Description

A kind of horizontal lift check valve

Technical field

The utility model relates to a kind of fluid control valve, particularly a kind of horizontal lift check 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 Lift check valve mainly comprises valve body, valve gap, flap and valve rod, water intake that said valve body is provided with vertically and water outlet; Said valve body is provided with valve seat between water intake and water outlet, have the valve port that connects medium fluid on the said valve seat, and said valve gap is located at the top of the above valve seat of valve body; But on the valve port of being located at valve seat of said flap through the pressure folding of medium fluid, said bonnet lower is provided with guide holder, and an end of said valve rod is telescopic to be located in the guide holder of valve gap; The other end is fixedly connected with flap, when the pressure of water intake during greater than the pressure of water outlet, washes flap open thereby pressure medium can make valve rod move upward; Pass through smoothly, when the pressure of water outlet during greater than the pressure of water intake, flap is closed under the effect of refluence medium and deadweight; Its sealing surface and sealing surface of seat closely cooperate, and play the effect that stops flowing medium to flow backwards, still; Existing Lift check valve is processed for the general cast iron metallic material that adopts that reduces production costs; Generally do not have a decay resistance, when in the medium fluid of corrosive action, using, can influence the overall performance and the working life of Lift check valve.

The model utility content

To the problems referred to above, the utility model propose a kind of novel structure, using scope wide, can carry out real-time regulated, easy to operate, long service life, horizontal lift check valve that Corrosion Protection is good according to rate-of flow.

For solving this technical problem; The utility model is taked following scheme: a kind of horizontal lift check valve, comprise valve body, valve gap, flap and valve rod, and said valve body is provided with water intake and water outlet vertically; Said valve body is provided with valve seat between water intake and water outlet; Have the valve port that connects medium fluid on the said valve seat, said valve gap is located at the top of the above valve seat of valve body, but on the valve port of being located at valve seat of said flap through the pressure folding of medium fluid; Said bonnet lower is provided with guide holder; One end of said valve rod is telescopic to be located in the guide holder of valve gap, and the other end is fixedly connected with flap, and the outer side wall of the madial wall of said valve body and valve gap and guide holder and valve rod and flap applies one deck preserving timber bed of material respectively.

Further improvedly be: the said preserving timber bed of material is polytetrafluorethylecoatings coatings or epoxy coating.

Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: the horizontal Lift check valve of the utility model applies one deck preserving timber bed of material respectively at the madial wall of valve body and valve gap and guide holder and the outer side wall of valve rod and flap; The preserving timber bed of material can be with the media isolated of valve body, valve rod, flap, valve gap and guide holder and the valve body of flowing through, and can protect valve body, valve rod, flap, valve gap and guide holder main body not to receive the corrosion of medium, has enlarged the using scope of safety check; Prolonged the working life of safety check, its novel structure, using scope is wide; Can carry out real-time regulated according to rate-of flow; Easy to operate, long service life, Corrosion Protection is good.

Description of drawings

Fig. 1 is the utility model example structure schematic representation.

Embodiment

Combine accompanying drawing and specific embodiment that the utility model is further specified at present.

With reference to figure 1; Present embodiment discloses a kind of horizontal lift check valve; Comprise valve body 1, valve gap 2, flap 3 and valve rod 4, said valve body 1 is provided with water intake 11 and water outlet 12 vertically, and said valve body 1 is provided with valve seat 13 between water intake 11 and water outlet 12; Have the valve port 131 that connects medium fluid on the said valve seat 13; Said valve gap 2 is located at the top of valve body 1 the above valve seat 13, but on the valve port of being located at valve seat 13 131 of said flap 3 through the pressure folding of medium fluid, said valve gap 2 bottoms are provided with guide holder 21; One end of said valve rod 4 is telescopic to be located in the guide holder 21 of valve gap 2; The other end is fixedly connected with flap 3, and said valve body 1 applies one deck preserving timber bed of material 5 respectively with the madial wall of valve gap 2 and guide holder 21 and the outer side wall of valve rod 4 and flap 3, and the said preserving timber bed of material 5 is polytetrafluorethylecoatings coatings or epoxy coating.

The horizontal Lift check valve of the utility model applies one deck preserving timber bed of material respectively at the madial wall of valve body and valve gap and guide holder and the outer side wall of valve rod and flap, and the preserving timber bed of material can be with the media isolated of valve body, valve rod, flap, valve gap and guide holder and the valve body of flowing through; Can protect valve body, valve rod, flap, valve gap and guide holder main body not to receive the corrosion of medium, enlarge the using scope of safety check, prolong the working life of safety check; Its novel structure; Using scope is wide, can carry out real-time regulated according to rate-of flow, and is easy to operate; Long service life, Corrosion Protection is good.

The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
