Abstract
The utility model relates to a three-eccentric high-performance sealing butterfly valve, which comprises a vale body and a valve rod. A composite shaft sleeve is sleeved on the periphery of the valve rod, and then the composite shaft sleeve is connected with the inner wall of the valve body in contact mode. The composite shaft sleeve comprises a fixed lubricating bearing arranged inside and a sliding bearing arranged outside. One end of the sliding bearing close to an inner cavity of the valve body is provided with a groove which opens towards the valve rod, an O-shaped sealing ring is placed in the groove, and the sliding bearing is connected with the valve rod in sealing mode through the O-shaped sealing ring. The composite shaft sleeve is sleeved on the valve rod of the butterfly valve, and the O-shaped sealing ring is arranged for sealing, so that media and dusts are not easy to accumulate and block, and no dusts can exist between the valve rod and the composite shaft sleeve. Therefore, the valve rod is not easy to block, and service life of the butterfly valve is prolonged.
Description
Technical field
The utility model relates to a kind of three eccentric high-performance seal butterfly valves.
Background technique
On the valve rod of three eccentric high-performance seal butterfly valves, be with axle sleeve usually, but existing axle sleeve is single axle sleeve, the medium dust is prone to be deposited between axle sleeve and the valve rod, and it is stuck to cause valve rod to be prone to.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of three eccentric high-performance seal butterfly valves are provided, its valve rod is difficult for stuck, prolongs the working life of valve.
The utility model solves the technological scheme that its technical problem adopted: a kind of three eccentric high-performance seal butterfly valves; Have valve body, valve rod; The valve rod periphery is connected with the valve interior wall contact after being with composite shaft sleeve; Described composite shaft sleeve comprises the sliding bearing that is positioned at inner fixedly lubricating bearings and is positioned at the outside, and described sliding bearing has groove near valve inner cavity one end, and slot opening is towards valve rod; Be placed with O-ring seals in the groove, described sliding bearing is connected with valve stem seal through O-ring seals.
The beneficial effect of the utility model is: be with composite shaft sleeve on the valve rod of the utility model; Seal but also be provided with the O RunddichtringO, so the difficult accumulation obstruction of medium dust, keep totally dustless between valve rod and the composite shaft sleeve; Valve rod is difficult for stuck, has prolonged the working life of butterfly valve.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the partial structurtes schematic representation of the utility model;
Wherein: 1. valve body, 2. valve rod, 3. fixing lubricating bearings, 4. sliding bearing, 5.O shape seal ring.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of three eccentric high-performance seal butterfly valves as shown in Figure 1; Have valve body 1, valve rod 2, valve rod 2 peripheries are connected with the contact of valve body 1 inwall after being with composite shaft sleeve, and composite shaft sleeve comprises the sliding bearing 4 that is positioned at inner fixedly lubricating bearings 3 and is positioned at the outside; Sliding bearing 4 has groove near valve body 1 internal cavities one end; Slot opening is placed with O-ring seals 5 towards valve rod 2 in the groove, sliding bearing 4 is tightly connected through O-ring seals 5 and valve rod 2.
Be with composite shaft sleeve on the valve rod 2, seal but also be provided with O RunddichtringO 5, thus the difficult accumulation obstruction of medium dust, keeping totally dustless between valve rod 2 and the composite shaft sleeve, valve rod 2 is difficult for stuck, has prolonged the working life of butterfly valve.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
