Abstract
A hard seal ball valve comprises a joint, a valve block, a snap spring, a belleville spring, a right valve seat, a ball, a left valve seat, a valve stem, a bearing, a washer, a quartered ring, a packing seat, packing, a packing cover, a fixing block, a positioning pin, an another washer, an another snap spring and a socket head cap screw. The hard seal ball valve is characterized in that the left valve seat is inlaid in a valve seat hole of the valve block, the ball is located between the left valve seat and the right valve seat, the ball and the left and right valve seats are in hard seal, the left valve seat and the ball are fixed in the valve seat hole of the valve block through the right valve seat and tension of the belleville spring and the snap spring, the joint is electrically welded to the valve block, and one end of the valve stem is inserted in a ball groove to allow the ball to rotate. The bearing and the washer are sleeved on the valve stem, the quartered ring is disposed in the valve block to fix the valve stem, the packing seat, the packing and the packing cover are sleeved on the valve stem and are fixed on the valve block by the socket head cap screw, and rotation angle of the valve stem is achieved by bilateral limiting by the positioning pin and a positioning block.
Description
Technical field
The utility model belongs to valve technology field, particularly relates to a kind of hard seal ball valve that is applied in the pipeline system.
Background technique
Ball valve is widely used in chemical industry, oil, the mine, electric power, the energy, building, in the industrial processes such as environmental protection, a kind of general engineering goods, it is installed on the various pipelines, the flow that is used for control pipeline medium, flow to and pressure, traditional ball valve in use, when the cambered surface of the valve ball sphere that does not have penetration hole and valve seat fits like a glove, ball valve is realized closing, the seal degree of ball valve, the seal degree that depends on sphere and valve seat cambered surface, known valve seat is comprised of the valve seat of metal manufacturing and the seal ring of nonmetal manufacturing, because the repeatedly unlatching of ball valve causes the seal ring of nonmetal manufacturing to be subject to repeatedly extrusion-deformation, or because the stronger special media of some corrosivity makes its swelling, and and produce microgap between metal seat valve and cause leakage, strengthened the keying operational torque, cause ball valve to use.
Summary of the invention
In order to overcome between existing the ball valve metal seat valve and nonmetal seal ring, since ball valve is in use opened repeatedly or pipeline in the nonmetal seal ring that causes when carrying corrosivity than strong medium and this deficiency of microgap between the metal seat valve, the purpose of this utility model provides easily reliable hard seal ball valve of a kind of simple in structure, high-performance sealed, operation.
The purpose of this utility model is achieved by following technological scheme:
A kind of hard seal ball valve, comprise joint, valve body, jump ring, butterfly spring, right valve seat, spheroid, left valve seat, valve rod, bearing, pad, four minutes rings, the filler seat, filler, follower, the maintenance piece, locating stud, pad, jump ring, socket head screw, it is characterized in that described left valve seat is bumped in the valve seat orifice of valve body, spheroid is positioned at left valve seat, between the right valve seat, spheroid and right valve seat, form hard sealing between the left valve seat, left valve seat and spheroid keep right valve seat and butterfly spring, the tension force of jump ring is fixed in the valve seat orifice of valve body, connect with electric welding between joint and the valve body, one end of valve rod is packed in the spheroid groove, and spheroid can be rotated.Bearing, pad are sleeved on the valve rod, and ring was contained in the valve body in four minutes, played fixedly valve rod.Filler seat, filler, filler pressing sleeve are sleeved on the valve rod, and are fixed on the valve body with socket head screw, and the angle of valve rod rotation is by the spacing realization in both sides of locating stud and positioning block.
The beneficial effects of the utility model are:
Because hard seal ball valve has been made the sealing surface that fits like a glove with valve ball at left valve barrel, downstream valve seat and seal ring that conventional ball valve is placed at the left valve barrel place have been replaced, by directly fitting like a glove of spheroid and left valve barrel, consisted of the sealing of ball valve, owing to cancelled downstream valve seat and the nonmetallic seal ring at left valve barrel place, ball valve in the course of the work, directly produce sealing by left valve barrel and ball, thereby avoided because of ball valve repeatedly open or pipeline in the downstream valve seat that causes when carrying the stronger medium of corrosion and the swelling set of seal ring, the ball valve of generation is little lets out interior leakage.Because having cancelled downstream valve seat and nonmetal seal ring in the ball valve, guaranteed the direct close contact of spheroid and left valve barrel, connect with electric welding between joint and the valve body, improved the sealability of ball valve.
