Abstract
The utility model relates to a flow rate measuring valve, particularly a high-grade valve type orifice plate flow regulator with a single handle, which comprises an upper valve body, a lower valve body and an orifice plate. The utility model is characterized in that the orifice plate is fixed on an orifice plate component through a sealing element; the upper part of the orifice plate component is hinged with a slide block through a hinged bolt, and the slide block drives the orifice plate to shift from the lower valve body to the upper valve body through a screw rod and a guide post; the lower part of the orifice plate component is hinged with a turning plate playing a sealing role. The utility model has the advantages of simple and compact structure, reliable sealing, light weight, simple operation in changing the orifice diameter, etc.
Description
The utility model relates to a kind of flow measurement valve, particularly a kind of monolever advanced valve type throttle orifice plate apparatus.
General both at home and abroad at present valve-type orifice-plate throttling arrangement at work, separate valve body and sealing up and down by slide valve assembly, when under needs are continuing to flow situation, changing restricting orifice, need open equilibrium valve earlier, after making the interior equipressure of lower valve body cavity, open guiding valve, lean on a sets of transmission mechanism, the hole is led mention, close guiding valve and equilibrium valve then, pack atmospheric valve and make after the lower valve chamber release, dismantle top board and loam cake, change orifice plate.This complex structure, casting and difficulty of processing are big, Heavy Weight, the operational sequence complexity when changing orifice plate.Though some novel orifice valves are also arranged at present, " the interchangeable orifice valve of rotary type " (patent No. 94247264.0) by name as Patent Office of the People's Republic of China's bulletin in 21 days June nineteen ninety-five, it is to adopt one to be installed in rotatable porous orifice plate in the valve body and to realize changing aperture on the orifice plate, this device is when pressure is very big, seal very unreliably, cause the leakage of valve body inner fluid.
The purpose of this utility model provides a kind of monolever advanced valve type throttle orifice plate apparatus of conveniently replaced orifice plate
The technical solution of the utility model is: a kind of monolever advanced valve type throttle orifice plate apparatus, comprise upper valve body, following valve body, orifice plate, and it is characterized in that upper valve body 5 and following valve body 16 link into an integrated entity by connecting plate 12; Orifice plate 14 is fixed on the orifice plate assembly 15 by Sealing 13, and orifice plate assembly 15 upper ends are hinged by hinge bolt 10 and slide block 7, and the lower end is hinged with a turnover panel that seals 17; Slide block 7 drives it by coupled leading screw 8 and moves up and down by being fixed on guide pillar 6 location on the upper valve body 5, and leading screw 8 tops are fixed on the upper cover plate 4, are fixed with a rocking handle 3 in the end of leading screw 8.Slide block 7, guide pillar 6, leading screw 8 all are in the valve pocket of upper valve body 5 of sealing, have a hole 2 that is used to change orifice plate 14 on the upper valve body valve pocket, hole 2 by cover plate 1 with its sealing.Plate shape orifice plate assembly 15 is installed in the valve pocket of upper and lower valve body 5,16.
The utlity model has simple and compact for structure, sealing is reliable, in light weight, characteristics such as easy and simple to handle when changing orifice plate.
Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model is by upper valve body 5, following valve body 16 is formed, plate shape orifice plate assembly 15 is installed in, following valve body 5, in 16 the valve pocket, on orifice plate assembly 15, by Sealing 13 that orifice plate 14 is fixed thereon, the lower end of orifice plate assembly 15 turnover panel 17 that has been connected through the hinge, top at orifice plate assembly 15 is hinged by hinge bolt 10 and slide block 7, slide block 7 is by being fixed on guide pillar 6 location in the upper valve body 4, driving it by coupled leading screw 8 moves up and down, the upper end of leading screw 8 is fixed on the upper cover plate 4, be fixed with a rocking handle 3 in the end of leading screw 8, when rotation crank 3, leading screw 8 rotation, by with slide block 7 that leading screw 8 matches on nut drive slide block and move up and down.When slide block 7 moves up, by hinge nut 10 orifice plate assembly 15 is upwards mentioned, compress with Sealing 11 after making turnover panel 17 and forwarding horizontal position to, upper and lower valve position sealing is separated, at this moment open cover plate 1, with orifice plate 14, by taking out in the hole 2, replace with corresponding orifice plate 14, reverse operating makes orifice plate 14 arrive the relevant position then, at this moment the pressing plate 9 between slide block 7 and the orifice plate assembly 15 will seal between the upper and lower valve, turnover panel 17 under situation about not stressing, is in physical slot owing to adopted the structure of uneven weight simultaneously; Upper and lower valve body the 5, the 16th fuses it by connecting plate 12, and the slide block 7 in the upper valve body 5, guide pillar 6, leading screw 8 etc. all are in the upper valve body valve pocket of sealing.
