Description
Technical Field
The utility model belongs to the technical field of water gauge flow test equipment technique and specifically relates to indicate an external adjustment formula dry-type core impeller box.
Background
The traditional dry-type water meter core impeller box (meter) is an internal regulation type, the mode of an impeller box bottom regulation hole and a side wall regulation hole is adopted, the regulation is carried out in advance, the impeller box (meter) is installed in a meter shell during installation, then the impeller box (meter) and each sealing piece are assembled in a rotating mode and then subjected to flow verification, when the flow verification is unqualified, all disassembly is needed, the impeller box is assembled again in a readjusting mode, and finally the flow verification is carried out again.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide an external mode dry-type core impeller box can carry out the external adjustment again after impeller box, casing and each sealing member have all been assembled during the equipment, avoids the basic table to assemble the back because the unqualified dismouting adjustment that needs again of flow, has promoted production efficiency. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides an external mode dry-type core impeller box, includes impeller box body, be equipped with upper cover plate and lower apron on the impeller box body, apron bottom annular distribution is equipped with three breakwater down, and is three at least one is adjustable breakwater among the breakwater, adjustable breakwater central connection has the governing valve, be equipped with the mounting hole on the upper cover plate, the governing valve runs through the apron down and fix through sealing washer and adjusting nut in the mounting hole.
Further, the adjusting valve and the adjustable water baffle are integrally formed.
Further, the sealing ring is arranged inside the upper cover plate.
(III) advantageous effects
Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, the utility model discloses with original three breakwater design for having at least one for the adjustable breakwater, through the manger plate area of rotatory adjustable breakwater for the water goes out the water runner and takes place to change, reaches flow control, can all assemble the back at impeller box, casing and each sealing member when the structural design of external mode assembles, carries out the external regulation again, avoids the basic table to assemble the back because the unqualified dismouting adjustment that needs again of flow, has promoted production efficiency.
