Description
Technical field
The utility model relates to valve field, particularly relates to a kind of high pressure guide mortor operated valve.
Background technique
The kind of valve is a lot of in the market, and especially high pressure electric gate and pilot solenoid valve are two kinds.
The principle of existing high pressure electric gate is that high-voltage electric ball valve, when work, is the opening and closing by Electric Machine Control spool ball, when clockwise 90 ° of driven by motor spool ball, ball valve is in open mode, and now the type bit switch in ball valve disconnects, and motor stops the rotation; When 90 ° of driven by motor spool ball reversions, ball valve is in closed condition, and now the type bit switch in ball valve disconnects, and motor stops the rotation; .
The shortcoming of this high pressure electric gate is: the opening and closing all by Electric Machine Control of ball valve, in this control mode, the Placement more complicated of the rotatingshaft of motor and spool ball, wherein mainly contain 220V motor, coupling, bearing, turbine etc., whole like this valve group volume is large especially, thereby can cause power of motor larger.
The working principle of pilot solenoid valve is that, when fluid enters valve body, the pressure of segment fluid flow and the pressure of disc spring on valve body, make the diaphragm group in valve body be pressed in firmly on primary valve; When valve closing, electromagnetic coil energising in valve body produces magnetic field and sucts movable core assembly, pilot port in valve body is opened, now in diaphragm group, the high-pressure liquid of part flows to water outlet by pilot port, thereby the hydrodynamic pressure of part declines in diaphragm group, make the pressure of part in water intake pressure and diaphragm group produce pressure difference, now diaphragm group moves upward, thereby open primary valve, make to import and export connection;
When coil losing electricity, movable core assembly moves downward, and blocks pilot port, in diaphragm group, partial pressure sharply rises, and the pressure of intake-outlet is identical, because the pressure of diaphragm group bottom surface has the upper partial pressure of diaphragm group, does not produce greatly pressure difference, diaphragm group moves downward, and closes primary valve.
The shortcoming of this pilot solenoid valve is: the Reliability of Microprocessor of valve is poor, and especially can not there be any magnetic interference in the surrounding of valve, higher to environmental requirement, when valve events, if there is magnetic interference or electric wire, opens circuit, and will cause solenoid valve to quit work.
In sum, for the defect of prior art, need especially a kind of high pressure guide mortor operated valve, thereby solve above two kinds of problems that valve is mentioned.
