Abstract
The utility model discloses an open formula dual -purpose check valve for sleeping in immediately soon, include: the fashioned valve body of integrative casting, with valve body fixed connection's pivot, with the rotatory complex rocker of pivot, fixed mounting is in valve clack on the rocker. The utility model discloses in through with the integrative casting shaping of valve body to use soft sealing, the dual -purpose time valve that crouch is immediately ended to the feasible formula that opens soon, has the valve body of reduction and leak and good sealed effect, and the characteristic that the noise hangs down. In addition the utility model provides an open formula dual -purpose check valve for sleeping in immediately soon possesses function vertical, horizontal check valve simultaneously.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of rotary-open type horizontal-vertical double-purpose safety check.
Background technique
Swing check valve is a kind of conventional valve class device, and its principle relies on the strength of media flow to realize opening and closing, to prevent the refluence of medium.All with a valve gap in the middle part of valve body in current Swing check valve, valve gap and valve body connection part adopt gasket seal and seal ring usually, and the valve body of such Swing check valve medium by time may leak.And valve seat and flap are rigid sealing, when valve seat and valve flap contacts, very large noise can be produced.Current horizontal-vertical double-purpose non-return, media flow resistance is large, and flow is little.
Model utility content
In view of this, the utility model provides a kind of rotary-open type horizontal-vertical double-purpose safety check, this rotary-open type horizontal-vertical double-purpose safety check solves that current Swing check valve sealing is poor, noise is large, and valve body easily occurs that leak of liquid, flow resistance are large, the technical problem that flow is little.
The technical solution of the utility model is achieved in that
A kind of rotary-open type horizontal-vertical double-purpose safety check, comprising:
The valve body that integrally casting is shaping;
The rotating shaft be fixedly connected with described valve body;
With the rocking bar of described rotating shaft rotatable engagement;
Be fixedly mounted on the flap on described rocking bar.
Preferably, described flap is provided with the first sealing substance.
Preferably, described first sealing substance is specific rubber.
Preferably, described specific rubber is fluorine rubber, silicone rubber, acrylate rubber, urethane rubber, polyether rubber, haloflex, chlorosulfonated polyethylene, epoxy propane rubber, Thiokol or teflon.
Preferably, also comprise the valve seat matched with described flap, described valve seat is arranged on influent side passway.
Preferably, described valve seat is provided with the second sealing substance, and described first sealing substance is conflicted with described second sealing substance and is connected.
Preferably, described rocking bar is connected by nut or steel pin with described flap.
Preferably, described valve inner is coated with wear-and corrosion-resistant material.
The beneficial effects of the utility model are:
Pass through valve body casting in the utility model, and use soft sealing, make rotary-open type stop horizontal-vertical double-purpose and return valve, there is minimizing valve body and leak and good sealing effect, and the characteristic that noise is low.The rotary-open type horizontal-vertical double-purpose safety check that theres is provided of the utility model, possesses function that is vertical, horizontal check valve simultaneously in addition.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model rotary-open type horizontal-vertical double-purpose safety check;
In figure:
