Abstract
The utility model relates to a high-pressure parallel gate valve provided with composite sealing devices in chemical industry. The high-pressure parallel gate valve is characterized in that composite sealing devices are arranged at an upper stuffing box and a lower stuffing box of the high-pressure parallel gate valve, and can be lip-shaped and O-shaped combined rubber rings or Y-shaped and O-shaped combined rubber ring. The stuffing boxes are sealed by the lip-shaped and O-shaped combined sealing rings or the Y-shaped and O-shaped combined sealing rings after improvement, which has excellent sealing effect and small friction force to a valve rod, has small starting and closure torque of the valve, and is labor-saving.
Description
Technical field
The utility model relates to the high pressure Parallel gate valve Parallel slide valve that is provided with composite seal device that a kind of chemical industry is used.
Background technique
High pressure Parallel gate valve Parallel slide 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 high pressure Parallel gate valve Parallel slide valve that is provided with composite seal device 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: described a kind of high pressure Parallel gate valve Parallel slide valve that is provided with composite seal device, its characteristics are: the place of stuffing box up and down of described high pressure Parallel gate valve Parallel slide 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: described a kind of high pressure Parallel gate valve Parallel slide valve that is provided with composite seal device, it improves the back stuffing box and uses lip type and O type combination rubber ring or Y type and O type combination seal with elastometic washer instead, and good sealing effect is little to the frictional force of valve rod, the valve opening and closing moment of torsion is little, and is laborsaving.
