Abstract
The utility model discloses a kind of piston type regulating valve, comprise valve body, connecting rod, piston, adjusting pressing plate, adjusting screw, valve seals, valve shaft and drive unit, valve seals is by adjusting screw and regulate gland to be fixed on valve body, piston is arranged in valve body, drive unit is installed on a side of valve body, one end of connecting rod is connected with drive unit, and its other end is connected with piston.The utility model valve body is designed to an entirety, has high negotiability, and aperture and flow are linear, and degree of regulation is high, effective.Inner casing has fairshaped water conservancy diversion rib to be connected with shell, and stainless steel piston, by reliably guiding slip, is stopped to produce or move not smooth.The end face globulate of inner casing upstream, makes current form a progressive formation, and piston operates with the connecting rod that is arranged on valve inner, does not contact with medium, and flow resistance is little.Piston type regulating valve adopts metal and rubber sealing structure, and good sealing effect, can reach zero leakage.
Description
Technical field
The utility model relates to a kind of modulating valve, relates in particular to a kind of piston type regulating valve.
Background technique
In fluid delivery process, modulating valve has accounted for 30～40% ratio, and modulating valve is of a great variety, as the valve classes such as butterfly valve, gate valve, stop valve can play certain effect such as adjusting rate-of flow, pressure after adding automatic regulating system, but often exist, degree of regulation is not high, many difficult problems such as cavitation greatly, easily occur flow resistance, can not meet the requirement that system regulates.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of piston type regulating valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises valve body, connecting rod, piston, adjusting pressing plate, adjusting screw, valve seals, valve shaft and drive unit, described valve seals is fixed on described valve body by described adjusting screw and described adjusting gland, described piston is arranged in described valve body, described drive unit is installed on a side of described valve body, one end of described connecting rod is connected with described drive unit, and its other end is connected with described piston.
Further, between described piston and described valve body, be provided with piston packing.
The beneficial effects of the utility model are:
The utility model piston type regulating valve valve body is designed to an entirety, has high negotiability, and aperture and flow are linear, and degree of regulation is high, effective.Inner casing has fairshaped water conservancy diversion rib to be connected with shell, and stainless steel piston, by reliably guiding slip, is stopped to produce or move not smooth.The end face globulate of inner casing upstream, makes current form a progressive formation, and piston operates with the connecting rod that is arranged on valve inner, does not contact with medium, and flow resistance is little.Piston type regulating valve adopts metal and rubber sealing structure, and good sealing effect, can reach zero leakage.
