Abstract
The utility model relates to a temperature measuring device for having more on size natural gas line, including the gas pipeline, the back soldering temperature meter sheath that punches on the gas pipeline, the thermometer sheath is the coaxial cylindric thermometer sheath of syllogic, if cylindric thermometer sheath hypomere diameter is D, the middle section diameter then is 1.5D, and upper segment diameter side is 2.0D, and every section sheath external diameter change is excessive by the sloping platform, and the system has the screw thread that connects soon with bimetal thermometer in the thermometer mounting groove of the top of thermometer sheath, and it has the polytetrafluoroethylene gasket to settle on the boss of the bottom of thermometer mounting groove. The device of the utility model is simple in structure, easy to carry out, with low costs can adapt to the natural gas temperature measurement of different pipe diameters, improves the temperature measurement precision of natural gas pipeline greatly, and simultaneously, the sloping platform formula that the external diameter changes is excessive, has effectively compensatied the error in the aperture of punching, simultaneously also convenient welding.
Description
Technical field
The utility model belongs to natural gas line technical field of temperature measurement, specifically a kind of temperature measuring equipment on many sizes natural gas line.
Background technology
Natural gas line can be established usually the bimetallic system cell measuring natural gas temperature, for heavy caliber gas pipeline, normally adopt the method for direct perforate welding temperature meter sleeve pipe, but, the measuring accuracy of thermometer is relevant with the effective extension elongation of reality of thermometer, common bimetallic system cell, effective extension elongation should be not less than 65mm can ensure its measuring accuracy, and the measurement point of thermometer, namely the optimum position of thermometer end should in the center of pipeline, like this, the measuring accuracy of bimetallic system cell just can be accurately, but, current thermometer boss is isodiametric cylinder mode, natural gas line for different-diameter is difficult to the optimum position ensureing thermometer end, cause the error that natural gas temperature is measured.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of temperature measuring equipment on many sizes natural gas line.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of temperature measuring equipment on many sizes natural gas line, comprise gas pipeline, welding temperature meter sheath after punching on gas pipeline, described thermometer sheath is the coaxial cylindric thermometer sheath of syllogic, if cylindric thermometer sheath hypomere diameter is D, stage casing diameter is then 1.5D, epimere diameter side is 2.0D, every section of outer diameter sheath change is excessive by sloping platform, in the head temperature meter mounting groove of thermometer sheath, be shaped with the screw thread spun with bimetallic system cell, the bottom boss of thermometer mounting groove is mounted with teflon gasket.
And described excessive sloping platform inclined-plane becomes 45 degree-55 to spend angle with thermometer sheath axis.
And, outside described thermometer sheath epimere, be shaped with screw thread, spinning setscrew nut on this screw thread.
Advantage of the present utility model and good effect are:
1, the utility model apparatus structure is simple, easy to implement, cost is low, and the natural gas temperature that can adapt to different tube diameters is measured, and greatly improves the temperature measurement accuracy of gas pipeline.
2, to have employed sloping platform formula excessive in external diameter of the present utility model change, and the external diameter of this sloping platform formula excessively not only effectively compensate for the error in aperture that gas pipeline punches, also convenient welding simultaneously.
3, the utility model adopts setscrew nut to regulate the installation site of thermometer simultaneously, and usable range is more extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of temperature measuring equipment on many sizes natural gas line, as shown in Figure 1, comprise gas pipeline 1, gas pipeline punches, the hole of getting is welded with thermometer sheath 2, innovative point of the present utility model is, described thermometer sheath is the cylindric thermometer sheath of three sections of coaxial diameter changes, if cylindric thermometer sheath hypomere diameter is D, stage casing diameter is then 1.5D, epimere diameter side is 2.0D, every section of sheath is outside excessive by sloping platform 6, the head temperature meter mounting groove of thermometer sheath is shaped with the screw thread spun with bimetallic system cell 3, the bottom boss of thermometer mounting groove is mounted with teflon gasket 4, for the air of bottom in seal temperature meter sheath.
In concrete enforcement of the present utility model, described sloping platform inclined-plane becomes 45 degree-55 to spend angle with thermometer sheath axis, and the external diameter of this sloping platform formula excessively not only effectively compensate for the error in aperture that gas pipeline punches, also convenient welding simultaneously.
In concrete enforcement of the present utility model, the length that the length of described thermometer sheath hypomere and thermometer sheath hypomere add stage casing corresponds respectively to the radius of two kinds of natural gas lines the most common, and the length of this structure change ensure that the center of thermometer front end in natural gas line when mounted.
In concrete enforcement of the present utility model, screw thread is shaped with in described thermometer sheath upper outside, spinning setscrew nut 5 on this screw thread, regulate the position of setscrew nut to adapt to the temperature survey of different large scale pipeline when thermometer sheath is installed, but when using setscrew nut location and installation, not only natural gas line is wanted to weld with between setscrew nut, meanwhile, also wants welded seal to ensure to occur without leakage phenomenon between nut location back nut and thermometer sheath.
Claims (3)
