Embodiment Construction
[0009] SF 6 Inflatable tube quick opening valve, such as figure 1 , figure 2 As shown, the ball valve 1 is included, the valve stem 2 of the ball valve 1 is provided with an upper lever 5 and a lower lever 6 perpendicular to the valve stem 2, and the upper lever 5 and the lower lever 6 are perpendicular to each other. Ball valve 1 is opened and closed by rotating the valve stem 2, and the valve stem 2 can be rotated 90° to complete the full opening and closing of the ball valve 1, avoiding the phenomenon that the multi-turn rotation cannot be opened and closed, and the operation is simple and flexible. The valve port of the ball valve 1 is connected to the auxiliary valve, and the two valves realize double valve control, which increases the safety guarantee factor and has double guarantees. Auxiliary valve comprises valve body 17, offers upper push rod groove 14, lower push rod groove 13, air passage 26, connecting pipe groove 23 and pressure plate groove 34 on valve body 1...

The invention discloses a quick opening valve of an SF6 gas charging tube. The quick opening valve of the SF6 gas charging tube comprises a ball valve and an auxiliary valve. The auxiliary valve comprises a valve body. When a gas charging valve and a gas charging tube fall off, or the gas charging tube cracks or other accidents happen, the ball valve is closed quickly, SF6 gas is blocked, and safety of production is ensured. After the valve is closed, double safety protection is achieved through two closure points; the ball valve and the auxiliary valve are matched mutually to achieve the synchronous opening and closing state, one valve is controlled to finish the opening and closing action of the two valves, and synchronous opening and closing improves the safety of various parts; all structures are matched flexibly, each position is provided with a reset device, operation of each step is timely and accurate, the opening and closing process is smooth, the clamping phenomenon is avoided, safety and stability are ensured, a connection tube can be assembled and disassembled rapidly, and usage is convenient.
Description
technical field [0001] The present invention relates to a valve, specifically a SF 6 The inflatable tube opens the valve quickly. Background technique [0002] Existing SF 6 The inflation valve and the inflation tube of the gas tank are directly fixed, and the temperature will change sharply during the electrified gas supply process, which may cause accidents such as the inflation valve and the inflation tube falling off, and the inflation tube rupture, which poses a major safety hazard. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a kind of SF 6 The inflatable tube opens the valve quickly. [0004] In order to achieve the above object, the present invention is realized through the following technical solutions: SF 6 Inflatable tube quick-opening valves, including ball valves, the valve stem of the ball valve is provided with an upper lever and a lower lever perpendicular to t...
