Fig. 3 is the cutaway view that the basic structure that is applied to pressure regulator valve of the present invention is shown.
The specific embodiment
To preferred implementation of the present invention at length be described with reference to accompanying drawing now.
Fig. 1 is the structure chart of the basin pipeline in the ship, is used for reducing the equipment of the VOC of ship with explanation, and Fig. 2 is the cutaway view that is applied to injector of the present invention, and Fig. 3 is the cutaway view that the basic structure that is applied to pressure regulator valve of the present invention is shown.
As shown in Figure 1, be ship, especially be under the situation of oil carrier, in order to prevent basin 100 blasts, spray inert gas through IG pipeline (inert gas pipeline), thus the concentration of control oxygen.
In this case, in the present invention, by the method for induction and pressurization gas mixture, making all VOC in the basin 100 all is the VOC that is in the above condensation of saturated vapour pressure, thereby reduces the generation of VOC.
Usually, the widely-used injector that utilizes Venturi effect.
This injector 300 is sent to more than the predetermined altitude perhaps through utilizing the vacuum phenomenon by generation at a high speed to be generally used for discharging swimmingly liquid or the gas that is positioned at the suction side through liquid or the gas with the suction side.
In the present invention, injector 300 is used for the admixture of gas supercharging of inert gas and VOC and is sent to the base portion of basin 100, thus condensation VOC.
For this reason, the present invention includes the pressure regulator valve 400 at the port of export place that is arranged on injector 300.
Pressure regulator valve produces pressure at entrance side, thus pressure is remained on the saturated vapour pressure of liquid goods.For this reason, come the pressure signal of self-controller 500 to control the stroke of pressure regulator valve 400 through the pressure and the reception of measuring leading section.
And the outlet side of pressure regulator valve 400 links to each other with the base portion of basin 100, and therefore, if in the basin 100 inner water-heads that form, then the VOC of evaporation can be by fully condensation by water-head.
Simultaneously, owing to the amount of the liquid goods in the basin 100 can according to circumstances become, therefore, if uneasy dress pressure regulator valve 400, the unsettled liquid goods of then discharging from the outlet of injector 300 possibly produce VOC continuously basin 100.
Yet because the present invention keeps the pressure of the front end of pressure regulator valve 400 equably, therefore, if the liquid goods in the basin 100 is prepared so manyly so that introduce pipeline and discharge pipe can be submerged, VOC can be by fully condensation.
That is, as shown in Figure 2, left side one end that is applied to injector 300 of the present invention links to each other with oil pump, and the other end relative with an end that links to each other with oil pump links to each other with the entrance side of pressure regulator valve 400.
In this case, IG pipeline 200 connects along the radial skew ground of injector 300, thereby separates with an end that links to each other with oil pump but engage with the outermost outlet side.
Thereby; When injector 300 operations, directly forming vacuum by point (that is " A " some place among the figure) top that combines with the oil of discharging at a high speed; Then; Liquid goods of discharging from the introduction pipeline that links to each other with oil pump and the inert gas of under vacuum state, introducing are blended in and are sent to outlet with the mixture of VOC, so can keep sufficiently high pressure, make the pressure of outlet side can remain on the saturated vapour pressure of liquid goods.
Simultaneously; Because the pressure of the outlet side of injector 300 is variable according to the situation (back pressure etc.) of rearward end, therefore, in fact; Only utilize injector 300 to be difficult to pressure is remained on the predetermined pressure; And therefore as stated, pressure regulator valve 400 is installed in part place as shown in Figure 3, so that evenly and continuously keep the pressure of the outlet side of injector 300.
As shown in Figure 3, pressure regulator valve 400 comprises trim portion 430, and this trim portion 430 is installed in leading section 410 places of runner.
In this case, trim portion 430 prevents that unexpected pressure from changing, and when fluid motion, with rearward end 420 places this unexpected pressure possibly take place at leading section 410 and change.When such phenomenon took place, the part of the fluid that separates through the hole of trim portion 430 made it possible to prevent that unexpected pressure from changing.
In other words; Under the situation of common valve; Because cavitation possibly take place at rearward end 420 places for unexpected pressure reduction, and such cavitation is the same with the generation of vacuum and the phenomenon that causes internal flow to evaporate because of vacuum, and therefore final promotion is included in the generation of the VOC in the fluid.
Yet, the invention is characterized in that fluid passes trim portion 430, thereby keep the pressure of leading section 410 equably.
And the dish 440 that links to each other with gear is by driving shaft 450 operations, and the direction that ability longshore current body flows is moved.In this case, regulate pressure like this,, then coil 440 closed front portions 410 if that is: the pressure ratio setting pressure of leading section 440 is low, and if the pressure ratio setting pressure of leading section 410 is high, then coil 440 and open leading section 410.Driving shaft 450 is by the drive source operation such as hydraulic cylinder or motor.
In this case; Pressure regulator valve also comprises pressure measxurement sensor (not shown); This pressure measxurement sensor is installed on the leading section 410 and with controller 500 and links to each other, and is feasible for said controller 500 control panels 440 that keep-up pressure equably, thereby automatically controls the aperture of runner.
As stated; Reduce equipment can keep supplying to basin 100 equably by the pressure regulator valve 400 of the outlet side that is installed in injector 300 pressure according to VOC of the present invention; Make VOC reduce equipment the evaporation of VOC is minimized, that is, the generation of the VOC in the ship is reduced through making the VOC condensation.
