Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
See figures.1.and.2, high accuracy self-operated flow control valve of the present utility model comprises:: valve body 1, valve gap 2, spring strut 15 Non-follow control assembly and automatic control unit, wherein, valve gap 2 and spring strut 15 are separately positioned on the upper/lower terminal of valve body 1, valve body 1 is formed with pressure guide hole 17, Non-follow control assembly is arranged on valve gap 2 and in control valve cavity, automatic control unit is arranged in control valve cavity.Introduce the structure of Non-follow control assembly and automatic control unit below respectively.
See figures.1.and.2, Non-follow control assembly comprises: manual opening stem 3, magnetic card lock 16 and upper moving plate 5, and magnetic card lock 16 and upper moving plate 5 are separately positioned on the upper/lower terminal of manual opening stem 3, and upper moving plate 5 in the form of sheets.In addition, the end face of valve gap 2 is also provided with sign board 4, the inwall of valve body 1 is provided with regularly lower still 6, lower still 6 is in horizontal positioned, and upper moving plate 5 is with lower still 6 close contact and the two all has the through hole passed through for liquid.Upper moving plate 5 and lower still 6 preferably adopt stainless steel to make.Hand rotation manual opening stem 3, manual opening stem 3 drives upper moving plate 5 to rotate, when the through hole on upper moving plate 5 and lower still 6 overlaps completely or partially overlaps, control valve is opened, liquid namely by, uninterrupted is determined by the coincidence degree of the through hole on upper moving plate 5 and lower still 6, and directly can read from sign board 4.
See figures.1.and.2, automatic control unit comprises: valve rod 8 automatically, is set in the back-up ring 7 on automatic valve rod 8, upper valve plug sheet 9, lower valve plug sheet 10, film pad 11, diaphragm 12 and spring bracket 13 from top to bottom successively regularly.Wherein, the range that moves downward for controlling automatic control unit of back-up ring 7; Upper valve plug sheet 9 and lower valve plug sheet 10 are for the size of liquid flow path opening on control valve body 1; Diaphragm 12 has the lug boss arched upward up or down, and ringwise, the edge of diaphragm 12 is fixed on the inwall of spring strut 15 lug boss; The lower end cover of spring bracket 13 has spring 14, and spring 14 is placed in spring strut 15.When there is pressure reduction change between water intake and water outlet, there is deformation in diaphragm 12, and drive automatic valve rod 8, lower valve plug sheet 10, upper valve plug sheet 9, back-up ring 7 to rise or decline, thus control the size of liquid flow path opening on valve body automatically, former setting flow is finally made to remain unchanged, achieve the automatic control of fluid flow, and there is higher precision.
As the preferred scheme of one, the outer side surface of upper valve plug sheet 9 and the outer side surface of lower valve plug sheet 10 are respectively formed with at least three drag reduction muscle, drag reduction muscle effectively reduces valve plug sheet 9, friction between lower valve plug sheet 10 and valve body 1, further increases the precision automatically controlled.
