Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contributes to its enforcement.
As shown in Figures 1 to 5, a kind of gas-liquid separator of the present invention, comprises cylindrical shell 1, is located at the upper end cover 2 of the upper end of cylindrical shell 1, the bottom end cover 3 that is located at cylindrical shell 1 lower end, installing plate 4, air inlet pipe 6, escape pipe 5, U-shaped pipe 7 and net-filter assembly 8.Cylindrical shell 1 is cylindric, both ends open, inner hollow, and bottom end cover 3 is fixed on installing plate 4, and installing plate 4 is fixed for the installation of whole gas-liquid separator.Air inlet pipe 6 is inserted the inside of cylindrical shell 1, and be fixedly mounted on upper end cover 2, the part that air inlet pipe 6 is positioned at cylindrical shell 1 inside is bend pipe, gas-liquid mixed refrigerant enters in gas-liquid separator through air inlet pipe 6 like this, due to the bending design of air inlet pipe 6, utilize biphase gas and liquid flow high speed rotary motion, in the nozzle position whereabouts of condensing; Escape pipe 5 inserts the inside of cylindrical shell 1, and be fixedly mounted on upper end cover 2, the lower nozzle of escape pipe 5 is fixedly connected with the port of export of U-shaped pipe 7, the other end of U-shaped pipe 7 is entrance point, gaseous refrigerant after separating enters from the entrance point of U-shaped pipe 7 U-shaped pipe 7, finally from escape pipe 5, flow out and enter compressor, liquid refrigerant is slowly evaporation in gas-liquid separator, and rear ability to be evaporated can enter compressor through U-shaped pipe 7 and escape pipe 5.The bottom of U-shaped pipe 7 is provided with the outlet that allows inner liquid refrigerant flow out, and after air inlet pipe 6 fixedly mounts on upper end cover 2 with escape pipe 5, and has good sealing between requirement and upper end cover 2, prevents gas leakage.The inside of cylindrical shell 1 respectively arranges a net-filter assembly 8 near the position of upper and lower port, effectively isolates the impurity in cold-producing medium.
The problem existing in order to solve prior art, this gas-liquid separator also comprises pressure relief device 9, this pressure relief device 9 comprises the plug member 91 being located on upper end cover 2, plug member 91 is provided with the steam vent that is communicated with gas-liquid separator inner chamber and external environment condition, in steam vent, be filled with the fusible member 92 that adopts thermal control material to make, this thermal control material refers to the low melting point fusible alloy material that can melt under predetermined temperature effect of the prior art, gas-liquid separator internal temperature raises along with the rising of air pressure, when gas-liquid separator air pressure inside reaches peak, after fusible member 92 dissolves, steam vent is unimpeded, gas-liquid separator inner chamber is communicated with external environment condition, gas is discharged, gas-liquid separator is able to pressure release, prevent that the situation that gas-liquid separator explodes because of superpressure from occurring, protection gas-liquid separator is not damaged.After fusible member 92 dissolves, pull down plug member 91, again change a pressure relief device 9 and be installed on upper end cover 2, just can guarantee that gas-liquid separator can continue to use.
Specifically, because upper end cover 2 is high-pressure sides of gas-liquid separator, this position maximum that is stressed, and bottom end cover 3 need to fill installing plate 4, so pressure relief device 9 will be arranged on upper end cover 2.The end face of upper end cover 2 is provided with the mount pad 10 for plug member 91 is installed.Mount pad 10 is cylindrical, and be weldingly fixed on upper end cover 2 by argon welding, because the end face of upper end cover 2 has certain radian, for the ease of the installation of mount pad 10, the end face of upper end cover 2 is provided with a through hole, and the lower end of mount pad 10 is provided with a step surface accordingly, and insert in through hole the lower end of mount pad 10, position by step surface, thereby the installation of being convenient to mount pad 10 is fixed.
In the time that pressure relief device 9 is installed, in order to ensure fixing reliable, the position contacting between plug member 91 and mount pad 10 is added with thread locking agent.
As shown in Figure 5, the steam vent being located in plug member 91 is provided with one section of internal thread, and the outer surface of fusible member 92 is corresponding is provided with one section of external screw thread, and fusible member 92 inserts in steam vent and is threaded with plug member 91, guarantees that fusible member 92 is fixing reliable in plug member 91, prevents from coming off.Steam vent is towards one end of gas-liquid separator inside, the tapered opening that lower ending opening is open state, and in the time of exhaust, the air inlet openings area of steam vent is large, can improve exhaust velocity, guarantees quick pressure releasing like this.Because fusible member 92 fills up whole steam vent, the bottom of fusible member 92 is the pyramidal structure matching with this tapered opening, and gapless between fusible member 92 and steam vent, has good sealing, can prevent gas leakage.
It is all vertically orientation upward as benchmark definition, to should be appreciated that the use of the described noun of locality should not limit the scope of the application's request protection taking gas-liquid separator air inlet pipe and escape pipe that related upper and lower of foregoing waited the noun of locality.The gas-liquid separator of the present embodiment and the main difference of prior art are to have increased pressure relief device, the prior art of remaining part and operation principle identical.
Below by reference to the accompanying drawings the present invention is exemplarily described.Obviously, specific implementation of the present invention is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or without improvement, above-mentioned design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
