Abstract
The utility model discloses a protect eccentric half -ball valve entirely, this hemisphere valve include the valve body and inlay spheroid wherein, and valve body upper portion is equipped with the upper shaft, and the lower part is equipped with down the axle, all is equipped with wear -resisting type self -lubricating shaft sleeve in that the upper shaft is epaxial under and. The utility model provides a protect eccentric half -ball valve entirely axle (upper shaft, lower) and valve body, the spheroid, wear problem between the bottom improves valve life, sealing performance, the big problem of protect eccentric half -ball valve entirely moment of torsion has also been solved simultaneously.
Description
Technical field
This utility model relates to a kind of semisphere valve, specifically eccentric half-ball valve.
Background technology
Ball valve (ball valve) was come out in 20th century, and along with developing rapidly of science and technology, production technology and product structure are not
Disconnected improvement, in short time decades, has developed rapidly and has become a kind of main valve class.In western industrial prosperity state
Family, the use ratio of ball valve rises the most year by year, and in China, it is defeated that ball valve is widely used in petroleum refining, distance
Send the industries such as pipeline, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, national economy is occupied act foot
The status of weight.
Eccentric half-ball valve and gate valve are the valves belonging to a type together, and difference is that its closure member is a spheroid, spheroid around
Valve body centrage rotates, and reaches to open, close a kind of valve of purpose.Ball valve is mainly used in pipeline
Make the flow direction cutting off, distribute and changing medium.Two-chip type ball valve, three-flat ball valve, is to be widely used in recent years
Valve.Eccentric half-ball valve is the ball valve classification of a kind of modern, and it has some superioritys that self structure is exclusive,
As little, lightweight in simple in construction, volume.It is widely used in sewage disposal, paper pulp, aluminium oxide, urban heating heat supply etc.
Need tight airtight occasion；It is applicable to power plant, water sluice or the control of gaseous state conveyance conduit.Domestic existing semisphere valve
The ratio that weares and teares between bottom and axle, valve body and axle is more serious, and valve opening and closing moment of torsion is big, after repeatedly opening and closing, arises that spheroid
Sagging, the gap between axle and spheroid, valve body increases, and ultimately results in valve leak.
Utility model content
Utility model purpose: in order to overcome the deficiencies in the prior art, this utility model provides a kind of wear-resisting, use
Life-span length and the high full protection eccentric half-ball valve of safety.
For solving above-mentioned technical problem, the technical solution of the utility model is a kind of full protection eccentric half-ball valve, including valve body
With inlay spheroid therein, valve body top is provided with upper shaft, and bottom is provided with lower axle, is equipped with wear-resisting type in upper shaft and lower axle
Self lubrication bearing.
Described upper shaft is provided with positioner.
Described positioner be positioning boss or location breathe out not overlap.
It is spherical structure bottom described lower axle.
It is provided with alloy wear-resisting layer between described spheroid and lower axle.
Described body base is furnished with bottom, is provided with alloy wear-resisting layer inside bottom.
Valve body side is furnished with sealing ring, and sealing ring top is provided with trim ring, and sealing ring is fixed on valve body by trim ring.
To be solved in the utility model be serious wear between semisphere valve bottom and axle, valve body and axle, valve opening and closing moment of torsion big,
After repeatedly opening and closing, arise that spheroid gap sagging, between axle and spheroid, valve body increases, ultimately result in valve leak
Etc. problem.
Beneficial effect: this utility model solves full protection eccentric semi-spherical valve shaft (upper shaft, lower axle) and valve body, spheroid,
Wear problem between bottom, improves valve service life, sealing property；Also solve full protection eccentric half-ball valve to turn round simultaneously
The problem that square is big.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
Embodiment one: as it is shown in figure 1, full protection semisphere valve includes that valve body 1 and spheroid 3, valve body 1 top are provided with upper shaft
8, upper shaft 8 is provided with positioning boss 12, and valve body 1 bottom is provided with lower axle 9, and lower axle 9 bottom design is ball shape structure；On
It is equipped with wear-resisting type self lubrication bearing 5 on axle 8 and lower axle 9；It is provided with alloy wear-resisting layer between spheroid 3 bottom and lower axle 9
11, it is furnished with bottom 10 bottom valve body 1, bottom 10 is fixing with valve body 1 to be connected, and is provided with alloy wear-resisting layer inside bottom 10
11.Valve body 1 side is furnished with sealing ring 4, and sealing ring 4 top is provided with trim ring 2, and trim ring 2 is fixing with valve body 1 to be connected,
And sealing ring 4 is had certain compression.Valve body is furnished with support 6, and support 6 is installed driving head 7.
Embodiment two: essentially identical with embodiment one, the positioner that institute's difference is in upper shaft 8 is breathed out not for location
Set.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
