Abstract
The present invention is a kind of pneumatic cut-out bellows valve, including valve rod, valve deck, it is fixedly connected with flap with the lower end of the valve rod, the pneumatic cut-out bellows valve further includes stuffing-box, stuffing-box gasket, compression type bellows, filler group, the compression type bellows and the valve rod are concentric, and the upper and lower ends of the compression type bellows are abutted with the stuffing-box gasket.Beneficial effects of the present invention are as follows：It is replaced convenient for the repair of bellows, extends the service life of this equipment.
Description
Technical field
The present invention relates to valves, and in particular to a kind of pneumatic cut-out bellows valve.
Background technology
Existing technology has the following problems：In processing technology, there are weld seam after bellows and valve deck welding and welding,
Because bellows has service life, reach defined access times, bellows will damage, and when bellows has damage, need
Bellows and valve deck are carried out physics cutting can just to replace bellows.
Invention content
The present invention provides a kind of pneumatic cut-out bellows valve, the purpose for designing and developing the present apparatus is：Convenient for bellows
Repair replace, extend the service life of this equipment.
The present invention provides following technical proposals：A kind of pneumatic cut-out bellows valve, including valve rod 1, valve deck 2, and it is described
The lower end of valve rod 1 is fixedly connected with flap 3, which is characterized in that the pneumatic cut-out bellows valve further includes stuffing-box 4, filler
Letter gasket 5, compression type bellows 6, filler group 7, the compression type bellows 6 is concentric with the valve rod 1, the compression type wave
The upper and lower ends of line pipe 6 are abutted with the stuffing-box gasket 5, and the valve deck 2 and the valve rod 1, compression type bellows 6 are coaxial
The heart, the valve rod 1, compression type bellows 6 are placed in the valve deck 2, and the stuffing-box gasket 5 is crimped with the stuffing-box 4, institute
The lower section connection valve body 8 of valve deck 2 is stated, the stuffing-box gasket 5 is rabbeted with the flange 9 that crimps.
Beneficial effects of the present invention are as follows：Modified pneumatic cut-out bellows valve structure, increases stuffing-box, bellows
Upper flange structural adjustment, characteristic comparing：Bellows upper end crimping flange 9 originally and valve deck type of attachment are welding structure,
Improved type of attachment is fastenedly connected for bolt, as shown in the figure.It is sealed by spirotallic gasket between bellows and valve deck.
In processing technology, the flat process of weld seam vehicle after cancelling bellows and valve deck welding and welding, to reduce the processing of valve deck
Cost bellows and valve deck are sealed with spirotallic gasket, because bellows has service life, reach defined access times, bellows is just
Can damage, when bellows has damage, need not with bellows and valve deck are carried out physics cutting as before, it is only necessary to
Connection bolt is unclamped, taking-up.It is replaced convenient for the repair of bellows, extends the service life of this equipment.
Description of the drawings
Fig. 1 is the improved structural schematic diagram of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
Fig. 1：Valve rod 1, valve deck 2, flap 3, stuffing-box 4, stuffing-box gasket 5, compression type bellows 6, filler group 7, valve body
8, flange 9 is crimped.
A kind of pneumatic cut-out bellows valve, including valve rod 1, valve deck 2, flap is fixedly connected with the lower end of the valve rod 1
3, the pneumatic cut-out bellows valve further includes stuffing-box 4, stuffing-box gasket 5, compression type bellows 6, filler group 7, the pressure
Compact form bellows 6 and the valve rod 1 are concentric, and the upper and lower ends of the compression type bellows 6 are supported with the stuffing-box gasket 5
It connects, the valve deck 2 and the valve rod 1, compression type bellows 6 are concentric, and the valve rod 1, compression type bellows 6 are placed in the valve
In lid 2, the stuffing-box gasket 5 is crimped with the stuffing-box 4, and the lower section of the valve deck 2 connects valve body 8, the stuffing-box pad
Piece 5 is rabbeted with the flange 9 that crimps.
Modified pneumatic cut-out bellows valve structure, increases stuffing-box 4, and the upper flange structural adjustment of bellows is special
Point compares：Bellows upper end originally is welding structure with valve deck type of attachment, and improved type of attachment is that bolt fastening connects
It connects, is sealed by spirotallic gasket between bellows and valve deck.In processing technology, cancel bellows and valve deck welding and welding
Afterwards the flat process of weld seam vehicle, processing cost bellows and valve deck to reduce valve deck are sealed with spirotallic gasket, because of ripple
Pipe has service life, reaches defined access times, and bellows will damage, need not be with when bellows has damage
Bellows and valve deck are carried out physics cutting as before, it is only necessary to connection bolt be unclamped, taking-up.
