The utility model discloses a globular voltage limiting valve module compares traditional voltage limiting valve module and has improved sealed effect.
Description
Technical field
The present invention relates to a kind of pressure cooker valve body field, particularly the spherical pressure limiting valve assembly of one.
Background technology
Traditional pressure cooker is all provided with pressure limiting valve and blast pipe, described blast pipe is all generally by metal material, and be generally all provided with a conical spool in pressure limiting valve, to be contacted with the steam vent of blast pipe by the taper seat of spool and realize sealing, because conical inclined-plane is straight line, sealing can cannot be realized during disalignment, so sealing effectiveness is bad when spool coordinates with steam vent.
Summary of the invention
(1) technical problem that will solve
The problem to be solved in the present invention to improve the sealing effectiveness of spherical pressure limiting valve assembly.
(2) technical scheme
For solving the problem, the invention provides a kind of spherical pressure limiting valve assembly, comprising valve body and blast pipe; Described valve body is provided with a shell, the bottom of described shell includes an inner chamber coaxial with blast pipe, the top of described inner chamber is provided with a support bar coaxial with it, the top of described support bar is connected with the inside of inner chamber, bottom is provided with a Surface of Sphere, described blast pipe includes a steam vent, and described Surface of Sphere coordinates to contact with the top of steam vent and seals.
In above-mentioned spherical pressure limiting valve assembly, the hole wall of described steam vent is embedded with the sealing ring of a flexible material, and the top sealing with Surface of Sphere that described sealing ring is positioned at steam vent contacts.
In above-mentioned spherical pressure limiting valve assembly, the material of described sealing ring is silica gel or rubber.
In above-mentioned spherical pressure limiting valve assembly, the chamfering between the top of described blast pipe and steam vent is 87 °.
In above-mentioned spherical pressure limiting valve assembly, the bottom of described support bar is embedded with a steel ball, and described Surface of Sphere is the bottom surface of steel ball.
In above-mentioned spherical pressure limiting valve assembly, the bottom of described support bar is provided with a seal bar with Surface of Sphere.
(3) beneficial effect
Spherical pressure limiting valve assembly of the present invention, spool is arranged to steel ball or the seal bar with Surface of Sphere, the sealing ring of silica gel material is set at blast pipe, seals to realize valve body by the contact of Surface of Sphere and sealing ring and blast pipe seals, therefore improve sealing effectiveness.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Embodiment one: as shown in Figure 1, Figure 3 and Figure 4, a kind of spherical pressure limiting valve assembly, comprises valve body 1 and blast pipe 2, described valve body 1 is provided with a shell 11, the bottom of described shell 11 includes an inner chamber 12 coaxial with blast pipe 2, the top of described inner chamber 12 is provided with a support bar 13 coaxial with it, the top of described support bar 13 is connected with the inside of inner chamber 12, bottom is embedded with a steel ball 15, the hole wall of described steam vent 21 is embedded with the sealing ring 22 of a silica gel or elastomeric material, the top sealing with the Surface of Sphere 14 of steel ball 15 that described sealing ring 22 is positioned at steam vent 21 contacts, because sealing ring is flexible material, so the good sealing effect of sealing ring 22 and Surface of Sphere 14, Surface of Sphere 14 instead of traditional taper seat in addition, contact tightr, even if steel ball 15 and steam vent disalignment, also sealing can not be affected, therefore sealing effectiveness is further increased.
Chamfering between the top of above-mentioned blast pipe 14 and steam vent 21 is 87 °, improves sealing effectiveness.
Embodiment two: as shown in Figure 2, the present embodiment is substantially identical with embodiment one, and difference instead of steel ball 15 by a bottom with the seal bar of Surface of Sphere 14, achieves the technique effect of above-described embodiment one equally.
Parts with Surface of Sphere 14 are installed in other words, as long as what the present invention needed to state is bottom all within protection scope of the present invention in the bottom of support bar 13 with the support bar 13 of Surface of Sphere 14.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
