Abstract
The invention discloses a sealing structure for a metal and glass. The sealing structure comprises a metal tube with a wedge-shaped retainer ring near a mouth of the tube; a glass window piece is placed on one side, close to the mouth of the tube, of the wedge-shaped retainer ring; the mouth of the metal tube is provided with an internal-thread structure; a threaded clamping ring squeezes the glass window piece through a thread structure so that the glass window piece is sealed with the wedge-shaped retainer ring of the metal tube; a relatively thin part of a front end of the wedge-shaped retainer ring on an inner wall of the metal tube may deform at a temperature above 60 DEG C to further increase a contact area and a squeezing force with the glass window piece, and therefore, an excellent sealing property is shown.
Description
Technical field
The present invention relates to the hermetically sealed connector of a kind of metal and glass.
Background technique
Glass and the traditional sealing configuration of metal mostly adopt and add seal washer and gluing method, these class methods sealing effect is at normal temperatures and pressures better, but at high temperature under high pressure, the packing ring uneven sealing that causes of being heated declines, and bonding method bonding force is not high, and viscose glue is chemical materials, at high temperature can discharge toxic gas, human body is damaged, befouling environment.
Summary of the invention
The object of the present invention is to provide a kind of hermetically sealed connector that just effectively can realize metal and glass capsulation at certain temperature range inside use packing ring.
A kind of metal of technical solution of the present invention and glass sealing structure, comprise the metal tube with wedge shape back-up ring near a mouth of pipe, a glass window sheet is placed with near mouth of pipe side at wedge shape back-up ring, the mouth of pipe of metal tube has female thread structure, a threaded ring makes the wedge shape retaining ring sealing of glass window sheet and metal tube by worm structure extruding glass window sheet, thinner position, inner wall of metal tube wedge shape back-up ring front end can produce deformation more than 60 DEG C.
A kind of metal of the present invention and glass sealing structure, the contact position of glass window sheet and metal tube is near inner wall of metal tube wedge shape back-up ring inward flange thinner position, and the using scope of sealing structure is within 200 DEG C.
A kind of metal of the present invention and glass sealing structure, inner wall of metal tube wedge shape back-up ring internal diameter and glass window sheet chamfer surface bore ratio range are 94%-90%, there is an angle in inner wall of metal tube wedge shape back-up ring and glass window sheet surface of contact, span is 1 °-10 °, and angular range is determined by the hardness of diaphragm.
The inner wall of metal tube wedge back-up ring front end thinner that technical solution of the present invention adopts is divided produce deformation more than 60 DEG C, increases further and the area of contact of glass window sheet and extruding force, thus shows good sealing characteristics.
The technology of the present invention beneficial effect:
Technical solution of the present invention does not use seal washer without the need to considering the problem of high temperature lower gasket temperature distortion, simultaneously sealing connector does not make the method that sticks with glue, toxic gas can not be discharged, environmental sound, in addition, can deformation be there is in this thinner position, connector metal pipe inner wall of metal tube wedge shape back-up ring front end metal, increase the area of contact of metal and glass, and the extruding force of metal and glass, sealing effect is more obvious, in addition sealing connector simplicity of design, is easy to processing and realizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Understand technical solution of the present invention for ease of those skilled in the art, now in conjunction with Figure of description, technical solution of the present invention is described further.
Main structure of the present invention comprises: with the metal tube 1 of wedge shape back-up ring, glass window sheet 2, threaded ring 3, and glass window sheet and wedge back-up ring outer side wall form angle 4.
In the embodiment of the present invention, wedge shape back-up ring is processed at the inwall of metal tube 1, glass window sheet 2 contacts with thinner position, metal tube 1 inwall wedge shape back-up ring front end, the processing of glass window sheet 2 and metal tube 1 inwall wedge shape back-up ring, the internal diameter of wedge shape back-up ring is 93% of glass window sheet chamfer surface bore, the angle 4 of glass window sheet and wedge shape back-up ring outer side wall is 2 °, and the surface Machining roughness of metal tube 1 inwall wedge shape back-up ring is better than 3.2 μm.At normal temperatures and pressures, glass window sheet 2 is extruded by threaded ring 3, make thinner position, wedge shape back-up ring front end close contact in itself and metal tube 1, at high temperature, wall wedge shape back-up ring inward flange thinner position is made to produce deformation, the area of contact of further increase and glass window sheet 2 and extruding force, thus show excellent sealing characteristic at high temperature, sealing structure allows using scope in 200 DEG C.
Technical solution of the present invention is exemplarily described invention by reference to the accompanying drawings above; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various unsubstantialities that method of the present invention is conceived and technological scheme is carried out to improve; or the design of invention and technological scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
Claims (3)
