Embodiment
To describe the specific embodiment of the utility model below in detail.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the utility model.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the back pressure regulator device that is used for engine performance measuring of the utility model is mainly used on the engine pedestal.Engine pedestal is provided with the plurality of sections gas outlet, and the adjacent rows tracheae is connected by the butt joint of a pair of flange, during test waste pipe is communicated with gas outlet on the engine pedestal.
Back pressure regulator device comprises that the left flange 3 that is installed on the engine pedestal gas outlet 2 and can dock connection, right flange 6 and one process the high temperature resistant plate 1 that thickness is 2mm by carbon steel material, and certain high temperature resistant plate 1 also can be processed by other resistant to elevated temperatures metal materials or nonmetallic materials.High temperature resistant plate 1 can be a rule or irregular tabular, if can with engine pedestal gas outlet 2 cooperatings, promptly get final product through the gas flow area that engine pedestal gas outlet 2 can be regulated in the position that changes high temperature resistant plate 1.Preferred high temperature resistant plate 1 is shaped as circle and lacks shape, and is not only easy to adjust, and saves material, attractive in appearance again.Thickness is the high temperature resistant plate 1 of 2mm, existing enough intensity, and very convenient again sealing, but the thickness of high temperature resistant plate 1 is not limited to 2mm, and its thickness all is feasible in the 1.5-3mm scope usually.
High temperature resistant plate 1 has a breach; The area of this barbed portion is corresponding to 30% of engine pedestal gas outlet 2 circulation areas (cross-sectional area); But not as limit; The area of this barbed portion is the 20%-30% of engine pedestal gas outlet 2 cross-sectional areas, so that all be feasible under the 70%-80% situation of high temperature resistant plate 1 covering engine stand gas outlet 2 circulation areas, cross-sectional area and the engine of specifically looking the exhaust pipe of engine the car situation and confirmed.When on engine pedestal, doing emission testing, need consider the sealing problem of gas outlet; Therefore when the utility model is used to do emission testing,, prevent gas leakage for the sealing property of further reinforced platoon tracheae; Can between high temperature resistant plate 1 and said left flange 3 or right flange 6, be provided with and have certain flexible sealing gasket 9; Preferably, can use the asbestos seal pad, it comprises interior copper layer, outer copper layer and middle asbestos layer; Have high temperature resistant plate 1 place, the asbestos seal pad is extruded thinlyyer; At the gap position of high temperature resistant plate 1, because elasticity, the thickness of asbestos seal pad is thicker relatively, still can keep contacting with left and right flanges, thereby play good sealing function.Sealing gasket 9 can assume diamond in shape, and has and the identical through hole of gas outlet 2 internal diameters in central authorities, but not as limit, and other shapes also are fine like the circle of band center through hole etc.And in other test; Test like traditional performances such as general power test, universal characteristic test, engine reliability tests; Then do not require under the gas outlet air-proof condition and carry out; Then can use seal, at this moment when confirming the thickness of high temperature resistant plate 1, also need not to take into account the problem that whether seals easily.
The circumferential outer edge of high temperature resistant plate 1 is provided with a handle 11 and is connected ear handle 12 with one, and handle 11 can be a peripheral hardware with being connected ear handle 12, and preferably, handle 11, connection ear handle 12 are structure as a whole with high temperature resistant plate 1.Connect ear handle 12 and be provided with mounting hole 121, handle 11 stretches out outside the flange.In advance through the pairing position of the various different back pressures of calculating of exhaust circulation pipe area; Carry out mark in these positions with groove 111 then; Thereby draw the corresponding relation of each the bar groove 111 on various different back pressure values and the handle 11, this is very easy to test.And when not having these grooves 111,, also can satisfy the basic demand of test though test process can bother.In shown in Figure 1, barbed portion is positioned at the bottom of high temperature resistant plate 1, and handle 11 is positioned at the top of high temperature resistant plate 1, connects the right side that ear handle 12 is positioned at high temperature resistant plate 1.In actual the use, it is definite arbitrarily that tool factors such as place situation originally can be looked in the position of handle 11, connection ear handle 12 and barbed portion, as long as convenient installation and adjusting.
As shown in Figure 2, during installation, the mounting hole 121 of the connection ear handle 12 on high temperature resistant plate 1 right side and mounting hole 7 on left flange 3, the right flange 6 are aligned; Under the situation that is provided with sealing gasket 9; Can the mounting hole on the sealing gasket 9 be aligned in the lump, with the coupling bolt (not shown) pass each mounting hole of aligning again fastening nut get final product, in order to prevent movement interference; Can wear bolt in the mounting hole that only two align therein, two do not wear bolt in addition.When unclamping bolt a little, it serves as that axle rotates with the bolt 8 that connects in the ear handle 12 that turning handle 11 can drive high temperature resistant plate 1, thereby can regulate the gas flow through gas outlet, and then regulates the exhaust back pressure value.It should be noted that during installation: if do not have breach on the high temperature resistant plate 1, high temperature resistant plate 1 is all covered the xsect of gas outlet, and should reserve about cross-sectional area of about 30%, can normal starting to guarantee engine.When need regulating exhaust back pressure, unclamp bolt a little, handle 11 is turned to the position of corresponding groove 111, fastening bolt get final product again, the test needs that just can realize like a cork in the engine test process different exhaust back pressures like this.
The engine pedestal of the utility model comprises frame, is arranged on the gas outlet on the frame, and the back pressure regulator device that is used for engine performance measuring of the utility model is installed on the gas outlet.
Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.Because the utility model practical implementation and do not break away from the spirit or the essence of utility model in a variety of forms; So be to be understood that; The foregoing description is not limited to any aforesaid details; And should in enclose spirit that claim limited and scope, explain widely, therefore fall into whole variations and remodeling in claim or its equivalent scope and all should be the claim of enclosing and contain.
