Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of dual-valve structure that can mutually link.
Background technique
At present, conventionally each deck valve door is all with a drive unit independently, people conventionally control described drive unit and can realize the unlatching of valve or close, described drive unit can be manual driving device as handwheel, tommy bar or gear transmission structure, can be also Electric actuator, Pneumatic actuator or Hydraulic actuator etc.
In actual applications, on a lot of pipe-line systems or equipment, often have two deck valve doors, and this two deck valves door also needs to possess when a valve opening wherein, another deck valve door can be closed automatically; When a valve closing wherein, another deck valve door can be opened automatically, thereby guarantees pipe-line system or equipment safe operation all the time.But due to existing every deck valve Men Jun be by its separately independently drive unit control to drive, and because of the variation of existing drive unit, therefore wanting to realize two synchronous interactions between different driving device there are more technological difficulties.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of simple in structure, and can realize the dual-valve structure of synchronous interaction each other.
For achieving the above object, the invention provides a kind of dual-valve structure that can mutually link, include the first valve and the second valve, wherein the first valve includes the first valve body, the first flap and the first valve rod, the first flap is loaded in the first valve body, the first valve rod is arranged in the first valve body, and the inner of the first valve rod and the first flap are fixed, the second valve includes the second valve body, the second flap and the second valve rod, the second flap is loaded in the second valve body, the second valve rod is arranged in the second valve body, and the inner of the second valve rod and the second flap are fixed, the end, outer end of described the first valve rod is connected with drive unit, between described the second valve rod and the first valve rod, be provided with linkage, described linkage includes the first fixing pin, the second fixing pin and a linkage block, the first fixing pin is installed on the first valve rod, the second fixing pin is installed on the second valve rod, one end of described linkage block is provided with the first fixing pin and forms the first rail slot that interlock slippage coordinates, the other end of described linkage block is provided with the second fixing pin and forms the second rail slot that interlock slippage coordinates.
The invention has the beneficial effects as follows: adopt said structure, because the present invention is only provided with drive unit on the first valve, and by linkage, link between the first valve and the second valve, therefore so not only simplified widely valve mechanism, and can also effectively guarantee the synchronous interaction between two deck valve doors, owing to only having a drive unit, operate also more convenient.
The present invention can further be set to the described preferred zigzag structure of linkage block, the first described rail slot and the second rail slot are opened in respectively on the upper and lower horizontal edge of zigzag linkage block, on fillet between described upper and lower horizontal edge, be also provided with a hinged rotatingshaft, on the first described valve, be fixed with a support, on described support, be fixed with and can form the hinged support block being rotatably assorted with described hinged rotatingshaft.
Adopt said structure, described linkage block is arranged to zigzag, and the first rail slot and the second rail slot are opened in respectively on the upper and lower horizontal edge of zigzag linkage block, the structure that can make described linkage block is compact and reasonable more.Simultaneously, on the fillet between described upper and lower horizontal edge, be also provided with one and can form the hinged hinged rotatingshaft being rotatably assorted with the first valve, by the effect of described hinged rotatingshaft, described linkage block can only be rotated around this hinged rotatingshaft, thereby being linked of linkage can more smooth and easyly be stablized.Certainly, described hinged rotatingshaft also can form hinged being rotatably assorted with the second valve.
The present invention also can further be set to the first described rail slot and the second rail slot is all to be connected and composed by one section of straight-line groove and one section of bending groove, and when the first fixing pin is positioned at the straight-line groove section of the first rail slot, the second fixing pin correspondence is positioned in the bending groove section of the second rail slot; When the first fixing pin is positioned at the bending groove section of the first rail slot, the second fixing pin correspondence is positioned in the straight-line groove section of the second rail slot.
Adopt said structure, during due to valve opening, the driving force of drive unit is to become gradually large by little, therefore when the first valve opening, described the first fixing pin progressively slides onto straight-line groove section by the bending groove section of the first rail slot, and the actual driving force in the time of fully adapting to valve opening changes demand; Simultaneously, during due to valve closing, the driving force of drive unit is by diminishing greatly gradually, therefore when the second valve closing, described the second fixing pin progresses into bending groove section by the straight-line groove section of the second rail slot, and the actual driving force in the time of also fully adapting to valve closing changes demand.Otherwise, the first valve closing, the second valve opening is also in like manner.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
