Stopper rod has tight fit relation with inner cavity；The sealing ring installation on the piston rod, with inner cavity there is elasticity to be interference fitted；It is described
Inlet pressure sensor is installed on import side wall；The outlet pressure sensor is installed on exit side wall.
The pitch and deflector hole of external screw thread and the whole circle multiple of internal thread described in the technical solution of the utility model
Spacing it is equal.
Handle described in the technical solution of the utility model by controlling or being automatically controlled by electromechanical component manually.
Shell described in the technical solution of the utility model and the piston in addition to sealing ring are made of rigid material；
The sealing ring is made of elastic material.
The utility model due to using the electronic flowmeter that is made of piston and shell, wherein, piston is column, from upper
Under be followed successively by handle, external screw thread, piston rod, sealing ring and spaced deflector hole, shell includes the column coordinated with piston
Housing and the runner housing vertical with the cylindrical shell, cylindrical shell are equipped with the inner cavity coordinated with piston and internal thread, runner shell
The both ends of body are respectively inlet and outlet, and inlet pressure sensor is respectively equipped with the runner housing of inlet and outlet and outlet is pressed
Force snesor, thus, work as rotating handles, by screw thread rotation piston rod can be driven to move up and down along inner cavity, drive is led
Discharge orifice rises or falls, and so as to complete the switching of deflector hole, the extension of measuring range is realized in an equipment.
The utility model have the characteristics that it is simple in structure, can conveniently switching different pore size deflector hole and measurement accuracy it is high.
The utility model is mainly used for the electronic flowmeter of changeable fluid.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2.A kind of electronic flowmeter of the utility model includes piston 1 and shell 2.Piston 1 is column,
Handle 101, external screw thread 102, piston rod 103, sealing ring 104, spaced first deflector hole, 105 and are followed successively by from top to bottom
Second deflector hole 106.Shell 2 includes the cylindrical shell coordinated with piston 1 and the runner housing vertical with the cylindrical shell.Column
Housing is equipped with step inner cavity 202, and the larger inner cavity in top is equipped with internal thread 201.Cylindrical shell lower lumen has with piston rod 103
There is tight fit relation.The both ends of runner housing are respectively the runner housing of import 203 and outlet 204, import 203 and outlet 204
Inlet pressure sensor 205 and outlet pressure sensor 206 are respectively equipped with side wall.Handle 101 is disc handle.External screw thread
102 have thread fitting relation with internal thread 201, and rotating handles can drive piston rod 103 to do fortune up and down along inner cavity 202
It is dynamic, drive the first deflector hole 105 and the second deflector hole 106 to rise or fall.Sealing ring 104 is installed on the sealing of piston rod 103
On groove, with inner cavity 202 there is elasticity to be interference fitted.First deflector hole 105 and the second deflector hole 106 are passing through on piston rod 103
Perforation, holes is separated by a distance, and aperture is different, and holes is parallel with import 203 and outlet 204.
Further, the pitch of the external screw thread 102 and internal thread 201 makes it rotate a whole circle or whole by design
The multiple of circle, can cause the rectilinear path of piston rod 103 to be equal to the spacing of the first deflector hole 105 and the second deflector hole 106.
Further, the handle 101 can also can be automatically controlled by controlling manually by electromechanical component.
Further, the shell 2 and the piston 1 in addition to sealing ring 104 are made by rigid material.The sealing ring
104 are made of elastic material.
On the architecture basics designed by the utility model, when rotating handles 101, band can be rotated by external screw thread 102
Piston bar 103 moves up and down along inner cavity 202, can drive the first deflector hole 105 and the second deflector hole 106 rise or under
Drop.Because the pitch of screw thread passes through special designing, when handle 101 rotates whole circle or whole circle multiple, piston rod 103 is just walked
The isometric air line distance of complete water conservancy diversion pitch of holes, so as to complete the mutual switching of the first deflector hole 105 and the second deflector hole 106.
Because handle rotation is the multiple of whole circle or whole circle, it is possible to ensures that deflector hole is still put down with import 203 and 204 directions of outlet
OK.
The utility model is simple in structure, on the premise of sealing performance is ensured, very easily completes different pore size water conservancy diversion
The switching in hole.So as to extend the range of instrument, it can quickly switch different ranges in a short time, ensure that at the same time
The accuracy of measurement.
Obvious the utility model is not limited to above example, can also there is many deformations.Those skilled in the art can be from this
All deformations that utility model content is directly exported or associated, are considered as the scope of protection of the utility model.
