Description
Technical field
The utility model belongs to butterfly valve processing technique field, particularly relates to a kind of butterfly valve air-tightness measuring equipment.
Background technology
Butterfly valve is flap valve again, is the simple variable valve of a kind of structure, also can be used for the switch control rule of low pressure pipeline medium simultaneously.Butterfly valve refers to that closing member (flap or butterfly plate) is disk, rotates a kind of valve reaching open and close around valve shaft, and on pipeline, main rising is cut off and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, rotates in valve seat around the axis of himself, thus reaches the object opening and closing or regulate.Butterfly valve is applicable to carry on the pipeline of various corrosivity, non-corrosive fluids medium, for regulating and block the flowing of medium in the engineering systems such as producer, coal gas, rock gas, liquefied petroleum gas (LPG), town gas, air, chemical industry smelting and generation environment-friendly.
How effective butterfly valve seat air tightness test is the only stage which must be passed by that it dispatches from the factory, therefore, carry out airtightness measurement and become a puzzlement difficult problem in the industry butterfly valve.
Summary of the invention
The purpose of this utility model is to provide the butterfly valve air-tightness measuring equipment that a kind of structure is simple, easy to use, measurement efficiency is high, measurement effect is good, utilizes problems of the prior art to solve.
