Detailed description of the invention
A kind of engine air door fitting unit, including drag lever 1, support threaded rod 2, valve platen seat 3,
Platen pillar 4, annular platen 5, it is characterised in that: drag lever 1 respectively with support threaded rod 2, valve
Platen seat 3 is flexibly connected；Support the compression of threaded rod 2 tailing screw flight specification and cylinder cap top plane distribution top board
Screwed hole is identical；There are valve collet installing hole, disk and ring below valve platen seat 3 in annular platen 5 center
On shape platen 5, correspondence is respectively arranged with two positioning through hole；Valve platen seat 3 He is inserted at platen pillar 4 two ends respectively
Annular platen 5 on positioning through hole and be fixedly connected by welding.
For in anti-air-stop gate installation process, cause operational error, preferably at the shaft of drag lever 1 because hands is sliding
Afterbody carries out " annular knurl " anti-skidding process.
Preferably drag lever 1 with the connected mode supporting threaded rod 2 is: drag lever 1 shaft head is milled with
Two head parallel surfaces, hinged connection hole on head parallel surface, support threaded rod 2 head and be milled with location U-shaped
Groove, hinged connection hole on groove both wings；The head parallel surface thickness of drag lever 1 is equal to or slightly less than supporting spiral shell
Rasp bar 2 positions the width of U-lag；Drag lever 1 and support threaded rod 2 pass drag lever 1 by bolt
Hinged through hole on head parallel surface and the hinged through hole supported on the U-lag both wings of threaded rod 2 head location enter
Row is flexibly connected.
Preferably drag lever 1 with the connected mode of valve platen seat 3 is: be milled with in the middle part of drag lever 1 shaft
Two middle part parallel surfaces, middle part parallel surface has slideway elongated slot；Slip location U it is milled with above valve platen seat 3
Shape groove, groove both wings hinged connection hole, the thickness of the middle part parallel surface of drag lever 1 equals to or slightly less than valve
The width of the location U-lag that slides of platen seat 3；Drag lever 1 and valve platen seat 3 are passed by bolt
In the middle part of slide location U-lag and drag lever 1 shaft above valve platen seat 3, the slideway on parallel surface is long
The hinged through hole of groove is flexibly connected.
The connected mode letter that drag lever 1 and the bolt supporting threaded rod 2 and valve platen seat 3 are movably hinged
Single reliable, low cost, the process-cycle is short, is a kind of connected mode comparing optimization.
When installing valve, platen seat 3 sliding phenomenon occurs for anti-air-stop gate erecting device, also include antiskid lock
Sheet 6, described anti-skidding locking plate 6 center has fastening bolt through hole, drag lever 1 and anti-skidding locking plate 6 to pass through bolt
The slideway elongated slot on parallel surface and the fastening bolt through hole on anti-skidding locking plate 6 in the middle part of drag lever 1 shaft
It is attached.
In conjunction with accompanying drawing 2, concrete assembling and the valve installation process of valve erecting device are described:
1) two platen pillars 4 are inserted respectively in the hole, location on valve platen seat 3 and annular platen 5,
On the premise of ensureing the two disk depth of parallelisms, three is welded, and the welding slag after welding is cleared up；
2) the valve platen seat 3 after welding, platen pillar 4, annular platen 5 parts are utilized valve
U-shaped slide groove on dish seat 3 assembles with drag lever 1, and uses screw bolt and nut standard component to carry out
Connect, it is not necessary to fastening；
3) the anti-skidding locking plate of two panels 6 is installed on two parallel planes of drag lever 1 slide groove so that it is be positioned at
Between valve platen seat 3 and support threaded rod 2, and screw bolt and nut standard component is used to be attached, it is not necessary to
Fastening；
4) it is screwed into supporting threaded rod 2 in the distribution top board collet threaded hole in the plane of cylinder cap top, then will peace
The U supporting threaded rod 2 it is arranged on equipped with valve platen seat 3 parts, the drag lever 1 of anti-skidding locking plate 6 parts
In shape chute, and use screw bolt and nut standard component to be attached, fasten；
5) slide in making valve platen seat 3 parts slideway on drag lever 1, determine valve platen 3
Part and valve to be installed, on a upright position, fasten the screw bolt and nut standard component on valve platen seat 6,
Screw bolt and nut standard component on fastening anti-slip locking plate 6；
6) adjust support threaded rod 2 and be screwed into the degree of depth into cylinder cap top plane distribution top board screwed hole, make support spiral shell
Rasp bar 2 becomes a fulcrum of having an effect of valve erecting device, needs to ensure valve platen seat 3 parts and treat simultaneously
Dress valve contacts also has certain compression travel；
7), after above-mentioned preparation completes, operator A holds drag lever 1 afterbody through " annular knurl " place
The axle journal section managed down pressure drag lever 1, now valve spring and spring holder can produce one therewith and decline row
Journey, along with the annular slot moving down head portion that of spring holder is exposed to outside spring holder, coordinates personnel B subsequently
Being installed in the annular slot of head portion that by two valve collets, locker blocks rear operator A and lifts valve
Depression bar 1, the spring holder after rising i.e. may utilize valve collet under the active force of valve spring and pinned by valve,
The installation process to a valve gear is i.e. completed after removing valve erecting device；
8) for the installation of different head valve devices, the screw thread specification supporting threaded rod 2 afterbody need to only be changed,
Utilize the slideway on drag lever 1 to adjust the position of valve platen seat 3 parts, it is not necessary to again to add simultaneously
Work valve erecting device.
