Abstract
The utility model is applied to a fully-closed liquid system and relates to a modified compensator for a fully-closed liquid circulation system. The modified compensator comprises a tank body, a liquid discharge switch, a liquid level view device and a liquid level measuring device, wherein the tank body has a cavity; the liquid level measuring device, a liquid feed port, a safety valve and a vacuum-prevention valve are arranged at the upper part of the tank body; the liquid discharge switch is arranged at the lower part of the tank body; a connector for external connection is arranged at thelower part of the tank body; and the liquid level view device is arranged on one side of the tank body. The compensator is mounted at the peak of the whole liquid system in a way that the lower connector is connected with the system. During the operating process, the gas or steam generated by the system enters the tank body through the pipeline, and the safety valve and the vacuum-prevention valveon the compensator are used for keeping the pressure of the space above the liquid in the tank body within a certain range. The compensator provides the fully-closed liquid system with the volume compensation space of the fluid medium and the air/steam pressure impact balance.
Description
Technical field
The utility model is used for totally-enclosed liquid system, relates to the improvement to existing totally-enclosed fluid circulation system compensator.
Background technique
In totally-enclosed fluid circulation system, at present, being widely used in expansion tank of using on water tower on the water system or the automobile etc. can compensate in its place system, " expanding with heat and contract with cold " caused Volume Changes of liquid medium, but when system operation has when necessarily requiring the pressure surge scope, this type of device can't satisfy the user demand of system.
In totally-enclosed liquid system that the pressure surge scope is had certain requirements, in the totally-enclosed liquid system that particularly uses on the aircraft, be in operation hypotony that the air that produces or steam causes system or too highly will cause running efficiency of system to reduce or fault can't be moved of system.Secondly, totally-enclosed liquid system mainly relies on liquid pump to realize the flow of fluid circulation, and the bigger variation of pressure surge scope also will cause liquid pump that " cavitation erosion " phenomenon takes place, and makes system's forfeiture power source, can't work.
Summary of the invention
The purpose of this utility model be propose a kind of in totally-enclosed liquid system, system's hypotony that the air that produces or steam causes or too high that is in operation, a kind of totally-enclosed fluid circulation system compensator that system still can normally move.Technical solution of the present utility model is, totally-enclosed fluid circulation system compensator, comprise casing, tapping switch, liquid level finder, liquid level emasuring device, casing is a cavity, liquid level emasuring device, filling opening, safety valve and anti-vacuum valve are equipped with in the top of casing, the connection mouth that the bottom of casing is equipped with the tapping switch and is connected with the outside, the liquid level finder places a side of casing.
Advantage that the utlity model has and good effect, the utility model is installed in the peak of whole liquid system, the bottom connection mouth is connected with system, causes when expanding with heat and contract with cold when liquid volume changes in the system, and compensator is realized the storage of liquid by this interface or replenished; In running, gas that system produces or steam also can be thus connected mouth and enter in the casing, the pressure that safety valve on the compensator and anti-vacuum valve are used to guarantee liquid upper space in the casing within the specific limits, the liquid level finder is used to observe the height of liquid level in the casing, and liquid level emasuring device can provide the high-low signal of liquid level in the casing simultaneously.Tapping switch and filling opening use when being used for the liquid of emptying compensator or liquid filling.Provide the volume compensation space of a flowing medium and the device of air or vapor pressure impact balance to totally-enclosed liquid system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Totally-enclosed fluid circulation system compensator is made up of casing 1, tapping switch 2, liquid level finder 4, liquid level emasuring device 5, safety valve 7 and anti-vacuum valve 8, and filling opening 6 and the connection mouth 3 that is connected with system are arranged on the casing 1.Casing 1 is a cavity, and liquid level emasuring device 5, filling opening 6, safety valve 7 and anti-vacuum valve 8 are equipped with in the top of casing 1, the connection mouth 3 that the bottom of casing 1 is equipped with tapping switch 2 and is connected with the outside, and liquid level finder 4 places a side of casing.
During use, certain amount of fluid is arranged at casing 1 bottom, and top is gas, when temperature raises expansion, excess liquid is entered in the casing 1 by connection mouth 3 in the system, simultaneously, the gas that produces when moving in system also can be thus connected mouth 3 and enter casing 1, in order not cause the fluctuation of system pressure, when casing 1 internal pressure is too high, safety valve 7 is opened venting, crosses when low when casing 1 internal pressure, and anti-vacuum valve 8 is opened tonifying Qi in casing 1.In when maintenance, by the liquid of tapping switch 2 in can emptying casing 1.The liquid level finder is used to observe the height of liquid level in the casing 1, when needing to replenish small amount of liquid, the filling opening filling can be arranged.Liquid level emasuring device can provide the altitude signal of liquid level in the casing 1, is used for system's liquid level indication.
