Description

A kind of electromagnetic gas valve

Technical field

The utility model relates to a kind of electromagnetic gas valve.

Background technique

The kind of solenoid valve is a lot, but great majority are to be shell with cast iron, and is whole heavy, complex structure, and the price height needs occasion light, simple, the low price purposes for some, does not have suitable solenoid valve.As when needing the air inlet road of Control of Automobile motor, just choosing is less than suitable solenoid valve.In order to suppress the high vibration of the appearance of motor in flame-out process, people have designed device---the U type electromagnetic gas valve that suppresses the engine misses vibration, its valve body is the cylinder of axial middle part indent, spool is a cylindrical body, driving mechanism adopts and pushes away, draws two electromagnet, drives the action of cylindrical gears and tooth sector; Resetting means is a clockwork spring shape Returnning spring; Limit stoper is that restraining groove, piece cooperate; Though be solenoid valve, complex structure, size is bigger, the manufacture cost height, the assembling difficulty, and reliability is difficult to guarantee.

Summary of the invention

The purpose of this utility model is: provide a kind of and can control air circuit breaker rapidly, up hill and dale, be particularly useful for the electromagnetic gas valve of car engine air admittance road control.

Concrete structural design scheme is as follows:

A kind of electromagnetic gas valve comprises valve body, spool and driving mechanism, it is characterized in that: described valve body is the V-type cylindrical tube, and an end is a suction tude, and the other end is a steam outlet pipe, and the centre is the cylinder die cavity; Described spool is the fan cylindricality; The fan cylindrical valve spool realizes that with cooperating by a transmission shaft of V-type cylindrical tube valve body this transmission shaft is installed on the gyration center of fan cylindrical valve spool, the dead in line of axis and valve body cylinder die cavity; Axle one end is overhanging, one end of U type connecting plate is fixed on it, the other end of U type connecting plate is connecting S type swing pull bar, the other end of swing pull bar is connecting electromagnet armature, be with spring on the electromagnet armature, the other end of electromagnet armature is positioned at the electromagnet main body, and the electromagnet main body is installed in the outside side of valve body.

The middle part of described fan cylindrical valve spool (non-cylinder) is a hollow shape, makes on the one hand spool reduce resistance to air inlet when open-circuit condition, has also alleviated the weight of spool on the other hand greatly; Cylinder die cavity in spool arc surface radially and the valve body matches, and keeps suitable gap between two fitting surfaces.

Described valve body is a L type cylindrical tube, and an end is a suction tude, and the other end is a steam outlet pipe, and the centre is the cylinder die cavity; Inlet, outlet tube's axis angle is 90 degree; Suction tude axis bias certain distance to guarantee when holding one's breath state having under the prerequisite of enough cooperation areas between valve body, spool two fitting surfaces, dwindles the physical dimension and the weight of valve body, spool.

The cylinder cavity bottom of described valve body is provided with beginning limiting stopper and each place of closed end limiting stopper, and the non-tight working surface on the spool has been simplified the design of position-limit mechanism effectively as confined planes.

Described electromagnet resets by spring.

The rotation of described spool is linked to each other with electromagnet with S type swing pull bar by U type connecting plate and realizes; The design of U type connecting plate has reduced the stroke of electromagnet; When U type connecting plate has been eliminated in the design of S type swing pull bar with valve core rotation, to the influence that involves of electromagnet armature displacement diametrically.

Useful technique effect of the present utility model is:

1, this device is reasonable in design, and is simple in structure, and part kind and quantity are few, assembling, easy to maintenance.

2, the utility model good manufacturability, valve body, spool and cover plate all can be taked high die casting aluminium processing, improved the inside and the surface quality of part, and the process-cycle are short, low cost of manufacture.

3, this electromagnetic gas valve is applicable to the occasion of the various heavy calibers of control, big flow gas circuit, especially is fit to the gas circuit control of motor car engine.

4, this electromagnetic gas valve is worked together with the different The controller that require according to different motor car engines, can be separately or with Fuel Cut Solenoid Valve to the motor action of stopping working, very solve the high vibration phenomenon that motor car engine occurs effectively in flame-out process, improve the travelling comfort of driving and the working life of motor and even car load.
