Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further explained to explanation:
With reference to Fig. 1, the structure of the removable restricting orifice of the utility model mechanism is specially: the quantity that on distributor 4, distributor liquid outlet 7 relative directions are provided with installing hole 8(distributor liquid outlet 7 and corresponding installing hole 8 is determined according to the quantity of design restricting orifice assembly), described distributor 4 direction relative with installing hole 8 is provided with pipe joint 1, described pipe joint 1 internal thread is connected with described restricting orifice assembly 3, the top end face of described restricting orifice assembly 3 has throttle orifice 3.1, described throttle orifice 3.1 is communicated with the endoporus 3.2 of restricting orifice assembly 3, on described distributor 4, installing hole 8 places are provided with tubular flange 5, plug 6 inserts in installing hole 8 through tubular flange 5.The back segment cross section of described endoporus 3.2 is polygon (as pentagon, hexagon).Endoporus 1.1 back segment 1.12 internal diameters of described pipe joint 1 are greater than leading portion 1.11 internal diameters; The external diameter of described restricting orifice assembly 3 back segments 3.4 is greater than the external diameter of leading portion 3.3, back segment-3.4 outer wall is provided with the external screw thread with the screw-internal thread fit of pipe joint 1, leading portion is set with spring 2, and the end face of described spring 2 compresses and contacts with the end face of pipe joint 1 endoporus 1.1 back segments 1.12.
With reference to Fig. 2, in restricting orifice mechanism, the dismounting of restricting orifice assembly is specially by the structure of instrument: comprise barred body 9, the polygon boss 10(mating with endoporus 3.2 hypomeres of restricting orifice assembly 3 is equipped with as pentagon, hexagon in the top of described barred body 9).Described polygon boss 10 is provided with the throttle orifice limit stick 11 that diameter is less than throttle orifice 3.1 apertures, and the bottom of described barred body 9 is provided with handle 12.
With reference to Fig. 3, disassembly process:
In the time need to restricting orifice assembly 3 being installed to the distributor liquid outlet 7 of distributor 4, by the interior taking-up plug 6 of installing hole 8, then the endoporus of restricting orifice assembly 3 3.2 back segment 3.4 correspondences are sleeved on the polygon boss 10 on barred body 9 tops of described dismantling device, the corresponding throttle orifice 3.1 that passes in top of throttle orifice limit stick 11 is realized the centering of restricting orifice assembly 3 spacing, can prevent that restricting orifice assembly 3 from falling into distributor 4 in installation and removal process, is so just contained in restricting orifice assembly 3 on dismantling device in advance, the handle 12 of the hand-held barred body of operator 9 bottoms, by installing hole 8, restricting orifice assembly 3 is sent into distributor liquid outlet 7 places, then a sideway swivel handle 12, make handle 12 drive the corresponding rotation of restricting orifice assembly 3, making the inwall of throttle orifice board component 3 back segment 3.4 outer walls and pipe joint 1 realize screw thread tightens, when screw thread is tightened, also make the spring 2 being sleeved on outside restricting orifice assembly 3 leading portions 3.3 be compressed by the end face of the back segment 1.12 of pipe joint 1.1, under two active forces that screw thread is tightened and spring 2 compresses, restricting orifice assembly 3 is firmly arranged in pipe joint 1, and realize and being communicated with pipe joint 1 by throttle orifice 3.1, last operation person pulls down fixed handle 12, polygon boss 10 is exited by endoporus 3.2 back segments of restricting orifice assembly 3, corresponding throttle orifice limit stick 11 is also by exiting in throttle orifice 3.1, until whole dismantling device is gone out to exit by installing hole 8, again in installing hole 8, load onto plug 6 again, distributor 4 is the airtight installation process that realizes restricting orifice assembly 3 again.
When stopping up appears in the restricting orifice assembly 3 in distributor 4, need to change restricting orifice assembly 3, or need to carry out the operations such as reaming to the throttle orifice of restricting orifice assembly 3 3.1 time: first take off plug 6, the handle 12 of the hand-held dismantling device of operator, the polygon boss 10 of dismantling device is sent into distributor liquid outlet 7 places, and the top that makes throttle orifice limit stick 11 is corresponding to throttle orifice 3.1, the corresponding plug-in mounting of endoporus 3.2 back segment of polygon boss 10 and restricting orifice assembly 3; Then counter-rotate handle 12, drive also respective opposed rotation of restricting orifice assembly 3, make throttle orifice board component 3 back segment 3.4 outer walls remove with pipe joint 1 inwall the state being threaded, spring 2 is also no longer pressed on the end face of back segment 1.12 of pipe joint 1.1, under the effect of spring 2, restricting orifice assembly 3 is sleeved on according to gravity on the polygon boss 10 of dismantling device, now operator pulls down fixed handle 12, by all exiting in installing hole 8, realize the unloading process of restricting orifice assembly 3 with the dismantling device of restricting orifice assembly 3;
When needs when restricting orifice assembly 3 is newly installed, method of operating is the same.By using special dismantling device, make the disassembly process of restricting orifice assembly 3 very simple, do not destroy distributor or associated conduit, quick and convenient.Stop up cleaning as example taking certain device gasification furnace water-steam system pipe throttle orifice plate described in background technology, if adopting the utility model structure transforms distributor, coordinate special dismantling device, whole dismounting and cleaning process only needs a few minutes, do not affect the driving operation of device completely, the effective guarantee yet obtaining the service life of equipment.
