Background technique
Electric Actuated Stop Valves is that most popular a kind of drive motor that adopts carries out the stop valve driven, its structure includes the parts such as valve body, valve gap, valve rod, flap, support, drive motor and filler, its valve body is provided with snout cavity and outlet plenum, the connecting port of a level is set between snout cavity and outlet plenum, flap is installed on valve rod, and is opened connecting port by valve rod driving mechanism vertical-lift or transfer or closed connecting port and carry out opening/shutting valve.
This traditional Electric Actuated Stop Valves, when being applied to firepower power station backwater condenser system and the field such as oil, chemical industry requires in the system pipeline with isolated from atmosphere, being difficult to ensure the gland sealed sealing between valve rod and valve gap, there is potential safety hazard.
In addition, the drive motor of existing actuate valve stem oscilaltion is all loaded on the end, outer end that valve rod passes outside valve gap, and in use with valve rod oscilaltion, this just makes the rising of valve rod and drive motor to take certain space, if Electric Actuated Stop Valves is just arranged on comparatively narrow and small place, a space, just in time there are other objects again or above the position of Electric Actuated Stop Valves installation, then will certainly affect the normal keying of Electric Actuated Stop Valves, bring inconvenience to user.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides the good airproof performance between a kind of valve rod and valve gap, and can not the water seal Electric Actuated Stop Valves of the occupying volume external space in opening/shutting valve process.
For achieving the above object, the technical solution of the utility model includes valve body, valve gap, flap, valve rod and valve rod lift drive mechanism, valve body is provided with valve seat, body cavity is divided into upper chamber and lower chambers by valve seat, the lower end of valve rod is fixed in described flap interlock, and this flap is positioned at upper chamber and adaptive with valve base sealing, described valve gap includes elongation neck, elongation inner chamber is provided with in this elongation neck, the top of described valve rod is through extending inner chamber and being linked with valve rod lift drive mechanism
Described valve rod lift drive mechanism comprises drive shell, and the drive motor be fixedly installed in drive shell, described drive shell includes the base plate be fixed on valve body and the driving lid be fixed on base plate, on described base plate, the corresponding inner chamber that extends is provided with screw in axial outer end, the top of described valve rod forms the flank of thread of threaded engagement through extending inner chamber and being provided with one section with described screw, described drive motor is linked by driving mechanism and valve rod, described driving mechanism includes rotating shaft, active oblique gear, driven helical gear, first gear and the second gear, described rotating shaft is loaded in drive shell, active oblique gear is loaded on drive motor output shaft, driven helical gear to be loaded in rotating shaft and to be meshed with active oblique gear, the first described gear is also loaded in rotating shaft, the second described gear is loaded on valve rod and is positioned on the outer end of drive shell, and be meshed with the first gear,
The avris of the described relative valve rod of elongation neck is provided with packing cavity, this packing cavity is disposed with filler lower support seat, filler and filler pressing sleeve from top to bottom, described filler pressing sleeve is spacing is outward provided with the hold-down grid be fixed on support, the outer wall of described elongation neck is provided with the intake pipe and waste pipe that communicate with packing cavity, the inner being positioned at packing cavity of described intake pipe is provided with the water-injecting cavity be positioned in the middle part of filler.
Further setting is that the sidepiece of described valve body has been wholely set side attachment post, and the upper end of this side attachment post is fixedly connected with described base plate.
The beneficial effects of the utility model are: by above-mentioned driving mechanism, drive motor is fixed in drive shell all the time, and this drive motor can not be elevated along with the lifting of valve rod, therefore in opening/shutting valve process, this valve can not the occupying volume external space, thus also would not because affect the normal keying of valve by spatial constraints.In addition, the present embodiment arranges intake pipe and outlet pipe on elongation neck, supplies high pressure water, utilize hydraulic pressure that filler is expanded by this intake pipe in the water-injecting cavity in packing cavity, thus the sealing having ensured valve rod and extended between neck.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
