First and second mounting posts are provided on the valve housing on opposite sides of the opening and extend away from the opening. Each mounting post has a transverse bore formed therein.

대표청구항 ▼

1. A check valve comprising: a valve housing defining a valve opening and a web extending across the valve opening;first and second mounting posts provided on the valve housing on opposite sides of the opening and extending away from the opening, each mounting post having a transverse bore formed therein, the end of the transverse bore remote from the valve opening being at least partially closed;a central mounting post mounted to the web and extending away from the valve opening, the central mounting post having a first bore extending in a longitudinal direction and a second bore formed transversely therethrough, the second bore being aligned with the transverse bores provided in the first and second mounting posts;a first hinge pin mounted between the transverse bore of the first mounting post and the second, transverse bore of the central mounting post;a second hinge pin mounted between the transverse bore of the second mounting post and the second, transverse bore of the central mounting post;a hinge pin retaining element arranged between adjacent ends of the first and second hinge pins within the second, transverse bore of the central mounting post;a fastener received in the longitudinal bore of the central mounting post for fastening the central mounting post to the web and maintaining the hinge pin retaining element between the adjacent ends of the first and second hinge pins; anda pair of flapper elements pivotably mounted to first and second hinge pins for rotation between an open position in which they permit fluid flow through the opening and a closed position in which they prevent fluid flow through the opening. 2. A check valve as claimed in claim 1, wherein the first and second mounting posts are formed integrally with the valve housing. 3. A check valve as claimed in claim 1, wherein the end of at least one of the transverse bores of the first and second mounting posts is fully closed, for example being a blind bore. 4. A check valve as claimed in claim 1, wherein the at least one transverse bore of the first and second mounting posts is partially closed by a wall having an aperture therethrough to provide access to an end of a respective hinge pin. 5. A check valve as claimed in claim 1, wherein the hinge pin retaining element is formed by a portion of the central mounting post fastener. 6. A check valve as claimed in claim 1, wherein the hinge pin locking member is separate from the central mounting post fastener. 7. A check valve as claimed in claim 1, wherein the central mounting post is received in a recess formed in a surface of the web. 8. A check valve as claimed in claim 1, wherein the central mounting post comprises locating means. 9. A check valve as claimed in claim 1, wherein the central mounting post extends sufficiently from the web so as to form a stop for the flapper elements in their open position. 10. A check valve as claimed in claim 1, further comprising a plug received within the transverse bore of a respective first and second mounting post. 11. A check valve as claimed in claim 10, wherein the plug is made from a stronger, more durable or harder material than that of the respective mounting post. 12. A check valve as claimed in claim 10, wherein the plug receives an end of the respective hinge pin. 13. A check valve as claimed in claim 12 wherein the plug comprises a cup like portion having a cylindrical wall and an end wall which receive the end of the respective hinge pin and, optionally further comprising a rim portion for engaging an inwardly facing surface of the mounting post around the mounting post transverse bore. 14. A method of assembling a check valve as claimed in claim 1 comprising the steps of: a) assembling the first and second flapper elements to the first and second hinge pins and the central mounting post, with ends of the first and second hinge pins retracted into the transverse bore of the central mounting post;b) positioning the assembly between the first and second mounting posts, with the first and second hinge pins aligned with the transverse bores of the first and second mounting posts;c) moving second ends of the first and second hinge pins into the transverse bores of the first and second mounting posts;d) positioning the hinge pin retaining element between the first ends of the first and second hinge pins to prevent the hinge pins from retracting from the transverse bores of the first and second mounting posts; ande) fastening the fastener within the longitudinal bore of the central mounting post to fasten the central mounting post to the web and to retain the hinge pin retaining element in its position. 15. A method as claimed in claim 14, wherein the hinge pin retaining element is a part of the fastener member whereby steps d) and e) are effected simultaneously.
