Problems solved by technology

[0005] In addition, in absorption refrigerators, there are cases where a large amount of foreign matter such as iron is contained in the absorption liquid due to long-term use or vacuum opening construction, etc.
The foreign matter such as iron enters the dilute absorption liquid dispensing valve and causes the valve body to lock, and as a result, its performance may not be maintained

[0108] Next, a second embodiment will be described.

[0109] Figure 6 It is a schematic configuration diagram of the absorption refrigerator 200 of the second embodiment. In addition to replacing the locking prevention mechanism 60 ( figure 1 ) except that the locking prevention mechanism 260 is provided, the absorption refrigerator 200 has the same structure as the absorption refrigerator 100 of the first embodiment. Therefore, in Figure 6 in, right with figure 1 The same parts of the shown absorption refrigerator 100 are assigned the same reference numerals, and description thereof will be omitted.

[0110]The lock preventing mechanism 260 has a first supply pipe 261 that supplies the diluted absorbent liquid to the diluted absorbent distribution valve 40 , and a diluted absorbent liquid tank (liquid source) 262 that stores the diluted absorbent fluid. One end of the first supply pipe 261 is welded with the fourth dilute absorption liquid pipe 21D similarly to the firs...

[0116] Next, a third embodiment will be described.

[0117] Figure 7 It is a schematic configuration diagram of an absorption refrigerator 300 according to a third embodiment. In addition to replacing the locking prevention mechanism 60 ( figure 1 ) except that the locking prevention mechanism 360 is provided, the absorption refrigerator 300 has the same structure as the absorption refrigerator 100 of the first embodiment. Therefore, in Figure 7 in, right with figure 1 The same parts of the shown absorption refrigerator 100 are assigned the same reference numerals, and description thereof will be omitted.

[0118] The lock preventing mechanism 360 has a first supply pipe 361 for supplying the coolant liquid to the dilute absorption liquid distribution valve 40 , and a solenoid valve 362 provided in the middle of the first supply pipe 361 . One end of the first supply pipe 361 is welded with the fourth dilute absorption liquid pipe 21D similarly to the first supply pipe 6...

Abstract

Provided is a valve apparatus and an absorption refrigerator capable of stably keeping performance for a long time. The valve apparatus (40) comprises a valve drive part (45) which is is installed in the external part of a pipe (41) where liquid circulates. A valve shaft (44) composing the valve drive part (45) is extended inside the pipe (41). A valve seat (42) abutted against a valve body (43) arranged at a front end of the valve shaft (44) is arranged in the pipe (41). The liquid is allowed to enter into a valve drive part (45) through a gap (delta) of a valve shaft penetration part (141) of the pipe (41) according to an operation of the valve shaft (44), and the liquid in the valve drive part (45) is connected with the same liquid source via a supply pipe (49) having a flow path area larger than the gap (delta) of the valve shaft penetration part (141) of the pipe (41).

Description

technical field [0001] The present invention relates to a valve device and an absorption refrigerating machine using the same, in particular to an absorption refrigerating machine which divides dilute absorption liquid from an absorber into a high-temperature regenerator and a low-temperature regenerator. Background technique [0002] At present, there is known an absorption refrigerating machine, which includes: a high-temperature regenerator, a low-temperature regenerator, a condenser, an evaporator, and an absorber, and the above-mentioned components are connected by piping to form a circulation path of an absorption liquid and a cooling medium respectively (for example, , refer to Patent Document 1). In this type of absorption refrigerator, the diluted absorption liquid formed by the absorption of the cooling medium by the absorption liquid (hereinafter referred to as the diluted absorption liquid) is branched from the absorber to the high-temperature regenerator and the...
