Description
Technical field
The utility model relates to a kind of mechanical part, is specifically related to a kind of seal arrangement of spile type unloading valve.
Background technique
The extensive use in the material conveying process of industries such as electric power, metallurgy, coal, chemical industry, cement of spile type unloading valve because the imperfection of seal arrangement in the conventional construction causes the leakage of medium, causes environmental pollution.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of seal arrangement of effective, durable spile type unloading valve is provided.
The technical solution of the utility model is: a kind of seal arrangement of spile type unloading valve, comprise upper valve body, press strip, inside casing, rubber plate, following valve body, valve plate, the interior skin one of pressing, the interior skin two of pressing, inner clip plate and pressing plate, described valve plate is arranged between upper valve body and the following valve body, upper valve body is provided with rubber plate with following valve body top gap location, rubber plate and upper valve body and following valve body fit, be provided with inside casing above the rubber plate, be provided with press strip above the inside casing, upper valve body is pressed skin one and interior pressure skin two in being provided with following valve body lower end, interior skin one and the interior pressure skin two of pressing fits with upper valve body and following valve body, be provided with inner clip plate above the interior pressure skin two, be provided with pressing plate above the inner clip plate.
Spile type unloading valve medium in the course of the work is a fine particle, general structure is difficult to seal up fully leaking of fine particle, the leakage part of medium is to leak with the twitch of plate (being valve plate), therefore sealing is also arranged around plate, the utility model pastes the effect lower seal that is incorporated in self weight of pipeline at the periphery of plate with rubber plate and upper and lower valve body, when the pumpback, we block with two seals at plate; First road is sealed into the relatively hard materials polytetrafluoroethylene, second road is sealed into than soft material rubber.
The beneficial effects of the utility model are: 1, can seal up fine particle in the pipeline effectively, reliably; 2, simple in structure, can regulate because of the wearing and tearing of sealing material.
