Abstract
The utility model discloses a multifunction energy saving check valve, comprising a valve body. An axis is provided in the valve body, and a valve flap is hinged on the axis; a valve rod is also provided in the valve body, and the lower end of the valve rod is hinged with a connecting rod, and the other end of the connecting rod is hinged with a valve plate; the upper segment of the valve rod is connected with a two-chamber control device. The check valve is installed on a pipe network, and can replace the prior check valve and electrical control valve, and the utility model of check valve realizes the generation of a water hammer when a pump is closed, and the starting under load of the pump. Meanwhile, the valve body is a straight-way type, so almost no water can be lost in use; in addition, the connecting rod connected on the valve plate solves the problem in the prior check valve that the valve flap shakes after the check valve is opened.
Description
Technical field
The utility model belongs to the control valve on the water supply network, is specifically related to a kind of safety check.
Background technique
Be to prevent the generation of pump water hammer when closing and the starting under load of pump at present on the water supply network, the general employing at delivery side of pump connects a safety check and a motor-operated control valve, arranges that like this valve is many, connection is many, the engineering construction amount is big, has high input, and control is complicated.Existing a kind of two-chamber control multifunction valve can replace above-mentioned two valves, but this valve when using damage by water bigger, cause a large amount of energy losses.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-functional joint safety check, to overcome the defective of above-mentioned valve.
The technical solution of the utility model is: the multifunction energy-saving safety check comprises valve body, the axle of establishing in the valve body, and hinged flap on the axle is also established valve rod in the valve body, valve rod lower end articulated linkage, the other end and the valve plate of connecting rod are hinged, and the valve rod epimere is connected with the two-chamber control gear.
This safety check mounting pipe can replace safety check and motor-operated control valve on the net, realize that pump prevents the generation of water hammer and the starting under load of pump when cutting out, simultaneously because valve body is a straight-through type, substantially there is not damage by water during use, in addition, connect connecting rod on the valve plate, during water pump operation, connecting rod is opened the problem that the back flap is shaken with the flap pull-up thereby solved existing safety check.

Embodiment
As shown in Figure 1, connect connecting base 2 on the valve body 1, the two-chamber control gear is connected with connecting base 2.The two-chamber control gear comprises interconnective upper and lower covers 3,4, all offers control hole 20,21 on the upper and lower covers 3,4.Connect barrier film 5 in the upper and lower covers 3,4, form cavity of resorption 6 between barrier film 5 and the lower cover 4, form epicoele 7 between barrier film 5 and the loam cake 3.Valve rod 8 epimeres pass upper and lower covers 3,4 and sealing with it, and valve rod 8 is connected with barrier film 5.Valve rod 8 lower end articulated linkage 9, connecting rod 9 is hinged with flap 10.Coupling shaft 11 in the valve body 1, axle 11 hinged rocking bars 12, rocking bar 12 is connected with flap 10.Offer pod apertures 15,16 on valve body 1 inlet segment 13 and/or the water exit end 14.Axle 11 passes valve body 1 and sealing with it, passes coupling shaft control device for pivoting on the axle 11 of valve body 1.The axle control device for pivoting comprises and axle 11 connecting rods that are connected 17 that the other end of connecting rod 17 connects weight 18.Connecting rod 17, weight 18 are the dotted portion among the figure.The axle control device for pivoting is not limited to said structure, so long as can help flap 10 quick closedowns to get final product.
As shown in Figure 2, except that the structure of two-chamber control gear with above-mentioned different, other structures are same as described above, other structures are not repeated.The two-chamber control gear comprises the piston/cylinder 30 that is connected with connecting base 2, connects upper end cap 31 on the piston/cylinder 30, and valve rod 8 passes end cap 31,32 and sealing up and down with it; Piston/cylinder 30 hypomeres are offered pod apertures 32, offer pod apertures 34 on the upper end cap 31, establish piston 33 in the piston/cylinder 30 and are connected with valve rod 8.
The working principle of this valve is: during opening of valves, flap 10 is slowly opened under the control of the effect of hydraulic pressure and two-chamber, makes the pump on-load, and the inlet segment of opening rear valve body leads directly to water exit end; When closing, flap 10 is slowly closed under the effect of the control of two-chamber and weight.
Claims (7)
