Abstract
The utility model discloses a mud sediment ball valve belongs to fluid machinery. This mud sediment ball valve includes the valve body, controls the valve gap, sets up the spheroid in the valve body, be provided with the disk seat ripper ring between left side valve gap and the spheroid, disk seat ripper ring and spheroid contact one side are provided with face sealed firmly, and it has the fixed slot of placing soft seal valve base just to open, be provided with a plurality of sealing washers between disk seat ripper ring periphery and the valve gap, be provided with protective gap between disk seat bracing ring terminal surface and the valve gap, be provided with the low reaches sealing washer between spheroid and the right valve gap, the low reaches sealing washer is provided with the sealed face with the spheroid laminating. Adopt the utility model discloses an asymmetric sealed design of upstream and downstream improves the reliability that the ball valve is sealed.
Description
Technical field
The utility model relates to Fluid valve field, specifically a kind of body refuse ball valve.
Background technique
Ball valve extensive use in fluid controls, control in application at fluid, the sealing of valve is even more important.In prior art, valve adopts one seal ring to be sealed usually, and sealing effect is not ideal enough; Repeatedly run at valve, after folding, seal ring easily weares and teares, aging etc., cause sealing effect bad, cause fluid leakage; Meanwhile, in multiple valves of series connection in stream controls, if upstream valve leaks, also can cause certain influence to valve downstream.And particularly relatively severe in operating mode, the more situation of body refuse is easy to occur that ball valve is blocked, or blocks, and cannot open and close normally.
Model utility content
The utility model aims to provide a kind of body refuse ball valve, by the asymmetric Seal Design of upstream and downstream, improves the reliability of ball valve sealing, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of body refuse ball valve, is characterized in that: comprise valve body, left and right valve gap, the spheroid be arranged in valve body; Be provided with valve seat bearing ring between described left valve gap and spheroid, valve seat bearing ring contacts one side and is provided with hard sealing surface with spheroid, and has the fixed groove placing soft seal valve seat; Be provided with multiple seal ring between described valve seat bearing ring circumferential surface and valve gap, between valve seat bracing ring end face and valve gap, be provided with portable protective gaps; Be provided with downstream seal circle between described spheroid and right valve gap, downstream seal circle is provided with the sealing surface of fitting with spheroid.
Further, described downstream seal circle is threaded connection in right valve gap, and is provided with sealing plain cushion between downstream seal circle and right valve gap.
Further, the sealing surface of described downstream seal circle is taper.
Further, valve seat back-up ring has been connected by screw in described valve seat bearing ring.
The beneficial effects of the utility model are: the utility model is by the asymmetric Seal Design of upstream and downstream, the valve seat bearing ring of upstream under pressure, valve seat can be driven to offset to spheroid, kill spheroid, spheroid kills downstream seal circle simultaneously, improves the reliability of ball valve sealing, is particularly applicable to body refuse more, the operating mode of bad environments, the phenomenon such as avoid downstream seal circle stuck.
Accompanying drawing explanation
Fig. 1 is the body refuse ball-valve structure schematic diagram that the utility model provides.
Mark in figure: 1 be spheroid, 2 be valve seat bearing ring, 3 be valve seat, 4 be valve seat back-up ring, 5 be portable protective gaps, 6 be downstream seal circle, 7 be left valve gap, 8 for right valve gap.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of body refuse ball valve, comprises valve body, left and right valve gap 8, the spheroid 1 be arranged in valve body; Be provided with valve seat 3 bearing ring 2 between described left valve gap 7 and spheroid 1, valve seat 3 bearing ring 2 contacts one side and is provided with hard sealing surface with spheroid 1, and has the fixed groove placing soft seal valve seat 3; Be provided with multiple seal ring between described valve seat 3 bearing ring 2 circumferential surface and valve gap, between valve seat 3 bracing ring end face and valve gap, be provided with portable protective gaps 5; Be provided with downstream seal circle 6 between described spheroid 1 and right valve gap 8, downstream seal circle 6 is provided with the sealing surface of fitting with spheroid 1.Described downstream seal circle 6 is threaded connection in right valve gap 8, and is provided with sealing plain cushion between downstream seal circle 6 and right valve gap 8.The sealing surface of described downstream seal circle 6 is taper.Valve seat back-up ring 4 has been connected by screw in described valve seat 3 bearing ring 2.
Before use, soft seal valve seat 3 is positioned in the fixed groove of valve seat 3 bearing ring 2, and valve seat back-up ring 4 is fixed in valve seat 3 bracing ring by socket head screw, valve seat 3 is fixed.In use, when flowing medium is through flowing into ball valve, valve seat 3 bearing ring 2 of upstream is first acted on, valve seat 3 bracing ring, under the pressure effect of flowing medium, moves to spheroid 1, and sealing surface and spheroid 1 is killed, drive spheroid 1 to displaced downstream, final spheroid 1 kills on downstream seal circle 6.The a large amount of body refuses contained in medium fluid can flow away with medium, or the portable protective gaps 5 between valve seat 3 bracing ring end face and valve gap is piled up, and sealing surface does not have the accumulation of body refuse, avoids the phenomenon that downstream is easily stuck, effectively improves the reliability of ball valve.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (4)
