STRUCTURAL FEATURES
1. Special Seat Design
The floating ball valve adopts the design of flexible seal
ring structure. When the medium pressure is lower, the contact area of
seal ring and ball is smaller. so higher sealing ratio is formed at the place
where the seal ring and ball contact to ensure reliable sealing. When the
medium pressure is higher, the contact area of seal and ball becomes bigger
along with the elastic deformation of seal ring, so the seal ring can endure
higher medium thrust without being damaged.
2. Fireproof Structure Design
In case of fire during the use of valve, the seat ring made of PTFE or other
non-metal materials will be decomposed or damaged under high temperature and
cause higher leakage. The fireproof seal ring is set between ball and seat so
that after the valve seat is burnt, the medium will push the ball rapidly
towards the downstream metal seal ring to form the auxiliary metal to metal
sealing structure, which can effectively control valve leakage. In addition,
the middle flange sealing gasket is made of metal wound gasket, which can
ensure sealing even under high temperature. The fireproof structure design of
floating ball valve conforms to requirements in API 607,spi 6FA,BS 6755 and
other standards.
3. Reliable Sealing Of Valve Stem
The stem is provided with the shoulder at its bottom so that it will not be
blown out by the medium even under the extreme conditions such as abnormal
pressure rise inside the valve cavity, failure of gland plate and etc. In
addition, to avoid leakage after the stem packing is burnt in case of fire, the
thrust bearing is set at the place where the stem shoulder and body contact to
form a reverse sealing seat. The sealing force of the reverse seal will
increase according to the increase of medium pressure, so as to ensure reliable
stem sealing under various pressure, prevent leakage and avoid accident
spreading.
The stem adopts V type packing sealing structure. The V type packing can
effectively change the pressing force and medium force of the gland into the
sealing force of the stem.
According to user requirements, the disc spring loaded packing pressing
mechanism can be adopted to make the sealing of stem packing more reliable.
4. Anti-static Structure
The ball valve is provided with anti-static structure and adopts the static
electricity discharge device to directly form a static channel between the ball
and body or form a static channel between the ball and body through the stem,
so as to discharge the static electricity produced due to friction during the
opening and closing of ball and seat through the pipeline, avoiding fire or
explosion that may be caused by static spark and ensuring system safety.
5. Lock And Misoperation Prevention
The manual ball valve can be locked by a lock when it is at the full open or
full close position. The 90°open and close positioning piece with lock hole is
designed to avoid valve misoperation caused due to handle operation by
non-opearators, and it can also prevent valve opening or closing, or other
accidents caused by pipeline vibration or unpredictable factors. It is very
effective especially for inflammable factors. It is very effective especially
for inflammable and explosive oil, chemical and medical working pipelines or
field tubing. The part on the head of the stem that is installed with the
handle adopts flat design. When the valve is opened, the handle is parallel to
the pipeline, so that the opening and closing indications of the valve are
guaranteed to have no error.
