Description

Vacuum buffer tank capable of preventing hose from being blocked

Technical Field

The utility model belongs to the technical field of the vacuum buffering, concretely relates to can prevent vacuum buffer tank of hose jam.

Background

The buffer tank is mainly used for buffering pressure fluctuation of the system in various systems, so that the system works more stably. The buffer tank has two kinds of diaphragm type buffer tank and air bag type, and is widely applied to water supply equipment, central air conditioning system and other things, and the buffer tank is widely applied to central air conditioning, boilers, water heaters, frequency conversion, and constant pressure water supply equipment, and the pressure fluctuation of the buffer system eliminates the water hammer to play the effect of steady voltage unloading, and when the water pressure in the system slightly changes, the automatic expansion and contraction of the air bag of the buffer tank can have certain buffering effect on the change of the water pressure, and can ensure the stability of the water pressure of the system, and the water pump can not be frequently opened due to the change of the pressure.

At present, realize indoor, the unable installation manometer of miniature reation kettle, real-time vacuum can't accurate understanding during the evacuation, easy suck-back during vacuum pump pressure release simultaneously brings very big inconvenience for the use.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a can prevent vacuum buffer tank of hose jam, includes erlenmeyer flask and vacuum pressure gauge, the top port department of erlenmeyer flask is provided with vacuum pressure gauge, one side of erlenmeyer flask is provided with first hose, the one end intercommunication of first hose has first PVC hard tube, the opposite side of erlenmeyer flask is provided with the second hose, the one end intercommunication of second hose has second PVC hard tube.

Preferably, the first hose and the second hose are both rubber hoses.

Preferably, the other end of the first PVC hard pipe is connected with a reaction kettle, and the other end of the second PVC hard pipe is connected with a vacuum pump.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model can monitor the vacuum degree in the reaction kettle and the conical flask in real time by arranging the vacuum pressure gauge, thereby facilitating the experimenter to accurately know the real-time vacuum degree, the first PVC hard pipe and the second PVC hard pipe have better extensibility and are not easy to damage and block, and are convenient for connecting the devices, the device adopts the vacuum pressure gauge and the conical flask to combine out of the vacuum buffer tank, thereby realizing the purpose of monitoring the vacuum degree in the reaction kettle and the conical flask in real time, simultaneously, the situation that the pipeline is blocked can be prevented by the first PVC hard pipe and the second PVC hard pipe, the problem that the small reaction kettle can not be used by installing the pressure gauge is solved, simultaneously, the materials in the reaction kettle can be prevented from directly entering the vacuum pump by the PVC hard pipe under the negative pressure effect, the blockage and the damage of the vacuum pump are easily caused, and the suck-back can be prevented from occurring after the vacuum pump stops working, avoid the lubricating oil of vacuum pump to get into reation kettle by the PVC hard tube in, pollute the reaction material, destroy the experiment, whole device is rational in infrastructure, the degree of accuracy is high, the practicality is strong.
