Abstract
The invention discloses a corrugated pipe stop valve. In the corrugated pipe stop valve, a valve rod in an inner chamber of a valve body is provided with a corrugated pipe assembly for sealing the valve rod, so that a medium in the valve body cannot be leaked from a filler position on an upper part of the valve rod. In order to prolong the service life of the valve, the corrugated pipe assembly is made of stainless steel. By using the solution, the corrugated pipe stop valve has the advantages of high sealing property, long service life, safety, reliability and the like.
Description
One, technical field:
The present invention relates to valve technology field, particularly a kind of bellows stop valve.
Two, 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 present invention aims to provide a kind of long service life, do not leak.
Three, summary of the invention:
It is short that technical problem to be solved by this invention is exactly existing stop valve external leakage and working life.For this reason, the present invention 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 present invention to have good seal performance, long service life, advantage such as safe and reliable.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention.
Five, embodiment
Below in conjunction with accompanying drawing, the optimal way of inventing is described further.Referring to Fig. 1 as can be known, the present invention 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 in the lower end of valve rod 4 and with valve body 1 sealing surface contact seal.Filler 5 is contained between 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.When opening an account 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.
