Abstract
The utility model relates to a sealing device of flat gate valve used in petroleum industry, which is characterized in that a compound seal device is provided at the upper and lower stuffing box point. The compound seal device is a lip shape and O shape rubber ring or Y shape and O shape rubber ring. So that the improved stuffing box adopts the lip shape and O shape rubber ring or Y shape and O shape rubber ring to seal, which has good sealing effect, lower friction force to the valve stem, small torque moment to the start and stop of the valve, and is labor-saving.
Description
Technical field
The utility model relates to a kind of seal arrangement of plate valve of petroleum industry use.
Background technique
Plate valve of the prior art stuffing box up and down seals with U-shaped folder fabric rubber seal, and when strictness of sealed letter size requirement and expenses of labour, sealing effect is poor, and is bigger to the frictional force of valve rod, the valve opening and closing effort.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of seal arrangement of plate valve is provided, and not only effectively solves the problems of the prior art.
For achieving the above object, the technological scheme that the present invention takes is: the seal arrangement of described a kind of plate valve, its characteristics are: the place of stuffing box up and down of described plate valve is provided with composite seal device.Described composite seal device is lip type and O type combination rubber ring or Y type and O type combination rubber ring.
The beneficial effects of the utility model are: the seal arrangement of described a kind of plate valve, and it improves the back stuffing box and uses lip type and O type rubber ring or Y type and the seal with elastometic washer of O type instead, good sealing effect, little to the frictional force of valve rod, the valve opening and closing moment of torsion is little, and is laborsaving.
Description of drawings
Fig. 1 is a structural principle schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: as shown in Figure 1, the seal arrangement of described a kind of plate valve, its characteristics are: 21,22 places of stuffing box up and down of described plate valve 1 are provided with composite seal device 31,32 respectively.Described composite seal device 31 is lip type and O type combination rubber ring, and composite seal device 32 is Y type and O type combination rubber ring.
Embodiment 2: identical with embodiment 1, different is that described composite seal device 31 is Y type and O type combination rubber ring, and composite seal device 32 is lip type and O type combination rubber ring.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. the seal arrangement of a plate valve, it is characterized in that: the place of stuffing box up and down of described plate valve is provided with composite seal device.
2. the seal arrangement of a kind of plate valve as claimed in claim 1 is characterized in that: described composite seal device is lip type and O type combination rubber ring or Y type and O type combination rubber ring.
