Abstract
The utility model relates to a high-pressure throttling device for light and mini-size smooth pressure-transferring tubes, which is composed of a thread flange, and a pressure tapping and throttling elements subassembly. The throttling elements of the throttling device and a pressure tapper are combined into an integral structure, and the utility model is directly connected with an exterior meter by a smooth pressure-transferring tube. So the utility model has the advantages that the utility model is convenient and light; the size is small; the manufacture, the installation, the disassembly, and the maintenance are convenient, and the steels can be saved.
Description
The utility model relates to the restriction device that the high-pressure fluid flow measurement in a kind of industrial automation specialty is used.
Existing high pressure restriction device all adopts corner connection pressure method, or flange pressure method, promptly by pressure vessel (flange) restricting element (orifice plate or circular arc nozzle) is clipped in wherein, for measurement instrument provides the pressure approach.Measurement instrument and connecting pipe couple together with parts such as screw thread flange, German-style metal lensring and stud bolts.These two kinds of used parts of restriction device are more, cost height and dismounting difficulty; Moreover these two kinds of device volumes are big, heavy, be difficult for carrying and installation, and rolled steel dosage are big.
The utility model is at the problems referred to above, design a kind of both light, the restriction device that volume is again little, it is convenient to make, installs, dismounting and maintenance, and has saved steel.
The purpose of this utility model is to realize like this, it combines restricting element and pressure vessel, forms an one-piece construction, and adopts smooth connecting pipe directly to be connected with measurement instrument, the used part of restriction device has reduced like this, and overall weight has also alleviated.
Fig. 1 is a cut-open view of the present utility model
Fig. 2 is an A partial enlarged drawing of the present utility model
Fig. 3 is the local connection diagram of A of the present utility model
The restriction device that the utility model proposes is made up of the screw thread flange 1, screw thread flange 2 and the restricting element pressure vessel subassembly 5 that are directly installed on the industrial pipeline 3,4, sees Fig. 1.Satisfying under GB GB2624-81 and the conventional restriction device structural condition, simultaneously, under the condition that guarantees compressive resistance, restricting element and pressure vessel are designed to an one-piece construction---subassembly 5, then the used part of restriction device has just reduced, and physical dimension has reduced.For guaranteeing physical strength and reaching the purpose of pressure texture size, need carry out intensive treatment to material, such as the satin roughcast, to improve its permissible stress.When carrying out flow measurement, subassembly 5 is fixed on the industrial pipeline 3,4, and then screw thread flange 1,2 is tightened up with bolt with screw thread flange 1,2.Therefore when maintenance or dismounting, only need the screw thread flange unclamped and get final product.
The utility model adopts smooth connecting pipe (seeing A portion and Fig. 2 among Fig. 1) directly to be connected with extraneous measurement instrument, and the surface that is about to connecting pipe makes smooth, with standard jig 6 smooth connecting pipe and extraneous measurement instrument is coupled together, and sees Fig. 3.This has not only reduced screw thread flange, German-style metal lensring and the stud bolt that connects usefulness, and easy accessibility, but the one man operation is time saving and energy saving, helps the fast processing of field failure.
Claims (2)
1. the high pressure restriction device of a smooth connecting pipe is made up of screw thread flange and restricting element pressure vessel subassembly, it is characterized in that the restricting element of restriction device and pressure vessel are combined as an one-piece construction.
2. restriction device according to claim 1 is characterized in that adopting smooth connecting pipe directly to be connected with extraneous measurement instrument.
