It is bad and affect the problem of working efficiency to there is sealing effect in existing safety check, how to solve the direction that this technical problem has become the art personnel to make great efforts.
Model utility content
The utility model, in order to overcome above-mentioned technical deficiency, provides a kind of structure simple, the safety check of the Novel belt seal ring of good sealing effect.
The utility model to achieve these goals concrete by the following technical solutions:
A kind of safety check of Novel belt seal ring, comprise check valve body, check valve body comprises entrance, outlet and the spool chamber be communicated with entrance and exit, the internal thread be connected with outer tube is provided with in described entrance and exit, along described inlet shaft to setting gradually spherical valve core in described spool chamber, Returnning spring, positioning seat, described spherical valve core under described action of reset spring by described inlet seal, described spherical valve core is provided with ring-type draw-in groove, described ring-type draw-in groove is positioned on spherical valve core near inlet side, on be provided with seal ring, described positioning seat is the frustum cone structure of hollow, positioning seat is that the frustum cone structure of hollow is communicated with spool chamber and outlet.
Further, described positioning seat and check valve body interference fit.
Further, described check valve body is stainless steel structure.
Further, described seal ring is nitrile butadiene rubber seal ring.
The beneficial effects of the utility model are as follows:
Check valve seal structure of the present utility model adopts the annular slot on spherical valve core to contact with the face of seal ring coordinate and realize sealing, this fitted seal mode, sealing effect are better than mode and the effect of the contact sealing of traditional spheroidal spool, can overcome because traditional spool column cap sphere makes not rounding and to cause the contact of sphere and seal ring to seal unreliable, thus improve the reliability of product.
