Abstract
The utility model relates to a kind of lining up/down exhibition discharging valve, and comprise valve body, valve rod, flap, described valve body is provided with material feeding mouth and discharge port, and the center line of described material feeding mouth and the center line of discharge port keep certain angle; Described valve rod one end to be arranged in valve body and to connect flap, and it is outer and be connected with actuator that the other end stretches out valve body; The material feeding mouth place of described valve body is provided with Sealing, and described flap can be sealed and matched with Sealing; It is characterized in that described valve interior wall is provided with the corrosion resistant plastic materials of one deck.Its advantage is that valve body and Korrosionsmedium separate by corrosion resistant plastic materials, avoids valve to be corroded, and reduces leakage accident, improves working life.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of lining up/down exhibition discharging valve.
Background technique
Discharging valve comprises upward-expanding emptying valve and bottom open type discharging valve, be widely used in fields such as chemical industry, oil, pharmacy, agricultural chemicals, dyestuffs, common discharging valve comprises valve body, valve rod, flap, drives flap to move up and down, open or closure valve by valve rod.
But the medium circulated in existing up/down exhibition discharging valve has stronger corrosivity mostly, and in the situation that works long hours, corrosive material can slowly corrode valve body and critical piece thereof, thus causes valve to there will be leakage, and working life is low.
Model utility content
In order to overcome the deficiency of background technique, the utility model provide a kind of corrosion-resistant, long service life, lining up/down exhibition discharging valve.
The technological scheme that the utility model adopts: a kind of lining up/down exhibition discharging valve, comprise valve body, valve rod, flap, described valve body is provided with material feeding mouth and discharge port, and the center line of described material feeding mouth and the center line of discharge port keep certain angle; Described valve rod one end to be arranged in valve body and to connect flap, and it is outer and be connected with actuator that the other end stretches out valve body; The material feeding mouth place of described valve body is provided with Sealing, and described flap can be sealed and matched with Sealing; Described valve interior wall is provided with the corrosion resistant plastic materials of one deck.
Described valve rod is arranged on outside part in valve body and flap and is equipped with the corrosion resistant plastic materials of one deck.
Described corrosion resistant plastic materials is fluoroplastic material.
Described material feeding mouth is also provided with valve gap outward, and described Sealing is clipped between valve body and valve gap.
Described Sealing is seal ring, described flap with between Sealing for soft seal coordinates.
Described flap with between Sealing for conical surface seal coordinates.
Described actuator comprises support, handwheel, and the part that described valve rod is arranged on outside valve body is provided with external thread structure, and described valve rod and handwheel are connected, and with carriage center screw-thread fit.
Also be provided with one deck packing layer between described valve rod and valve body, described packing layer is by sealing gland press seal.
The beneficial effects of the utility model are: adopt above scheme, valve interior wall, valve rod, flap are equipped with the corrosion resistant plastic materials of one deck, do not react with corrosive material, avoid valve to be corroded, and reduce leakage accident, improve working life.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
1-valve body, 2-valve rod in figure, 3-flap, 4-Sealing, the corrosion resistant plastic materials of 5-, 6-valve gap, 7-support, 8-handwheel, 9-packing layer, 10-gland, 11-material feeding mouth, 12-discharge port.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further: a kind of lining up/down exhibition discharging valve, comprise valve body 1, valve rod 2, flap 3, described valve body 1 is provided with material feeding mouth 11 and discharge port 12, and the center line of described material feeding mouth 11 and the center line of discharge port 12 keep certain angle; Described valve rod 2 one end to be arranged in valve body 1 and to connect flap 3, and it is outer and be connected with actuator that the other end stretches out valve body 1; Also be provided with one deck packing layer 9 between described valve rod 2 and valve body 1, described packing layer 9 is by sealing gland 10 press seal; Material feeding mouth 11 place of described valve body 1 is provided with Sealing 4, and described flap 3 can be sealed and matched with Sealing 4; Described valve body 1 inwall is provided with the corrosion resistant plastic materials 5 of one deck, and the part that described valve rod 2 is arranged in valve body 1 is also equipped with the corrosion resistant plastic materials 5 of one deck with flap 3 is outer.
Valve body, valve rod, flap can separate with corrosive medium by this one deck corrosion resistant plastic materials completely, simultaneously itself can not with corrosive goods qualitative response, avoid valve to be corroded, not only reduce leakage accident, improve Safety performance, also improve working life simultaneously.
Wherein said corrosion resistant plastic materials 5 can be fluoroplastic, such as PTFE, ethylene, propylene etc., not only has good wear resistance, corrosion resistance, and low price, and cost is low.
Described Sealing 5 is seal ring, and described material feeding mouth 11 is outer is also provided with valve gap 6, and described Sealing 4 is clipped between valve body 1 and valve gap 6, described flap 3 with between Sealing 5 for soft seal coordinates, soft sealing structure is more prone to seal, sealing effect.
Described seal ring also can adopt PTFE material to make, and prevents Sealing from being corroded, and improves sealability, avoids revealing.
Described flap 3 with between Sealing 5 for conical surface seal coordinates, cone sealing sealing structure better effects if.
In addition, described actuator can adopt the automatic executing agencies such as pneumatic, electronic, also manual actuator can be adopted, manual actuator can be comprise support 7, handwheel 8, the part that described valve rod 2 is arranged on outside valve body 1 is provided with external thread structure, and described valve rod 2 and handwheel 8 are connected, and with support 7 center screw-thread fit, structure is simple, and easy to operate.
Embodiment should not be considered as the restriction to model utility, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
