Abstract
The invention belongs to a kind of ball valve, be specifically related to a kind of ball valve with magnetic tape trailer flutter valve seat.It comprises valve body, the side of valve body has been bolted side valve lid and by mineralization pressure border, spheroid is provided with in valve body, spheroid has cavity, this cavity communicates with the side runner on valve body and the opposite side runner on side valve body, one end of spheroid is connected with valve rod, the other end and pivotally connected, and the outside of spheroid is provided with valve seat.Its advantage is, 1) valve seat is with baffle empennage, in valve opening process, ensure that runner is not directly communicated with lumen; Arrive fully open position at valve, ensure that the medium in spheroid does not directly enter lumen; 2) valve body has restraining groove, prevent valve seat from rotating loss of function.
Description
Technical field
The invention belongs to a kind of ball valve, be specifically related to a kind of ball valve with magnetic tape trailer flutter valve seat.
Background technique
It is completely straight that the great advantage of ball valve opens rear runner exactly, and flow resistance is extremely low, and the pressure loss is very little, and the pump power of corresponding driven medium flowing just can reduce a lot.Under the overall situation of current environmental protection, use amount is increasing, and face is also come wider.The common structure of ball valve comprises: Float ball valve and Fixed ball valve.Float ball valve is generally used for small-bore, low voltage difference; Fixed ball valve is generally used for heavy caliber, High Pressure Difference.Along with new device scale is increasing, parameter is more and more higher, fixing ball valve development is very fast.
Fixing ball valve uses popularize in gas, liquid medium operating mode, quite ripe, but then uses not ideal at such as Coal Chemical Industry, polysilicon etc. containing the operating mode of a large amount of solid granulates.This is because ball valve wants 90-degree rotation in opening process, only have fully open position to close lumen, when part is opened, lumen is directly communicated with runner, and a large amount of solid granulates enters lumen and deposits, and pivot can be caused to kill.If medium also containing easy coking component, can cause valve to lose operational capacity faster.
Summary of the invention
The object of this invention is to provide the not through ball valve of a kind of lumen, it has the advantages that to prevent from solid granulates medium from entering lumen causing pivot to kill.
The present invention realizes like this, the not through ball valve of lumen, it comprises valve body, the side of valve body has been bolted side valve lid and by mineralization pressure border, has been provided with spheroid in valve body, and spheroid has cavity, this cavity communicates with the side runner on valve body and the opposite side runner on side valve body, one end of spheroid is connected with valve rod, the other end and pivotally connected, and the outside of spheroid is provided with valve seat.
Described valve body and side valve body have restraining groove, can ensure that get along well an all the time side runner, opposite side runner, sphere cavity of lumen is directly communicated with, stop solid granulates to enter lumen easily.
The hemispherical cavity formed in addition between described valve body and spheroid.
The edge of described valve seat is with baffle empennage, and empennage obtains continuous print sphere sealing strip by processing.
Advantage of the present invention is, 1) valve seat is with baffle empennage, in valve opening process, ensure that runner is not directly communicated with lumen; Arrive fully open position at valve, ensure that the medium in spheroid does not directly enter lumen; 2) valve body has restraining groove, prevent valve seat from rotating loss of function.
Accompanying drawing explanation
Fig. 1 is lumen provided by the present invention not through ball valve fully open position structural drawing;
Fig. 2 is lumen provided by the present invention not through ball valve closed positions sealing 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 restraining grooves, 11 sphere cavities, 12 opposite side runners, 13 continuous print sphere sealing strips, 14 empennages.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As Figure 1-3, the not through ball valve of lumen comprises the valve body 1 of hollow structure, and the side of valve body 1 is connected with side valve lid 7 by bolt 6 and by mineralization pressure border.The inside of valve body 1 is provided with spheroid 4, the hemispherical cavity 11 formed in addition between valve body 1 and spheroid 4, spheroid 4 has cavity, this cavity communicates with the side runner 8 on valve body 1 and the opposite side runner on side valve body 7, one end of spheroid 4 is connected with valve rod 5, the other end is connected with pivot 3, and does rotation motion by valve rod 5 and pivot 3 support, the same with ordinary ball valve in full-gear.The outer cover of spheroid 4 has valve seat 2, and the edge of valve seat 2 is with baffle empennage 14, and empennage 14 obtains continuous print sphere sealing strip 13, ball valve by processing two such valve seats, and axisymmetric is arranged.Valve body 1 with side valve body 7 has restraining groove 10 like this valve in closing process (Fig. 2) just can ensure that get along well an all the time side runner 8, opposite side runner 12, spheroid 4 inner chamber of lumen 2 is directly communicated with, prevention solid granulates enters lumen easily.In valve opening process, ensure that runner is not directly communicated with lumen; Arrive fully open position at valve, ensure that the medium in spheroid does not directly enter lumen.(Fig. 2).
Valve seat when ordinary ball valve is closed cannot block the inner chamber two ends on spheroid in real time.The not through ball valve of lumen has the valve seat (Fig. 3) of unique band empennage, and this valve seat increases empennage 2 at the edge of valve body 1.Valve seat in the present invention does not allow to rotate freely as ordinary ball valve valve seat, so have restraining groove 3 on valve body and side valve body.
Claims (4)
1. the not through ball valve of lumen, it is characterized in that: it comprises valve body (1), the side of valve body (1) is connected with side valve lid (7) by bolt (6) and passes through mineralization pressure border, spheroid (4) is provided with in valve body (1), spheroid (4) has cavity, this cavity communicates with the side runner (8) on valve body (1) and the opposite side runner (12) on side valve body (7), one end of spheroid (4) is connected with valve rod (5), the other end is connected with pivot (3), the outside of spheroid (4) is provided with valve seat (2).
