Device processed is laid out using circumference, be can be used as the connecting component between motor and valve body, is greatly saved electric machine controller and valve body
Arrangement space, the setting of spring be in order to use spring prepressing structure, screw rod one direction stress, eliminate hysterisis error.
Preferably, o type circle is provided with inside and outside the control lid plate.Prevent controller from revealing.
Preferably, the valve body and controller housing and spring bumper cover are stainless steel material.Outside guarantee valve body, controller
The service life of shell and spring bumper cover.
Preferably, all sides of the spool are horizontally disposed there are four locating piece, four locating pieces permutation in a ring
It is equally spaced, the locating slot being used cooperatively with locating piece is provided on the cavity inner wall of the valve body.Pass through locating piece and positioning
The cooperation of slot limits the rotation of spool.
Preferably, the spool and locating piece are an integral structure.
The beneficial effects of the utility model are:
The utility model can realize spool displacement continuous control, at the same have the advantages that it is at low cost, it is alternative expensive
Proportioning valve, can be achieved by the transmission of adjusting screw nut to client's different demands, using different drive ratios, Lai Shixian spool
The adjusting for controlling precision, since valve final output is flow, so the step-by-step adjustment of spool displacement can't be to output flow
Continuity impacts；Controller is laid out using circumference, be can be used as the connecting component between motor and valve body, is greatly saved
The arrangement space of electric machine controller and valve body, size is smaller than same type switch valve 1/3, proportioning valve is small by 1/2, makes the installation cloth of valve
Office is more exquisite compact, and since precision is adjustable, control performance is better than open loop proportioning valve and switch close to closed loop proportional valve
Valve.
