Abstract

The utility model provides a O type packing ring, include: a gasket body having an annular groove at one end thereof coaxial with the through-hole of the gasket body such that the end of the gasket body is configured into an inner skirt and an outer skirt. According to the utility model discloses a O type packing ring can produce tension after the pressurized to increase and valve opening inner wall frictional force, the valve pad can not drop, has guaranteed the safe handling of valve.

Description

O-shaped gasket

Technical Field

The utility model relates to a high pressure cleaning shower nozzle/spray technical field, specific O type packing ring that says so.

Background

The gasket that assembles in the valve on the existing market designs all to be the plain type, opens after the high pressure rush into the valve body when the valve, when closing the valve again rapidly, and the gasket drops very easily, leads to the valve to be out of order because of not sealed.

SUMMERY OF THE UTILITY MODEL

The present invention aims at solving at least one of the technical problems in the related art to a certain extent.

Therefore, an object of the utility model is to provide an O type packing ring can produce tension after the pressurized to increase and valve opening inner wall frictional force, the valve pad can not drop, has guaranteed the safe handling of valve.

According to the utility model discloses a O type packing ring, include: a gasket body having an annular groove at one end thereof coaxial with the through-hole of the gasket body such that the end of the gasket body is configured into an inner skirt and an outer skirt.

Advantageously, the ratio of the depth of the annular groove to the height of the gasket body is 3: 8.

Advantageously, the outer skirt is inclined outwardly.

Advantageously, the ratio of the thickness of the outer skirt to the wall thickness of the gasket body is 5: 13.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

Fig. 1 is a schematic view of an O-ring gasket according to an embodiment of the present invention;

fig. 2 is a cross-sectional view of fig. 1.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The O-ring according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the O-ring according to the present invention includes: the gasket body 100, one end (in the present invention, an upper end as shown in fig. 1 and 2) of the gasket body 100 has an annular groove 110 coaxial with the through hole 101 of the gasket body 100, so that the end of the gasket body 100 is configured into an inner skirt 111 and an outer skirt 112. Here, it should be noted that, when mounting, the open end of the annular groove 110 is directed to the high-pressure side. From this, after the valve opens high pressure and rushes into the valve body, when closing the valve again rapidly, according to the utility model discloses an O type packing ring can produce tension after the pressurized to increase and valve opening inner wall frictional force, the valve pad can not drop, has guaranteed the safe handling of valve.

Advantageously, the ratio of the depth of the annular groove 110 to the height of the gasket body 100 (i.e., the axial dimension of the gasket body 100) is 3: 8.

Advantageously, the outer skirt 112 is outwardly inclined (i.e., inclined in a direction from the axial center to the outer peripheral wall in the axial direction of the gasket body 100). From this, utilize and be according to the utility model discloses a O type packing ring can carry out elastic deformation's characteristics, makes it carry out interference fit with the valve opening, and the cooperation is more reliable, has further guaranteed the safe handling of valve. Advantageously, the ratio of the thickness of the outer skirt 112 to the wall thickness of the gasket body 100 is 5: 13.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
