Abstract
The utility model discloses a ceramic seal gate valve with double gate plates, which comprises a valve seat, gate plates and a valve plate track which are arranged in a valve cavity of the valve seat and are driven to open and close by a valve rod, wherein the contact surfaces of a sealing pair composed of an inlet and an outlet of the valve seat and the valve plates are respectively provided with antiwear layers made of ceramic materials. The utility model has the advantages that because the contact surfaces of the sealing pair composed of the inlet and the outlet of the valve seat and the valve plates and the surface of the valve plate track are respectively provided with the ceramic antiwear layers, the double gate plates are used for simultaneously closing the inlet and the outlet of the valve seat when the gate valve is closed, thereby, the sealing effect is enhanced when the gate valve with double gate plates is in a closed state, and the working reliability of the gate valve is improved; the arrangement of the ceramic antiwear layers causes the service life of the gate valve with double gate plates to be improved by more than 10 times; the contact surfaces of pressure springs of the valve plates and the valve plates are changed into spherical surfaces, so the gate plates forcibly and automatically align in an axial direction when the gate plates are closed; the defect that the sealing surfaces can not automatically inosculate because the existing plane surfaces are contacted is overcome, and the sealing effect of the gate plates is further improved.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of ceramic seal double-flashboard gate valve.
Background technique
Be used for the gate valve on the industry cleaning shaft such as power station at present, owing to be subjected to working environment institute extremely, flashboard is in frequent opening-closing process, and the sealing pair surface of contact of valve seat mouth and valve plate composition usually weares and teares in use for some time and causes poorly sealed.This has not only shortened the working life of gate valve, and valve seal does not sternly easily cause the generation of out-of-control phenomenon yet simultaneously, has directly influenced the carrying out of ordinary production.
Summary of the invention
The utility model purpose provides the ceramic seal double-flashboard gate valve of a kind of long service life, good sealing effect.
For achieving the above object, the utility model can be taked following technical proposals:
Ceramic seal double-flashboard gate valve described in the utility model, it comprises valve seat, be arranged on flashboard and valve plate track in the described valve seat valve pocket, on the sealing pair surface of contact of described valve seat inlet/outlet and valve plate composition, be respectively arranged with the wearing layer that stupalith is made by valve rod drive keying.
Be provided with the wearing layer that stupalith is made at described valve plate raceway surface.
The valve plate pressure spring and the valve plate surface of contact that are arranged on the described valve rod are sphere.
Advantage of the present utility model is to be respectively arranged with ceramic wearing coat at the sealing pair surface of contact and the valve plate raceway surface of described valve seat inlet/outlet and valve plate composition, and when closing, take on gate valve the bivalve plate that the valve seat inlet/outlet is closed simultaneously, thereby improved the sealing effect when double-flashboard gate valve is in closed condition greatly, improved the gate valve functional reliability; The setting of ceramic wearing coat makes improve more than 10 times the working life of double-flashboard gate valve; Valve plate pressure spring and valve plate surface of contact are improved to sphere, and the flashboard self-aligning of can axially exerting oneself when closure has overcome the defective that sealing surface that existing plane contact causes can not coincide automatically like this, has further improved the sealing effect of flashboard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I-I portion partial enlarged drawing of Fig. 1.
Embodiment
As shown in the figure, ceramic seal double-flashboard gate valve described in the utility model, comprise valve seat 1, be arranged on flashboard 3 and valve plate track 4 in described valve seat 1 valve pocket, be respectively arranged with the wearing layer that stupalith is made on the sealing pair surface of contact and valve plate track 4 surfaces of described valve seat 1 inlet/outlet and valve plate 3 compositions by valve rod 2 drive keyings.The valve plate pressure spring 5 that is arranged on the described valve rod 2 is a sphere 6 with valve plate 3 surface of contact.
