The injection device comprises an injection tube, a piston arranged in the injection tube in an air-tight contact manner, and a push rod connected with the piston; one end of the syringe for fluid to enter and exit is called as the front end; the front end of the injection tube is provided with a valve communicated with the inner cavity of the injection tube, and the front end of the valve is inserted with a rubber plug which can be pulled out. The utility model is suitable for an insulating oil sample, gas sample and laboratory analysis sample when power equipment analysis is used.
Description
Technical Field
The utility model belongs to the technical field of insulating oil analysis utensil technique and specifically relates to a syringe for insulating oil analysis is related to.
Background
At present, in order to judge the operation condition and the defect development trend of oil-immersed power equipment of a power system, insulating oil sampling analysis needs to be carried out on the oil-immersed power equipment, and in the insulating oil sampling process, a plastic rubber cap is adopted to carry out sealed storage on an injector for sampling. The sample is in the transportation, because atmospheric pressure change, the violent vibration in the transportation and carry out laboratory analysis and carry out the mechanical oscillation in-process, cause easily that the sealed of rubber cap is not hard up, drop even and the sample that causes reveals to cause and can't judge equipment running state, and sealed rubber cap drops the loss easily in the use, be not convenient for preserve.
Meanwhile, the traditional sampling adopts a plastic rubber cap to seal the sample, and because of strict requirements of power system experimental analysis on air tightness, the sealing rubber cap needs to be replaced in the key link of laboratory analysis of any insulating oil sample, so that a large amount of waste of the sealing rubber cap is caused, and the waste plastic garbage generated by using and discarding a large amount of sealing rubber caps made of plastics is difficult to naturally degrade, so that environmental pollution and resource waste are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a sealed and reliable injector for analyzing insulating oil.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
an injector for analyzing insulating oil comprises an injection tube, a piston arranged in the injection tube in a gas-tight contact manner, and a push rod connected with the piston; one end of the syringe for fluid to enter and exit is called as the front end; the front end of the injection tube is provided with a valve communicated with the inner cavity of the injection tube, and the front end of the valve is inserted with a rubber plug which can be pulled out.
Preferably, the valve is a gate valve, a butterfly valve, a ball valve, a stop valve or a plug valve.
Preferably, the valve is connected with the syringe by bonding or thermal welding.
Compared with the prior art, the utility model has the advantages of as follows:
the utility model discloses insulating oil sample, gas sample and laboratory analysis usefulness when can be used to the power equipment analysis. Through setting up the valve, seal the sample, prevent the pollution of external factor to the sample, solve traditional mode and adopt plastics to glue the sealed unreliable of cap to the sample to and plastics glue the environmental pollution and the wasting of resources that the cap used to cause, the utility model discloses a valve can not lose basically, can use repeatedly, keeps the convenience, has that the structure is light and handy, convenient to use's advantage.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention. In the following description, for the sake of clarity of illustrating the structure and operation of the present invention, reference will be made to the accompanying drawings by means of directional terms, but the terms "front", "rear", "left", "right", "up", "down", etc. should be construed as convenient terms and not as limitative terms.
The syringe for analyzing insulating oil shown in fig. 1-3 comprises an injection cylinder 1, a piston 2 disposed in the injection cylinder 1 in airtight contact therewith, and a push rod 3 connected to the piston 2; one end of the syringe 1 for fluid to enter and exit is called as a front end; the front end of the injection tube 1 is provided with a valve 4 communicated with the inner cavity of the injection tube.
As a further improvement, the front end of the valve 4 is inserted with a plug 5 which can be pulled down, the combined form of the plug and the valve can be used for sampling gas samples, and the plug and the valve form two sets of barriers for preventing gas leakage and gas impurity entering, thereby ensuring that gas taking and transportation are safer and more practical. The valve 4 can be directly used for opening and closing for sampling the insulating oil, so that the air tightness of the sample in the processes of transportation and test can be ensured.
In this embodiment, the valve 4 is a butterfly valve, and may obviously be a gate valve, a ball valve, a stop valve, a plug valve, or other common valves. The valve 4 and the syringe 1 can be connected by bonding or thermal welding, obviously, the common connection mode such as threaded connection can also be adopted.
The syringe 1 is mainly 5ml, 10ml, 20ml, 50ml, 100ml in size.
The utility model discloses simple structure, convenient to use, can effectively improve the operating efficiency, guaranteed the representativeness and the accuracy of insulating oil, gas sample, be convenient for extensively popularize and apply. The utility model provides a traditional mode adopts plastics rubber cap to seal the sample, and the sample is in preserving, transportation and test process, and rubber cap is not hard up easily or drop the sealed not tight that causes, the sample pollutes, reveals, the sample distortion that causes then and the unable problem of using.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
