Abstract

The utility model relates to a pipe nipple with filling and temperature-pressure measurement connection pipes, belonging to the technical field of the manufacture of oil-gas gathering and transferring pipelines and tools for measuring the well head temperature and pressure and filling agents. The pipe nipple comprises a measurement component and a pipe nipple; a filling head connection pipe, a thermodetector connection pipe and a pressure measurement gauge connection pipe are mounted on different axial positions of the same pipe nipple; and the pipe nipple is provided with mounting holes for the filling head connection pipe, the thermodetector connection pipe and the pressure measurement gauge connection pipe. The utility model designs a pipe nipple with filling and temperature-pressure measurement connection pipes, wherein the filling head connection pipe, the thermodetector connection pipe and the pressure measurement gauge connection pipe are mounted according to the different axial directions; the utility model solves the problem of complex structure of the prior art, which is caused by that the filling head connection pipe, the thermodetector connection pipe and the pressure measurement gauge connection pipe are arranged on different pipe nipples, thus having the advantages of short length, small volume, light weight, and simple and convenient connection, and meeting the monitoring needs.

Description

The pipe nipple that band filling, thermometric and pressure measurement are taken over
Technical field:
A kind of pipe nipple with filling, thermometric and pressure measurement adapter is used for the test of oil, natural gas gathering line and wellhead temperature, pressure and the filling of medicament, belongs to the manufacturing technology field of oil-gas gathering and transferring pipeline and wellhead temperature, pressure test and medicament filling instrument.
Background technology:
For in the operation process of oil gas in pipeline or well head with chemical injection, and detect pipeline or at the forward and backward oil gas temperature and pressure of well head throttling, usually on oil-gas gathering and transferring pipeline or the forward and backward of wellhead assembly speed control muffler the filling head pipe nipple that has the medicament of can annotating all will be installed, and the thermometric of testing conduit pressure and temperature is surveyed cover; It is to be separately positioned on the different pipe nipples that existing filling head is taken over thermometric pressure measurement cover, is about to the filling head adapter and is connected on the pipe nipple, has flange at the pipe nipple two ends, and the interface that filling head is taken over is set at the middle part of pipe nipple; And the thermometric, pressure measurement that are used for thermometric and pressure measurement are taken over and are connected another pipe nipple, and the flanged terminal pad in pipe nipple two ends is provided with the interface of nozzle for thermometer and gauge manifold at the middle part of pipe nipple; The shortcoming of prior art is: because the pressure of oil-gas gathering and transferring pipeline and well head is all higher, high-pressure natural gas well head particularly, its pressure reaches tens even nearly 100MPa, prior art is taken over filling head and is separately positioned on the different pipe nipples with thermometric pressure measurement cover, cause complex structure, bring a lot of troubles to installation and maintenance, but also increased the cost and the complexity of installing engineering.
Summary of the invention:
The purpose of this utility model is at the deficiencies in the prior art, adopt the scheme of Simplicity in Design, designed and a kind of filling head adapter, nozzle for thermometer and gauge manifold axially have been installed in the pipe nipple that band filling, thermometric and pressure measurement on the same pipe nipple are taken over according to different.
The utility model is achieved in that the utility model comprises test suite and pipe nipple, it is characterized in that: described test suite comprises filling head adapter, nozzle for thermometer and gauge manifold, test suite is mounted on the different axial location of same pipe nipple, and pipe nipple is provided with the installing hole that connects filling head adapter, nozzle for thermometer and gauge manifold;
The upper end of taking over the connecting thread of pipe nipple connecting hole at described filling head is provided with sealing mat, and the lower end of taking over pipe nipple connecting hole screw thread at filling head is provided with the sealing of zero shape circle;
Upper end at the connecting thread of described nozzle for thermometer and gauge manifold and pipe nipple connecting hole is provided with ○Xing Mifengquan, is provided with sealing mat in the lower end of nozzle for thermometer and gauge manifold and pipe nipple connecting hole screw thread;
The utility model is a cylindrical structure, and filling head adapter, nozzle for thermometer and gauge manifold are realized being connected by high pressure screw thread and pipe nipple, and are sealed by sealing mat and ○Xing Mifengquan;
Before the use, the utility model is connected with the adpting flange of pipe-line by the connection screw that two ends are provided with, load onto filling head adapter, nozzle for thermometer and gauge manifold in the connecting hole of on pipe nipple, holding successfully in advance then, after connecting corresponding test and filling pipeline, just can carry out the filling of necessary medicament, the perhaps test of temperature, pressure.
Advantage of the present utility model with beneficial effect is: because filling head adapter of the present utility model, nozzle for thermometer and gauge manifold are according to different axially all being installed on the pipe nipple, so the length of pipe nipple is shorter, can reduce the volume and weight of pipe nipple, also reduced the installation work of a pipe nipple in addition, and because the sealing problem that connection is brought has also just reduced, it is easy to have connection, and operation and observation are convenient, can satisfy the characteristics of monitoring needs.
Description of drawings
Fig. 1 is an outside scheme of installation of the present utility model.
Fig. 2 is the novel broken section mounting structure schematic diagram of this use.
The specific embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model comprises test suite and a pipe nipple 2, test suite is made of filling head adapter 4, nozzle for thermometer 1 and gauge manifold 3, in order to reduce the installation length of pipe nipple 2, the filling head of test suite takes over 4, nozzle for thermometer 1 and gauge manifold 3 be installed on the same pipe nipple 2 different axially on, wherein nozzle for thermometer 1 and gauge manifold 3 be mounted on the pipe nipple 2 same axially on, filling head is taken over 4 and is mounted on the pipe nipple 2 another on axially; In order to seal, be provided with sealing mat 6 in the upper end of filling head adapter 4 and pipe nipple 2 connecting hole screw threads, be provided with zero shape circle in the lower end of filling head adapter 4 and pipe nipple connecting hole screw thread and seal; Upper end at nozzle for thermometer 1 and gauge manifold 3 and pipe nipple 2 connecting hole screw threads is provided with ○Xing Mifengquan, is provided with sealing mat 5 and 7 in the lower end of nozzle for thermometer 1 and gauge manifold 3 and pipe nipple 2 connecting threads; Pipe nipple 2 of the present utility model is columnar structured, and filling head adapter 4, nozzle for thermometer 1 and gauge manifold 3 are realized being connected with pipe nipple 2 by the high pressure screw thread, and by the sealing mat 6,7 and 5 that is provided with respectively, and ○Xing Mifengquan seals;
Before the use, the utility model pipe nipple 2 is connected with the adpting flange of pipe-line by the connection screw that two ends are provided with, then with sealing mat 7 and 5, and ○Xing Mifengquan is enclosed within the lower end of nozzle for thermometer 1 and gauge manifold 3 and pipe nipple 2 connecting threads respectively, with sealing mat 6, and ○Xing Mifengquan is enclosed within the upper end of filling head adapter 4 and pipe nipple 2 connecting threads, respectively filling head adapter 4, nozzle for thermometer 1 and gauge manifold 3 are screwed in the connecting hole of holding successfully in advance on the pipe nipple 2 then, have just finished the installation of test suite;
