一种新型高寿命压力容器

Abstract

本实用新型涉及压力容器技术领域，公开了一种新型高寿命压力容器，本实用新型包括一个压力罐体，其中在所述压力罐体顶部固定设有压力罐法兰头，还包括减震式连接管和压盘；其中所述减震式连接管上分别设有螺牙结构以及由橡胶制成的密封结构，所述压盘通过螺栓固定在所述压力罐法兰头上并将所述减震式连接管上的橡胶密封结构部分紧压入所述压力罐法兰头内，通过所述橡胶密封结构以及所述压力罐法兰头和所述减震式连接管形成的螺旋副实现双重密封。本装置通过对排气口位置结构的重新设计，采用分体式配合，利用螺纹密封并增加密封填充结构实现加强密封并进行减振，有效的降低了该处排气时振动对金属焊接结构以及密封接触结构的影响。

Claims

1. A novel high-life pressure vessel, comprising a pressure tank body (10), wherein a pressure tank flange (18) is fixedly provided on the top of the pressure tank body (10), and further comprising a shock-absorbing connecting pipe (19) and a pressure plate (11); characterized in that: The shock-absorbing connecting pipe (19) is provided with a threaded structure and a sealing structure made of rubber. The pressure plate (11) is fixed to the pressure tank flange (18) by bolts and the rubber sealing structure on the shock-absorbing connecting pipe (19) is pressed tightly into the pressure tank flange (18). Double sealing is achieved through the rubber sealing structure and the spiral pair formed by the pressure tank flange (18) and the shock-absorbing connecting pipe (19).

2. A new high life pressure vessel as claimed in claim 1, wherein: The shock-absorbing connecting pipe (19) includes an air pipe (16) and a thread (17). The thread (17) is fixed to the outside of the air pipe (16), and the thread (17) is threadedly sealed to the sealing connection thread hole (20) in the pressure tank flange (18).

3. A novel high life pressure vessel as claimed in claim 2, wherein: The lower end of the trachea (16) extends into the pressure vessel (10) and maintains a distance of at least five centimeters from the inner wall of the pressure vessel (10).

4. A novel high life pressure vessel as claimed in claim 3 wherein: The air pipe (16) is fitted with a shock-absorbing filler (15) on the outside. A tapered countersunk hole (22) is provided in the flange head (18) of the pressure tank. The shock-absorbing filler (15) is filled into the tapered countersunk hole (22) under the pressure of the pressure plate (11) and forms a sealed contact with it.

5. A novel high life pressure vessel as claimed in claim 4, wherein: The pressure plate (11) has pressure fingers (12) fixedly spaced in the inner ring. The pressure fingers (12) press against the upper end face of the shock-absorbing filler (15). The pressure plate (11) and the pressure tank flange (18) are provided with bolt holes (13) spaced apart. The bolt holes (13) are fixed together by bolts.

6. A novel high life pressure vessel as claimed in claim 5 wherein: The torque required to tighten the shock-absorbing connecting pipe (19) is AN, the downward pressure of the pressure plate (11) on the shock-absorbing filler (15) is BN, and BN is 1.2 to 1.5 times AN.
