Abstract
The utility model provides a motion prevention structure of a valve rod of a butterfly valve, relates to the technical field of fluid control, and aims at solving the technical problems that an existing butterfly valve is not tight in sealing and prone to leakage, and a valve rod of the existing butterfly valve motions. According to the motion prevention structure of the valve rod of the butterfly valve, a limiting groove is formed in the periphery of the tail end portion of the valve rod (4), split collars (3) are arranged in the limiting groove, a friction pad (2) is arranged on the split collars (3), and an adjusting pad (5) is arranged on the tail end face of the valve rod (4).
Description
Technical field
The utility model patent relates to the fluid control technology field, particularly a kind of anti-play structure of butterfly valve valve rod that is used for petroleum chemical industry.
Background technique
The existing employed butterfly valve of petroleum chemical industry does not have the anti-play structure of valve rod usually, therefore be prone to because the unstable working condition that the valve rod play causes, poorly sealed, be prone to technical problem such as leakage phenomenon.
Summary of the invention
The utility model be intended to solve existing butterfly valve exist the valve rod play, poorly sealed, be prone to technical problem such as leakage, so that a kind of anti-play structure of butterfly valve valve rod with the anti-play structure of valve rod, stable working state, good seal to be provided.
The purpose of this utility model is achieved through the following technical solutions.
Butterfly valve valve rod of the present utility model is prevented the play structure, and valve rod 4 tail end peripheries are provided with restraining groove, installing divided ring 3 in the restraining groove, and divided ring 3 tops are equiped with friction pad 2, and valve rod 4 breech faces are equiped with spacer 5.
The beneficial effect of the anti-play structure of the utility model butterfly valve valve rod: can prevent effectively that valve rod play, stable working state, sealability are reliable.
Description of drawings
Fig. 1 the utility model structural representation
The number in the figure explanation:
1 valve body, 2 friction pads, 3 divided rings, 4 valve rods, 5 spacers, 6 end caps
Embodiment
The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1, are illustrated by following mode of execution.
As accompanying drawing 1-2, butterfly valve valve rod of the present utility model is prevented the play structure, and valve rod 4 tail end peripheries are provided with restraining groove, installing divided ring 3 in the restraining groove, and divided ring 3 tops are equiped with friction pad 2, and valve rod 4 breech faces are equiped with spacer 5.
Working principle of the present utility model is as follows:
Because valve rod 4 afterbodys are processed with restraining groove, and install divided ring 3 additional, install friction pad 2 additional on divided ring 3 tops, thereby can limit to valve rod head play;
Owing to add spacer 5 at valve rod 4 afterbodys, thereby can limit to valve rod afterbody play.
In sum, butterfly valve valve rod of the present utility model is prevented the play structure, has effectively to prevent many technological merits such as valve rod play, stable working state, sealability be reliable.
