Embodiment
The utility model embodiment provides a kind of electro-hydraulic hull valve, close at least solving the electro-hydraulic hull valve of prior art
Seal the relatively low technical problem of reliability.
In order to solve the above-mentioned technical problem, technical scheme general thought provided by the utility model is as follows：
In the technical scheme of the utility model embodiment, a plane of flap in the prior art is divided into two differences
Plane, TPI sealing ring is set, and then regard the plane as soft seal region, another is put down in a plane
The metal sealing block of hard is set on face, and then using the plane as hard sealing area, so pass through two kinds of soft or hard different materials
Material realizes the double containment form of electro-hydraulic hull valve primary seal (or valve face sealing), so as to solve electro-hydraulic hull valve sealed reliable
The relatively low technical problem of property, realizes the technique effect for improving electro-hydraulic hull valve sealing reliability.
Technical solutions of the utility model are described in detail below by accompanying drawing and specific embodiment, it should be understood that this
Specific features in application embodiment and embodiment are the detailed description to technical scheme, rather than to the application
The restriction of technical scheme, in the case where not conflicting, the technical characteristic in the embodiment of the present application and embodiment can be mutual group
Close.
The terms "and/or", only a kind of incidence relation for describing affiliated partner, expression may have three kinds of passes
System, for example, A and/or B, can be represented：Individualism A, while A and B be present, these three situations of individualism B.In addition, herein
Middle character "/", it is a kind of relation of "or" to typically represent forward-backward correlation object.
Fig. 1 is refer to, is the diagrammatic cross-section of electro-hydraulic hull valve in the utility model embodiment.As shown in figure 1, the electro-hydraulic side of a ship
Side valve comprises at least valve body 1, flap 2, valve rod 5, counter balance pocket piston 6, bonnet 12, valve seat 13, bolt 14, spirotallic gasket 28 and butterfly
Shape spring 17.Further, electro-hydraulic hull valve can also include the 3rd O-ring seal 29, the 3rd packing material 27, the 3rd filler pressure
Lid 15, bypass valve rod 10, plug screw 11, outer nut 16, piston 18, reduction gearing 19, end cap 20, bent axle 21, connecting rod cap 22, connecting rod
23rd, little gear 24, piston-rack 25, mounting seat 26 and spacing ring 8.Wherein, the connected mode of above-mentioned all parts and function with
Connected mode is similar with function in the prior art, therefore does not just repeat one by one in detail herein.
Due in the prior art only double containment is employed between bonnet 12 and valve rod 5, therefore cause sealing reliability compared with
It is low.In order to solve the relatively low technical problem of sealing reliability, in the utility model embodiment, as depicted in figs. 1 and 2, increase
The double containment of primary sealing area.
Specifically, the flap 2 in the utility model embodiment includes two different planes, two as shown in Figure 2
Plane.TPI sealing ring 34 is set in the plane to keep left in fig. 2.TPI is soft material,
Therefore region the utility model of TPI sealing ring 34 is set to be referred to as soft seal region.And it is flat to be kept right in Fig. 2
Metal sealing block 35 is then set on face.Because metal is hard material, therefore set this practicality of region of metal sealing block 35 new
Type is then referred to as hard sealing area.Aluminium, copper, iron or other composition metals, the utility model can be selected in the material of metal sealing block 35
It is not particularly limited.
Primary seal compared to the electro-hydraulic hull valve of prior art uses single seal form of hard metal sealing block, due to soft
The TPI sealing ring of matter is flexible, and seal operation torque is smaller, so can be hermetically more tight, therefore,
The double containment closed using the scleroma of above two material softer improves the sealing reliability of electro-hydraulic hull valve as primary seal.
Further, why the utility model uses the double containment of soft or hard combination, rather than is by primary seal is completely set up
TPI sealing ring, reason are：TPI is close will to be deformed upon more than 280 DEG C, at most more than 600
DEG C will decompose, thus in order to ensure in high temperature environments, even in the case of catching fire primary seal sealing reliability, retain
One plane sets metal sealing block.Therefore, under normal circumstances, for primary seal, TPI sealing ring 34
Play main seal, metal sealing block 35 plays secondary seal；And work as and high temperature occur, situation of catching fire, metal sealing block 35
Play main seal, TPI sealing ring 34 plays secondary seal, therefore ensures that primary seal in high-temperature condition
Under sealing reliability.
Further, as shown in Fig. 2 being located in soft seal region in plane, in TPI sealing ring 34 also
The 4th O-ring seal 4 is provided with, further strengthens the sealing function in soft seal area.In the plane that hard sealing area is located at,
Reinforced type flexible graphite metal wave tooth composite-gasket 3 is additionally provided with metal sealing block 35.Reinforced type flexible graphite has higher
Resistance to elevated temperatures, so reinforced type flexible graphite metal wave tooth composite-gasket 3 further enhances the fire resistance of primary sealing area.
