Abstract
The utility model discloses a novel single-stage adjustable throttle orifice plate which is formed by a first throttle disk flange, a second throttle disk flange and a throttle disk, wherein the first throttle disk flange and the second throttle disk flange are located at two sides and fastened through fastening bolts, the throttle disk is assembled with the first throttle disk flange and the second throttle disk flange through an annular groove via stainless steel balls, the stainless steel balls can rotate, an inclined surface is formed on the throttle disk to form a gear face, a cone wheel is arranged on a corresponding position of the gear face, and the cone wheel is connected with an adjusting bolt. The adjusting bolt is installed on the first throttle disk flange through a hole in a sealed mode. Eccentric through-flow holes of the first throttle disk flange, the second throttle disk flange and the throttle disk are circular holes with the same radius. According to the novel single-stage adjustable throttle orifice plate, sizes of flow-guide holes of the throttle orifice plate can be changed when cooling water normally operates, the flow rate of the cooling water is further changed, and the problems of time-delaying and work-delaying brought by continuous replacement of different throttle orifice plates when the flow rate of a conventional throttle orifice plate needs to be regulated are avoided.
Description
Technical field
The utility model relates to a kind of single-stage adjustable orifice plate, applies to the water lines installing engineering.
Background technique
In the water power plant cooling water system was built, each unit pipeline of cooling water need use restricting orifice to control the unit of flow that respectively supplies water, and reaches optimum flow and satisfies each cooling water user cooling requirement.When adopting common restricting orifice generally speaking, for the selection of restricting orifice, in debug process, according to the test traffic result, need constantly to change the restricting orifices of different sizes, the replacing process is consuming time, consumption power, delays the debugging progress.
Summary of the invention
The purpose of this utility model is: in order to address the above problem, a kind of single-stage adjustable orifice plate is provided, be installed on the water supply constituent parts inlet pipeline, change flow by changing restricting orifice pod apertures size, working principle is simple and practical, can avoid adopting common restricting orifice constantly to change the problem that restricting orifice delays work and mistakes.
The utility model is by forming by clamping bolt fastening the first segment flow table flange that is positioned at both sides, the second throttling dish flange and throttling dish, the throttling dish assembles by circular groove and first segment flow table flange, the second throttling dish flange through stainless shot, stainless shot can be realized the rotation rotation, offer the inclined-plane at the throttling dish and form gear face, the gear face corresponding position arranges taper cone pulley, connects on the taper cone pulley to regulate bolt.
Adjusting bolt penetration hole first segment flow table flange seal described in the utility model is installed.
The eccentric through flow hole of first segment flow table flange described in the utility model and the second throttling dish flange, throttling dish is with the radius circular hole.
The utility model can change restricting orifice pod apertures size when cooling water normally moves, and then changes cooling water flow, constantly changes the problem of mistaking, delaying work that different restricting orifices brings when having avoided conventional restricting orifice to regulate flow because of need.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is by forming by the clamping bolt 6 fastening first segment flow table flange 1 that is positioned at both sides, the second throttling dish flange 2 and throttling dishes 4.4 through stainless shot 5 by circular groove and first segment flow table flange 1,2 assemblings of the second throttling dish flange, stainless shot 5 can be realized the rotation rotation, offer the inclined-plane at throttling dish 4 and form gear face 7, gear face 7 corresponding positions arrange taper cone pulley 8, connect on the taper cone pulley 8 to regulate bolt 3.Regulating 1 sealing of bolt 3 perforation first segment flow table flanges installs.The eccentric through flow hole of first segment flow table flange 1 and the second throttling dish flange 2, throttling dish 4 is with the radius circular hole.
Working principle of the present utility model is as follows: utilize eccentric circle common factor principle, with two circular hole stacks with radius, by rotate the common factor that changes two circular holes around eccentric point, reach the purpose that changes the orifice plate flow area.Utilize gear transmission will laterally rotate the principle that is converted into vertical rotation, regulate the bolt rotation is coupled to drive the throttling dish through gear end plate fluted disc rotation by taper cone pulley.
Claims (3)
