Abstract
The utility model provides a sealing structure of a high platform ball valve. The sealing structure comprises a valve body, a valve rod, a stuffing and a gland, wherein the valve rod is arranged in the valve body; a stuffing box is arranged between the valve body and the valve rod; the stuffing and the gland are arranged in the stuffing box; the gland is arranged at an upper end of the stuffing; an O-shaped sealing ring is arranged between a lower end of the stuffing and the valve body; and a thrust washer is arranged between a lower end of the valve rod and the valve body. By the sealing structure of the high platform ball valve, a combined sealing mode of the O-shaped sealing ring, the stuffing and the thrust washer is adopted, when pressure is low, the valve rod is directly sealed by the thrust washer, and when the pressure is high, the valve rod is sealed under the combined action of the O-shaped sealing ring and the stuffing. Because of the adjustment of the O-shaped sealing ring, high sealing performance can be ensured in spite of constant pressure and pressure rise or pressure drop caused by unstable factors, so that the service life of the high platform ball valve is greatly prolonged.
Description
Technical field
The utility model belongs to the ball valve field, is specifically related to a kind of sealing configuration of high platform ball valve.
Background technique
The closure member of high platform ball valve is a spheroid, and spheroid is done rotation around the valve body center line and reached opening and closing, and high platform ball valve mainly is used for making cut-out, distributes and change the flow direction of medium in pipeline.Existing high platform ball valve valve rod place only adopts packing seal, and this sealing configuration can reach good sealing effect under the situation of constant voltage; But when the pressure in the pipeline raise or reduce, the sealability here will reduce, thereby makes the lost of life of high platform ball valve.
The model utility content
The utility model provides the sealing configuration of the better high platform ball valve of a kind of sealability to the deficiency of above-mentioned existing technology.
The utility model is realized through following technological scheme:
A kind of sealing configuration of high platform ball valve comprises valve body, valve rod, filler and gland, and valve rod is arranged in the valve body, is provided with stuffing box between valve body and the valve rod, and filler and gland are arranged in the stuffing box, and gland is located at the upper end of filler;
It is characterized in that, be provided with an O RunddichtringO between the lower end of said filler and the valve body, be provided with a thrust washer between the lower end of said valve rod and the valve body.
The further setting of the utility model is that said gland is pressed on the valve body.
The sealing configuration of the described high platform ball valve of the utility model; On the basis of original valve rod leak-proof structure, improve; It has adopted the combination seal mode of O RunddichtringO, filler and thrust washer; When low pressure, directly by thrust washer the valve rod place is sealed, the acting in conjunction by O RunddichtringO and filler when high pressure seals the valve rod place; Because the adjusting of O RunddichtringO is arranged,, still, all can guarantee excellent sealing performance, thereby prolong the working life of high platform ball valve greatly in the utility model because the pressure that destabilizing factor causes raises or reduces no matter in constant voltage.
Description of drawings
Fig. 1 is the structural drawing of the sealing configuration of the said high platform ball valve of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in Figure 1, a kind of sealing configuration of high platform ball valve comprises valve body 1, valve rod 2, filler 3 and gland 4; Valve rod 2 is arranged in the valve body 1; Be provided with stuffing box between valve body 1 and the valve rod 2, filler 3 is arranged in the stuffing box with gland 4, and gland 4 is located at the upper end of filler 3; Be provided with an O RunddichtringO 5 between the lower end of said filler 3 and the valve body 1, be provided with a thrust washer 6 between the lower end of said valve rod 2 and the valve body 1.6 pairs of valve rod 2 places sealings of direct thrust washer when low pressure, the acting in conjunction of O RunddichtringO 5 and filler 3 seals the valve rod place when high pressure.In order to prevent to become flexible, said gland 4 is pressed on the valve body 1.
The above is the preferred embodiment of the utility model, and all equivalent variations of being done according to the utility model claim all should belong to the protection domain of the utility model.
Claims (2)
1. the sealing configuration of a high platform ball valve comprises valve body, valve rod, filler and gland, and valve rod is arranged in the valve body, is provided with stuffing box between valve body and the valve rod, and filler and gland are arranged in the stuffing box, and gland is located at the upper end of filler; It is characterized in that, be provided with an O RunddichtringO between the lower end of said filler and the valve body, be provided with a thrust washer between the lower end of said valve rod and the valve body.
