Abstract
The utility model discloses a top entry ball valve of a forge welding valve body. A middle valve body and a side valve body are welded into the forge welding valve body through a welding line. A ball body lower supporting is fixed on the middle valve body, an upper supporting shaft is fixed on a valve cover, and the middle valve body is connected with the valve cover in a threaded mode. A valve rod penetrates through the valve cover and is connected with a ball body, the valve rod is connected with an actuator, and the actuator drives the valve rod. The valve rod is connected with the ball body and drives the ball body to rotate by 90 degrees through a rectangular groove, and then opening and closing of the ball valve are achieved. The top entry ball valve of the forge welding valve body has the advantages that due to the fact that the top entry structure is adopted, the top entry ball valve of the forge welding valve body can be taken out for maintaining and changing only by opening the valve cover, and therefore the top entry ball valve of the forge welding valve body is simple and convenient. In addition, forge pieces are adopted in the middle valve body and the side valve body, and the forge welding structure is adopted in the valve body, so that outer leakage is ensured to not happen.
Description
Technical field
The utility model relates to a kind of upper-mounting type ball valve, particularly a kind of upper-mounting type ball valve of smithwelding valve body.
Background technique
The open-shut device of ball valve is a spheroid, utilizes spheroid to revolve around the axis of valve rod and turn 90 degrees, and realizes the purpose of opening and closing.Ball valve mainly contains integral type, disome formula, trisome formula, goes up four kinds of structures of dress formula.After the ball valve of integral type, disome formula, trisome formula structure is installed on the pipeline,, must whole ball valve be all pulled down just and can repair and change in case break down or wear out.Under the operating conditions of reality, repair and change the difficult realization of ball valve, need to cut down like the ball valve that adopts welding ends from pipeline, also will consume great amount of manpower and material resources and time simultaneously.On flowing medium pipelines such as petrochemical industry, the long-time parking of some process pipelines is unallowed, and the ball valve of last dress formula structure only need be opened valve gap can take out maintenance and replacing with internals, and therefore adopting the ball valve of going up dress formula structure is optimal selection.
The valve body of traditional upper-mounting type ball valve adopts foundry goods.Because, possibly there are outer defectives such as shrinkage cavity, loose, pore, slag inclusion not as good as forging in the compactness of foundry goods, also has the residual stress in the foundry goods to be difficult to control, this all reduces the mechanical property of foundry goods greatly, causes the external leakage of valve body easily.In addition, the valve seat of traditional upper-mounting type ball valve adopts outer detent pin to fix, and also causes the external leakage of valve body easily.
The model utility content
The utility model technical problem to be solved is to provide a kind of valve body to adopt the upper-mounting type ball valve of smithwelding structure.
In order to solve above technical problem; The utility model provides a kind of upper-mounting type ball valve of smithwelding valve body, comprises middle valve body, weld seam, side valve body, circlip, valve seat bracing ring, cylindrically coiled spring, valve component, spheroid, valve rod, valve gap, stuffing box gland, actuator; Wherein, middle valve body and side valve body are welded into a smithwelding valve body by weld seam, and the spheroid lower support is fixed on the middle valve body; The upper support axle is fixed on the valve gap, and middle valve body and valve gap are spirally connected, and a valve rod runs through valve gap and connects with spheroid; Valve rod is connected with actuator; Actuator drives valve rod, and valve rod connects the 90 degree rotations of drive spheroid through rectangle groove, realizes the ON/OFF of ball valve.Because valve body adopts the smithwelding structure, can guarantee no external leakage.
Said valve gap and middle valve body joint are provided with the pad of anti-external leakage.
Be provided with stuffing box gland between said valve gap and the valve rod, be equipped with the O RunddichtringO inside and outside the stuffing box gland.Guarantee no any leakage between valve rod and the valve gap.
The space that reservation valve seat bracing ring, cylindrically coiled spring, valve component move to both sides, runner hole on the side valve body.Valve seat bracing ring, cylindrically coiled spring, valve component are packed into earlier on the side valve body.In the middle of valve seat bracing ring and the valve component cylindrically coiled spring is set pretightening force is provided,, also enough seal pressures can be provided, guarantee the stable utilization of valve long lifetime, guarantee effectively that simultaneously the valve pocket superpressure discharges automatically even under the small pressure difference operating mode.Before the spheroid of packing into is installed, need with special tooling valve seat bracing ring, cylindrically coiled spring, valve component to be moved to both sides, runner hole earlier.With special tooling the valve seat bracing ring is drawn close until valve component to centre of sphere direction with valve component again behind the valve body during spheroid is packed into and closely contacted with spheroid.Use built-in circlip with valve seat bracing ring fixed-site again, prevent that the valve seat bracing ring from moving to both sides, runner hole, guarantee that valve component closely contacts with spheroid all the time.
On the valve body, the upper support axle was fixed on the valve gap during spheroid lower support axle was fixed on.When upper reaches pressure medium acts on the spheroid, thrust is in time cleared up on middle valve body, valve gap and pipeline through supporting axle up and down, and does not act on the valve rod.Spheroid can carry out different hardening processes, like nickel plating phosphorus, chromium plating, supersonic spray coating etc. according to the difference of service condition.
The superior effect of the utility model is:
1) owing to adopt to go up dress formula structure, only need open valve gap and can internals taken out maintenance and changed being contained in valve on the pipeline, simple and convenient;
2) the middle valve body of the upper-mounting type ball valve of smithwelding valve body and side valve body adopt forging, and middle valve body and side valve body are welded into a smithwelding valve body by weld seam, after postweld heat treatment, after fine finishing, become a weld assembly; No external leakage;
3) valve seat adopts built-in circlip to fix, and is simple in structure, no external leakage.
