The working process of the invention is explained below with reference to the drawings.
First, the storage tank contains water, and the working condition is normal when the water is cut off
When water in the storage tank enters the upper cavity, the floating ball 2 and the floating rod connecting shaft 3 are subjected to the buoyancy action of the water as a whole.
The liquid level of the water submerges the upper opening of the water guide channel 5, the water reaches the bottom bin through the upper end wire mesh 4, and the partition plate 12 is subjected to the buoyancy of the water (the buoyancy of the object is due to the pressure difference on the upper surface and the lower surface of the object, and the partition plate is only subjected to the pressure on the upper surface and the buoyancy of the floating ball at the moment and does not have the buoyancy on the lower surface before the water enters the bottom bin because the lower part of the object is not contacted with. An observation floating ball 6 in the water guide channel 5 is used for indicating the liquid level height of the filled water.
The floating ball 2, the floating rod connecting shaft 3 and the partition plate 12 are subjected to the buoyancy action of water, and when the water level reaches the height of the floating ball 1/2, the buoyancy force applied to the floating ball, the floating rod connecting shaft and the partition plate is equal to the gravity; when the water level exceeds the height of the floating ball 1/2, the floating ball, the floating rod connecting shaft and the partition plate integrally start to rise, water starts to be discharged through the water outlet 10, and the partition screen 8 prevents the floating amount of the partition plate 12 from exceeding the limit and falling back to the initial state (if the partition screen 8 is not arranged, the partition plate may shake in disorder, and finally, the partition plate does not return to the normal position when falling back).
When the water begins to gradually decrease to 1/2 below the height of the floating ball along with the discharge of the water, the floating ball, the floating rod connecting shaft and the clapboard begin to fall under the influence of gravity and seal the water outlet 10, the water cutting work is finished, and a water seal is formed in the chamber.
When water in the valve body needs to be discharged, the valve is opened through the emptying valve 13 to discharge water, along with the reduction of the water level, oil begins to enter the water guide channel 5, the density of the floating ball 6 is observed to be smaller than that of water and larger than that of oil, the floating ball 6 begins to reduce along with the reduction of the water level, an oil-water boundary is indicated, and oil discharge is prevented. Secondly, the storage tank is not filled with water, and the working condition is that the storage tank is empty of water
The oil enters the upper cavity, the oil reaches the bottom bin through the upper end screen 4, at the moment, the water in the storage tank can be judged to be not water by observing the non-floating state of the floating ball 6, and the water cutting can be stopped (the water cannot be discharged sometimes in the field, the water is not known to be in the bottom, or the outlet valve of the storage tank is blocked, the judgment is not easy.
And after the upper chamber and the lower chamber are filled with oil, water is cut again. Along with the entering of water, the oil in the bottom storehouse is opened progressively to water (water is walked down, oil is up floating, this application drain valve passes through the pipeline and is being connected the storage tank, is equivalent to oil and has traded a position with water, oil has returned the storage tank, and water advances the drain valve), observes floater 6 and begins the come-up, along with the come-up of oil, and water is in the rising of upper chamber liquid level, begins normal water cutting work after reaching the floater 1/2 height.
Third, prevent frostbite in winter
The valve body is heated by the heat tracing pipe 9, so that oil with high freezing point and residual water are prevented from being frozen. The heat tracing pipe 9 is only arranged on one side of the cavity, the valve body is not large in size, the heat tracing temperature on one side can meet the use requirement, and the valve is compact in structure and small in size.
When freezing occurs, manual treatment can be performed through the water outlet 10 (hot water or steam can be poured inwards through the water outlet 10 to slowly thaw the outlet, the partition plate is pried upwards by a tool from below, and a pipe is extended to introduce a heat medium).
Fourthly, density adjustment
The balancing weight 11 is used for adjusting the overall weight of the floating ball 2, the floating rod connecting shaft 3 and the partition plate 12 and adjusting the overall weight according to the density of different oil products in the storage tank.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the invention.
