Abstract
A ball valve in particular relates to a wear-resisting and corrosion-resisting butterfly eccentric ball valve which can truly adjust the flow of the medium and is suitable for all kinds of cold water, hot water, domestic sewage and strong corrosive medium pipes which are used in metallurgy and petrochemical industry. The butterfly eccentric ball valve comprises a valve body and a valve flap. The valve flap is managed in the valve body. A neck bush is managed on the inner wall of the valve inlet. The neck bush and the valve flap form a seal. Because the valve flap moves in the valve body in a butterfly and eccentric mode and the valve body in whole or in part is made of precious metals, the butterfly eccentric ball valve is corrosion-resisting, and the flow of the medium in the pipe is guaranteed to be normal. The service life of the ball valve is prolonged, the work efficiency is increased and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of wear-resisting, corrosion-resistant ball that is applicable to various cold water, hot water, domestic sewage and metallurgical petrochemical industry strong corrosive media pipeline,
And really be the butterfly eccentric ball valve of realizing the flow of adjusting medium.
Background technique
Valve is a kind of piping element of controlling fluid motion.Ball valve is a kind of of valve, and ball valve commonly used is most of to adopt following three kind of structure, the one, and floating ball ball valve, the 2nd, fixing spherical ball valve, the 3rd, elastic ball ball valve.Thereby the rotation by spheroid realizes Fluid Flow in A and cutout effect, wherein regulates ball valve and is divided into two kinds of (1) V-type ball valves by formation; (2) semispherical valve.Its structure also adopts this three kinds of structures, and these two kinds of forms all are applicable to the adjusting of the pipeline of various media.But these two kinds of forms all can cause the rate-of flow loss to the adjusting of medium, do not reach fine adjustment and full flow channel, increase energy consumption, can not be suitable for the requirement of field working conditions.
Summary of the invention
Goal of the invention of the present utility model is for the deficiencies in the prior art, provides a kind of applicable
Regulate rate-of flow in flowing medium and the strong wear-resisting and real realization of strong corrosive media, guarantee that the initial value of flow reaches the butterfly eccentric ball valve of the energy-conserving action of operating mode.
Realize that above-mentioned purpose adopts following technical proposals: a kind of butterfly eccentric ball valve, comprise valve body, flap, valve rod, described flap is positioned at valve body, valve rod is connected with flap, described flap is the butterfly eccentric structure, be provided with interior spiral shell lining in the import of described valve body, flap of spiral shell lining and butterfly eccentric structure forms sealing in this, is full flow channel structure in the valve body.
As preferred version, described flap is the spheroid of full-metallic butterfly plate formula structure.
As preferred version, the angle of described full flow channel adjust flux is 0 °---～100 °.
As preferred version, it is 0 ° that described full flow channel is regulated the rate-of flow angle---～100 °.
Adopt technique scheme, compared with prior art, flap of the present utility model is the spheroid that metal butterfly plate formula material is made, and it is at the valve inner eccentric motion that reverses.Valve body all adopts metallic material to make this set, good seal performance when opening or closing valve.Reduce the valve inner space, prolonged the working life of ball valve.Because in the valve body be full flow channel, rate-of flow is large, resistance is little, loss of head is zero, and level or at right angle setting all can.Because flap is that the structure of butterfly plate formula and valve body is eccentric form, and flap and valve body are all-metal material, not only corrosion-resistant, can regulate again rate-of flow makes its scope from 0 °---～100 ° practical adjustments break-even in full, improve working efficiency, reduced energy consumption, realized energy-conservation real effect.
Description of drawings
Fig. 1 is that the utility model overall structure front elevational schematic is close valve state.
Fig. 2 is opening state structural representation of the present utility model.
Fig. 3 is just semi-open status architecture schematic representation of the present utility model.
Among the figure, valve body 1, interior spiral shell lining 2, flap 3, valve rod 4, full flow channel 5.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Present embodiment is a kind of butterfly eccentric ball valve, and its structure is seen Fig. 1, Fig. 2, Fig. 3.This ball valve is by valve body 1, interior spiral shell lining 2, and flap 3, valve rod 4 compositions such as grade, valve rod 4 is connected with flap 3, and flap 3 is positioned at valve body 1 for butterfly eccentric sphere body structure, and the flap 3 of present embodiment is full-metallic butterfly plate formula structure.Interior spiral shell lining 2 is set in the import of valve body 1, and interior spiral shell lining 2 forms sealing with the flap 3 of butterfly eccentric structure, is full flow channel 5 structures in the valve body 1.
The interior spiral shell lining 2 of valve body 1, valve rod 4 all adopt metallic material to make, and the valve body 1 of present embodiment is all made of Stainless steel 316 L material.
The interior spiral shell lining 2 that arranges in flap 3 and the valve body import adopts titanium alloy, monel metal, Hastelloy, high alloy steel, two-way steel material to make.
Working principle of the present utility model
When fluid when valve inlet flows into, flap 3(spheroid) opens, such as Fig. 2, fluid can be discharged by valve export through full flow channel 5 swimmingly, when flap 3 is opened 25 °, 50 ℃, 75 °, fluid can open up the different flow that opens angle also and then to be changed, because flap 3 is spheroid butterfly plate formula structure, such as Fig. 3, flow mistake when opening several angle, at this moment the butterfly plate owing to flap 3 has the butterfly face just in time to be compensated to the flow by fluid, thereby reaches the effect of not losing fluid flow.
Claims (3)
1. butterfly eccentric ball valve, comprise valve body, flap, valve rod, described flap is positioned at valve body, valve rod is connected with flap, it is characterized in that described flap is the butterfly eccentric structure, be provided with interior spiral shell lining in the import of described valve body, the flap of spiral shell lining and butterfly eccentric structure forms sealing in being somebody's turn to do, and is full flow channel structure in the valve body.
2. butterfly eccentric ball valve according to claim 1 is characterized in that, described flap is the spheroid of full-metallic butterfly plate formula structure.
