Abstract
The utility model discloses an air pressure regulating valve which comprises a valve seat. A large sealing ring and an outer valve core are sequentially arranged in the valve seat, a spring blocking ring is sleeved on the outer wall of the lower portion of the outer valve core, a pressing ring, an inner valve core and a small sealing ring are sequentially arranged in the outer valve core, the pressing ring is connected with the inner wall of the outer valve core, a small spring is arranged between the pressing ring and the inner valve core, protrusions are arranged on the outer valve core and the outer wall of the contact end of the large sealing ring, a large spring is sleeved on the outer wall of the outer valve core, and two ends of the large spring respectively abut against the protrusions and the spring block ring. The air pressure regulating valve has the advantages of being ingenious in design, can effectively balance pressure in a box body and pressure in the outside and prevents the box body and accurate instruments from being damaged by unbalanced pressure.
Description
Technical field
The utility model relates to a kind of modulating valve, particularly a kind of air pressure regulator.
Background technique
At present, air pressure regulator generally is not set, still on packaging box, for the packaging box of some splendid attire precision type instrument, just air pressure regulator must be set, because along with the external environment change of elevation, will there be draught head in the packaging box inside and the external world, pressure reduction is big, active force is big, and this masterpiece is used in and will causes instrument to be damaged on some precision type instrument, and acts on the packaging box, make packaging box be in pressured state, can destroy the packaging box sealing system.
The model utility content
The purpose of this utility model just provides a kind of air pressure regulator that can the active balance body inside and outside air pressure.
The purpose of this utility model is to realize by such technological scheme, a kind of air pressure regulator, described air pressure regulator comprises valve seat, in valve seat, be disposed with big sealing ring and outside spool, be arranged with check ring on the outer wall of spool bottom outside, be disposed with trim ring, inner spool and small sealing ring outside described in the spool, described trim ring is connected with outer spool inwall, is provided with little spring between described trim ring and inner spool; Outside described on the spool, and be provided with projection with the outer wall of big sealing ring contact jaw, be arranged with big spring on the spool outer wall outside described, described big spring two ends withstand on respectively on projection and the check ring.
For the ease of and casing between be connected and fixed, the outer wall of valve seat one end is provided with boss, the outer wall of valve seat is provided with locking nut, is provided with O RunddichtringO and packing ring between described boss and locking nut.
Owing to adopted technique scheme, the utlity model has the advantage that structural design is ingenious, manufacturing is easy for installation, adopt it can the active balance casing in and the pressure between the external world, prevented that imbalance owing to air pressure from causing to the damage of casing with to the damage of precision type instrument in the casing.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of air pressure regulator, described air pressure regulator comprises valve seat 1, in valve seat 1, be disposed with big sealing ring 2 and outside spool 9, be arranged with check ring 11 on the outer wall of spool 9 bottoms outside, be disposed with trim ring 3, inner spool 8 and small sealing ring 10 outside described in the spool 9, described trim ring 3 is connected with outer spool 9 inwalls, is provided with little spring 7 between described trim ring 3 and inner spool 8; Outside described on the spool 9, and be provided with projection 13 with the outer wall of big sealing ring 2 contact jaws, be arranged with big spring 6 on spool 9 outer walls outside described, described big spring 6 two ends withstand on respectively on projection 13 and the check ring 11.
Wherein, for the ease of installing and fixing, the outer wall of valve seat 1 one ends is provided with boss 14, and the outer wall of valve seat 1 is provided with locking nut 5, is provided with O RunddichtringO 4 and packing ring 12 between described boss 14 and locking nut 5.
In this use is novel, the spool design of air pressure regulator is become 9 two kinds of inner spool 8 and outer spools.Air pressure acts on the inside and outside spool 8, and they are action under little spring 7 controls just, realizes bidirectional modulation air pressure.
