Abstract
The utility model belongs to the technical field of valves of mechanical products, in particular to a control device of a valve. The control device of the valve comprises a handle, a dustproof ring, an outer cover, a transmission part, a spring and a bolt. The control device of the valve is characterized in that the outer cover is connected with the valve body, and the dustproof ring is arranged in a position where the handle and the outer cover are matched. The transmission part is arranged between the handle and the valve rod and clutch operation on the handle and the valve rod is performed through the spring. The control device of the valve has the advantages that due to the fact that the dustproof structure is adopted by the device, the valve rod can be effectively protected, and the service life of the valve rod is prolonged. In addition, by the adoption of the clutch structure, even if under the situations of bumping and the like, malfunctions can not be caused, and safety and reliability in using the valve are improved.
Description
Technical field
The utility model belongs to the machinery product valve technology field, relates in particular to the Effector of valve.
Background technique
Valve is used for controlling direction, pressure, the flow of fluid, is to be widely used in fluid system and one of very important parts, and to its operation, must be therefore convenient, safe and reliable.Existing manually-operated gate is general direct to be operated the handle that is connected on valve rod, usually establish polygonal in the middle of the handle or the profile of tooth through hole matches with the set tenon in valve rod end, this structure has the following disadvantages: often be subject to serious corrosion due to valve rod and handle 1., strengthened the operation torsion of valve, make troubles to valve operation, and to considerable influence is also arranged its working life; 2. because handle is not established protective gear, easily valve is carried out misoperation in the situation such as collide with, thereby bring unnecessary loss.
Summary of the invention
The purpose of this utility model is the Effector that a kind of valve is provided in order to address the above problem.
Scheme of the present utility model is achieved in that a kind of Effector of valve, comprise handle, dust ring, outer cover, driving component, spring and bolt, it is characterized in that: outer cover is connected with valve body, handle and outer cover cooperation place are provided with dust ring, are provided with driving component between handle and valve rod and by spring, it are carried out the clutch operation; Described outer cover is the cylinder that an end is provided with flange, and endoporus is step-like through hole, at the little endoporus place of the other end, is provided with the dust ring mounting groove, and large end radially is provided with little air hole; Be provided with cylinder boss in the middle of described handle, cylindrical matches with the little endoporus of outer cover, and at raised head face, is provided with hole and tapped hole; Described driving component is step-like cylinder made of copper, and large end matches with the large endoporus of outer cover, and small end matches with the handle endoporus, and being provided with dentation or polygonal endoporus, shape size matches with the valve rod tenon, and in aperture, is provided with guiding, and with valve rod end formation line, contact, to reduce friction.
The beneficial effects of the utility model are: because said apparatus has adopted dustproof construction; make valve rod obtain effective protection, improve its working life, and the employing of clutch structure; even also unlikely generation misoperation in the situation such as collide with, improve the safety reliability that valve uses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, handle, 2, dust ring, 3, driving component, 4, valve rod, 5, outer cover, 6, bolt, 7, spring, 8, valve body.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
As shown in Figure 1, valve body 8 is connected with outer cover 5, thereby be provided with dust ring 2 between outer cover 5 and handle 1, has formed a confined space, has effectively stoped extraneous dust and pollution medium to enter inside; Depression of handle 1 overcomes the resistance of spring 7, can make driving component 3 contact with valve rod 4, and rotation gently, make with profile of tooth or the polygonal tenon of valve rod end and be meshed simultaneously, is pressed into simultaneously and makes it be in interlocking pattern, can operate valve; Decontrol handle 1,, due to the effect of spring 7, can make driving component 3 and valve rod 4 be in separated state, thereby avoid the misoperation that produces in the situation such as collide with.In this process, the set air hole of outer cover 5 has guaranteed that also air pressure inside communicates with atmospheric pressure, and unlikely generation damping phenomena, make operating state more flexible.
During assembling, outer cover 5 is equipped with dust ring 2, and handle 1 is packed into, and outer cover 5 is rear to be connected with driving component 3 use bolts 6, after spring 7 is put into outer cover 5 endoporus, then with valve body 8, is connected.
Claims (4)
