Description
Technical field
It the utility model is related to valve technology field, more particularly to a kind of Vertical Lift Check Valves structure.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.Vertical Lift Check Valves are a kind of common check-valves, should
Kind check-valves utilizes the gravity reduction of valve element, and much using made of plastics, whole valve body and valve element are all present check-valves
Plastics, plastics have good abrasion resistance properties, and plastic poppet lighter in weight is poor using gravity reduction stability, easily leads
Fluid reflux is caused to bring potential safety hazard.
Utility model content
The utility model is in order to overcome the shortcomings of that check-valves stability is poor in the prior art, there is provided a kind of stability is good,
Vertical Lift Check Valves structure safe to use.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of Vertical Lift Check Valves structure, including valve body, the valve element that is located in valve body, upper end, the lower end of the valve body are all provided with
There is flange, valve seat is provided with the inwall of the valve body, it is characterized in that, the upper end center of the valve element is provided with guide rod, the valve
The upper end of body is provided with guide holder, is threadedly coupled between the guide holder and valve body, and the lower end of the guide holder is provided with sliding sleeve, described
Guide rod through sliding sleeve formed be slidably connected；Described guide rod and valve element are integral type structure, are set in described guide rod
There are counterweight chamber, the upper end closed of the counterweight chamber, the lower end of counterweight chamber and the lower surface of valve element are penetrated, and described counterweight intracavitary is set
There is weight linear meter.Sliding sleeve on guide holder plays guide effect to valve element, it is ensured that valve element and the stable cooperation of valve seat, may be as needed
The weight linear meter of approrpiate wts is selected, is resetted so that it is guaranteed that valve element is stablized under gravity, whole stability is good, uses peace
Entirely.
Preferably, the lower end of the valve element, which is located at around counterweight chamber, is provided with annular boss, outside the annular boss
Side is provided with end cap, and described end cap is threadedly coupled with annular boss.End cap can prevent weight linear meter from dropping out.
Preferably, described weight linear meter there are some, spring is provided between adjacent two weight linear meters.Can be as needed
The weight linear meter of varying number is selected to use spring supporting to reach counterbalancing effect between weight linear meter, prevent weight linear meter in counterweight intracavitary
Rock and influence stability；Spring can also provide pretightning force for end cap, prevent end cap from loosening.
Preferably, described guide rod is provided with stop collar, it is slidably connected between described stop collar and guide rod, institute
The side for stating stop collar is provided with locking bolt.Stop collar can limit the displacement of valve element, so as to control maximum stream flow.
Therefore, the utility model has the beneficial effect that stability is good, safe to use.
