Abstract

The utility model discloses a drainer without air consumption. The drainer comprises an air cavity and a drainage pipe, wherein the air cavity is provided with an air inlet and an air outlet, and the drainage pipe is communicated with the air cavity. The drainer further comprises a liquid level detection pipe, a controller, a valve body and a valve driver for driving the valve body to work, wherein the liquid level detection pipe is arranged in the air cavity and provided with a high liquid level detection unit and a low liquid level detection unit. Signals of the high liquid level detection unit and the low liquid level detection unit are input to the controller which is in output connection with the valve driver, and the valve body is arranged on the drainage pipe. When the drainer without air consumption is used, the controller controls the valve body to be opened when water in the air cavity is accumulated to a high liquid level, and the water in the air cavity can be drained from the drainage pipe. When the water in the air cavity descends to a low liquid level, the controller controls the valve body to be closed. Therefore, in the whole process of air exhaust, the water in the air cavity always keeps a certain water level, compressed air above the water surface can not be exhausted through the drainage pipe, and water drainage without air consumption can be achieved.

Description

No gas consumption hydathode

Technical field

The utility model relates to a kind of hydathode, especially a kind of no gas consumption hydathode.

Background technique

Compressed air is very extensive industrial application; And compressed air accumulates more moisture content easily in generation, running; Make troubles for the gas user; As: when with the air water entrainment in gas instrument or the equipment; Water can wash out the lubricating oil in these equipment; Thereby cause engine and bearing excessive loss, finally increase maintenance cost, going slick property of some instruments (especially pneumatic hammer, drilling machine, crane and percussion hammer) and efficient can greatly reduce;

In addition, spray paint, glazing, food stirring and other with gas technology in, water does not allow to exist;

In instrument usefulness gas system, water does not allow to exist yet, and reason is that the water capacity is prone to be attached on the valve nozzle, and gathers dirt, causes the fluctuation of service or the fault of sensor;

And for example in the field of pressurized air as transmitting power; When water when the pipeline lower is assembled, can reduce pipeline transmission capacity, and when water enters into equipment with very high speed; Can cause many potential hazards; As equipment being produced bigger impact, when perhaps weather was colder, the water that gathers can freeze and with frost crack pipe.

Therefore hydathode need be set on compressed air line drains airborne water; The problem that existing hydathode exists is: in drainage procedure; The pressurized air of a part can be drained along with water together; Therefore thereby cause the increase of gas consumption, cause the wasting of resources, be necessary to invent a kind of no gas consumption hydathode that pressurized air can not drained along with water together in drainage procedure.

Summary of the invention

The purpose of the utility model is a kind of no gas consumption hydathode that pressurized air can not drained along with water together in drainage procedure that designs for the deficiency that solves above-mentioned technology.

The no gas consumption hydathode that the utility model designed; Comprise air cavity and waste pipe; Said air cavity is provided with suction port and air outlet; Said waste pipe is communicated with air cavity, also comprises the valve actuator of Level Detection pipe, controller, valve body and actuating valve body running, and said Level Detection pipe is arranged in the air cavity and on this Level Detection pipe, is provided with high Level Detection unit and low Level Detection unit; Said high Level Detection unit and low Level Detection cell signal input to said controller, and this controller output connects said valve actuator, and said valve body is arranged on the waste pipe.

As preferably: said waste pipe stretch into said air cavity and dip section downward-sloping, like this, the impurity in the pressurized air is difficult for stopping up waste pipe.

As preferably: said high Level Detection unit and low Level Detection unit are liquid-level switches, can certainly be other liquid level detection devices.

The no gas consumption hydathode that the utility model designed; When the water in the air cavity was accumulated to high liquid level, the controller control valve body was opened, and the water in the air cavity just can be discharged from waste pipe; And liquid level descends thereupon; When reducing under water in the air cavity hanged down liquid level, the controller control valve body was closed, and the water in the air cavity just can not be discharged from waste pipe at this moment; Therefore in the process of whole exhaust; Remaining certain water level in the air cavity; The pressurized air that is arranged in water surface top just can not be discharged from waste pipe, and therefore, the no gas consumption hydathode that the utility model designed can realize that draining do not have gas consumption; More effectively economize on resources, this no gas consumption hydathode can be applied in each pressurized air application widely.

Among the figure: air cavity 1, waste pipe 2, Level Detection pipe 3, controller 4, valve body 5, valve actuator 6, high Level Detection unit 7, low Level Detection unit 8.

Embodiment

Combine accompanying drawing that the utility model is done further to describe through embodiment below.

Embodiment 1:

As shown in Figure 1; The described no gas consumption hydathode of present embodiment; Comprise air cavity 1 and waste pipe 2, said air cavity 1 is provided with suction port and air outlet, and said waste pipe 2 is communicated with air cavity 1; Also comprise Level Detection pipe 3, controller 4, valve body 5 and drive the valve actuator 6 that valve body 5 is worked, said Level Detection pipe 3 is arranged in the air cavity 1 and on this Level Detection pipe 3, is provided with high Level Detection unit 7 and low Level Detection unit 8; Said high Level Detection unit 7 inputs to said controller 4 with low Level Detection unit 8 signals, and these controller 4 outputs connect said valve actuator 6, and said valve body 5 is arranged on the waste pipe 2.Said waste pipe 2 stretch into said air cavity 1 and dip section downward-sloping, like this, the impurity in the pressurized air be difficult for to stop up waste pipe 2.Wherein, said high Level Detection unit 7 is liquid-level switches with low Level Detection unit 8, can certainly be other liquid level detection device.

The described no gas consumption hydathode of present embodiment; When the water in the air cavity 1 was accumulated to high liquid level, controller 4 control valve bodies 5 were opened, and the water in the air cavity 1 just can be discharged from waste pipe 2; And liquid level descends thereupon; When reducing under water in the air cavity 1 hanged down liquid level, controller 4 control valve bodies 5 were closed, and the water in the air cavity 1 just can not be discharged from waste pipe 2 at this moment; Therefore in the process of whole exhaust; Remaining certain water level in the air cavity 1, the pressurized air that is arranged in water surface top just can not be discharged from waste pipe 2, therefore; The described no gas consumption hydathode of present embodiment; Can realize that draining do not have gas consumption, more effectively economize on resources that this no gas consumption hydathode can be applied in each pressurized air application widely.
