Description
Technical field
The utility model relates to a kind of solenoid valve, specifically is a kind of electromagnetism gas flow modulating valve, can be used for the flow control of gas, liquid etc.
Background technique
Traditional gas electromagnetic valve structure mainly is to see that whether burner uses, and controls entering of combustion gas.Its control valve body has a joint to be used for being connected with the combustion gas valve seat, and by a valve plug when burner does not use, valve opening in the pipeline is covered, combustion gas can't be entered in the burner to guarantee safety.And when burner uses,, make valve plug and valve opening break away from again by the element drives valve plug action of control valve inside, combustion gas is entered in the burner, the demand for fuel of supply burner.The working principle of this kind electromagnetic valve structure is that inner electromagnetic coil energising is moved valve plug, valve plug and valve opening is broken away from, thereby supply combustion gas.In the prior art, valve plug is round platform (awl) shape, the corresponding with it funneling of valve opening, the shortcoming of this structure is to take place because parameters such as the voltage of control circuit, electric current have unstable situation, so it is not in place to cause valve plug to move easily, some skews are always arranged, and it is too small or excessive the gap to occur between valve plug and the valve opening, and in fact the flow of combustion gas does not conform to the actual flow of controlling, and the power difference that causes combustion gas to produce is very big.
Summary of the invention
In order to solve the above-mentioned shortcoming that exists in the prior art, the utility model purpose provides a kind of new solenoid valve that is used for flow controls such as gas, liquid, and concrete technological scheme is as follows:
A kind of gas flow modulating valve comprises housing, valve plug, Returnning spring, magnetic core and electromagnetic coil; Described housing is provided with valve opening and air outlet hole; Magnetic core is located in the cavity of housing; The valve plug end is provided with permanent magnet, and permanent magnet is corresponding with magnetic core, and valve plug is corresponding with the valve opening position; Returnning spring is connected with valve plug; Electromagnetic coil is installed in the housing, and magnetic core is housed in the electromagnetic coil; The magnetic force (repulsion) that switching electricity by electromagnetic coil produces and the effect of Returnning spring, the action of control permanent magnet is risen and is fallen thereby drive valve plug.The shape of valve plug is to be made of at least 2 concentric cylinders, and the descending head and the tail of each cylindrical body connect successively, and minimum cylindrical body is connected with magnetic core.The maximum cylindrical external diameter of valve plug is identical with the valve opening internal diameter.
As improvement, described housing comprises valve shell and the moving part shell two-part of magnetic, two airtight connections of part; Described valve plug, Returnning spring, valve opening and air outlet hole are located in the valve shell; Described magnetic core and electromagnetic coil are located in the moving part shell of magnetic.
Valve plug is provided with connecting rod, and connecting rod end connects permanent magnet.
Be cut off in the valve shell and be divided into upper and lower two cavitys, is provided with through hole in the middle of cutting off, described connecting rod passes through hole; Be provided with sealing gasket in the upper cavity, sealing gasket is located on the connecting rod, and when valve plug and valve opening were airtight, sealing gasket was sealed through hole; The external diameter of sealing pad envelope is less than the internal diameter of valve shell; Described air outlet hole is located in the lower chamber; Returnning spring is located between permanent magnet and the partition.
Be provided with seal ring between the moving part shell two-part of described valve shell and magnetic.Be provided with seal ring around the valve opening of described hull outside.
Valve opening is a truncated conical shape, and a less end of round platform links to each other with the cavity of described housing, and the maximum cylindrical external diameter of described valve plug is identical with a less end diameter of described round platform.
The utlity model has following advantage:
By the switching electricity of electromagnetic coil and the effect of Returnning spring, the action of control permanent magnet drives valve plug and rises and fall.The controlled rise of valve plug is in a certain section of cylinder identical gap, and the flow that has determined combustion gas etc. to discharge by air outlet hole is identical.Overcome the skew of the flow that the valve plug control deviation causes.Valve plug is made of the different cylindrical body of a plurality of external diameters, also can make this solenoid valve have the function of multilevel control charge flow rate, and body is, by of the control of electromagnetism line chart to the magnetic core stroke, and then the volume of control valve plug in valve opening, thereby control nearly tolerance.
