Abstract
The utility model discloses a kind of gas meter joint, comprise matrix, joint, the material that whole gas meter joint adopts is copper, matrix and joint are an entirety, joint is cut one section of screw thread, screw thread with need the internal thread of the accumulator unit measuring air pressure to screw, matrix is cut one with the rectangular channel of its axes normal, the cylinder of this groove and gas meter is tightly connected, a circular hole is drilled with from the center of joint, circular hole extends to rectangular channel and communicates with it, the gas of accumulator unit transfers to gas meter cylinder from circular hole through rectangular channel, when the gaseous tension in gas meter cylinder changes, the pointer of gas meter deflects, read gaseous tension in accumulator unit, structure of the present utility model is very simple, save material, assemble very convenient, because the material adopted is copper, therefore more corrosion-resistant.
Description
Technical field
The utility model relates to gas pressure detection technical field, particularly relates to a kind of gas meter joint.
Background technology
Along with the application of combustion gas in all trades and professions is increasingly extensive, demand for the gas meter class device detecting air pressure is increasing, because combustion gas is the gas that a kind of corrosivity is larger, the part be in contact with it is very easy to be corroded, therefore the material of part being used for producing gas meter must have good corrosion resistance, the material of the longer employing of current people is copper, and copper is as the higher material of a kind of price, should practice every conceivable frugality during use, then just seem necessary with the design of the planform of the correlated parts of gas meter.
Utility model content
The purpose of this utility model is exactly perishable in order to overcome above-mentioned prior art gas meter class device, waste material, the defect that price is high, devise that a kind of structure is very simple saves material for barometric joint, easy to assembly, adopt copper as starting material, therefore more corrosion-resistant.
The required technical matters solved of the utility model can be achieved through the following technical solutions:
A kind of gas meter joint, comprise matrix, joint, the material that whole gas meter joint adopts is copper, described matrix and described joint as a whole, a groove has been cut in the bottom of described matrix, the front and rear wall of this groove has bored two threaded holes respectively, and these threaded holes adopt screw to be connected with the gentle watch case of gas meter index dial respectively.
Described matrix is an xsect is foursquare rectangular parallelepiped.
Cut on the matrix one with the rectangular channel of its axes normal, the cylinder of this groove and gas meter is tightly connected.
Described joint is a right cylinder, and chamfering has been carried out in cylindrical end, and it has been cut one section of screw thread, screw thread with need the internal thread of the accumulator unit measuring air pressure to screw.
The center of described joint is drilled with a circular hole, and circular hole extends to rectangular channel and communicates with it.
Owing to have employed above technical scheme, the utility model tool has the following advantages:
Adopt the design that matrix and joint etc. combine, provide a kind of gas meter joint, adopt copper as starting material, therefore this gas meter joint is more corrosion-resistant, from designed joint design, be a simple rectangular parallelepiped and right cylinder combination, very simply, save material, no matter and this structure be with gas meter or be connected with accumulator unit all very convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of gas meter joint, comprise matrix 1, joint 2, the material that whole gas meter joint adopts is copper, matrix 1 is as a whole with joint 2, and a groove has been cut in the bottom of matrix 1, and the front and rear wall of this groove has bored two threaded holes 6 and 7 respectively, threaded hole 6 is connected with gas meter index dial screw, and threaded hole 7 and gas meter shell are also adopt screw to be connected, and the existence of groove reduces the weight of gas meter joint.
Matrix 1 is an xsect is foursquare rectangular parallelepiped.
Matrix 1 is cut one with the rectangular channel 5 of its axes normal, groove 5 is tightly connected with the cylinder of gas meter.
Joint 2 is a right cylinder, and chamfering has been carried out in cylindrical end, and it has been cut one section of screw thread 3, screw thread 3 with need the internal thread of the accumulator unit measuring air pressure to screw.
A circular hole 4 is drilled with from the center of joint 2, circular hole 4 extends to rectangular channel 5 and communicates with it, the gas of accumulator unit transfers to gas meter cylinder from circular hole 4 through rectangular channel 5, when the gaseous tension in gas meter cylinder changes, the pointer of gas meter deflects, read gaseous tension in accumulator unit, realize the object detecting air pressure.
Gas meter joint designed by the utility model, owing to adopting copper as starting material, therefore this gas meter joint is more corrosion-resistant, from designed joint design, be a simple rectangular parallelepiped and right cylinder combination, very simple, save material, no matter and this structure be with gas meter or be connected with accumulator unit all very convenient.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
