Abstract
The utility model provides a circumscribed pressure pipe joint of a pressure transmitter for measuring pressure, which is characterized in that an outer sleeve is fixed on a pressure pipe; an outer sleeve round cap is fixed at the head part of the outer sleeve through welding; a hexagonal screw cap with the threads corresponding to those of the outer sleeve round cap is welded on one side of the pressure pipe in the position close to a transmitter joint; a transmitter joint screw cap is arranged at the top end of the pressure pipe; the outer sleeve is connected with the pressure pipe through welding; the diameter of the outer sleeve is two to three times as large as that of the pressure pipe; and a companion flange plate is welded on one side of the pressure pipe in the position close to the transmitter joint and is fixed through fixing bolts. The utility model has the advantages as follow: the pressure pipe joint can be disassembled and assembled for checking at any time and maintained quickly and conveniently, the structure is simple, the manufacturing is easy, the cost lower, and the utility model is economical and practical.
Description
Technical field
The utility model belongs to the nonferrous metallurgy field, measures the circumscribed pressure unit connecting pipe piecing devices of pipeline pressures such as metallurgical furnace, flue, fluid pipeline when relating in particular to non-ferrous metal metallurgy such as copper, lead, zinc.
Background technology
In nonferrous metallurgical process, the transmitter connecting pipe that will be used for the flue gaging pressure usually is directly welded in the tested pipeline outside surface, because of connecting pipe will reach conducting pressure in the flue gas, when under containing moisture and flue dust operating mode, using, plugging fault often appears in connecting pipe, and is difficult for mediation, needs frequent maintenance test, influence the normal use of surveying instrument, cause obstacle to ordinary production.
The problem that prior art exists mainly contain following some:
1) the most of employing of the pressure unit connecting pipe stainless steel of producer's configuration, the very thin difficult welding of tube wall;
2) the connecting pipe caliber is thinner, under the operating mode complicated situation, difficult mediation phenomenon occurs easily stopping up, needs in case of necessity to cut off mediation with cutting tool;
3) be prone to fracture or distortion, influence is used;
When 4) using in pressure vessel or pipeline, also need professional welder's welding when keeping in repair if connecting pipe breaks down, the short time is difficult to recover.
The utility model content
The purpose of this utility model is at problems of the prior art, can solve pressure unit connecting pipe in use easy fracture or distortion and provide, the circumscribed pressure unit connecting pipe joint of a kind of gaging pressure of the problem of difficulty dismounting when occurring stopping up, difficult mediation and difficult welding.
The technical scheme that the utility model adopted has: a kind of circumscribed pressure unit connecting pipe joint of gaging pressure, form by connecting pipe, outer tube, circle cap or flange, six rib nuts, transmitter collar nut, be fixed with outer tube on the connecting pipe, the head of outer tube is welded with outer tube circle cap, be connected to and six consistent prismatic nuts of outer tube circle cap thread near transmitter joint one face down bonding at connecting pipe, there is the transmitter collar nut on the connecting pipe top.Outer tube and connecting pipe are for being welded to connect, and the diameter of outer tube is 2-3 a times of connecting pipe diameter.
The technical scheme that the utility model adopted can also be: be connected to the companion flange sheet at connecting pipe near transmitter joint one face down bonding, the companion flange sheet is fixed by set bolt.
Compared with prior art, the utility model has the advantages that: dismounting inspection at any time, keep in repair efficient and convenient; Simple in structure, easily make; Cost is lower, and is economical and practical.

Fig. 2 is the structural representation of the utility model embodiment 2.
Among the figure: 1 is the transmitter collar nut; 2 is connecting pipe; 3 is six rib nuts; 4 are the circle cap; 5 is outer tube; 6 is the companion flange sheet, and 7 is set bolt.
Embodiment
Embodiment 1: as shown in Figure 1, a kind of circumscribed pressure unit connecting pipe joint of gaging pressure, form by connecting pipe 2, outer tube 5, circle cap 4, six rib nuts 3, transmitter collar nut 1, be fixed with outer tube 5 on the connecting pipe 2, the head of outer tube 5 is welded with outer tube circle cap 4, be connected to and six consistent rib nuts 3 of outer tube circle cap 4 screw threads near transmitter joint one face down bonding at connecting pipe 2, there is transmitter collar nut 1 on connecting pipe 2 tops.Outer tube 5 and connecting pipe 2 are for being welded to connect, and the diameter of outer tube 5 is 2-3 times of connecting pipe 2 diameters.Be applicable to little negative pressure or pressure-fired operating mode.
Embodiment 2: as shown in Figure 2, for some medium-pressure or high pressure site pressure transmitter connecting pipe joints, be connected to companion flange sheet 6 at connecting pipe 2 near transmitter joint one face down bonding, companion flange sheet 6 is fixing by set bolt 7.
Process is: elder generation is at the point position of need gaging pressure, weld one and exceed 2～3 times of stainless-steel tube outer tubes 5 of connecting pipe 2 diameters, and at a band of the head of outer tube 5 welding internal thread circle cap 4, then in the position of transmitter connecting pipe 2 near meter base side 100mm, weld consistent six prismatic nuts 3, get final product screwing in the connecting pipe 2 insertion outer tubes 5 that weld then with outer silk with the round cap thread on the outer tube 5; For the medium-pressure or high pressure position, the companion flange sheet 6 that is welded on outer tube 5 heads be welded on transmitter connecting pipe 2 on corresponding companion flange sheet 6 be connected by set bolt 7 and get final product.
Claims (3)
1. the circumscribed pressure unit connecting pipe joint of a gaging pressure, form by connecting pipe, outer tube, circle cap or flange, six rib nuts, transmitter collar nut, it is characterized in that: be fixed with outer tube on the connecting pipe, the head of outer tube is welded with outer tube circle cap, be connected to and six consistent prismatic nuts of outer tube circle cap thread near transmitter joint one face down bonding at connecting pipe, there is the transmitter collar nut on the connecting pipe top.
