Description
Technical field
The present invention relates to a kind of metal bellows ball valves, belong to the technical field of ball valve.
Background technology
Metal bellows has a wide range of applications, bellows mechanism will as elastic sealing elements in valve manufacture industry
Dynamic sealing of the valve rod at stuffing-box is converted to static seal of the valve rod at valve deck, and the sealing for making valve is more safe and reliable, but
It is that since metal bellows can only bear to stretch and compress, and torque cannot be born.
Ball valve (ball valve) come out in the 1950s, with science and technology rapid development, production technology and
Product structure is continuously improved, and in the 40 short years, has been rapidly developed as a kind of main valve class.In western industrial
Flourishing country, the use of ball valve is continuous year by year to be risen.
In China, ball valve be widely used petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power,
The industries such as municipal administration, steel occupy very important status in national economy.It has the action being rotated by 90 °, and faucet body is
Sphere has circular through hole or channel to pass through its axis.
Ball valve is mainly used to make the flow direction for cutting off, distributing and changing medium in pipeline, it is only needed with rotation 90
The operation of degree and the rotating torque of very little can just close tight.Ball valve optimum switchs, stop valve uses, V-type ball valve.It is electronic
Valve still should be specifically noted that its environmental condition used, due to the electric device in electrically operated valve in addition to it should be noted that pipe parameter
It is an electromechanical equipment, use state is influenced very big by its use environment.Under usual state, electrical ball valve, butterfly valve are in following ring
Border is using will pay special attention to.
Invention content
Goal of the invention：The technical issues of present invention sealing effect of being solved is poor, the present invention provide a kind of metal bellows
Ball valve.
Process program：A kind of metal bellows ball valve, including sealing bracing ring, finger, thrust bearing, axle sleeve, bellows,
Valve rod, valve deck, stop pin, stent, filler pressing sleeve, electric device, cam sleeve, valve body, sphere, bearing, fixing axle, sealing ring,
The valve body is connect by bellows with valve deck, the body base centre position and fixed axis connection, the fixing axle and axis
Connection is held, sphere is equipped in the valve body, the sphere both sides are connect with sealing ring, and the sealing ring connects with sealing bracing ring
It connects, valve rod is equipped with above the sphere, the stem bottom is connect with axle sleeve, and the axle sleeve is connect with thrust bearing, described to stop
Thrust bearing is connect with finger, and the valve rod is connect with cam sleeve, and the cam sleeve connect with stent and fixed by stop pin, described
Stent is connect with filler pressing sleeve, and the valve stem top is connect with electric device.
Further, the bellows is metal bellows.
Further, the stem diameter 50mm.
Further, described pull pin can be rotated by 360 °.
The present invention is suitable for often operation, and keying is rapid, light, and fluid resistance is small, simple in structure, and relative volume is small, weight
Amount is light, and easy to repair, good seal performance is not limited by installation direction, and the flow direction of medium can be arbitrary, and without friction, noise is small
