The invention discloses a flow control device of a valve. The flow control device of the valve mainly comprises a control rod, a left gear, a right gear, a left moving plate and a right moving plate, wherein the control rod is rotatably connected in a left spool chamber and a right spool chamber of a valve body; the left gear and the right gear are mutually meshed and are connected with the upper end of the control rod; the left moving plate and the right moving plate are connected with the lower end of the control rod; the end faces of the left moving plate and the right moving plate are jointed with end faces of a left fixed plate and a right fixed plate which are fixedly connected with the bottom of the spool chamber; rotary holes in the end faces of the left moving plate and the right moving plate are correspondingly and rotatably communicated with variable holes in the end faces of the left fixed plate and the right fixed plate; the variable holes in the end faces of the left fixed plate and the right fixed plate are communicated with a water flow hole in a valve cavity. During the working process, according to the requirements on water inlet flow for back washing of a filter material in a water treatment tank, the large fan-shaped water inlet rotary hole in the end face of the right moving plate can be adjusted at any time, and the small fan-shaped variable water inlet in the corresponding end face of the right fixed plate is in rotary communication, so as to effectively control the water inlet flow for back washing; the operation and control is convenient and fast, so as to obviously increase the working efficiency of water treatment.
Description
(1) technical field: the parts that the present invention relates to water treatment apparatus; Be specifically related to a kind of flow control device of valve.
(2) background technique: after prior art sewerage disposing device busy certain hour, what export purifies waste water because the filtrate in water treatment tank contains too much Impurity deposition and blocks filtrate, significantly reduce the output flow of purifying waste water and the pressure difference reducing water-in and water-out, need to carry out backwash to the filtrate in water treatment tank in time.In order to ensure carrying out in backwash process to the filtrate in water treatment tank, the flow of reason backwash is not excessive is causing filterins media run-off, and people will be provided with the constrictor of firm discharge usually in valve body limber hole, realize the control to sewer output flow.Because the constrictor of described firm discharge cannot adjust at any time to sewer output flow, such operator is everlasting when just needing and removes and installs the constrictor of different firm discharge in valve body limber hole, bring inconvenience to production work, seriously reduce the working efficiency of water treatment.
(3) summary of the invention: the deficiency existed for above-mentioned prior art, the object of the present invention is to provide a kind of flow control device of valve, and purport is convenient to control the adjustment at any time of sewer output flow, to improve the working efficiency of water treatment at work.
For achieving the above object, technological scheme of the present invention realizes like this, the flow control device of this valve, controlling rod is rotatably connected with in the left and right spool chamber being mainly included in valve body, intermeshing left and right gear is connected with in described controlling rod upper end, and be connected with left and right moving plate in described controlling rod lower end, the corresponding left and right stator end joined with being fixed on bottom spool chamber of end face of described left and right moving plate; It is that corresponding the rotation with the variable hole on left and right stator end face in hole that turn on left and right moving plate end face is communicated with; Variable hole on described left and right stator end face communicates with body cavity water flow passage hole.
The present invention is by taking said structure, during work, the large and small needs of backwash flow of inlet water are carried out according to filtrate in water treatment tank, adjust large fan-shaped water inlet on right moving plate end face at any time and turn hole, on corresponding right stator end face, little fan-shaped variable water inlet is rotated and is communicated with, and achieves the effective control to backwash flow of inlet water.Compared with the existing technology, convenient operation and control is quick, significantly enhances the working efficiency of water treatment.
