Abstract

The utility model relates to a novel gas insulation X-ray tube capable of feeding liquid for cooling, which comprises a glass ray tube and an anode positioned in the inner cavity of the glass ray tube. A flow guiding tube is arranged in the inner cavity of the anode of the glass ray tube; the diameter of the flow guiding tube is smaller than the diameter of the inner cavity; the lower end nozzle of the flow guiding tube is extended out of the lower end of the anode; the upper end nozzle is extended to the upper part of the inner cavity of the anode; the lower end of the anode is provided with an opening which is mutually communicated with the inner cavity of the anode. Because the utility model uses the structure characteristic, when an X-ray flaw detector works, the novel gas insulation X-ray tube can feed water for cooling the inner cavity of the anode through the flow guiding tube; consequently, the temperature of the anode of the glass ray tube is reduced.

Description

The novel gas insulation X-ray tube that can add the liquid cooling

The utility model relates to a kind of novel gas insulation X-ray tube that adds the liquid cooling.

X-ray flaw detector is a kind of equipment that is used to survey the internal structure of body damage.Known X-ray tube defectoscope is because its anode is a solid construction, and anode will send a large amount of heats and not allow to work long hours when work, must shut down after 5 minutes in work by specification requirement, treats can work after the cooling of X-ray tube anode again.The glassine spool of introducing the x-ray flaw detector of Japanese company of science as China in nineteen eighty-two is this structure.Because this glassine spool is subjected to the restriction of operating time, thereby can not carry out the test of flaw detection of internal structure to thicker object; The 300kvX light pipe defectoscope that has only Belgian " great waves company " to produce at present can even be worked 90 minutes, and maximum penetration thickness can reach 75mm, but its price is up to 480,000 yuan.

The purpose of this utility model just is to provide a kind of anode working time long and simple in structure, the novel gas insulation X-ray tube of cheap added liquid cooling.

The purpose of this utility model can realize by following measure:

The utility model comprises glassine spool and the anode that places its inner chamber, is provided with the mozzle of a diameter less than its intracavity diameter in the anode inner chamber of described glassine spool; The lower end mouth of pipe of this mozzle extends outside the anode lower end, and its upper end mouth of pipe extends to the top of anode inner chamber; Be provided with in the lower end of anode one with the opening of its intracavity inter-connection.

Advantage of the present utility model just is to adopt the anode that has inner chamber, and be arranged on diameter in the anode inner chamber less than the mozzle of its intracavity diameter, when working, x-ray flaw detector can add water cooling by mozzle antianode inner chamber, thereby reduced the temperature of glass rays tube anode widely, improve the stream time of x-ray flaw detector, also reduced the cost of x-ray flaw detector simultaneously.

The drawing of accompanying drawing is described as follows:

Fig. 1 cuts open figure for master of the present utility model.

The utility model is described in further detail below in conjunction with specific embodiment (accompanying drawing):

As shown in the figure, the utility model comprises the anode 5 of glassine spool 3, is provided with the mozzle 6 of a diameter less than its intracavity diameter in anode 5 inner chambers of described glassine spool 3; The lower end mouth of pipe of this mozzle 6 extends outside anode 5 lower ends, and its upper end mouth of pipe extends to the top of anode 5 inner chambers; Be provided with in the lower end of anode 5 one with the opening 9 of its intracavity inter-connection.

Operation principle of the present utility model is as follows:

When the utility model is worked, the lower end mouth of pipe of mozzle 6 is connected with external water pipe 8, at this moment, cooling water cools off through the upper end of mozzle 6 mouth of pipe antianode inner chamber, and flow out, thereby reached the purpose that reduces temperature of anode by being arranged on the opening anode lower end and its intracavity inter-connection 9.
