Abstract
The utility model discloses a valve core of a one-way valve, the valve core is of an integral structure, the bottom is a cylindrical base, the head with tail wings is arranged above the base, the bottom is coaxial with the head, the tail wings are three, the three tail wings are uniformly distributed around the shaft of the valve core, and the included angle between the tail wings is 120 degrees; the outer side walls of the three tail wings are arc-shaped and are positioned on the same circle track, and the radius of the circle is the same as the inner diameter of the valve body of the check valve and is larger than the radius of the cylinder of the base; and a buffer section is respectively arranged at one end close to the base between the three tail wings, the buffer section is provided with two sections which are respectively an arc-shaped platform below and a conical buffer slope above, and the arc-shaped platform below is close to the cylinder of the base to form an upwards contracted platform. The utility model discloses a case is integrated into one piece, need not carry out the concatenation technology, can use with the disk seat cooperation in the valve body of check valve, can be so that the life of individual valve is longer, has practiced thrift the cost.
Description
Technical Field
The utility model relates to a case of check valve belongs to air conditioning equipment 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 case design life-span of the 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 using.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a valve core of a one-way valve, which is used for being installed in a valve seat of the one-way valve, the valve core is of an integral structure, the bottom of the valve core is a cylindrical base which is used for penetrating into an inner cavity of the valve seat to prevent liquid from flowing, the head with tail wings is arranged above the base, the bottom of the valve core is coaxial with the head, the tail wings are three, the three tail wings are uniformly distributed around the shaft of the valve core, and the included angle between the tail wings is 120 degrees; the outer side walls of the three tail wings are arc-shaped and are positioned on the same circle track, and the radius of the circle is the same as the inner diameter of the valve body of the check valve and is larger than the radius of the cylinder of the base; and a buffer section is respectively arranged at one end close to the base between the three tail wings, the buffer section is provided with two sections which are respectively an arc-shaped platform below and a conical buffer slope above, and the arc-shaped platform below is close to the cylinder of the base to form an upwards contracted platform.
As another scheme, the four tail wings are uniformly distributed around the axis of the valve core, and the included angle between the four tail wings is 90 degrees.
The utility model discloses the beneficial effect who reaches:
the utility model discloses a case is integrated into one piece, need not carry out the concatenation technology, can use with the disk seat cooperation in the valve body of check valve, can be so that the life of individual valve is longer, has practiced thrift the cost.

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 valve core of a check valve is used for being installed in a valve seat of the check valve, the valve core is of an integral structure, the bottom of the valve core is a cylindrical base 1, the base 1 is used for penetrating into an inner cavity of the valve seat to prevent liquid from flowing, a head with a tail wing 2 is arranged above the base 1, the bottom of the base is coaxial with the head, the tail wings 2 are three, the three tail wings 2 are uniformly distributed around the axis of the valve core, and the included angles between the tail wings 2 are 120 degrees; the outer side walls of the three tail wings 2 are arc-shaped and are positioned on the same circle track, and the radius of the circle is the same as the inner diameter of the valve body of the check valve and is larger than the radius of the cylinder of the base; one end of each of the three tail wings 2 close to the base is provided with a buffer section, the buffer sections are provided with two sections, namely a lower arc-shaped platform 3 and an upper conical buffer slope 4, and the lower arc-shaped platform 3 is close to the cylinder of the base to form an upward-contracting platform.
As another scheme, the tail wings 2 are four, and the four tail wings 2 are uniformly distributed around the axis of the valve core, and the included angle between the four tail wings 2 is 90 degrees.
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.
