Problems solved by technology

If pneumatic control is used, an additional instrument air source needs to be added to the fuel cell system. When using traditional electric and electromagnetic regulating valves, the response speed is too slow compared to fuel system control

Embodiment 1

[0015] Embodiment 1 (the valve stem 6 is fixed, and the seal 5 can slide on the valve stem 6)

[0016] like figure 1 As shown, the present invention includes a tailpipe 1 and a valve stem support frame 2 and a valve seat 3 inside it, and the tailpipe 1 is a 90° elbow. There is a hole on the valve seat 3, and a valve cover 8 is arranged on the side wall of the exhaust pipe 1. One end of the valve stem 6 is connected to the valve stem support frame 2 through the hole of the valve seat 3, and the other end is connected to the valve cover 8. The valve stem 6 is covered with a seal 5 and a spring 7, the seal 5 is inlaid with a sleeve 4, the sleeve 4 can slide on the valve stem 6, and the seal 5 is sleeved on the valve stem 6 through the sleeve 4.

[0017] First, at the lowest flow rate, the spring 7 stretches so that the seal 5 sticks to the hole on the valve seat 3, and the valve port is in a closed state. When the air flow rate increases, the resistance through the valve increas...

Embodiment 2

[0018] Embodiment 2 (the seal 5 and the valve stem 6 are integrally structured, and the valve stem 6 can slide)

[0019] like figure 2 As shown, the initial position of the spring 7 is adjustable. The invention comprises a tailpipe 1 and a valve stem support frame 2 and a valve seat 3 arranged inside it, and the tailpipe 1 is a 90° elbow. The valve seat 3 has a hole, the side wall of the exhaust pipe 1 is provided with a valve cover 8, the valve cover 8 is connected with an adjustment handle 9, and the valve stem 6 is connected to the valve stem support frame 2 through the hole of the valve seat 3 , the other end passes through the adjustment handle 9, an "O" ring 10 is added between the valve stem 6 and the adjustment handle 9, the valve stem 6 is covered with a seal 5 and a spring 7, and the seal 5 and the valve stem 6 are integrated. A fixed baffle 11 is provided on the valve stem 6 and one side of the seal 5 .

[0020] First, at the lowest flow rate, rotate the adjustm...

Abstract

The invention consists of ending comb, valve handle carriage and valve seat. A hole is opened at the valve seat. The valve cap is set on the side wall of ending comb. The one end of valve handle is connected with the valve handle carriage through the hole opened on the valve seat. The other end is connected with valve cap. A seal and spring cover on the valve handle. The ending comb is 90deg bend pipe. A sliding sleeve is set inside the seal. The seal covers on the valve handle through the sleeve. One end of seal has a fixed dam. A regulating handle is connected with valve cap. One end of valve handle is connected with the valve handle carriage. The other end drills through the regulating handle. A 'O' shaped ring is set between the valve handle and regulating handle.

Description

technical field [0001] The invention relates to a regulating device, in particular to a large-flow mechanical tail gas automatic regulating device for a fuel cell engine system used for regulating the pressure of a fuel cell system. Background technique [0002] The fuel cell converts chemical energy into electrical energy according to the electrochemical principle. When it is working, fuel and oxidant (such as hydrogen and oxygen) must be continuously fed into the battery, and at the same time, equimolar reaction product water must be discharged. The supply of oxidant generally adopts pure oxygen or air. When air is used as oxidant, there are two ways to supply air. One is to use a fan or fan to supply air at normal pressure, and the other is to use a pressurized air compressor to supply air. Generally, the operation mode of fuel cell system is constant pressure operation mode and variable pressure operation mode. [0003] Whether it is constant pressure operation or varia...
