Abstract
The utility model discloses a liquid phase check valve sealing detection tool, which comprises an inflation device, a shell, a backflow prevention device, a pipeline and a water tank, wherein a channel is arranged in the shell, the inflation device is connected with one end of the channel, an A liquid phase check valve outlet to be detected is outwardly connected with one end of the channel provided with the inflation device, the other end of the channel is communicated with the water tank through the pipeline, and the backflow prevention device is arranged between the A liquid phase check valve to be detected and the water tank. The liquid phase check valve sealing detection tool is simple in structure and convenient to operate, greatly improves detection accuracy of the liquid phase check valve, improves whole qualified rate of a chromatographic instrument, reduces depot repair rate and production cost, and improves economic benefits of enterprises.
Description
Technical field
The utility model relates to liquid phase retaining valve field, and the sealing that is specifically related to the liquid phase retaining valve detects frock.
Background technology
Sealing is very important quality index of chromatographic liquid phase retaining valve.At present liquid phase retaining valve performing leak test is mainly tested examination by the method for blowing in the valve with rubber pipette bulb, and precision is low, and the operator can only differentiate with feeling by rule of thumb, reliability is low, make the qualification rate of chromatograph integral body low, depot repair rate height, production cost is higher.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of liquid phase retaining valve sealing and detects frock, can solve the method detection sealing that prior art is blown in the liquid phase retaining valve with rubber pipette bulb, the problem that precision and reliability are low.
The utility model is achieved through the following technical solutions:
Liquid phase retaining valve sealing detects frock, comprise aerating device, housing, anti-backflow device, pipeline, water tank, be provided with passage in the described housing, described aerating device is connected with passage one end, A liquid phase retaining valve outlet to be detected outwards is connected in an end of aerating device place passage, the other end of described passage is by the pipeline connection water tank, and described anti-backflow device is arranged between the A liquid phase retaining valve and water tank to be detected.
The further improvement of the utility model scheme is that aerating device is syringe.
The further improvement of the utility model scheme is that anti-backflow device is the good B liquid phase retaining valve of sealing.
The utility model advantage compared with prior art is:
Simple in structure, easy to operate, improved the detection accuracy rate of liquid phase retaining valve greatly, improved the qualification rate of chromatograph complete machine, reduced depot repair rate and production cost, improved economic benefit of enterprises.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Liquid phase retaining valve sealing as shown in Figure 1 detects frock, comprise syringe 1, housing 3, good B liquid phase retaining valve 4, pipeline 5, the water tank 6 of sealing, be provided with passage in the described housing 3, described syringe 1 is connected with passage one end, A liquid phase retaining valve 2 outlets to be detected outwards are connected in an end of syringe 1 place passage, the other end of described passage is by pipeline 5 joining water box 6, and the good B liquid phase retaining valve 4 of described sealing is arranged between the A liquid phase retaining valve 2 and water tank 6 to be detected.
The passage that A liquid phase retaining valve 2 to be detected is put into housing 3 is tightened with joint, again syringe 1 is connected in the passage of housing 3 and squeezes into air, air enters water tank 6 by pipeline 5, judges retaining valve performance quality according to size, quantity and the airflow direction of bubble.
Concrete decision method is:
Excellent: as not have bubble to emerge;
Very: number of bubbles 1-4 p.s. and airflow direction are 0.5-1MM for the straight line diameter;
Qualified: number of bubbles 5-8 p.s., diameter is 1-1.5MM;
Defective: number of bubbles p.s. is greater than 8 and loud effluent stream direction instability.
