Valve for preventing distortion

1. A valve comprising:

a metal member configured to have at least two sub metal members;

a main body; and

a liner,

wherein the at least two sub metal members are included in the main body, and the main body is formed of plastic,

wherein the at least two sub metal members surround the liner, the liner includes a liner body member and a liner flange member formed at an end part of the liner body member, at least one of the at least two sub metal members includes a sub metal body member and a sub metal flange member formed at an end part of the sub metal body member, and the main body includes a main body member and a main body flange member formed at an end part of the main body member,

wherein a width of the sub metal flange member is larger than a width of the liner flange member, and the sub metal flange member surrounds the liner body member while the sub metal flange member is disposed behind the liner flange member.

2. The valve of claim 1 , wherein the main body includes a first sub main body and a second sub main body, and the metal member includes a first sub metal member and a second sub metal member,

and wherein the first sub metal member includes a 1-1 sub metal body member surrounding half of a first liner body member, a 1-2 sub metal body member surrounding the other half of the first liner body member, a 1-1 sub metal combination member connected to one side of the 1-1 sub metal body member, a 1-2 sub metal combination member connected to one side of the 1-2 sub metal body member, a 1-1 sub metal flange member connected to the other side of the 1-1 sub metal body member and a 1-2 sub metal flange member connected to the other side of the 1-2 sub metal body member, and

the second sub metal member includes a 2-1 sub metal body member surrounding half of a second liner body member, a 2-2 sub metal body member surrounding the other half of the second liner body member, a 2-1 sub metal combination member connected to one side of the 2-1 sub metal body member, a 2-2 sub metal combination member connected to one side of the 2-2 sub metal body member, a 2-1 sub metal flange member connected to the other side of the 2-1 sub metal body member and a 2-2 sub metal flange member connected to the other side of the 2-2 sub metal body member.

3. The valve of claim 1 , wherein the main body includes a first sub main body, a second sub main body and a third sub main body, and the metal member includes a first sub metal member included in the first sub main body, a second sub metal member included in the second sub main body and a third sub metal member included in the third sub main body,

and wherein a sub main body combination member of the first sub main body and a sub metal combination member of the first sub metal member form a first sub valve combination member, a 2-1 sub main body combination member of the second sub main body and a 2-1 sub metal combination member of the second sub metal member form a 2-1 sub valve combination member, a 2-2 sub main body combination member of the second sub main body and a 2-2 sub metal combination member of the second sub metal member form a 2-2 sub valve combination member, a sub main body combination member of the third sub main body and a sub metal combination member of the third sub metal member form a third sub valve combination member,

the 2-1 sub valve combination member is combined with the first sub valve combination member, and the 2-2 sub valve combination member is combined with the third sub valve combination member.

4. The valve of claim 1 , wherein the sub metal body member and the sub metal flange member surround an outer surface of the liner body member,

wherein the main body flange member surrounds an outer surface of the sub metal flange member, and

wherein a size of the sub metal flange member is larger than a size of the liner flange member.

5. The valve of claim 1 ,

wherein a fluid flow space through which fluid flows is formed in the liner, the liner is formed of fluorine resin.

6. The valve of claim 5 , wherein the liner flange member, the sub metal flange member and the main body flange member form one flange.

7. The valve of claim 5 , wherein at least one first hole, into which a fixing member is inserted to combine the valve with a pipe, and at least one second hole, in which melt plastic is filled when an insert molding is performed, are formed on the sub metal flange member.

8. The valve of claim 5 , wherein each of the liner, the sub at least two metal members and the main body is in a body, the sub metal members surround whole of the liner body member, the sub metal flange member has a semi-circle, and a groove curve line of the sub metal flange member covers a half of the liner body member.

9. The valve of claim 5 , wherein the fluid flow space has a streamlined shape from an inlet in a direction from the inlet to the opening-closing member or from an outlet in a direction from the outlet to the opening-closing member.

10. The valve of claim 5 , wherein a resin layer is formed between the liner and the metal member,

and wherein material of the resin layer is identical to material of the main body.
