Abstract
The utility model relates to a kind of hemisphere arc valve, comprises valve plate body, and the sealing surface side of the valve plate body between described upper joint and lower joint is plane, and an other side of this valve plate body is hemisphere arc shaped surface; Valve plate body interior between described upper joint and lower joint is shaped with the cavity of several hollow.This valve plate 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.
Description
Technical field
The utility model belongs to valve technology field, especially a kind of hemisphere arc valve.
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.
Valve plate of the prior art is mostly iron and steel material quality, and valve plate is all solid mostly, and weight is all heavier, and this brings great inconvenience not only to the carrying, operation etc. of operator, and greatly wastes raw material, wastes resource; In addition, the outer surface of existing valve plate is mostly plane, and plane is stressed bad, and discontinuity easily produces eddy current, brings great inconvenience to use.
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 hemisphere arc valve that not easily produces eddy current, improve working life, improve working efficiency.
The technological scheme that the utility model technical solution problem adopts is:
A kind of hemisphere arc valve, comprise valve plate body, the axis position of described valve plate body is shaped with valve shaft passage vertically, the upper/lower terminal at the axis position of described valve plate body is shaped with joint and lower joint respectively, described upper joint with on lower joint all vertically symmetry be shaped with radial pin and be connected blind hole, this pin connects blind hole and is used for valve plate and valve shaft to link together;
The sealing surface side of the valve plate body between described upper joint and lower joint is plane, and an other side of this valve plate body is hemisphere arc shaped surface; Valve plate body interior between described upper joint and lower joint is shaped with the cavity of several hollow.
And, the sealing surface side of described valve plate body 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 valve plate body of the side of fixing part arranges a screw, sealing circle is installed in valve plate body interior by screw, and this contact head extends outside valve 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 valve plate 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.
2, this valve plate 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 the using state signal connection of Fig. 1 partly cuts open figure;
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.
A kind of hemisphere arc valve, as depicted in figs. 1 and 2, comprise valve plate body 1, the axis position of described valve plate body is shaped with valve shaft passage 4 vertically.
Innovative point of the present utility model is:
The upper/lower terminal at the axis position of described valve plate body is shaped with joint 3 and lower joint 6 respectively, described upper joint with on lower joint all vertically symmetry be shaped with several radial pin and be connected blind hole 5, this pin connects blind hole and is used for valve plate and valve shaft to link together;
The sealing surface side 10 of the valve plate body between described upper joint and lower joint is plane, and an other side of this valve plate body is hemisphere arc shaped surface 2; 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 improves the working life of this valve plate, also improves working efficiency simultaneously.
Valve plate body interior between described upper joint and lower joint is shaped with the cavity 8 of several hollow, in the present embodiment, the quantity of described cavity is 3, the setting of the cavity of this hollow, the weight of this valve plate is obtained widely alleviate, save resource, also saved the cost of production of manufacturing enterprise simultaneously, improve the economic benefit of enterprise.
As shown in Figure 3 and Figure 4, the sealing surface side of described valve plate body coaxially arranges a seal ring 7, described seal ring comprises fixing part 13 and contact head 14, described contact head is formed on the side of fixing part, the valve plate body of the side of fixing part arranges a screw 9, sealing circle is installed in valve plate body interior by screw, and this contact head extends outside valve plate body and also can contact with the sealing surface 11 of valve body 12.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.
