Abstract
The utility model discloses a gas valve based on the control of a single chip microprocessor. The gas valve comprises a straight-through pipe, a valve, a rotating bolt and a valve handle. The gas valve is characterized in that the rotating bolt is also fixedly provided with a control handle through a second nut, the tail end of the control handle is provided with a hole corresponding to the rotating bolt, and the upper end of the control handle extends in the direction of the valve handle. The gas valve also comprises a control module, wherein the control module is provided with a gas detector and a single chip microprocessor control chip, an output end of the gas detector is connected with an input end of the single chip microprocessor control chip, an output end of the single chip microprocessor control chip is connected with an input end of a hydraulic cylinder, a hydraulic rod of the hydraulic cylinder is connected with a connecting rod, and the front end of the connecting rod is provided with a lower slope. The gas valve is simple in structure; and once a gas leakage phenomenon is detected by the gas detector, the single chip microprocessor control chip can automatically control the hydraulic cylinder and the connecting rod to work, the connecting rod can push the control handle to close the gas valve, and therefore, the safety potential danger caused by the gas leakage can be avoided, convenience in use can be realized, and the universality is strong.
Description
Technical field
The utility model relates to a kind of based on monolithic processor controlled gas valve.
Background technique
In present family, natural gas line is very common facility.In order effectively to control the open and close of rock gas, all be provided with gas valve on the natural gas line of family, common gas valve is generally handle type, by manually push away, handle, realize the open and close function to rock gas.In the natural gas motorcar process, the phenomenon that often can leak air is brought huge potential safety hazard.Especially when the family no one, gas leakage often can not in time be realized, thereby is bred disaster.
The model utility content
The purpose of this utility model is to provide a kind of based on monolithic processor controlled gas valve.
to achieve these goals, by the following technical solutions, a kind of based on monolithic processor controlled gas valve, comprise straight-through tube, valve is arranged in straight-through tube, has swivel bolt on valve, be fixed with valve handle by the first nut on this swivel bolt, it is characterized in that: also be fixed with control handle by the second nut on described swivel bolt, the end of this control handle has the hole that adapts with swivel bolt, described gas valve also comprises a control module, have gas detecting instrument and singlechip control chip on this control module, the output terminal of gas detecting instrument is connected with the input end of singlechip control chip, the input end of the output terminal connecting fluid cylinder pressure of singlechip control chip, also be connected with connecting rod on the hydraulic rod of oil hydraulic cylinder, the front end of this connecting rod has lower inclined plane, described oil hydraulic cylinder and connecting rod are fixed on a side of control handle, the direction of control handle when making connecting rod perpendicular to valve open.
The utility model is simple in structure, in case gas detecting instrument has monitored gas leak phenomenon, singlechip control chip will automatic operating hydraulically operated cylinder working, make connecting rod promote control handle, the closing function of realization to gas valve, thereby avoided the potential safety hazard that causes because of gas leakage, it is easy to use, highly versatile.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is scheme of installation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As extremely shown in Figure 2 in Fig. 1, a kind of based on monolithic processor controlled gas valve, comprise straight-through tube 1, valve 10 is arranged in straight-through tube 1, have swivel bolt 2 on valve 10, be fixed with valve handle 3 by the first nut 4 on this swivel bolt 2, also pass through fixedly control handle 5 of the second nut 6, the end 5-2 of this control handle 5 has the hole 5-3 that adapts with swivel bolt 2, and upper end 5-1 extends along valve handle 3 directions; Described gas valve also comprises a control module 8, have gas detecting instrument 8-1 and singlechip control chip 8-2 on this control module 8, the output terminal of gas detecting instrument 8-1 is connected with the input end of singlechip control chip 8-2, the input end of the output terminal connecting fluid cylinder pressure 7 of singlechip control chip 8-2, also be connected with connecting rod 9 on the hydraulic rod of oil hydraulic cylinder 7, the front end of this connecting rod 9 has lower inclined plane.The direction of control handle 5 when connecting rod 9 is opened perpendicular to valve 10.
The utility model is simple in structure, in case gas detecting instrument has monitored gas leak phenomenon, be about to signal and pass to singlechip control chip, the automatic operating hydraulically operated cylinder working of singlechip control chip promotes the connecting rod advance the puck, makes connecting rod arrive and promotes control handle, until realize closing of valve, thereby avoided the potential safety hazard that causes because of gas leakage, it is easy to use, highly versatile.
