Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
A kind of live constant pressure arrangement of safety valve as shown in Figure 1, 2, including：
Frame, frame includes level table 10, the side bracket 11 being connected on level table 10, support level table top 10
Supporting leg 12；
Jump help tank 2, is arranged on level table 10, the Lift for improving safety valve, and jump help tank 2 can be using such as
The gas tank of the doctrine of equivalents such as Constant pressure tank；
Adpting flange 3, is arranged on jump help tank 2, for connection safety valve, adpting flange 3 can dismantle be arranged on help
Jump on tank 2, according to different safety valves, the adpting flange 3 of different size can be installed；
Pressure gauge 4, is arranged in side bracket 11, in the present embodiment, and pressure gauge 4 is provided with two；
Source of the gas, such as gas source bottle 5.
Gas source bottle 5, jump help tank 2 and pressure gauge 4 are interconnected by connecting pipe respectively, and control is provided with connecting pipe
Valve processed.In the present embodiment：Connecting pipe includes three-limb tube 60, is connected between gas source bottle 5 and three-limb tube 60
Inlet pipe connection 61, the jump help tank connecting tube 62 being connected between three-limb tube 60 and jump help tank 2, it is connected to three-limb tube
It is used to control the intake valve 70 whether it ventilates on pressure gauge connecting tube 63 between 60 and pressure gauge 4, inlet pipe connection 61.Even
