Abstract
The utility model discloses a disk seat of spherical check valve for install in the valve body of spherical check valve, the disk seat is a hollow columnar body, and the outside sets up an annular groove, and disk seat right side opening part is a tubaeform inner chamber that inwards tightens up, and inwards extension is first cylindrical inner chamber, and the left side opening part is the cylindrical inner chamber of second, and the aperture ratio of the cylindrical inner chamber of second is big than the aperture of the first cylindrical inner chamber of second, sets up a steel ball in the cylindrical inner chamber of second, and the steel ball is located the right side of the cylindrical inner chamber of second, and the left side of steel ball sets up a spring, two bosss that the left side of spring set up through disk seat left side opening part support, the symmetry excision two sections circular-arc cylinders of cylinder form the lateral wall opening and are used for the liquid outflow on. The utility model has the advantages of simple structure, excellent in use effect, the spare part disk seat's of check valve life is longer, has saved the cost.
Description
Technical Field
The utility model relates to a disk seat of spherical check valve installs in the valve body of spherical check valve, belongs to check valve technical field.
Background
The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. Check valves are also known as check valves or check valves. In air conditioning equipment, because the refrigerant medium needs directional flow, so can use check valve, but the valve seat design life-span of check valve among the prior art is limited, often leads to the fact the check valve to damage because of wearing and tearing seriously after the use.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a disk seat of a spherical one-way valve, which solves the problem of short service life of the disk seat of the one-way valve in the prior art.
The technical scheme of the utility model as follows:
the utility model provides a disk seat of spherical check valve for install in the valve body of spherical check valve, the disk seat is a hollow columnar body, and the outside sets up an annular groove, and disk seat right side opening part is a tubaeform inner chamber that inwards tightens up, inwards extends to first cylindrical inner chamber, and the left side opening part is the cylindrical inner chamber of second, and the aperture ratio of the cylindrical inner chamber of second is big than the aperture of the first cylindrical inner chamber, sets up a steel ball in the cylindrical inner chamber of second, and the steel ball is located the right side of the cylindrical inner chamber of second, and the left side of steel ball sets up a spring, two bosss that the left side of spring set up through disk seat left side opening part support, two sections circular-arc cylinders of symmetry excision form the lateral wall opening and are used for the liquid outflow on.
The inner diameter of the spring at one side close to the steel ball gradually shrinks.
The utility model discloses the beneficial effect who reaches:
the utility model has the advantages of simple structure, excellent in use effect, the spare part disk seat's of check valve life is longer, has saved the cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, a disk seat of spherical check valve for install in the valve body of spherical check valve, the disk seat is a hollow columnar body, the outside sets up an annular groove 1, disk seat right side opening part is a tubaeform inner chamber 2 that inwards tightens up, inwards extend to be first cylindrical inner chamber 3, the left side opening part is second cylindrical inner chamber 4, the aperture ratio of second cylindrical inner chamber 4 is big than first cylindrical inner chamber 3's aperture, set up a steel ball 5 in the second cylindrical inner chamber 4, steel ball 5 is located the right side of second cylindrical inner chamber 4, the left side of steel ball 5 sets up a spring 6, two bosss 7 that disk seat left side opening part set up are passed through in the left side of spring 6 support, two sections circular-arc cylinder of symmetry excision form the lateral wall opening and are used for the liquid outflow on the disk seat that corresponds on the second cylindrical inner chamber 4.
The inner diameter of the spring 6 on the side close to the steel ball gradually shrinks.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
