As shown in Figure 1 and Figure 2, split type drainage mechanism of the present invention also comprises the second piston 5, second piston loading spring 6; Second piston 5 can in the axial direction on guide rod 2 sealing slide, bottom this second piston 5, periphery wall is provided with large sealing packing ring 5-1, and this second piston 5 is at the bottom of first piston 3 and case between 1-2.Second piston 5 comprises upper piston area and piston base equally, and upper piston area is the cylindrical structural of hollow and is sheathed on the periphery wall of guide rod 2, piston in the axial direction on guide rod 2 sealing slide; Second piston loading spring 6 is installed around described guide rod 2, is tending towards moving up to drive the second piston 5 for applying elastic force to the second piston 5.
As shown in Figure 1 and Figure 2, be provided with the embedded sleeve pipe 7 that can slide up and down along the axial component of the second piston 5 between 1-2 at the bottom of the second piston 5 and case, bottom embedded sleeve pipe 7, periphery wall can be provided with small sealing ring 7-1.Form annular outer seal chamber 5-3 between 1-2 at the bottom of embedded sleeve pipe 7, second piston 5 and case, this annular seal space 5-3 by embedded sleeve pipe 7 mobile realize with delivery port be communicated with or closed.First piston 3 is provided with the first functional element 3-2, and embedded sleeve pipe 7 is provided with the interactional second functional element 7-2 with the first functional element 3-2, and the interaction of the first functional element 3-2 and the second functional element 7-2 is to realize the movement of embedded sleeve pipe 7.Can be provided with between embedded sleeve pipe 7 and the second piston 5 makes embedded sleeve pipe 7 be tending towards the back-moving spring 7-3 moved down.Embedded sleeve pipe 7 is provided with small sealing ring 7-1, and small sealing ring 7-1 moves with embedded sleeve pipe 7 and for 1-2 at the bottom of stuffing box.In the present embodiment, element is the magnetic element that magnetic material is made one of in first functional element 3-2 and the second functional element 7-2, another part is the magnetic element that magnetic material is made or the hardware be made up of metal material, and the first functional element 3-2 and the second functional element 7-2 attracts each other.
Water inlet and the drainage procedure of split type drainage mechanism of the present invention are described below in conjunction with accompanying drawing 1-5.
Fig. 1, Fig. 2 show split type drainage mechanism original state.Now first piston 3 is positioned at 1-2 at the bottom of case (lower position-arresting is put), and first piston 3 extrudes the second piston 5 and makes the second piston 5 also be positioned at its lower position-arresting to put, and at the bottom of the large sealing packing ring 5-1 on the second piston 5 and case, 1-2 seals.Embedded sleeve pipe 7 is at the bottom of the second piston 5 and case between 1-2, embedded sleeve pipe 7 interacts by the first functional element 3-2 and the second functional element 7-2 and is in upper position-arresting and puts, now, embedded sleeve pipe 7 and the unrealized sealing of 1-2 at the bottom of case, annular outer seal chamber 5-3 is communicated with delivery port.
Fig. 3 shows split type drainage mechanism water inlet state.Open gauge tap (not shown), current enter lower chambers 1-4, and hydraulic pressure overcomes the elastic force of first piston loading spring 4 and up promoted by first piston 3.Under hydraulic pressure effect, the second piston 5 stays on and to put at lower position-arresting, and the large sealing packing ring 5-1 on the second piston 5 continues to seal with 1-2 at the bottom of case.Mutual magneticaction between first functional element 3-2 and the second functional element 7-2 reduces due to the increase of relative distance, and embedded sleeve pipe 7 moves down due to self gravitation and spring force effect, and embedded sleeve pipe 7 also realizes sealing state with 1-2 at the bottom of case.
First piston 3 is up in moving process, mutual magneticaction between first functional element 3-2 and the second functional element 7-2 reduces, back-moving spring 7-3 starts to reset, and reseting elasticity also makes embedded sleeve pipe 7 move down, at the bottom of small sealing ring 7-1 on embedded sleeve pipe 7 and case, 1-2 seals, thus annular outer seal chamber 5-3 and delivery port are sealed.In addition, as being provided with small sealing ring 7-1 on embedded sleeve pipe 7, then small sealing ring 7-1 strengthens the sealing with 1-2 at the bottom of case.
Fig. 4, Fig. 5 show split type drainage mechanism hull-borne.When gauge tap control casing 1 carries out draining, press water enters annular seal space 5-3, and the second piston 3 and embedded sleeve pipe 7 jack-up move up by water pressure and the second piston loading spring 6 elastic force.Meanwhile, because the water yield of lower chambers 1-4 reduces gradually, first piston 3 down promotes by the elastic force of first piston loading spring 4.Finally, first piston 3 and the second piston 5 close.Because the mutual attractive force between the first functional element 3-2 and the second functional element 7-2 increases, thus relative second piston 5 of embedded sleeve pipe 7 is moved up.Therefore, when at the bottom of the large sealing packing ring 5-1 and case of the second piston 5,1-2 realizes sealing, embedded sleeve pipe 7 (or the small sealing ring 7-1 on embedded sleeve pipe 7) also does not realize sealing with 1-2 at the bottom of case, the water of annular outer seal chamber 5-3 then can flow out from the passage between small sealing ring 7-1 and delivery port and realize draining, avoids containing larger hydraulic pressure in the 5-3 of annular outer seal chamber and causing the second piston 5 again to open.
As mentioned above, first piston 3 moves down, and after 1-2 at the bottom of the large sealing packing ring 5-1 on the second piston 5 and case realizes sealing, the first functional element 3-2 and the second functional element 7-2 interacts and makes embedded sleeve pipe 7 up mobile and compression reseting spring 7-3.
Embodiment two
As shown in Figure 6, Figure 7, the difference of the present embodiment and embodiment one is, the first functional element 3-2 realized when embedded sleeve pipe 7 moves up and down is different from the embodiment of the second functional element 7-2.The first functional element 3-2 of the present embodiment is the first inserted link 3-2-2 be arranged at bottom first piston 3, second functional element 7-2 is fixed on the lever construction 7-2-1 on the second piston 5, second side direction of this lever construction 7-2-1 is downward stretches out the second inserted link 7-2-2 and this second inserted link 7-2-2 is fixed on embedded sleeve pipe 7, when this first inserted link 3-2-2 moves down by first side of lever construction 7-2-1 toward pressing down thus making the second inserted link 7-2-2 drive embedded sleeve pipe 7 up to move.Lever construction 7-2-1 first side is provided with the jack 6-2-2 for accommodating first inserted link 3-2-2, and when first piston 3 moves up, the first inserted link 3-2-2 can depart from the jack 6-2-2 in lever construction 7-2-1.
Embodiment three
As shown in Figure 8, Figure 9, the difference of the present embodiment and embodiment one is, is also that the first functional element 3-2 of realizing when embedded sleeve pipe 7 moves up and down is different from the embodiment of the second functional element 7-2.First functional element 3-2 is the first tooth bar 3-2-2 ' be arranged at bottom first piston 3, second functional element 7-2 is a gear structure 7-2-1 ' being fixed on the second piston 5, the side of this gear structure 7-2-1 ' extends the second tooth bar 7-2-2 ' downwards and this second tooth bar 7-2-2 ' is fixed on embedded sleeve pipe 7, engages driven gear structure 7-2-1 ' and rotate thus make the second tooth bar 7-2-2 ' drive embedded sleeve pipe 7 up to move when this first tooth bar 3-2-2 ' moves down.
Above-mentioned explanation illustrate and describes the preferred embodiments of the present invention, as previously mentioned, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in invention contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
