Abstract
The invention relates to an expansion ball valve with sealing rings. The expansion ball valve comprises a valve stem, a ball, the sealing rings, two expansion devices, expansion driving devices, a valve and a valve stem driving device. The ball is slidably or movably arranged on the valve and is connected with one end of the valve stem, and the other end of the valve stem is connected with the valve stem driving device; the expansion devices are slidably arranged on the valve under the control of the expansion driving devices; the expansion driving devices comprise worm and worm gear pairs; the two expansion devices are respectively arranged on two sides of a ball separating pipeline; the sealing rings are movably arranged on the expansion devices. Compared with the prior art, the expansion ball valve has the advantages of stability in sealing performance, long service life and low running cost.
Description
Technical field
The present invention relates to a kind of ball valve, particularly relate to a kind of telescopic ball valve of seal ring being convenient to safeguard.
Background technique
In recent years, in the application of ball valve technology in industrial automation, development rapidly, the industries such as petrochemical industry, Coal Chemical Industry, coal liquefaction, aluminium oxide, chemical fertilizer, oil, rock gas, paper industry, core work, power station, boats and ships, metallurgy, heavy machinery, scientific research institutions are widely used in, especially, in high temperature, high-pressure liquid pipeline system control, very important key effect is served.Because of existing ball valve be applied in high temperature, high pressure pipe line Systematical control time, sealing effect is unstable, seal failure fast, difficult in maintenance, and steering force is large, and use middle replacing frequent, operating cost is high.One of current anxious equipment to be modified.Up to now, there is no sealability more stable, safeguard more convenient, and significantly can reduce the ideal product of operating cost.
Summary of the invention
The present invention is directed to above-mentioned present situation, through carefulness development and repetition test, design the telescopic ball valve of a kind of seal ring, solve sealability in prior art unstable, safeguard inconvenient, the difficult problem that operating cost is high.
Technological scheme of the present invention is as follows:
Comprise valve rod, valve body, spheroid, seal ring, expansion device, retractable driving device, valve rod driving device, spheroid slides or is movably arranged in valve body, and spheroid is connected with one end of valve rod, and the other end of valve rod is connected with drive unit; Seal ring is movably arranged on expansion device, and expansion device is slidably arranged on valve body by retractable driving device.
Advantageous effect of the present invention is as follows:
1, seal ring that is for convenience detach, that change is provided with, when seal ring is worn to when can not normally use,
Replacing spare part can be pulled down.
2, expansion device is provided with, seal ring is movably arranged on expansion device, when opening or close ball valve, expansion device is first with seal ring to move axially along pipeline by retractable driving device, leave ball seal face, after adjust the working position of spheroid through valve rod by valve rod driving device, when guaranteeing the whole position of spheroid tune work not only easily but also can not seal ring be abraded; After spheroid adjustment position completes, expansion device band seal ring moves axially along pipeline by retractable driving device, is pressed on by seal ring on ball seal face.
3, sealability is stablized, and operating cost is low.Life-span is long, easy to maintenance.
