Abstract
The utility model discloses a kind of helium mass spectrum leak detection suction gun preventing clogging up device, described suction gun preventing clogging up device includes cylindrical column casing with holes, inner cylindrical tube, arc elastic card and circular ring plate.Arc elastic card and inner cylindrical tube are linked together, and inner cylindrical tube and cylindrical column casing with holes are connected on circular ring plate；The diameter of cylindrical column casing with holes is equal with the outside diameter of circular ring plate, and the diameter of inner cylindrical tube is equal with the outside diameter of circular ring plate；Cylindrical column casing, inner cylindrical tube, arc elastic card and circular ring plate use stainless steel material；The device, which is installed to, can prevent the waste heat of workpiece from burning out suction gun suction pipe on suction gun, so that suction pipe blocks, play anti-clogging effect；The apparatus structure is simple, convenient manufacture, saves the clear rifle time, improves production efficiency.
Description
Technical field
The utility model belongs to leakage detecting instrument field, more particularly to helium mass spectrum leak detection instrument field, and in particular to a kind of helium
Mass spectrum leak detection suction gun preventing clogging up device.
Background technology
At present, it is that plastic material makes with the suction gun suction pipe and suction nozzle of helium mass spectrometer leak detector, in leak detection, if suction gun
Contacted accidentally with suction nozzle the welding region that has surplus heat will scaling loss suction nozzle so that suction nozzle blocks.At this moment, typically there are two kinds of processing sides
Method：When cleaning suction nozzle, but the plenty of time can be taken, reduce productivity ratio；Second, suction nozzle is changed, but suction nozzle cost is higher, increases
Add production cost.In order to solve helium mass spectrum leak detection suction gun blockage problem, a kind of suitable helium mass spectrum leak detection suction gun anti-clogging is designed
Device is very necessary.
Utility model content
The purpose of this utility model is to design a kind of helium mass spectrum leak detection suction gun preventing clogging up device.
Particular technique content of the present utility model is：A kind of helium mass spectrum leak detection suction gun preventing clogging up device, including it is with holes outer
Cylindrical drum, inner cylindrical tube, arc elastic card and circular ring plate；Arc elastic card and inner cylindrical tube link together, inner cylindrical tube and
Cylindrical column casing with holes is connected on circular ring plate；The diameter of cylindrical column casing with holes is equal with the outside diameter of circular ring plate, inner circle
The diameter of column casing is equal with the outside diameter of circular ring plate.
Cylindrical column casing, inner cylindrical tube, arc elastic card and circular ring plate use stainless steel material.
The beneficial effects of the utility model are：The utility model is simple in construction, is easy to manufacture, and material therefor is conventional material
Material, cost is low, and anti-clogging effect is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
It is further described with reference to the accompanying drawings and examples to originally practical.
As shown in figure 1, a kind of helium mass spectrum leak detection suction gun preventing clogging up device, including cylindrical column casing 1 with holes, inner cylindrical tube
3rd, arc elastic card 2 and circular ring plate 4；Arc elastic card 2 and inner cylindrical tube 3 link together, inner cylindrical tube 3 and with holes cylindrical
Column casing 1 is connected on circular ring plate 4；The diameter of cylindrical column casing 1 with holes is equal with the outside diameter of circular ring plate 4, inner cylindrical tube 3
Diameter is equal with the outside diameter of circular ring plate 4.
Cylindrical column casing 1, inner cylindrical tube 3, arc elastic card 2 and circular ring plate 4 use stainless steel material.
Inner cylindrical tube 3 and arc elastic card 2 are enclosed on the suction pipe of helium mass spectrum leak detection suction gun, and inner cylindrical tube 3 plays guiding and made
With arc elastic card 2 plays fixation；There is aperture conveniently to observe suction gun suction pipe and inner cylindrical tube 3 and arc on cylindrical column casing 1
The rigging position of shape elastic card 2, the end of holding suction gun suction pipe is with the openend of cylindrical column casing 1 at a distance of 5mm or so；When leak detection when with
Detection position contact will not also burn out suction gun suction nozzle, play anti-clogging effect.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than it is limited
System.Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that；
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution can not be made to depart from various embodiments of the utility model skill
The spirit and scope of art scheme.
