Abstract
A rubber ring pressure sealing device is composed of a tested component, a fixed joint and a sealing rubber ring. The sealing rubber ring is sleeved on the cylindrical surface of the tool withdrawal groove adjacent to the step plane on the tested component, and when sealing is completed, the sealing rubber ring is arranged in a cavity formed by the step plane of the component, the cylindrical surface of the tool withdrawal groove and the opening conical surface on the fixed joint.
Description
The technical field is as follows: the utility model provides a develop in rubber ring pressure seal device in gas pressure observes and controls field, especially relates to a rubber ring seal device that is used for pressure sensor components and parts to test.
Background art: at present, in the existing gas sealing technology, a sealing element is mostly arranged on a plane for sealing gas to increase the tightening force, and the yield strength of a sealing material is utilized to resist the pressure of the gas, so that the yield strength of the sealing material cannot be maximized when the tightening force is insufficient. Thus, leakage is inevitable and when the yield strength of the seal is insufficient to resist the pressure of the gas, the seal collapses and fails.
The invention content is as follows: in order to solve the defects of the prior art, the utility model aims to provide a rubber ring pressure seal device, especially at a rubber ring pressure seal device in pressure sensor components and parts test field. The utility model discloses in the use, do not need big tight power just can reach very good sealed effect, its biggest beneficial effect is the intensity of pressure that has utilized the tensile strength of sealing material to come the counter gas, and this just makes the increase of sealing capacity multiple, can reach the increase of quantity rank even.
The technical scheme is as follows: the utility model discloses constitute by components and parts, fixed joint, the sealed rubber ring of being surveyed. The sealing rubber ring is sleeved on the cylindrical surface of the tool withdrawal groove adjacent to the step plane on the tested component, the tested component is connected with the fixed joint through threads, the step plane of the tested component is tightly closed to the opening plane of the fixed joint, and the sealing rubber ring is tangent to the opening conical surface on the fixed joint and is guided into a cavity formed by the step plane of the tested component, the cylindrical surface of the tool withdrawal groove and the opening conical surface on the fixed joint.
Has the advantages that: the most beneficial effects are as follows:
1. no large tightening force is required to effectively seal the target gas.
2. The tensile strength of the sealing material is utilized to resist the pressure of gas, so that the sealing efficiency is multiplied.
Description of the drawings:
FIG. 1 is a view showing the construction of the present invention;
FIG. 2 is a block diagram of the present invention;
the specific implementation mode is as follows:
according to figure 1 shows the utility model discloses a constitution includes: tested components 1, fixed joint 2, sealing rubber ring 3. As shown in fig. 2, the sealing rubber ring 3 is disposed in a cavity defined by a step plane 4 of the device 1 to be tested, a cylindrical surface 5 and an opening conical surface 6 on the fixed connector 2. The sealing rubber ring 3 is tangent to a step plane 4 on the tested component 1 and is embedded and sleeved on a cylindrical surface 5 of the tested component 1, the tested component 1 is connected with the fixed joint 2 through threads, the step plane 4 is tightly closed to an opening plane 7 of the fixed joint 2, and the sealing rubber ring 3 is tangent to an opening conical surface 6 on the fixed joint 2.
