Abstract
The utility model discloses one kind from aspirator vacuum plug, it is related to vacuum and blocks field.It is described in the utility model from aspirator vacuum plug, including a column type cock body, side is equipped with seal groove, has sealing ring in slot；Its both ends is respectively equipped with push-and-pull interface and adsorption tank.It equipped with room temperature getter in the adsorption tank, does not need to activate, residual gas existing for vacuum space is evacuated in a manner that room temperature adsorbs after closure, so as to extend holding time for vacuum environment, improves the service efficiency of vacuum equipment.
Description
Technical field
The utility model is related to vacuum to block field, is related specifically to a kind of from aspirator vacuum plug.
Background technology
The general conventional vacuum for applying to vacuum thermal insulation low temperature container, vacuum insulated piping and the closure of vacuum equipment vacuum is blocked up
Head only has sealed knot effect.This kind of vacuum equipment in use for some time, inner vacuum state can due to material outgassing,
The reasons such as Micro blazed-grating gas, the performance of the adsorbent decline of internal installation or failure are destroyed, and are eventually led to vacuum equipment and are not achieved
The requirement of vacuum insulation and fail.For some huge vacuum installations and large-scale fixed container, the transportation cost of depot repair is high,
Realize that possibility is small, and field maintenance can not meet the skill equipment Requirement and process specifications vacuumized, maintenance effect is poor.
Utility model content
The technical problem to be solved by the present invention is to provide one kind from aspirator vacuum plug, can be taken out in vacuum equipment true
Sky is persistently evacuated after blocking so that the equipment inner vacuum environment survival time lengthens, and improves the practical efficiency of vacuum equipment, saves
The cost of equipment maintenance of enterprise.
Technical solution is a kind of from aspirator vacuum plug used by the utility model solves its technical problem, including cylindricality
Cock body, the cock body side are equipped with two seals slot, and one end of the cock body is equipped with push-and-pull interface, and the other end of the cock body is set
There is adsorption tank, getter is housed in the adsorption tank.
Preferably, in the seal groove equipped with sealing ring, the bleeding point of the sealing ring and vacuum equipment fits closely.
Preferably, screw thread is equipped on the inside of the push-and-pull interface, the screw thread blocks tooling for connecting.
Preferably, the getter is normal temperature type getter, and the normal temperature type adsorbent does not need to activate, in vacuum environment
Middle gulp capacity is big.
The utility model has the beneficial effect that described：
1st, the utility model uses normal temperature type getter, can play air-extraction function after vacuum equipment vacuumizes closure,
Continue to be evacuated residual gas existing for vacuum space in a manner that room temperature adsorbs, during so as to extend the maintenance of vacuum environment
Between, improve the service efficiency of vacuum equipment.
2nd, the utility model can coordinate it using tooling, it can be achieved that the live on-line maintenance of vacuum equipment, also improves and set
Standby service efficiency more reduces the maintenance cost of equipment.After a period of use, vacuum interlayer can be inevitable for vacuum equipment
There is the phenomenon that vacuum constantly deteriorates in ground, and when needing to safeguard, only needs to change described in the utility model from aspirator vacuum plug
, it is more simple and convenient than traditional maintenance mode.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining that this practicality is new
Type is not used to limit the utility model.
As shown in Figure 1, one kind described in the utility model, from aspirator vacuum plug, including column type cock body 1, side is equipped with
Two seals slot 2, one end of cock body 1 are equipped with push-and-pull interface 3, and the other end is equipped with adsorption tank 4, getter is housed in adsorption tank 4.
In the utility model, sealing ring 5 is housed in seal groove 2, the bleeding point 10 of the sealing ring 5 and vacuum equipment is tight
Closely connected conjunction.
In the utility model, 3 inside of push-and-pull interface is equipped with screw thread, and the screw thread blocks tooling for connecting.
In the utility model, getter is normal temperature type getter, and getter can be three kinds of structures.
【Embodiment 1】
As shown in Fig. 2, in the utility model, getter can be piece type getter 6, be loaded into adsorption tank 4, adsorb
The section of slot 4 is similar to C-shaped channel, and notch inwardly wraps, for fixinig plate type getter 6.
【Embodiment 2】
As shown in figure 3, in the utility model, getter can be coating type getter 7, be applied to adsorption tank 4
Surface.
【Embodiment 3】
As shown in figure 4, in the utility model, getter can be granular pattern adsorbent 8, be loaded into adsorption tank 4.Make
Granular pattern adsorbent 8 is fixed with square 9, the edge card of square 9 is at 4 notch of adsorption tank.
【Embodiment 4】
Vacuum equipment is blocked from aspirator vacuum plug using described in the present embodiment, need to will only block tooling and push-and-pull interface
One end equipped with adsorbent, after the completion of vacuumizing, is filled in the bleeding point 10 of vacuum equipment, then unload closure tooling by 3 connections.
After closure, normal temperature type getter can play air-extraction function, continue to there is vacuum space in a manner that room temperature adsorbs
Residual gas be evacuated, so as to extend the service life of vacuum equipment.
Although to the utility model, illustrative specific embodiment is described above, in order to the art
Technical staff is it will be appreciated that the utility model, but the utility model is not limited only to the range of specific embodiment, to this technology
