Abstract
The utility model discloses an external butterfly valve of a blowing and sweeping device, and belongs to cleaning and maintenance technology of the butterfly valve. The butterfly valve of the blowing and sweeping device solves the problem that impurities remaining in a valve in the prior art can cause damages to the butterfly valve when the butterfly valve is closed. The external butterfly valve of the blowing and sweeping device comprises a valve body (1), and a rotating valve core (2) connected with the valve body (1) through a central rotating shaft (3). The external butterfly valve of the blowing and sweeping device is characterized in that the external portion of the valve body (1) is provided with the blowing and sweeping device which stretches into the valve body (1). The external butterfly valve of the blowing and sweeping device has the advantages of being simple in structure, convenient to operate, capable of guaranteeing normal use of the butterfly valve, achieving full use of resources, and effectively reducing cleaning and maintenance cost.
Description
Technical field
The utility model relates to a kind of blowing cleaner, specifically, is a kind of blowing cleaner external batterfly valve.
Background technique
In the existing technology; Butterfly valve is applicable in the engineering systems such as producer, coal gas, rock gas, LPG, town gas, cold and hot air, chemical industry smelting and generation environment-friendly and carries on the pipeline of various corrosivity, non-corrosive fluids medium, is used to regulate and block flowing of medium.Because some impurity that contain in the flowing medium can residual closure places that are attached to valve inner and rotational valve core, butterfly valve rotational valve core when closing is mutually airtight with valve body, can cause damage influence its working life to it as if there being impurity to be mingled with therebetween then.The user needs voluntarily it to be cleared up and safeguard, resource has been caused great waste, has increased user's burden.
The model utility content
The purpose of the utility model is to provide a kind of blowing cleaner external batterfly valve; Solve the needs that exist in the existing technology and voluntarily its cleaning is caused the problem of wasting and having increased burden for users with maintenance, to resource; Guaranteeing under the normal prerequisite of using of butterfly valve; The realization resources effective is utilized, and reduces user's burden.
To achieve these goals, the technological scheme of the utility model employing is following:
The blowing cleaner external batterfly valve comprises valve body, and through the rotational valve core that shaft links to each other with valve body, said valve body outside is provided with and extends into its inner blowing cleaner.
Further, said blowing cleaner comprises that an end stretches into the connecting tube of valve inner, and the flange plate that is installed in this connecting tube the other end.
Again further, the quantity of said blowing cleaner is more than one.
Further, the caliber of said connecting tube is 20mm to 100mm.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model is simple in structure, owing to increased the blowing cleaner that penetrates valve body in the butterfly valve body outside, it can normally be moved, can also purge its inside simultaneously, thus can efficent use of resources, avoid the wasting of resources, reduce user's burden;
(2) the utility model has been realized purging through blowing cleaner to dish valve inside, thereby has avoided the dish valve to receive the influence of impurity and damage, and has guaranteed the working life of dish valve;
(3) the utility model has been realized the automatic purging of impurity, has not only saved a large amount of manpower and materials, and has improved purging efficient;
(4) the utility model cost performance is high, is fit to very much large-scale promotion application.
