Description
Technical field
The utility model relates to hard seal ball valve fields more particularly to a kind of flange to seal three-way ball valve firmly.
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 80%
More than.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 preferably excellent
Point.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
Lower than 200 DEG C, which limits the use scopes of ball valve.Made on the pipeline of many medium and high temperature media using high molecular material
The hidden danger of failure is had for 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.Current hard seal ball valve
In, the installation of sealing ring and elastic ring is not convenient.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art, provides a kind of flange and seals three-way ball valve firmly,
The technical solution is achieved in that
It includes valve body, flange ring, core core lower shaft, the first bolt group, valve rod, top that a kind of flange seals three-way ball valve firmly
Plate.
The center of three sides of valve body is respectively equipped with circular perforations, and the valve inner bottom surface is equipped with firm banking.
Limiting card is equipped at the top of the core, bottom is equipped with core lower shaft, and middle part is equipped with L shape channel.The core lower shaft and fixed bottom
Seat forms cooperation, and the top plate is fixed by bolts on valve body, and the valve rod is removably consolidated with core, on the valve rod
Under be equipped with limit protrusion be respectively held against top plate and core.
The flange ring is fixed by bolts in the side of valve body for being provided with circular perforations, and design has protrusion on flange ring
Pipe, the protruding tube protrude into circular perforations and form cooperation, and the nearly core end of the protruding tube is equipped with spring groove, solid in the spring groove
Determine spring, hard sealing ring is connected on the spring, the spring and hard sealing ring, which are set between protruding tube and core, to be formed
Sealing.
Flange provided by the utility model seals three-way ball valve firmly, can be in many medium and high temperature media using hard seal means
Pipeline on use.By the design of spring groove in protruding tube, so that spring and hard sealing ring is easy for installation.Three flange rings
On be equipped with spring and hard sealing ring strengthens sealing effect.
Optionally, the spring is helical spring.
Optionally, the spring is disk spring.
