 1, and the material of described valve body 1 is transparent plastic.
By the positioned edge limit 51 of spool 5 one sides and the plane positioning between valve pocket 2, can say that the initial position of spool 5 is controlled at valve pocket 2 one lateral section positions all the time, improved the positioning precision of spool 5 with valve pocket 2.
On the other hand, between the push rod of electromagnet 3 and spool 5 initial positions, leave some gaps, the initial position while making electromagnet 3 keep away electromagnet 3 startup in low current situation, can export a constant thrust, has improved the control progress of Proportional valve.
Valve body 1 by transparent plastic arranges, and can effectively see the runnability of valve body 1 inside, so that comparative example valve the earliest carries out inspection and repair, has improved the working life of whole Proportional valve.
In the present embodiment, the material of described spool 5 is plastics, can when realizing Proportional valve effect, alleviate the volume of whole Proportional valve.
In the present embodiment, on the surface of contact of described valve pocket 2 and valve body 1, be provided with seal ring, seal ring has effectively promoted the sealing effect of whole Proportional valve.
Concrete, described seal ring is O RunddichtringO.
In the present embodiment, described positioned edge limit 51 is one-body molded with spool 5.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
