Abstract
The invention provides a ball valve, and particularly relates to a butterfly-type eccentric ball valve which is a durable anti-corrosive ball valve and is applicable to cold water medium pipelines, hot water medium pipelines, domestic sewage medium pipelines, and highly corrosive medium pipelines in metallurgy and petrochemical industry and capable of really adjusting the flow rate of the medium. The butterfly-type eccentric ball valve comprises a valve body and valve blades, wherein internal blades are positioned in the valve body; and inner liner sleeves sealed to the valve blades are arranged on the internal wall of the inlet of the valve body. According to the butterfly-type eccentric ball valve, the valve blades run in the valve body in a butterfly eccentric mode; the valve body is completely or partially manufactured by utilizing precious metal, so corrosion resistance can be ensured, and the normal flow rate of the medium in the pipeline can be ensured, the service life of the ball valve is prolonged, the working efficiency is also increased, and the energy loss is reduced.
Description
Technical field
The present invention relates to a kind of ball valve, particularly relate 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 through spheroid realizes that fluid flows and the 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 accurate adjusting 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 invention is the deficiency to existing technology, provides a kind of and is suitable for
Regulate rate-of flow in flowing medium and the strong wear-resisting and real realization of strong corrosive media, the initial value of dependable 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, and valve rod is connected with flap; Described flap is the butterfly eccentric structure; Spiral shell lining in being provided with in the import of said 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 that described full flow channel is regulated flow is 0 °---～100 °.
As preferred version, it is 0 ° that described full flow channel is regulated the rate-of flow angle---～100 °.
As preferred version, described valve body is made with stainless steel material.
As preferred version, described interior spiral shell lining is with titanium alloy or monel metal or Hastelloy or high alloy steel or the making of two-way steel.
Adopt technique scheme, compared with prior art, flap of the present invention is the spheroid of metal butterfly plate formula material, 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 big, resistance is little, loss of head is zero, and level or vertical installation all can.Because flap is that the structure of butterfly plate formula and valve body is an eccentric form; And flap and valve body are all-metal material; Not only corrosion-resistant; Can regulate rate-of flow again makes its scope from 0 °---～100 ° practical adjustments break-even in full, and improved working efficiency, cut down the consumption of energy, realize energy-conservation real effect.
Description of drawings
Fig. 1 is that overall structure front elevational schematic of the present invention is a close valve state.
Fig. 2 is an opening state structural representation of the present invention.
Fig. 3 is a just semi-open status architecture schematic representation of the present invention.
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 present invention is done further description.
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 a full-metallic butterfly plate formula structure.Spiral shell lining 2 in being provided with in the import of valve body 1, 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, valve rod 4 all adopt metallic material to make.The valve body 1 of present embodiment is all with stainless steel 316L material.
The interior spiral shell lining 2 that is provided with in butterfly board-like (spheroid) flap 3 and the valve body import adopts titanium alloy, monel metal, Hastelloy, high alloy steel, two-way steel to make.
Working principle of the present invention
When fluid when valve inlet flows into, flap 3 (spheroid) is opened, like Fig. 2; Fluid can be discharged by valve export through full flow channel 5 swimmingly, and when flap 3 was opened 25 °, 50 ℃, 75 °, the different flow that fluid can lead to opening angle also and then changed; Because flap 3 is a spheroid butterfly plate formula structure, like Fig. 3, fluid flows through when opening several angle; At this moment the butterfly plate owing to flap 3 has the butterfly face to compensate just in time for the flow through fluid, thereby reaches the effect of not losing fluid flow.
