Four channel openings with phase difference of 90 DEG are arranged on the control plate of the gas channel around the through hole, and the four channel openings are totally covered by the cock valve and are corresponding to the gas inlet and the gas collecting cavity; simultaneously, four independent sealing flow guide grooves are also arranged between the control plate of the gas channel and a casing; one end of each flow guide groove is communicated with a corresponding measuring room, and the other end is communicated with the corresponding channel openings on the control plate of the gas channel. The four flow guide grooves not only can enable the gas to orderly enter the corresponding measuring rooms, but also can enable the gas of the measuring rooms to flow out of the corresponding flow guide grooves, so the whole structure is simple, the gas can swimmingly flow, and membrane pieces can be orderly pushed to make reciprocating movement; thus, uniform rotation of the cock valve is ensured, and accurate measurement can be realized.
Description
Technical field
The present invention relates to a kind of gas meter, flow meter, especially refer to a kind of flow-guiding structure of core of membrane type gas meter.
Background technology
Because gas meter, flow meter can be used to measure the integrated flow of inflammable gas, thereby be widely used in occasions such as family, restaurant, and the respiratory movement that its measuring principle normally utilizes diaphragm is by flagpole and the connecting rod that is hinged with it, give the ventilation stopcock with transmission of power, promote the stopcock rotation and make gas meter, flow meter carry out air inlet and exhaust work, thereby realized the volumetric metering of combustion gas preferably.But in actual manufacturing and use, find,, therefore be easy to occur stopcock and rotate the phenomenon of being obstructed and produce dead table because the inside air flue of existing this gas meter movement flow-guiding structure is comparatively complicated, and adds limited pipe gas flowing pressure.Moreover the contact area between stopcock and the air flue control panel is bigger, increasing between the two in the frictional resistance, also makes the stopcock wearing and tearing easily and shortens its serviceable life.Thereby such gas meter movement flow-guiding structure awaits further perfect.
Summary of the invention
Technical matters to be solved by this invention is the present situation at prior art, and a kind of flow guide structure of core of membrane type gas meter of simple in structure, accurate measurement is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this flow guide structure of core of membrane type gas meter, it comprises and is positioned at that housing is symmetrical arranged and two diaphragms that housing both sides inner chamber are separated into four measuring rooms, be positioned at the air flue control panel and the stopcock that is arranged on the air flue control panel of diaphragm top, wherein, be respectively equipped with gas inlet and gas outlet on described stopcock and the air flue control panel, it is characterized in that: described stopcock inside surface is provided with the air collecting chamber that becomes 180 ° of phase differential with above-mentioned air intake opening, and have the through hole that connects with described air collecting chamber at the middle part of described air flue control panel, on its bottom surface, be provided with the outlet passageway that is communicated with this through hole and above-mentioned gas outlet, and design has phase differential to become four passwaies of 90 ° on the air flue control panel around the described through hole, and these four passwaies all cover under the described stopcock and are relative with described air intake opening and air collecting chamber, between described air flue control panel bottom surface and described housing, also design simultaneously four independent sealed diversion trenchs are arranged, one end of each diversion trench is connected with a corresponding measuring room, the other end then with described air flue control panel on the respective channel mouth connect.
As a further improvement on the present invention, can be provided with two donuts with the corresponding contact of bottom anchor ring of described stopcock on the described air flue control panel.
As another kind of improvement the of the present invention, described air flue control panel and stopcock all can adopt the plastic material that is added with graphite.
In above-mentioned each scheme, can be connected by gluing between described air flue control panel and the housing.
Compared with prior art, four diversion trenchs the invention has the advantages that: owing to both can make combustion gas enter corresponding measuring room in an orderly manner, the combustion gas of measuring room is flowed out by corresponding diversion trench, thereby total is simple relatively, and fuel gas flow is smooth and easy, and can promote diaphragm in an orderly manner and make it to produce to-and-fro movement, realize accurately metering to guarantee stopcock evenly to rotate.Have and contacted two donuts of stopcock owing to designing on the air flue control panel simultaneously, thereby realizing also helping simultaneously in relative rotation to reduce contact area.Moreover the air flue control panel adopts the identical material that has graphite with stopcock, can increase lubricity and wearing quality between the two, so that reduce wearing and tearing.In addition, air flue control panel and housing are carried out glue are stained with, make assemble up more convenient, quick.
