Claims

A valve for adding resistance to the liquid,
A first valve member configured to have a tubular shape, having an upper surface including a slot at one end and an opening at the other end;
A valve that receives the first valve member and includes a case having an inlet facing the opening of the first valve member and an outlet facing the upper surface of the first valve member.

A second valve member configured to have a tubular shape, having an upper surface including a slot at one end and having an opening at the other end, the second valve engaging with the first valve member inside the case It further comprises a member,
The valve according to claim 1, wherein the upper surface of the second valve member is disposed at a distance from the upper surface of the first valve member.

Each of the first valve member and the second valve member is
A first hollow member comprising the upper surface having a first inner diameter and a first outer diameter larger than the first inner diameter;
A second hollow member connected to the first hollow member, having a second inner diameter larger than both the first inner diameter and the first outer diameter, and having a second outer diameter larger than the first outer diameter; Including
The first valve member and the second valve member interact with each other such that the first hollow member of the second valve member is received and supported within the second hollow member of the first valve member. The valve of claim 2, wherein the valve is configured to mate.

Each of the first valve member and the second valve member is a third hollow member connected to the second hollow member, and has a third inner diameter larger than both the second inner diameter and the second outer diameter. A third hollow member having a third outer diameter larger than the second outer diameter,
The first valve member and the second valve member interact with each other such that the second hollow member of the second valve member is received and supported within the third hollow member of the first valve member. The valve of claim 3, wherein the valve is configured to mate.

When the outer diameter of the first hollow member of the second valve member is larger than the inner diameter of the first hollow member of the first valve member, the first hollow member of the second valve member becomes the first valve. The valve according to claim 3 or 4, wherein the valve is not inserted into the first hollow member of the member.

The valve according to any one of claims 2 to 5, wherein the first valve member and the second valve member have the same shape.

The valve according to any one of claims 1 to 6, wherein the slot of the first valve member extends in a radial direction on the upper surface of the first valve member.

The slot of the first valve member is closed when the pressure acting on the liquid flowing into the case from the inlet of the case is a predetermined level or less, and flows into the case from the inlet of the case. The valve according to any one of claims 1 to 7, wherein the valve opens when a pressure acting on the liquid exceeds a predetermined magnitude.

The valve according to any one of claims 2 to 8, wherein the slot of the second valve member extends in a radial direction on the upper surface of the second valve member.

The slot of the second valve member is closed when the pressure acting on the liquid flowing into the case from the inlet of the case is a predetermined level or less, and flows into the case from the inlet of the case. The valve according to any one of claims 2 to 9, which opens when a pressure acting on the liquid exceeds a predetermined magnitude.

The valve according to any one of claims 1 to 10, wherein the case includes a first case having the inlet and a second case having the outlet.

The valve according to claim 11, wherein the first case and the second case are connected by screwing.
