Description
Technical field
The utility model relates to valve technology field, particularly, relates to a kind of multi-functional valve of double seal.
Background technique
Chinese patent CN201083288U discloses a kind of one-way valve, comprise upper valve body, lower valve body, valve core case, spool, described upper valve body and lower valve body are connected to form cavity, valve core case is fixed between valve body and lower valve body, valve core case has liquid flow hole and spool bore, described spool is arranged in spool bore, described spool comprises seal face and core bar, seal face is arranged on one end of core bar, described seal face is inverted frustoconic shape, and the inwall of lower valve body is the inverted round table shape corresponding with seal face.But the one-way valve structures complexity disclosed in above-mentioned patent documentation, function singleness, sealing effect is not good.
Model utility content
The utility model, for defect of the prior art, provides a kind of multi-functional valve of double seal.
The utility model provides a kind of multi-functional valve, comprising: valve body, and in hollow structure, the upper and lower two ends of described valve body are respectively equipped with screw thread, and middle part is provided with the encapsulate layer for radiowelding; Spool, rounded structure, the diameter of described spool is greater than the aperture of the intermediate hole of described valve body; Valve gap, in concave structure, described valve gap inwall is provided with internal thread, described valve gap inside is provided with annular spool fixed base, the diameter of described spool fixed base is greater than the aperture of the intermediate hole of described valve body, and be less than the diameter of described spool, be provided with seal ring between described valve gap inwall and described spool fixed base.
Preferably, described spool is quality of rubber materials.
Preferably, described valve body is ABS material.
Preferably, described encapsulate layer is PVC material.
The utility model utilizes ABS material valve body extruded by the mould of sizing, then at valve body outer quadric injection mould PVC material encapsulate layer.By a mould secondary machine shaping, both can use as the discharging valve of pond series products, then the function of spool one-way conduction can be utilized, as the gas charging valve of inflation series products.On using, only need rotary valve cover just can reach the function of a thing dual-purpose to the upper end of valve body or lower end, decrease the cost of twice-die-opening.The utility model adopts the double sealing structure of seal ring and spool, and sealability is excellent.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
Be illustrated in figure 1 the overall structure schematic diagram of described multi-functional valve of the present utility model, Fig. 2 is sectional drawing, Fig. 3 is version sectional view, valve body 1, in hollow structure, valve body about 1 two ends are respectively equipped with screw thread, middle part is provided with the encapsulate layer 6 for radiowelding, encapsulate layer 6 is PVC material, encapsulate layer 6 by two-shot process and valve body integrated, valve body 1 is ABS material; Spool 2, rounded structure, the diameter of spool 2 is greater than the aperture of the intermediate hole of valve body 1, and spool 2 is quality of rubber materials; Valve gap 3, in concave structure, valve gap 3 inwall is provided with internal thread, valve gap 3 inside is provided with annular spool fixed base 5, the diameter of spool fixed base 5 is greater than the aperture of the intermediate hole of described valve body 1, and is less than the diameter of described spool 2, is provided with seal ring between valve gap 3 inwall and spool fixed base 5.
Fig. 4 is the structural representation of embodiment one of the present utility model, and this is embodied as a discharging valve, and encapsulate layer 6 high frequency is on pond, and valve gap 3 is positioned at spool 2 one end.During water storage, valve gap 3 is connected fastening by screw thread with valve body 1, the end face of the water outlet (upper square opening) of valve body 1 is close to by the seal ring 4 of valve gap 3, the spool fixed base 5 of valve gap 3 presses the upper surface of spool 2, make the lower surface of spool 2 be close to the intermediate hole of valve body 1, thus reach the effect of double seal.When discharging water, valve gap 3 is opened, and spool plays the effect of one-way conduction, conveniently discharges water.
Fig. 5 is the structural representation of embodiment two of the present utility model, and this embodiment is a gas charging valve, and encapsulate layer 6 high frequency is on cavity, and valve gap 3 is positioned at away from spool 2 one end.During inflation, open valve gap 3, gas enters valve body from the suction port (lower square opening) of valve body 1, by one-way conduction spool 2, thus enters cavity.Inflate complete, valve gap 3 is connected fastening by screw thread with valve body 1, the end face of the suction port (lower square opening) of valve body 1 is close to by the seal ring 4 of valve gap 3, the upper surface of spool 2 is due to the pressure of gas, make the lower surface of spool 2 be close to the intermediate hole of valve body 1, thus reach the effect of double seal.
The utility model, by a mould secondary machine shaping, both can use as the discharging valve of pond series products, then can utilize the function of spool one-way conduction, as the gas charging valve of inflation series products.On using, only need rotary valve cover just can reach the function of a thing dual-purpose to the upper end of valve body or lower end, decrease the cost of twice-die-opening.The utility model adopts the double sealing structure of seal ring and spool, and sealability is excellent.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
