Abstract
A kind of general plug structure of elastic packing, including sphere, limited block, general plug, fixator, the general plug is made of external lip, contained spring accumulation of energy circle, the general plug is embedded in the mounting groove of fixator, the limited block is fixedly connected with fixator, the limited block is abutted with general plug, and the external lip of the general plug is abutted with spherome surface.The beneficial effects of the invention are as follows, under the operating condition of ultralow temperature, although general plug is inconsistent with the shrinking percentage of fixator, gap between the two can be made up by the spring energy-storage circle inside general plug, to eliminate the risk of leakage of general plug and fixator, it is ensured that the leakproofness of valve.
Description
Technical field
The present invention relates to a kind of general plug structures of elastic packing.
Background technique
LNG has vast potential for future development as a kind of new energy.In recent years, with middle petroleum, middle petrochemical industry and in
Intervention of the Hai Youdeng energy company to LNG industry, Chinese LNG receiving station construction is more and more, also uses in LNG receiving station
A large amount of Subzero valve realizes the transport of LNG.
Ultra-low temperature ball valve accounts for 80% or more of low temperature valve total amount in LNG receiving station at present, but existing cryogenic ball valve mostly uses
The sealing being embedded between the high molecular polymers such as the PCTFE in Metallic anchors realization sphere and valve seat.The structure is specifically wrapped
Include the high molecular polymers such as sphere, PCTFE, spring, fixator.In the work of worst cold case lower valve, since PCTFE is contour
The linear expansion coefficient of Molecularly Imprinted Polymer is greater than fixator, and the shrinking percentage of the high molecular polymers such as PCTFE at low temperature is greater than solid
The shrinking percentage for determining device causes the internal-and external diameter of the high molecular polymers such as PCTFE that cannot be in contact with fixator, is in quick condition.?
When valve opening or closing, the power that sphere rotation generates will drive the high molecular polymers such as PCTFE and move in fixator,
To form leakage path, so as to cause the interior leakage of valve.
Summary of the invention
To overcome above-mentioned prior art problem, the present invention provides a kind of general plug structures of elastic packing.
The technical scheme is that a kind of general plug structure of elastic packing, including sphere, limited block, general plug, fixator,
The general plug is made of external lip, contained spring accumulation of energy circle, and the general plug is embedded in the mounting groove of fixator, the limit
Block is fixedly connected with fixator, and the limited block is abutted with general plug, and the external lip of the general plug is abutted with spherome surface.
The invention has the advantages that under the operating condition of ultralow temperature, although general plug is inconsistent with the shrinking percentage of fixator,
It is that gap between the two can be made up by the spring energy-storage circle inside general plug, is let out to eliminate general plug with fixator
It leaks out danger, it is ensured that the leakproofness of valve.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1. spheres；2. limited block；3. general plug；31. general portion's lip beyond the Great Wall；32. general plug contained spring accumulation of energy
Circle；4. fixator.
Specific embodiment
As shown in Figure 1, a kind of general plug structure of elastic packing, including sphere, limited block, general plug, fixator, the general plug by
External lip, contained spring accumulation of energy circle composition, the general plug are embedded in the mounting groove of fixator, the limited block and fixator
It is fixedly connected, the limited block is abutted with general plug, and the external lip of the general plug is abutted with spherome surface.
