Description

A kind of hard sealing three-way ball valve of forging
Technical field
The utility model relates to hard seal ball valve field more particularly to a kind of hard sealing three-way ball valves of forging.
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.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 sealing three-way ball valve of forging, The technical solution is achieved in that
A kind of hard sealing three-way ball valve of forging includes valve body, gland, lower cover, core, support column, the first screw thread outlet pipe, the Two screw thread outlet pipes, valve rod, hard sealing ring, elastic ring, are threaded into pipe at connecting tube.
The valve body includes the third interface along the setting of same straight line, second interface and perpendicular to the of second interface setting One interface, the first interface are threadedly engaged with pipe formation is threaded into, the inner ring of the connecting tube be equipped with the first screw thread outlet pipe, The internal screw thread of second screw thread outlet pipe cooperation, the connecting tube outer ring are equipped with the external screw thread cooperated with third interface, second interface, institute It states and is equipped with limiting card at the top of core, bottom is equipped with core lower shaft, and the valve body is provided with logical on the propulsion track of core lower shaft Road, the hard sealing ring forms sealing cooperation in the first interface of core, second interface, third interface direction and core, described Hard sealing ring is equipped with bullet type circle backwards to the face at core center.
Valve rod is fixed on valve body by the gland by the first bolt group, and the valve rod is removably consolidated with core, The support column is set to valve body lower portion, and supports core, and the limited mouth cooperated with core lower shaft is equipped at the top of the support column, The lower cover is fixed on valve body lower portion by the second bolt group, and the lower cover limitation support column falls off, and the core has L-type Internal channel.
The hard sealing three-way ball valve of forging 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 bullet type circle, reinforce sealing effect.Channel auxiliary on valve body Core is advanced to it and fixes position.
Optionally, the core lower shaft is square prominent axis.
