Description

A kind of liquid level, temperature monitoring and pressure release set composite
Technical field
The invention belongs to gauge check field, and in particular to a kind of liquid level, temperature monitoring and pressure release set composite.
Background technology
With the fast development of modern industry, various sealing containers and equipment are used widely, liquid in container or equipment The level sensing of body, limit liquid level alarm, temperature monitoring, superpressure such as are automatically releasable at the status monitoring and automatic fault treatment is weighed very much Will.
When closed container or device interior failure or during the great change of external environment condition, internal temperature is caused to rise, and then The liquid expansion for bringing and headspace are compressed, it is also possible to a large amount of gases are produced in container or equipment, container may be all caused Or device interior pressure exceedes vessel safety pressure, if pressure can not discharge and alarm in time, it is entirely by strong influence The safety of system.
The sensor monitoring product of prior art is difficult to meet modern combined monitoring and system protection demand, such as in many fields Conjunction is required for monitoring fluid temperature and liquid level, works as the system failure(Such as, the internal component short circuit of container to be monitored or equipment)Or External environment condition drastically changes(Fire), fluid temperature rising brings inside liquid level to rise and pressure increase in sealing container so that Container has risk of explosion, is badly in need of overpressure relief.
Tradition is commonly installed 2 sensors for the oil level and temperature of transformer oil in monitoring oil tank of transformer, is respectively used to Monitoring oil level and oil temperature;For the gas that release transformer longtime running is produced in fuel tank installs pressure relief valve in tank wall, this It is accomplished by opening three mounting holes on oil tank of transformer.And due to temperature sensor fixed installation, fixed position can only be monitored Oil temperature, for the temperature highest top layer more difficult monitoring of oil level temperature.
Therefore, exploitation one kind can intuitively show liquid level, limit liquid level alarm, while top layer fluid temperature can be monitored, and energy The combined monitoring protection device that superpressure is automatically releasable is very necessary.
The content of the invention
It is an object of the invention to provide a kind of novel liquid level, temperature monitoring and pressure release set composite, intuitively showing Liquid level, limit liquid level can conveniently monitor top layer fluid temperature while alarm, again can be when internal system pressure exceedes safety value It is automatically releasable internal pressure.
In order to achieve the above object, the invention provides a kind of liquid level, temperature monitoring and pressure release set composite, this is answered Attach together to put and include:
