Description
Technical field
This utility model is related to engineering machinery field, more particularly to a kind of sealing dress being applied to forklift fuel tank cover plate
Put.
Background technology
Forklift fuel tank is the vitals of fork truck.Tank cover on the market has two kinds of class rectangle and circle, class square at present
Shape tank cover mainly needs to arrange according to actual size.As shown in figure 1, known forklift fuel tank cover plate seal form is：Spiral shell
Bolt 2 ' passes through tank cover 1 ' and fuel tank 3 ' end face upper screwed hole 31 ' to be spirally connected installation, and lock sealing pad is pressed on fuel tank 3 ' end face；
Because tank cover 1 is directly mounted on the large end face of fuel tank 3 ' end face, screwed hole 31 ' be through hole, in fuel tank 3 ' oil gas easily from
Ooze out at screw thread.Further, since fuel tank 3 ' end face is large end face, typically do not give machining, with the bulk life of current existing process
Produce, flatness is relatively difficult to ensure card, therefore the phenomenon that fluid can be oozed out with sealing gasket joint from fuel tank 3 ' end face.
Content of the invention
The purpose of this utility model is to provide that a kind of to have good sealing effectiveness, structure simple, easy to process, general
The good sealing device being applied to forklift fuel tank cover plate of property.
For achieving the above object, technical solution of the present utility model is：
This utility model is a kind of sealing device being applied to forklift fuel tank cover plate, including fuel tank, annular flange dish, annular
Sealing gasket, tank cover, multiple flange face bolt；Described annular flange dish is fixedly mounted in the through hole of fuel tank end face,
Multiple obstructed screwed holes are offered on annular flange dish；Described tank cover is sealed on annular flange dish top surface, in fuel tank cap
It is provided with Gask-O-Seal between plate and annular flange dish, tank cover offers multiple through holes, multiple flange face bolts divide
Not Chuan Guo the through hole of tank cover, after the through hole of Gask-O-Seal with annular flange dish on multiple obstructed screw hole.
The bottom of described annular flange dish penetrates the through hole of fuel tank end face, and the lower surface of annular flange dish is located at fuel tank end
The lower section of face inwall, the bottom of annular flange dish has a cascaded surface, and this cascaded surface is resisted against on the end face of fuel tank and annular
Ring flange is sealed by way of welding and is fixed on fuel tank end face.
By analysis, there is problems with the forklift fuel tank cover plate commonly used：
（1）In forklift fuel tank, oil oozes out problem at screw thread；
（2）The tank cover of forklift fuel tank is installed on fuel tank end face, and because possible fuel tank end face is large end face, flatness is difficult
In ensureing the fluid that causes from fuel tank end face and sealing gasket joint bleeding.
（3）Solving（1）And（2）Under conditions of problem, provide a kind of optimal solution.Sealing device is made not only to have
Good sealing effectiveness, and structure simple it is easy to processing, versatility is good.
For solving the above problems, this utility model considers below scheme：
（1）For solve problem（1）, because screw thread adopts blind hole or applies fluid sealant, because applying after fluid sealant, tank cover exists
There is inconvenience disassembling, assembling and replacing filter element after installing first more, and need bolt to be changed and gluing again after bolt pine, therefore consider
Screw thread adopts blind hole to design.
（2）For solve problem（2）It is considered to using small end face flange plate structure or using the plane essence improving fuel tank large end face
Degree, because of massive plate bending weldment, flatness relatively it is difficult to ensure that, if the plane precision directly improving fuel tank large end face may be made
Become the direct increase of relatively costly amplitude, therefore adopt small end face ring flange method, that is, increase a counter flange disk.
（3）For solve problem（3）, optimize following some：
1. the tank cover because occurring on the market at present have class rectangle and circular two kinds it is considered to certain situation of fuel tank endogenous cause of ill
Under, in the case of having certain pressure in fuel tank, from the deformation of tank cover, the quality of the stressing conditions of bolt and shaken
Swing at the seal line of fluid sputtering circumferential length considering, therefore from circular tank cover, corresponding ring flange is annular flange
Disk.
2. ring flange setting certain thickness, has certain inhibition to the concussion fluid in fuel tank.
After such scheme, this utility model has advantages below：
1）Ring flange screwed hole is obstructed screwed hole, it is to avoid the probability that pressure oil gas overflows at screw thread.
2）Annular flange dish is annular, and mounting plane is little compared with fuel tank face, and through processing, flatness preferably, makes tank cover
Stress is more uniform, sealed reliable.
3）Annular flange dish has certain thickness, has certain inhibition to the concussion fluid in fuel tank.
4）This utility model sealed reliable, annular flange dish can determine common-use size according to different demands, thus carrying out phase
Close the universal standardization design of application, having the design of the related application universal standard may.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Brief description
Fig. 1 is the forklift fuel tank cover plate sealed structure chart commonly used；
Fig. 2 is three-dimensional exploded view of the present utility model；
Fig. 3 is the sectional view at this utility model tank cover.
Specific embodiment
As shown in Figure 2 and Figure 3, this utility model is a kind of sealing device being applied to forklift fuel tank cover plate, including fuel tank 1,
Annular flange dish 2, Gask-O-Seal 3,4, six flange face bolts 5 of tank cover.
Described annular flange dish 2 is fixedly mounted in the through hole 11 of fuel tank 1 end face, uniformly opens in annular flange dish 2
It is provided with six obstructed screwed holes 21；Described tank cover 4 is arranged on annular flange dish 2 top surface and by annular flange dish 2 center
Hole 22 covers, and is provided with Gask-O-Seal 3, tank cover 4 offers six between tank cover 4 and annular flange dish 2
Through hole 41, six flange face bolts 5 be each passed through the through hole 41 of tank cover 4, after the through hole of Gask-O-Seal 3 with annular flange
Six on disk 2 obstructed screwed holes 21 are spirally connected.
In the present embodiment, the bottom of described annular flange dish 2 penetrates the through hole 11 of fuel tank 1 end face, annular flange dish 2
Lower surface be located at the lower section of fuel tank 1 end face inwall, the bottom of annular flange dish 2 has a cascaded surface 23, this cascaded surface 23
It is resisted against on the end face of fuel tank 1 and annular flange dish 2 is sealed by way of welding and is fixed on fuel tank 1 end face.
Operation principle of the present utility model：
Described annular flange dish 2 upper surface it is ensured that flatness, solves tank cover 4 and is installed on through machining
Fuel tank 1 end face, because possible fuel tank 1 end face is large end face, flatness is it is difficult to ensure that the fluid causing is from fuel tank 1 end face and annular
Sealing gasket 3 joint bleeding；And annular flange dish 2 is welded on fuel tank 1, there is certain thickness, and a part is placed in oil
Inside case, solve the problems, such as good sealing；Annular flange dish 2 has certain thickness, has one to the concussion fluid in fuel tank 1
Fixed inhibition；Tank cover 4 is positioned on Gask-O-Seal 3, by 5 groups of lock sealings of six flange bolts and be uniform ring
Shape, makes tank cover 4 compare uniform force under conditions of class rectangle cover plate oily certain pressure in fuel tank 1 after locking, sealing can
By solving the problems, such as tank cover 4 uniform force.
Emphasis of the present utility model is that：Increase an annular flange dish.
The above, only this utility model preferred embodiment, therefore this utility model enforcement can not be limited with this
Scope, the equivalence changes made according to this utility model claim and description and modification, all should still belong to this reality
In the range of being covered with new patent.
