Effect is conducive to the generation for avoiding blocking.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
A kind of delay Slow Close control valve with dirt eliminating function as shown in Figure 1, including valve body 1, valve seat 2, sealing ring pressure
Plate 3, O-ring seals 4, valve disc 5, valve rod 6, bypass pipe 7, diaphragm 8, pressing plate 9, spring 11, blowdown valve 12, blowdown bypass pipe
13, other pipe 15, instrument needle-valve 16, maintenance blowdown orifice plate 17 and rubber gasket 18 is discharged in the valve deck 14 with cavity, medium.
Valve seat 2 is installed on inside valve body 1,6 lower end of valve rod can opposite valve seat 2 slidably encapsulation on valve seat 2.Valve disc 5 is pacified
Loaded on valve rod 6, valve rod 6 and valve disc 5 can synchronization lifting movement, valve disc 5 and valve seat 2 form the sealing of controllable valve opening and closing
It is secondary.For the center shaft section of valve disc 5 in I-shaped, 5 lower end of valve disc is equipped with sealing ring pressing plate 3, valve disc 5 and sealing ring pressing plate 3 it
Between O-ring seals 4 are installed, can be sealed by the sealing ring 4 of 5 bottom of valve disc between valve disc 5 and valve seat 2, improve valve disc 5 with
The reliability sealed between valve seat 2 realizes the zero leakage when valve is closed.
Valve deck 14 is installed on valve body 1, and the position that valve deck 14 and valve body 1 are correspondingly connected with is hatch frame, and valve body 1 is opposite
The junction of valve deck 14 is set as concave configuration, is conducive to the storage for depositing miscellaneous dirt.Diaphragm is equipped between valve deck 14 and valve body 1
8, prevent dielectric leakage.The upper end of valve disc 5 is installed on the downside of diaphragm 8, is equipped on the upside of diaphragm 8 opposite with 5 upper end of valve disc
The pressing plate 9 answered, pressing plate 9 are connected and fixed using nut 10.9 upper end of pressing plate is equipped with spring 11, is equipped with inside the cavity of valve deck 14
The installation end plate of spring 11,11 upper end of spring are fixed on inside the mounting groove of installation end plate, and 9 upper end of pressing plate is compressed by spring 11
The formation of valve disc 5 with 8 downside of diaphragm compresses structure.Valve disc 5 is closed valve with the cooperation sealing of valve seat 2 by the pretightning force of spring 11
It closes, and there are when medium inside valve deck 14, valve disc 5 can be acted on by the pressure of 14 cavity interior media of valve deck.
It is equipped with maintenance blowdown orifice plate 17 at the top of valve deck 14, is equipped with seal washer between valve deck 14 and maintenance blowdown orifice plate 17
18.It overhauling blowdown orifice plate 17 and is equipped with the other pipe 15 of medium discharge, the internal diameter that other pipe 15 is discharged in medium is less than the internal diameter of bypass pipe 7,
Medium is discharged on other pipe 15 and is equipped with instrument needle-valve 16.
The bypass pipe 7 for being connected to 1 input end of 14 cavity of valve deck and valve body is equipped between valve deck 14 and valve body 1, bypass pipe 7 is arranged
In the bottom position of valve deck 14, be conducive to the liquid level for improving medium recoil.The bottom of valve deck 14 is equipped with blowdown bypass pipe 13, blowdown
Bypass pipe 13 is equipped with blowdown valve 12.
The delay Slow Close control valve with dirt eliminating function is when in use: when valve inlet end, medium is acted on valve disc 5
Pressure when being greater than the pretightning force of spring 11, valve disc 5 and valve rod 6 are jacked by medium so that valve opening, while bypass pipe 7 can
The injected media into 14 cavity of valve deck.
When medium reaches medium discharge side pipe 15 in 14 cavity of valve deck, while medium is discharged other pipe 15 and drains to outside valve deck 14
15 internal diameter of other pipe is discharged since 7 internal diameter of bypass pipe is greater than medium in intracavitary medium, and the intracavitary medium injection rate of valve deck 14 is greater than excretion
Speed, after a period of time, valve deck 14 is intracavitary fill medium after pressure persistently increase, until acting on pressure on diaphragm 8
When reaching valve closing pressure, valve disc 5 is depressed and closes valve.
After valve inlet end pressure venting, the intracavitary medium of valve deck 14 can be excreted in valve preceding pipeline along bypass pipe 7,
Play the role of recoil, be conducive to avoid miscellaneous dirty deposition blocking pipeline in valve preceding pipeline, air can be discharged along medium other pipe 15 into
It is intracavitary to enter valve deck 14.
Impurity in 14 cavity interior media of valve deck can occur to settle inside 14 cavity of valve deck and be deposited on diaphragm 8
On, therefore the valve, after long time running, the miscellaneous dirt in medium can pass through the row of opening in 14 bottom deposit of valve deck at this time
Dirty valve 12 perhaps overhauls the dirt and impurity of the discharge of blowdown orifice plate 17 or cleaning removal deposition.
