Outlet is connected with the inner cavity of expanding chamber end socket, further includes: one, by pressure chamber end socket, is threaded with one on by pressure chamber end socket
A pressure gauge being connected with by pressure chamber end socket inner cavity passes through docking fixed mechanism and expanding chamber end socket by the port of pressure chamber end socket
Port mutually fixed docking, will also pressed to accompanying an energy between the port of pressure chamber end socket and the port of expanding chamber end socket
The flexible sheet with elastic deformation ability that room end socket inner cavity and expanding chamber end socket inner cavity phase resistance separate.
Further, diaphragm type high-temperature burner hearth pressure monitoring device above-mentioned, in which: dock the structure packet of fixed mechanism
Include: two can be fixed on the flange of spelling, a flange by the port of pressure chamber end socket, another flange is fixed on expanding chamber envelope
On the port of head, two flanges by screw bolt and nut to spell it is fixed after can will be by the port of pressure chamber end socket and expanding chamber end socket
Port mutually fixed docking.
Further, diaphragm type high-temperature burner hearth pressure monitoring device above-mentioned, in which: flexible sheet is stainless steel circle wave
Line diaphragm.
Further, diaphragm type high-temperature burner hearth pressure monitoring device above-mentioned, in which: by pressure chamber end socket and expanding chamber end socket
It is half elliptic end socket.
Further, diaphragm type high-temperature burner hearth pressure monitoring device above-mentioned, in which: pressure gauge and pressure monitoring pipe go out
Mouth alignment, and be respectively arranged at the center of each self-sealing head.
Advantages of the present invention are as follows: diaphragm type high-temperature burner hearth pressure monitoring device of the present invention is due to using flexible sheet
Pressure gauge and burner hearth high-temperature gas are separated, so that pressure gauge be made not damage when monitoring pressure；In addition, due to benefit
Burner hearth air pressure is conducted with the deformation of flexible sheet, pressure gauge is enabled to monitor the variation of pressure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of diaphragm type high-temperature burner hearth pressure monitoring device of the present invention.
Fig. 2 is the structural schematic diagram of flexible sheet shown in Fig. 1.
Specific embodiment
The present invention is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 1 and Figure 2, diaphragm type high-temperature burner hearth pressure monitoring device, comprising: mounting plate 1 opens up on mounting plate 1
There is a through-hole 11, the relief tube 2 that an entrance is connected with through-hole 11 on mounting plate 1 is provided on mounting plate 1, in pressure release
A relief valve 21 is threaded in the outlet of pipe 2, the entrance of pressure monitoring pipe 3 is fixed and is connected to 2 phase of relief tube, pressing
An expanding chamber end socket 4, the outlet and the inner cavity phase of expanding chamber end socket 4 of pressure monitoring pipe 3 are provided in the outlet of power monitoring pipe 3
Connection, further includes: one by pressure chamber end socket 5, be half elliptic envelope by pressure chamber end socket 5 and expanding chamber end socket 4 in the present embodiment
Head is threaded with the pressure gauge 51 being connected with by 5 inner cavity of pressure chamber end socket, by pressure chamber end socket 5 on by pressure chamber end socket 5
By docking fixed mechanism and the port of expanding chamber end socket 4, mutually fixation is docked for port, in the present embodiment, pressure gauge 51 and press
Power monitors the outlet alignment of pipe 3, and is respectively arranged at the center of each self-sealing head；By the port of pressure chamber end socket 5 and
It will also be separated by 5 inner cavity of pressure chamber end socket and 4 inner cavity phase resistance of expanding chamber end socket to accompanying an energy between the port of expanding chamber end socket 4
