Abstract
The utility model provides a double sealing high temperature high pressure elasticity ball valve seating structure, includes spheroid, disk seat, sealing washer I, sealing washer II, spring holder, spring, clamping ring, presses cover, valve body, disk seat butt spheroid end is equipped with a deep groove, the disk seat is equipped with two endocentric sealing washers I, sealing washer I is fixed through the spring holder, an installation spring on the spring holder, the spring top is on the clamping ring, the clamping ring with press and be equipped with two concentric sealing washers II between the cover, press cover and valve body butt. The beneficial effects of the utility model are that, the high temperature high pressure ball valve structure after the improvement has double seal, and simultaneously, the disk seat has certain elasticity in addition, can effectively reduce the risk that the medium leaked, guarantees the security that the valve used at the site work condition.
Description
Technical Field
The utility model relates to a double seal high temperature high pressure elasticity ball valve disk seat structure.
Background
The current high-temperature high-pressure ball valve generally only has a packing seal ring structure, and there is not the elastic construction design between disk seat and the spheroid, and under the high temperature operating mode, one packing seal structure is not only short-lived, and sealed effect is not good moreover. The valve seat and the ball body are designed to have no elastic structure, so that the valve seat and the ball body have no elasticity, the valve seat and the ball body cannot be in good contact, and leakage is easy to generate. When a packing seal ring has a problem, the medium can leak from the packing seal ring. Therefore, the high-temperature and high-pressure ball valve structure with the existing structure has certain defects, easily causes medium leakage, and cannot ensure the safety of the valve in use under the field working conditions.
SUMMERY OF THE UTILITY MODEL
In order to overcome the prior art problems, the utility model provides a double sealing high temperature high pressure elasticity ball valve disk seat structure.
The technical scheme of the utility model, a double sealing high temperature high pressure elasticity ball valve seating structure, include spheroid, disk seat, sealing washer I, sealing washer II, spring holder, spring, clamping ring, press cover, valve body, disk seat butt spheroid end is equipped with a deep groove, the disk seat is equipped with two endocentric sealing washers I, sealing washer I is fixed through the spring holder, an installation spring on the spring holder, the spring top is on the clamping ring, the clamping ring with press and be equipped with two endocentric sealing washers II between the cover, press cover and valve body butt.
The beneficial effects of the utility model are that, when the valve closing during operation, the clamping ring plays first way sealedly with sealing washer I of disk seat lower extreme with pressing two between the cover concentric sealing washer II, and sealing washer I of disk seat upper end plays the second and says sealedly when first way sealed inefficacy, and double seal structure guarantees the reliability of valve seal. The valve seat with the deep groove structure is designed to ensure that the valve seat has certain elasticity, and the valve seat ensures elastic contact between the valve seat and the ball body under the action of the spring and medium force, so that sealing is facilitated. The improved high-temperature and high-pressure ball valve structure can effectively reduce the risk of medium leakage and ensure the safety of the valve in use under the field working conditions.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a sphere; 2. a valve seat; 3. a sealing ring I; 4. a spring seat; 5. a spring; 6. pressing a ring; 7. pressing the sleeve; 8. a sealing ring II; 9. a valve body.
Detailed Description
As shown in fig. 1, the double-sealing high-temperature high-pressure elastic ball valve seat structure comprises a ball body, a valve seat, a sealing ring I, a sealing ring II, a spring seat, a spring, a pressing ring, a pressing sleeve and a valve body, wherein a deep groove is formed in the end, abutted to the ball body, of the valve seat, the valve seat is provided with two concentric sealing rings I, the sealing rings I are fixed through the spring seat, the spring is mounted on the spring seat and abuts against the pressing ring, two concentric sealing rings II are arranged between the pressing ring and the pressing sleeve, and the pressing sleeve is abutted to the valve body.
The working principle is as follows: when the valve is closed to work, the compression ring and the pressure sleeve have a first seal with the two concentric seal rings II and the seal ring I at the lower end of the valve seat, when the first seal fails, the seal ring I at the upper end of the valve seat has a second seal, and the dual-seal structure ensures the reliability of the valve seal. The valve seat with the deep groove structure is designed to ensure that the valve seat has certain elasticity, and the valve seat ensures elastic contact between the valve seat and the ball body under the action of the spring and medium force, so that sealing is facilitated. The improved high-temperature and high-pressure ball valve structure can effectively reduce the risk of medium leakage and ensure the safety of the valve in use under the field working conditions.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
