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 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 seal feed-through ball valve of forging,
The technical solution is achieved in that
A kind of hard seal feed-through ball valve of forging includes valve body, gland, lower cover, core, support column, the first threaded tube, the
Two threaded tubes, connecting screwed tube, valve rod, hard sealing ring, spring.
Described valve body one end by be threadedly engaged with the first threaded tube formed connect, the other end by connecting screwed tube with
Second threaded tube forms connection.The connecting screwed tube inner ring is provided with the internal screw thread with the cooperation of the second threaded tube, described
Connecting screwed tube outer ring is provided with the external screw thread with valve body cooperation, and the nearly core end of the connecting screwed tube is equipped with spring groove.It is described
Limiting card is equipped at the top of core, bottom is equipped with core lower shaft.The hard sealing ring core along valve body extending direction both ends with
Core forms sealing cooperation, and the spring is set in spring groove, resists the hard sealing ring of connection screw thread pipe end.
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 valve body is provided with the channel that auxiliary propulsion core fixes position to it on the propulsion track of core lower shaft, and the lower cover is logical
It crosses the second bolt group and is fixed on valve body lower portion, the lower cover limitation support column falls off.
The hard seal feed-through 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, spring is set in spring groove, resists the hard sealing ring of connection screw thread pipe end, reinforces sealing effect.Valve body
On channel auxiliary core be advanced to its fix position.
Optionally, the core lower shaft is square prominent axis.
