Embodiment
The utility model realizes that the coal gas drainer of pressure taking method can be to be composed in series by N horizontal connecting vessels, have the water that is used for shutoff coal gas in the water tight compartment of each connecting vessels, one water sealing (sealing water) pipe is uprightly arranged in each water tight compartment, each water sealing (sealing water) pipe lower end suspension opening, the upper end-hole of each water sealing (sealing water) pipe from the second level to the afterbody connecting vessels water tight compartment and the water tight compartment of previous stage connect; First order connecting vessels upper end-hole is offered the outlet that communicates with atmosphere as the import that receives gas pressure on the afterbody connecting vessels.
But this coal gas drainer is as shown in Figure 1 and Figure 2 embodiment's form also, adopts and integrates one, promptly includes airtight hydathode shell 1, side at airtight hydathode shell 1 has import 6, be used for and coal gas UNICOM, opposite side has outlet 9, is used for communicating with atmosphere.Water sealing (sealing water) pipe 2, dividing plate 3 are arranged in airtight hydathode shell 1 and be used for the water 4 of shutoff coal gas, also have PRESSURE TAP 5, can regulate PRESSURE TAP 7, can regulate PRESSURE TAP 8.
The structural type of described pressure adjutage 7 can have a pressure tube socket 704 as shown in Figure 3, and the external thread bolt connection of adjutage 705 by pressure tube socket 704 is on the water tight compartment room roof of correspondence.Adjutage 705 is a hollow tube, and the lower end is inserted in the interior water of water tight compartment, and upper end-hole is stamped nut 701.Be to realize sealing, can block up the sealing of 704 of realization pressure adjutage 705 and pressure tube sockets by the pressure of stuffing box packing 703 with a nut 702.During work, unclamp nut 702, by adjusting the adjusting that adjutage 705 lower ends are inserted into the liquid level height realization pressure value in the airtight hydathode.
The utility model coal gas drainer routine work state (as shown in Figure 1) is: gas pressure enters from a side-entrance 6 of airtight hydathode shell 1, gas pressure acts on the liquid level of water tight compartment 4 of shutoff coal gas, coal gas is by three water column shutoff that formed by water sealing (sealing water) pipe 2,201,202, makes the coal gas can not be excessive.Under the pressure state (as shown in Figure 2), after then pressure value was as required calculated in advance, the height in the pressure adjutage insertion liquid level set in which water tight compartment was regulated in decision, after this pressure adjutage is transferred to predetermined height, open nut 701, can obtain the pressure Vo that desires to get.
The coal gas drainer that is three water tight compartments of 1000mm with a water sealing (sealing water) pipe height L is that example (N=3) specifies pressure taking method of the present utility model as shown in Figure 1 and Figure 2, below.It is equivalent to the water seal water column of the integral body that 3 connecting vesselss that separate with dividing plate 3 are connected into, show among Fig. 1 and have three water sealing (sealing water) pipes, total effective length of these three water sealing (sealing water) pipes 2,201,202 is 3000mm, be the water seal total height, can shutoff 30kPa(that is Vmax=30kPa) gas pressure.Pressure principle according to vertical water column, import 6 places are equivalent to the bottom of this whole vertical water column, after gas pressure enters coal gas drainer from import 6, gas pressure acts on the pressure that forms on the liquid level of water 4 of shutoff coal gas, three water tight compartments from import 6 to outlet 9 reduce step by step, because being three water columns by three water sealing (sealing water) pipes 2,201,202 of three water tight compartments, the coal gas drainer in the example is in series, so the pressure that records from these three water columns respectively reduces by 1/3rd from import 6 to outlet 9.In concrete pressure is used, as the pressure of need 30kPa, can be from PRESSURE TAP 5 direct pressures, the pressure that this place gets is equivalent to the base pressure at 3000mm height water column, that is that get originally is the available maximum pressure value Vmax of equipment.As the pressure of need 20kPa, can be from the 7 direct pressures of can regulate PRESSURE TAP, the pressure that this place gets is equivalent to the pressure of the water column of 3000mm height at the 2000mm place; As the pressure of need 10kPa, can be from the 8 direct pressures of can regulate PRESSURE TAP, the pressure that this place gets is equivalent at the pressure of 3000mm height water column at the 1000mm place; As need 15kPa pressure, PRESSURE TAP 7 places can regulated, unclamp nut 702, by after adjusting adjutage 705 lower ends and being inserted into liquid level 500mm place (as shown in Figure 2) in the airtight hydathode shell 1, gland nut 702, the pressure that this place gets are equivalent to the pressure at the 1500mm place of 3000mm height water column; By that analogy, can in the pressure range of hydathode water seal, get the needed pressure of Pneumatic actuator arbitrarily by above-mentioned pressure taking method.From top giving an example yet as can be seen, when value Vo is 30kPa, 20kPa and 10kPa, need not adjust the height of regulating in the pressure pipe insertion liquid; When other pressure values of needs, calculate in advance and confirm to regulate adjusting pressure pipe in which water tight compartment, obtain the pressure got from this adjusting pressure pipe suitable for reading, use for other equipment or project.
According to the behaviour in service of common equipment, preferred embodiment of the present utility model is: the number N of water tight compartment is made as 2 ~ 8 and is advisable; Effective active length L of water sealing (sealing water) pipe is that 1000mm is suitable.
The foregoing description 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.
