The utility model discloses simple structure, high, the long service life of sealing performance have effectively solved the valve and be easy crystallization or easy coking scheduling problem because of the medium in the uses.
Description
Technical field
The utility model relates to ball valve technical field, particularly bellows anti-coking ball valve.
Background technique
Medium for high temperature and with solid granulates, the ball valve of current employing has generally comprised valve body, valve rod, ball core, valve pocket is provided with in described valve body, valve body is provided with flow channel, flow pass, ball core is arranged in valve pocket, valve rod one end extends in valve pocket and is linked with ball core, ball core is provided with connecting passage, ball core and flow channel, suction side valve component is respectively equipped with between flow pass, outlet side valve component, ball core is driven to rotate control connection passage and flow channel by valve rod, the conducting of flow pass, cut-off, wherein, described suction side valve component includes valve seat body, spring, sealed pressing sleeve, formed between valve seat body and ball core and firmly seal, sealing gasket is provided with between valve seat body and valve body, sealing gasket is pressed in valve seat body through sealed pressing sleeve, spring one end and sealed pressing sleeve are conflicted, the other end and valve body are conflicted, this spring is used for providing certain elastic compensating power along medium inflow direction to valve seat body, can prevent at high temperature like this, valve seat body, the parts such as sealed pressing sleeve are because of expanding with heat and contract with cold and stuck phenomenon occurs in various degree.
But, for the medium of the easy coking of some high temperature, such as high-temperature coke carburetion, easily in suction side valve component, produce coking or crystallization, valve seat body after coking, crystallization can bond together with valve body, and spring also can be stuck because of the coking of medium, cannot play the effect of elastic compensating, thus make ball core easily occur stuck phenomenon, valve cisco unity malfunction.
Model utility content
The technical problems to be solved in the utility model is to provide the bellows anti-coking ball valve that a kind of valve in use not easily produces crystallization or coking.
For achieving the above object, the technical solution of the utility model is as follows:
Bellows anti-coking ball valve, described bellows anti-coking ball valve comprises valve body, valve gap, spheroid, valve rod, valve seat, filler and stuffing box; Be provided with a seal groove between described valve seat and valve gap, be provided with bellows component in described seal groove, one end of described bellows component is connected with valve seat, and the other end is connected with valve gap; The top of described spheroid is provided with an internal thread mounting groove, and the threaded one end of described valve rod is connected in the internal thread mounting groove of spheroid; The inner side and outer side of described bellows component is equipped with steam blowing structure.
In an embodiment of the present utility model, the middle part of described valve body is provided with steam blowing structure.
In an embodiment of the present utility model, described stuffing box place is provided with steam blowing structure.
By technique scheme, the beneficial effects of the utility model are:
The utility model structure is simple, sealability is high, long service life, efficiently solves valve in use because medium is the problem such as easy crystallization or easy coking.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See shown in Fig. 1 to Fig. 4, the utility model discloses bellows anti-coking ball valve, bellows anti-coking ball valve comprises valve body 10, valve gap 20, spheroid 30, valve rod 40, valve seat 50, filler 60 and stuffing box 70; Be provided with a seal groove 80 between valve seat 50 and valve gap 20, be provided with bellows component 90 in seal groove 80, one end of bellows component 90 is connected with valve seat 50, and the other end is connected with valve gap 20; Valve seat 50 promote under the pretension effect of bellows component 90 spheroid 30 combine closely realize sealing.
The utility model is provided with an internal thread mounting groove 31 on the top of spheroid 30, and the threaded one end of valve rod 40 is connected in the internal thread mounting groove 31 of spheroid 30; Spheroid 30 and valve rod 40 adopt separate type, reduce the requirement to valve parts machining accuracy, reduce valve torque, improve sealability and valve global reliability; And reduce relative to the difficulty of processing of spheroid and valve rod integrated, reduce manufacturing procedure, valve rod and spheroid separate machined are saved time, and the spheroid of processing separately makes every size be ensured; Valve rod connects spheroid and adopts flat formula Spielpassung, and in assembly process, spheroid and valve rod are successively installed and accelerated assembling speed, flexible, convenience.
The utility model valve in use medium axially promotes spheroid and spheroid and sealing surface of seat is close to formed to seal, valve rod and spheroid connection part there is Spielpassung and spheroid without fixing, thus the Geometrical Error that effective compensation valve seat exists in course of working, valve rod not by axial medium power effect and form destruction extrusion stress, therefore filler not by the lateral compression power of valve rod thus the sealing at the valve base seal property of valve and stem packing position be improved.
Valve is in use because medium is easy crystallization or easily coking, so need to carry out high-temperature blowing 100 with steam to key position, thus corresponding site function is achieved, the utility model is equipped with steam blowing structure in the inner side and outer side of bellows component.
In order to prevent the coking of valve lumen medium to spheroid locking, be provided with steam blowing structure 100 at the middle part of valve body.
In order to prevent the coking of stuffing box medium to valve rod locking, be provided with steam blowing structure 100 at stuffing box place.
The structure of the utility model to steam blowing structure does not limit, as long as it has purge function.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
