Abstract
The utility model relates to a double sealed ceramic brake valve. The double sealed ceramic brake valve mainly solves the problems that an existing ceramic brake valve is poor in shock resistance, prone to fragmenting and poor in sealing performance. The double sealed ceramic brake valve is characterized in that a metal connecting plate (8) is arranged between a valve rod (3) and ceramic plates (4), a valve body (2) is internally provided with a second ceramic valve seat (10) capable of moving, the outer end of the second ceramic valve seat (10) is provided with a leaf spring (11) and a pressing ring (12), and the two ceramic plates (4) are attached to the end face of a first ceramic valve seat (5) and the end face of the second ceramic valve seat (10) respectively. A combined brake plate structure and a double-ceramic valve seat structure are adopted in the double sealed ceramic brake valve, the metal connecting plate is used for bearing impact force, the ceramic plates cannot fragment when impacted, service life is prolonged, assembling is convenient, the back face of the combined brake plate cannot be corroded, operation is stable when the double sealed ceramic brake valve is used, and the sealing effect is good.

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, ceramic valve seat inlays the protrusion position that is enclosed within flow channels middle part in valve body, the end face of the ceramic valve seat end face corresponding with ceramic flashboard coordinates, and realizes sealing.This ceramic gate valve is all generally one side sealing configuration, because ceramic flashboard entirety is all to be formed by Machining of Ceramics, has certain fragility, and poor impact resistance is easily cracked, will make because of carelessness ceramic flashboard damage when assembling.Although and the flashboard that adopts the composite structure of sheet metal and ceramic plate can solve the poor and easy cracked problem of impact, easily corrode at the back side of compound flashboard, causes that flashboard shakes, poor sealing performance.
Model utility content
In order to overcome existing ceramic gate valve poor impact resistance, the easy deficiency of cracked and poor sealing performance, the utility model provides a kind of dual face seals ceramic gate valve, this dual face seals ceramic gate valve adopts compound shutter plate structure and two ceramic valve seat structure, by metallic interconnect carrying impact force, ceramic plate can not be impacted and cracked, has extended working life, be convenient to assembling, the back side of compound flashboard can not be corroded, when use, operates steadily, and good sealing effect.
The technical solution of the utility model is: a kind of dual face seals ceramic gate valve, comprise drive unit, valve body, valve rod and ceramic plate, in valve body, be provided with the first 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, the both sides of described metallic interconnect are equipped with groove, described ceramic plate is two and distinguishes in the groove of fixing metal connecting plate both sides, in valve body, be provided with mobile the second ceramic valve seat, the outer end of the second ceramic valve seat is provided with spring sheet and trim ring, two ceramic plates are affixed with the end face of the first ceramic valve seat and the end face of the second ceramic valve seat respectively.
Described ceramic plate is embedded in groove and pastes mutually by mighty bond and metallic interconnect.
The second described ceramic valve seat is that tubulose and outer wall are provided with stage, and the endoporus on valve body is shoulder hole, and the inserting end of the second ceramic valve seat protrudes.
Described drive unit is electronic and hydraulic combined drive unit.
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, extend working life, two ceramic plates are fitted with the first ceramic valve seat and the second ceramic valve seat respectively, form dual face seals, spring sheet redeeming, make sealing surface laminating tightr, good sealing effect.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.Because the back side of compound flashboard can not be corroded, when use, operate steadily.
