Abstract
The utility model provides a blowing and sweeping type pneumatic knife-shaped sluice valve, which comprises a pneumatic knife-shaped sluice valve body, and is characterized by also comprising a gas blowing and sweeping pipeline connected with an external high-pressure gas source; the gas blowing and sweeping pipeline is annularly arranged at the surrounding of a valve cavity at the lower part of the pneumatic knife-shaped sluice valve and is provided with a plurality of branch pipes which are communicated with the valve cavity; the gas inlet end of the gas blowing and sweeping pipeline is provided with a blowing and sweeping control valve. The blowing and sweeping type pneumatic knife-shaped sluice valve can clean the deposits in the valve cavity clean as a pin by only being connected with the external gas source and starting an air compressor under the condition of not dismounting the pipelines, thus greatly reducing the maintenance cost, greatly improving the labor productivity, and not affecting the continuous use of the pipelines.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of Pneumatic knife-shape gate valve of blowing and sweeping type.
Background technique
The knife-shape gate valve of prior art generally is installed in the gas powder medium pipeline that contains solid particle.Solid particle is easy to be trapped in the valve body chamber, and after after a while, the solid particle of deposition will have influence on the sealing of valve, serious even moving up and down of having influence on flashboard and the proper functioning that jeopardizes gate valve.
For normal use, valve must regularly carry out the body cavity cleaning, gets rid of sediments, is very much trouble.The installation position that has is not easy to dismounting valve again, and therefore, this bad sediments is that engineering is brought very big trouble.
The model utility content
The purpose of this utility model exactly in order to address the above problem, provides a kind of Pneumatic knife-shape gate valve of blowing and sweeping type.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of Pneumatic knife-shape gate valve of blowing and sweeping type, comprise the Pneumatic knife-shape gate valve body, be characterized in: also comprise the gas purging pipeline that can link to each other with the external high pressure source of the gas, this gas purging pipeline ring be located at Pneumatic knife-shape gate valve bottom valve pocket around and be provided with a plurality of arms and be communicated with valve pocket, be provided with the purging control valve at the suction port end of gas purging pipeline.
The described a plurality of arms that are communicated with valve pocket are communicated with valve pocket from the different parts of the sealing groove of valve pocket respectively.
The described a plurality of arms that are communicated with valve pocket comprise an arm that is communicated with valve pocket under the valve pocket.
The described a plurality of arms that are communicated with valve pocket are threaded with valve chamber respectively.
Described purging control valve is a motor-operated control valve.
Described purging control valve is a hand control valve.
The utility model Pneumatic knife-shape gate valve of blowing and sweeping type makes it compared with prior art owing to adopted above technological scheme, have following advantage and and characteristics:
1, be widely used:
Can be applied in widely in the industrial pipeline, especially be suitable for important pipeline position that cannot the regular dismounting cleaning with power station, metallurgy, coal industry.
2, easy for installation:
The gas purging pipeline is located at outward around the valve body chamber, and it is little to take up room, and open operation is independent of valve opening and closing operation control, directly is connected with outer source of the gas.
3, purge advantage:
Under the situation of detaching pipelines not, as long as connect external air source (generally being to link to each other) with High-Pressure Compressor, start air compressor, just can clear up the endoceliac sediments of valve completely, reduced maintenance cost greatly, improve labour productivity greatly, do not influenced the continuous use of pipeline.
Description of drawings
Fig. 1 is the structural representation of facing of the utility model Pneumatic knife-shape gate valve of blowing and sweeping type;
Fig. 2 is the side-looking structural representation of the utility model Pneumatic knife-shape gate valve of blowing and sweeping type.
Embodiment
Referring to Fig. 1, Fig. 2, Pneumatic knife-shape gate valve of blowing and sweeping type of the present utility model comprises a Pneumatic knife-shape gate valve body 1 and a gas purging pipeline 2 that can link to each other with the external high pressure source of the gas.
Pneumatic knife-shape gate valve body 1 is provided with cylinder 11, pressure regulator valve 12, solenoid valve selector valve 13, control box 14 and flashboard 15.
The working principle of Pneumatic knife-shape gate valve of blowing and sweeping type of the present utility model is:
Normal running: actuating device is a cylinder, and open-shut device is a flashboard.Cylinder promotes piston by receiving the bleed pressure air, and piston passes through piston rod push-and-pull flashboard, thereby reaches the operation that pilot line is logical and close.The movement velocity of flashboard, just the opening and closing time of valve is adjusted bleed pressure by pressure regulator valve and is controlled.The moving direction of piston is controlled by solenoid directional control valve.
Purge operations: the gas purging pipeline is connected with external air source, opens and purge control valve (manual or electronic), gas enters the valve body cavity by the gas purging pipeline, and valve is forced to purge.Purge if carry out brute force, be connected into High-Pressure Compressor and get final product, programmed sequence of operations is constant.
