Description
Technical field
The utility model relates to valve field, relates in particular to a kind of split direct current type metal sealing stop valve.
Background technique
In current domestic coal chemical engineering equipment, for delivery of the coal slurry valve of (comprising Heisui River, buck etc.), or Aluminum Electrolysis Production device is for delivery of the valve of slip, all adopts ball valve or integrally-built Oblique Stop Valve.Due to the non-dismountable replacing of valve seat of this type of valve, and surface sclerosis difficulty, ubiquity erosive wear resistance is poor, is prone to interior leakage and scabs the problem such as serious.When valve breaks down, need complete machine maintenance or change, impact is produced, and maintenance cost is high.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of split direct current type metal sealing stop valve is provided.
The utility model is to be achieved through the following technical solutions:
A kind of split direct current type metal sealing stop valve; comprise left valve barrel, right valve barrel, valve with changeable valve seat, protection lining, flap, valve clack cover, valve rod, valve gap, filler and actuator, left valve barrel connects right valve barrel, and valve with changeable valve seat connects protection lining; protection lining is in right valve barrel; flap is in valve with changeable valve seat, and valve clack cover connects flap, and valve rod connects valve clack cover; valve gap connects valve rod; filler connects valve rod, and actuator is in the top of stop valve, and actuator connects valve rod.
As preferably, described valve rod and flap all adopt anti-rotation type, between valve rod top and support, torsional stop are installed, and flap adopts square connection with valve rod head.
Described flap and sealing surface of seat adopt the structure of sphere to the conical surface, and valve clack sealing surface is sphere, and sealing surface of seat is the conical surface.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, high pressure resistant, erosion resistance, wear-resistant, scab proof, runner is unobstructed, be difficult for deposition material, valve seat and flap all with the equal rounding of corner medium contact, be not only conducive to surperficial cure process, and increased abrasion-resistance, in Coal Chemical Industry and aluminum electrolysis industry, be widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sealing surface schematic diagram of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is sealing surface schematic diagram of the present utility model.
A kind of split direct current type metal sealing stop valve, comprise left valve barrel 1, right valve barrel 2, valve with changeable valve seat 3, protection lining 4, flap 5, valve clack cover 6, valve rod 7, valve gap 8, filler 9 and actuator 11, left valve barrel 1 connects right valve barrel 2, valve with changeable valve seat 2 connects protection lining 4, protection lining 4 is in right valve barrel 2, flap 5 is in valve with changeable valve seat 3, valve clack cover 6 connects flap 5, valve rod 7 connects valve clack cover 6, valve gap 8 connects valve rod 7, filler 9 connects valve rod 7, actuator 11 is in the top of stop valve, actuator 11 connects valve rod 7, described valve rod 7 and flap 5 all adopt anti-rotation type, between valve rod 5 tops and support, torsional stop 10 is installed, flap 5 adopts square connection with valve rod 7 heads, described flap 5 and valve seat 3 sealing surfaces adopt the structure of sphere to the conical surface, valve clack sealing surface is sphere, sealing surface of seat is the conical surface.
Valve adopts direct current type structure, and during valve wide open, it is streamlined that passage is, and the pressure loss is little, and flow resistance coefficient is close to gate valve of the same type.Valve body adopts split-type structural (can carry out valve interior surface cure process according to the needs of operating mode), and valve seat adopts replaceable structure, and valve seat is designed with respectively special seal structure up and down.Connecting bolt by left and right valve body is locked, and has formed the sealing of left and right valve body, and valve base inner wall and flap outer surface all carry out surperficial cure process.While opening because valve is crack, velocity of medium is very fast; quite serious near the erosion in one section of region of sealing surface to right valve barrel inwall; so stud with protection lining at this position; lining inwall carries out surperficial cure process equally; strengthen the flushing resistance of easily damaged parts, improved the working life of valve integral body.During valve opening and closing, valve rod and flap are only done elevating movement, do not do rotation motion, while both having avoided stem movement and the wearing and tearing of correlated parts, avoided again flap to open and close the friction between moment sealing surface, reduced flap and opened revolution while being subject to medium impact and the valve unstability causing and the wearing and tearing that contact between component.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
