Abstract
The invention discloses a pressure bidirectional internal and external sealing rubber cap. According to the pressure bidirectional internal and external sealing rubber cap, the bottoms of two unidirectional sealing caps with internal and external sealing port parts are combined together back to back; the outer surface of a round body of the cap is provided with a ring-shaped slot of which the section is of a trapezoid shape or is of a rounded trapezoid shape; both ends of the cap are provided with ring-shaped grooves; the shape of the section of the cap is formed by transversely connecting the lower ends of two groups of Ys, wherein each group of Ys comprises two Ys; and the integral surface line is of a round shape. After the pressure bidirectional internal and external sealing rubber cap which has a simple structure and is convenient to manufacture is adopted, the condition that two caps are arranged on one piston to carry out bidirectional sealing is avoided, fittings are reduced, the volume is shortened and cost is reduced.
Description
Technical field
The present invention relates to the two-way inside and outside caulking gum leather cup of a kind of air pressure for pressure system.
Background technique
The leather cup that uses now all is one-way sealing basically, causes leather cup can not play seal action when mobile to opposite direction.
Summary of the invention
The purpose of this invention is to provide in a kind of cylinder body in pressure system forward and when oppositely mobile, can both play the leather cup of seal action.
For achieving the above object, the two-way inside and outside caulking gum leather cup of described air pressure of the present invention, it is characterized in that: the two-way inside and outside caulking gum leather cup of air pressure is that the bottom with the leather cup of two one-way sealings that inside and outside sealing oral area arranged leans against privately and is manufactured in together, trapezoidal circular groove after the inner and outer surface on the circular body of leather cup has the cross section to be trapezoidal or fillet, there is annular groove at the two ends of leather cup; The shape in the cross section of leather cup by two "
Y" two groups of compositions laterally linking together of lower end, the bar of integral surface line is circular.
For the sealed mouth that makes the two-way inside and outside caulking gum leather cup of air pressure has elasticity, the two-way inside and outside caulking gum leather cup of the described air pressure of the present invention during fabrication resilient rubber of apparatus is made.
In order to increase the sealing of leather cup when positive and negative direction moves, the diameter of the sealed mouth end of the positive and negative direction of the two-way inside and outside caulking gum leather cup of described air pressure of the present invention is consistent.
The caulking gum leather cup was simple in structure, easily manufactured inside and outside air pressure of the present invention was two-way, behind the two-way inside and outside caulking gum leather cup of employing air pressure, had avoided filling two leather cups at a piston and had carried out two way sealed, had reduced accessory, had dwindled volume, had reduced cost.
Description of drawings
Fig. 1 is the form structure schematic diagram of the plan view of the two-way inside and outside caulking gum leather cup of air pressure of the present invention when keeping flat.
Fig. 2 is the structural representation of the sectional view of the two-way inside and outside caulking gum leather cup of air pressure of the present invention.
Embodiment
The two-way inside and outside caulking gum leather cup of air pressure of the present invention is that the bottom with the leather cup of two one-way sealings that inside and outside sealing oral area arranged leans against privately and is manufactured in together, trapezoidal circular groove after the inner and outer surface on the circular body of leather cup has the cross section to be trapezoidal or fillet, there is annular groove at the two ends of leather cup; The shape in the cross section of leather cup by two "
Y" two groups of compositions laterally linking together of lower end, integral surface lines circular.
For the sealed mouth that makes the two-way inside and outside caulking gum leather cup of air pressure has elasticity, the resilient rubber of apparatus is made during fabrication.In order to increase the sealing of leather cup when positive and negative direction moves, the diameter of the sealed mouth end of the positive and negative direction of the two-way inside and outside caulking gum leather cup of air pressure is consistent.
The two-way inside and outside caulking gum leather cup of air pressure of the present invention is installed in the cylinder body or valve body that need to carry out two way sealed, the external sealed oral area of the two-way inside and outside caulking gum leather cup of air pressure contacts with the inwall of cylinder body or valve body, and the interior sealing oral area of the two-way inside and outside caulking gum leather cup of air pressure is enclosed within on post or the bar.After pressurized gas entered cylinder body or valve body one end interior, pressurized gas promoted the two-way inside and outside caulking gum leather cup of air pressure and moves forward, promotes post or bar and move and work.After pressurized gas enters in cylinder body or the valve body from the opposite direction the other end of cylinder body or valve body, pressurized gas is from promoting in the other direction the two-way inside and outside caulking gum leather cup of air pressure, the two-way inside and outside caulking gum leather cup of air pressure backward mobile, to promote post or bar also mobile and work backward.
When the two-way inside and outside caulking gum leather cup of air pressure of the present invention is used for the air pressure telescopic cylinder, a two-way inside and outside caulking gum leather cup of air pressure only being installed on plunger rod in the body one by one, both reduced an annular groove of plunger rod, reduced again by a leather cup.
