Abstract
A fuel gas control switch with a pressure sensor, includes a fuel gas switch, characterized in that, the fuel gas switch is provided with a pressure sensor arranged at the lower part of the fuel gas switch, and the pressure sensor controls the on and off of the fuel gas switch through a controller, when the engine stops working, the sensor closes the fuel gas switch by a controller. The pressure sensor is connected with a digital display unit through a circuit which can realtime display the data measured by the pressure sensor. Compared with the existing technology, the invention is provided with the pressure sensor, and the speculating precision of the pressure sensor is high, the service life is long, which can adapt execrable condition, and is provided with the fuel gas protecting function, when the engine stops working, the controller controls the on and off of the fuel gas switch, to cut off the fuel gas supply and ensure the safety.
Description
Technical field
The present invention relates to the gas engine technical field, the concrete gas control switch that relates to the engine gas system.
Background technology
Gas engine is a kind of not over-emitting black exhaust, the environment protecting type engine that the discharge of harmful gases amount is very low, and along with oil crisis in the world wide and increasing environmental pollution, the demand of the gas engine of this environment-friendly type is more and more urgent.
The gas burning system that starts generally has burnt gas switch and gaseous-pressure table, but burnt gas switch and Pressure gauge are generally two parts, and Pressure gauge to be generally pointer be Pressure gauge, this Pressure gauge is easy to damage in the process of using.
Summary of the invention
Technical problem to be solved by this invention is, a kind of gas control switch that has pressure sensor is provided.
In order to address the above problem, technical scheme of the present invention is such:
A kind of gas control switch that has pressure sensor, comprise the burnt gas switch body, it is characterized in that, one pressure sensor is set on the burnt gas switch body, described pressure sensor is arranged on the downstream of burnt gas switch, the switching that pressure sensor is lighted switch by controller control, when engine quit work, sensor cut out burnt gas switch by controller.
Described pressure sensor connects a numeric display unit by circuit, and described numeric display unit shows data that pressure sensor is surveyed in real time.
Beneficial effect; compared with prior art; the present invention has pressure sensor, and described pressure sensor supposition precision height, and service time is long; can adapt to than harsh conditions; and have the combustion gas defencive function, when engine quit work, controller control burnt gas switch was closed; cut off gas supply, guarantee security of system.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 has the structured flowchart of the gas control switch of pressure sensor for the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, a kind of gas control switch that has pressure sensor, the one end connects air accumulator, comprising the burnt gas switch body, one pressure sensor is set on the burnt gas switch body, and described pressure sensor is arranged on the downstream of burnt gas switch, the switching that pressure sensor is lighted switch by controller control, when engine quit work, sensor cut out burnt gas switch by controller.
Described pressure sensor connects a numeric display unit by circuit, and described numeric display unit shows data that pressure sensor is surveyed in real time.
Compared with prior art; the present invention has pressure sensor; and described pressure sensor is inferred the precision height; service time is long, can adapt to than harsh conditions, and have the combustion gas defencive function; when engine quits work; controller control burnt gas switch is closed, and cuts off gas supply, guarantees security of system.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
