Abstract
The utility model discloses a kind of vacuum furnace gasket structures, it include annular sealing strip ontology, the front side of annular sealing strip ontology has the annular shirt rim of integrally connected, triangle, the inside and outside side of annular shirt rim are to the inclined inclined-plane in the outside of annular sealing strip ontology in obtuse angle in the section of annular shirt rim.The utility model structure is simple, lower to the flatness processing request in oven door sealing face to initial compression force request very little, it is i.e. stronger to the fault tolerance of the flatness in oven door sealing face, reduce the processing cost of fire door, and can quick release pressure, avoid the risk to build the pressure after vacuum breaker.
Description
Technical field
The utility model relates to vacuum furnace field, specifically a kind of vacuum furnace gasket structure.
Background technique
Equipment of the vacuum furnace as vacuum electric heating is generally realized sealing using common O-ring sealing strip, is needed
Initial pressing force is big and higher to the flatness processing request in oven door sealing face；In addition, being unable to quick release pressure after vacuum breaker
Power, the risk for thering is positive pressure to build the pressure.
Utility model content
The purpose of the utility model is to provide a kind of vacuum furnace gasket structures, compress force request very to initial
It is small, it is lower to the flatness processing request in oven door sealing face, and avoid the risk to build the pressure after vacuum breaker.
The technical solution of the utility model is as follows:
A kind of vacuum furnace gasket structure includes annular sealing strip ontology, it is characterised in that: the annular is close
The front side of strip of paper used for sealing ontology has the annular shirt rim of integrally connected, the section of annular shirt rim triangle in obtuse angle, annular shirt rim
Inside and outside side be the inclined inclined-plane in outside to the annular sealing strip ontology.
The vacuum furnace gasket structure, it is characterised in that: the annular sealing strip ontology is mounted on very
In the furnace sealing slot of empty heating furnace.
The vacuum furnace gasket structure, it is characterised in that: the medial surface of the annular shirt rim and the ring
Angle between the center line of shape weatherstrip body is greater than between its lateral surface and the center line of the annular sealing strip ontology
Angle.
The vacuum furnace gasket structure, it is characterised in that: the medial surface of the annular shirt rim is and vacuum
The sealing surface that Compaction of Heating Furnace Door fits.
The utility model has the beneficial effects that
The utility model structure is simple, force request very little is compressed to initial, to the flatness processing request in oven door sealing face
It is lower, i.e., it is stronger to the fault tolerance of the flatness in oven door sealing face, the processing cost of fire door is reduced, and being capable of quick release
Pressure avoids the risk to build the pressure after vacuum breaker.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the A-A of Fig. 1 to structural front view.
Fig. 3 is the structure enlargement diagram of part B in Fig. 2.
Specific embodiment
Referring to attached drawing, a kind of vacuum furnace gasket structure includes annular sealing strip ontology 1, annular sealing strip
The front side of ontology 1 has an annular shirt rim 2 of integrally connected, the section of annular shirt rim 2 triangle in obtuse angle, annular shirt rim 2 it is interior,
Lateral surface 3,4 is to the inclined inclined-plane in the outside of annular sealing strip ontology.
In the utility model, annular sealing strip ontology 1 is mounted in the furnace sealing slot of vacuum furnace.
Angle between the medial surface 3 of annular shirt rim 2 and the center line of annular sealing strip ontology 1 be greater than its lateral surface 4 with
Angle between the center line of annular sealing strip ontology 1.
The medial surface 3 of annular shirt rim 2 is the sealing surface to fit with heating in vacuum furnace door.
The utility model is further described below in conjunction with attached drawing:
Annular sealing strip ontology 1 is mounted in the furnace sealing slot of vacuum furnace.It is vacuum state in furnace, i.e., is in furnace
When negative pressure, fire door is closed, the compression of annular shirt rim 2 expands outwardly, and medial surface 3 and the fire door of annular shirt rim 2 fit, to initial pressure
Clamp force requires very little, lower to the flatness processing request in oven door sealing face, i.e., to the tolerance energy of the flatness in oven door sealing face
Power is stronger；In furnace after vacuum breaker, i.e., when being positive pressure in furnace, fire door is opened, annular shirt rim 2 is pressurized to contract, annular shirt rim 2
Medial surface 3 is easily separated with fire door, and quick release pressure avoids the risk to build the pressure after vacuum breaker.
Above embodiment is only that the preferred embodiment of the utility model is described, not to the utility model
Protection scope be defined, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art to this
The modification and improvement that the technical solution of utility model is made should all be fallen into the protection scope of the utility model.
