Embodiment Construction

[0008] refer to figure 1 , the specific embodiment adopts the following technical solutions: a new type of pneumatic flat gate valve, including a frame 1, a gate 2 and a cylinder 3, the frame 1 is provided with a gate 2, and the top of the gate 2 is connected to the piston rod 4 The bottom end of the piston rod 4 is fixedly connected, and the top end of the piston rod 4 is bolted to the cylinder 3 .

[0009] The connection between the cylinder 3 and the piston rod 4 is provided with a rubber sealing ring to increase the sealing effect.

[0010] refer to figure 1 , when this specific embodiment is working, due to the pressure change of the gas in the cylinder 3, the piston rod 4 drives the gate plate 2 to reciprocate in the vertical direction, so as to achieve the purpose of opening and closing the valve.

[0011] Finally, it is noted that the above embodiments are only used to illustrate the technical solution of the present invention without limitation, other modifications ...

Abstract

The invention discloses a novel pneumatic flat gate valve, and relates to the field of gate valve devices. The novel pneumatic flat gate valve comprises a framework, a gate and an air cylinder. The gate is arranged in the framework; the top end of the gate is fixedly connected with the bottom end of a piston rod; and the top end of the piston rod is connected with the air cylinder through bolts. The novel pneumatic flat gate valve has the characteristics of simple structure, convenience in operation, good performances, reliable quality, long service life and the like, is widely applied to flow control and pipelines of dust material in industries of metallurgy, mining, building materials and the like, and is ideal equipment with rapid starting and stopping control requirements.

Description

technical field [0001] The invention relates to the field of gate valve devices, in particular to a novel pneumatic flat gate valve. Background technique [0002] At present, there are usually three types of slab gate valves: manual slab gate valve, electric slab gate valve and pneumatic slab gate valve. However, the existing slab gate valve has the following problems: 1. The structure is complicated, 2. The operation is inconvenient, and 3. The service life is short. Contents of the invention [0003] The purpose of the present invention is to provide a new pneumatic flat gate valve with simple structure, convenient operation and long service life. [0004] In order to solve the existing problems in the background technology, the present invention adopts the following technical solutions: a novel pneumatic slab gate valve, including a frame, a gate and a cylinder, a gate is arranged in the frame, and the top of the gate and the piston rod The bottom end of the piston ro...
