Abstract
The utility model discloses a kind of hard seal feed-through ball valve of flange, valve body is provided with installation passage on the propulsion track of core lower shaft.Flange ring is fixed in valve body both ends by bolt cooperation, and hard sealing ring is set between core and flange ring, forms sealing cooperation, and the hard sealing ring is equipped with bullet type circle backwards to the face at core center, and the hard sealing ring and bullet type circle are set in the spring groove of flange ring.The hard seal feed-through ball valve of the utility model flange can be used using hard seal means on the pipeline of many medium and high temperature media, and hard sealing ring is equipped with bullet type circle backwards to the face at core center, reinforce sealing effect.Installation passage auxiliary core on valve body is advanced to it and fixes position.
Description
Technical field
The utility model relates to hard seal ball valve field more particularly to a kind of hard seal feed-through ball valves of flange.
Background technique
This seven kinds of valves of gate valve, shut-off valve, plunger valve, butterfly valve, plug valve, diaphragm valve and ball valve account for about valve total amount at present
80% or more.Wherein ball valve is with fluid resistance is small, it is unrestricted to flow to, opening and closing is rapid and the low comprehensive performance of height is preferable
Advantage.The valve seat of existing ball valve is generally used the manufacture of the high molecular synthetic materials such as rubber, nylon and polytetrafluoroethylene (PTFE), uses temperature
Degree is lower than 200 DEG C, and which limits the use scopes of ball valve.High molecular material is used on the pipeline of many medium and high temperature media
The hidden danger of failure is had as valve seat.The comprehensive performance of ball valve is improved using metal hard sealing structure using temperature and uses the longevity
Life, is the needs of the systems such as chemical industry, petroleum, electric power, metallurgy, concentrated supply of heating in the city and long-distance transport pipes.In ball valve installation process,
The installation of core is emphasis, under normal circumstances more difficult installation.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of hard seal feed-through ball valve of flange,
The technical solution is achieved in that
A kind of hard seal feed-through ball valve of flange include valve body, gland, lower cover, core, support column, hard sealing ring, elastic ring,
Flange ring, valve rod.
Valve rod is fixed on valve body by the gland by the first bolt group, and the valve rod is removably consolidated with core,
Limiting card is equipped at the top of the core, bottom is equipped with core lower shaft, and the support column is set to valve body lower portion, and supports core,
The limited mouth cooperated with core lower shaft is equipped at the top of the support column, the lower cover is fixed under valve body by the second bolt group
Portion, the lower cover limitation support column fall off.The valve body is provided with installation passage on the propulsion track of core lower shaft.
The flange ring is fixed in valve body both ends by bolt cooperation, the hard sealing ring be set to core and flange ring it
Between, sealing cooperation is formed, the hard sealing ring is equipped with elastic ring backwards to the face at core center, and design has spring groove on flange ring,
The hard sealing ring and elastic ring are set in the spring groove of flange ring.
The hard seal feed-through ball valve of flange provided by the utility model, can be in many medium and high temperature media using hard seal means
Pipeline on use, hard sealing ring backwards to core center face be equipped with elastic ring, reinforce sealing effect.Installation passage on valve body
Auxiliary core is advanced to it and fixes position.
Optionally, the core lower shaft is square prominent axis.
Optionally, the elastic ring is disk spring.

Specific embodiment
As shown in Figs 1-4, the revealed a kind of hard seal feed-through ball valve of flange of the utility model, including valve body 1, gland
2, lower cover 3, core 4, support column 5, hard sealing ring 6, elastic ring 7, flange ring 8, valve rod 9.
Valve rod 9 is fixed on valve body 1 by the gland 2 by the first bolt group 21, the valve rod 9 and core 4
It is dismountable to consolidate, limiting card 41 is equipped at the top of the core 4, bottom is equipped with core lower shaft 42, and the support column 5 is arranged
In 1 lower part of valve body, and core 4 is supported, the limited mouth 51 cooperated with core lower shaft 42, institute are equipped at the top of the support column 5
It states lower cover 3 and 1 lower part of valve body is fixed on by the second bolt group 31, the lower cover 3 limits falling off for support column 5.The valve
Body 1 is provided with installation passage 101 on the propulsion track of core lower shaft 42.
The flange ring 8 is fixed in 1 both ends of valve body by bolt cooperation, the hard sealing ring 6 be set to core 4 with
Between flange ring 8, sealing cooperation is formed, the hard sealing ring 6 is equipped with elastic ring 7 backwards to the face at 4 center of core, described hard
Sealing ring 6 and elastic ring 7 are set in the spring groove 81 of flange ring 8.
In specific implementation, the core lower shaft 42 is square prominent axis.
In specific implementation, the elastic ring 7 is disk spring.
Embodiment is only one embodiment of the utility model, for those of ordinary skill in the art, is not being paid
