Abstract
The utility model discloses a non-wear spherical cindervalve which structurally comprises a valve body and a valve cover. The valve body is connected with the valve cover through a gasket in an airtight way; a semispherical ball body is arranged inside a spherical inner cavity of the valve body; the spherical surface of the ball body faces the directions of the valve cover, and the upper end and the lower end of the ball body are connected on a valve rod which contacts with the valve body through a sliding bearing; the upper end of the valve rod is connected with a driving device outside the valve body; and a lower shaft cup is arranged below the sliding bearing of the valve rod at the bottom of the valve body. The non-wear spherical cindervalve can withstand scouring of high-speed air current and is low in fault rate and convenient to maintain. The service life of the old spherical cindervalve is only 3months, while, the service life of the novel non-wear spherical cindervalve can reach 12months. The non-wear spherical cindervalve has no leakage and can not be chocked by dust which causes unsmooth operation, thus filling the market vacancy.
Description
Technical field
The utility model relates to a kind of Unloading ball valve, especially a kind of nothing wearing and tearing Unloading ball valve.
Background technique
The metallurgical coal gas pressurizing point and the blast furnace dry method dust settling pocket technique of prior art, remarkable with its energy-saving effect, reliable characteristics, promptly developed.Along with the development of blast furnace dry method dust settling pocket technique, the combination property of valve is also had higher requirement.The tradition Unloading ball valve is the friction type sealing, so it is too big to wear and tear, makes have only 3 months working life, and the maintenance loss that stops production in the work is very big, safeguards inconvenience, and faults such as leakage take place easily.Also may cause appearance to be blocked up and cause the defective that runs improperly by the dust card.
The model utility content
(1) technical problem that will solve
Technical problem to be solved in the utility model provides at the existing in prior technology defective does not have the wearing and tearing Unloading ball valve, has solved short, the easy leakage of prior art ball valve life-span, maintenance cost height, the severe defective of wearing and tearing.Different with traditional Unloading ball valve is that not having wearing and tearing Unloading ball valve characteristics is that sphere and sealing do not have friction, is to adopt sealing seat to stretch to finish sealability.Sealing seat can stretch out automatically and be close on the sphere when the valve pass puts in place.Sealing seat can automatic indentation leave sphere when valve open.Sphere is not opened and closed in having friction, and sealing seat utilizes source of the gas and person's hydraulic system to finish the work.Source of the gas, hydraulic work is switched by electromagnetic valve, and changeover program control is controlled through the circuitry in the electric control box.Can use manually-operable during power failure, sealing seat can automatically reply, and selects for use electronicly must have source of the gas in the scene, with person's hydraulic pipe line.
(2) technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: do not have the wearing and tearing Unloading ball valve, its structure comprises valve body, valve gap, described valve body is connected by gasket seal with valve gap, be provided with the hemisphere spheroid in the spherical inner chamber of described valve body, described spherical ball face is towards the valve gap direction, the two ends up and down of spheroid then are connected on the valve rod, described valve rod contacts with valve body by sliding bearing, the valve rod upper end is connected with the drive unit of valve body outside, is provided with shaft-cup down below the sliding bearing of the valve rod bottom valve body.
Described drive unit can be for electronic or surge or pneumatic.
The ball seal mouth place of described valve gap inwall and valve inner is provided with cylinder, by the sealing of O type circle, also is provided with packing holder, seal ring and spring between described valve gap and the spheroid between described cylinder and the valve gap; Described cylinder is provided with suction port and relief opening.
Described valve rod and contacting point, valve body upper end also are provided with filler and support, and described support is fixed on the valve body by Gland.
(3) nothing wearing and tearing Unloading ball valve of the present utility model compared with prior art has following beneficial effect:
This valve is used in the usefulness of doing control in the conveying releasing system of dried materials such as containing coal gas dust, smoke dust, coal dust, cement.Be applicable to the occasion of telecontrol.The utility model does not have the wearing and tearing Unloading ball valve, and anti-high velocity air washes away, and rate of fault is low, superperformance easy to maintenance, and the Unloading ball valve in past has only 3 months working life, and novel nothing wearing and tearing Unloading ball valve can reach more than 12 months working life.Get rid of the maintenance loss that stops production at work, for the user has improved productivity, this series does not have the reliable cut-out equipment that the wearing and tearing Unloading ball valve can be used as coal gas, its leakage rate is zero, this is that a kind of update product of old structure Unloading ball valve has operation rapidly, characteristics can be used at 250 ℃-300 ℃ long-term easily, and being blocked up by the dust card and causing situation about running improperly to augment the market vacancy can not appear in this nothing wearing and tearing Unloading ball valve.
