Abstract
The utility model relates to a soft-sealed triple eccentric butterfly valve which comprises a valve body. A valve seat is arranged in a cavity of the valve body, the valve seat is sealed inside to be matched with a valve plate which is fixedly connected with a rotary shaft, and the rotary shaft is arranged in the cavity of the valve body through bearings. The soft-sealed triple eccentric butterfly valve is characterized in that the valve plate comprises a valve plate base fixedly connected with the rotary shaft, a seal ring is arranged at the upper portion edge of the valve plate base, a press ring is arranged above the seal ring, and the press ring, the seal ring and the valve plate base are fixedly connected through a connection piece. The connection piece is a compression screw. The soft-sealed triple eccentric butterfly valve solves problems of large torque of prior double eccentric butterfly valves and trace leakage of metal-sealed triple eccentric butterfly valves. The structure machining is convenient, the seal effect is good, the replacing after abrasion is simple, and the valve plate machining and manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of butterfly valve, especially a kind of soft seal three eccentric butterfly valve of complete zero leakage.
Background technique
In the existing market, the application of valve is very much that extensively the main effect of valve is that flow ends and adjusting.The valve of similar application has double eccentric butterfly valve, the metallic seal three eccentric butterfly valve.A kind of modulating valve simple in structure of butterfly valve can be used for the switch control of low pressure pipeline medium.Butterfly valve is applicable in the engineering systems such as producer, coal gas, rock gas, LPG, town gas, cold and hot air, chemical industry smelting and generation environment-friendly and carries on the pipeline of various corrosivity, non-corrosive fluids medium, is used to regulate and block flowing of medium.Three eccentric butterfly valve has the little advantage of moment of torsion, the good sealing effect of double eccentric butterfly valve, but three eccentric butterfly valve or double eccentric butterfly valve generally do not possess the little performance with good airproof performance of moment of torsion simultaneously.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and a kind of soft seal three eccentric butterfly valve is provided, and the moment of torsion of this three eccentric butterfly valve is little, can reach the effect of zero leakage simultaneously.
According to the technological scheme that the utility model provides, said soft seal three eccentric butterfly valve comprises valve body, in the inner chamber of said valve body, valve seat is set, and the valve seat inner sealing cooperates valve plate, and valve plate is fixedly connected with rotating shaft, and rotating shaft is arranged in the inner chamber of valve body through bearing; Characteristic is: said valve plate comprises the valve plate pedestal that is fixedly connected with rotating shaft, in the top edges of valve plate pedestal seal ring is set, and the top of said seal ring is provided with trim ring, and trim ring, seal ring and valve plate pedestal are fixed together through link.
Said link is a housing screw.
The described soft seal three eccentric butterfly valve of the utility model has solved the problem of problem that the double eccentric butterfly valve moment of torsion is big in the past and metallic seal three eccentric butterfly valve micro-leakage; The structure processing of the utility model is convenient, and sealing effect is better, and the wearing and tearing back is changed also simple, has reduced the manufacturing cost of valve plate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the described valve plate of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1 ~ shown in Figure 2: the soft seal three eccentric butterfly valve comprises valve body 1, valve plate 2, valve plate pedestal 2-1, trim ring 2-2, link 2-3, seal ring 2-4, rotating shaft 3, valve seat 4 etc.
As shown in Figure 1, the utility model comprises valve body 1, and valve seat 4 is set in the inner chamber of said valve body 1, and valve seat 4 inner sealings cooperate valve plate 2, and valve plate 2 is fixedly connected with rotating shaft 3, and rotating shaft 3 is arranged in the inner chamber of valve body 1 through bearing; As shown in Figure 2; Said valve plate 2 comprises the valve plate pedestal 2-1 that is fixedly connected with rotating shaft 3; Top edges at valve plate pedestal 2-1 is provided with seal ring 2-4; The top of said seal ring 2-4 is provided with trim ring 2-2, and trim ring 2-2, seal ring 2-4 and valve plate pedestal 2-1 are fixed together through link 2-3; Said link 2-3 can adopt housing screw; Said valve plate pedestal 2-1, trim ring 2-2 are identical with the material of valve body 1, all adopt metal material to process; Said seal ring 2-4 adopts nonmetal sealing material to process (processing as adopting materials such as rubber, plastics, pottery, graphite), can play sealing effect.
The utility model has solved in the past that two eccentric torque were big, and metallic seal three off-centre have the problem of micro-leakage, and the structure processing of the utility model is convenient, and sealing effect is better, and the wearing and tearing back is changed also simple, has reduced the manufacturing cost of valve plate.
