Description
Technical field
The utility model relates to modulating valve technical field, especially a kind of safety check that is applicable to water, oil and some corrosive liquids.
Background technique
Safety check refers to and relies on medium itself to flow or spring pressure and open and close flap automatically, is used for preventing the valve of medium refluence, claims again one-way valve.Safety check belongs to a kind of automatic valve, on the pipeline of its Main Function medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.Traditional check valve structure complexity, assembles loaded down with trivial detailsly, and working life is short, moves not steadily, and noise is large, and poor sealing performance easily causes to leak to cause occurring security incident.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, noise is little, the rolling-ball non-return valve of good seal performance.
The utility model solves the technological scheme that its technical problem adopts: a kind of rolling-ball non-return valve, there is valve body and valve gap that stainless steel makes, be arranged on the spin in valve body, and liquid inflow entrance and liquid flowing outlet, described liquid inflow entrance and liquid flowing outlet arrange in the same way, the position that described valve body and valve gap contact is provided with seal ring, valve body and valve gap outer wall are provided with puigging, and valve body is provided with groove near one end of liquid flowing outlet.In order to improve the sealability of rolling-ball non-return valve, seal ring material is teflon.
Further, described valve gap is fixedly connected on valve body by nut or buckle.
Further, described puigging is the Sound-proof material that the stacked thermo-compression bonding of polyester fibre forms.
Further, described valve body two ends are provided with flange.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, be provided with seal ring at valve body and valve gap connecting part, valve body and valve gap outer wall are provided with puigging, have stable and reliable for performance, wear-resistant, long service life, operate steadily, the advantage such as friction, noise free.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. valve body, 2. valve gap, 3. seal ring, 4. puigging, 5. spin, 6. nut, 7. liquid flowing outlet, 8. liquid inflow entrance, 9. groove.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Rolling-ball non-return valve as shown in Figure 1, there is valve body 1 and valve gap 2 that stainless steel is made, be arranged on the spin 5 in valve body 1, and liquid inflow entrance 8 and liquid flowing outlet 7, liquid inflow entrance 8 and liquid flowing outlet 7 arrange in the same way, the position that valve body 1 and valve gap 2 contact is provided with seal ring 3, and valve body 1 and valve gap 2 outer walls are provided with puigging 4, and valve body 1 is provided with groove 9 near one end of liquid flowing outlet 7; Valve gap 2 is fixedly connected on valve body 1 by nut 6.Valve body 1 two ends are provided with flange.
When work, liquid enters valve body 1 from liquid inflow entrance 8, promotes spin 5 to valve gap 2 places motion, and liquid is from spin 5 gap, below trickle outflow openings 7; In the time that liquid stops flowing, under Action of Gravity Field, spin 5 is parked in groove 9 places, prevents that liquid from pouring in down a chimney from liquid flowing outlet 7, thereby realizes one-way flow.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
