Abstract
The utility model discloses a welding butterfly valve has valve body and valve rod, is equipped with the dish board in the valve body, and the dish board is fixed on the valve rod, is equipped with between the valve rod on upper portion and the valve body to be equipped with the lower liner cover between valve rod and the valve body of bush, lower part, and the lower extreme of valve body is equipped with the tail -hood, and the lower extreme of valve rod is equipped with the divided ring, still is equipped with sealed the pad between tail -hood and the valve body, seal the downside and tail -hood butt, sealed upside while and divided ring and valve rod butt of filling up that fill up. The utility model discloses the beneficial effect who has: it is in fact sealed through packing ring and dish board sealing washer between valve body and the dish board, compare the direct structure with body seals of traditional sealing washer, sealed effect is better, has avoided the damage of valve body simultaneously, and the change can after the packing ring loss. Sealed pad can seal up clearance and the clearance between valve body and the divided ring between clearance, tail -hood and the divided ring between valve body and the tail -hood simultaneously, and is sealed effectual.
Description
Technical field
This utility model relates to butterfly valve correlative technology field, is specifically related to a kind of welding butterfly valve.
Background technology
Butterfly valve is again flap valve, it it is the regulation valve of a kind of simple in construction, the butterfly valve of the on-off control that can be used for low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, a kind of valve reaching to open and close is rotated around valve shaft, valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium, acts primarily as cut-out and throttling action on pipeline.Butterfly valve is mainly made up of valve body, valve seat, valve plate, valve shaft and actuating device, and welding butterfly valve is the one in butterfly valve, and welding butterfly valve is divided into cast steel to weld butterfly valve, stainless steel welded butterfly valve, chrome-molybdenum steel welding butterfly valve.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, it is provided that the welding butterfly valve of a kind of good sealing effect.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of welding butterfly valve, there is valve body and valve rod, dish plate it is provided with in valve body, dish plate is fixed on valve rod, it is characterised in that is provided with lining between valve rod and the valve body on top, is provided with lower lining between the valve rod of bottom and valve body, the lower end of valve body is provided with tail-hood, the lower end of valve rod is provided with divided ring, is additionally provided with sealing gasket between tail-hood and valve body, and the downside of described sealing gasket abuts with tail-hood, the upside of sealing gasket abuts with divided ring and valve rod simultaneously.
Further, described upper lining be arranged over filler, filler is located between valve body and valve rod, filler is arranged over gland, described gland is bolted to connection with the upper end of valve body, gland be arranged over support, support is provided with gear, actuating device and the handle being sequentially connected with, and described gear is connected with the upper end of valve rod.
This utility model has the advantages that
Seal actually by packing ring and dish plate sealing ring between valve body and dish plate, compare traditional sealing ring directly with the structure of valve seal, sealing effectiveness is more preferable, avoids the damage of valve body simultaneously, and packing ring is changed after being lost.Sealing gasket can simultaneously gap between gap and valve body and divided ring between gap, tail-hood and divided ring between sealed valve body and tail-hood, good sealing effect.
