Abstract
The utility model provides an electromagnetic control non-return valve which comprises an electromagnet. The electromagnet is connected with a main valve seat through a main valve connector. The electromagnetic control non-return valve is characterized in that: the electromagnet has an armature, the armature is connected with an awl valve core, a front end awl portion of the awl valve core seals a pilot hole on the main valve connector, the main valve seat is provided with a main valve core, one end of the main valve core is provided with a spring, and the other end of the spring is connected to an interior portion of the main valve connector. The electromagnetic control non-return valve makes the design of an oil passage become simple, can realize remote control operation by using an electrical control form, and is particularly important in a system needing an emergency function, and at the same time, the closing time of the valve can be adjusted by changing damping according to specific needs.
Description
Technical field
The utility model relates to the hydraulic system technical field, the Electromagnetic Control one-way valve that concrete relating to used in a kind of hydraulic control system.
Background technique
The one-way valve that arrives commonly used in the hydraulic system is used for the break-make of some pipeline fluid in the controlled hydraulic system.Existing one-way valve is generally direct-drive one-way valve and Pilot operated check valve; Direct-drive one-way valve only can control oil channel folk prescription to flowing; Oppositely end; Although Pilot operated check valve can be controlled the two-way flow of fluid, the pressure oil that must provide controlling non-return valve whether oppositely to open in addition just must correspondingly be set up the proper functioning that other hydraulic element are guaranteed Pilot operated check valve in system; Simultaneously the pressure of controlling oil also there is certain requirement, not free controlled when one-way valve is closed after direction is opened simultaneously.
The model utility content
The utility model technical problem to be solved is, overcomes the problem that exists in the existing technology, and a kind of Electromagnetic Control one-way valve is provided.
For the technological scheme that addresses the above problem the utility model is such:
A kind of Electromagnetic Control one-way valve comprises electromagnet, and electromagnet connects main valve seat through the main valve connecting body; It is characterized in that electromagnet has an armature, armature connects a poppet valve core; The front end tapering of poppet valve core and the sealing of the pilot hole on the main valve connecting body; Main valve seat is provided with main valve plug, and main valve plug one end is provided with spring, and the spring the other end is connected the inside of main valve connecting body.
Be the awl sealing between main valve plug and the main valve seat.
Have the guide oil oil inlet hole on the main valve connecting body, guide's filler opening is provided with damping hole.
Have some compensating grooves on the excircle of main valve plug.
Adopt between main valve seat and the main valve connecting body and be threaded.
The utility model can adopt the form of electrical control to realize to remote-control operation so that the oil circuit design becomes simple, needs the system of emergency function particularly important at some, and simultaneously, the shut-in time of this valve can be regulated according to concrete needs change damping.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3; Electromagnet 12 its armature 1 link to each other with pilot poppet valve core 3 usefulness 2 screws, the state of the Push And Release of control poppet port, and main valve cover for seat 9 is threaded with main valve connecting body 13 usefulness; Seal ring 8 is housed on the main valve seat prevents directly ganging up of oil circuit B and guide oil; Also have two O shape ring recess on the main valve connecting body, be used to install seal ring 4,6 and isolate guide oil and oil return, guarantee simultaneously not leak when valve is on being installed in operation block; On the main valve connecting body, have damping hole 7; Main valve plug relies on the thrust and the main valve seat 9 of spring 14 closely to combine, and what the main valve oil sealing mouth 20 between main valve plug 17 and the main valve seat adopted is the awl sealing, to guarantee the reliability of sealing; What this valve adopted is the thread cartridge formula, and hydraulic fluid port 18, the sealing between 19 guarantee with seal ring 10.
Main valve housing 9 is connected with main valve connecting body 13 usefulness screw threads 16, middle seals with seal ring 8, prevents that first guide cavity fluid and B chamber fluid from ganging up; Guarantee the reliability that the guide partly works; Adopting the other function of this kind structure simultaneously is when primary sealing area sustains damage, and can change main valve seat easily, and need not to change whole one-way valve; Main valve seat has four through holes 18 on conical surface circumference; This through-bore axis and the certain angle of main valve plug movement direction make the resistance that flows of fluid reduce as far as possible, and pressure reduction is very little.The front end of main valve seat is made stage, is used for by putting seal ring 10, makes that manifold block oil-feed A and the B chamber in system cuts off.
The main valve connecting body inserts with being connected to of system oil-way piece and is threaded, and is threaded with being connected to of electromagnet 12.On the main valve connecting body, be processed with seal groove, seal ring 4 is installed, be used for preventing the external leakage of main valve; Simultaneously, have guide oil oil inlet hole (C) 7 and spill port 5 (D) on the main valve connecting body, oilhole (C) has damping hole 7; Decide the size of damping as required, on the main valve connecting body, also be processed with O shape ring recess, O shape circle 5 is installed; It mainly acts on is the sealing that prevents between the turnover of guide oil, guarantees the reliability that the guide partly works, and the front aperture of main valve connecting body is processed into stepped; Be used for retaining spring 14 and the opening degree that limits main valve plug 17 respectively, the spring chamber place is identical with oil-feed damping hole 7, and guide oil is got into smoothly.The rear end aperture of main valve connecting body and 1 sealing of pilot poppet valve core make the oil-feed of guide's part and oil return isolate, and oil back chamber communicates with spill port 5.
The push rod of guide's spool and electromagnet links together with screw 2, the pilot hole sealing of the tapering of its front end and main valve connecting body 13, and the push rod 1 of electromagnet 12 is realized by its contained spring thrust.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
