Abstract
The invention discloses a lifting check valve which is long in service life. The lifting check valve comprises a valve body and a valve deck. The valve body and the valve deck are connected through a bolt and a nut. An inlet channel and an outlet channel are formed in the valve body. A valve seat is arranged on one side of the inlet channel in the valve body. A channel mutually communicated with the inlet channel is formed in the valve seat. A valve clack mutually matched with the valve seat is arranged in the valve body. The valve rod is connected to the upper end of the valve clack, the upper end of the valve rod is arranged in a chute inside the valve deck in a sliding mode, a spring is arranged in the chute, one end of the spring abuts against the valve deck, and the other end of the spring abuts against the valve rod. The lifting check valve has the advantages that when the lifting check valve is normally used, the non-return function is well achieved, use is more convenient, the non-return effect is good, the service life is long, and the use requirement can be well satisfied.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of Lift check valve.
Background technique
On the pipeline of the industry such as oil, chemical industry, all can use safety check, for the cut-out of liquid in pipeline, existing safety check, in use non-return weak effect, time has been grown and has easily caused non-return failure, and working life is short, can not meet well usage requirement.
Summary of the invention
Technical problem to be solved by this invention is: the Lift check valve that a kind of long service life is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: Lift check valve, comprise: valve body and valve gap, between described valve body and valve gap, be connected by screw bolt and nut, in described valve body, be provided with inlet passage and outlet passage, a side at described valve inner inlet passage is provided with valve seat, in valve seat, be provided with the passage being interconnected with inlet passage, in described valve body, be provided with the flap cooperatively interacting with valve seat, the upper end of described flap is connected with valve rod, the upper end of described valve rod is slidably arranged in the chute of valve gap inner side, in described chute, be provided with spring, one end and the valve gap of described spring offset, the other end and the valve rod of described spring offset.
Advantage of the present invention is: above-mentioned Lift check valve is arranged on pipeline, and while normally use, it can play check function well, uses conveniently, and non-return is effective, and long service life can meet usage requirement well.
Brief description of the drawings
Fig. 1 is the structural representation of Lift check valve of the present invention.
In figure: 1, valve body, 2, valve gap, 3, bolt, 4, nut, 5, inlet passage, 6, outlet passage, 7, valve seat, 8, passage, 9, flap, 10, valve rod, 11, chute, 12, spring.
Embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Lift check valve, comprise: valve body 1 and valve gap 2, between described valve body 1 and valve gap 2, be connected with nut 4 by bolt 3, in described valve body 1, be provided with inlet passage 5 and outlet passage 6, a side at the inner inlet passage 6 of described valve body 1 is provided with valve seat 7, in valve seat 7, be provided with the passage 8 being interconnected with inlet passage 5, in described valve body 1, be provided with the flap 9 cooperatively interacting with valve seat 7, the upper end of described flap 9 is connected with valve rod 10, the upper end of described valve rod 10 is slidably arranged in the chute 11 of valve gap 2 inner sides, in described chute 11, be provided with spring 12, one end of described spring 12 and valve gap 2 offset, the other end of described spring 12 and valve rod 10 offset.
When above-mentioned Lift check valve is arranged on and plays check function on pipeline, liquid medium is by inlet passage 5, passage 8 is pushed flap 9 open and is then entered outlet passage 6, in the process of passing through at fluid, flap 9 is boosted, flap 9 promotes valve rod 10 at the interior upward sliding of chute 11, the upper end Compress Spring 12 of valve rod 10, when the flow of liquid medium is constant, spring 12 keeps compressive state, flap 9 is opened, in the time not having liquid medium process or liquid medium to reflux, spring 12 automatically opens promotion valve rod 10 and moves downward until flap 9 is closed, when normally using, above-mentioned Lift check valve can play well check function.
