Abstract
The utility model relates to a manual operating mechanism for a valve electric actuator. The manual operating mechanism for the valve electric actuator comprises a valve rod cover, a hand wheel and a hand wheel assembly and is characterized in that the hand wheel comprises a base and handle grips, wherein the handle grips are solid steels welded on the base, and an inclination angle is formed between the hand grips and the horizontal plane; the base of the hand wheel is connected with the hand wheel assembly by bolts; and the valve rod cover is connected with the base of the hand wheel by bolts. By adopting the structure, the problem that a valve rod rusts due to the untight sealing of the threaded connection of the conventional valve rod cover is effectively solved; in the novel hand wheel, the conventional welding form of pipes and plates is changed into a form that the handle grips are solid steels assembled and welded on the cast steel base, so that the working reliability is improved; and a certain angle is formed between the handle grips and the horizontal plane, so that the problem that hand power utilization rate is low when an operator operates the manual operating mechanism is effectively solved, most of the hand power can be applied to a rotating torque, the ergonomic requirements are met, and the working efficiency is improved to a certain extent.
Description
Technical field
The utility model belongs to the electric device for valve technical field, particularly relates to a kind of electric device for valve manual-operating mechanism.
Background technique
At present, electric device for valve is that a kind of and valve are used the industrial machinery of the height electromechanical integration of control valve opening and closing.The operation that when debugging or outage, requires manually-operable to come control valve.Therefore, manual-operating mechanism is the indispensable important component part of electric device for valve.So the design of manual-operating mechanism should be considered from aspects such as its reliability, ergonomic.
Electric device for valve manual-operating mechanism in the known technology has the mode of two kinds of driving torques.A kind of is that general common direct and output shaft is formed bindiny mechanism, and man-operated mechanism directly drives the output shaft rotation in the time of manually, thus the keying of control valve.The electric device for valve that the common controlling torque of this mode is less.Another kind of mode is the control of carrying out valve on the output shaft through being delivered to after the gear graduation, and this kind mode is suitable for controlling the electric device for valve of big torque.The handwheel section bar serves as main being welded with tubing and sheet material in the existing manual portion cover, if the welding imprecision can cause moisture to get in the hollow tubular in welding process, causes tubing corrosion gradually internally.Because detent torque is bigger, the instantaneous torque that causes to manual operating device is also bigger, causes the damage of manual-operating mechanism easily when carrying out valve event with manual-operating mechanism under certain conditions.Existing valve rod cover directly connects with the form that is threaded that handwheel 2 is connected with handwheel combination 3 usefulness screws 4 among (as shown in Figure 2) figure when being connected with operated by handwheel mechanism, valve rod cover 1 is through being threaded onto on the handwheel combination 3.Easy like this when causing electric device for valve to use out of doors liquid infiltrate along thread pitch and cause valve rod to get rusty.The handle of tradition handwheel is parallel with horizontal plane, and the power that the operator is exported when the operation handwheel does not all produce the efficient reduction that torque makes the operator.
Summary of the invention
The utility model provides a kind of reliability high for solving the technical problem that exists in the known technology, and ergonomic is specially adapted to export the electric device for valve manual-operating mechanism of less torque.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of electric device for valve manual-operating mechanism; Comprise valve rod cover, handwheel and handwheel combination; It is characterized in that: said handwheel comprises base and handle, and said handle adopts solid steel to be welded on the base, and becomes a tilt angle with horizontal plane; The base of said handwheel is through bolt connection hand wheel combination, and said valve rod cover connects the base of handwheel through bolt.
The utility model can also adopt following technical measures:
The size at said handle tilt angle is 20 °.
Advantage and the good effect that the utlity model has are: because the utility model adopt to be gone up structure, solved the existing valve rod cover poorly sealed close problem that causes valve rod to get rusty of form that is threaded.Novel handwheel changes the Type of Welding of former tubing and sheet material into solid steel and the assembling of cast steel base and welds, and has improved the reliability of its work.The utility model handle and horizontal plane have a certain degree; This kind method has effectively been improved operator's low problem of manual force utilization ratio when the operator pneumatic operating mechanism; Can most of manual force be used for moment of rotation, ergonomic has improved working efficiency to a certain extent.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the known technology structural representation.
Among the figure: 1, valve rod cover; 2, handwheel; 2-1, base; 2-2, handle; 3, handwheel combination; 4, bolt; 5, bolt.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of electric device for valve manual-operating mechanism comprises valve rod cover 1, handwheel 2 and handwheel combination 3; Said handwheel comprises base 2-1 and handle 2-2; Said handle 2-2 adopts solid steel to be welded on the base 2-1, and becomes a tilt angle with horizontal plane, and said tilt angle is 20 °; This kind method has effectively been improved operator's low problem of manual force utilization ratio when the operator pneumatic operating mechanism; Can most of manual force be used for moment of rotation, ergonomic has improved working efficiency to a certain extent.The base 2-1 of said handwheel 2 is through bolt 4 connection hand wheels combination 3, and said valve rod cover 1 connects the base 2-1 of handwheels 2 through bolt 5, the effective so existing valve rod cover poorly sealed close problem that causes valve rod to get rusty of form that is threaded that solved.
