摘要： A gate valve with linkage structure includes at least a power cylinder, a valve body having a valve opening; a gate assembly in the valve body, having a main gate board and an air-tight gate board neighborly disposed, and connected with one end of the air-tight gate board by at least one parallel linkage; and at least a press bar, with one end pivotally connected to the air-tight gate board and the other end extending to form a press end. A linkage bar is pivotally connected to the press bar and also pivotally connected to the main gate board. Therefore, the gate assembly is driven to seal the valve opening; the air-tight gate board moves away from the main gate board with the linkage function; a sealing force is generated to keep the air-tightness between the air-tight gate board and the valve opening.

摘要： A gate valve includes a valve base, a first piston unit disposed in the valve base and driven by a fluid to move the valve door between a first position where the valve port is opened and a second position where the valve port is covered, a second piston unit disposed in the valve base and driven by the fluid to move the valve door between the second position and a third position where the valve port is sealed, and a valve door fitted to a valve port of the valve base. At least one flow channel switch is disposed in the valve base. When the flow channel switch is turned on, the fluid is allowed to pass through, such that the second piston unit drives accurately the valve door to seal the valve port, thereby achieving purposes of enhancing accuracy in operation and ensuing airproof performance.

摘要： A right angle valve includes a valve body having a cavity, a first pipe and a second pipe connected therewith; a fixing member fixed to the valve body, having a combining end inserted into the cavity; a disc spring having one end combined to the combining end and the other end connected with a sealing member for sealing an inner end of the first pipe; a cover body fixed on one end of the valve body away from the first pipe; a piston member slidingly disposed in the cover body with one end thereof combined to the sealing member, and a covering measure. When the piston member drives the sealing member to move away from the inner end of the first pipe to enable the air flow, the covering measure covers the disc spring, preventing the disc spring from exposure to the flowing air, avoiding an obstruction.

摘要： A double sealing valve includes a power cylinder having a driving axle, a valve body formed of a first and a second valve members, and a seal plate assembly within the valve body. Therein, the first valve member has an axle bore for the driving axle to pass through, and the second valve member has two valve holes oppositely disposed. The seal plate assembly has a driving frame connected to the driving axle, with plural roller assemblies disposed around the driving frame. The seal plate assembly has two seal plates disposed between two faces of the driving frame and the valve body, respectively. Each seal plate has plural driving grooves corresponding to the roller assemblies. The driving axle drives the seal plate assembly to seal the valve holes, with a sealing force produced therebetween by use of the roller assembly and the driving groove.
