Using when scraping lip 1.6 and striking off to impurity, screen pipe 1.1 can be prototype again rapidly, and the circular arc that will be scraped lip 1.6 and be set as protrusion
Face, the internal diameter for scraping lip 1.6 is 1.05 times of 1.1 outer diameter of screen pipe, avoids stabbing screen pipe 1.1, enables screen pipe 1.1
It uses for a long time.
First control valve, the second control valve, third control valve, the 4th control valve, the 5th control valve and the 6th control valve
Structure is identical, includes valve body 51, valve rod 52, valve plate 53 and composite elastic valve seat 54, is equipped with valve rod at the top of the valve body 51
Frame, valve rod frame and valve body 51 are equipped with the through-hole of coaxial inner conductor, are equipped with valve plate 53 and composite elastic valve seat 54, valve rod in valve body 51
52 pass through through-hole and the fixed installation of valve plate 53, and composite elastic valve seat 54 is mounted between valve body 51 and valve plate 53；
Composite elastic valve seat 54 includes: connection ring 54.1, air bag 54.2, baffle ring 54.3, rotating ring 54.4 and determines ring 54.5, institute
It states and determines the inner wall that ring 54.5 is fixedly mounted on valve body 51, rotating ring 54.4, which is mounted on by connection ring 54.1 with center line, determines ring 54.5
It is interior, connection ring 54.1, rotating ring 54.4 with determine the composition of ring 54.5 U-type groove in be equipped with air bag 54.2, the opening of U-type groove, which is equipped with, keeps off
Ring 54.3, one end of baffle ring 54.3 are fixedly mounted on the upper of rotating ring 54.4, side wall and determine ring 54.5 at the other end of baffle ring 54.3
Contact, baffle ring 54.3 and 51 inner wall of valve body set between mounting distance as 2~10mm, usually 5mm；Composite elastic valve seat be with
Valve rod center line is center symmetrical structure；Clear water is loaded by water pocket, so that gas is separated with water pocket, water pocket can be for along air bag
54.2 middle line setting, avoids clear water always in the lower part of gas.
The connection ring 54.1, rotating ring 54.4 and determines the U-type groove of the composition of ring 54.5 and be an integral structure, rotating ring 54.4 and fixed
Ring 54.5 it is of same size.Clear water and compressed gas are filled in the air bag 54.2, clear water accounts for 54.2 inner volume of air bag
50%。
By being equipped with valve rod frame at the top of valve body 51, valve rod frame is easily installed valve rod 52, sets between valve rod frame and valve rod 2
There is sealing device, the rotation of valve plate 53 is controlled by the rotation of valve rod 52, valve plate 53 and valve seat form sealing surface, reach close
Valve seat is set as composite elastic valve seat 54 by the purpose of envelope, so that valve plate 53 is when closed, 53 extrusion cladding elastic seat of valve plate
54, and flexible composite elastic valve seat 54 is also to 53 1 extruding forces of valve plate, so that composite elastic valve seat 54 and valve
Sealing between plate 53 is more preferable, forms relatively reliable sealing, and when valve plate 53 has certain offset, composite elastic valve
Seat 54 is also capable of forming good sealing；By being provided with clear water and compressed gas in air bag, clear water accounts for the 50% of volume, so that
When extruding force of the valve plate to valve seat is excessive, when the gas in air bag can not form effective support to the rotating ring of valve seat, not by
The clear water of compression can form effective support to rotating ring, so that the reliability of valve seat is higher, so that the sealing performance of valve is more preferable.
Connection ring 54.1, rotating ring 54.4 form U-type groove with ring 54.5 is determined, and determine ring 54.5 and are fixedly mounted on inside valve body 51,
So that valve plate 53 squeezes rotating ring 54.4, so that rotating ring when the U-type groove open end of 53 driven torus 54.4 of valve plate turns to rotating ring 54.4
54.4 more squeeze rotating ring 54.4 to U-type groove medial movement, valve plate 53, and the sealing force between valve plate 53 and rotating ring 54.4 is stronger, makes
Valve plate 53 sealing effect it is more preferable, connection ring 54.1, rotating ring 54.4 with determine ring 54.5 for high resiliency, high tenacity metal material
Matter, so that composite elastic valve seat 54 is more durable compared to rubber valve seat, compared to metal seat valve, the power of opening closing valve
Square is smaller；Air bag 54.2 is installed in U-type groove, filled with high pressure gas in air bag 54.2, high pressure gas in air bag 54.2
Pressure can be adjusted according to the pressure medium in valve, and air bag 54.2 can form rotating ring and support, so that rotating ring 54.4
Resilience performance is more preferable, relatively reliable；It is equipped with baffle ring 54.3 by the opening in U-type groove, when valve plate 53 squeezes rotating ring 54.4,
Baffle ring 54.3 is slided in the end face for determining ring 54.5, and rotating ring 54.4 is deviated, and baffle ring 54.3 can will be to composite elastic valve
Dielectric impedance outside seat 54, to be protected to the air bag 54.2 in U-type groove, so that the service life of air bag 54.2 is more
It is long；And this valve is not needed 53 eccentric setting of valve plate, so that the manufacture processing cost of valve is lower, structure is simpler.
Composite valve seat is externally provided with the tracheae being connected to air bag 54.2, and tracheae is equipped with baroceptor, and tracheae is equipped with control
Valve processed, tracheae are connected with high pressure gas holder, and the outlet of high pressure gas holder is equipped with control valve, the branch of inflation/deflation is additionally provided on the air bag 54.2
Pipe, branch pipe are equipped with exhaust valve, and baroceptor, control valve and exhaust valve are connect with MCU respectively.
The baroceptor is in real time by the pneumatic conveying measured to MCU, when measuring air pressure > setting maximum gas pressure value,
The MCU control exhaust valve is opened, and after exhaust valve receives the control signal of MCU, exhaust valve is opened, when setting atmospheric pressure value -5%
When setting atmospheric pressure value < measures the air pressure < setting setting atmospheric pressure value of atmospheric pressure value+5%, MCU controls exhaust valve closure, exhaust valve close
It closes, keeps the air pressure in air bag；When measuring air pressure < setting minimum air pressure value, MCU controls control valve and opens, and control valve is beaten
It opens, the gas in high pressure gas holder enters in air bag 54.2, sets when the setting setting of atmospheric pressure value -5% atmospheric pressure value < measures air pressure <
When determining the setting atmospheric pressure value of atmospheric pressure value+5%, MCU controls control valve and closes, and keeps the air pressure in air bag.By being provided in air bag
Clear water and compressed gas, clear water account for the 50% of volume, so that gas in air bag is not when extruding force of the valve plate to valve seat is excessive
When can form effective support to the rotating ring of valve seat, the clear water being not compressed can form effective support to rotating ring, so that valve seat
Reliability it is higher so that the sealing performance of valve is more preferable.It can be in real-time detection air bag by the baroceptor that is equipped with
Air pressure, and by the pressure value of setting, so that MCU limits air pressure in a certain range, so that under any circumstance
The pressure being able to maintain in air bag 54.2 is setup pressure value, to improve the reliability of sealing and make the power for being opened and closed valve
