Abstract
The utility model discloses a high-temperature hard-sealing fixing ball valve, belonging to the field of valves. The high-temperature hard-sealing fixing ball valve comprises a left body (1), a valve body (2), a ball body (3), a valve base (4) and a valve stem (6), the ball body (6) is fixed on the valve body through the upper valve stem (6) and a lower valve stem (9), and the valve base (4) is sealed with the ball body (3). The high-temperature hard-sealing fixing ball valve can work in complex work environments such as high temperature, high pressure, large caliber and the like.
Description
Technical field
The utility model relates to a kind of high-temperature hard sealing fixing ball valve, especially the fixing ball valve of working under high temperature, high pressure, heavy caliber environment.
Background technique
Have the ball valve that uses now under high-temperature work environment, generally all adopt the floating ball structure, valve seat and spheroid adopt metallic material, but the floating ball structure can not satisfy high pressure, bigbore requirement; The ball valve that under high pressure, bigbore working environment, uses, require to adopt fixedly spherical structure, but existing fixed spherical structure ball valve, the sealing between its valve seat and the spheroid all adopt the O type circle of elastic rubber material, and described O type circle can not bear the working environment of long term high temperature, high pressure.
The model utility content
Technical problem to be solved in the utility model is: a kind of high-temperature hard sealing fixing ball valve that can use under abominable working environment such as high temperature, heavy caliber is provided.
The technological scheme that solves the problems of the technologies described above is: the high-temperature hard sealing fixing ball valve, comprise left body, and valve body, spheroid, valve seat, valve rod, spheroid is fixed on the valve body by upper and lower valve rod, valve seat and ball seal.
In order to be suitable for high-temperature work environment, valve seat and spheroid all adopt metallic material, and at its surperficial coated with hard alloy; Valve seat produces displacement under the pressure medium effect, so form motive sealing between valve seat and valve body, the left body, its sealing realizes by the gasket seal that extraordinary graphite material high temperature resistant, high pressure is made.The fixing of gasket seal promotes the valve seat bracing ring gasket seal being pressed between valve seat and left body, the valve body tightly realized by being distributed on spring on left body and the valve body.
The beneficial effects of the utility model are: the spheroid of high-temperature hard sealing fixing ball valve, be fixed on the valve body by upper and lower valve rod, valve seat can not born the distortion that spheroid is conducted oneself with dignity and produced radial force and produce, the long term seal performance is good, be suitable for the bore scope and reach 2 "～40 ", the pressure-bearing grade reaches 2500LB, and the cemented carbide of surface spraying possesses corrosion-resistant, wear-resistant, erosion resistance; The envelope gasket sheet that is provided with between valve seat and left body and the valve body guarantees the sealing effect excellence under high temperature, high pressure, abominable medium.
Description of drawings
Fig. 1 is a high-temperature hard sealing fixing ball valve cut-away view.
The partial view of Fig. 2 for sealing between valve seat and the valve body.
Be labeled as among the figure: left body 1, valve body 2, spheroid 3, valve seat 4, spring 5, upper valve rod 6, valve seat bracing ring 7, gasket seal 8, lower valve rod 9.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
From accompanying drawing 1, we can see high-temperature hard sealing fixing ball valve of the present utility model, its spheroid 3 is fixed on the valve body 2 by upper valve rod 6 and lower valve rod 9, spheroid 3 can not produce displacement under the pressure medium effect, be applicable to high pressure, bigbore valve, valve seat can not produce distortion because of bearing spheroid deadweight generation radial force yet simultaneously, thereby reaches sealing steady in a long-term; Spheroid 3 and valve seat 4 adopt metallic material, and its surperficial coated with hard alloy is applicable to high-temperature work environment; Valve seat 4 produces displacement under the pressure medium effect, can tightly be attached on the spheroid 3, forms sealing pair and reaches sealing effect; Because of valve seat 4 produces displacement, valve seat 4 just becomes motive sealing with the seal form of left body 1, valve body 2, relies on valve base sealing pad 8 to realize sealing.In order to satisfy high-temperature work environment, the material of described gasket seal adopts extraordinary graphite, the friction ractor of this special type graphite is more much smaller than common carbon, it is 4～8 times of common carbon that its plasticity and doing is drawn intensity, compressive strength is 2 times of common carbon, thereby guarantee the whole bearing capacity of valve, and should special type graphite temperature using scope reach 500 ℃, thereby satisfied the requirement that is used in hot environment.
Referring to Fig. 2, show the device of fixing seal pad.The helical spring 5 promotion valve seat bracing rings 7 that are distributed on left body 1 and the valve body 2 are pressed on valve base sealing pad 8 between left body 1 and valve seat 4, valve body 2 and the valve seat 4, have guaranteed valve seat and valve body excellent sealing ability.
Claims (5)
1. the high-temperature hard sealing fixing ball valve comprises left body (1), valve body (2), and spheroid (3), valve seat (4), valve rod (6), spheroid (3) is fixed on the valve body (2) by upper valve rod (6), lower valve rod (9), it is characterized in that: valve seat (4) and spheroid (3) sealing.
2. high-temperature hard sealing fixing ball valve according to claim 1 is characterized in that: valve seat (4) and spheroid (3) are metallic material; The sealing surface of valve seat (4) and spheroid (3) is coated with cemented carbide.
