Abstract
The utility model discloses a clamp mute check-valve, comprising a valve cover, a valve flap, a pressing plate and a bolt, wherein the pressing plate is fixed on the valve flap via the bolt, the a circular hole for providing guidance for the reciprocating motion of the valve flap is arranged on the valve cover, and a soft gasket seal is provided between the valve flap and the pressing plate. With the soft gasket seal, the clamp mute check-valve is advantageous in that noises generated is lower, service lifetime for the parts thereof is longer, sealing effect of the valve is better and backflow and leakage of a medium can be avoided.
Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of wafer type DRV belongs to pump class device and plumbing equipment component technical field.
Background technique
Safety check claims one-way valve or check valve again, and its effect is to prevent that the medium in the pipeline from flowing backwards, and its application is very extensive, and especially in the application process of devices such as pump class device and plumbing equipment, safety check is indispensable especially.Existing pump class device and plumbing equipment adopt usually to the folder Lift check valve.Valve is connected to form by pressing plate and flap, and passes through bolton.Be with spring on the flap, form controlling mechanism.When medium impacts pressing plate and flap, length of spring compressed, flap passes the circular hole in the middle of the valve gap.Whole valve enters valve inner, valve open, and medium enters valve body, passes from the slit of valve edge and valve body then, and valve gap flows out.
This to the folder Lift check valve in, bolt directly carries out fastening to pressing plate and flap, the continuous punching press of medium must make bolt looseness, produces collision between valve body and the flap, vibrations, noise be generation thus also.Secondly, direct contact causes sealing poor between the metallic material.Less than normal or when stopping, the medium that flows through valve will reflux, the non-return DeGrain when the pressure of valve inlet place medium.In addition, under the punching press of medium, spring shrinks, and flap base and the collision of valve gap bottom also can produce vibrations and noise.Collision between each component has not only produced noise pollution, also causes each damage of components simultaneously, shortens the working life of safety check.
Summary of the invention
The purpose of this utility model is to provide a kind of wafer type DRV, to solve problems such as easy generation noise, poor sealing performance, component that existing safety check exists are fragile.
In order to address the above problem, the wafer type DRV that the utility model provides comprises valve gap, flap, pressing plate and bolt, described pressing plate by described bolt on described flap, described valve gap is provided with the circular hole that guiding is provided for the to-and-fro motion of described flap, wherein, be provided with soft gasket seal between described flap and the described pressing plate.
According to a kind of preferred implementation of above-mentioned wafer type DRV, wherein, the outer periphery of the side that described flap contacts with described soft gasket seal and the outer periphery of described soft gasket seal are concordant.
According to a kind of preferred implementation of above-mentioned wafer type DRV, wherein, be provided with shell fragment between the hexagon head of described bolt and the described pressing plate.
According to a kind of preferred implementation of above-mentioned wafer type DRV, wherein, the hole wall of described circular hole is provided with soft axle sleeve and directly clashes into described circular hole with the valve rod that prevents described flap.
According to a kind of preferred implementation of above-mentioned wafer type DRV, wherein, the base that described soft axle sleeve extends to prevent described flap to the outside of the lower end mouth of described circular hole directly clashes into described circular hole.
According to a kind of preferred implementation of above-mentioned wafer type DRV, wherein, described flap bottom is provided with draw-in groove, and described draw-in groove passes and block described soft gasket seal and described pressing plate.
By soft gasket seal is set, the wafer type DRV that the utility model provides can reduce the working life of generation, the elongated component of noise, the sealing effect that strengthens valve prevents medium back flow and leakage.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, the utility model preferred embodiment comprises flap 1, valve gap 2, valve body 3, bolt 5, pressing plate 6 and spring 8, pressing plate 6 is fixed in by bolt 5 on the base of flap 1, and valve gap 2 is provided with the circular hole that guiding is provided for flap 1 to-and-fro motion, and spring 8 is set in the valve stem part of flap 1.The punching press that flap 1 and pressing plate 6 are subjected to such as media such as flowing water, spring 8 compressions, the valve rod of flap 1 passes the circular hole on the valve gap 2, valve open, MEDIA FLOW mistake.In order to increase the tightness between flap 1 and the pressing plate 6, prevent that bolt 5 is loosening, reduce noise, in this preferred embodiment, be provided with soft gasket seal 7 between flap 1 and the pressing plate 6.It is loosening that the application of soft gasket seal 7 not only makes bolt 5 be difficult for, being connected of flap 1 and pressing plate 6 is more fastening, and can increase the sealing effect of valve, less than normal or when cutting off the water when valve water inlet place hydraulic pressure, owing to set up soft gasket seal 7, sealing between valve and the valve body 3 is very rigorous, and the water that flows through valve can't be refluxed.
Prevent the component rigid collision, significantly reduce the effect of noise in order further to strengthen this preferred embodiment, in this preferred embodiment, the circular hole hole wall of valve gap 2 is provided with soft axle sleeve 9, and soft axle sleeve 9 extends to the lower end mouth outside of circular hole, soft like this axle sleeve both can prevent the valve stem part bump circular hole of flap 1, can also prevent the bottom of the base portion bump circular hole of flap 1, eliminate vibrations and noise, realize quiet and elongated component working life, soft axle sleeve 9 can be made by nylon material.
In order to make the beneficial effect maximization of soft gasket seal 7, and do not increase process complexity, as shown in Figure 1, in this preferred embodiment, soft gasket seal 7 is an annular, and flap 1 is concordant with the outer periphery of soft gasket seal 7 with the outer periphery of the side that soft gasket seal 7 contacts.
In order to increase the fastening effect of 5 pairs of flaps 1 of bolt, pressing plate 6, be provided with shell fragment 4 between the nut of bolt 5 and the pressing plate 6; In addition, flap 1 bottom is provided with a draw-in groove 10, and draw-in groove 10 passes and block soft gasket seal 7 and pressing plate 6.
In the application process of this preferred embodiment, when flowing water punching press valve, spring 8 sheathed on the flap 1 of valve is compressed, and the guide rod of flap 1 partly passes the circular hole at valve gap 2 centers, makes whole valve enter valve body 3, valve opening.Flowing water enters valve body 3, and evenly passes from the valve body 3 and the slit at valve edge, flows out from valve gap 2 again, and current are even, smooth, resistance is little.Less than normal or when cutting off the water, spring is stretched for 8 times when valve water inlet place hydraulic pressure, make valve closing, because valve adds last layer gasket seal 7, make tight that whole valve and valve body 3 seal, the water that flows through valve can't be refluxed, play the effect of non-return.
In sum, the utlity model has multiple anticollision measure, can prevent the rigid collision between the component, almost can abate the noise, prolong the working life of product, save the utility model user's maintenance cost.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
