Description
Technical field
The utility model is related to connect valve body field, specifically a kind of bellows connects valve body.
Background technology
Bellows stop valve is also sylphon seal shut-off valve, is welded by automatic seam-welding, fluid media (medium) and air it
Between form a metallic barrier, it is ensured that the design of valve rod zero leakage uses bellows structure, stainless steel inside bellows stop valve
Bellows lower end be welded on valve rod, to prevent process fluid etch valve rod.The other end is placed between valve body and valve deck and constitutes
Static seal.If can also avoid leaking using dual Seal Design ripple tube failure valve stem packing, bellows is welded in valve rod holding
Stable runnability avoids causing valve rod to vibrate due to valve plug vibration.It is best suited for steam, inflammable, explosive, conduction oil, height
On the pipeline of the media such as purity, toxic.
There are many shortcomings for a kind of bellows connection valve body of current stage, for example, stability is poor, it can not be right
Pressure capacity is adjusted.
Utility model content
The purpose of this utility model is to provide a kind of bellowss to connect valve body, to solve stability in the prior art
Difference, the problem of pressure capacity can not be adjusted.
To achieve the above object, the utility model provides the following technical solutions：A kind of bellows connection valve body, including valve

Inside is equipped with bellows, and the top of the valve deck is equipped with mounting plate, valve rod socket is provided at the top of the mounting plate,
Valve rod is installed on the valve rod socket, fixed plate, the down either side installation of the fixed plate are installed on the valve rod
There are supporting rod, the top of the valve rod that adjusting handle is installed.
Preferably, the top of the valve rod and the top of bellows connect, and the bottom end of bellows is equipped with valve plate.
Preferably, air bag and steel ring are installed, and air bag and steel ring are alternately installed on the bellows.
Preferably, be provided with screw thread on the valve rod, and the middle position of fixed plate is provided with threaded hole, and valve rod with
Threaded hole is connected by screw rod transmission.
Compared with prior art, the utility model has the beneficial effects that：The bottom end of the valve rod of the utility model is equipped with wave
Line pipe can protect valve rod by bellows, can be corroded to avoid valve rod, increase its service life, and bellows
It is composed by air bag and steel ring, there is certain elasticity, the vibration of valve body can be reduced, and wave can be controlled by valve rod
Line pipe compresses, and adjusts the anti-pressure ability of bellows, increases the functionality of device.
