Abstract
The utility model discloses a novel antireverse valve spool; the valve spool body is in a warhead shape, a warhead generatrix is a parabola, and a head is a cone with a coneangle of Alpha, tail part uses an arc and the parabola as a smooth transition, guiding wings are evenly arranged on surface of a parabola generatrix. Compared with the prior art, reasonable design of the antireverse valve spool causes that guiding performance and antireverse effect are very good, and solves quality problems of rubber feeding and injection process due to poor antireverse effect of the valve spool, and causes that purpose of smooth feeding is achieved for the antireverse valve spool during feeding process; sealing and antireverse effect and accuracy and stability of injection measurement are ensured during injection process, and gel breaking capacity of the injection system is greatly enhanced.
Description
Technical field
The utility model relates to a kind of novel non-return spool in a kind of valve part, the especially check valve.
Background technique
Check valve is called one-way valve again, and it only in the use in particular cases of single-way switch, only allows one-directional fluid flow, and during the fluid forward flow, valve is opened automatically, and as reverse fluid flow, valve cuts out automatically.Non-return spool is the vital part in the check valve, and the precision-fit of itself and valve gap is to guarantee special mechanical seal requirement, reaches the non-return effect of design, is the important assurance that improves the accuracy and the stability of injection measurement.Especially the injection of rubber mass, its sizing material fluid Brinell hardness is up to 90 °, more require charging and injection to reach higher irreversible process, fill process opening of valves, injection process valve are closed, and require non-return effective, existing check valve has reduced the accuracy and the stability of injection measurement owing to the structural design of non-return spool owes rationally to cause non-return weak effect.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and provides a kind of effect reasonable in design, non-return a kind of preferably novel non-return spool.
According to the foregoing invention purpose, the utility model solves by following technical proposals: a kind of novel non-return spool, it is characterized in that this spool body is bullet-shaped, the bullet bus is a parabola, head is that cone angle is the cone of α, afterbody is with circular arc and parabola smooth transition, and parabola bus surface is provided with uniform guide vane.
Described cone cone angle=120 ° ± 1 °.
Described guide vane is provided with 4～5.
Compared with prior art, non-return spool of the present utility model is designed to bullet-shaped, the selection of cone angle size and the appropriate design of guide vane, by facts have proved, its steering capability and non-return effect all are good, solve the quality problems of being brought because of the non-return function difference of spool in rubber charging, the injection process, improved the accuracy and the stability of injection measurement, and strengthened the broken glue ability of injecting systems greatly.

Fig. 2 is the left view of Fig. 1.
Fig. 3 is the utility model feed state figure.
Fig. 4 is the utility model inject state figure.
Embodiment
Below according to above-mentioned accompanying drawing the utility model embodiment is specifically described again.
A kind of novel non-return spool, shown in Fig. 1～2, this spool 1 selects 45 for use
#Steel becomes to be bullet shaped spool body with cured mould precision casting, promptly approximate high speed intermediate range missile form, bullet bus 2 is a parabola, head is the cone 4 of cone angle=120 °, afterbody is with circular arc and parabola smooth transition, uniform 4 guide vanes 3 in parabola bus surface, the advantage of 4 guide vanes of selection is stressed even, stationarity is better.Blank is through quenching with Subsequent tempering HRc30～35, and then through heat-treatment quenching HRc55, at last conical surface 4 carried out the handicraft polishing and reach precision and degree of finish requirement.Uniform guide vane 3 makes the injection transmission thrust of passing through afterbody in injection process, make head conical surface and valve gap 6 precision-fit, thereby not only guaranteed the non-return effect of the special mechanical seal of non-return spool, and the big more sealing effect of injection force is remarkable more, guaranteed the accuracy and the stability of injection measurement simultaneously, strengthened injecting systems greatly the broken glue ability of sizing material hardness up to 90 degree.
Working principle of the present utility model is shown in Fig. 3～4, in fill process, 4 uniform guide vanes 3 that rubber mass can promote on the spool 1 retreat, and rubber mass can enter storage chamber from the gap of guide vane, and withstand shoulder face in the valve seat 5, thereby make non-return spool reach steady charging purpose.In injection process, rubber mass can promote non-return spool and advance, and the nose circle conical surface 4 of spool 1 withstands valve gap 6 conical surfaces and reaches the purpose of sealing.
Claims (3)
1, a kind of novel non-return spool, it is characterized in that this spool (1) body is bullet-shaped, bullet bus (2) is a parabola, and head is that cone angle is the cone (4) of α, afterbody is with circular arc and parabola smooth transition, and parabola bus surface is provided with uniform guide vane (3).
2,, it is characterized in that described cone (4) cone angle=120 ° ± 1 ° according to the described a kind of novel non-return spool of claim 1.
