Description

[Technical field]

[0001] The utility model relates to the technical field of pneumatic conveying, in particular to the technical field of a novel pneumatic plug-in valve control mode with an automatic purge function. [Background technology]

[0002] In the process of container feeding, pneumatic gate valve is often used as the control valve for feeding. The conventional control mode is: the solenoid valve in the local solenoid valve box controls the compressed air in the outlet copper tube to enter the cylinder of the pneumatic gate valve. When the cylinder is fed with air, the valve opens, and when the cylinder is exhausted, the valve closes. During the process of container loading, part of the falling material will fall into the internal cavity valve of the pneumatic gate valve. Some materials with bad properties, such as wet and sticky materials, will even accumulate in the valve cavity, causing the pneumatic gate valve to be unable to open or close completely. The valve is not in place, which will cause many serious problems such as too much falling material in the warehouse pump. [Contents of the utility model]

[0003] The purpose of the utility model is to solve the problems in the prior art and propose a new pneumatic gate valve control mode with automatic purge function, which can automatically purge the internal valve cavity of the pneumatic gate valve, and the purge time is controllable and energy-saving. The purge is carried out by using conveying gas with high pressure and clean purge, which effectively prevents the valve from getting stuck or not in place. The engineering effect is obvious and can bring huge benefits.

[0004] To achieve the above-mentioned purpose, the utility model proposes a new type of pneumatic gate valve control mode with automatic purge function, including a compressed air main pipe, a pneumatic butterfly valve body, an air-guiding plastic pipe, a pneumatic gate valve body, a valve cavity, a blanking pipe, a material container, a pneumatic gate valve cylinder, an outlet copper pipe, an on-site solenoid valve box and a pneumatic butterfly valve cylinder, the compressed air main pipe is connected with the air-guiding plastic pipe through the pneumatic butterfly valve body, the valve cavity of the pneumatic gate valve body is connected and arranged between the blanking pipe and the material container, the end of the air-guiding plastic pipe is connected with the valve cavity of the pneumatic gate valve body, a pneumatic gate valve cylinder is arranged on the outside of the pneumatic gate valve body, the pneumatic gate valve cylinder is connected with the on-site solenoid valve box through the outlet copper pipe, a pneumatic butterfly valve cylinder is arranged on the outside of the pneumatic butterfly valve body, and the on-site solenoid valve box is connected with the pneumatic butterfly valve cylinder through the outlet copper pipe.

[0005] Preferably, a compressed air source connected to the outlet copper pipe is provided in the on-site solenoid valve box.

[0006] Preferably, the pneumatic butterfly valve cylinder drives the pneumatic butterfly valve body to open and close, and the pneumatic gate valve cylinder drives the pneumatic gate valve body to open and close.

[0007] Preferably, there are a plurality of the air-conducting plastic tubes, and the ends of the air-conducting plastic tubes are evenly arranged around the valve cavity.

[0008] Preferably, a check valve is provided at the connecting portion between the air-conducting plastic tube and the valve cavity.

[0009] Preferably, the outlet copper tube comprises an air inlet copper tube and an air exhaust copper tube, and the local solenoid valve box is connected to the pneumatic butterfly valve cylinder and the pneumatic gate valve cylinder respectively through the outlet copper tube.

[0010] The beneficial effects of the utility model: the utility model combines the compressed air main pipe, the pneumatic butterfly valve body, the air-conducting plastic pipe, the pneumatic gate valve body, the valve cavity, the drop pipe, the material container, the pneumatic gate valve cylinder, the outlet copper pipe, the local electromagnetic valve box and the pneumatic butterfly valve cylinder together, and after experimental optimization, the automatic purge function does not require repeated manual labor, which greatly saves manpower and material costs. During purge, the instrument air used to open the local electromagnetic valve box is used to open the pneumatic butterfly valve body. After the pneumatic butterfly valve body is opened, the air from the compressed air main pipe enters the valve cavity through the air-conducting plastic pipe for purge. When the pneumatic gate valve body is closed, the purge ends. Therefore, the purge is not often opened and the time is short. Controllable and energy-saving, using compressed air for purging with high pressure and clean purge. Using the local solenoid valve box to use air to open the pneumatic gate valve body and at the same time open the pneumatic butterfly valve body of compressed air, and then use compressed air for purging. This has little effect on the local solenoid valve box. The time of opening the pneumatic gate valve body is used to purge the valve. The purge time is controllable and energy-saving. Now there are thousands of feed valves and switching valves in a large number of engineering projects that are stuck or out of place, which brings great practical difficulties to the engineering projects. These valves need to be replaced or modified. After using this technical transformation, not only the performance is guaranteed, but also it can bring at least hundreds of millions of profits to the company every year.

[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

A pneumatic butterfly valve cylinder 11 is arranged on the outside of the pneumatic butterfly valve body 2, the local solenoid valve box 10 is connected with the pneumatic butterfly valve cylinder 11 through the outlet copper tube 9, a compressed air source connected with the outlet copper tube 9 is arranged in the local solenoid valve box 10, the pneumatic butterfly valve cylinder 11 drives the pneumatic butterfly valve body 2 to open and close, the pneumatic gate valve cylinder 8 drives the pneumatic gate valve body 4 to open and close, there are multiple air-guiding plastic tubes 3, the ends of the air-guiding plastic tubes 3 are evenly arranged around the valve cavity 5, a check valve 12 is arranged at the connecting portion between the air-guiding plastic tube 3 and the valve cavity 5, the outlet copper tube 9 includes an air inlet copper tube and an exhaust copper tube, and the local solenoid valve box 10 is respectively connected with the pneumatic butterfly valve cylinder 11 and the pneumatic gate valve cylinder 8 through the outlet copper tube 9.

[0015] The working process of the utility model is as follows: air is supplied through the compressed air mother pipe 1, and then the valve cavity 5 inside the pneumatic gate valve body 4 is purged through the pneumatic butterfly valve body 2 and the air-conducting plastic tube 3, so that the materials deposited inside the valve cavity 5 are completely purged, ensuring that the valve cavity 5 can be purged clean and the valve can be completely in place. When the pneumatic gate valve body 4 needs to be opened, the pneumatic butterfly valve body 2 is opened at the same time for purging; when the pneumatic gate valve body 4 is closed, the pneumatic butterfly valve body 2 is closed, and the purging stops at the same time, so the purging is not always open, which is very energy-saving. The compressed air is used as the purging gas, the pressure is high, and the purging is clean.

When the pneumatic gate valve body 4 is closed, the purge is terminated, so the purge is not often opened. The time is controllable and energy-saving. Compressed air is used for purging with high pressure and clean purge. The local solenoid valve box 10 is used to open the pneumatic plug valve body 4 while opening the pneumatic butterfly valve body 2 of compressed air, and then the compressed air is used for purging. This has little effect on the local solenoid valve box 10. The time of opening the pneumatic plug valve body 4 is used to purge the valve. The purging time is controllable and energy-saving.

These valves need to be replaced or modified. After using this technical transformation, not only the performance is guaranteed, but also it can bring at least hundreds of millions of profits to the company every year.
