Summary of the invention
Technical problem to be solved in the utility model is that overcoming long the causing in connecting pipe of reactor the 4th bed liquid level pressure connecting pipe easily occurs bubble, cause instruction deviation and fluctuation, the high pressure bed liquid level emasuring device that the steady rate of a kind of liquid level is high, structure is simple, esy to use, safe and reliable is provided.
Solving the problems of the technologies described above adopted technical scheme is: on the malleation inlet duct of differential pressure transmitter, be provided with malleation sealing chamber liquid feed valve, the malleation end outlet conduit of differential pressure transmitter is provided with malleation atmospheric valve, negative pressure end one outlet conduit of differential pressure transmitter is provided with negative pressure atmospheric valve, another outlet of the negative pressure end of differential pressure transmitter is connected by the entrance being arranged on negative pressure sealing chamber liquid valve on pipeline and negative pressure sealing chamber, negative pressure sealing chamber is provided with negative pressure sealing chamber vent valve, the outlet conduit of negative pressure sealing chamber is provided with negative pressure sealing chamber liquid feed valve, the malleation inlet duct of differential pressure transmitter and malleation sealing chamber liquid feed valve is provided with malleation sealing chamber liquid valve and malleation sealing chamber, the entrance of malleation sealing chamber is connected by pipeline and malleation sealing chamber liquid feed valve, the malleation entrance exported by being arranged on malleation sealing chamber liquid valve on pipeline and differential pressure transmitter is connected, malleation sealing chamber is provided with malleation sealing chamber vent valve.
The utility model installs malleation sealing chamber and malleation sealing chamber liquid feed valve additional after malleation liquid feed valve, spacer pad is filled with in malleation sealing chamber, solve in the connecting pipe caused because connecting pipe is long and produce bubble and cause instruction deviation and wave phenomenon, malleation sealing chamber is provided with malleation sealing chamber vent valve, when carrying out buying spacer pad, discharges air.The utility model enhances the steady rate of liquid level, decreases connecting pipe blocking, easily carries out the inspection that differential pressure send device variation tendency, have the advantages such as structure is simple, esy to use, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to these embodiments.
Embodiment 1
In FIG, the high pressure bed liquid level emasuring device of the present embodiment is made up of negative pressure sealing chamber liquid valve 1, negative pressure sealing chamber vent valve 2, negative pressure sealing chamber 3, negative pressure sealing chamber liquid feed valve 4, malleation sealing chamber vent valve 5, malleation sealing chamber liquid feed valve 6, malleation sealing chamber 7, malleation sealing chamber liquid valve 8, differential pressure transmitter 9, malleation atmospheric valve 10, negative pressure atmospheric valve 11 connection.
In the present embodiment, the entrance of malleation sealing chamber 7 is provided with malleation sealing chamber liquid feed valve 6 by thread connection, malleation sealing chamber 7 is provided with malleation sealing chamber vent valve 5 by thread connection, whether malleation sealing chamber vent valve 5 has air for checking in malleation sealing chamber 7, and the air in malleation sealing chamber 7 is discharged, another outlet of malleation sealing chamber 7 is connected with differential pressure transmitter 9 malleation end entrance by the malleation sealing chamber liquid valve 8 be arranged on pipeline, spacer pad is filled with in malleation sealing chamber, solve in the connecting pipe caused because connecting pipe is long and produce bubble and cause instruction deviation and wave phenomenon.The malleation end outlet conduit of differential pressure transmitter 9 is provided with malleation atmospheric valve 10, emit with the liquid in the positive pressure side duct coupling of differential pressure transmitter 9 under off working state or the emergency circumstance, negative pressure end one outlet conduit of differential pressure transmitter 9 is provided with negative pressure atmospheric valve 11, emits with the liquid in differential pressure transmitter 9 negative pressure end duct coupling under off working state or the emergency circumstance.Another outlet of the negative pressure end of differential pressure transmitter 9 is connected with the entrance of negative pressure sealing chamber 3 by the negative pressure sealing chamber liquid valve 1 be arranged on pipeline, negative pressure sealing chamber 3 is threaded connection negative pressure sealing chamber vent valve 2 is installed, negative pressure sealing chamber vent valve 2 checks whether have air in negative pressure sealing chamber 3, and the air in negative pressure sealing chamber 3 is discharged, the outlet conduit of negative pressure sealing chamber 3 is provided with negative pressure sealing chamber liquid feed valve 4 by thread connection.The pressure that positive pressure side and negative pressure end send experienced by differential pressure transmitter 9 simultaneously, can carry out the level gauging of high pressure bed when the pressure of the positive pressure side of differential pressure transmitter 9 is greater than negative pressure end pressure, differential pressure transmitter 9 can be used for preventing ducted high-pressure diesel from having hydrogen to be precipitated simultaneously.Be installed in the negative pressure sealing chamber 3 after negative pressure sealing chamber liquid feed valve 4 and malleation sealing chamber liquid feed valve 6 and malleation sealing chamber 7 and spacer pad is housed, solve the phenomenon producing bubble because connecting pipe is long wherein, make liquid fluctuating keep stable by periodic replacement spacer pad, strengthen the steady rate of liquid level.
