Abstract
Double-layer sleeve structure is protected the invention discloses a kind of valve, there is externally threaded connector drum including outer ring, it is arranged at the sealing station of connector drum end, one end carries internal thread and the outer casing being threadedly coupled with connector drum, match and engage and middle part offers the envelope of through hole with sealing station, it is fixed on envelope seat and stretches out in the outer casing other end and the interior installing pipe coaxial with outer casing, it is arranged at the outer casing other end and the fixed seat being socketed with interior installing pipe, the fixed lid for being socketed and being fixedly connected with fixed seat with interior installing pipe, it is arranged at the external thread part on the outer wall of interior fixed lid one end of installing pipe correspondence, and screw thread is socketed in interior installing pipe and closes the exterior seal ring in gap between interior installing pipe and fixed lid.The present invention using outer casing carries out that insulation material can be filled between Double-protection, and ectonexine or vacuumizes realization to the temperature isolation in valve core valve stem, play effective protective effect by the use of interior installing pipe as the passage for installing valve core valve stem.
Description
Technical field
It is to be related to a kind of valve protection double-layer sleeve structure specifically the invention belongs to valve mechanism technical field.
Background technology
Valve is the important component of control fluid transmission lines switch in pipeline engineering.In the pipe of some transmission cryogens
Lu Zhong, pipeline can usually cause the water recovery and icing of pipeline external surface because of fluid heat-absorbing action, and on the one hand pipeline freezes
Pipeline load-bearing increase can be made, on the other hand the stability at influence pipe joint position, be attached to volume after the water freezing of pipeline outer wall
Expansion, produces squeezing action to pipeline, exists the potential safety hazard of pipeline pressure break.How to carrying out effectively protecting into outside valve
The problem of considering for our emphasis.
The content of the invention
To overcome not enough problem of the prior art, the present invention provides a kind of good valve of ingenious in design, protection effect and prevented
Protect double-layer sleeve structure.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of valve protects double-layer sleeve structure, including outer ring to have externally threaded connector drum, is arranged at connector drum
The sealing station of end, one end with internal thread and the outer casing that be threadedly coupled with connector drum, matched with sealing station engage and in
Portion offers the envelope seat of the through hole coaxial with outer casing, is fixed on envelope seat and stretches out in the outer casing other end and same with outer casing
The interior installing pipe of axle, is arranged at the outer casing other end and the fixed seat being socketed with interior installing pipe, is socketed with interior installing pipe and with consolidating
The fixed lid that reservation is fixedly connected, is arranged at the external thread part on the outer wall of interior fixed lid one end of installing pipe correspondence, and screw thread
It is socketed in interior installing pipe and closes the exterior seal ring in gap between interior installing pipe and fixed lid.
Further, it is provided with inner seal ring between the fixed seat and fixed lid.
Also, the sealing station is provided with sealing ring.
Compared with prior art, the invention has the advantages that：
The present invention carries out Double-protection by the use of interior installing pipe as the passage for installing valve core valve stem using outer casing, and
Insulation material can be filled between ectonexine or realization is vacuumized to the temperature isolation in valve core valve stem, effectively protection is played and makees
With ensureing that the protective zone between bilayer is closed by setting air locking at inner/outer tube two ends, it is to avoid by external temperature
With the influence of steam, protection effect is improved, and the present invention is ingenious in design, it is simple in construction, it is with low cost, it is easy to use, have
Prospect is widely applied, is adapted to popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
Embodiment
As shown in figure 1, the valve protects double-layer sleeve structure, including outer ring to have externally threaded connector drum 1, it is arranged at
The sealing station 2 of connector drum end, one end carries internal thread and the outer casing 3 being threadedly coupled with connector drum, with sealing station
The envelope seat 4 of the through hole coaxial with outer casing is offered with engagement and middle part, is fixed on envelope seat and stretches out in the outer casing other end
And the interior installing pipe 5 coaxial with outer casing, the outer casing other end and the fixed seat 6 being socketed with interior installing pipe are arranged at, with interior peace
The fixation lid 7 that tubulature is socketed and is fixedly connected with fixed seat, is arranged at outer on the outer wall of interior fixed lid one end of installing pipe correspondence
Threaded portion, and screw thread are socketed in interior installing pipe and close the exterior seal ring 8 in gap between interior installing pipe and fixed lid.Enter one
Step ground, inner seal ring 9 is provided between the fixed seat and fixed lid.Also, the sealing station is provided with sealing ring 10.
The general valve rod valve element and valve body for coordinating valve of the invention is used in conjunction with, and valve body is connected with connector drum, valve rod valve
Core is installed from interior installing pipe, outside to control valve core rotation or lifting by devices such as rolled rounds；The sealing ring of lower end can ensure to connect
The fluid leakage passed through in cylinder is connect, interior exterior seal ring has fully ensured that the closing in the space between outer casing and interior installing pipe
Property；It is overall to use cylinder form, can be more preferable to the isolation effect between lower end valve body and upper end outside.
Above-described embodiment is only the preferred embodiments of the present invention, not limiting the scope of the invention, as long as using
The design principle of the present invention, and the change for carrying out non-creativeness work on this basis and making, all should belong to the present invention's
Within protection domain.
