Abstract
The invention provides a shuttle-typed check valve, which solves the problem that the existing shuttle-typed check valve has low assembly and disassembly precision and poor reliability. A valve sleeve (1) and a valve flap (3) in a shell (4) form an enclosed chamber which is internally provided with a spring (2); the valve sleeve is provided with a hole (10); a valve shaft (9) is connected with the valve flap (3) and movably matched with a shaft sleeve (5) in the central hole of the valve sleeve (1); the shaft sleeve (5) is matched with a central hole thread and provided with a locking nut (6); the valve sleeve is connected with a precise matching ring (7) which is matched with a flow passage internal hole thread at one end of the shell (4); the end surface and/or the cylindrical surface of the valve flap (3) is hermetically matched with a valve seat (8) at the other end of the shell (4).
Description
Technical field:
The present invention is relevant with one-way valve.
Background technique:
Existing shuttle-type one-way valve structures complexity, spool and housing, the dismounting precision and the sealing reliability of mangetic core assembly are not high, cause the short and leakage in working life of valve.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, assembly precision height, reliable sealing shuttle type check valve.
The present invention is achieved in that
Shuttle type check valve of the present invention, valve pocket 1 in the housing 4 constitutes enclosed cavity with flap 3, spring 2 is arranged in the chamber, and porose 10 on the valve pocket, valve shaft 9 is connected with flap 3, with axle sleeve 5 in valve pocket 1 center hole movingly, axle sleeve 5 and center hole screw-internal thread fit have locking nut 6, and valve pocket is connected with precision-fit ring 7, precision-fit ring 7 cooperates with the runner inner hole thread of housing 4 one ends, the end face of flap 3 or/and the valve seat 8 of the cylinder and housing 4 the other ends be sealed and matched.
There is seal ring 11 to cooperate in the end face caulking groove of flap 3 with the end face seal of valve seat 8.
The end face of the end face of flap 3 or valve seat 8 is the metal hard-sealing face.
There are the seal ring 11 and the endoporus of valve seat 8 to be sealed and matched in the cylinder caulking groove of flap 3.
There are the end face or the cylinder of seal ring and flap 3 to be sealed and matched in the end face of valve seat 8 or the caulking groove of cylinder.
The length of thread engagement of precision-fit ring 7 and the runner endoporus precision section of being slidingly matched is greater than 20mm, and the length of thread engagement of the precision section of being slidingly matched of valve pocket 5 and valve shaft 9 is greater than 20mm.
The invention provides valve shaft 9 the be sealed and matched section long with axle sleeve 5; The longer precision-fit section of spool and valve body 4, fastening with the screw thread realization, realize the easy of dismounting, guarantee the coaxality of valve body, valve pocket, valve shaft, axle sleeve, flap, pipeline shaft axis, guarantee the perpendicularity of flap sealing surface and pipeline shaft axis, coincide with the balance of valve base sealing pair.Take multiple sealing means can both satisfy the seal request of valve, increase the selectivity of sealing pair and the adaptive scope of sealing pair.
