Abstract
A corrugated pipe discharge valve with a corrugated pipe protecting sleeve comprises a pressing plate, a packing component, a valve cover, a valve body, a pressing sleeve, a corrugated pipe, a valve rod, the corrugated pipe protecting sleeve, a connecting sleeve and a valve element. The connecting sleeve end of the corrugated pipe component is welded to one end of the valve rod. The pressing sleeve end of the corrugated pipe component is clamped between the valve cover and the valve body, and sealing gaskets are arranged at the connecting position of the pressing sleeve and the valve body and the connecting position of the pressing sleeve and the valve cover respectively. According to the arranged corrugated pipe protecting sleeve, the situation that the service life of a corrugated pipe is shortened due to the fact that media flow and flush the corrugated pipe is avoided, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of bellows discharging valve, relates in particular to a kind of bellows discharging valve that bellows protecting jacket is housed.
Background technique
Bellows discharging valve, valve gap adopts corrugated tube sealing structure, and Bellows valves can thoroughly be eliminated the possibility of processing medium from stem movement gap to external leakage.Due to the deformability of bellows element itself and remarkable ageing resistance, this discharging valve has overcome the weakness such as filler aging and temperature sensitivity that packing sealing valve exists conventionally completely.Secondly, adopt bellows and filler double sealing structure, safety reliability is better.It is mainly used in the operating mode of the medium of some severe toxicity, severe corrosive, permeability, radioactivity etc.Traditional its bellows of bellows discharging valve is placed in valve flowing channel chamber, and bellows is subject to directly washing away of flowing medium, and bellows is easy to damage, and the life-span reduces.
In the prior art, application number is 200710085380.3, denomination of invention is a kind of for the discharging valve on chemical plant installations, it is characterized in that: in valve body inner bore, establish flap, valve seat, valve base, wherein, valve seat adopts interference or bonding mode to be fixed in valve body, other part is Spielpassung, the plane that above-mentioned part contacted each other all forms the sealing surface of valve, the T shape hole of T oblique crank Z connection valve base bottom, through valve seat, axle sleeve, axle sleeve bottom connects the T-slot of flap, and be connected with T oblique crank Z with key, belleville spring is by T oblique crank Z, be placed in axle sleeve, on the upper and lower end face of nut, with the screw thread capable of regulating valve seat on nut and T oblique crank Z top, the seal pressure of valve base.Clockwise and rotate counterclockwise handle and drive valve base, flap to do 90 ° of rotations together with can be simultaneously, make on flap, valve seat, valve base, there is the runner hole connection of same shape or block, just can open and close easily valve.Have that switch is rapid, operational torque is little, save material, use and the advantage such as easy to maintenance, the life-span is grown.But this invention is not also suitable for corrosive medium.
In the prior art, separately have that application number is 201210336797.3, this disclosure of the invention a kind of discharging valve, in valve body, by bottom protrusion one bearing support block, in the middle of this bearing support block, is provided with pilot hole, a composite bearing is arranged in this pilot hole; With this pilot hole concentric, radius is greater than pilot hole and is provided with a groove, with the lower end of an accommodating Returnning spring, and this Returnning spring the other end and a spool bottom connection, and this Returnning spring is sheathed on and runs through the opening outside valve follower of spool middle part perforate, and one end and the composite bearing of opening valve follower connect; One valve seat is located at the opening of valve body, makes seal spool in valve body, and opens valve follower and run through this valve seat.The invention has the advantages that: volume is little, lightweight, safe and reliable, with low cost; Valve is taked out valve top-opening type structure, has removed operator's manual operation from; Spool and the soft-hard sealing structure of valve seat composition, make sealing more reliable, can accomplish, without leaking, to reach the requirement of environmental protection.But the described discharging valve complex structure of this invention, meets Korrosionsmedium, will corrode the internal structure member of discharging valve.
Model utility content
Be subject to washing away of flowing medium for fear of the bellows of bellows discharging valve, the utility model provides a kind of bellows discharging valve that bellows protecting jacket structure is housed.
A kind of bellows discharging valve that bellows protecting jacket is housed of the present utility model is made up of pressing plate, filler member, valve gap, sealing, valve, gland, bellows, valve rod, bellows protecting jacket, connecting sleeve, spool, pin.
Described pressing plate is provided with filler member; described pressing plate is fixed by bolt and valve gap; the joint of gland and valve body, valve gap is respectively equipped with sealing gasket; between valve gap and valve body, be bolted to connection; in the middle of described valve gap and valve body are clamped in gland one end; in described valve body, set gradually from inside to outside valve rod, bellows, bellows protecting jacket, connecting sleeve; one end of described bellows protecting jacket is welded on the spool in connecting sleeve; spool is connected with valve rod by the screw thread on valve rod, and uses pin to be fixed.
A kind of bellows discharging valve that bellows protecting jacket is housed described in the utility model; its superior effect is: in the time of valve opening; medium flows into, flows out from lower end mouth from the upper end-hole of described discharging valve; flowing medium directly contacts with bellows protecting jacket; avoid flowing medium to the washing away of bellows, extended the working life of bellows.
