Abstract
The invention discloses a kind of cement silo Sealing, comprise seal ring body, it is characterized in that: described seal ring body comprises interconnective upper seal and lower seal, described upper seal end face opening diameter is greater than lower seal end face opening diameter, the wall thickness of described upper seal end face is greater than the wall thickness of lower seal end face, in the middle part of seal ring body, be provided with some skeletons laterally.Described upper seal and lower seal adopt rubber material once-through.The invention solves the required Sealing used in two positions close in prior art different, need manufacture two Sealings, manufacture cost is higher, and needs two Sealings to be fixed installation when assembling, and installs and also extremely bothers, considerably increase the installation time of oil sealing, reduce the problem of manufacturing efficiency, provide a kind of structure simple, cost of production is lower, fast easy for installation, the cement silo Sealing of two oil sealing positions can be sealed simultaneously.
Description
Technical field
The present invention relates to a kind of Sealing, particularly relate to a kind of cement silo Sealing.
Background technique
Current cement silo has two oiling positions to need to be coated with oil not of the same race, a position is coated with gear oil, and another one position is coated with lubricating grease, because oiling is of different types, so the required Sealing used in these two positions is just completely different, need manufacture two Sealings, manufacture cost is higher, and needs two Sealings to be fixed installation when assembling, and installs and also extremely bothers, considerably increase the installation time of oil sealing, reduce manufacturing efficiency.
Summary of the invention
Different in order to solve the Sealing used required for two positions close in prior art, need manufacture two Sealings, manufacture cost is higher, and needs two Sealings to be fixed installation when assembling, and installs and also extremely bothers, considerably increase the installation time of oil sealing, reduce the problem of manufacturing efficiency, the invention provides a kind of structure simple, cost of production is lower, fast easy for installation, the cement silo Sealing of two oil sealing positions can be sealed simultaneously.
In order to solve the problem, the technical solution used in the present invention is:
A kind of cement silo Sealing, comprise seal ring body, it is characterized in that: described seal ring body comprises interconnective upper seal and lower seal, described upper seal end face opening diameter is greater than lower seal end face opening diameter, the wall thickness of described upper seal end face is greater than the wall thickness of lower seal end face, in the middle part of seal ring body, be provided with some skeletons laterally.
Aforesaid a kind of cement silo Sealing, is characterized in that: described upper seal and lower seal adopt rubber material once-through.
Aforesaid a kind of cement silo Sealing, is characterized in that: described skeleton adopts ferrous material to make.
Aforesaid a kind of cement silo Sealing, is characterized in that: described skeleton adopts U-shaped skeleton.
Aforesaid a kind of cement silo Sealing, is characterized in that: the angle between described upper seal and lower seal is greater than 90 degree.
The invention has the beneficial effects as follows: on cement silo Sealing of the present invention, seal end face opening diameter is greater than lower seal end face opening diameter, and the wall thickness of upper seal end face is greater than the wall thickness of lower seal end face, upper seal end face can be used for sealing gear oil, and lower seal end face can be used for packing grease, achieve a product to the sealing of position, cement silo two place, structure is simple, and cost of production is lower, assemble also very convenient simultaneously, substantially increase assembling speed.
Accompanying drawing explanation
Fig. 1 is cement silo Sealing overall structure schematic diagram of the present invention.
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1-2, a kind of cement silo Sealing, comprise seal ring body 1, described seal ring body 1 comprises interconnective upper seal 2 and lower seal 3, described upper seal 2 end face 4 opening diameter is greater than lower seal 3 end face 5 opening diameter, the wall thickness of described upper seal 2 end face 4 is greater than the wall thickness of lower seal 3 end face 5, is provided with some skeletons 6 in the middle part of seal ring body 1 laterally.
Described upper seal 2 and lower seal 3 adopt rubber material once-through.Angle between described upper seal 2 and lower seal 3 is greater than 90 degree.Described skeleton 6 adopts ferrous material to make.Described skeleton 6 adopts U-shaped skeleton.
On cement silo Sealing of the present invention, seal 2 end face 4 opening diameter is greater than lower seal 3 end face 5 opening diameter, the wall thickness of described upper seal 2 end face 4 is greater than the wall thickness of lower seal 3 end face 5, upper seal 2 end face 4 can be used for sealing gear oil, and lower seal 3 end face 5 can be used for packing grease, achieve a product to the sealing of position, cement silo two place, structure is simple, and cost of production is lower, assemble also very convenient simultaneously, substantially increase assembling speed.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
