Description
Technical field
It the utility model is related to a kind of valve body, more particularly to a kind of ceramic ball valve of heat shock resistance.
Background technology
The appearance of ceramic ball valve, greatly solves the valve of high abrasiveness gas-solid fluid and the fluid liquid containing wear particle
Wear problem, good application is all obtained under the high-low pressure operating mode of such pumped (conveying) medium.At present, common ceramic ball valve is all
It is that valve seat, spheroid use ceramic material, housing uses metal material, seal approach is taken between ceramic trim and metal shell,
This structure is only used for wear-resisting operating mode and deep-etching operating mode.Existing improved method focus mostly in force structure improvement and change
Type, and improvement and the remodeling of sealing.
Such as CN105114650A discloses a kind of high-performance ceramic ball valve, the ceramic ball valve includes valve made of ceramics
Seat, spheroid, valve rod, valve body bushing, stuffing-box, valve seat bush and valve body, bonnet, fastener, handle made of metal material
Seat, drive shaft, filler pressing sleeve, hold-down grid；The valve seat bush is provided with an inner bore of step, the external diameter of the inner bore of step with
Bonnet inner hole connects, and the interior warp of the inner bore of step is provided with multiple tracks bullet with the cylindrical mating connection of valve seat afterbody, its junction
Property sealing ring.By the improvement to ball valve inner sealing, make it possible to preferably adapt to deep-etching operating mode.
But existing ceramic ball valve material mainly uses zirconium oxide, and zirconium oxide thermal shock resistance is poor, thermal shock test
No more than 130 DEG C.If the applying working condition conveying logistics of ball valve institute has the characteristics of interval thermal shock, hot logistics and ball valve ceramic component
Temperature difference is more than 130 DEG C, then ceramic ball valve can not use, and otherwise ceramic component can ftracture because of thermal shock, and serious leak occurs,
And then can not be continuing with, the application of ceramic ball valve is limited, it is may not apply to the control of high temperature long pause thermal material
In system.Therefore, the resistance to sudden heating of ceramic ball valve how is effectively improved, is always the problem of ceramic ball valve engineer applied.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of ceramic ball valve.The ceramic ball valve can reduce or
Eliminate the temperature difference of ball valve ceramic component and thermal shock logistics, make ball valve can heat-resisting logistics impact, prevent from making pottery in the case where hot logistics is impacted
Porcelain component ftractures.
The utility model provides a kind of ceramic ball valve, and it includes valve body, valve rod and the valve element and valve seat that are arranged on valve body,
The valve rod is connected through valve body with valve element, the valve element and valve seat snug fit；It is characterized in that：The ceramic ball valve also includes
Electrical heating controller, temperature sensor and electrical heating sleeve pipe, the electric heating cover pipe sleeve is located at the periphery of valve seat and valve element, described
Temperature sensor and electrical heating casing-contact are connected, and the signal input part of the temperature sensor and electrical heating controller is electrically connected
Connect, the electrical heating sleeve pipe electrically connects with the output port of power source of electrical heating controller.
Thermally protective sleeving is provided between the electrical heating sleeve pipe and valve seat and valve element.
The ceramic ball valve includes first flange, second flange and valve body, and the valve body is set in electrical heating
The periphery of sleeve pipe, the first flange, second flange positioned at the both sides of valve body and are covered in the outside of the valve seat respectively.
The inner edge of the first flange and second flange is recessed to form concave station, and the concave station is covered in the outer of the valve seat
Portion.
The first pad, the second flange and the electric heating cover are provided between the first flange and electrical heating sleeve pipe
The second pad is provided between pipe.
The ceramic ball valve include be arranged on the first self-tightening mechanism between valve seat and first flange and be arranged on valve seat and
The second self-tightening mechanism between second flange, the first self-tightening mechanism include the first sealing ring, the second self-tightening mechanism bag
Include the second sealing ring.
The first self-tightening mechanism also includes the first self-tightening disc spring, and the inner edge of first sealing ring is provided with first annular
Projection, the first self-tightening disc spring are fastened in first annular projection, and the first self-tightening disc spring is located at first flange and valve seat
Between；
The second self-tightening mechanism also includes the second self-tightening disc spring, and the inner edge of second sealing ring is provided with the second annular
Projection, the second self-tightening disc spring are fastened on the second annular protrusion, and the second self-tightening disc spring ring is located at second flange and valve
Between seat.
Be provided with the first elastic seal ring between the first annular raised and first flange, second annular protrusion with
The second elastic seal ring is provided between second flange.
The outer rim of first sealing ring is provided with the 3rd annular protrusion, the 3rd annular protrusion and first annular raised difference
Positioned at the both sides of the first sealing ring, the first ring material filler is provided between the 3rd annular protrusion and valve seat；
The outer rim of second sealing ring is provided with fourth annular projection, and fourth annular is raised to be distinguished with the second annular protrusion
Positioned at the both sides of the second sealing ring, the fourth annular is raised to be provided with the second ring material filler between valve seat.
The valve body sets entrance hole and wire hole, two terminals of the electrical heating sleeve pipe to pass through two electric wires
Electrically connected with the output port of power source of electrical heating controller, two electric wires are each passed through entrance hole and wire hole；The temperature passes
Sensor is connected by sensing electric wire with electrical heating controller, and the sensing electric wire passes through entrance hole or wire hole.
Compared with prior art, it is of the present utility model to have the following advantages that：
（1）Ceramic ball valve of the present utility model, electrically heated mode is introduced in ball valve internal structure, is reduced or eliminated
The temperature difference of thermal shock logistics and ceramic cartridge, and using electrical heating controller control ball valve internal temperature, make ball valve heat-resisting
Logistics is impacted, and prevents that ceramic component ftractures in the case where hot logistics is impacted.
