Definitions
- the valve gate of the present disclosure is to overcome at least some of the abovementioned drawbacks and especially to provide a valve with better sliding properties and proteted against corrosion .
- the referred guide comprising an external face and an internal face with ribs that maintains a space between the guide and guide structure to be filled during the core coating process with a first polymer material, preferable a vulcanized rubber, these ribs are protrusions in the internal face, furthermore the guides has a rim in their ends that accompanies the curvature of the iron core which is covered and blocked by the rubber coating helping the fixation of the guide with the guide structure member.
- This fixation of the rim and the first polymer material that fills the interior of the guide ensures a strong fixation prevent the deformation and the detachment of the guide.
- the external face is smooth to facility de sliding of the wedge.
- the material of the core is cast iron which may undergo oxidation when exposed. Therefore, a vulcanized rubber coating is provided to protect the core against the corrosion.
- the guides comprises a U-shaped cross-section defining an internal face and an external face.
- the first polymer material is vulcanized rubber.
- Figure 1 illustrates one embodiment of a valve guide (1) that comprises a rib (1A), a rim (IB) and a cavity (1C).
- Fig.4 illustrates one embodiment of a top view of the valve gate (2) that comprises a guide (1).
- Fig. 9 illustrates the slide gate (5) and valve gate (2) thereof.

Abstract
La présente divulgation concerne des distributeurs à tiroir, en particulier un obturateur. La présente divulgation concerne un obturateur pour un distributeur à tiroir comprenant un noyau de fonte à graphite sphéroïdal (4) comportant deux saillies latérales (4A), ledit noyau étant revêtu d'un premier matériau polymère (3) et de deux guides (1) constitués d'un second matériau polymère, chacun d'eux étant monté sur une saillie latérale revêtue respective, pour coulisser dans des rainures du distributeur lorsque le distributeur coulisse entre une position ouverte et une position fermée du distributeur ; le second matériau polymère étant plus dur que le premier matériau polymère.
