Abstract
The invention relates to a rubber gasket for a marine hatch cover presser. The rubber gasket comprises a gasket body made of rubber, a hole is arranged in the gasket body, two ends of the hole are respectively provided with a groove, and a metal sleeve pipe is further arranged at the position of the hole. The rubber gasket is small in compression deformation, has damping and limiting effects, and is difficult to crush, low in maintenance rate and long in service life.
Description
Technical field
The present invention relates to a kind of ship hatch board compactor rubber washer.
Background technique
As shown in Figure 1, be former ship hatch board compactor rubber washer, this ship hatch board compactor rubber washer substantially all adopts the one rubber parts, because the compressive strain of rubber is larger, damages by pressure easily in actual use, causes working life short, and maintenance is frequent.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of long service life, the ship hatch board compactor rubber washer that compressive strain is little.
For addressing the above problem, the technical solution adopted in the present invention is: ship hatch board compactor rubber washer, comprise that material is the packing ring body of rubber, offer a hole in the packing ring body, the two ends in hole respectively have a circular groove, and the diameter of circular groove is provided with a metal sleeve greater than the diameter in hole in the described hole, metal sleeve and hole wall fit, and the two ends of metal sleeve are extended down to respectively the diapire of circular groove.
The invention has the beneficial effects as follows: above-mentioned ship hatch board compactor rubber washer, compressive strain is little, has damping and spacing effect, is difficult for damaging by pressure long service life.
The relevant physical properties index of described ship hatch board compactor rubber washer is as follows: tensile strength 〉=15Mpa, elongation percentage 〉=420%, compression set rate 〉=18%, firmness change rate 〉=± 8 degree, tensile strength variance ratio≤22%, elongation change rate≤25%, low temperature brittleness 〉=-45 ℃.
Description of drawings
Fig. 1 is the former ship hatch board compactor rubber washer structural representation described in the background technique;
Fig. 2 is structural representation of the present invention;
Fig. 3 is mounting structure schematic representation of the present invention;
Among the figure: 1, metal sleeve, 2, circular groove, 3, the hole, 10, the hatchcover compactor, 11, locking nut, 12, the packing ring body.
Embodiment
Below by specific embodiment ship hatch board compactor rubber washer of the present invention is further described.
As shown in Figure 2, ship hatch board compactor rubber washer, comprise that material is the packing ring body 12 of rubber, offer a hole 3 in the packing ring body 12, the two ends in hole 3 respectively have a circular groove 2, and the diameter of circular groove 2 is provided with a metal sleeve 1 greater than the diameter in hole 3 in the described hole 3, metal sleeve 1 fits with hole wall, and the two ends of metal sleeve 1 are extended down to respectively the diapire of circular groove 2.
Working principle of the present invention is: as shown in Figure 3, packing ring body 12 is installed on the hatchcover compactor 10, by screwing of locking nut 11, packing ring body 12 power that is squeezed, by the effect of circular groove 2 in the packing ring body 12, packing ring body 12 has been played the effect of a damping, owing to also be provided with metal sleeve 1 in the hole 3, and the two ends of metal sleeve 1 are extended down to respectively the diapire of circular groove 2, and 11 pairs of packing ring bodies of locking nut 12 have also played spacing effect when producing extruding force.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
1. ship hatch board compactor rubber washer, comprise that material is the packing ring body of rubber, offer a hole in the packing ring body, it is characterized in that: the two ends in described hole respectively have a circular groove, the diameter of circular groove is greater than the diameter in hole, be provided with a metal sleeve in the described hole, metal sleeve and hole wall fit, and the two ends of metal sleeve are extended down to respectively the diapire of circular groove.
2. ship hatch board compactor rubber washer according to claim 1, it is characterized in that: described hole is positioned at the middle part of packing ring body, and is mutually concentric with the packing ring body.
