Abstract
A drive head device of a diaphragm angle type and pool bottom type mud valve relates to valves. A blot (11) of the drive head device penetrates through a mounting hole of an upper cover (9) to be meshed with internal threads of a mounting hole of a middle cover (3), a valve plate shaft (2) is provided with external threads, and the upper end of the valve plate shaft (2) sequentially penetrates through an axial hole of the middle cover (3), a center hole of a lower pressing plate (4), a center hole of a rubber cloth inserted diaphragm (5) and a center hole of an upper pressing plate (6) to be connected with a nut (7). Therefore, high failure rate of an original drive head caused by abrasion is avoided. According to simulated experiments, times of round-trip folding of the rubber cloth inserted diaphragm can reach more than twenty thousand. If turbidity of raw water is 2000 degrees, mud is discharged for eight times each day, then the service life of the rubber cloth inserted diaphragm is more than six years, replacement of the rubber cloth inserted diaphragm is convenient and fast, and the replacing process only needs ten minutes, thereby reducing maintenance cost for users. The valve can be matched with a solenoid operated four-way valve in use to perform programmable logical controller (PLC) automatic control, and running status of the valve can be monitored duly.
Description
Technical field
The utility model relates to the valve that plumbing is used, the driving head device of formula soil discharging valve at the bottom of especially a kind of barrier film angie type that is applied in sludge from sedimentation tank, the pond.
Background technique
At present in the plumbing industry, use the driving head device that makes institute's soil discharging valve at the sedimentation pond for water treatment spoil disposal, be that pressure source enters the oil hydraulic cylinder lower end by solenoid operated four-way valve, promote piston, piston shaft drives upwards operation of valve plate, and oil hydraulic cylinder upper end medium enters atmosphere by solenoid operated four-way valve, valve opening, otherwise, valve closing comes and goes operation, and piston cup and the wearing and tearing of oil hydraulic cylinder casing wall are bigger, during the turbid height of former water, spoil disposal frequency height, oil hydraulic cylinder are easily gone here and there the water pressure release, and valve can't open and close, and it is cumbersome to change the leather cup complexity, and workload is big.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, adopts rubber folder cloth diaphragm, and sludge discharge effects is good, and long service life is safeguarded the driving head device of formula soil discharging valve at the bottom of barrier film angie type, the pond easily.
Technological scheme that the purpose of this utility model adopts is, comprise that the valve shaft lower end is connected with valve plate, middle cover, press table, is bowl-shape rubber folder cloth diaphragm, top board, nut upper-end surface are equipped with the magnetic cylinder, capping device has Hall switch, bolt, its bolt passes the engagement of loam cake mounting hole and middle cover mounting hole internal thread, and valve shaft has the outside thread upper end to pass middle cover axle center hole, press table center hole, rubber folder cloth diaphragm center hole, top board center hole successively to be connected with nut.
The utility model drives piston type and changes to the driving of rubber folder cloth diaphragm formula, with rubber folder cloth diaphragm driving head is divided into upward chamber and following chamber, top board, press table are made the valve shaft strong point, the pliable and tough attribute of application of rubber, by pressure change barrier film angle direction, thereby reach the function of opening/shutting valve.Its working principle is: when pressure enters down the chamber by solenoid operated four-way valve, promote barrier film, rubber folder cloth diaphragm drives the upwards operation of valve shaft, valve plate, last chamber medium enters atmosphere by solenoid operated four-way valve, at this moment, 60 ° of rubber folder cloth diaphragm gradient matches for 60 ° with the loam cake gradient, and nut and top board support rubber folder cloth diaphragm bottom can not make rubber press from both sides the unlimited extensional of cloth diaphragm because of the size of pressure and break simultaneously; When valve closing, 60 ° of rubber folder cloth diaphragm gradient matches for 60 ° with the middle cover gradient, and valve plate location and press table support rubber folder cloth diaphragm bottom have guaranteed that rubber presss from both sides cloth diaphragm all the time in the raw simultaneously.In order to guarantee rubber folder cloth diaphragm quality, during processing vulcanized rubber folder cloth diaphragm, accompany nylon cord in the middle of the rubber folder cloth diaphragm.Magnetic cylinder when valve opening finishes on the nut and Hall switch induction are connected, and valve opening signal feeds back to the control room, and magnetic cylinder during valve closing on the nut and Hall switch disconnect, and the control room signal extinguishes.
The utility model, the high rate of fault of having avoided former driving head to produce because of fretting wear, through simulation, rubber folder cloth diaphragm comes and goes folding times and reaches more than 20,000 times, as raw water turbidity is 2000 degree, every day spoil disposal No. eight times meter, rubber folder cloth film working life is more than 6 years, the replacing of rubber folder cloth diaphragm is convenient and swift, ten minutes all replaceable finishing.Reduced user's maintenance cost.This valve and solenoid operated four-way valve are used and can enter PLC and control the running state of timing monitoring valve automatically.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is that the utility model and solenoid operated four-way valve are used the sectional structure schematic representation.
Among the figure: 1-valve plate 2-valve shaft 3-middle cover 4-press table 5-rubber folder cloth diaphragm 6-top board 7-nut 8-magnetic cylinder 9-loam cake 10-Hall switch 11-bolt 12-solenoid operated four-way valve.
Embodiment
As shown in drawings, be that the utility model and solenoid operated four-way valve 12 are used embodiment.Comprise that valve shaft 2 lower ends are connected with valve plate 1, middle cover 3, press table 4, are bowl-shape rubber folder cloth diaphragm 5, top board 5, nut 7 upper-end surfaces are equipped with magnetic cylinder 8, loam cake 9 devices have Hall switch 10, bolt 11, it is characterized in that, bolt 11 passes the engagement of loam cake 9 mounting holes and middle cover 3 mounting hole internal threads, and valve shaft 2 has the outside thread upper end to pass middle cover 3 axle center holes, press table 4 center holes, rubber folder cloth diaphragm 5 center holes, top board 6 center holes successively to be connected with nut 7.
The utility model can be applicable to the angie type soil discharging valve, or formula soil discharging valve at the bottom of the pond.
Claims (1)
1. barrier film angie type, the driving head device of formula soil discharging valve at the bottom of the pond, comprise that valve shaft (2) lower end is connected with valve plate (1), middle cover (3), press table (4), be bowl-shape rubber folder cloth diaphragm (5), top board (5), magnetic cylinder (8) is equipped with in nut (7) upper-end surface, loam cake (9) device has Hall switch (10), bolt (11), it is characterized in that, bolt (11) passes loam cake (9) mounting hole and the engagement of middle cover (3) mounting hole internal thread, and valve shaft (2) has the outside thread upper end to pass middle cover (3) axle center hole successively, press table (4) center hole, rubber folder cloth diaphragm (5) center hole, top board (6) center hole is connected with nut (7).
