Problems solved by technology
At present, it is the period of rapid development of China's urban rail transit. Dozens of large and medium-sized cities have opened subways. On these completed subway lines, many domestic combination valves have more or less problems. For example, the strength of blades, blade shafts, and valve frames is not enough, and the sealing materials do not meet the requirements of national regulations, etc., and tunnel industrial valves are also required in the fields of nuclear energy, chemical industry, and marine transportation. Long, wide application, high sealing tunnel industrial valve

The invention discloses a tunnel industrial valve. The tunnel industrial valve comprises a valve body and a plurality of parallel blades; corner joints of the valve body are subjected to full weld from the outer side, one side of the valve body is provided with a connection rod mechanism, and a plurality of flange bearings are arranged on the two sides of the valve body and fixed through locking clamping rings; short shafts are arranged on the flange bearings, and one ends of the short shafts are connected to the connection rod mechanism; each blade comprises two anti-symmetrical single bladebodies, the longitudinal edges of the two single blade bodies are fixedly connected, a rhombic groove formed by combining the two single blade bodies is formed in the blade, open grooves are formed inthe two sides of the blade by combining the two single blade bodies, and ceramic fiber sealing ropes are arranged in the open grooves; the other ends of the short shafts are fixed into the grooves; and the connection rod mechanism drives the blades to rotate through the short shafts. The tunnel industrial valve is high in strength, resistant to high temperature, long in service life, wide in application range and high in sealing performance, and is applied to severe working conditions of tunnel ventilation, nuclear energy, chemical engineering, sea transportation and the like.
Description
technical field [0001] The invention belongs to the technical field of industrial valves, and in particular relates to a tunnel industrial valve. Background technique [0002] Tunnel industrial valves are used for fire protection, containment, balancing and smoke control / exhaust etc. At present, it is the period of rapid development of China's urban rail transit. Dozens of large and medium-sized cities have opened subways. On these completed subway lines, many domestic combination valves have more or less problems. For example, the strength of blades, blade shafts, and valve frames is not enough, and the sealing materials do not meet the requirements of national regulations, etc., and tunnel industrial valves are also required in the fields of nuclear energy, chemical industry, and marine transportation. Long, wide application, high sealing tunnel industrial valve. Contents of the invention [0003] The object of the present invention is to provide a tunnel industrial va...
