Background technology
Main heat-exchanging part of the hydrogen cooler as steam turbine generator, internal heat water pipe are mild with Inlet and outlet water
The variation of cold and hot hydrogen temperature will appear expansion and contraction, and water pipe deforms under the effect of expanding with heat and contract with cold and is damaged in order to prevent,
Require hydrogen-cooled device that can freely be slid on the component being attached thereto.Since hydrogen is most light gas, permeability and diffusion
Property it is very strong, hydrogen gas leakage is easily caused in the pressure vessel for filling hydrogen.It, will with being continuously increased for hydrogen gas leakage amount
The output of generator is influenced, or even is set off an explosion, to cause safety accident, therefore, running generator is for hydrogen
Leakage rate have strict requirements.And current hydrogen-cooled device structure design, following defect is primarily present in terms of sealing structure：
First, in actual installation process, the sealing strip being easy to damage in vertical direction, field installation process is bad, operability also compared with
Difference leads to practical sealing effect and bad.Second, in actual use, when generator capacity increases, hydrogen pressure improves,
Requirement is then not achieved in its sealing effect completely.
Existing hydrogen-cooled device leakproofness effect is poor, and assembling is laborious, the sealing effect peace not up to standard that can seriously affect hydrogen-cooled device
Quan Xing.
Therefore, a kind of hydrogen-cooled device rubber sealing structure of invention is very necessary.
Utility model content
In view of the above technical problems, the utility model provides a kind of hydrogen-cooled device rubber sealing structure, close to solve hydrogen-cooled device
Envelope property effect is poor, assembles laborious problem.
A kind of hydrogen-cooled device rubber sealing structure, which is characterized in that the hydrogen-cooled device rubber sealing structure includes trip bolt, holds
Tube sheet, motor case, first seal, extrusion, attachment screw, pressing plate, second seal and cam；Plate is in the charge of through fastening spiral shell
Nail is fixed on motor case, and a cone tank is equipped on the inside of pressing plate, and the extrusion of taper is mounted on inside cone tank, the pressing plate
Side is threadedly coupled with attachment screw, is connected with a cam at the top of the attachment screw, the cam stretches into the extrusion
Portion and the extrusion inner wall are tangent, and the extrusion is respectively equipped with a second seal, first seal in both sides up and down, described
First seal, second seal section both sides are lozenges, lozenges and the motor of the first seal lower end
The lozenges of casing side is in contact, and the lozenges of the second seal upper end matches with the lozenges for being in the charge of plate side
It closes.
Preferably, extrusion described in taper is made of spring steel or elastic material.
Preferably, the attachment screw is rotated, the cam can push the extrusion upper end inwardly or outwardly to expand.
Preferably, the extrusion circular cone is tangent with the lozenges of the first seal, second seal respectively.
Compared with prior art, the utility model has the advantages that：The utility model is simple in structure, utilizes rotation
Cam extrusion extrusion, so that the sealing element of tapered squeezing part taper surface and its both sides is coordinated, form cuniform increase power structure, can
Sealing element is compressed, and pressing force can be adjusted by the screw that is rotatably connected, good seal performance is easy for installation.

Specific implementation mode
The utility model is described further below in conjunction with attached drawing：
Embodiment：
As shown in attached drawing 1,2, the utility model provides a kind of hydrogen-cooled device rubber sealing structure, which is characterized in that this is hydrogen-cooled
Device rubber sealing structure includes trip bolt 1, be in the charge of plate 2, motor case 3, first seal 4, extrusion 5, attachment screw 6,
Pressing plate 7, second seal 8 and cam 9；It is in the charge of plate 2 to be fixed on motor case 3 through trip bolt 1,7 inside of pressing plate is equipped with one
The extrusion 5 of cone tank, taper is mounted on inside cone tank, and 7 side of pressing plate is threadedly coupled with attachment screw 6, and attachment screw 6 pushes up
Portion is connected with a cam 9, and cam 9 stretches into that 5 inside of extrusion is tangent with 5 inner wall of extrusion, and about 5 both sides of extrusion are respectively equipped with
One second seal 8, first seal 4, first seal 4,8 section both sides of second seal are lozenges, the first sealing
The lozenges of 4 lower end of part is in contact with the lozenges of 3 side of motor case, the lozenges of 8 upper end of second seal and is in the charge of plate 2
The lozenges of side matches, and tapered squeezing part 5 is made of spring steel or elastic material, and be rotatably connected screw 6, and cam 9 can
