Abstract
The utility model discloses a ball screw valve. A ball screw (6) is connected with a valve rod (3) through a fixing lock; the ball screw (6) is arranged on a bearing nut (7) through a screw nut (8); the lower end of the bearing nut (7) is fixed on a valve cover (2) through a bearing base (4); a bearing nut joint (9) is arranged on the upper end of the bearing nut (7); the upper end of the bearing nut joint (9) is connected with a switch joint (10); the lower end of the switch joint (10) is connected with the upper end of the ball screw (6); a handwheel (11) is arranged on the upper end of the switch joint (10). The ball screw of the utility model has stable operation large bearing capacity and small transmission friction coefficient, so that the switching moment of the valve is small and reaches one third of the switching moment in normal condition; meanwhile, as the ball screw has large lead, the number of the rotary cycle of the handwheel is greatly reduced when the valve is closed and opened under the condition that the switch stroke is unchanged, so as to shorten the work time and improve the work efficiency.
Description
Technical field
The utility model relates to valve, is specifically related to the ball screw valve.
Background technique
Large bore valves is when bearing high pressure, the switch force moment pole of valve is big, usually needing to be equipped with complicated worm gear, worm reduction gear could open, simultaneously, and along with the increase of reduction speed ratio, valve aperture is big more, the number of turns of opening is just many more, and the time that needs is just long, normally opens a large bore valves and need rotate nearly 100 circles of handwheel, in emergency circumstances, throttle down is not only required great effort but also consuming time.
Summary of the invention
The purpose of this utility model is: a kind of ball screw valve is provided, reduces the switch moment of valve, shorten the valve opening and closing time, realize valve quick people's opening and closing under the high-pressure work situation, increase work efficiency.
Technical solution of the present utility model is: this valve includes valve body, valve gap, valve rod and handwheel, it is characterized in that: handwheel connects valve rod by the transition transmission device, described transition transmission device is by bearing support, ball screw, bearing nut, feed screw nut, the bearing nut joint, crossover sub is formed, ball screw is connected on the valve rod by pin, ball screw is installed on the bearing nut by feed screw nut, the lower end of bearing nut is fixed on the valve gap by bearing support, the bearing nut connector is installed in the upper end of bearing nut, the upper end of bearing nut joint connects crossover sub, the lower end of crossover sub connects the ball screw upper end, and handwheel is installed in the upper end of crossover sub.
After the assembling, rotate handwheel drive crossover sub and axially rotate, drive ball-screw nut again by crossover sub and axially rotate, move down in the axial direction thereby drive ball screw by feed screw nut, the drive valve rod that moves up and down of ball screw moves up and down, thereby has controlled the opening and closing of valve.
Ball screw of the present utility model operates steadily, bearing capacity is big, the gearing friction coefficient is little, thereby cause the switch moment of valve less, can reach 1/3 under the normal condition, the helical pitch of ball screw is bigger simultaneously, under the constant situation of switching path, the number of turns that handwheel rotates when reducing valve opening greatly and closing, thus the operating time shortened, improved 3-4 working efficiency doubly.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1. valve body, 2. valve gap, 3. valve rod, 4. bearing support, 5. bearing, 6. ball screw, 7. bearing nut, 8. feed screw nut, 9. bearing nut joint, 10. crossover sub, 11. handwheels.
Embodiment
As shown in Figure 1, this valve includes valve body 1, valve gap 2, valve rod 3 and handwheel 11, it is characterized in that: handwheel 11 connects valve rod 3 by the transition transmission device, described transition transmission device is by bearing support 4, ball screw 6, bearing nut 7, feed screw nut 8, bearing nut joint 9, crossover sub 10 is formed, ball screw 6 is connected on the valve rod 3 by pin, ball screw 6 is installed on the bearing nut 7 by feed screw nut 8, the lower end of bearing nut 7 is fixed on the valve gap 2 by bearing support 4, bearing nut connector 9 is installed in the upper end of bearing nut 7, the upper end of bearing nut joint 9 connects crossover sub 10, the lower end of crossover sub 10 connects ball screw 6 upper ends, and handwheel 11 is installed in the upper end of crossover sub 10.
After the assembling, rotating handwheel 11 drive crossover subs 10 axially rotates, driving ball-screw nut 8 again by crossover sub 10 axially rotates, thereby driving ball screw 6 by feed screw nut 8 moves down in the axial direction, the drive valve rod 3 that moves up and down of ball screw 6 moves up and down, thereby has controlled the opening and closing of valve.
