Abstract
The utility model is to solve the problem of failed sealing of sealing materials during application of globe valve and provides a bellows seal globe valve. The valve includes a bellows seal component at the upper part of the valve cover of the globe valve and is achieved by inserting the protruding part of the bellows seal component to the bearing inner hole for positioning; adopting a bellows seal as the middle section of the bellows seal component; welding the lower positioning disc of the bellows seal component on the check port of the valve cover while holding a bent valve rod in the bellows seal; inserting the upper end of the bent valve rod into hole on the protruding part of the bellows seal; and inserting the lower end of the bent valve rod into the valve cover hole. The utility model has no leakage during application and can be installed on toxic/pollutant gas/liquid medium pipelines.
Description
Technical field
The utility model relates to ball valve, and more particularly, the utility model relates to a kind of bellows ball valve.
Background technique
The existing main component part of ball-valve structure has valve body, valve gap, sealing seat, ball sealer, valve rod, stem packing, hold-down grid, fastening piece, bolt, nut and opens and closes handle etc.The ball sealer that has through hole is installed in the valve body, the flange that has sealing seat is fixed on the valve body by screw bolt and nut, the valve rod lower end is passed the valve body mesopore and is linked to each other with ball sealer, between valve body mesopore and the valve rod stuffing box packing is housed, and compresses filler by fastening piece, stop the interior medium of valve to leak in the atmosphere from stem packing by hold-down grid, revolution opens and closes handle, drive ball sealer and do 90 ° of revolutions, make through hole and valve hole dislocation on the ball sealer cut off passage for 90 °, stop medium circulation in the valve.The defective of ball valve maximum is to use in the process because friction, and the stem packing sealing effect lost efficacy, and medium can leak in the atmosphere in the valve, thus ball valve be under an embargo be installed in poisonous, have on the pipeline of dusty gas, liquid medium.
Summary of the invention
The purpose of this utility model is to solve in the ball valve using process in the technical problem of stem packing place seal failure, and a kind of bellows ball valve is provided.
The concrete technological scheme of the utility model is as follows: increase by a cover bellows component on ball valve top, structure is as follows: the bellows component convex portion inserts the brearing bore location, the bellows component stage casing is a bellows, bellows component lower end positioning disk is welded on the valve gap seam, the wryneck valve rod is in bellows, insert in the bellows component projection hole its upper end, and insert in the valve cover hole its lower end.
The utlity model has outstanding advantage and be not have external leakage in the using process, can be installed on the gas poisonous, that pollution is arranged, the liquid medium pipeline.
Description of drawings
Fig. 1 is the bellows ball valve erection drawing
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail
Among Fig. 1, switch knob 1 is inserted sleeve pipe 2, sleeve pipe 2 passes through key 3 to eccentric solid of rotation 4 transmitting torques, eccentric solid of rotation 4 is installed in the centering sleeve 5 and does rotation motion, capacity eccentric bearing 6 is installed in the eccentric opening of eccentric solid of rotation 4, bellows component convex portion 7 inserts capacity eccentric bearing 6 endoporus location, bellows component lower end positioning disk 9 is welded on valve gap 10 seams, also insert in bellows component convex portion 7 holes wryneck valve rod 8 upper ends, insert in valve gap 10 holes wryneck valve rod 8 lower ends, link to each other with ball sealer 11, valve gap 10 is equipped with stuffing box packing 15 with wryneck valve rod 8, and centering sleeve 5 also is fixed on the valve gap 10, and valve gap 10 is fixed on the valve body 13 by fastening piece, ball sealer 11 is installed in the valve body 13, and valve body 13 lower ends install and fix seat 14 and play fixed valve body 13.On two flanges 12 sealing seat 17 is installed respectively, flange 12 is fixed on the valve body 13 by fastening piece 16,18 again, and sealing seat 17 is to be pressed against by the pressure spring effect to reach the sealing medium effect on the sealed spheroid 11.Sealing seat 17, fixed base 14, flange 12 and valve gap 10 all are to adopt fixed " 0 " type rubber seal with the sealing between the valve body 13.
When switch knob 1 drives in 90 ° of processes of eccentric solid of rotation 4 rotation processes, capacity eccentric bearing 6 on the eccentric solid of rotation 4, will stir wryneck valve rod 8 rotates, because bellows component lower end positioning disk 9 is welded on valve gap 10 seams and can not turns round, therefore bellows component is with the differential seat angle between the eccentric solid of rotation 4, revolution by capacity eccentric bearing 6 is compensated, and bellows component plays metamorphosiss such as 90 ° of directions are reversed, drawn, pressure.Because the bellows component upper and lower end all seals with the external world, the inner confined space that forms, even stuffing box packing 15 has leakage, leaking medium is also sealed by bellows component, can not leak in the atmosphere.
Claims (4)
1 one kinds of bellows ball valves, main component part valve body, valve gap, sealing seat, ball sealer, valve rod, stuffing box packing, hold-down grid, fastening piece, bolt, nut and switching handle is characterized in that, increase by a cover bellows component on the valve gap top of ball valve.
2 according to the described ball valve of claim 1, it is characterized in that, bellows component is made of bellows component convex portion, bellows and bellows component lower end positioning disk.
3 according to claim 1 or 2 described ball valves, it is characterized in that, the bellows component convex portion inserts the brearing bore location, and the bellows component stage casing is a bellows, and bellows component lower end positioning disk is welded on the valve gap seam,
