Description
Technical field
The utility model relates to the liquid-sighting glass that a kind of refrigeration industry is used, and especially a kind of simple in structure, cost is low, liquid-sighting glass easy to assembly.
Background technology
Liquid-sighting glass is parts in the refrigeration system loop, its inside have can variable color indicating piece, when the cold-producing medium in the system circuit during through liquid-sighting glass, tested cold-producing medium contacts with indicating piece, if the water content of cold-producing medium is too high, indicating piece will variable color, has potential safety hazard with prompt system.The mounting means that the liquid-sighting glass indicating piece generally adopts in the prior art as shown in Figure 2, an indicating piece loop bar is set in liquid-sighting glass, indicating piece loop bar top is provided with cavity, indicating piece is sticked in the cavity, mounting spring in the indicating piece loop bar, utilize the elastic force of spring that indicating piece loop bar top is close on the glass lens, the opposite side of indicating piece loop bar is fixed in the locating hole of duct wall.But this mode complex structure, part is many, processing difficulties, the cost height, and also assembly difficulty is big.
The utility model content
The utility model is for solving the complex structure that present liquid-sighting glass exists, and part is many, processing difficulties, and cost height, and the big problem of assembly difficulty and provide a kind of simple in structure, cost is low, liquid-sighting glass easy to assembly.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: liquid-sighting glass is formed by the housing of band pipeline, glass lens that housing top is provided with and near the indicating piece of glass lens etc., be provided with passage between glass lens and the pipeline, passage top is provided with step, step is provided with carriage, the top of carriage is cavity, is provided with leg around cavity, and the bottom of cavity is provided with through hole, glass lens is close at the top, and indicating piece is placed in the cavity.With the ledge structure on the carriage cooperation housing, replaced a plurality of parts of existing structure, not only simplify the structure, made things convenient for processing and assembling, the processing capacity to housing also significantly reduces simultaneously, has improved work efficiency, has reduced cost.
As preferably, the elastic construction that carriage is integrated.Use that elastomeric material is disposable to stamp out carriage, utilize the elasticity of carriage leg, can guarantee that glass lens can be close in the top of carriage.
As preferably, leg evenly distributes around cavity, and its bottom surface is close on the step surface.
As preferably, the size and the indicating piece of cavity are suitable.
As preferably, be provided with sealing device between glass lens and the housing.Sealing device can prevent the leakage of cold-producing medium.
The beneficial effects of the utility model are: it has solved the complex structure that present liquid-sighting glass exists effectively, and part is many, processing difficulties, cost height, and the big problem of assembly difficulty.The utility model is simple in structure, handling ease, and cost is low, and is easy to assembly, and tangible economic benefit is arranged.

The specific embodiment
Embodiment 1
In embodiment 1 as shown in Figure 1, liquid-sighting glass is by the housing of band pipeline, the glass lens that housing top is provided with reaches the compositions such as indicating piece near glass lens, be provided with passage 4 between glass lens 6 and the pipeline 3, passage 4 tops are provided with step 6, step 6 is provided with carriage 1 (seeing Fig. 3 Fig. 4), carriage 1 is the integrated elastic construction of stainless steel punching press, the top of carriage 1 is discoidal cavity 11, the size of cavity 11 and indicating piece 7 are suitable, around cavity, be provided with leg 12, leg 12 is 4, evenly distributes, and its bottom surface is close on 6 on the step, the bottom of cavity 11 is provided with through hole 13, glass lens 6 is close at the top, and indicating piece 7 is placed in the cavity 11, is provided with sealing device between glass lens 6 and the housing 2.
The carriage 1 that embodiment 2 adopts as shown in Figure 5, carriage 1 is the integrated elastic construction of stainless steel punching press, top is discoidal cavity 11, the bottom of cavity 11 is provided with through hole 13, through hole is 7, all the other are identical with embodiment 1.
The indicating piece of liquid-sighting glass is indicated water content in the whole system according to its change color, plays the effect of protection whole system.When liquid-sighting glass uses, tested cold-producing medium flows through the liquid-sighting glass pipeline, cold-producing medium contacts with indicating piece by the through hole of passage with the cavity bottom, see through glass lens and observe, if contained humidity is not high in the cold-producing medium, then indicating piece shows green, if indicating piece shows yellow, the water content that shows tested cold-producing medium exceeds standard, and may work the mischief to system, should in time adopt an effective measure and solve.
