Problems solved by technology

In nozzle technology, in order to achieve a good spray effect, technicians actively improve the structure of each part of the nozzle and the cooperation between the parts. However, there are not many people who study the structure of the nozzle orifice plate. Generally, the nozzle orifice plate is set in On the oil pipe body or valve seat, the structure is generally to set a single hole or multiple holes on the main body of the orifice plate to achieve the effect of spraying. However, in practice, technicians have found that there is still room for improvement in this structure

Embodiment 1

[0029] Such as Figure 1-4 As shown, the present embodiment discloses a swirling orifice plate 13, which includes a main body of the orifice plate. plate) can be matched, in this embodiment, preferably a cylinder is set; at least one drainage groove 131 is arranged on one end surface of the main body of the nozzle orifice plate, and at the same time, each drainage groove 131 is provided with The oil injection hole 132, the number of the drainage groove 131 is not specifically limited, and a plurality of drainage grooves 131 are evenly distributed radially with a point on the main body of the nozzle orifice plate as a dot, preferably, the dot is a cylinder The center of the circle of the end face; further, a plurality of drainage grooves 131 are evenly arranged along a circumferential direction, preferably, the number of said drainage grooves 3 is 3; An arc segment 1311, a straight groove segment 1312, a curved groove segment 1313 and a second arc segment 1314, and preferably,...

Embodiment 2

[0032] Such as Figure 5-9 As shown, this embodiment discloses a nozzle, which includes a housing, a valve body 2, an electromagnetic assembly, a valve core, a ball 10, a valve seat 12, an orifice plate 13, etc., and the valve seat 12 includes a valve seat body. The first cylindrical cavity 121, the first frustum cavity 122, the second cylindrical cavity 123, the second frustum cavity 124, the oil outlet hole 125 and the nozzle hole plate accommodation groove 127 are successively formed in the valve seat body. Confluence grooves 126 are formed on the walls of the first frustum cavity 122 and the second cylindrical cavity 123 , preferably, the flow grooves 126 are five evenly distributed partial cylinder structures. The orifice plate 13 is placed in the accommodating groove 127 of the orifice plate and connected, and the ball is in conflict with the second frustum cavity 124 for sliding fit. Such as Figure 5 As shown, the valve seat 12 is connected to the valve body 2. At th...

Abstract

The invention discloses a rotational flow type spray hole plate. Multiple flow guide grooves are formed in the spray hole plate, and an oil spray hole is formed in each flow guide groove. After fluidmedia such as oil enter the flow guide grooves, the groove structures of the flow guide grooves can fully guide the media such as the oil to pass through the oil spray holes in the flow guide grooves,the multiple oil spray holes can quickly spray out the media such as the oil, the media such as the oil cannot stay in the flow guide grooves, and therefore the carbon deposition is reduced. Furthermore, each flow guide groove comprises a first arc-shaped section, a straight groove section, a bent groove section and a second arc-shaped section, and the first arc-shaped section, the straight groove section, the bent groove section and the second arc-shaped section of each flow guide groove are connected in sequence; due to the arrangement of the bent groove sections, the structures of the whole flow guide grooves are similar to the comma structure, and the moving tracks of the fluid media in the structures are spiral tracks; and especially, by means of the design of the multiple flow guidegrooves, when the fluid media enter the flow guide grooves, the fluid media are accelerated to enter the oil spray holes at the high speed in the mode of using the spiral tracks as the starting pointin the flow guide grooves, and therefore the fluid media flow around the flow guide grooves, the boundary sudden change is formed in the oil spray holes, and the atomization effect is improved.

Description

technical field [0001] The invention relates to the technical field of engine nozzles, in particular to a swirl-type orifice plate and a nozzle. Background technique [0002] The fuel injector is one of the key components of the EFI engine, and its work will seriously affect the performance of the engine. Existing fuel injection nozzles generally have a simple solenoid valve structure. For example, CN2016209634863 discloses a nozzle, which includes a housing, a valve body is arranged in the housing, and a coil assembly is arranged between the valve body and the housing. The valve body is provided with an adjustment sleeve and a valve core, and the valve core can slide in the valve body. A spring fixing seat is provided in the adjustment sleeve, and an elastic member is arranged between the spring fixing seat and the valve core. The front end of the spool passes through a sphere between the partition and the nozzle, the valve core is provided with several spray holes in the ...
