Description

A kind of Swing check valve
Technical field
The utility model relates to a kind of safety check, particularly a kind of Swing check valve.
Background technique
At present, on oil or natural gas line, using generally is traditional safety check, and traditional safety check adopts lifting structure, and its all-pass footpath is little; And the resistance of fluid is big, uses on oil or natural gas line, has influenced the transmission of oil or rock gas, is unfavorable for producing using; Simultaneously because its lifting structure that adopts, its sealing surface is rubbed and is damaged through regular meeting, and the life-span of Sealing is shorter, and it changes trouble very; Make maintenance cost expensive, the safety check that the while is traditional, it is by going up and down to realize its function; When pressure is excessive, easily the valve body infringement is leaked, cause the pollution of environment.
The model utility content
The goal of the invention of the utility model is: the problem to above-mentioned existence provides Swing check valve a kind of simple in structure, easy and simple to handle, convenient to use; Use this Swing check valve, flow resistance is little, and does not have throttling action; Bearing capacity is big, and the life-span is permanent, and is with low cost.
The technological scheme that the utility model adopts is following:
The utility model Swing check valve comprises valve body, and said valve body is a through-hole structure, and the sidewall of valve body is provided with the hole, and seals through valve gap, is provided with valve plate in the said valve body, and said valve plate is movably connected in the valve body, opens or close through hole.
Owing to adopted said structure, valve body adopts solid forging, and can bear has pressure rating more, and it is applied widely; Valve body is a through-hole structure, is convenient to through fluid, and the sidewall of valve body is provided with the hole, and seals through valve gap; Thereby make that spool can overall pulling down, reduce the workload of field maintenance effectively, thereby reduce maintenance cost, valve plate is movably connected in the valve body; Open or close through hole, make that whole safety check is the all-pass gauge structure, littler than the safety check flow resistance of routine, no throttling action; Simultaneously, this safety check adopts straight-through structure, reduces the erosion of medium to valve body, thereby increases its working life.
The utility model Swing check valve, said valve body internal fixation is connected with the shell type valve seat, and said valve plate is movably connected on the shell type valve seat, on the said valve plate seal ring is set.
Owing to adopted said structure, valve plate to be movably connected on the shell type valve seat, and seal ring be set on the valve plate; When needs carried out valve body, this valve plate and valve body were close to, and seal ring is arranged at wherein; When the valve plate pressurized, can compresses seal and valve seal, thus guarantee its sealing effect; The valve body internal fixation is connected with the shell type valve seat, makes that valve body and shell type valve seat are two independent parts, therefore makes its manufacturing be more prone to; And valve body is through solid forging, and applicable to various pressure ratings, using scope is wide.
The utility model Swing check valve, said shell type valve seat is fixed on the inwall of valve body through the bolt circle pin, and said shell type valve seat is through valve seals and valve seal.
Owing to adopted said structure, the shell type valve seat is fixed on the inwall of valve body through the bolt circle pin, and its structure is surely leaned on; Safe in utilization convenient, fix through the bolt circle pin, reduce its cost; The shell type valve seat passes through valve seals and valve seal, thereby guarantees the sealing effect between the two, guarantees that it is in the process of using; Can not leak, can be used safely and reliably.
The utility model Swing check valve disposes dust cover on one end of valve body.
Owing to adopted said structure; End at valve body disposes dust cover, particularly at entrance point configuration dust cover, can prevent that dust and impurity from entering into valve inner; Thereby influence the sealing between valve plate and the valve body; Avoid when needs are closed, the slit occurs between valve plate and the valve body and leak, cause potential safety hazard to production.
The utility model Swing check valve seals through outer ring O RunddichtringO between said valve gap and the valve body.
Owing to adopted said structure, can be through outer ring O RunddichtringO with sealing between valve gap and the valve body, thus can guarantee the sealing cover effect between valve gap and the valve body; When safety check during normal the use; Phenomenons such as leakage can not appear, but whole spool overall pulling down, the workload when effectively reducing field maintenance; Convenient and swift, reduce maintenance cost.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1, the utility model Swing check valve is simple in structure, and is easy and simple to handle, convenient to use;
2, the utility model Swing check valve, flow resistance is little, and does not have throttling action, and bearing capacity is big, and the life-span is permanent, and is with low cost.
