Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the gas-liquid water seal warning water replenishing device that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, the utility model embodiment provides a kind of gas-liquid water seal warning water replenishing device, comprises U-shaped pipe 10, arm 11, mortor operated valve 1, high water level liquid-level switch 2, low water level liquid-level switch 3, Blowoff ball valve 4 and a plurality of ball valve.The upper end in the left side of U-shaped pipe 10 is connected to gaspipe network, and the upper end on the right side of U-shaped pipe 10 connects one by ball valve 8 and collects pond (illustrating, not label), and the left side of U-shaped pipe 10 is connected by a ball valve 7 with right side.Mortor operated valve 1 is installed on arm 11, arm 11 is connected in the right side of U-shaped pipe 10, high water level liquid-level switch 2 and low water level liquid-level switch 3 are installed on the left side of U-shaped pipe 10, and high water level liquid-level switch 2 is positioned at the top of low water level liquid-level switch 3, mortor operated valve 1 arranges with high water level liquid-level switch 2 and low water level liquid-level switch 3 interlockings simultaneously, high water level liquid-level switch 2 is connected with a warning device (not shown) respectively with low water level liquid-level switch 3, for the use of reporting to the police.Blowoff ball valve is installed on the bottom of U-shaped pipe 10, and is connected to sewage collection equipment (illustrating, not label).And the both sides of U-shaped pipe 10 lower ends are respectively equipped with ball valve 5,6, wherein the ball valve 5 in left side is positioned at the below of low water level liquid-level switch 3, and the ball valve 6 on right side is positioned at the below of the tie point of arm 11 and U-shaped pipe 10.
As Fig. 1, when this gas-liquid water seal warning water replenishing device is normally worked, mortor operated valve 1, Blowoff ball valve 4 and ball valve 7 are all in normally off; Ball valve 5, ball valve 6 and ball valve 8 are all in normally open.Due to the metastable effect of the interior gas pressure of U-shaped pipe 10, the water in the left side of U-shaped pipe 10 can form liquid level stabilizing in blast furnace low water level, lower than certain region of high water level liquid-level switch 2; The general interior coal gas of U-shaped pipe 10 can produce pressure surge among a small circle, and liquid level moves up and down with pressure, all scope is reasonably being set; Once normal, produce and be in an emergency or accident, gas pressure sharply raises, and liquid level can decline suddenly, and the water in U line pipe is understood some and is forced out pipeline, enters and collects pond, and coal gas, through U-shaped pipe 10 bottoms, walks to right side and overflows.In order to prevent such situation, when liquid level drops to low water level, while being detected by low water level liquid-level switch 3, can start warning device, thus automatic alarm, and open mortor operated valve 1, to the right side water filling of U-shaped pipe 10, the liquid level in compressing left side rises, and prevents that coal gas from puncturing U-shaped pipe 10.When liquid level is elevated to high water level, while being detected by high water level liquid-level switch 2, then close mortor operated valve 1, moisturizing finishes.
As Fig. 1, when forming, U-shaped pipe 10 bottoms stop up, in the time of need to rinsing, ball valve 6 and ball valve 8 are closed, open Blowoff ball valve 4, mortor operated valve 1, constantly rinses, until rinse well; Then, first close Blowoff ball valve 4, then time-delay closing mortor operated valve 1, then open ball valve 6 and ball valve 8, recover normally to work.When U-shaped pipe 10 bottoms, stop up, be badly in need of again safeguarding and produce, can open ball valve 7, close ball valve 5 and ball valve 6, form new water seal, maintain in short-term and produce.
As Fig. 1, gas-liquid water seal warning water replenishing device of the present utility model is provided with high water level liquid-level switch 2 and low water level liquid-level switch 3 by the left side at U-shaped pipe 10, can monitor the lifting of U-shaped pipe 10 interior liquid levels; And its right side is provided with the arm 11 of wearing mortor operated valve 1, for moisturizing, and mortor operated valve 1 arranges with high water level liquid-level switch 2 and low water level liquid-level switch 3 interlockings simultaneously, can realize timely moisturizing, prevent that gas pressure from raising, from U-shaped pipe 10 bottoms, puncture, overflow pipeline, use safer reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
