Abstract
The invention discloses a novel membrane separator sealing device. The device comprises a clamping sleeve nut, a clamping sleeve made of a non-metal material, and a welding clamping sleeve concave base. The welding clamping sleeve concave base is arranged on the lower portion of the device and can be connected with the flange face of other container cavity to form a medium-and-low-pressure space; a metal pipe sequentially penetrates through the clamping sleeve nut, the non-metal clamping sleeve and the welding clamping sleeve concave base from outside and is reliably connected with a membrane separator in the container cavity in a sealed mode, and internal space of the metal pipe and internal space of the membrane separator form a high-pressure space together. The portion between the medium-and-low-pressure space and atmosphere is sealed, the conical face of the non-metal clamping sleeve makes full contact with the conical face of the welding clamping sleeve concave base by screwing the clamping sleeve nut, and sealing is formed. The device is low in machining and manufacturing requirement, can be conveniently and repeatedly detached, and is stable and reliable in sealing performance.
Description
Technical field
The invention mainly relates to technical field, particularly relate to a kind of new membrane separator sealing device.
Background technology
At present, the membrane separator on market cannot bear elevated pressures, and can the membrane separator of pressure-bearing be required for the most customized, and cost is the highest, deficiency in economic performance.This Application comparison allowing for membrane separator is limited, and it is more complicated to utilize membrane separator to carry out the technological process of gas separation, and system manufacturing cost is high, debugging difficulty.
Someone developed the sealing structure of gasket type later, membrane separator is arranged on the inside cavity of sealing, thus improve the bearing capacity of membrane separator, but the length dimension required precision that the sealing structure of this gasket type is to membrane separator, dimensional accuracy and the position accuracy demand of external cavity are the highest, make simultaneously because membrane separator housing is nonmetallic materials, intensity is the highest, the pretightning force being imparted on sealing gasket can not be the biggest, this sealing property allowing for gasket type sealing structure is unreliable, and once there is mutually leakage in high-pressure space and mesolow space, cannot accurately detect.
Here it is the bottleneck of membrane separator application at present.
Summary of the invention
The object of the invention is just to provide a kind of cheap membrane separator sealing device reliably, improves the bearing capacity of membrane separator, expands the range of application of membrane separator.
The present invention is achieved by the following technical solutions:
Sealing device is characterised by: include welding cutting ferrule dimple, cutting ferrule nut, nonmetal cutting ferrule.The conical surface of the conical surface of nonmetal cutting ferrule, inwall and welding cutting ferrule dimple is sealing surface；Cutting ferrule nut is threaded with welding cutting ferrule dimple, during tightening, cutting ferrule nut extrudes nonmetal cutting ferrule makes it be deformed so that the conical surface of nonmetal cutting ferrule is formed with the conical surface welding cutting ferrule dimple and seals, and nonmetal cutting ferrule inwall is formed with metal tube outer wall and seals.Metal tube sequentially passes through cutting ferrule nut, nonmetal cutting ferrule, welding cutting ferrule dimple, is connected with the membrane separator thread seal in cavity.
The advantage of this sealing system is as follows:
1, high-pressure space, between mesolow space and air sealing assembling can sequentially carry out, and be easy to leak detection operation；
2, inside cavity high-pressure space seals and uses single thread seal, seals reliable and stable；
3, the sealing structure between mesolow space and air, the requirement to processing and manufacturing is relatively low, it is simple to repeatedly dismantle, and sealing property is reliable and stable；
4, the deformation of nonmetal cutting ferrule is irreversible, and this part belongs to disposable, can effectively prevent the violation of putamina from dismantling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, sealing device, including and have female thread in the middle of cutting ferrule nut 1, cutting ferrule nut 1, be connected with the external screw thread of welding cutting ferrule dimple 2, metal tube 4 passes along the axis of cutting ferrule nut 1；
Welding cutting ferrule dimple 2, the conical surface of its middle indent forms sealing surface with the conical surface outside nonmetal cutting ferrule 3, and metal tube 4 passes along its axis；
Nonmetal cutting ferrule 3 is under the squeezing action of cutting ferrule nut 1, and its outer wall conical surface and inner surface are formed with the part matched respectively and seal.
Metal tube first connects with membrane separator, after confirming No leakage, then carries out above assembly work.
Claims (1)
1. membrane separator sealing device, it is characterised in that: include cutting ferrule nut, cutting ferrule that nonmetallic materials are made, welding cutting ferrule dimple；Device bottom is welding cutting ferrule dimple, can be connected with other container cavity flange faces, forms mesolow space；Metal tube sequentially passes through cutting ferrule nut, nonmetal cutting ferrule, welding cutting ferrule dimple from outside, reliably seals with the membrane separator within container cavity and is connected, and metal tube inner space forms high-pressure space together with membrane separator inner space；Sealing between mesolow space and air, is by tightening cutting ferrule nut, makes the conical surface of nonmetal cutting ferrule be fully contacted with the conical surface welding cutting ferrule dimple, the sealing of formation.
