Abstract
The utility model relates to a hydraulic control pipeline connecting and sealing device in a hydraulic device, in particular to a bow type gasket. The sides of the bow type gasket are designed in a bow-shaped structure which is composed of a front compact face, a back compact face, an outer compact face and an inner compact face, a through hole is formed in the center of the gasket, and the gasket can be made of elastic rubber, metal, plastic or composite materials. The bow type gasket achieves good adjusting performance of radial contact sealing force, meets high pressure sealing requirements of a hydraulic pipeline, and overcomes the defects of the poor adjusting performance of the radial contact sealing force of the existing gasket and short service life after scratching damages.
Description
Technical field:
The utility model relates to liquid controling pipe line connection seal arrangement, particularly a kind of bow grommet type seal in a kind of hydraulic equipment.
Background technique:
Hydraulic equipment is being played the part of more and more important role in modern industry, hydraulic line is the important component part of hydraulic equipment, how to realize that being tightly connected of hydraulic line and hydraulic equipment main body is the important content of hydraulics research always.Existing hydraulic line sealing configuration more complicated, most elastic caoutchouc Sealings of O type or rectangular cross-section that adopt are realized sealing, and the radially contact sealing force of the Sealing property adjusted is poor, and after the scraping damage, working life is short.Therefore be necessary to design a kind of simple in structure, radially contact the good seal configuration of sealing force adjustability, satisfy the high pressure sealing requirement of hydraulic line.
The model utility content:
The technical problems to be solved in the utility model provides a kind of bow grommet type seal, and it is good that this device has realized radially contacting the sealing force property adjusted, and satisfies the high pressure sealing requirement of hydraulic line.The radially contact sealing force property adjusted that has overcome existing Sealing is poor, scraping damage short deficiency in rear working life.
Technical solution adopted in the utility model is: a kind of bow grommet type seal, sealing pad lateral layout archwise structure, bow-shaped structural is made of front seal face, rear seal face, external sealed face and inner sealing surface, sealing pad center has through hole, and the sealing pad can adopt elastic caoutchouc, metal, plastics or composite material to make.
The beneficial effects of the utility model are: the utility model is owing to be designed to bow-shaped structural, thereby has and radially contact sealing force and adjust the good advantage of property, and simple and reliable for structure, sealing load is high, satisfies the high pressure sealing requirement of hydraulic line.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that a plurality of the utility model are used in combination schematic representation.
Embodiment:
As shown in Figure 1, a kind of bow grommet type seal, sealing pad lateral layout archwise structure, bow-shaped structural is made of front seal face 1, rear seal face 2, external sealed face 3 and inner sealing surface 4, sealing pad center has through hole, and the sealing pad can adopt elastic caoutchouc, metal, plastics or composite material to make.
In use, front seal face 1 and rear seal face 2 bear axial pre tightening force, and the utility model produces distortion under the effect of axial pre tightening force, realize the contraction of endoporus and the expansion of external diameter, and then realize being tightly connected.
In order to guarantee the sealing of arc sealing gasket, usually a plurality of arc sealing gaskets are used in combination, as shown in Figure 2, improve the overall sealing performance that is tightly connected.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
