Description
Technical field
The utility model belongs to gas meter, flow meter field, the pre-assembling structure valve seat of especially a kind of gas meter, flow meter.
Background technology
At present, in domestic gas table assembling process, central shaft is by being manually vertically fixedly mounted with in mounting groove made in the middle part of following table body by central shaft by hammering the mode of striking into shape, then is inlaid in following table body by valve seat through this axle, and during prior art artificial mounting center axle, assemblage gap is larger, easily there is deviation, and, cause friction force comparatively large, affect transmission accuracy, installation procedure complex steps, installation accuracy is difficult to reach unified standard.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the pre-assembling structure valve seat of gas meter, flow meter that a kind of structure is simple, design science, cost are lower, easy to use.
The utility model solves its technical matters and takes following technical scheme to realize:
The pre-assembling structure valve seat of a kind of gas meter, flow meter, comprise valve seat, tubing through holes and center pit, valve seat body shape is match with following table body structure plate shaped, valve seat is shaped with tubing through holes, valve seat both lateral sides is all shaped with the spacing block set coordinated with made gathering sill in following table body, it is characterized in that: in the middle part of valve seat, be shaped with center pit, this center pit central coaxial is shaped with the cylindrical bore pipe mated with central shaft, this axis hole inner coaxial tube is coated with a central shaft, central shaft above axis hole pipe is coaxially shaped with a spacing back-up ring, on central shaft below this axis hole pipe, coaxial engagement is provided with a stop nut, central shaft is fixed on valve seat by this stop nut.
And radial equipartition is shaped with multiple baffle plate 5 outside described axis hole pipe and between center bore inner wall, is coaxially shaped with an annular retaining ring between center pit and axis hole pipe.
And described valve seat upper end outside spacers is shaped with multiple limited post.
Advantage of the present utility model and good effect are:
The utility model relies on gear drive, and transmission accuracy is high, and reading accuracy is high, and the assemblage gap of this structure is little, delicate structure, easy for installation, and promote assembly efficiency, promote working (machining) efficiency, gear shaft and counter housing are integrally made, and reduce costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The pre-assembling structure valve seat of a kind of gas meter, flow meter, comprises valve seat 1, tubing through holes 6 and center pit, and valve seat body shape is match with following table body structure plate shaped, and valve seat is shaped with tubing through holes; In order to erection & lift stability, valve seat both lateral sides is all shaped with the spacing block set 7 coordinated with made gathering sill in following table body.
For the ease of installing location, valve seat upper end outside spacers is shaped with multiple limited post 4.
Innovative point of the present utility model is:
Center pit is shaped with in the middle part of valve seat, this center pit central coaxial is shaped with the cylindrical bore pipe 8 mated with central shaft, this axis hole inner coaxial tube is coated with a central shaft 3, central shaft above axis hole pipe is coaxially shaped with a spacing back-up ring 2, on central shaft below this axis hole pipe, coaxial engagement is provided with a stop nut 9, and central shaft is fixed on valve seat by this stop nut.
Radial equipartition is shaped with multiple baffle plate 5 outside axis hole pipe and between center bore inner wall, is coaxially shaped with an annular retaining ring between center pit and axis hole pipe, and the through hole space between baffle plate and annular retaining ring is large, ventilates smooth.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
