Abstract

The utility model discloses an electromagnetic valve which can be directly screwed in a three-way joint of a turning pipe. The electromagnetic valve can be used for the opening and the closing of the conveyance transmission and the timing and quantitative automation control of liquid and gas of machinery, chemical industry, oil material, refrigeration and precision equipment. The utility model has the advantages of simple structure, quick reaction, reliable use, pipe material saving, little medium leakage at an interface position, etc., and an electromagnetic valve and a hollow bolt which are connected to the middle part of a medium conveying pipe are omitted.

Description

Direct wresting-in type solenoid valve

The utility model relates to a kind of solenoid valve, particularly a kind of solenoid valve that can directly be screwed into the steering tube tee union, this solenoid valve can be used for machinery, chemical industry, oil plant, switching is transmitted in conveying freezing, the precision equipment liquids and gases and automation is at regular time and quantity controlled.

At present, our common employed solenoid valve can only be connected the centre of medium transfer tube, can not directly be screwed into the steering tube tee union, so promptly waste tubing, again easily in the jointing leakage medium, especially at the precision height, on the volume small device, also on the steering tube tee union, do not use solenoid valve at present.

The purpose of this utility model is that a kind of direct wresting-in type solenoid valve will be provided, and it has solved the problem that can not directly be screwed into solenoid valve in medium transport on the steering tube tee union.

The purpose of this utility model is to realize like this, this solenoid valve comprises valve body, the top cap, spring, pellet shot from a slingshot, valve pushes away post, anti-lubricating pad, coil, the coil insulation frame, electromagnet, the solenoid valve capping, adjust critical pieces such as double-screw bolt, its valve body is divided into three parts in left center right, left part has a hole in it, the end that keeps left in the hole is processed with internal thread, the stepped shape top cap that has through hole in the middle of the outside is threaded withstands on pellet shot from a slingshot in the hole by spring, left part outside at valve body is processed with screw thread, (be used for join to steering tube tee union), screw thread right side have one and the through hole that communicates of endoporus; The middle part has an aperture and valve is pushed away post installs in it; Right part has a macropore, the insulating frame that is wound with coil is housed in the hole, the right side of coil insulation frame, anti-lubricating pad is equipped with in the bottom of macropore, the solenoid valve capping is encapsulated in the right-hand member of valve body, in the endoporus of solenoid valve capping electromagnet is housed, the center hole of solenoid valve capping is equipped with the adjustment bolt, has leading out terminal in the solenoid valve capping.

The utility model is owing to adopted said structure, make the simple in structure of this kind solenoid valve, reaction is fast, use reliably, omitted and be connected medium transport pipe middle solenoid valve and hollow bolt, give and use the machinery of solenoid valve to bring new revolution, it is higher that it is particularly suitable for being applied in precision, on the volume small device, have saving tubing, be difficult for advantages such as leakage medium at jointing.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is direct wresting-in type solenoid valve overall structure cut-away view.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing, this solenoid valve comprises that valve body 1, top cap 2, spring 3, pellet shot from a slingshot 4, anti-lubricating pad 5, valve push away critical pieces such as post 6, coil 7, coil insulation frame 8, electromagnet 9, solenoid valve capping 10, adjustment double-screw bolt 11.Its valve body 1 is divided into three parts in left center right, left part has a hole in it, the end that keeps left in the hole is processed with internal thread, the stepped shape top cap 2 that has through hole in the middle of the outside is threaded withstands on pellet shot from a slingshot 4 in the hole by spring 3, left part outside at valve body 1 is processed with screw thread, this screw thread is used for and the steering tube tee union joins, and the screw thread right side has one and the through hole 12 that communicates of endoporus; The middle part has an aperture and valve is pushed away post 6 installs in it; Right part has a macropore, the insulating frame 8 that is wound with coil 7 is housed in the hole, the right side of coil insulation frame 8, anti-lubricating pad 5 is equipped with in the bottom of macropore, solenoid valve capping 10 is encapsulated in the right-hand member of valve body 1, electromagnet 9 is housed in the endoporus of solenoid valve capping 10, and the center hole of solenoid valve capping 10 is equipped with adjusts double-screw bolt 11, has leading out terminal 13 in the solenoid valve capping.

When specifically implementing the utility model, this solenoid valve can be designed to open in usual, or Normally closed type, and the valve part also can be divided into cylinder type, piston type, cone type, opposite hole type various ways, can be divided into high pressure, low pressure, high temperature, low temperature again according to environment of applications.During use, the valve body 1 left part threaded end of this solenoid valve directly is screwed in the steering tube tee union, leading out terminal 13 connects corresponding power supply, saved original hollow bolt, when medium mobile needs electromagnetic valve, solenoid valve obtains power supply from lead end 13, after coil 7 energisings, be positioned at the length that electromagnet 9 conduits in the solenoid valve capping 10 are shorter than the intermediate hole of coil 7, electromagnet is inevitable to push away the motion of post 6 directions to valve, push away post 6 and promote that pellets shot from a slingshot 4 overcome the elastic force of spring 3 and the tight card of medium entrance point of top cap 2 through holes closes, play sealing process, when not needing electromagnetic valve, the solenoid valve outage, pellet shot from a slingshot 4 is kept in the center under the effect of spring 3, valve is opened automatically, the medium proper flow.
