Embodiment
As shown in Figure 1 and Figure 2, the utility model coal gas is regulated hydathode automatically and is included a shell of tank that has import 1 and an outlet 8, and the water outlet of this import and original coal gas drainer 100 is connected; By a dividing plate 5 it is divided into upper and lower room, the valve opening mutual conduction of upper and lower room in the container by offering on the dividing plate.
Described valve opening below connects a valve seat 3, and an outer angle point of valve seat bottom is connected with its hydraulic equilibrium device as pivot point; The hydraulic equilibrium device of the utility model one embodiment design is constituted with lower valve plate 11 by hollow float 9 on, both intersection points are fixed on the outer angle point place of valve seat bottom by hinge support 10, wherein, the weight of hydraulic equilibrium device (promptly referring to hollow float 9) should be greater than the weight of valve plate; The lower valve plate of this hydraulic equilibrium device is simultaneously as the baffle plate that opens and closes the valve seat valve.
The conjuncted ball float snubber 6 that is provided with above valve opening, the ball float snubber of the utility model one embodiment design is big, a following young frustum formula annular wall suitable for reading, one ball float 7 is suspended in the ball float snubber, the distance of the upper end of ball float snubber and shell of tank top end cover is less than the diameter of ball float, to guarantee that ball float can be from emersion in the ball float snubber.
An one annular overflow weir 2 and an annular are set in lower chamber simultaneously bury weir 4, this annular overflow weir rises sheer from the bottom, is adjacent to suction side; Annular is buried the weir reverse graft in dividing plate (being connected with dividing plate below), is positioned at the inboard of annular overflow weir, annular overflow weir and annular is set simultaneously buries the weir and promptly formed N type condensation water seal path, has effectively increased the draining sensitivity of coal gas wave protection dead band generation.
The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection domain that the utility model is applied for a patent.
Coal gas of the present utility model is regulated the hydathode working procedure automatically: enter the import 1 that coal gas is regulated hydathode automatically when the condensed water of coal gas drainer is discharged, flow through annular overflow weir 2, bury weir 4 arrival coal gas through annular then and regulate the hydathode internal tank automatically, rise to water level, the water level that rises makes hollow float 9 be subjected to the buoyancy rising, and the valve plate 11 that is connected with hollow float 9 is subjected to force direction change decline unlatching valve plate 11 after by hinge support 10, open valve seat 3, water level continues to rise, pass the ball float snubber 6 on the dividing plate 5, make ball float 7 come-ups, condensed water overflows, discharge from exporting 8, realize the normal function of discharging of condensed water in the gaspipe line, referring to Fig. 2.
When the gaspipe line gas pressure fluctuates within the specific limits, the condensate water level that the water level of the coal gas drainer that is attached thereto, coal gas are regulated in the hydathode automatically also produces fluctuation within the specific limits, because it is to be inserted in the annular overflow weir 2 that is full of condensed water that the annular that coal gas is regulated hydathode is automatically buried weir 4, so, open or closed condition even the variation up and down within the specific limits of this water level is with ball float snubber 6 and valve plate 11, realized that just coal gas regulates the function of hydathode Sensitivity range automatically.
If gas pressure continues to increase; surpass the sensitivity protection domain; cause condensed water to be extruded by gas pressure; and coal gas is regulated the hydathode water level automatically and is descended significantly; descend behind ball float snubber 6 loss of buoyance; the valve plate 11 that is attached thereto rises and closes valve seat 3, realizes preventing the function of gas leakage, referring to Fig. 3.
When the coal gas in the gaspipe line does not have condensed water to discharge, the condensed water of ball float snubber 6 because of with atmosphere in, so be easier to evaporate.But, along with the condensation evaporation of water, drawdown, ball float 7 also descends along with the decline of water level simultaneously, and when dropping to the lowest water level of 6 li of ball float snubbers, ball float 7 separates condensed water and atmosphere, has avoided evaporation, has realized the function of water saving, referring to Fig. 4.
The utility model coal gas is regulated hydathode automatically and has been designed water seal breakdown protection device, when the gas pipe line gas pressure surpasses the Safety water seal pressure of water seal, gas pressure with the hydraulic pressure of water tight compartment outside water seal, make the drawdown of water tight compartment, because of the hydraulic equilibrium device nt wt net weight of valve plate descends greater than valve plate, so, by supporting hinges valve plate is risen, close outlet, cut off coal gas, can play the effect of protection coal gas system safety in production; Coal gas is regulated hydathode automatically and has been designed annular and bury weir formula sensitivity regulator, has solved the dead-time problem of the general coal gas draining of piped gas pressure surge protector effectively.When piped gas pressure surge during in certain limit, general coal gas drainer is as long as surpass water seal pressure, piped gas is discharged at once, this multi-functional water seal protective gear at piped gas pressure when certain limit fluctuates, the gas pressure of fluctuation at first makes annular bury the water appearance fluctuation that weir formula sensitivity regulator buries the both sides, weir, the height that this imbeds the weir has determined the height of water seal water level, the Sensitivity range that has also determined to bury weir formula sensitivity regulator simultaneously; The float-ball type partition apparatus that coal gas is regulated hydathode design automatically effectively plays the effect of vaporization prevention.
