Description

A kind of gas check water seal that can prevent failure
Technical field
A kind of gas check water seal is the utility model is related to, belongs to gas piping equipment technical field.
Background technology
Installation water seal is needed to prevent coal gas from flowing back in gas piping, the gas check water seal used at present there are two water seals Structure, one is to seal gas inlet pipeline, prevents coal gas because when exploding or being tempered, countercurrently returns in gas chamber, another It is to prevent coal gas from leaking using the discrepancy in elevation of water column in overflow pipe and liquid level in water seal.The height of two sealing structure for water is all with coal The fluctuation of atmospheric pressure and change, when gas pressure fluctuation it is larger when, seal gas inlet pipeline sealing structure for water liquid level can under Drop, causes water seal to fail, and causes water seal return-stopping function to fail.Therefore need to solve when gas pressure fluctuation is larger, such as at present What makes the water seal height for sealing gas inlet pipeline keep constant, avoids water seal return-stopping function from failing, while also want overflow pipe not Generation coal gas leaks.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas check water seal that can prevent failure, this Check water seal can make the water seal height for sealing gas inlet pipeline keep constant when gas pressure fluctuates larger, avoid water seal Return-stopping function fails, while also wants overflow pipe that coal gas does not occur and leak.
Solve above-mentioned technical problem technical scheme be:
A kind of gas check water seal that can prevent failure, it includes water seal body, water inlet pipe, gas inlet pipe, coal gas and gone out Mouth pipe, overflow pipe, overflow tube valve, Draw off valve, water inlet pipe and overflow pipe are connected to the upper and lower part of water seal body, coal Gas inlet tube and gas outlet tube are located at the top of water seal fluid chamber, and overflow pipe top is provided with overflow tube valve, overflow pipe Bottom is provided with Draw off valve, and its improvements is that dividing plate is added in water seal fluid chamber, and the lower end of dividing plate is vertically connected on On the bottom surface of water seal fluid chamber, the upper end of dividing plate is higher than the orifice plane of gas inlet pipe, and less than the mouth of pipe of gas outlet tube Water seal fluid chamber is divided into two hydroeciums by plane, dividing plate, and the hydroecium of dividing plate side is relative with gas inlet pipe, and water inlet pipe is with being somebody's turn to do Hydroecium is connected, and the water surface elevation in the hydroecium flushes with the upper end of dividing plate, and the hydroecium of dividing plate opposite side is connected with overflow pipe, Water surface elevation in the hydroecium is less than the upper end of dividing plate.
The above-mentioned gas check water seal that can prevent failure, the position of the overflow tube valve are less than the height of dividing plate, with The water surface elevation for the hydroecium that overflow pipe is connected is less than the height of overflow tube valve.
The beneficial effects of the utility model are:
The utility model sets up one of dividing plate in the inside of water seal chamber, and water seal fluid chamber is divided into two Room by dividing plate, every The water surface in the hydroecium of plate side is closed to gas inlet pipe, and liquid level does not change with gas pressure, so that sealing The water seal height of gas inlet pipeline keeps constant, and the hydroecium of dividing plate opposite side is connected with overflow pipe, and liquid level is with gas pressure Change, does not leak so as to seal coal gas.
The utility model is simple in construction, water seal effect is stable, can keep sealing coal gas when gas pressure fluctuation is larger The water seal height of inlet pipeline is constant, avoids water seal return-stopping function from failing, while overflow pipe can also be kept not occur outside coal gas Let out.The utility model can be promoted the use of in industry, replace existing gas check water seal.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows:Water seal body 1, water inlet pipe 2, gas inlet pipe 3, gas outlet tube 4, overflow pipe 5, overflow pipe valve Door 6, Draw off valve 7, dividing plate 8, water seal height h, overflow height H.
Embodiment
The utility model is by water seal body 1, water inlet pipe 2, gas inlet pipe 3, gas outlet tube 4, overflow pipe 5, overflow pipe valve Door 6, Draw off valve 7, dividing plate 8 form.
Shown in figure, water inlet pipe 2 and overflow pipe 5 are connected to the upper and lower part of water seal body 1, the He of gas inlet pipe 3 Gas outlet tube 4 is located at the top of the chamber of water seal body 1, and the top of overflow pipe 5 is provided with overflow tube valve 6, the bottom peace of overflow pipe 5 Equipped with Draw off valve 7, these structures use prior art.
Shown in figure, the utility model adds dividing plate 8 in the chamber of water seal body 1, and the lower end of dividing plate 8 is vertically connected on water To seal on the bottom surface of the chamber of body 1, the upper end of dividing plate 8 is higher than the orifice plane of gas inlet pipe 3, and less than the pipe of gas outlet tube 4 The chamber of water seal body 1 is divided into two hydroeciums by mouth plane, dividing plate 8.
Shown in figure, relative with gas inlet pipe 3 by the hydroecium that dividing plate 8 separates, water inlet pipe 2 is connected with the hydroecium Connect, the water surface elevation in the hydroecium flushes with the upper end of dividing plate 8.Because the upper end of dividing plate 8 is put down higher than the mouth of pipe of gas inlet pipe 3 Face, therefore the water surface of the hydroecium is closed to gas inlet pipe 3.
Shown in figure, another hydroecium separated by dividing plate 8 is connected with overflow pipe 5, and the position of overflow tube valve 6 is less than The height of dividing plate 8, therefore, the water surface elevation for the hydroecium being connected with overflow pipe 5 are not only less than the height of dividing plate 8, while also low In the height of overflow tube valve 6.
The course of work of the present utility model is as follows:
The utility model adds dividing plate 8 in the chamber of water seal body 1, and the upper end of dividing plate 8 is higher than the mouth of pipe of gas inlet pipe 3 Plane, and the chamber of water seal body 1 is divided into two hydroeciums, two hydroeciums point less than the orifice plane of gas outlet tube 4, dividing plate 8 Water seal and overflow are not played a part of.
During normal work, overflow tube valve 6 is opened in the water filling of water seal body 1, and the gas pressure in water seal body 1 relies on overflow pipe 5 Interior fluid column overflow height H is sealed, and ensures that coal gas does not leak.Water seal height h in the hydroecium relative with gas inlet pipe 3 Gas inlet pipe 3 seals, to reach the purpose of check coal gas.
When gas pressure fluctuates, the height of the fluid column overflow height H in overflow pipe 5 can change, and can keep overflow pipe 5 Coal gas does not occur to leak, but the water surface liquid level in the hydroecium relative with gas inlet pipe 3 will not change, so that The water seal height h for sealing gas inlet pipeline 3 keeps constant, reaches the purpose for avoiding water seal return-stopping function from failing.
