Abstract
The utility model discloses an installing structure for a check valve and a pipeline. The installing structure comprises a conical connecting tube and a pipeline, wherein an installing convex ring is arranged on the outer wall of the inlet end of the connecting tube, a step is arranged on the inner wall of the installing convex ring, the end part of the pipeline is provided with a clamp hoop matched with the installing convex ring, mutually sheathed gaskets are matched in the step, an internal threaded hole is annularly arranged on the installing convex ring, a locking screw bolt is screwed in the internal threaded hole, a press strip is padded and arranged between the gasket at the outer layer and the inner wall of the connecting tube, and the gaskets are pressed and placed on the outer wall of the clamp hoop. The installing structure utilizes the elasticity of the rubber per se and the reverse back pressure effect, the sealing is reliable, the seepage quantity is further reduced, or the seepage is avoided.
Description
Technical field
The utility model relates to the installation connection area of rubber Slow Close check valve, specifically belongs to the mounting structure of check valve and pipeline.
Background technique
Rubber Slow Close check valve has been widely used in various floss holes such as municipal administration, water conservancy, sewage treatment, prevents to pour in down a chimney, flow backwards, and can provide efficient; And strong work; Need not to add any energy source device, reduce operating cost, be applicable to the extraordinary operating mode of general operating mode and wearing and tearing or aggressive medium.General Purpose Rubber Slow Close check valve adopts telescopic connecting tube usually, and connection procedure is loaded down with trivial details, and join strength is not enough.
The model utility content
The purpose of the utility model provides the mounting structure of a kind of check valve and pipeline, utilizes the effect of the elasticity and the reverse back pressure of rubber itself, has realized that sealing is reliable between valve body and the pipeline, further reduces Leckage or ne-leakage.
The technological scheme of the utility model is following:
The mounting structure of check valve and pipeline includes conical connecting cylinder, pipeline, and the entrance point outer wall of described connecting cylinder has installs protruding circle; Install on the inwall of protruding circle and have step, the end of pipeline has and the clip that protruding circle matches is installed, and is combined with the packing ring of mutual sheathing in the step; Install that annular offers interior threaded hole on the protruding circle; Screwed togather lock bolt in the interior threaded hole, pad is provided with press strip between outer field packing ring and the connecting cylinder inwall, and packing ring is pressed on the outer wall of clip.
Offer the groove of bar shaped on the described connecting cylinder inwall, groove is built-in with press strip.
The utility model is elasticity and the effect of reverse back pressure that utilizes the rubber of packing ring itself, through the number of plies of adjustment packing ring, applicable to the pipeline of different size, has realized that sealing is reliable between valve body and the pipeline, further reduces Leckage or ne-leakage.
