Problems solved by technology
[0002] In order to expand the scope of use of various general-purpose pressure instruments and be able to adapt to the measurement of high-temperature media, a pressure instrument measurement system composed of a radiator and a general-purpose pressure instrument must be used; at present, spiral tubes are mostly used as heat dissipation and voltage stabilizing devices. However, the spiral tube is not easy to clean, which will affect the normal use of the pressure gauge, and needs to be improved urgently

Embodiment Construction
[0012] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:
[0013] It can be seen from the figure that a high-temperature pressure gauge includes an instrument 1 and a cooling device; the top of the cooling device is provided with a condensate inlet 7, and the lower part of the side wall is provided with a condensate outlet 4; 3 Use the third nut 6 to screw together with the two multi-port and one-hole tubes 8 respectively. Screwed connection, the bottom multi-port one-hole pipe 8 is screwed connected with the pipeline with the second nut 5 .
[0014] The high-temperature medium to be measured enters multiple straight pipes 3 through the lower multi-port one-hole pipe 8, and the condensate enters through the condensate inlet 4 to help the high-temperature medium in the straight pipe 3 cool down. After cooling, the high-temperature medium passes through the upper multi-port one-hole pipe 8 Converge into the instrument ...

The invention provides a high-temperature pressure gauge, which is especially applied to pressure measurement of a high-temperature high-pressure medium. The high-temperature pressure gauge comprises an instrument and a radiating device, wherein the top part of the radiating device is provided with a condensate inlet, and the lower part of the side wall is provided with a condensate outlet; and a plurality of straight pipes are installed inside the radiating device, each straight pipe is connected with two multi-port single-hole pipes in a screwing mode by using third nuts, the multi-port single-hole pipe at the upper part is connected with the instrument in a screwing manner by using a first nut, and the multi-port single-hole pipe at the lower part is connected with a pipeline in a screwing manner by using a second nut. The high-temperature pressure gauge is simple in structure, and ensures accurate pressure measurement of the high-temperature medium; and the radiating device is detachable, and the straight pipes are convenient to clean.
Description
technical field [0001] The invention relates to a pressure gauge, especially a pressure gauge for measuring high temperature. Background technique [0002] In order to expand the scope of use of various general-purpose pressure instruments and be able to adapt to the measurement of high-temperature media, a pressure instrument measurement system composed of a radiator and a general-purpose pressure instrument must be used; at present, spiral tubes are mostly used as heat dissipation and voltage stabilizing devices. However, the spiral tube is not easy to clean, which will affect the normal use of the pressure gauge, and needs to be improved urgently. Contents of the invention [0003] The problem to be solved by the present invention is that the present invention aims at the deficiencies in the above-mentioned technologies, and provides a high-temperature pressure gauge, which uses a plurality of straight pipes as the delivery device to connect the pressure gauge, which is...
