Abstract
The utility model discloses a kind of hard sealing screw thread three-way ball valves, including valve body, gland, lower cover, core, support column, connecting tube, valve rod, hard sealing ring, elastic ring.First interface is threadedly engaged with pipe formation is threaded into, and the inner ring of the connecting tube is equipped with the internal screw thread cooperated with the first screw thread outlet pipe, the second screw thread outlet pipe, and the connecting tube is fixed on third interface by third bolt group, in second interface.Hard sealing screw thread three-way ball valve provided by the utility model can be used using hard seal means on the pipeline of many medium and high temperature media.By the design of connecting tube, in the case where not rotary valve, the first screw thread outlet pipe, the second screw thread outlet pipe is connected to valve body, facilitate attended operation.
Description
Technical field
The utility model relates to hard seal ball valve fields, more particularly to a kind of hard sealing screw thread three-way ball valve.
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.
It, will be in the screw thread of the pipeline precession screw thread ball valve of continuous mounting ball valve in screw thread ball valve.Pipeline is not in some cases
Allow to rotate, this causes certain difficulty to the installation of screw thread ball valve, more obvious for three-way ball valve this problem.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of hard sealing screw thread three-way ball valve,
The technical solution is achieved in that
A kind of hard sealing screw thread three-way ball valve, including it is valve body, gland, lower cover, core, support column, connecting tube, valve rod, hard
Sealing ring, elastic ring.
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 is threadedly engaged with pipe formation is threaded into, and the inner ring of the connecting tube is equipped with to go out with the first screw thread
The internal screw thread that pipe, the second screw thread outlet pipe cooperate, the connecting tube are fixed on third interface, second interface by third bolt group
On.
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 lower cover is fixed on valve body lower portion by the second bolt group, described
Lower cover limitation support column falls off, and the core has L-type internal channel.
The hard sealing ring forms sealing cooperation in the first interface of core, second interface, third interface direction and core,
The hard sealing ring is equipped with bullet type circle backwards to the face at core center.
Hard sealing screw thread three-way ball valve provided by the utility model can be in many medium and high temperature media using hard seal means
Pipeline on use.By the design of connecting tube, in the case where not rotary valve, the first screw thread outlet pipe, the second screw thread are gone out
Pipe is connected to valve body, facilitates attended operation.
Preferably, the consolidation face of the connecting tube and third interface, second interface is equipped with diaphragm seal.
Detailed description of the invention
