Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making under the creative work prerequisite, and the every other embodiment who is obtained belongs to protection domain of the present invention.
The invention discloses a kind of installation method of gate valve, guarantee that still can effectively close after the wearing and tearing appears in the valve rod of gate valve and the screw thread between the flashboard, reach to prolong the gate valve purpose in working life, reduce the cost of production of enterprise.
Referring to Fig. 1, Fig. 1 is a gate valve mounting structure schematic representation disclosed by the invention.
The water outlet 1 and the water inlet 2 of gate valve are arranged at same level height, and water outlet 1 is connected with pipeline 3, and water inlet 2 is connected with pipeline 4; The valve rod 5 of gate valve vertically is provided with; The operation setting stick 6 of gate valve is positioned at the top of current mounting point.
Gate valve can only standard-sized sheet and complete shut-down in pipeline, can not do to regulate and throttling.Flashboard 7 is as the open-shut device of gate valve, and its traffic direction and flow direction are perpendicular, along with the lifting of flashboard 7 or the standard-sized sheet and the complete shut-down of the realization gate valve that descends.
Valve rod 5 can be lifting bar or swingle in force.Be connected by screw thread between valve rod 5 and the flashboard 7.Can be that valve rod 5 is provided with outside thread, flashboard 7 be provided with the internal thread that cooperates with this outside thread.Also can be that valve rod 5 is provided with internal thread, flashboard 7 be provided with the outside thread with this screw-internal thread fit.
By rotating operation setting stick 6, control valve rod 5 operations, and drive the opening and closing of flashboard 7 liftings or the realization gate valve that descends.
Gate valve in use for some time, the screw thread between valve rod 5 and the flashboard 7 can wear and tear.When the needs closing gate valve, the rotating operation setting stick is owing to the screw thread between valve rod 5 and the flashboard 7 experience wear, so when valve rod 5 moved to the lowermost end of its stroke, flashboard 7 is the bottom of no show valve seat 8 also, can not close and put in place.There is this as seen, after the screw thread between valve rod 5 and the flashboard 7 weares and teares, adopts the mode of forced seal, can't rely on external force to act on operation setting stick 6, flashboard 7 is pressed to the bottom of valve seat 8 by force, cause to realize closing fully of gate valve.
