Description
Technical field
The present invention relates to instrument valve technical fields, more particularly to a kind of high split type gauge ball valve of service life.
Background technique
Instrument valve is a kind of pipeline fittings.It is for changing access section and flow direction of medium, and control conveying is situated between
A kind of dynamic device of mass flow.The sealing performance of instrument valve refers to the ability that each sealing position of instrument valve prevents dielectric leakage,
It is the most important technical performance index of instrument valve.
The sealing position of instrument valve has at three: the contact position between two sealing surface of opening and closing element and valve seat；Filler and valve rod and
Stuffing-box is matched and is located；The junction of valve body and valve deck.Wherein the leakage at previous place is called interior leakage, that is, usually said pass
Not tight, it will affect the ability of instrument valve truncation medium.For block valve class, interior leakage does not allow.Afterwards at two
Leakage is called leakage, i.e., medium from valve internal leakage to valve outside.Leakage will cause loss of material, pollutes environment, can also make when serious
At accident.
Ball valve is one kind of pipeline valve, and opening and closing element (sphere) is driven by valve rod, and rotate around ball valve axis
Valve.Also it can be used for the adjusting and control of fluid, wherein the metal of sealing V-type ball valve its V-type core and pile-up welding hard alloy firmly
There is very strong shearing force, the medium especially suitable for fibre-bearing, small solid pellet etc. between valve seat.
And multi-pass ball valve not only can flexibly control the interflow of medium, the switching for shunting and flowing on pipeline, while can also
It closes any channel and other two channel is made to be connected.This class valve should be generally horizontally mounted in the duct.Ball valve is according to drive
Flowing mode is divided into: pneumatic ball valve, electrical ball valve, manual ball valve.
Currently, the Chinese patent of Publication No. CN203585400U discloses a kind of gauge ball valve comprising have valve body and
Sphere control device on valve body side by side, sphere control device includes set on the intracorporal sphere of valve, valve rod and trigger valve
The control handle of bar rotation, the interior valve seat being equipped with ball seal of valve body；
Pipeline connecting pin outside axial one end of valve body, the other end are external output connector, are equipped at external output connector
The jointing connecting with valve body, jointing extend to the installation gap for being equipped at the intracorporal one end of valve and installing for valve seat, valve
Seat is installed in the installation gap, and the inner hole of valve seat is adapted to the internal diameter of jointing, and jointing is in the week outside valve body
Connecting flange is arranged on face；It is equipped with elasticity between installation gap and valve seat and contradicts device.
Although this gauge ball valve can guarantee that the intracorporal pressure of valve is in equilibrium state always, and installation is more convenient,
The conveying of combustion gas is more stable and smooth, but is often being installed on outdoor due to this valve, controls handle after closing, holds
It is easily miscued by extraneous toy, or is caused to control handle opening by irrelevant personnel maloperation, influence pipeline internal medium
It transports and uses.
Summary of the invention
The technical problem to be solved by the present invention is to often be installed on outdoor due to this valve, control handle is being closed
Afterwards, it is easy to be miscued by extraneous toy, or is caused to control handle opening by irrelevant personnel maloperation, influence to be situated between in pipeline
The transport and use of matter.
In order to solve the above technical problems, the present invention provides a kind of split type gauge ball valve of high service life, including valve body
