Abstract
The utility model relates to a porous pressure-tapping tower-shaped flow meter which can clear blocks on line, and comprises a measuring pipe, and a positive and a negative pressure-tapping ring cavity bodies are arranged out of the measuring pipe, a positive pressure-tapping hole and a negative pressure-tapping pipe which are communicated with the positive and the negative pressure-tapping ring cavity bodies are arranged on the measuring pipe, and block clearing devices which are corresponding to the positive pressure-tapping pipe and the negative pressure-tapping pipe are arranged on the positive and the negative pressure-tapping ring cavity bodies. The porous pressure-tapping tower-shaped flow meter can clear dirties blocked in the positive and the negative pressure-tapping holes (pipes) through screwing a screw cap under a permitted technique condition, the screw cap is tightly screwed after finishing, and the flow meter can normally work. Since the above technical proposal is adopted, blocks can be cleared on line under the circumstance that once a plurality of holes are blocked, and permanent and normal work of the flow meter can be assured. The utility model has the advantages of simple structure, convenient operation and the like.
Description
Technical field
The utility model relates to a kind of instrument and meter of measuring the pipeline fluid flow, specifically a kind of turriform flowmeter of porous pressure that can online block clearing.
Background technology
Turriform (V-arrangement awl) flowmeter of porous pressure at present, greatly improved the susceptible to plugging disadvantage of single hole pressure, but extremely abominable because of process conditions sometimes, do not get rid of the also generation of the blocked situation of possibility of porous takes place, will cause the flowmeter cisco unity malfunction like this.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, can online removing tamper, can guarantee the permanent operate as normal of flowmeter can online block clearing the turriform flowmeter of porous pressure.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of turriform flowmeter of porous pressure that can online block clearing, comprise measuring tube, the measuring tube outside is provided with positive and negative pressure ring cavity body, measuring tube is provided with positive pressure port and the negative pressure pipe that communicates with positive and negative pressure ring cavity body, is provided with on positive and negative pressure ring cavity body and positive pressure port and the corresponding block clearing device of negative pressure pipe.
Described block clearing device comprises block clearing joint and nut, and the block clearing joint is provided with the screw thread that matches with nut.
Be provided with gasket seal between described block clearing joint and the nut.
Seal by taper-thread between described block clearing joint and the nut.
The utility model is by on turriform (V-arrangement awl) the flowmeter basis of porous pressure, on the positive and negative pressure ring cavity body of measuring tube; Several positive pressure ports in the corresponding measuring tube, negative pressure pipe position are provided with several block clearing joints, and this has a dismountable sealing nut above joint.Under the condition that technology allows, the nut of outwarding winding can be removed the foul that stops up in the positive and negative pressure port (pipe), screws the nut flowmeter after finishing again and gets final product operate as normal.
Owing to adopt technique scheme, in case solved under the also blocked situation of porous, can online removing tamper, can guarantee the permanent operate as normal of flowmeter, and have advantages such as simple in structure, easy to operate.
Description of drawings
Fig. 1 is the utility model high-pressure side side structure synoptic diagram;
Fig. 2 is the utility model low pressure end side structure synoptic diagram;
1. measuring tubes wherein, the pressure ring cavity of 2. officiallying enroll, 3. negative pressure ring cavity body, 4. positive pressure port, 5. negative pressure pipe, 6. block clearing joint, 7. nut, 8. gasket seal.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, Fig. 2, on the positive and negative pressure ring cavity body 2,3 of measuring tube 1; Several positive pressure ports 4 in the corresponding measuring tube 1, negative pressure pipe 5 positions, correspondence is welded with several threaded block clearing joints 6, this has a dismountable sealing nut 7 above joint, 7 available gasket seals 8 of block clearing joint 6 and nut or taper-thread sealing.Under the condition that technology allows, the nut 7 of outwarding winding can be removed the foul that stops up in positive pressure port 4, the negative pressure pipe 5, screws nut 7 after finishing again, and flowmeter gets final product operate as normal.
