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, usually each deck valve door is all with an independently drive unit, people control unlatching or the closedown that described drive unit can realize valve usually, described drive unit can be manual driving device as handwheel, tommy bar or gear transmission structure, also can be Electric actuator, Pneumatic actuator or Hydraulic actuator etc.
In actual applications, a lot of pipe-line system or equipment often have two deck valve doors, and this two deck valves door also needs to possess when a wherein valve opening, another deck valve door can be closed automatically; When a wherein valve closing, another deck valve door can be opened automatically, thus ensures that pipe-line system or equipment can safe operations 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 want the synchronous interaction realized between two different driving devices and there are more technological difficulties.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of structure simple and the dual-valve structure of synchronous interaction each other can be realized.
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, first flap and the first valve rod, first flap is loaded in the first valve body, first valve rod is arranged in the first valve body, and the inner of the first valve rod and the first flap are fixed, second valve includes the second valve body, second flap and the second valve rod, second flap is loaded in the second valve body, 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 first valve rod is connected with drive unit, linkage is provided with between described second valve rod and the first valve rod, described linkage includes the first fixing pin, second fixing pin and a linkage block, first fixing pin is installed on the first valve rod, second fixing pin is installed on the second valve rod, one end of described linkage block is provided with the first rail slot forming the slippage that links with the first fixing pin and coordinate, the other end of described linkage block is provided with the second rail slot forming the slippage that links with the second fixing pin and coordinate.
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 linked by linkage between the first valve and the second valve, therefore not only significantly simplify valve mechanism like this, and the synchronous interaction can also effectively guaranteeing between two deck valve doors, owing to only having a drive unit, operate also more convenient.
The present invention can be set to the preferred zigzag structure of described linkage block further, the first described rail slot and the second rail slot are opened on the upper and lower horizontal edge of zigzag linkage block respectively, fillet between described upper and lower horizontal edge is also provided with a hinged rotatingshaft, the first described valve is fixed with a support, described support is fixed with and can forms the hinged support block be rotatably assorted with described hinged rotatingshaft.
Adopt said structure, described linkage block is arranged to zigzag, and makes the first rail slot and the second rail slot be opened on the upper and lower horizontal edge of zigzag linkage block respectively, the structure compact and reasonable more of described linkage block can be made.Simultaneously, fillet between described upper and lower horizontal edge is also provided with one and can forms the hinged hinged rotatingshaft be rotatably assorted with the first valve, by the effect of described hinged rotatingshaft, described linkage block can only be rotated around this hinged rotatingshaft, thus 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 be set to the first described rail slot further and the second rail slot is all 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 becomes large gradually, therefore when the first valve opening by little, described first fixing pin progressively slides onto straight-line groove section by the bending groove section of the first rail slot, fully can adapt to actual driving force change demand during valve opening; Simultaneously, during due to valve closing, the driving force of drive unit is by diminishing gradually greatly, therefore when the second valve closing, described second fixing pin progresses into bending groove section by the straight-line groove section of the second rail slot, also fully can adapt to actual driving force change demand during valve closing.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.
