Abstract
The invention discloses a hydraulic bidirectional sealing leather bowl. According to the hydraulic bidirectional sealing leather bowl, the bottom parts of two unidirectionally sealing leather bowls are made together back to back; an annular slot with a trapezoidal cross section is formed on the external surface of a round body of the leather bowl; a concave part is formed at the middle part of two ends of the leather bowl; the cross section from the central axis of the leather bowl to the sealing port of the leather bowl is Y-shaped; and the surface line of the leather bowl is round. By the hydraulic bidirectional sealing leather bowl which is simple in structure and convenient to manufacture, the phenomenon of arranging two leather bowls on one piston for bidirectional sealing can be avoided; accessories are reduced, the size is reduced, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of hydraulic bidirectional caulking gum leather cup for hydraulic 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 hydraulic system forward and when oppositely mobile, can both play the leather cup of seal action.
For achieving the above object, described hydraulic bidirectional caulking gum leather cup of the present invention, it is characterized in that: hydraulic bidirectional caulking gum leather cup is that the bottom with the leather cup of two one-way sealings leans against privately and is manufactured in together, it is trapezoidal circular groove that outer surface on the circular body of leather cup has the cross section, and there is depression at the middle part at the two ends of leather cup; With the central axis of leather cup become to the cross section of the sealing oral area of leather cup "
Y" shape, whole lines on surface be circular.
For the sealed mouth that makes hydraulic bidirectional caulking gum leather cup has elasticity, the described hydraulic bidirectional caulking gum leather cup 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 described hydraulic bidirectional caulking gum leather cup of the present invention is consistent.
Hydraulic bidirectional caulking gum leather cup of the present invention simple in structure, easily manufactured, adopt hydraulic bidirectional caulking gum leather cup after, avoided filling two leather cups at a piston and carried out two way sealed, reduced accessory, dwindled volume, reduced cost.
Description of drawings
Fig. 1 is the form structure schematic representation of the plan view of hydraulic bidirectional caulking gum leather cup of the present invention when keeping flat.
Fig. 2 is the structural representation of the sectional view of hydraulic bidirectional caulking gum leather cup of the present invention.
Embodiment
Hydraulic bidirectional caulking gum leather cup of the present invention is the bottom of the leather cup of two one-way sealings to be leaned against privately to be manufactured in together during fabrication, it is trapezoidal circular groove that outer surface on the circular body of leather cup has the cross section, and it is trapezoidal recess behind the fillet that there is the cross section at the middle part at the two ends of leather cup; With the central axis of leather cup become to the cross section of the sealing oral area of leather cup "
Y" shape, whole lines on surface be circular.
For the sealed mouth that makes hydraulic bidirectional caulking gum leather cup 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 hydraulic bidirectional caulking gum leather cup is consistent.
Hydraulic bidirectional caulking gum leather cup of the present invention is installed in the cylinder body or valve body that need to carry out two way sealed, the sealed mouth of hydraulic bidirectional caulking gum leather cup contacts with the inwall of cylinder body or valve body, and the bottom in the middle of the hydraulic bidirectional caulking gum leather cup contacts with the push rod on hydraulic bidirectional caulking gum leather cup both sides.After hydraulic oil enters cylinder body or valve body one end, promote hydraulic bidirectional caulking gum leather cup and move forward, promote push rod and move and work.When hydraulic oil enters in cylinder body or the valve body when promoting hydraulic bidirectional caulking gum leather cup from the reciprocal the other end, hydraulic bidirectional caulking gum leather cup backward mobile, to promote push rod also mobile and work backward.
When hydraulic bidirectional caulking gum leather cup of the present invention was used for gap adjustment valve, a hydraulic bidirectional caulking gum leather cup had replaced two leather cups and plunger.
