Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1-8, a fully-sealed corrosion prevention system with a drainage device for a flange valve comprises: two pipelines 1 that communicate each other, and two pipelines 1 pass through flange 2 and connect, and the junction of flange 2 covers simultaneously has sealing ring 3 and is provided with sealed cowling 4 in the flange 2 outside, and packs between sealed cowling 4 and the flange 2 and have the filler to the filler is used for preventing that flange 2 from rusting.
And the bottom of the sealing ring 3 is provided with a first drainage tube 31, the bottom of the sealing cover 4 is provided with a second drainage tube 41, and the two ends of the second drainage tube 41 are respectively connected with the first drainage tube 31 and the collecting device 5, so that the leaked gas and liquid of the flange 2 are collected by the collecting device 5, and the explosion risk is reduced.
Thus, in actual use, the leakage of the flange 2 is prevented by the sealing ring 3 from flowing out from other places except the first draft tube 31, and the sealing ring 3 has a guiding function to guide the leaked gas or liquid to the first draft tube 31 along the inner wall of the sealing ring 3.
And the first draft tube 31 and the second draft tube 41, which are communicated with each other, are provided so that the collecting device 5 is communicated with the flange 2, i.e., is not associated with the packing, and thus gas and liquid leaked from the flange 2 can be collected to reduce the explosion risk.
As shown in fig. 1-3, a valve 6 is disposed between two pipes 1, and the valve 6 is connected to the pipes 1 via a flange 2. Meanwhile, since the valve 6 has two open ends, at least two flanges 2 are provided, so that one end of the corresponding second drainage tube 41 is at least two inlets 411, and the other end of the second drainage tube 41 is an outlet 412, and the inlets 411 are communicated with the sealing ring 3.
Therefore, in the actual use process, the arrangement of the plurality of inlets 411 can realize that the gas and the liquid leaked by the flange 2 in the sealing cover 4 can be gathered in one second draft tube 41 and flow out, and the arrangement number of the second draft tubes 41 can be further reduced.
As shown in fig. 1 to 3, the filler is a foamed resin, and a plurality of injection heads 45 are provided outside the sealing cover 4 and the foamed resin is injected into the sealing cover 4 through the injection heads 45. Wherein the foam resin can be UV epoxy foam resin or PU epoxy foam resin.
Therefore, in the actual use process, six data can be selected and set, and other data can be set according to the actual situation. And through the setting of a plurality of injection heads 45, can accelerate injection time and make the filler fill more fully, simultaneously the foamed resin filling compare current paste or powder resin, foamed resin is more firm and difficult for droing so the guard time can be longer to the packing pressure also can be bigger and then can fill whole space.
As shown in fig. 6, the wire 32 is disposed on the inner wall of the sealing ring 3, the flange 2 includes a first casing 21 and a second casing 22, and the wire 32 covers the joint of the first casing 21 and the second casing 22, and is used for buffering the impact of leaked gas and liquid on the sealing ring 3 through the mesh of the wire 32.
Thus, during actual use, the mesh of wire 32 may be used to cushion the impact of leaking gas and liquid against the sealing ring 3. This is because the wire 32 acts as a barrier and also as a shunt, and the gas liquefies when it is cold, thereby reducing some atomization, and the liquid is relatively less dense than the gas.
Wherein the mounting structure of wire netting 32 does: first, the sealing ring 3 comprises a housing 33 and symmetrically arranged spacers 34, the spacers 34 are located inside the housing 33, and the wire 32 is arranged between the symmetrically arranged spacers 34. Simultaneously, the specific installation mode is as follows: the wire 32 is welded to the inner wall of the housing 33 and the gasket 34 is adhered to the inside of the housing 33.

Therefore in the in-service use process, compare current joint, integrated into one piece's installation is more convenient, and the joint can have the possibility that sealed effect is not good because of the reason of installation moreover, and integrated into one piece has then avoided this kind of condition.
Meanwhile, a first connecting plate 422 and a second connecting plate 432 are respectively arranged on the peripheral sides of the first sealing shell 42 and the second sealing shell 43, and the first connecting plate 422 and the second connecting plate 432 are connected through a fastener. Wherein the fastener can be a screw or a bolt, etc.
As shown in fig. 7 and 8, the collecting device 5 comprises a cover 51 and a barrel 52 for placing gas and liquid, the cover 51 is arranged on the barrel 52, an alarm 53 and a connecting pipe 55 are arranged on the cover 51, the connecting pipe 55 is communicated with the second drainage pipe 41, and the alarm 53 is used for knowing that the volume placed in the barrel 52 exceeds the standard and needs to be poured out.
The connection pipe 55 is also provided with a plurality of inflow ports, so that gas and liquid leaked from the flange 2 are collected in one connection pipe 55, and the number of the barrels 52 can be reduced.
Therefore, in the actual use process, the collecting device 5 is used for collecting gas and liquid leaked by the flange 2, and when the volume placed in the barrel body 52 exceeds the standard and needs to be poured out, the alarm 53 gives an alarm to remind a user of pouring out.
Meanwhile, in order to better know the volume placed in the barrel 52, as shown in fig. 7, a display screen 54 is added on the cover 51, and the liquid can be poured out when the cover is close to the barrel, so that the liquid can be poured out without exceeding every time, and the condition that leaked gas or liquid cannot flow out is avoided.
And a sealing member is provided between the cover 51 and the tub 52, and a handle 57 may be provided at the cover 51 in order to separate the cover 51 from the tub 52, as shown in fig. 7, so that a hand is placed on the handle 57, thereby opening the cover 51 by breaking the handle 57.

And wheels or a hand-held portion may be provided at the tub 52 to facilitate movement and holding of the tub 52.
Example two: this embodiment is substantially the same as the first embodiment, and is different from the first embodiment in that: as shown in fig. 4 and 5, the flange 2 alone is not provided with the valve 6, i.e. the flange 2 alone is protected against corrosion and leakage. Meanwhile, in order to accelerate the injection time and fill the filler more fully, a plurality of injection heads 45 can be arranged, wherein five injection heads are arranged, then another corresponding position is a second drainage tube 41, or six injection heads are arranged, and then the second drainage tube 41 is arranged on the cambered surface, namely the second drainage tube 41 is obliquely arranged. Meanwhile, other data can be set according to actual conditions.
