Abstract
The utility model discloses a simple sealing ring valve seat. A first annular groove and a second annular groove are formed in the valve seat in sequence, a supporting sealing ring used as a support is pressed in the first annular groove, the supporting sealing ring protrudes out of the first annular groove, a main sealing ring used as a main seal is pressed in the second annular groove, an annular pressing ring is further arranged, the pressing ring is of an open pressing ring with a cut opening, screw holes are formed in the two sides of the cut opening of the pressing ring, matched inclined-angle overhead hooks are arranged on the valve seat and the pressing ring, the pressing ring is guided into the valve seat through the cooperation of inclined angles of the two inclined-angle overhead hooks and is fastened on the valve seat through the cooperation of the two inclined-angle overhead hooks, the main sealing ring is compressed on the valve seat through the pressing ring, the main sealing ring protrudes out of the second annular groove and the pressing ring, and the positions of the screw holes of the pressing ring are locked on the valve seat through screws. The simple sealing ring valve seat greatly saves the assembling time of the main sealing ring, and has the advantages of being simple in structure, reliable in sealing, convenient to maintain, long in service life and the like.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, and the mounting structure that is specifically related to a kind of soft seal valve seat improves.
Background technique
Soft seal valve seat is generally to install plastic seal ring to reach soft seal effect by various structures and method on valve seat.But current soft seal valve seat ubiquity complex structure, complicated, the shortcoming such as waste time and energy is installed, has higher requirement for step, precision and the dynamics of installing, these shortcomings are urgently to be resolved hurrily.
Model utility content
In order to address the above problem, the utility model provides a kind of plainly-packed seal ring valve seat, and this plainly-packed seal ring valve seat has been saved the installation time of primary seal circle greatly, but also have simple in structure, sealing is reliable, be convenient to the advantages such as maintenance, long service life.
The utility model for the technological scheme that solves its technical problem and adopt is:
A kind of plainly-packed seal ring valve seat, comprise valve seat and seal ring, on described valve seat, be provided with successively first ring connected in star and the second annular groove, in described first ring connected in star, be pressed into as the support seal ring supporting, described support seal ring protrudes from outside described first ring connected in star, in described the second annular groove, be pressed into the primary seal circle as primary seal, also be provided with annular trim ring, described trim ring is to have the opening trim ring that cuts off mouth, the cut-out mouth both sides of described trim ring are provided with screw, described valve seat and trim ring are provided with the oblique angle barb cooperatively interacting, described trim ring is cooperatively interacted and is guided into valve seat and is cooperatively interacted and be fastened on valve seat by two oblique angle barbs by the oblique angle of two oblique angle barbs, described trim ring is pressed in described primary seal circle in the second annular groove of described valve seat, and described primary seal circle protrudes from outside described the second annular groove and described trim ring, described trim ring in described screw place by screw lock on described valve seat.
Preferably, described primary seal circle is delta-ring or O-ring seals.
The beneficial effects of the utility model are: plainly-packed seal ring valve seat of the present utility model is mainly the support seal ring being pressed in first ring connected in star as supporting, in the second annular groove, be pressed into the primary seal circle as primary seal, also be provided with annular trim ring, trim ring is to have the opening trim ring that cuts off mouth, the cut-out mouth both sides of trim ring are provided with screw, valve seat and trim ring are provided with the oblique angle barb cooperatively interacting, the oblique angle of two oblique angle barbs cooperatively interacts and can play leading role, the oblique angle guiding of opening trim ring being aimed on valve seat in the time of assembling one is pressed gently, get final product fastening, with screw, opening is locked afterwards, primary seal circle is pressed on valve seat by trim ring, this structure, greatly save installation time required in the time of fixing primary seal circle, and simple in structure, sealing is reliable, be convenient to safeguard, long service life.
