Abstract
The utility model discloses a ceramic hard seal check valve used at an inlet and an outlet of chemical equipment. A ceramic valve seat is in hot interference fit in a valve body, a ceramic spherical valve core and the ceramic valve seat are in arc surface hard seal matching, and the on/off function of the valve can be achieved by the flowing pressure and backflow pressure of medium and the own gravity of the ceramic valve core, so that the valve has good sealing effect. The ceramic spherical valve core and the ceramic valve seat are made of ultrahard wear-resistant industrial ceramics, so that the erosion abrasion of the medium is greatly reduced, and the service life of the check valve is greatly prolonged.
Description
Affiliated technical field:
The utility model relates to a kind of hard sealed valve device of pottery of transporting system, especially the chemical plant machinery is imported and exported or other only require unidirectional pipeline position by medium, this equipment is applicable to and contains solid fine particle and the bigger chemical mediator of stickiness, can effectively reduce abrasion loss in the medium process of circulation and ensure sealing effect.
Background technique:
At present, the structure of known safety check is by valve body, metal seat valve, metal spool assemblies, safety check only allows medium to flow to a direction, and stop mobile in the other direction, common safety check opens by medium thrust promotion metal spool and fed sheet of a media is to work automatically, when medium flows in the other direction, by medium back flow thrust metal spool is contacted with metal seat valve and reach sealing, thereby the cut-out medium back flow, because medium has transporting velocity faster, metal seat valve and metal spool are subject to wash away in the application, abrasion are big, working life is short, needs the frequent valve of changing, and this process circulates successively.
Summary of the invention:
In order to overcome shortcomings such as existing safety check abrasion are fast, the life-span is short, the utility model provides a kind of pottery to seal safety check firmly, and this pottery seals safety check firmly, and not only abrasion loss is little, the while long service life.
The technological scheme that its technical problem that solves the utility model adopts is: ceramic valve seat adopts the interference hot charging to cooperate with metal valve body in valve body, ceramic spherical spool and ceramic valve seat adopt cambered surface to seal firmly, has good sealing effect, medium thrust promotes ceramic valve core and reaches opening state, medium is carried from valve body to be passed through, because the material of ceramic valve core and ceramic valve seat is the industrial ceramics of superhard wear, can significantly reduce the erosion abrasion loss, reaches the purpose of long service life.
The beneficial effects of the utility model are: adopt the mode of ceramic arc face seal, sealing is tight, reduces wear life-saving.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a longitudinal section of the present utility model erection drawing
Fig. 2 is first embodiment's of the hard sealing of pottery safety check a longitudinal section tectonic maps
Fig. 3 is second embodiment's of pottery hard sealing safety check a longitudinal section tectonic maps
Embodiment:
1. valve bodies among the figure, 2. ceramic valve seat, 3. ceramic spherical spool.
In Fig. 1, valve body (1) is assembled into one with ceramic valve seat (2) interference heat, and ceramic valve seat (2) is sealed and matched firmly with ceramic spherical spool (3) cambered surface, by the flowing pressure of medium and the open and close effect that return pressure reaches valve.
In embodiment illustrated in fig. 2, valve body (1) is an interference fit with ceramic valve seat (2), adopts the hot charging mode to be fixed as one.
In the embodiment shown in fig. 3, ceramic spherical spool (3) adopts cambered surface to be sealed and matched firmly with ceramic valve seat (2).
Claims (1)
1. a pottery seals safety check firmly, be a kind of automatic valve, it is characterized in that: ceramic valve seat adopts the interference hot charging to cooperate with metal valve body, and its ceramic ball-type spool, ceramic valve seat material adopt industrial ceramics, sealing means adopts cambered surface to seal firmly, has good sealing effect.
