The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, the urgent freeing arrangement of the utility model dish fuel bowl mainly is made up of water seal tube 1, connecting panel 2, guide shell 3, dish-shaped float 4, valve seat 6, seal ring 7, automatic water replenishing device 8, catchment filter 9, tie bolt 10, peep hole 11, tie bolt 12 etc.Water seal tube 1 links to each other with guide shell 3 by connecting panel 2, dish float 4 freely is placed in the guide shell 3, guide shell 3 is installed on the valve seat 6 by tie bolt 5, seal ring 7 is installed in the circular groove of valve seat 6, automatic water replenishing device 8 is installed on the valve seat 6 by screw thread, catchment filter 9 is installed on the valve seat 6 by bolt 10, and peep hole 11 is fixedly connected on the centre of catchment filter 9, and urgent freeing arrangement totally is installed on the floating apical grafting pipe flange by bolt 12.
Shown in Fig. 2,3 (front view and birds-eye view), water seal tube 1 is made up of cylindrical shell and connecting panel 2, and connecting panel 2 is fixedly connected on the cylindrical shell; The effect of water seal tube is a water storage, forms water seal.Connecting panel is a fitting fastening.
Shown in Fig. 4,5 (front view and birds-eye view), guide shell 3 is made up of cylindrical shell, flange, connecting panel 2 and damping baffle plate; Flange is welded on cylindrical shell one end, and connecting panel 2 is welded on cylindrical shell and the flange, and the damping baffle plate is welded on cylindrical shell one end inboard.The effect of guide shell is to make aqueous fluid by directed flow.Connecting panel is a fitting fastening.
Shown in Fig. 6,7 (front view and birds-eye view), dish-shaped float 4 outer shape are dish-shaped shell, and curved surface is sphere or elliptical area.
Shown in Fig. 8,9 (front view and birds-eye view), valve seat 6 is disc flanges of a band groove, is the parts that connect guide shell 3, installation seal ring 7, automatic water replenishing device 8, catchment filter 9 and link to each other with the pipe connecting flange on floating top by bolt (12).
Shown in Figure 10,11 (front view and birds-eye view), seal ring 7 is annular arrangements, and annulus one side is straight mouthful, and opposite side is tubaeform mouthful.Its effect is to form face contact seal with the sphere curved surface of dish-shaped float.
Shown in Figure 12,13 (front view and birds-eye view), catchment filter 9 is that a top has concave surface, border and bottom to have filter opening, inboard that the short cylindrical shape housing of support is arranged, and it act as and filters and collect rainwater.Easy to operate in order to use, handle is installed on concave surface.
This device is installed on the floating outward top of oil tank, has following function:
1. urgent draining: when floating top upper surface because of various reasons and ponding, and water accumulating volume is when surpassing design height, the ponding that overloads promptly can flow to catchment filter.By catchment filter, flow into guide shell.Technological core of the present utility model is to have adopted dish-shaped float, and its profile is dish.The dish float has the characteristic that is the existence of minimum drag state under the effect of current, thereby the section on fluid passage section is little, resistance is little, flow is big, too much jeopardize its normal operation in emergency circumstances at floating top ponding, can promptly overload ponding be entered the water seal tube, enter in the jar by the water seal tube again, thereby can avoid floating top too much to cause the generation of sinking accident because of ponding.
2. prevent that liquid storage from fall overflowing: when because of various reasons, when liquid storage will take place down to overflow, the water seal liquid level in the guide shell rose, the float rise, under buoyancy function, and contact and compress with seal ring, buoyancy is big more, sealing load is big more, and sealing effectiveness is good more, thereby can prevent effectively that falling of liquid storage is excessive.
3. water seal oil gas: usually, fills with water in the water seal tube, water separates oil and air, thereby prevents the volatilization of lightweight oil content, has realized the function of water oil sealing gas.
The utility model uses as urgent freeing arrangement, when floating top upper surface because of various reasons and ponding, and water accumulating volume is when surpassing design height, the ponding that overloads promptly can flow to catchment filter.By catchment filter, flow into guide shell.The dish float is the minimum drag state and exists under the effect of current, drain discharge is big, too much jeopardize its normal operation in emergency circumstances at floating top ponding, can promptly overload ponding be entered the water seal tube, enter in the jar by the water seal tube again, thereby can avoid floating top too much to cause the generation of sinking accident because of ponding.When because of various reasons, when liquid storage will take place down to overflow, the water seal liquid level in the guide shell rose, and float rises, under buoyancy function, and contact and compress with seal ring, buoyancy is big more, sealing load is big more, and sealing effectiveness is good more, thereby can prevent effectively that falling of liquid storage is excessive.Usually, fills with water in the water sealed tank, water separates oil and air, thereby prevents the volatilization of lightweight oil content, has realized the function of water oil sealing gas.
Adopt dish-shaped float, resistance of water drainage is little, and displacement is big, and urgent drainage performance is good, and oppositely sealing is tight, can prevent dehydration moisturizing voluntarily again than actv., has reduced the hand labor amount, has made things convenient for management, can reduce the sewage generation again; Adopt novel oil separation structure, solved because of coagulating oil and stopped up the problem that causes urgent draining to lose efficacy.
On floating top, install to change and be welded as bolted connection, in service at oil tank, also detachable, come into operation in case solved urgent freeing arrangement oil tank in the past, just the problem that can't overhaul.
