Description
Technical Field
The utility model relates to a technical field that the valve industry was made, in particular to throttling assembly orifice plate structure.
Background
The valve usually keeps apart water inlet and delivery port through the case and realizes its effect of switch rivers, in order to guarantee the pressure differential of water inlet and delivery port, guarantees that core actuating mechanism's thrust is stable, improves the regulation precision, prevents that the water level is undulant great, adopts the orifice plate structure to carry out pressure control usually, and the orifice plate is drawn together to the orifice plate, but current orifice plate structure is unreasonable, and its regulation precision is lower to make hydraulic pressure's pressure differential regulation unstable.
Disclosure of Invention
To the technical problem, the utility model provides a throttling assembly orifice plate structure, its simple structure has improved the hydraulic regulation precision of valve, has guaranteed the stability of water pressure regulation.
The technical scheme is as follows: an orifice plate structure of a throttling component is characterized in that: it includes the orifice plate body, be provided with the centre bore in the orifice plate body, the orifice plate body is counter bore and orifice plate counter bore down including crisscross orifice plate, counter bore on the orifice plate with counter bore under the orifice plate with communicate through horizontal groove between the centre bore, counter bore on the orifice plate with be provided with the through-hole under the orifice plate on the counter bore.
It is further characterized in that the transverse groove width is 0.8mm-8.2 mm; a plurality of through holes are formed in the upper counter bore of the pore plate and the lower counter bore of the pore plate; the two ends of the pore plate body are in oblique angles.
The above structure is adopted in the utility model, the orifice plate body is counter bore and orifice plate counter bore under counter bore and the orifice plate on the orifice plate including crisscross orifice plate, counter bore and orifice plate under counter bore on the orifice plate with through transverse groove intercommunication between the orifice plate centre bore, be provided with the through-hole under counter bore and the orifice plate on the orifice plate, a plurality of orifice plates stack, when the valve case is opened, during counter bore inflow counter bore under the orifice plate of upper end, on the orifice plate counter bore and the transverse groove on rivers transverse groove in proper order, counter bore and the orifice plate under the orifice plate, the fluid has been realized flowing in proper order in the valve, its simple structure has improved the hydraulic regulation.
Drawings
FIG. 1 is a schematic view of the orifice plate structure of the throttling assembly of the present invention;
FIG. 2 is that of FIG. 1In the A-A directionSection view；
Fig. 3 is an enlarged view of the direction B of fig. 1.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, a throttling component orifice plate structure comprises an orifice plate body 1, a central hole 2 is arranged in the orifice plate body 1, the orifice plate body 1 comprises staggered orifice plate upper counter bores 3 and orifice plate lower counter bores 4, the orifice plate upper counter bores 3 and the orifice plate lower counter bores 4 are communicated with the central hole 2 through transverse grooves 5, the transverse grooves are 0.8mm-8.2mm in width, a plurality of through holes 6 are arranged on the orifice plate upper counter bores 3 and the orifice plate lower counter bores 4, the plurality of orifice plates are stacked, when a valve core of a valve is opened, water flows into the upper end orifice plate lower counter bores, the orifice plate upper counter bores and the orifice plate upper counter bores, and the orifice plate upper counter bores and the transverse grooves.
As shown in figure 3, two ends of the pore plate body 1 are in an oblique angle shape, when the pore plates are overlapped, a triangular groove 7 is formed between the pore plates, and the pressure of high-pressure water on the pore plates is reduced.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
