Abstract
A sealing structure of an impact air valve comprises a valve core 1, a valve body 2 and a sealing ring 3, wherein the sealing ring 3 is arranged in a ventilation channel 4; the ventilation channel 4 is a ring hole with a horizontal oval cross section; and the cross section of the sealing ring 3 is U-shaped. According to the sealing structure of the impact air valve, the U-shaped sealing ring is placed in the ventilation channel which is the hole with the oval cross section, so that the contact area of the sealing ring is increased, and the optimal sealing effect is achieved. The sealing structure of the impact air valve is simple in structure, convenient to mount and good in sealing effect.
Description
Technical field
The present invention relates to a kind of sealing configuration, particularly relate to a kind of sealing configuration impacting air-valve.
Background technique
At present, the Sealing that the sealing impacting air-valve generally uses is O RunddichtringO, due to the promotion back and forth of spool in the using process impacting air-valve, seal ring easily weares and teares, compress wind is easily caused to be leaked after ring wear, if ring wear is serious, force unbalance can be subject at high pressure wind action lower valve core, valve is easily caused automatically to close or open, and valve in arbitrfary point fixed dwell, if wind-force is excessive, can not can make handle high speed automatic moving energetically, injure operator, there is potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sealing configuration impacting air-valve, improves the sealing effect impacting air-valve.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of sealing configuration impacting air-valve, the seal ring comprising spool, valve body and be arranged in air vent, the annulus hole of described air vent to be cross section be horizontal kidney ellipsoid, described seal ring cross section is U-shaped.
Described seal ring upside down is in air vent, and its opening is towards the center of spool and valve body.
A kind of sealing configuration impacting air-valve provided by the invention, is placed on U-shaped seal ring in the air vent that cross section is oval hole, increases the area of contact of seal ring with this, reaches best sealing effect.Structure of the present invention is simple, easy for installation, good sealing effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural perspective of impacting air-valve.
Fig. 2 is that the present invention is impacting the structure cut-away view in air-valve.
In Fig. 1-2: spool 1, valve body 2, seal ring 3, air vent 4, handle 5.
Embodiment
As shown in figs. 1-2, a kind of sealing configuration impacting air-valve, the seal ring 3 comprising spool 1, valve body 2 and be arranged in air vent 4, described air vent 4 for cross section be the annulus hole of horizontal kidney ellipsoid, described seal ring 3 cross section is U-shaped.
Described seal ring 3 upside down is in air vent 4, and its opening is towards the center of spool 1 and valve body 2.
By a little structure, when operator use handle 5 switching impulse air-valve, spool 1 is in pushing course back and forth, the area of contact of air vent 4 inner seal ring 3 increases, thus reaches better sealing effect, makes the stressed complete equilibrium of spool, air quantity is facilitated to regulate arbitrarily, make spool can stablize stop in arbitrfary point, guarantee that wind-force is stablized, eliminate safe hidden trouble.
Claims (2)
1. one kind is impacted the sealing configuration of air-valve, the seal ring (3) comprising spool (1), valve body (2) and be arranged in air vent (4), it is characterized in that: described air vent (4) for cross section be the annulus hole of horizontal kidney ellipsoid, described seal ring (3) cross section is U-shaped.
2. a kind of sealing configuration impacting air-valve according to claim 1, is characterized in that: described seal ring (3) upside down is in air vent (4), and its opening is towards the center of spool (1) and valve body (2).
