Problems solved by technology
[0004] The object of the present invention is to provide an automatic gas intake speed control valve and its control method, which can solve the problem that although the existing control valves of this type can control the gas intake speed, they lack The internal structure of the control valve is automatically protected when the speed is too fast and the air pressure is too high, so that the control valve is easy to be damaged under extreme conditions such as too fast intake speed and too high air pressure, and the structure of leak-proof protection is ensured, so that There are certain safety hazards caused by gas leakage

Embodiment Construction
[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0033] see Figure 1-7As shown, an automatic gas intake speed control valve includes a valve body 1, a protection mechanism 19 installed inside the valve body 1, and an anti-leakage mechanism 21. The two ends of the valve body 1 are respectively provided with an inlet port 2 and an exhaust port 3. , the outer rings of the inlet end 2 and the exhaust end 3 are equipped with a butt sleeve 6 for gas pipeline connection, the middle part of the exhaust end 3 is provided with an air outlet 8, and the side wall of the valve body 1...

The invention discloses a gas inlet speed automatic control valve. The automatic control valve solve the problem that when the existing control valve is in use, the air inlet speed of the fuel gas canbe controlled, but the structure for automatically protecting the internal structure of the control valve when the gas inlet speed of the fuel gas is too fast and the air pressure is too large is lacked, so that the situation that the control valve is damaged under the limit conditions that the air inlet speed is too fast and the air pressure is too high, the leakage-proof protection structure isensured, and the problem of potential safety hazards caused by gas leakage is solved. The gas inlet speed automatic control valve comprises a valve body, a protection mechanism and an anti-leakage mechanism, the protection mechanism and the leak-proof mechanism are arranged in the valve body; the two ends of the valve body are respectively provided with an air inlet end and an air outlet end; theair inlet end, the outer ring of the exhaust end is provided with butt joint sleeves for butt joint of the fuel gas pipeline, an air outlet is formed in the middle of the exhaust end, a display screen mounting groove and a PLC controller mounting groove are formed in the side wall of the valve body.
Description
technical field [0001] The invention relates to the field of gas control valves, in particular to an automatic gas intake speed control valve and a control method thereof. Background technique [0002] The gas intake speed control valve is a valve used to control the gas intake speed, which is a kind of valve. However, the existing control valves still have certain defects in use. Although they can control the gas intake speed, However, it lacks a structure to automatically protect the internal structure of the control valve when the gas intake speed is too fast and the air pressure is too high, so it is easy to damage the control valve under extreme conditions such as too fast intake speed and high air pressure, and ensure Leak-proof protection structure, so there are certain safety hazards caused by gas leakage. [0003] The patent with the publication number CN202580065U discloses a gas control valve. Compared with the present application, the gas control valve provided ...
