Abstract
The utility model discloses a ceramic ash discharge gate valve which consists of a valve seat, a valve plate, a ceramic sealing pair and a transmission system. The valve plate is driven to move by the transmission system to implement opening and closing of the valve; the ceramic sealing pair comprises a ceramic sealing ring; the ceramic sealing ring is fixed on the valve plate or the valve seat by a metal pressure ring; the ceramic sealing ring is of a circular ring shape; the outside of the section of the ceramic sealing ring is of a step shape; the metal pressure ring is of a circular ring shape; the inside of the section of the metal pressure ring is of a step shape; and the metal pressure ring is arranged on the ceramic sealing ring in a sleeving manner. The ceramic ash discharge gate valve solves the problem of connection between the ceramic sealing ring and the metal valve seat as well as the valve plate in a high temperature state or under the working condition of large temperature difference variation and makes up the defect of ceramic adhesive bonding.
Description
Technical field
The utility model relates to a kind of valve, and specifically a kind of pottery unloads grey gate valve.
Background technique
Gate valve refers to that valve plate is driven by valve rod, makes the valve of lifting or side-to-side movement, can with electronic, pneumatic, surge and the mode such as manual drives gate valve plate, open or block the passage of fluid.When valve portion is divided unlatching, at the flashboard back side, produce eddy current, easily cause erosion and the vibrations of flashboard, also fragile sealing surface of seat, repairs difficulty.Gate valve is applicable to not need frequent keying conventionally, and keeps the operating mode of flashboard standard-sized sheet or full cut-off, is not suitable as and regulates or throttling use.Pottery unloads grey gate valve, it is characterized in that replacing with ceramic seal face assembly the pile-up welding hard alloy sealing surface of common gate valve.But existing pottery unloads grey gate valve, and cavity body structure is little, the easy dust stratification of valve body, causes adverse effect to the operation of valve plate, easily causes the fault of transmission system.Existing pottery unloads grey gate valve, ceramic seal circle be being connected of valve plate, valve seat gluing inserted, it is high and change large occasion that this Placement is used in medium temperature, and the difference due to expansion coefficient between iron and pottery, the phenomenon that porcelain ring comes unglued and comes off easily occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of pottery and unloads grey gate valve, the Placement of ceramic seal circle and valve plate or valve seat is changed into machinery type and compress, to guarantee that ceramic-seal ring can not come off under any situation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of pottery unloads grey gate valve, by valve seat, valve plate, ceramic seal pair and transmission system, formed, by transmission system, drive valve plate to move, realize the keying of valve, described ceramic seal pair comprises ceramic seal circle, and described ceramic seal circle is fixed on valve plate or valve seat by metal pressure ring.
Described ceramic seal circle is circular, and stepped outside cross section, described metal pressure ring is circular, and stepped inside cross section, metal crimp ring set is loaded on ceramic seal circle.
The beneficial effects of the utility model are:
The utility model has solved under the condition of high temperature or the large working condition of difference variation, and the connectivity problem of ceramic seal circle and metal seat valve, valve plate, has made up the bonding defect of ceramic glue.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve seat; 2, metal pressure ring; 3, ceramic seal circle.
Embodiment
A kind of pottery unloads grey gate valve, by valve seat 1, valve plate, ceramic seal pair and transmission system, formed, by transmission system, drive valve plate to move, realize the keying of valve, described ceramic seal pair comprises ceramic seal circle 3, and described ceramic seal circle 3 is fixed on valve plate or valve seat by metal pressure ring 2.
Described ceramic seal circle 3 is circular, and stepped outside cross section, described metal pressure ring 2 is circular, and stepped inside cross section, metal pressure ring 2 is set on ceramic seal circle 3.
Valve body adopts large cavity, square chest type structure, unload ash unobstructed, without jam.
Specific embodiment comprises following three kinds of forms: on described valve seat 1, valve plate, all use fixedly ceramic seal circle 3 of metal pressure ring 2; On described valve seat 1 with the fixing ceramic seal circle 3 of metal pressure ring 2, fixing ceramic seal circle otherwise on valve plate; On described valve plate with the fixing ceramic seal circle 3 of metal pressure ring 2, fixing porcelain ring otherwise on valve seat.
Disclosed is above only the specific embodiment of this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, is not departing under the prerequisite of the utility model principle, and the distortion of making should be considered as belonging to the utility model protection domain.
Claims (2)
1. a pottery unloads grey gate valve, by valve seat, valve plate, ceramic seal pair and transmission system, formed, by transmission system, drive valve plate to move, realize the keying of valve, it is characterized in that: described ceramic seal pair comprises ceramic seal circle, described ceramic seal circle is fixed on valve plate or valve seat by metal pressure ring.
2. a kind of pottery according to claim 1 unloads grey gate valve, it is characterized in that: described ceramic seal circle is circular, and stepped outside cross section, described metal pressure ring is circular, and stepped inside cross section, metal crimp ring set is loaded on ceramic seal circle.
