Description

The anti-coking ball valve
Technical field
The utility model relates to a kind of high-temperature ball valve, and particularly a kind of anti-coking ball valve, this ball valve mainly are used in the break-make control of carrying out circulation medium on residual oil pipeline at the bottom of the delayed coking unit coke drum or the coke cat head oil-gas pipeline.
Background technique
In petroleum refining industry, along with crude oil deep process technology development, oil refinery adopts delayed coking unit will refine oil residue-residual oil and processes carbonization product mostly.Usually adopt the technology mode of a stove two towers or a stove four towers in the existing delayed coking unit; To improve equipment efficient; The switching of residual oil pipeline or coke cat head oil-gas pipeline all is that control through various valves realizes at the bottom of the delayed coking unit coke drum, and its core process requires to be controlled at the time that needs through valve to be switched raw material and be transported to one of them coke drum, because residual oil viscosity is big; Existing utilize common valve can be in valve part surface coking and carbon deposit; Especially in the matching gap between movable members, constantly the carbonizing matter of accumulation and residual carbon make between the part and solidify each other, cause dyskinesia; Even can't move, make valve total failure.Because therefore the particularity of this processing medium need the pipeline block valve of special-purpose valve products as line transportation high temperature sludge wet goods high viscosity medium.
China's delayed coking unit valve mainly is at present:
1, use general industry to use gate valve; Because water, oil, gas and low viscosity medium apparatus that general gate valve can only be used to clean do not have the function of anti-coking and carbon deposit, so tar can accumulate to positions such as sealing surface, stem packing rapidly; And carbonization is set in together; Valve sealing face was lost efficacy, cause valve switch not in place, even can't move.These valves have to use reluctantly after frequent change or the frequent dismounting removing coking;
2, use the metal hard-sealing stopcock, because the area of contact between faucet body and the valve body is big, when using in the tar medium operating mode; Tar is bonded on the faucet body surface easily; Tar also can get in the body cavity simultaneously, causes valve switch not in place, influences the sealability and the working life of valve.And under worst hot case, Yin Gaowen expands and stuck between faucet body and the valve body, can not normally open and close.
The model utility content
The purpose of the utility model is to solve the deficiency of above-mentioned valve; And provide a kind of simple in structure; Sealing is reliable, and can stop residual oil coking and deposition, solves the problem that all movement parts are caused valve to open by the residual oil bonding in the valve effectively; It is safe and reliable to reach performance, the anti-coking ball valve of long service life.
The utility model provides a kind of anti-coking ball valve; Comprise main valve body, auxiliary valve body, bonnet, spheroid, valve rod, moving valve seat, bellows, bellows sheath, quiet valve seat, gasket seal, stuffing box packing, Electric actuator; Main valve body is connected the back and forms the valve body body cavity with auxiliary valve body, spheroid is housed in the body cavity, and there are quiet valve seat and two valve seats of moving valve seat in the spheroid both sides; Moving valve seat is equipped with bellows at the back and is connected with main valve body; Protecting jacket is equipped with in the inboard of bellows, and bonnet is installed on the main valve body, in bonnet, is provided with stuffing box packing; On main valve body, be respectively equipped with three be connected with the inboard of bellows, the steam blowing equipment that the outside is connected, body cavity is connected of bellows, on bonnet, also be provided with the steam blowing equipment that is connected with filler simultaneously.
Preferentially, between said quiet valve seat and the auxiliary valve body one deck gasket seal is set.
Preferentially, between said valve rod and the bonnet thrust washer is housed.
Preferentially, spheroid adopts bar ball integral structure, can solve valve effectively and press off in the process of opening valve rod at band and is connected with the flat side of spheroid and is out of shape and causes valve switch problem not in place, and the while can be improved the concentricity of spheroid and valve rod, assurance valve usability.
Preferentially, valve mechanism adopts the float-ball type structure.
Preferential; Valve seat adopts the automatically cleaning blade construction; The scraper type valve seat remains tight the contact with sphere under the effect of prefastening load and medium power; Because medium is residual oil or the coking oil gas that contains coke powder, spherome surface can be stained with one deck tar, and valve automatically cleaning blade construction valve seat in opening process can be automatically strikes off the tar of spherome surface.
Preferentially, ball seal face and sealing surface of seat adopt supersonic spray coating that the corrosion and wear resistant alloy material is arranged, and can solve the appearance of sealing surface spot corrosion problem effectively, prolong the working life of valve.Because the medium sulfur-bearing of circulation, traditional ball seal face and sealing surface of seat adopt the chromium plating hardening process to be easy to generate spot corrosion or the chromium plating hardened layer comes off, scratch sealing surface with the spheroid rotation, influence the usability of valve.
The beneficial effect of the utility model:
1) valve adopts the float-ball type structure, and utilize bellows will move valve seat and be pressed on the sphere and and cooperate the location of realizing spheroid with quiet valve seat, be that valve base sealing provides impacting force through bellows as elastic element, the while is also as the temperature compensation effect;
2) medial and lateral of bellows are connected with steam blowing equipment; So both can prevent carbonizing matter and residual carbon from getting into and be accumulated to and cause bellows to follow the string on the bellows, can prevent also that the bellows unstability from causing inhomogeneous to the impacting force of valve seat and leakage that cause simultaneously;
3) adopt steam blowing equipment that valve internal is purged and can stop residual oil coking and deposition, solve the problem that all movement parts are caused valve to open by the residual oil bonding in the valve effectively, it is better to reach sealing effect, long service life.
