Abstract
The invention discloses a sealing device for high pressure and variable pressure conditions, which comprises a shaft sleeve, O-shaped rings, a non-compensation ring, a compensation ring, a spring, a sealed cavity, a packing gland, an anti-rotating pin component, a support ring and a threaded pin. The non-compensation ring and the threaded pin are mounted on the shaft sleeve, the compensation ring, the spring, the packing gland and the support ring are mounted on the sealed cavity, and the anti-rotating pin component is mounted on the compensation ring. A main seal, namely a mechanical seal, of the sealing device for high pressure and variable pressure conditions can meet the rudiments of operational stability and reliability in high pressure and pressure fluctuating operational environments. The emergency protection sealing device can be demounted and mounted on the spot conveniently, and can be used at the fastest speed. The sealing device plays a substantial role in solving the problem that requirements of in-situ sealing and emergency protection under high pressure and pressure fluctuating conditions cannot be met, improving production efficiency and minimizing loss of customers under accidents at the fastest speed.
Description
Technical field
The present invention relates to a kind of seal arrangement that is used for high pressure, transformation power operating mode.
Background technique
Majority peculiar to vessel with commercial Application in, seal arrangement not only will bear high pressure, but also will bear the working condition of pressure surge; And a lot of industries also requirement will have the emergency protecting equipment of easy disassembly; The existing seal arrangement that is applied to this mainly is made up of mechanical seal and packing seal, and mechanical seal is primary seal, and packing seal is the emergency protection sealing; Thereby reach the effect of sealing and emergency protection; But existing seal arrangement especially primary seal holds in the complex working condition environment that can't stand variation in pressure, high pressure, and emergent seal arrangement dismounting is inconvenient, and the emergency protection seal arrangement is come into operation; Can not satisfy under high pressure, pressure surge working condition the demand of on-the-spot sealing and emergency protection to a great extent, problem that existing seal arrangement has that Here it is.
Summary of the invention
The purpose of this invention is to provide a kind of seal arrangement that is used for high pressure, transformation power operating mode.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of seal arrangement that is used for high pressure, transformation power operating mode; Comprise axle sleeve (1), O shape circle (2; 12; 13), uncompensated ring (3), compensated loop (4), spring (5), seal chamber (7), Gland (8), stop pin assembly (10), support ring (11), threaded (14); Said O shape circle (2) is installed on the uncompensated ring (3), and uncompensated ring (3) and threaded (14) are installed on the axle sleeve (1), and compensated loop (4), spring (5), Gland (8) and support ring (11) are installed on the seal chamber (7); Stop pin assembly (10) and O shape circle (12) are installed on the compensated loop (4), and O shape circle (13) is installed in the axle sleeve (1).
Filler (6) is installed on the said seal chamber (7).
Said Gland (8) is the split structure, and two lobes of Gland (8) are installed through socket head screw (15) symmetry.
Said socket head screw (15) is fixing through hexagon head bolt (9).
A kind of seal arrangement that is used for high pressure, transformation power operating mode of the present invention, seal arrangement primary seal are that mechanical seal can be satisfied stable, reliable work demand in the work condition environment of high pressure, pressure surge; The structure of emergency protection seal arrangement can make things convenient for on-the-spot dismounting, can make the emergency protection sealing come into operation with the fastest speed.This shows; The present invention is to separating the problem of the demand that must not satisfy under high pressure, pressure surge working condition on-the-spot sealing and emergency protection; Improved manufacturing efficiency, farthest reduced the loss of client under unexpected situation, played substantial effect with the fastest speed.
Description of drawings
Fig. 1 is a kind of seal arrangement sectional view that is used for high pressure, transformation power operating mode of the present invention.
Fig. 2 is the plan view of the Gland of the present invention's seal arrangement of being used for high pressure, transformation power operating mode.
Among the figure: 1. axle sleeve; 2.O shape circle; 3. uncompensated ring; 4. compensated loop; 5. spring; 6. filler; 7. seal chamber; 8. Gland; 9. hexagon head bolt; 10. stop pin assembly; 11. support ring; 12.O shape circle; 13.O shape circle; 14. threaded; 15. socket head screw.
Embodiment
As depicted in figs. 1 and 2, be used for the seal arrangement of high pressure, transformation power operating mode, comprise axle sleeve 1, O shape circle 2, uncompensated ring 3, compensated loop 4, spring 5, seal chamber 7, Gland 8, stop pin assembly 10, support ring 11, O shape circle 12, O shape circle 13 and threaded 14; O shape circle 13 is encased in the axle sleeve 1, threaded is installed on the axle sleeve 1, O shape circle 2 is installed on the uncompensated ring 3; Uncompensated ring 3 is installed on the axle sleeve 1, spring 5 and support ring 11 are installed on the seal chamber 7, O shape circle 12 is installed on the compensated loop 4; Pin assemblies 10 is installed on the compensated loop 4, and pin assemblies 10 is that pin and throw-out collar interference fit form here, like this can be so that pin assemblies 10 has well following property with compensated loop 4 with O shape circle 12 under variation in pressure, high pressure working condition; Compensated loop 4 is installed on the seal chamber 7, axle sleeve 1 is passed seal chamber 7, make friction pair be close to; Filler 6 is installed to seal chamber 7; Install the Gland 8 usefulness socket head screws 15 of distinguish, notice that here socket head screw 15 wants symmetry to install, guarantee that two lobes fit fully; Gland 8 is installed to seal chamber 7; The structure that compensated loop and uncompensated ring are installed O shape circle place makes axial compression is arranged O shape circle existing radial compression in the environment of high pressure and pressure surge again, and cavity is provided with support ring and prevents that O shape from enclosing and released by hydrodynamic pressure; Favorable sealing property, medium can not leak from the auxiliary seal point; The threaded transmission is adopted in transmission between axle sleeve and the uncompensated ring, and wherein threaded cooperates with sleeve thread, threaded and uncompensated ring Spielpassung, and this transmission is reliable and stable at high pressure and pressure surge situation underdrive; The rotation prevention structure of compensated loop adopts the composite structure of straight pin and throw-out collar; Straight pin and throw-out collar adopt interference fit; This assembly parts and compensated loop adopt Spielpassung, and this structure has good following property with compensated loop in the environment of high pressure and pressure surge, and compensated loop can not knocked bad by this structure.So in the equipment operation process; In the environment of high pressure, pressure surge, the primary seal of this seal arrangement be mechanical seal structure have well float, following property, can regulate according to the duty parameter self adaption; All the time guarantee that seal face tightly fits, guarantee sealability; The emergency protection seal arrangement of this seal arrangement adopts splitted structure, and this structure is convenient to dismounting very much, and the distinguish place adopts relative bolton; Stressed even; The distinguish place fits fine, reaches the working position fast so this mechanism can guarantee the emergency protection seal arrangement, and then comes into operation.
