Abstract
The utility model discloses a novel type dual-port exhaust valve which comprises a valve body sealing face (1), a valve clack (2), a valve rod nut (3) and a valve rod (4), wherein the valve clack is integrated, the tail end of the valve rod is provided with the valve rod nut in a matched mode, and one end of the valve rod nut is embedded in the integrated valve clack. The novel type dual-port exhaust valve has the advantages that the valve clack is of an integrated structure, in this way, the number of parts is small in the process of assembling the exhaust valve, the exhaust valve is convenient to assemble, and time and labor are saved; in addition, the valve body sealing face is formed in a cast mode and does not need to be machined again; moreover, the overall torque of the exhaust valve is small, and the sealing effect of the exhaust valve is good.
Description
Technical field
The utility model relates to outlet valve, relates in particular to a kind of new-type double-opening exhaust valve.
Background technique
Double-opening exhaust valve is applicable on pipeline that industrial media is water, as the equipment of quick eliminating gas in pipelines, to improve efficiency and the unlikely deformation fracture of protection pipeline of carrying wetting system, is the equipment of the indispensability of pipeline.Double-opening exhaust valve is installed in outlet port, pump Pu or delivery water pipeline, in order to the air of the ducted assembly of a large amount of eliminatings, to promote water pipe and suction engine utilization efficiency, and interior once occur negative pressure with pipe, this valve is air amount rapidly, to take care of line because of damage that negative pressure is produced.
All the time, double-opening exhaust valve is as one of important valve on pipeline, and its valve flap structure is complicated, at least by three parts, is combined.
The shortcoming of above-mentioned flap is: during assembling valve, accessory is many, labor intensive, and sealing effect is not good, need to could seal compared with high pulling torque, so valve products cost is high, and working life is low.
Model utility content
The technical problems to be solved in the utility model is that existing double-opening exhaust valve valve flap structure is complicated, at least by three parts, combined, labor intensive, and sealing effect is not good, need to could seal compared with high pulling torque, the new-type double-opening exhaust valve that a kind of accessory simple in structure is few is provided for this reason.
The technical solution of the utility model is: a kind of new-type double-opening exhaust valve, it comprises valve body sealing surface, flap, Stem Mut and valve rod, described flap is whole flap, and described valve stem end adaptation has Stem Mut, and one end of described Stem Mut is entrenched on described whole flap.
The casting of valve body sealing surface described in such scheme.
Valve body sealing surface described in such scheme is curved surface, when its crooked radian makes it contact with flap, fits completely.
The beneficial effects of the utility model are that flap is overall structure, and when assembling product, part is few easy to assembly time saving and energy saving like this, and this valve body sealing surface casting, does not need machining more in addition, and the whole moment of torsion of product is little, and sealing effect is good.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
In figure, 1, valve body sealing surface, 2, flap, 3, Stem Mut, 4, valve rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises valve body sealing surface 1, flap 2, Stem Mut 3 and valve rod 4, and described flap is whole flap, and described valve stem end adaptation has Stem Mut, and one end of described Stem Mut is entrenched on described whole flap.
Whole flap, comprises flap iron core, flap encapsulate and flap guiding groove, and flap iron core is put into encapsulation die, forms whole flap after whole encapsulate, and whole flap has flap guiding groove outward.
Concrete, valve rod is provided with outside thread, Stem Mut is provided with internal thread, Stem Mut passes through the fit engagement of internal and external threads on valve rod, during use, by rotary valve rod, drive Stem Mut to move up and down, Stem Mut embeds whole flap while installing, so drive whole flap to move up and down by rotary valve rod, thereby separated with valve body sealing surface or overlap to reach and open or the object of throttle down.
Valve body sealing surface, by casting, does not need machining again, and the whole moment of torsion of product is little, and sealing effect is good, and valve body sealing surface is curved surface preferably, and when it contacts with flap, laminating completely each other, reaches reliable sealing.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (3)
1. a new-type double-opening exhaust valve, it comprises valve body sealing surface (1), flap (2), Stem Mut (3) and valve rod (4), it is characterized in that described flap is whole flap, described valve stem end adaptation has Stem Mut, and one end of described Stem Mut is entrenched on described whole flap.
2. a kind of new-type double-opening exhaust valve as claimed in claim 1, is characterized in that described valve body sealing surface casting.
3. a kind of new-type double-opening exhaust valve as claimed in claim 2, is characterized in that described valve body sealing surface is curved surface, when its crooked radian makes it contact with flap, fits completely.
