Abstract
The utility model discloses a ceramic tube used for a water vapour plasma spray gun including ceramic tube bodies, Wherein outer tube wall and intraductal hollow body of the ceramic tube bodies are all circular stepped, the hollow body is divided into a large circular hole and a small circular hole, the ceramic tube bodies are symmetrically installed in an evaporator pipe, the preposed ceramic tube body is a first ceramic tube body, the postposed ceramic tube body is a second ceramic tube body, an outer circular table of the second ceramic tube body expose the evaporator pipe into a water tank directly, and the internal diameter of the small circular hole satisfies the requirement of cathode rod clearance fit. The ceramic tube used for water vapour plasma spray gun can ensure the concentricity of the cathode rod and the evaporator, and is also helpful for releasing the heat on the cathode assembly and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of parts of portable water vapour plasma gun, is specifically related to a kind of earthenware of water vapour plasma gun.
Technical background
Water vapour plasma gun of the prior art and power supply main frame match, and can finish basic functions such as metal or nonmetallic cutting and welding.Straight tube shape insulation tube is indispensable parts in the water vapour plasma gun, and it is shaped as book wall straight tube (see figure 1), installs between spray gun inner cathode assembly and evaporimeter.At high temperature, under the moist environment, to increase between cathode assembly and the evaporimeter under the voltage condition, straight tube shape insulation tube plays the isolated insulation effect between cathode assembly and the evaporimeter that makes.Insulation tube adopts quartz or pottery to make usually.Existing straight tube shape insulation tube internal diameter is bigger, needs to increase other parts and cooperates the concentricity that could guarantee to be installed in the cathode rod in the insulation tube and be installed in the outer evaporimeter of insulation tube.And concentricity is crucial for the water vapour plasma gun, wants error then directly to have influence on water vapour plasma gun quality slightly.In addition, this straight tube shape insulating ceramics pipe is sealed in the evaporimeter, and heat can't discharge on the cathode assembly.
Summary of the invention
At problems of the prior art, the purpose of this utility model is to provide a kind of earthenware of water vapour plasma gun, and it can guarantee the cathode rod in the cathode assembly and the concentricity of evaporimeter, can also help to discharge the heat on the cathode assembly.
The utility model is the technical scheme that its purpose of realization is taked: a kind of earthenware of water vapour plasma gun, comprise the earthenware body, ducted body in described earthenware body outer tube wall and the pipe is all rounded step-like, and described ducted body is divided into big hole and small sircle hole two parts; Described earthenware body symmetry is installed in the evaporator tube, and preposition earthenware body is the first earthenware body, and rearmounted earthenware body is the second earthenware body, and the outer round platform of the described second earthenware body exposes evaporator tube and directly enters water tank; Described small sircle hole internal diameter satisfies and the requirement of cathode rod matched in clearance.
Described earthenware body outer tube wall is the two stage steps shape, and it is step-like that the intrinsic ducted body of described earthenware is one-level.
The beneficial effects of the utility model: can guarantee the concentricity of cathode rod and evaporimeter, can also help to discharge the heat on the cathode assembly, and cost of manufacture be low.

The specific embodiment
Referring to Fig. 2-4, the utility model comprises earthenware body 1, and earthenware body outer tube wall is rounded step-like, is provided with two stage steps, makes outer tube wall form outer round platform 11, middle round platform 12 and interior round platform 13.Ducted body in the earthenware is one-level step cutting pattern shape, and ducted body is divided into big hole 14 and small sircle hole 15 two parts.
Fig. 5 assembles schematic diagram for the utility model in the water vapour plasma gun.Two earthenware body symmetries are installed in the evaporator tube 2, and the interior round platform 13 of the first earthenware body 1-1 and the second earthenware body 1-2 docks mutually.Cathode rod 3 is inserted in two earthenware bodies.Because the small sircle hole internal diameter and the cathode rod matched in clearance of earthenware make evaporator tube 2, earthenware body and cathode rod 3 threes combine like this and just can realize with one heart.Preposition earthenware body is the first earthenware body 1-1, and rearmounted earthenware body is the second earthenware body 1-2.The outer round platform 11 of the second earthenware body exposes evaporator tube and directly enters water tank 4.Cathode taps is positioned at big hole 14 places of the first earthenware body 1-1.Cathode rod passes the hollow body portion of the first earthenware body 1-1 and the second earthenware body 1-2, and with small sircle hole 15 matched in clearance.Requirement that the big hole internal diameter of the second earthenware body satisfies and the back seal cover closely cooperates.
Length of the present utility model is about 1/2 of original earthenware size, and thickness of pipe wall increases to 3mm by original 1mm.Can a stripping forming, not fine finishining again, processing charges reduce, and yield rate improves.Two earthenware body symmetries are installed in the evaporator tube 2, and the outer round platform of the first earthenware body 1-1 guarantees that cathode taps and evaporimeter do not discharge.The outer round platform of second earthenware exposes evaporator tube and directly enters water tank, the heat of cathode assembly can be transmitted in the outer tank.Promptly prolong the service life of cathode assembly, improved the thermal efficiency again.Earthenware small sircle hole 1 and cathode rod diameter match and guarantee the concentric of cathode rod and evaporimeter.
Claims (2)
