Description
Technical field
The utility model relates to a kind of fluid control valve, particularly a kind of non-return valve.
Background technique
Safety check is claimed one-way valve or check valve again, and its effect is to prevent that the medium in the pipeline from flowing backwards, and is widely used in the fluid line.Existing universal Swing check valve mainly comprises valve body, valve gap, and valve gap is located at the valve body top; Said valve body part vertically is provided with the runner that connects medium, and said runner has water intake and water outlet, and the side near water intake in the said valve flowing channel is provided with discoid valve plate; The rotating shaft that this valve plate can be provided with in valve body rotates, and when the pressure of water intake during greater than the pressure of water outlet, medium can be washed valve plate open; Pass through smoothly, when the pressure of water outlet during greater than the pressure of water intake, valve plate is closed under the effect of refluence medium; Its sealing surface and valve body sealing surface closely cooperate, and play the effect that stops flowing medium to flow backwards.But existing safety check does not have the pulling force of spring when opening, when flow, variation in pressure; Valve plate often clashes into valve body, produces noise and does not say, also influences the working life of valve plate; Because medium refluence speed is fast, the speed that valve plate is closed generally lags behind the speed that medium flows backwards, and still has the part medium counter flow when valve plate is closed; Be prone to produce the phenomenon of water hammer and pneumatic hammer, in addition, existing safety check does not establish buffering when cutting out; Valve plate and valve base sealing property are bad, and the pressure of water outlet hour in valve body is prone to produce leakage phenomenon.
Summary of the invention
To the problems referred to above, the utility model proposes a kind of simple in structure, cost is low, buffering and good sealing effect can effectively prevent dielectric leakage, long service life non-return valve.
For solving this technical problem, the utility model is taked following scheme: a kind of non-return valve comprises valve body, valve gap, valve plate; Said valve gap is located at the valve body top; Said valve body part vertically is provided with the runner that connects medium, and said runner has water intake and water outlet, and the side top near water intake on the said valve body wears a rotating shaft; Said valve plate is located at the interior side near water intake of valve body; One of which end and rotating shaft articulate, and relative valve plate forms valve seat on the said valve interior wall, and it is secondary that valve plate and valve seat constitute motive sealing; The inside circumference wall of said valve seat is provided with magnetic tablet, and contacted that one side of said valve plate and valve seat is provided with and the corresponding magnetic of valve seat magnetic tablet with the corresponding position of valve seat magnetic tablet.
Further improvedly be: a plate is established in that side top near water outlet in the said valve body, is provided with spring between said connecting plate and the valve plate.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: this non-return valve, and the inside circumference wall of its valve body upper valve base is provided with magnetic tablet; Contacted that one side of said valve plate and valve seat is provided with and the corresponding magnetic of valve seat magnetic tablet with the corresponding position of valve seat magnetic tablet, and when the pressure of water outlet in the valve body during greater than the pressure of water intake, the medium of adverse current acts on valve plate; Valve plate moves downward when realizing closing, and magnetic and the magnetic tablet on the valve seat on the valve plate can attract each other, and make the valve plate quick closedown; It is unsteady to have prevented that valve plate from closing the back; It is tightr that valve plate is contacted with valve seat, and good sealing effect has effectively stoped the refluence of medium.A plate is established in that side top near water outlet in the said valve body, is provided with spring between said connecting plate and the valve plate, when spring is in quiet state valve plate is had the effect of stretching; When the pressure of water intake in the valve body during greater than the pressure of water outlet, spring can be alleviated the instantaneous pressure of water intake, has reduced valve plate the hammering of valve body is destroyed; Can play a part automatically simultaneously to regulate current, have energy-conservation effect, when the flow of fluid changes; The pressure of the telescopic variation available buffer fluid of spring has solved the noise that produces when valve plate impacts valve body, has quiet effect; When water outlet pressure during greater than water intake pressure, the spring return that is stretched, the pulling force of spring return and the pressure of adverse current act on valve plate simultaneously; Make fast downwards throttle down of valve plate, prevent the water hammer and the pneumatic hammer that produce because of adverse current, can protect the safety of pipe-line system; Simultaneously, when valve plate moved downward the limit position to the spring return, the spring of this moment returned to static pulling forcing state; The impact that the available buffer valve plate is downward, the sealing surface that valve plate is contacted with valve seat has slowed down impact, has prolonged the working life of valve plate and sealing surface of seat.
