A scroll compressor in which measurement of the temperature of refrigerant flowing in a path is facilitated. The scroll compressor (1) has a housing (11), a compression mechanism (15), and a pipe (71). A space (45) functioning as the path for the refrigerant is provided inside the housing (11). The compression mechanism (15) compresses the refrigerant and discharges it to the space (45) from a discharge opening (41). The pipe (71) extends from the inside of the housing (11) to the outside and has one end (71a) and the other end (71b). The one end (71a) is located at a predetermined position inthe space (45), or more specifically, at a position near the discharge opening (41), and is closed. The other end (71b) is located outside the housing (11) and is open. A measurement device (8) is inserted into the pipe (71) from the other end (71b).

The present invention relates to an optical temperature sensor, comprising: a housing; a light-transmitting unit, installed in the housing, for emitting light transmitted through an optical fiber into an inner space of the housing; and a bimetal device, movably installed in the housing, for varying the amount of transmitted light, wherein the optical temperature sensor is capable of measuring a temperature by using the amount of light, from the light transmitted via the optical fiber, which is shielded through bending due to a change in the temperature of the bimetal device, or using the amount of light, from the transmitted light, which is reflected and received. The optical temperature sensor has a simple structure and is not particularly restricted in terms of installation space.

Provided is a method wherein a first radiance meter (21) is pointed toward an object to be measured and measures radiance with at least two wavelengths through a space in which dust exists and each ofa number of second radiance meters (22) equal to that of one or more objects (51) having a temperature differing from that of the object to be measured (50) is pointed toward the objects and measuresthe radiance with at least two wavelengths through the space, and the temperature of the object to be measured (50), the temperature of the dust and the concentration of the dust are measured from the radiance measured via the first radiance meter (21) and the second radiance meter (22).

The invention relates to a high-efficient anaerobic composting reactor.

A tube type ejector with the function of quickly sucking and spraying anticorrosive paint through servo electrical direct drive comprises a motor stator, wherein the motor stator is electrified to make a motor rotor move, the motor rotor can drive the long shaft of a linear motor to carry out reciprocating motion upwards or downwards so as to drive a piston to move in an ejection tube; the movement speed of the motor rotor can be controlled by controlling the voltage and the current, servo electrical direct drive can be realized, and therefore, it is realized that the ejection speed is adjustable; in addition, the ejection amount and the ejection distance can be controlled by controlling the movement output force of the motor rotor; when the motor rotor moves upwards, the anticorrosive paint can only be ejected out through a multi-hole cover after passing through a second check valve, and the process of spraying the anticorrosive paint is completed; and when the motor rotor moves downwards, an anticorrosive paint chamber will suck the anticorrosive paint from a paint storage through a first check valve and a flow sensor, and the process of sucking the anticorrosive paint is completed. The tube type ejector with the function of quickly sucking and spraying anticorrosive paint through servo electrical direct drive has the advantages of being controllable in ejection amount and ejection speed, simple in structure, easy and convenient to operate and the like.

The utility model discloses a gas water boiler and enables to effectively solve the problems that more holes are needed on the prior gas water boiler to install different components, inside liners are badly damaged, and installation is difficult. The gas water boiler comprises an inside liner, wherein two pressure switches are connected to the inside liner through a connecting pipe, and a temperature probe is disposed on the connecting pipe. The gas water boiler has the advantages that only a hole is formed on the inside liner, two pressure switches and a temperature probe can be arranged on the inside liner, thereby reducing the damage to the inside liner, integrating and simplifying fittings installation, and enabling to accurately measure the temperature of water.

The invention provides a test method for detecting graphitization temperature, which includes selecting raw materials, kneading, molding, roasting, reprocessing, temperature-graphitization degree curve drawing and temperature measurement. After the mixture is mixed in proportion, a batch of calcined blanks with the same diameter and thickness are prepared by kneading, molding and roasting, and a part of the calcined blanks are subjected to graphitization treatment at multiple temperature points, and the temperature-graphitization curve of the calcined blanks is drawn Figure, and then place the rest of the calcined billet in each part of the Acheson furnace for graphitization treatment with the graphite material, and finally deduce the graphitization treatment of this part according to the graphitization degree and temperature-graphitization curve of each part of the calcined billet The final temperature can solve the technical problem that the final temperature of the graphitization treatment of each part in the Acheson furnace cannot be measured, and realize the determination of the graphitization level of the graphitized material in each part of the Acheson furnace.

The present invention relates to a device for checking a leakage of live steam from a steam trap, comprising: a body having a pipe shape having an inlet end portion connected to the steam trap and an outlet end portion corresponding to the inlet end portion, and allowing condensate water of the steam trap to flow in through the inlet end portion so as to be discharged through the outlet end portion; a truncated pyramid part having a structure of which the inside is empty, and formed to protrude from the middle of the body so as to communicate with the inside of the body; a first steam-water separating means formed at the inner surface of the body and separating re-evaporated steam re-evaporated from the condensate water flowing through the body; a second steam-water separating means formed at the inner surface of the truncated pyramid part and separating the re-evaporated steam, which is separated from the water in the first steam-water separating means, rising to the upper part of the truncated pyramid part; and a temperature measuring means provided at the upper part of the truncated pyramid part so as to be positioned inside the truncated pyramid part, and measuring and transmitting, to the outside, the temperature of the upper inside of the truncated pyramid part, thereby checking whether the live steam leaks from the steam trap.
