Description
Technical field
The utility model is related to cutting torch nozzle technical field, especially a kind of spout of plasma arc cutting torch.
Background technology
Cutting torch is the important tool of gas welding, since the ion arc that electrode generates during the use of plasma arc cutting torch is logical
It crosses spout small end and focuses the cutting ion arc for spraying and generating high-energy, therefore the actual use operating mode of spout is often with high temperature, this
Also it has led to spout and is easy loss, service life is short, belongs to expendable part, and the type of cooling of spout is to be gas-cooled more often at present
See, however when electric current reaches 200A or more, spout must then use water cooling, under otherwise the service life meeting of spout is serious
Drop, but spout uses that generally existing sealing effect is bad when water cooling and the water cooling path short-range missile of spout causes cooling effect poor at present
The problem of.
Utility model content
The technical problems to be solved in the utility model is：In order to solve in the prior art spout use water cooling when sealing effect
The problem of the short cooling effect difference in bad and spout water cooling path, now provides a kind of spout of plasma arc cutting torch.
Technical solution adopted by the utility model to solve its technical problems is：A kind of spout of plasma arc cutting torch, packet
Include the spout body of inner hollow, the spout body it is small top and big bottom, the small end of the spout body is extended with forward
Mounting portion, the bottom end end face of the mounting portion offer the center of orifices being connected to spout body inside, the mounting portion upwards
It is outward extended with the shaft shoulder close to one end of spout body, lower sealed groove is offered on the peripheral surface of the mounting portion, under described
Lower seal is provided in sealed groove, the lower seal is located at the lower section of the shaft shoulder, the upper end peripheral surface of the spout body
Sealed groove is offered, sealing ring is provided in the upper sealed groove.
Preferably, the material of the spout body is red copper.
The utility model has the beneficial effects that：Spout the upper end of the utility model plasma arc cutting torch relies on upper sealing ring
It realizes and seals with the component contacted, lower end is realized by lower seal and sealed with the component realization contacted, sealing effect
It is good, and be arranged in the top of lower seal by the way that the fixed shaft shoulder of spout body will be used for, coolant liquid can be extended to the cold of spout
But path to which the cooling effect to spout can be improved, and then promotes the service life of spout.

Detailed description below is used in property meaning processed, and is only asked by appended claims and its equivalent form to limit
The range of the theme of protection.
Embodiment 1
As shown in Figs. 1-3, a kind of spout of plasma arc cutting torch includes the spout body 1 of inner hollow, spout body 1
It is small top and big bottom, the small end of spout body 1 is extended with forward mounting portion 1-1, and the bottom end end face of mounting portion 1-1 opens up upwards
There are the center of orifices 1-11 being connected to 1 inside of spout body, mounting portion 1-1 to be outward extended with axis close to one end of spout body 1
Shoulder 1-12 offers lower sealed groove on the peripheral surface of mounting portion 1-1, lower seal 2, lower sealing is provided in lower sealed groove
Circle 2 is located at the lower section of shaft shoulder 1-12, and the upper end peripheral surface of spout body 1 offers sealed groove, is arranged in upper sealed groove
There is upper sealing ring 3, the material of spout body 1 is red copper.
As shown in figure 4, spout is when being installed on plasma arc cutting torch, it is specific as follows：Plasma arc cutting torch includes interior exhausted
There is end face ring 5-1, spout body 1 to pass through distribution for the bottom end of edge body 4 and the copper pressure cap 5 outside spout body 1, copper pressure cap 5
Device 6 is against on interior insulation body 4, the endoporus of the mounting portion 1-1 through end face rings 5-1 of spout body 1, on mounting portion 1-1 under it is close
Seal 2 is contacted with the inner wall of end face ring 5-1；
By the way that copper pressure cap 5 to be threaded on cutting torch pedestal 7, and the upper surface of the end face ring 5-1 on copper pressure cap 5 is made to support
Spout body 1 is fixed to realize in the firmly lower face of the shaft shoulder 1-12 on spout body 1, and then in the outer wall of spout body 1
Spout water cooling chamber 8 is formed between the inner wall of copper pressure cap 5, the upper end of spout body 1 is close using upper sealing ring 3 and interior insulation body 4
The lower end of envelope, spout body 1 is sealed using the lower seal 2 of mounting portion 1-1 and the end face ring 5-1 of copper pressure cap 5；Wherein, by axis
Shoulder 1-12 is arranged in the top of lower seal 2, can extend the path cooled down to spout, due to shaft shoulder 1-12 and end face ring 5-1
After resisting, shaft shoulder 1-12 therefore also has part coolant liquid to being not fully sealed between the ring 5-1 of end face in spout water cooling chamber 8
It is flow to lower seal 2, to realize the path for extending spout cooling, when cutting torch works, due to the extreme temperatures of spout, slightly
The extension in the cooling path in part is that larger promotion is generated to spout performance.
The above-mentioned desirable embodiment according to the utility model is enlightenment, through the above description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical
Novel technical scope is not limited to the contents of the specification, it is necessary to determine that its is technical according to right
Range.
