Background technique
Valve (famen) is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Industrial valves door type is varied, is widely used in the industries such as chemical industry, food, water, electricity, mainly plays Flow-rate adjustment and the cut-off effect of flowing medium.
The valve plate being applicable to the butterfly valve of water or sewage of the prior art is mostly iron and steel material quality, and valve plate is all solid mostly, weight is all heavier, and this brings great inconvenience not only to the carrying, operation etc. of operator, and greatly waste raw material, waste resource; And the outer surface of the valve plate of existing butterfly valve is mostly plane, and plane is stressed bad, and discontinuity easily produces eddy current, brings great inconvenience to use.In addition, the sealing surface of the valve body of existing butterfly valve due to the frequency used higher, very easily wear damage, causes the working life of butterfly valve shorter, brings loss to manufacturing enterprise, improve the manufacturing efficiency of enterprise, also greatly wastes resource simultaneously.
Model utility content
The purpose of this utility model is the deficiency overcoming original technology, provides that a kind of design science is reasonable, structure is simple, uniform force, the seal butterfly valve that not easily produces eddy current, improve working life, improve the band half spherical arc shape butterfly plate of working efficiency.
The technological scheme that the utility model technical solution problem adopts is:
The seal butterfly valve of a kind of band half spherical arc shape butterfly plate, comprise valve body, upper axle, bearing, axle sleeve, butterfly plate, lower shaft and lower cover, described butterfly plate is coaxially installed in valve body, axle on coaxial package on the valve body above this butterfly plate, coaxial package lower shaft on the valve body below this butterfly plate; This bearing settlement in the top of valve body and coaxial package outside upper axle, the outer co-axial seal suit of the upper axle on this between axle and valve body axle sleeve; Co-axial seal suit lower cover on lower shaft below described valve body,
Described butterfly plate comprises butterfly plate body, the axis position of described butterfly plate body is shaped with valve shaft passage vertically, the upper/lower terminal at the axis position of described butterfly plate body is shaped with joint and lower joint respectively, described upper joint with on lower joint all vertically symmetry be shaped with several radial pin and be connected blind hole, this pin connects blind hole and is used for butterfly plate and upper axle and lower shaft to link together;
The sealing surface side of the butterfly plate body between described upper joint and lower joint is plane, and an other side of this butterfly plate body is hemisphere arc shaped surface; Butterfly plate body interior between described upper joint and lower joint is shaped with the cavity of several hollow; Described valve body is magnesium iron, the sealing surface weld deposit stainless steel lining of this valve body.
And, the sealing surface side of described this plate of butterfly plate coaxially arranges a seal ring, described seal ring comprises fixing part and contact head, described contact head is formed on the side of fixing part, the butterfly plate body of the side of fixing part arranges a screw, sealing circle is installed in butterfly plate body interior by screw, and this contact head extends outside butterfly plate body and also can contact with the sealing surface of valve body.
And the quantity of described cavity is 3.
Advantage of the present utility model and good effect are:
1, this butterfly valve is provided with hemisphere arc shaped surface, this hemisphere arc shaped surface be arranged so that the choked flow of this valve plate reduces widely, and hemisphere arc shaped surface also not easily produces eddy current, and support force have also been obtained to be strengthened widely, and improve the working life of this valve plate, also improve working efficiency simultaneously; In addition, valve plate body interior between the upper joint of this valve plate and lower joint is shaped with the cavity of several hollow, the setting of the cavity of this hollow, the weight of this valve plate is obtained widely alleviate, save resource, also save the cost of production of manufacturing enterprise simultaneously, improve the economic benefit of enterprise; Meanwhile, because this valve body is magnesium iron, built-up welding stainless steel is worn in the sealing of this valve body, greatly extends the working life in sealing face, thus extends the working life of this butterfly valve further.
2, this butterfly valve is provided with seal ring, and sealing circle comprises fixing part and contact head, and the setting of sealing circle further increases the sealing in this valve plate and valve body contact face, and because seal ring is comparatively soft, what therefore also extend this valve plate and valve body makes the life-span.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 partly cuts open figure to cross section;
Fig. 3 is that overlooking of Fig. 1 partly cuts open enlarged view;
Fig. 4 is the II portion structure enlarged diagram in Fig. 3.
Embodiment:
For content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model thus.
The seal butterfly valve of a kind of band half spherical arc shape butterfly plate, as depicted in figs. 1 and 2, comprise valve body 1, upper axle 4, bearing 5, axle sleeve 11, butterfly plate 2, lower shaft 10 and lower cover 9, described butterfly plate is coaxially installed in valve body, axle on coaxial package on valve body above this butterfly plate, coaxial package lower shaft on the valve body below this butterfly plate; This bearing settlement in the top of valve body and coaxial package outside upper axle, the outer co-axial seal suit of the upper axle on this between axle and valve body axle sleeve; Co-axial seal suit lower cover on lower shaft below described valve body.
Innovative point of the present utility model is:
Described butterfly plate comprises butterfly plate body, the axis position of described butterfly plate body is shaped with valve shaft passage (in figure non-label) vertically, the upper/lower terminal at the axis position of described butterfly plate body is shaped with joint 6 and lower joint 8 respectively, described upper joint with on lower joint all vertically symmetry be shaped with several radial pin and be connected blind hole 7, this pin connects blind hole and is used for butterfly plate and upper axle and lower shaft to link together;
