Energy.
Each limit close-over 2 of the limiting component 3 is disposed as the structure being made by precoated sand material.It is above-mentioned
Structure, limit close-over use precoated sand material, and precoated sand material intensity is high, and high temperature resistant, and gas forming amount is low, and expansion rate is low, defeated and dispersed
Property is good, and release property and anti-stick grittiness are good.Meet the high-intensitive condition of centrifugal casting needs.
The invention further relates to a kind of assembly method of Inner part of water valve sealing ring, the assembly side of the Inner part of water valve sealing ring
The installation step of method are as follows: 1;Sealing ring 14 is processed by the Inner part of water valve sealing ring casting mould;2;In sealing ring 14
Sealing ring threaded portion 19 on smear sealant;3 are clamped on the lug 17 of sealing ring 14 by spanner, and band dynamic seal ring 14 revolves
Turn, the sealing ring threaded portion 19 of sealing ring 14 is screwed with Inner part of water valve and is connect;4 polish off lug 17 by sander, sealing
Circle 14 is reliably screwed with Inner part of water valve to be connect, and the assembly of sealing ring 14 is completed.Above-mentioned assembly method, the special knot based on sealing ring
Structure is realized, when needing for sealing ring to connect with Inner part of water valve, is smeared sealant in sealing ring threaded portion, is then twisted by spanner
It fills on sealing ring to Inner part of water valve, the setting of lug, convenient for easily and reliably tightening sealing ring, and after sealing ring is tightened, leads to
Cross sander and polish off lug so that sealing ring become cirque structure, the lug of protrusion no longer influence Inner part of water valve its
The arrangement of his component, and sealant also solidifies performance sealing function at this time, is improving sealing ring tightness in this way, being achieved that
Meanwhile also effectively improving the installation convenience of sealing ring.
Inner part of water valve sealing ring casting mould of the invention, the size and shape of the sealing ring manufactured as needed, production
Multiple limit close-overs, limit close-over is arranged in bottom cover plate, and limit outer ring and positioning column core are also set up on bottom plate cover board,
Then, outer ring, positioning column core and typewriting casting unit are limited and forms hollow structure, the hollow structure is that is, need to manufacture close
The shape of seal, and casting sealing ring casts solution in backward casting mold cavity, after solution is cooling, that is, forms satisfactory sealing
Coil structures, and threaded portion can form the sealing ring threaded portion along sealing ring inner ring one week arrangement, lug in sealing ring inner peripheral surface
Casting unit 8 then forms the lug of multiple protrusions in the outer ring of sealing ring body.When needing for sealing ring to connect with Inner part of water valve,
Sealant is smeared in sealing ring threaded portion, is then screwed on sealing ring to Inner part of water valve by spanner, the setting of lug, convenient for side
Just sealing ring is reliably tightened, and after sealing ring is tightened, lug is polished off by sander, so that sealing ring becomes circle
Ring structure, the lug of protrusion no longer influence the arrangement of Inner part of water valve other component, and sealant also solidifies performance sealing at this time
Effect, in this way, being achieved that while improving sealing ring tightness, also effectively improves the installation convenience of sealing ring.This hair
Bright Inner part of water valve sealing ring casting mould, structure is simple, convenient and efficient can process sealing ring, effectively improve sealing ring and
Sealing performance between spool, it is ensured that sealing ring for a long time use without falling off, improve sealing ring use reliability with
Service life.
