Abstract
The utility model relates to a single-side sealing ceramic gate valve. The problem that a ceramic gate plate of an existing ceramic gate valve is poor in impact resistance and cracks easily is mainly solved. The single-side sealing ceramic gate valve is characterized in that a flowing channel (6) is arranged in a valve body (2), a protruding tubular boss (7) is arranged at one end of the flowing channel (6), a ceramic valve seat (5) is circular-ring-shaped and nested outside the boss (7), the outer end face of the ceramic valve seat (5) is flush with or exceeds out of the boss (7), a metal connecting plate (8) is arranged between a valve rod (3) and a ceramic plate (4), one side of the metal connecting plate (8) is provided with a groove (9), and the ceramic plate (4) is fixed in the groove (9) and adheres to the end face of the ceramic valve seat (5). The single-side sealing ceramic gate valve is of a compound gate plate structure, namely the ceramic plate and the metal connecting plate are combined, the metal connecting plate bears impact force and does not crack due to impact, the service life is prolonged, and assembly is facilitated.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of one side sealed ceramic gate valve.
Background technique
The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down.In order to adapt to bad working environments, in recent years, the equal Ceramics materials processing of flashboard and valve seat, makes flashboard and valve seat all have the performances such as good resistance to chemical attack, wear-resistant, high temperature resistant, resistance to erosion, and this gate valve is referred to as ceramic gate valve.Existing ceramic gate valve is mainly made up of drive unit, valve body, valve rod, ceramic flashboard and ceramic valve seat, and ceramic valve seat is nested in the protrusion position at flow channels middle part in valve body, and the end face of the ceramic valve seat end face corresponding with ceramic flashboard coordinates, and realizes sealing.Because ceramic flashboard entirety is all to be formed by Machining of Ceramics, there is certain fragility, poor impact resistance, easily cracked, when assembling, will make because of carelessness ceramic flashboard damage.
Model utility content
In order to overcome the ceramic flashboard poor impact resistance of existing ceramic gate valve and easy cracked deficiency, the utility model provides a kind of one side sealed ceramic gate valve, this one side sealed ceramic gate valve adopts compound shutter plate structure, be that ceramic plate combines with metallic interconnect, by metallic interconnect carrying impact force, ceramic plate can not be impacted and cracked, has extended working life, is convenient to assembling.
The technical solution of the utility model is: a kind of one side sealed ceramic gate valve comprises drive unit, valve body, valve rod and ceramic plate, in valve body, be provided with ceramic valve seat, in valve body, be provided with flow channels, one end of flow channels is provided with the tube shape bulge of protrusion, described ceramic valve seat is circular and is nested in outside boss, the exterior edge face of ceramic valve seat is concordant or exceed the end face of boss, between valve rod and ceramic plate, be provided with metallic interconnect, one side of described metallic interconnect is provided with groove, and described ceramic plate is fixed in groove and is affixed with the end face of ceramic valve seat.
Described ceramic plate is embedded in groove and pastes mutually by mighty bond and metallic interconnect.
Described ceramic plate is connected with metallic interconnect by bolt.
Between the periphery of described ceramic plate and groove, be provided with Stamping Steel Ribbon.
The utlity model has following beneficial effect: owing to taking such scheme, ceramic plate and metallic interconnect form compound flashboard, by metallic interconnect carrying impact force, ceramic plate can not be impacted, and ceramic plate just can not be cracked because of impact, extended working life, in the time of assembling, valve rod is connected with metallic interconnect, can not cause ceramic plate to damage in assembly process, assembles also more convenient.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is that in Fig. 1, ceramic plate 4 is tied schematic diagram with the installation of metallic interconnect 8.
1-drive unit in figure, 2-valve body, 3-valve rod, 4-ceramic plate, 5-ceramic valve seat, 6-flow channels, 7-boss, 8-metallic interconnect, 9-groove, 10-Stamping Steel Ribbon.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, a kind of one side sealed ceramic gate valve comprises drive unit 1, valve body 2, valve rod 3 and ceramic plate 4, in valve body 2, be provided with ceramic valve seat 5, in valve body 2, be provided with flow channels 6, one end of flow channels 6 is provided with the tube shape bulge 7 of protrusion, described ceramic valve seat 5 is circular and is nested in outside boss 7, the exterior edge face of ceramic valve seat 5 is concordant or exceed the end face of boss 7, to guarantee that ceramic plate 4 can fit with ceramic valve seat 5, between valve rod 3 and ceramic plate 4, be provided with metallic interconnect 8, one side of described metallic interconnect 8 is provided with groove 9, described ceramic plate 4 is fixed in groove 9 and is affixed with the end face of ceramic valve seat 5.Owing to taking technique scheme, ceramic plate 4 forms compound flashboard with metallic interconnect 8, carry impact force by metallic interconnect 8, ceramic plate 4 can not be impacted, and ceramic plate 4 just can not be cracked because of impact, extended working life, in the time of assembling, valve rod 3 is connected with metallic interconnect 8, can not cause ceramic plate 4 to damage in assembly process, assembles also more convenient.
Described ceramic plate 4 is embedded in groove 9 and pastes mutually by mighty bond and metallic interconnect 8.The means of fixation of pasting by mighty bond, not be used on ceramic plate 4 punching, avoids in punching process ceramic plate 4 cracked.
Described ceramic plate 4 is connected with metallic interconnect 8 by bolt.Ceramic plate 4 is connected reliably with metallic interconnect 8.
Between the periphery of described ceramic plate 4 and groove 9, be provided with Stamping Steel Ribbon 10.Stamping Steel Ribbon 10 seals, and avoids medium to enter in groove 9.
Claims (4)
