Abstract

The utility model discloses an elastic, metal, concentric, high temperature, sealing ball valve, comprising a valve body, a supporting valve pedestal, a ball body, and a valve rod. Wherein, the valve body consists of body of the valve and the connecting body and the triangular taper sealing pad exist between the two above mentioned components. The gap formed by the valve rod and the valve body is filled with the compound stuffing, and the bracket platform that is connected with the valve body is positioned on the upper end of the valve rod. The interior head face of the connecting body constitutes of a valve pedestal. The utility model can be used in the high temperature, high pressure and worn medium, and has better sealability.

Description

Flexibility concentric high temperature metal seal ball valve
Technical field
The utility model relates to a kind of valve, especially a kind of flexibility concentric high temperature metal seal ball valve.
Background technique
Ball valve is the main valve class in the valve, mainly comprises valve seat, valve body, valve rod and spheroid.Conventional ball valve comprises soft sealing ball valve and hard seal ball valve, limited by its sealing material and structure, limits to its wider using scope.There is following shortcoming specifically:
1, serviceability temperature is difficult to cross over 450 ℃.Under the high-temperature situation, the seal leakage hidden danger between valve seat and the valve body.
2, wear-resisting property is poor, is not suitable for the pipeline of graininess with solid thing class medium.
3, under high temperature and the high pressure conditions, the seal leakage hidden danger of stem packing; The static seal of valve body joint is revealed hidden danger.
More than some, conventional ball valve is difficult to the problem that solves and often run on the pipeline of high temperature, high pressure and abrasiveness (band graininess with solid thing class medium).
Summary of the invention
The purpose of this utility model can be used the flexibility concentric high temperature metal seal ball valve of good seal performance for providing a kind of in high temperature, high pressure and abrasiveness medium.
The technological scheme that realizes the foregoing invention purpose is as follows:
Flexibility concentric high temperature metal seal ball valve, comprise valve body, support valve seat, spheroid and valve rod, valve body is divided into valve body and connecting body, be provided with the triangular pyramidal sealing gasket between valve body and the connecting body, be provided with composite filling between valve rod and the valve body, the valve rod upper end is provided with rack platform and links to each other with valve body, and described connecting body interior edge face forms valve seat.
Be provided with spring between described support valve seat and the valve body.
Be provided with thrust bearing between described stem lower portion and the valve body.
Described rack platform middle part has groove, is provided with the stem guiding cover in the groove, and the stem guiding cover is socketed on the valve rod upper end.
The utility model valve seat and connecting body are integrated, have stopped the leakage between valve seat and the valve body.Combined composite filling has been realized the reliable sealing of valve rod and valve body joint.Tapered valve seal pads the reliable sealing that has showed the valve body joint, and especially under the high span changing condition of High Temperature High Pressure, the high sealing effect is good more more for pressure, temperature within the specific limits.The combination of valve rod and thrust bearing and stem guiding cover has promptly solved valve rod accidental under high pressure conditions, and the concentric rotation that has realized valve rod again is unlikely to depart from and damages composite filling.The design of spring has realized compensation sealing and has absorbed the heat expansion phenomenon.
Description of drawings
Fig. 1 is the utility model internal structure schematic representation
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1,
Flexibility concentric high temperature metal seal ball valve, comprise valve body, support valve seat, valve seat, spheroid and valve rod, valve body is divided between valve body 1 and the connecting body 2 and is provided with triangular pyramidal sealing gasket 8, be provided with composite filling 10 between valve rod 7 and the valve body 1, described connecting body 2 interior edge faces form valve seat 5, support between valve seat 4 and the valve body 1 and be provided with spring 3, spheroid 6 and support valve seat 4 and valve seat connecting part, be provided with thrust bearing 9 between stem lower portion and the valve body, described valve rod 7 upper ends are provided with rack platform 12 and link to each other with valve body 1, rack platform 12 middle parts have groove, are provided with stem guiding cover 11 in the groove, and stem guiding cover 11 is socketed on the valve rod upper end.
