A liquid-cooling device includes multiple water blocks and at least one connection tube. Each of the water blocks has a water incoming end, a water outgoing end and a water-receiving space in communication with the water incoming end and the water outgoing end. The connection tube is disposed between each two water blocks. Two ends of the connection tube are respectively connected with the water incoming end of one of the two water blocks and the water outgoing end of the other water block, whereby the water-receiving spaces of the two water blocks communicate with each other via the connection tube. The connection tube has at least one bellows section between two ends of the connection tube. The liquid-cooling device solves the problems of the conventional liquid-cooling device that when the water block is welded, thermal deformation is produced to cause tolerance and the manufacturing cost is higher.

A raw material supply apparatus includes: a raw material supply path through which a raw material gas is supplied into a processing container; a valve provided in the raw material supply path; a pressure sensor configured to detect an internal pressure of the raw material supply path; a raw material exhaust path connected to the raw material supply path and through which the raw material gas in the raw material supply path is exhausted; an opening degree adjustment mechanism provided in the raw material exhaust path and configured to control the internal pressure of the raw material supply path based on an adjustment of an opening degree of the opening degree adjustment mechanism; and a controller configured to perform the adjustment of the opening degree of the opening degree adjustment mechanism based on a value detected by the pressure sensor.

A temperature-controlling measure for a hydrogenation slurry bed reactor has three control points that are set from low to high: cold hydrogen is injected automatically when the system reaches control point 1; cold oil in injected automatically when the system reaches control point 2; each pressure relief is opened automatically when the system reaches control point 3. The pressure relief point is set before and/or after the circulation pump of the reactor if internal circulation is set in the reactor; the pressure relief point is set at the reactor bottom if the internal circulation is not set; at least one pressure relief valve is set at each pressure relief point.

A thermostatic valve, including: a pressure relief ring capable of moving up and down and disposed in a valve body cavity. In normal conditions, the pressure relief ring is abutted against the outer edge of a first valve seat via a spring. An internal channel capable of being opened or closed via up and down movement of the pressure relief ring is further provided in the valve body cavity; when the pressure of a fluid in the thermostatic valve is excessive, the fluid can drive the pressure relief ring to compress the spring, such that the internal channel is in communication with a third interface to realize simultaneous communication with a first flow channel and a third flow channel.

In a temperature control apparatus for controlling the temperature of a load by supplying high-temperature circulating liquid to the load, a device in which a helical channel portion of a first heat exchange channel through which circulating liquid flows is housed in a second heat exchange channel formed of a channel space in a hollow shell through which coolant flows is used as a heat exchanger for cooling the circulating liquid, cylindrical members are individually fitted on an inflow channel portion and an outflow channel portion connected to opposite ends of the helical channel portion of the first heat exchange channel, and the cylindrical members are each fixed to the shell of the heat exchanger with a weld.

A gas-fired cooking grill and a gas valve assembly for a gas-fired cooking grill are provided. The grill includes a cooking chamber, a plurality of gas burners for heating the cooking chamber, a plurality of first valves each to control flow of a combustible gas to a respective one of the gas burners, a gas intake to receive the combustible gas from a combustible gas source, and a second valve comprising a thermostatic valve portion, the second valve disposed intermediate the gas intake and plurality of first valves and in fluid communication therewith, the second valve configured to receive input from a user for selection between a first cooking mode and a second cooking mode, the second valve routing the combustible gas from the gas intake to the plurality of first valves in the first cooking mode and routing the combustible gas from the gas intake to the thermostatic valve portion in the second cooking mode, the thermostatic valve portion selectively routing the combustible gas to a subset of the gas burners based on a comparison of a desired temperature and an actual temperature of the cooking chamber.

The present invention relates to a beer-making device which allows to produce beer, in which yeast is alive, directly on the ground for sale without expert knowledge and can produce various kinds of beer at once, automatically, cheaply and easily, without the possibility of contamination due to contact with the external environment. The beer-making device according to an embodiment of the present invention may comprise: a chamber in which a keg containing wort is mounted; a cold air supply device for supplying cold air into the chamber; a fermentation device for fermenting the wort contained in the keg mounted in the chamber; a weight sensor for detecting the weight of the keg containing the wort; a fermentation degree-measuring unit for measuring the specific gravity (G) of the keg containing the wort from a change in the weight of the keg containing the wort detected by the weight sensor; and a control unit for controlling the internal temperature of the chamber by controlling the cold air supply device, and for controlling the fermentation of the wort contained in the keg mounted in the chamber by controlling the fermentation device, all according to the specific gravity (G) of the keg containing the wort measured by the fermentation degree-measuring unit.
