Abstract
The invention provides an exhaust valve which comprises an exhaust valve cover. The exhaust valve cover is provided with a plurality of transparent observation windows which are provided with transparent glass, the exhaust valve cover is connected with a flange through a plurality of supporting columns, a plurality of bolts are arranged on the flange, and a lifting ring is arranged at the top of the exhaust valve cover. The exhaust valve has the advantages that a hood device of the exhaust valve is provided with an internal anticorrosion protection layer, and therefore the service life of the exhaust valve can be greatly prolonged; through the arrangement of the transparent observation windows, the working state of the exhaust valve can be observed in the use process, and therefore unusual conditions can be observed and checked in time conveniently.
Description
Technical field
The invention belongs to valve arrangement manufacturing technology field, especially relate to a kind of outlet valve.
Background technique
Rapid escape valve is applicable on pipeline that working medium is water, to improve efficiency and the unlikely deformation fracture of protection pipeline of carrying wetting system, is the equipment of the indispensability of pipeline.Rapid escape valve is for pressure, to carry the exhaust of waterpipe, has following characteristics: can get rid of ducted gas, support resistance, energy saving.Venting capacity is many times of common double-opening exhaust valve.When pipe negative pressure, this product can be fast automatic air-breathing, prevents pipeline breaking.Cover body internal surface at rapid escape valve often gets rusty because of hot steam corrosion, thereby cause the whole breakage of outlet valve to be scrapped, cause larger waste, simultaneously, because exhaust nozzle is located at cover body inside, the exhaust situation of outlet valve is difficult to observe, therefore, there is defect in the cover body parts of existing outlet valve, requires further improvement and perfect.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of top hat device that can observe exhaust gas inside situation, is particularly suitable for the application of rapid escape valve in the pipelines such as water route.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of outlet valve, comprise outlet valve cover body, wherein, described outlet valve cover body is provided with many cover transparent windows, and described viewing window is provided with clear glass, and described outlet valve cover body is connected with flange plate by many supporting posts, described flange plate is provided with many bolts, and described outlet valve cover body top is provided with and lifts ring body.
Further, described supporting post has 3-6 bar.
Further, described bolt has 4-8 root.
Further, described viewing window is provided with transparent convex lens.
Further, described outlet valve cover body inside is provided with corrosion protective covering.
Advantage and good effect that the present invention has are: the top hat device of this outlet valve is provided with inner corrosion protective covering; the working life that can have very big raising rapid escape valve; by transparent windows is set; can in use observe the working state of exhaust nozzle, be conducive to observe in time unusual condition and investigate in time.
