Abstract
The utility model discloses a rubber-coating flashboard of a flexible-seat gate valve adopting the integrative rubber-coating on lead rails and a flashboard. The rubber-coating flashboard comprises a flashboard core of the flexible-seat gate valve; the lead rails are arranged inside lead rail grooves formed on two sides of the flashboard core; outer walls on two sides of each lead rail is in contact with two side walls of each lead rail groove on the flashboard core; gaps between the surface of the flashboard core and the outer bottom surfaces of the lead rails as well as between the bottoms of the lead rail grooves formed on the flashboard core and the outer bottom surfaces of the lead rails are coated with antiseptic rubber layers; and locating devices are arranged on the lead rails. When in rubber-coating, the lead rails are embedded in the lead rail grooves formed on the flashboard core first, and then the lead rails and the flashboard core are processed through vulcanization rubber-coating together. The lead rails are used for positioning during the rubber-coating process, and the manufacturing cost during the rubber-coating process is reduced. At the same time, no locating holes are formed on the flashboard core or a rubber-coating layer, thereby greatly enhancing the antiseptic ability of the cast iron flashboard core.
Description
Technical field
The utility model belongs to the gate valve parts, is specifically related to a kind of encapsulate flashboard.
Background technique
The encapsulate flashboard of elastic sluice valve with wedge-shaped sealing face is to coat one deck rubber anti-corrosive in the outside of cast iron flashboard at present, flashboard behind the encapsulate does not add guide rail mostly, though what have has installed guide rail on the encapsulate flashboard, it is earlier the flashboard wicking surface to be carried out encapsulate, has wrapped behind the glue mounting guide rail again.By add the location finger setting on the cast iron flashboard, this mode has not only increased the manufacture difficulty of encapsulate mould, and also increased processing cost during encapsulate, and flashboard encapsulate layer has a hole in the place that pin is located like this, is unfavorable for the anticorrosion of cast iron flashboard.If do not position during encapsulate, flashboard wicking surface encapsulate problem in uneven thickness then can appear.Thereby the location to the cast iron flashboard is a difficult problem always in the encapsulation process.
Summary of the invention
The purpose of this utility model is to provide the encapsulate flashboard of the elastic sluice valve with wedge-shaped sealing face of a kind of guide rail and the integrated encapsulate of flashboard, to address the above problem.
The technological scheme of technology of the present utility model is: the encapsulate flashboard of the elastic sluice valve with wedge-shaped sealing face of guide rail and the integrated encapsulate of flashboard, it comprises the flashboard core of elastic sluice valve with wedge-shaped sealing face, be provided with guide rail in the guide-track groove of flashboard core both sides, guide rail both sides outer wall contacts with flashboard core guide-track groove two side, coat the antiseptic rubber layer between the gap between flashboard wicking surface and flashboard core guide-track groove bottom surface and the guide rail outer bottom, set the position device on the guide rail.
During encapsulate, now guide rail is embedded in the guide-track groove of flashboard core, is vulcanizing encapsulate with the flashboard core then.
In encapsulation process, as the location, reduce cost of production in the encapsulation process by guide rail.Do not have positioning hole on flashboard core and the encapsulate layer simultaneously, increased the antiseptic power of cast iron flashboard core greatly.

Embodiment
As shown in Figure 2, flashboard core 1 both sides of elastic sluice valve with wedge-shaped sealing face are provided with guide-track groove 3, are provided with guide rail 2 in the guide-track groove 3, and setting the position device on the guide rail 2 is that guide rail 2 inner bottom surfaces are provided with locating slot 4, divides into two (shown in Figure 4) on the locating slot 4.Coat antiseptic rubber layer 5 between the gap between flashboard wicking surface and flashboard core guide-track groove bottom surface and the guide rail outer bottom.Guide rail 2 both sides end faces 2.1 coat 5 (as shown in Figure 3) of antiseptic rubber layers.Guide rail 2 both sides outer walls contact with flashboard core 1 guide-track groove two side.
