Abstract
The utility model discloses a ball valve for high-temperature and high-pressure. The ball valve comprises a valve body 4, inner blocks 2 which are connected with the valve body 4, pads for ball surfaces 8, 6 which are arranged in the space between the valve body 4 and the inner block 2, and a ball body 7, wherein, the ball body 7 is connected with a valve handle 10, and a press cover 1 which is provided with a passageway for materials is fixedly added to the outsides of the inner blocks. The touching ends of the press cover 1, the inner blocks 2 and the valve body 4 are sealed by flexible graphite pads. The flexible graphite pads are added to the touching ends of the pads for the ball surfaces 8, 6, the inner blocks 2, and the valve body 4. The utility model is suitable for sealing and draining the materials for high-temperature and high-pressure which are lower than 723K and 25MPa. The utility model has the advantages of simple structure, and easy manufacture and assembly.
Description
The utility model belongs to valve, is specifically related to a kind of sealing ball valve that discharges the gas-solid material under High Temperature High Pressure.
In the supercritical extraction process of some High Temperature High Pressure system such as coal, need each parts can both guarantee good sealing property, but under High Temperature High Pressure discharges material and guarantee that the sealing of system is an insoluble problem how both.The High Temperature High Pressure ball valve that can see at present is not that temperature, pressure range are narrow, can only adapt to a high target exactly, maybe can only adapt to high temperature and maybe can only adapt to high pressure, and both can not demand perfection.The High Temperature High Pressure ball valve that Funing County valve plant produces is to compress with home record behind mounting spherical pad, the spheroid successively in a valve body again, and material is directly discharged from home record.The sealing and the heat insulating ability of this ball valve are bad, ooze mixed graphite, crust for alloy etc. because the used sealing material of motive sealing is teflon or teflon, and can distortion under the high pressure of the high temperature of 573K-723K and 10-25MPa being directed at ball valve can't use.
The purpose of this utility model is to overcome the defective of above-mentioned ball valve, provide a kind of sealing good, can be for the ball valve of the frequent use of High Temperature High Pressure system.
High Temperature High Pressure ball valve of the present utility model comprises a valve body and the home record that is connected with valve body, suit ball ring and spheroid successively in valve body and home record, spheroid is connected with valve handle, outside home record, fixedly install a gland again additional with material outlet passage, make material pass through to discharge through gland again behind the home record, seal with the Expanded graphite pad on gland and home record and the end face that valve body contacts.
Be to guarantee the static sealing of spheroid, also can on ball ring and valve body and end face that home record is connected, install the Expanded graphite pad additional.
The ball ring of ball valve is motive sealing, and for satisfying the needs of High Temperature High Pressure, ball ring can select for use the carbon graphite material of diffusion metallizing to make.
High Temperature High Pressure ball-valve structure of the present utility model is simple, and processing and assembling is easy.Install gland on the home record additional and selecting for use special sealing material to realize excellent sealing under the whole ball valve sound state, can satisfy the sealing and the material discharging of the following and High Temperature High Pressure system that 25MPa is following of 723K, solve the difficult problem that this system does not have suitable device the midium or long term.
Below by accompanying drawing embodiment of the present utility model is elaborated.
Accompanying drawing is depicted as according to the High Temperature High Pressure ball-valve structure schematic representation that the utility model proposes.
Flutedly in the valve body 4 be used for placing Expanded graphite pad 9 and ball ring 8, spheroid 7, its center has the material hole to be communicated with the center hole of spheroid 7, home record 2 has the center hole material channel, its bottom end is provided with the groove pad and puts Expanded graphite pad 5 and ball ring 6, spheroid 7 can rotate between ball ring 6 and 8, thereby the sealing of control reaction system and the discharging of material, home record 2 have the outside thread screw thread and connect with valve gap 1, and valve gap 1 seals with Expanded graphite pad 3 with the end face that contacts of home record 2, valve body 4.
Installation of the present utility model is like this: put into graphite pads 9, ball ring 8 in the groove of valve body 4 successively, spheroid 7 places on 8, the groove of the pin of valve handle 10 and spheroid 7 aligned install, adjust the inside and outside pad and the flexible sealing material that tighten valve handle 10 behind the position.Put Expanded graphite pad 5 and ball ring 6 in the groove of home record 2 interior edge faces successively, spheroid 7 leak tests are smashed and compressed to the internal thread that screws in valve body 4 then, Expanded graphite pad 3 with static seal is placed in the concave edge of valve body 4 upper ends at last, screws in the encapsulation situations of the whole ball valve of gland 1 back check.For the temperature that guarantees reaction system does not reduce, can be with the insulation of electrically heated insulation belt parcel on the shell of valve body 4.
Parts such as valve body of the present utility model, home record, valve gap, spheroid can select for use stainless steel material to make, the ball ring that is used for motive sealing adopts diffusion metallizing such as aluminising graphite material to be processed into general turning, the Expanded graphite pad that is used for static sealing is through being molded into, and above-mentioned material is all available at home.
High Temperature High Pressure seal ball-valve of the present utility model is used for the continuous extracting system coal derived fuel oil of brown coal supercritical gas manufacturing process, it is installed in the solid discharge gate place of high-temperature high-voltage reaction device, under the high-temperature and high-pressure conditions of 653K-693K, 12-20MPa, valve shell insulation 573K, the discharging frequency is that the residual coal of discharging solid is 0.5-1.5Kg/ time per hour 1 time, more than 50 switching through 50 hours, the ball valve non-internal leakage, leak outside, open and close flexibly, stable, safety, ball valve is excellent.
