Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of steel ball-type shuttle valve.
Background technique
Valve (valve) is mounted in the equipment that is used for controlling fluid flow in pipeline, is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve can be divided into and block class, non-return class, security classes, adjusting class, shunting class by effect and purposes; By nominal pressure, can be divided into vacuum valve, low pressure valve, middle pressure valve, high pressure valve, excess high pressure valves; By operating temperature, can be divided into ultra-low temperature valves, low temperature valve, normal temperature valve, middle temperature valve, high-temperature valve; By driving mode, can be divided into self-acting valve, motivational drive valve, manually operated valve.
Shuttle valve is a kind of pressure selection valve, is equivalent to two one-way valves, can, by comparing the pressure size of two-way liquid medium, come selection pressure great mono-tunnel to communicate with liquid outlet.A kind of three-way shuttle valve as disclosed in Chinese utility model patent CN201715029U, comprise valve body, the liquid outlet opening that there is feed pathway on described valve body and be positioned at feed pathway medium position and be connected with feed pathway, in described feed pathway, be provided with the steel ball that can move along feed pathway, the diameter of described steel ball is greater than the diameter of liquid outlet opening, the steel ball of the first liquid feeding end of described feed pathway described in having when being subject to the fluid pressure of feed pathway the second liquid feeding end can against and with the position structure of its formation sealing, the second liquid feeding end of described feed pathway is provided with the block piece that can stop steel ball when steel ball is subject to the fluid pressure of feed pathway the first liquid feeding end, on described block piece, there is the inlet opening being communicated with feed pathway, when being resisted against on block piece, described steel ball can seal up above-mentioned inlet opening.The advantages such as that this three-way shuttle valve has is simple in structure, good airproof performance.Figure of description from this model utility, the first liquid feeding end of valve body and the second liquid feeding end outside are provided with outside thread, for being connected with outer connecting pipe nut, for keeping good sealability, need to inner conical surface be set at the first liquid feeding end and the second liquid feeding end, to be tightly connected with the male cone (strobilus masculinus) of outer connecting pipe, so requirement on machining accuracy is high, processing cost is high.
Model utility content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, processing cost is low, the steel ball-type shuttle valve of good seal performance.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of steel ball-type shuttle valve, comprise the valve body that offers feed pathway, in described feed pathway, be provided with the steel ball along its rolling, at least one end of described feed pathway is provided with internal thread, in it, be bolted with pipe joint, in described pipe joint, be provided with inlet opening, the diameter of this inlet opening is less than the sphere diameter of described steel ball; The nearly steel ball end of described inlet opening is provided with inner conical surface.In said structure, the nearly steel ball end of described inlet opening is provided with inner conical surface, forms conical surface seal, good airproof performance with steel ball.
Wherein, the two ends of described feed pathway are internal thread segment, and the internal thread segment diameter that relatively described inlet opening is positioned at described steel ball heteropleural is less than described steel ball size.
Wherein, in one section of described feed pathway between internal thread segment described in two, it is steel ball rolling section, the internal thread segment that relatively described inlet opening is positioned at described steel ball heteropleural is connected with described steel ball rolling section by taper hole section, and described taper hole section and steel ball form conical surface seal, good airproof performance.
Wherein, on described valve body, be also provided with the liquid outlet opening being communicated with described feed pathway, and described liquid outlet opening diameter is less than steel ball size.
Steel ball of the present utility model rolls in steel ball rolling section, is subject to the conical surface of the inlet hydraulic shutoff the other end of feed pathway one end, and feed pathway is communicated with liquid outlet opening, realizes shuttle valve function.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, feed pathway end is provided with internal thread, is convenient to pipe joint and is connected with valve body internal thread, the inner conical surface coordinating with outer connecting pipe need to be set on valve body, simple in structure, processing cost is low; Meanwhile, steel ball and feed pathway adopt conical surface seal, good seal performance.
