Abstract
The utility model discloses a mud valve for a waterworks or a sewage plant, comprising a tee valve body, a hydraulic cylinder and a feedback device. Wherein an inlet axis and an end encloser interface axis of the tee valve body forms an angle of 135 degrees while an outlet axis and the end encloser interface axis forms an angle of 90 degrees. The feedback device consists of a magnet and a dry reed pipe arranged in a hole at the center of the cylinder cover. The mud valve is structured simply and reasonably, performs steadily and reliably, opens quickly and keeps long service life.
Description
The utility model relates to the special-purpose soil discharging valve in a kind of supply and drain water system.It is mainly used in the mud discharging device of waterworks and sewage treatment works.
At present, in supply and drain water system, generally adopt the angie type that surges by soil discharging valve.Because this valve adopts the mechanism of stop valve in design, make this valve after closing, silt can be deposited on the valve plate, and heavy more tight more, heavy more thick more.When driving valve, valve rod will bear the gravity and the surface friction drag of silt like this, so not only opening speed is slow for this valve, and will tend to cause valve plate and valve rod to come off or will cause valve plate not open.The sealability of this valve is also very poor simultaneously, usually causes and leaks.More than these two kinds of numbness diseases all can give using of user and keep in repair and cause very big trouble.Do not have the signalization feedback means on the existing in addition soil discharging valve, therefore will in automated management system, should use the very difficulty that just seems.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of simple and reasonable, stable and reliable for performance, open valve rapidly, long service life, and can feed back the fluid-operated piston angie type soil discharging valve of slurry valve working condition automatically.
The purpose of this utility model is to reach by following measure: this angie type soil discharging valve is made up of three way valve, valve plate, valve body end cap, cylinder body, piston rod, piston, cylinder cap and elbow.Wherein to rotate to the axis angle of three way valve end cap mouth in the direction of the clock be 135 ° ± 5 ° to the import axis of three way valve, and the axis angle of the outlet axis of three way valve and three way valve end cap mouth is 90 ° ± 5 °.In three way valve, also have together with the import axis at 45 ± the plane sealing mouth at 5 ° of angles.And by the oil hydraulic cylinder that cylinder body, piston rod, piston, cylinder cap constitute is to link into an integrated entity by valve body end cap and three way valve.Wherein valve body end cap can be passed in the bottom of piston rod, floats with the valve plate that is positioned at three way valve and be connected in its lower end.
The utility model can also be fixed a magnet in the upper-end surface of piston rod, and a dry reed-pipe is installed in the central small hole of cylinder cap, makes this magnet and dry reed-pipe constitute signal feedback device.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the structural drawing of three way valve in the utility model.
The utility model will be described in further detail down in conjunction with the embodiments: this fluid-operated piston angie type soil discharging valve is to be made of three way valve (1), valve plate (3), valve body end cap (5), cylinder body (7), piston rod (4), piston (6), cylinder cap (8) and elbow (11).Wherein the structure of three way valve (1) is very unique.Become 135 ° angle between its import axis and its end cap mouth axis.And become 90 ° angle between its outlet axis and its end cap mouth axis.In three way valve (1), also has together plane sealing mouth (2) with import axis angle at 45.The oil hydraulic cylinder of being made up of cylinder body (7), piston rod (4), piston (6), cylinder cap (8) is to link into an integrated entity by valve body end cap (5) and three way valve (1), and is positioned at the top of valve body end cap (5).And the bottom of piston rod (4) can pass valve body end cap (5), floats with the valve plate that is positioned at three way valve (1) (3) and be connected in its lower end.Be fixed with a magnet (10) in the upper-end surface of piston rod (4) in addition, a dry reed-pipe (9) meanwhile also is installed in the central small hole of cylinder cap (8), and this magnet (10) and this dry reed-pipe (9) can constitute the signal feedback device of this angie type soil discharging valve working condition of feedback.At last with the outlet Joint of elbow (11) with three way valve (1).
This valve is work like this: when needing valve opening, send out earlier the valve instruction, so piston stroking upward, magnet and dry reed-pipe are approaching, and two contacts in the dry reed-pipe are closed down with regard to magnetic force, and this signal feed back that just valve can have been opened is gone back.Meanwhile the valve plate in the three way valve is also up under the drive of piston rod, opens the sealing mouth in the valve body, and mud, is discharged through water outlet and elbow by the back cavity of sealing mouth to three way valve by the ante-chamber of three way valve again.When needing valve closing, the instruction of sending throttle down earlier, so descent of piston, magnet leaves dry reed-pipe, two contact bullets in the dry reed-pipe from, this just can go back the buttoned-up signal feed back of valve.Valve plate in the same three way valve is also descending under the drive of piston rod, and with the sealing of the sealing mouth in the three way valve, mud is blocked in the ante-chamber of valve body.This moment, mud only contacted with the valve plate bottom with ante-chamber, and the back cavity of valve body to be clean room communicate with atmosphere.
The utility model has following advantage compared to existing technology: this hydraulic piston angle mud-discharging valve Simple in structurely tightly play, stable and reliable for performance, thoroughly removed the phenomenon that valve plate comes off and do not open, Reduced simultaneously the resistance of valve, made out valve rapid. It has shortened the keying stroke of valve plate, from And the smaller volume weight of valve is reduced, the joint medicine material and processing cost. It makes simultaneously Long with the life-span. It can also accurately automatically feed back the working condition of slurry valve in addition.
