Description
Technical field
The utility model relates to the member in a kind of glass evacuated preparation process, especially a kind of negative pressure valve.
Background technique
Due to external environment influence, during the increasing of the gas in conventional negative pressure valve or the component of unclassified stores, can cause local pipeline effective cross section obviously to diminish, even stop up glass and make the equipment in flow process, have a strong impact on the normal use of other connection devices.
Model utility content
For the problems referred to above, the utility model aims to provide a kind of negative pressure valve.
For realizing this technical purpose, scheme of the present utility model is: a kind of negative pressure valve, comprise spool installation cap, rubbery flat gasket circle, spool, valve pocket, sealing rubber ring, spool adjusting screw, described spool is installed cap, rubbery flat gasket circle and spool and is connected successively from top to down, described valve pocket is positioned at the both sides of spool, described sealing rubber ring is between spool, valve pocket, and described spool adjusting screw is connected with valve pocket.
As preferably, described sealing rubber ring between spool, valve pocket, to spool and valve pocket in conjunction with sealing.
As preferably, described valve pocket is positioned at the both sides of spool, and semi-surrounding support is carried out to spool in valve pocket bottom.
As preferably, between described spool adjusting screw and valve pocket, adopt and be threaded.
The utility model relates to the negative pressure valve using in vacuum glass preparation process, has solved the deficiency in tratitional technology, and its valve pocket outside thread is connected with external vacuum pump; Valve pocket internal thread is connected with spool cap outside thread; Spool block plays the effect of decoration, the impact that whether has spool block to there is no need whole using effect.Spool adjusting screw outside thread is connected with spool internal thread, and spool adjusting screw plays the effect of stablizing spool.When vacuum pump exhaust, spool and valve pocket are combined closely, and it is simple to operate, easy to use, and applicability is strong.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the utility model spool and the valve pocket schematic diagram while combining closely.
Embodiment
Below in conjunction with accompanying drawing basis and specific embodiment, the utility model is described in further details.
As shown in Figure 1, a kind of negative pressure valve of the utility model embodiment, comprise spool installation cap 1, rubbery flat gasket circle 2, spool 3, valve pocket 4, sealing rubber ring 5, spool adjusting screw 6, described spool is installed cap 1, rubbery flat gasket circle 2 and spool 3 and is connected successively from top to down, described valve pocket 4 is positioned at the both sides of spool 3, described sealing rubber ring 5 is between spool 3, valve pocket 4, and described spool adjusting screw 6 is connected with valve pocket 4.
As preferably, described sealing rubber ring 5 between spool 3, valve pocket 4, to spool 3 and valve pocket 4 in conjunction with sealing.
As preferably, described valve pocket 4 is positioned at the both sides of spool 3, and semi-surrounding support is carried out to spool 3 in valve pocket 4 bottoms.
As preferably, between described spool adjusting screw 6 and valve pocket 4, adopt and be threaded.
The utility model relates to the negative pressure valve using in vacuum glass preparation process, has solved the deficiency in tratitional technology, and its valve pocket outside thread is connected with external vacuum pump; Valve pocket internal thread is connected with spool cap outside thread; Spool block plays the effect of decoration, the impact that whether has spool block to there is no need whole using effect.Spool adjusting screw outside thread is connected with spool internal thread, and spool adjusting screw plays the effect of stablizing spool.When vacuum pump exhaust, spool and valve pocket are combined closely, and it is simple to operate, easy to use, and applicability is strong.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
