Abstract
The utility model relates to a stop valve of a sylphon bellowss and belongs to the technical field of a valve. The prior stop valve, which is used for controlling the flowing of pipeline media in the petrochemical industry, tends to experience an external leakage after a period of time, a new valve has to be substituted and a normal operation is thus affected; especially when the external leakage occurs in the course of toxic and inflammable media transportation, future trouble is endless. A sylphon bellowss module is arranged on the valve rod in the inner cavity of the stop valve of the sylphon bellowss to seal the valve rod to prevent the medium inside the valve body from leaking outward from the feeding section on the upside of the valve rod. For prolonging the service life of the valve, the sylphon bellowss module adopts stainless steel material. By adopting the technical proposal, the utility model has the advantages of excellent sealing capacity, long service life, safety and reliability.
Description
(1) technical field
The utility model relates to valve technology field, particularly a kind of bellows stop valve.
(2) background technique
At present, be used for the stop valve that the pilot line medium circulates in industries such as oil, chemical industry, external leakage appears in use a period of time big city, must in time more renew valve, and influence is operation normally.Particularly when carrying medium such as harmful, poisonous, inflammable, the generation external leakage will have endless trouble.The bellows stop valve that the utility model aims to provide a kind of long service life, do not leak.
(3) summary of the invention
It is short that technical problem to be solved in the utility model is exactly existing stop valve external leakage and working life.For this reason, the utility model is provided with bellows component and is used for sealed valve stem on the valve rod of body cavity, makes the medium in the valve body can not be from the filler external leakage on valve rod top.For increasing this valve working life, bellows component adopts stainless steel.Owing to take above-mentioned solution, the utlity model has good seal performance, long service life, advantage such as safe and reliable.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing, optimal way of the present utility model is described further.Referring to Fig. 1 as can be known, the utility model mainly is made of parts such as valve body 1, valve gap 2, flap 3, valve rod 4, filler 5, bellows component 6 and handwheels 7.Valve gap 2 is installed on the valve body 1, flap 3 be contained in valve rod 4 the lower end and with valve body 1 sealing surface contact seal.Filler 5 is contained between valve gap 2 tops and the valve rod 4.Bellows component 6 is contained on the valve rod 4 of valve body 1 inner chamber and with its sealing, and bellows component 6 adopts stainless steels.Handwheel 7 is contained in the upper end of valve rod 4.During Open valve, rotation hand wheel 7 moves upward valve rod 4, and flap 3 rises thereupon, the medium circulation.During throttle down, counterrotating handwheel 7 moves downward valve rod 4, flap 3 descend thereupon until with valve body 1 sealing surface contact seal, medium circulation ends.
Claims (2)
