The combined pitot tube comprises a backrest-type velocity measuring tube and an extraction tube connected with the backrest-type velocity measuring tube, the backrest-type velocity measuring tube is clamped in a head connecting piece, the two ends of the backrest-type velocity measuring tube extend out of the head connecting piece, two ports of the head connecting piece are respectively provided with external threads, one end of the head connecting piece is connected with a protective cover in a screwed manner, the head portion of the backrest-type velocity measuring tube is covered by the protective cover, the other end of the head connecting piece is connected with an extension tube in a screwed manner, the tail portion of the backrest-type velocity measuring tube is covered by the extension tube, an end cover is connected with the other end of the extension tube in a screwed manner, the extraction tube is clamped in the end cover, and the extraction tube and the backrest-type velocity measuring tube are connected through silicone tubes. The combined pitot tube can be combined into tubes with different lengths, the universality is good, the thickness of connecting portion is identical to the thickness of other portions after combination, and the carrying and the usage are facilitated. The combined pitot tube has the function of direction locating indication, and the accurate holding direction in a using process can be ensured. The backrest-type velocity measuring tube is used as a one-time measuring element, the connection of the velocity measuring tube is achieved through the silicone tubes, and the velocity can be tested in an airflow with the temperature of below 200 DEG C.
Description
Technical field
The utility model relates to a kind of parts that test the speed, and relates in particular to a kind of combined type pitot tube.
Background technology
Measuring wind speed is a job of the most often carrying out in power plant boiler test, and utilizing pitot tube test is one of conventional method of measuring wind speed.According to relevant rules, adopt gridding method to measure, need to test a plurality of points in tested air channel, the larger required pitot tube in air channel is just longer, is to meet usually 4 meters of above pitot tubes of needs of testing requirement in real work.The long inconvenience of carrying that pitot tube is made, need to be used oversize vehicle to increase transportation cost for carrying pitot tube.Also have and pitot tube is made knockdown, but syndeton is unreasonable, and other are local thick than pitot tube for connecting portion, inconvenient while converting test position during use.
Summary of the invention
The purpose of this utility model is to provide a kind of and puts easy to carryly, plugs combined type pitot tube smoothly during use.
The purpose of this utility model is achieved in that combined type pitot tube comprises backrest type pitot tube and the fairlead being attached thereto; backrest type pitot tube is stuck in head connector; stretch out at two ends; head connector two-port is offered external thread; one end is connected with protective cover; by backrest type pitot tube head cover in the inner; the other end is connected with extension tube; by backrest type pitot tube afterbody cover in the inner; in extension tube another end, be connected with end cap; in end cap, card has fairlead, and fairlead is connected by silicone tube with backrest type pitot tube.
Owing to carrying out technique scheme, the utility model can be combined into the pitot tube that different length versatility is good.After this pitot tube combination, connecting portion is consistent with other position thicknesses, is convenient for carrying and uses.This pitot tube also has the indication of direction location, holds in the right direction in the time of can guaranteeing to use.Adopt backrest type pitot tube as one-shot measurement original paper, the length of extension rod can length customization as required also can adopt many combinations according to the length needing after combination.Whole thickness of pitot tube after combination is consistent, easy to use, and the connection of pitot tube adopts silicone tube, can in the air-flow below 200 ℃, test in temperature.If will be in the higher environment of the temperature practical flexible steel in flat section tubing that can select hyperthermal material.
Accompanying drawing explanation: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is combined type pitot tube structural representation.
Legend: 1. protective cover, 2. backrest type pitot tube, 3. head connector, 4. silicone tube, 5. extension tube, 6. fairlead, 7. fixed plug, 8. end cap.
Embodiment:
The utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1; the fairlead 6 that combined type pitot tube comprises backrest type pitot tube 2 and is attached thereto; backrest type pitot tube 2 is stuck in head connector 3; stretch out at two ends; head connector 3 two-port are offered external thread; one end is connected with protective cover 1; by backrest type pitot tube 2 head cover in the inner; the other end is connected with extension tube 5; by backrest type pitot tube 2 afterbody covers in the inner; in extension tube 5 another ends, be connected with end cap 8, the interior card of end cap 8 has fairlead 6, and fairlead 6 is connected by silicone tube 4 with backrest type pitot tube 2.Backrest type pitot tube 2 is a kind of standard detecting elements, can be elbow type, also can be BS-1 type.Backrest type pitot tube 2 is two, portion from, convenient connect silicone tube, but can not affect the combination of extension rod.
End cap 8 is stretched out at fairlead 6 two ends, and inside snaps in rubber fixed plug 7 processed, and inner terminal also stretches out fixed plug 7.
The cavity pipe that extension tube 5 is both ends open, one port is offered internal thread, and external thread is offered in another port.Between many extension tubes 5, can spin continuously, can lengthen as required.Extension tube 5, by steel pipe manufacturing, can be made different length as required, but is generally no more than 1.5 meters, to be convenient for carrying, is not also shorter than 1 meter, to reduce combination radical.
During assembling, first the silicone tube of two applicable sizes 4 is inserted in to the afterbody of backrest type pitot tube 2, silicone tube 4 is passed to extension tube 5, and together with one end of extension tube 5 interior screw threads is screwed onto with head connector 3.Extension tube 5 can be carried out many combinations according to the length of need combination.After extension tube 5 combinations, the suitable length of silicone tube 4 intercepting is inserted on fairlead 6, fixed plug 7 is buckled in one end of the male thread of extension tube 5, adjust the direction of fairlead 6 identical with the test lead direction of backrest type pitot tube 2, with end cap 8, fixed plug 7 buttons are extremely arranged in extension tube 5.During test, using extension tube 5 as the sign of measurement direction, with adhesive tape, connecting portion is cemented and prevents that connecting portion screw thread from rotating and cause backrest type pitot tube 2 probe orientation and wind speed direction generation deviation.
Above technical characterictic has formed most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, meets the needs of different situations.
