Abstract
In order to solve problems of the prior art, a kind of laborsaving valve handle of the utility model design, comprises handwheel body, handwheel body is designed with valve rod hole and hand wheel handle, described valve rod hole design is in handwheel body central position, and the described valve rod hole center of circle is on hand wheel handle axis elongation line; Hand wheel handle is designed with 3, and hand wheel handle is evenly distributed on handwheel body; Hand wheel handle is made up of hand wheel handle termination and handwheel arbor, handwheel arbor and hand wheel handle termination are for removably connecting, for arc surface transition is connected between handwheel arbor with hand wheel handle termination, described handwheel arbor near hand wheel handle termination end outer surface for non slip surface designs, this structural design is simple, operate more convenient, defect of the prior art can well be overcome.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of laborsaving valve handle.
Background technique
Valve is the controlling component in fluid delivery system, for the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various, and valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium, the valve adopting manual form to open and close generally all can be provided with handwheel, handwheel is round structure, its principle utilizes handwheel radius as the arm of force, strengthen driving torque, therefore under equal torsion, handwheel radius is larger, moment of torsion is larger, existing handwheel, its circumference is generally smooth curve, or comprise the moulding that some increase frictional force, but, the handwheel of this structure is adopted all to need to be realized by the frictional force between hand and handwheel in unlatching or closing operation, when valve is tighter, when needing to rotate compared with high pulling torque, free-hand rotation is often extremely required great effort, cause operator's labor intensity larger.
Summary of the invention
In order to solve problems of the prior art, a kind of laborsaving valve handle of the utility model design, this structural design is simple, operates more convenient, can well overcome defect of the prior art.
A kind of laborsaving valve handle, comprises handwheel body, handwheel body is designed with valve rod hole and hand wheel handle, and described valve rod hole design is in handwheel body central position, and the described valve rod hole center of circle is on hand wheel handle axis elongation line; Hand wheel handle is designed with 3, and hand wheel handle is evenly distributed on handwheel body; Hand wheel handle is made up of hand wheel handle termination and handwheel arbor, handwheel arbor and hand wheel handle termination for removably connecting, for arc surface transition is connected between handwheel arbor with hand wheel handle termination, described handwheel arbor near hand wheel handle termination end outer surface for non slip surface designs.
Described hand wheel handle termination is designed for spherical structure.
Described handwheel arbor is designed with clamping platform near handle wheel tip position, and this clamping platform is designed with clamping groove, hand wheel handle termination is designed with the clamping matched protruding.
On described handwheel arbor, non slip surface is designed to frosting structure.
The beneficial effects of the utility model are the valve handles designed by said structure, when opening and closing valve, only need with hand push handwheel handle just passable, do not need to hold handwheel and realize valve opening and closing operation by frictional force to each other, more laborsaving, when valve opening with when closing more painstaking, hand wheel handle termination can also be taken off, on hand wheel handle, the steel pipe of sheathed corresponding size increases the arm of force, under the effect of identical unlatching moment, need the power of unlatching just little a lot, realize labour-saving effect; Simultaneously because the non slip surface structural design in handle shaft, when operation, also can not drench because of hand perspiration or hand wheel handle problems such as occurring operating difficulties; For arc surface transition is connected and hand wheel handle termination is that the potential safety hazard that spherical structure is designed to operator has done good prevention between hand wheel handle with hand wheel handle termination, there is no sharp-pointed end face and projection, the place that product and operator can touch all adopts arc surface transition, causes the hidden danger of personal injury when operator can well be prevented to collide with; This product specification is simple, and worth consumers in general easy to use use popularization.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, valve rod hole; 2, hand wheel handle; 3, handwheel arbor; 4, hand wheel handle termination; Clamping platform; 6, clamping groove.
Embodiment
As shown in Figure 1, a kind of laborsaving valve handle, comprises handwheel body, handwheel body is designed with valve rod hole 1 and hand wheel handle 2, and described valve rod hole 1 designs in handwheel body central position, and described valve rod hole 1 center of circle is on hand wheel handle 2 axis elongation line; Hand wheel handle 2 is designed with 3, is evenly distributed on handwheel body; Hand wheel handle 2 is made up of hand wheel handle termination 4 and handwheel arbor 3, handwheel arbor 3 and hand wheel handle termination 4 are for removably connecting, for arc surface transition is connected between handwheel arbor 3 with hand wheel handle termination 4, described handwheel arbor 3 near hand wheel handle termination 4 end outer surface for non slip surface designs.
Described hand wheel handle termination 4 is designed for spherical structure.
Described handwheel arbor 3 has clamping platform 5 near handle wheel termination 4 Position Design, and this clamping platform 5 is designed with clamping groove 6, hand wheel handle termination 4 is designed with the clamping matched protruding.
On described handwheel arbor 3, non slip surface is designed to frosting structure.
It should be noted that above-mentioned embodiment just provides a specific embodiment for organization plan of the present utility model; in this embodiment, limited range can not as the foundation limiting this utility model protection scope, and any equal similar designs based on this principle of invention all belongs to protection domain of the present utility model.
