Abstract
The utility model discloses a kind of coal gas drainer of automatic water supplement, including tank body, the tank body is provided with discharge outlet, inserted with gas pipe in tank body, filling pipe is installed at the top of tank body, electric check valve is installed on filling pipe, electric check valve is connected by controller with called putting-into-type liquid level meter, and called putting-into-type liquid level meter is located at tank base；The pressure of liquid is experienced by called putting-into-type liquid level meter to control the off and on of electric check valve.The coal gas drainer of automatic water supplement of the present utility model, real-time current signal is less than setting value, and then valve is opened, real-time current signal is more than or equal to setting value, and then valve is closed, the utility model had both realized timely moisturizing, water seal water shortage, the danger of coal gas breakdown are avoided, the waste of water resource will not be caused again.
Description
Technical field
The coal gas drainer of automatic water supplement is the utility model is related to, belongs to water trap field.
Background technology
During the industry productions such as steel, chemical industry, coal gas drainer performer key player.Its on the one hand row of playing
Water, on the other hand play a part of preventing gas leak, it can normal operation be related to the safety of whole production process.But
The problem of such during use often be present：When gas pressure decline, or the natural evaporation due to water, water seal water level can be low
In drain pipe port height, moisturizing is now needed.If artificial regular moisturizing, mainly by virtue of experience, easily causes water seal water shortage, coal gas is hit
The danger worn；If continuous moisturizing, the waste of water resource can be caused again.So the water supplementing method of existing water trap can not solve
The problems caused by when pressure change and natural evaporation.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, the utility model provides a kind of automatic water supplement
Coal gas drainer, using electric check valve and called putting-into-type liquid level meter, by the switching motion of moisturizing mouth of pipe valve and water seal water level
It is associated, has both realized timely moisturizing, the waste of water resource will not be caused again.
Technical scheme：In order to solve the above technical problems, a kind of coal gas drainer of automatic water supplement of the present utility model, including
Tank body, the tank body are provided with discharge outlet, inserted with gas pipe in tank body, filling pipe are provided with the top of tank body, in moisturizing
Electric check valve is installed, electric check valve is connected by controller with called putting-into-type liquid level meter, and called putting-into-type liquid level meter is located on pipe
Tank base；The pressure of liquid is experienced by called putting-into-type liquid level meter to control the off and on of electric check valve.
The mouth of pipe is diffused preferably, being provided with the top of the tank body.
Preferably, the bottom of the tank body is provided with hand hole.
Preferably, the bottom of the tank body is provided with sewage draining exit.
Beneficial effect：The coal gas drainer of automatic water supplement of the present utility model, real-time current signal are less than setting value then valve
Door is opened, and real-time current signal is more than or equal to setting value, and then valve is closed, and the utility model had both realized timely moisturizing, and avoided water
Water shortage, the danger of coal gas breakdown are sealed, the waste of water resource will not be caused again.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is principle schematic of the present utility model.
Embodiment
As shown in figure 1, the coal gas drainer of automatic water supplement of the present utility model, including tank body 1, the tank body 1 are provided with row
The mouth of a river 7, inserted with gas pipe 2 in tank body 1, filling pipe 3 is installed at the top of tank body 1, is provided with filling pipe 3 electronic
Stop valve 8, electric check valve 8 are connected by controller 9 with called putting-into-type liquid level meter 10, and controller 9 is PLC, throw-in type
The meter of liquid level 10 is located at the bottom of tank body 1, and the top of tank body 1, which is provided with, diffuses the mouth of pipe 4, and the bottom of tank body 1 is provided with hand hole 5 and blowdown
Mouth 6；The pressure of liquid is experienced by called putting-into-type liquid level meter 10 to control the off and on of electric check valve 8.
As shown in Fig. 2 by called putting-into-type liquid level meter 10 when the water trap needs first to set ordinary water level in PLC
The pressure signal transmitted, and it is converted into corresponding current signal (4~20mA).And draining initial time, water seal water level is normal, i.e.,
The mouth of pipe is concordant, and electric check valve 8 is closed, and is flowed into without moisturizing.When gas pressure reduces, or the natural evaporation due to water seal,
Water seal water level decreasing, the pressure signal that now liquid level gauge transmits are converted into after corresponding current signal in PLC with setting
Definite value compares, and is necessarily less than setting value, and PLC sends instruction, and electric check valve 8 is opened, and starts moisturizing.When
Water level rises to original normal level, and the pressure signal that liquid level gauge transmits is converted into after corresponding current signal and setting value ratio
Compared with the two is equal, and PLC sends instruction again, and electric check valve 8 is closed, and stops moisturizing.In brief, i.e., it is electric in real time
Flow signal and be less than setting value then valve opening, real-time current signal is more than or equal to setting value, and then valve is closed.The utility model was both
Timely moisturizing is realized, avoids water seal water shortage, the danger of coal gas breakdown；The waste of water resource will not be caused again.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
