Abstract
The invention belongs to a kind of ball valve, and in particular to a kind of ball valve with magnetic tape trailer flutter valve seat.It includes valve body, the side of valve body has been bolted side valve lid and by forming pressure boundary, the interior of valve body is provided with spheroid, spheroid is provided with cavity, the cavity communicates with another side runner on the side runner and side valve body on valve body, one end of spheroid is connected with valve rod, and for the other end with pivotally connected, the outside of spheroid is provided with valve seat.Its advantage is 1) valve seat carries baffle empennage, ensure that runner does not connect directly with lumen during valve opening；Fully open position is reached in valve, ensures that the medium in spheroid not directly enters lumen；2) stopper slot is provided with valve body, prevents valve seat from rotating loss of function.
Description
Technical field
The invention belongs to a kind of ball valve, and in particular to a kind of ball valve with magnetic tape trailer flutter valve seat.
Background technology
The great advantage of ball valve is exactly that runner is totally straight after opening, and flow resistance is extremely low, pressure loss very little, corresponding driving
The pump power can reduction of media flow is a lot.Usage amount is increasing under overall situation green at present, and face is also
Come wider.The common structure of ball valve includes：Float ball valve and Fixed ball valve.Float ball valve is generally used for small-bore, low
Pressure difference；Fixed ball valve is generally used for heavy caliber, High Pressure Difference.As new device scale is increasing, parameter more and more higher, Gu
Determine ball valve have developed rapidly.
Fixing ball valve is used and popularized in gas, liquid medium operating mode, quite ripe, but in such as coal chemical industry, polysilicon
Deng the operating mode containing a large amount of solid granulates then using not ideal.Because ball valve will be rotated by 90 ° in opening process, only
Fully open position can close lumen, and when part is opened, lumen directly connects with runner, and a large amount of solid granulates enter lumen and deposited,
Pivot can be caused to kill.If medium also contains easy coking component, valve can be caused to lose operational capacity faster.
The content of the invention
It is an object of the invention to provide a kind of not through ball valve of lumen, and it, which has, prevents solid granulates medium from entering lumen
The characteristics of causing pivot to kill.
The present invention is achieved in that the not through ball valve of lumen, and it includes valve body, and the side of valve body is bolted
There is side valve lid and by forming pressure boundary, the interior of valve body is provided with spheroid, and spheroid is provided with cavity, the cavity and the side on valve body
Another side runner on runner and side valve body communicates, and one end of spheroid is connected with valve rod, and the other end is with pivotally connected, outside spheroid
Portion is provided with valve seat.
Stopper slot is provided with described valve body and side valve body, can ensure that lumen is got along well a side runner, another effluent all the time
Road, sphere cavity directly connect, and prevent solid granulates from entering lumen easily.
There is the hemispherical cavity formed between described valve body and spheroid.
The edge of described valve seat carries baffle empennage, and empennage obtains continuous sphere sealing strip by processing.
It is an advantage of the invention that 1) valve seat carries baffle empennage, ensure that runner and lumen be not straight during valve opening
Lead in succession；Fully open position is reached in valve, ensures that the medium in spheroid not directly enters lumen；2) stopper slot is provided with valve body,
Prevent valve seat from rotating loss of function.
Brief description of the drawings
Fig. 1 is the not through ball valve fully open position structure chart of lumen provided by the present invention；
Fig. 2 is that the not through ball valve closed positions of lumen provided by the present invention seal schematic diagram；
Fig. 3 is valve seat construction figure.
In figure：1 valve body, 2 valve seats, 3 pivots, 4 spheroids, 5 valve rods, 6 bolts, 7 side valve bodies, 8 one side runners, 9 lumens, 10 limits
Position groove, 11 sphere cavities, 12 another side runners, 13 continuous sphere sealing strips, 14 empennages.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and examples：
As Figure 1-3, the not through ball valve of lumen includes the valve body 1 of hollow structure, and the side of valve body 1 passes through bolt 6
It is connected with side valve lid 7 and by forming pressure boundary.The inside of valve body 1 is provided with spheroid 4, also tangible between valve body 1 and spheroid 4
Into hemispherical cavity 11, spheroid 4 is provided with cavity, the cavity and another effluent on the side runner 8 and side valve body 7 on valve body 1
Road communicates, and one end of spheroid 4 is connected with valve rod 5, and the other end is connected with pivot 3, and supports work revolution fortune by valve rod 5 and pivot 3
It is dynamic, in full-gear as ordinary ball valve.The outside of spheroid 4 is cased with valve seat 2, and the edge of valve seat 2 carries baffle empennage 14, tail
The wing 14 obtains continuous sphere sealing strip 13 by processing, and a ball valve has two such valve seats, axial symmetry arrangement.Valve body 1
Ensure that lumen 2 is got along well an effluent all the time with 10 such valve of stopper slot in closing process (Fig. 2) is provided with side valve body 7
Road 8, another side runner 12, the inner chamber of spheroid 4 directly connect, and prevent solid granulates from entering lumen easily.During valve opening
Ensure that runner does not connect directly with lumen；Fully open position is reached in valve, ensures that the medium in spheroid not directly enters lumen.
(Fig. 2).
Valve seat when ordinary ball valve is closed can not block the inner chamber both ends on spheroid in real time.The not through ball valve of lumen has
Unique valve seat (Fig. 3) with empennage, the valve seat are to increase empennage 2 at the edge of valve body 1.Valve seat in the present invention does not allow
Rotated freely as ordinary ball valve valve seat, so being provided with stopper slot 3 on valve body and side valve body.
