Description
Technical field
The utility model relates to a kind of upper-mounting type ball valve.
Background technique
Because China is coal resource big country, and thermal power generation is the main mode of China Power supply, so Chinese at present electric power industry development is rapid and development trend is fine.In generating set, metal seal ball valve just progressively replaces traditional stop valve, be used as feed valve, flying dust valve, Gauge Valves, boiler drain valve, drum outlet valve, superpressure escape cock, economizer drain valve, soot blower separating valve, oil nozzle delivery valve and logical separating valve of major steam line step, require metal seal ball valve energy antiscour, anti-cavitation erosion, heat shock resistance and can be used for frequent operation.At present, domestic large-scale Coal Chemical Industry, electric power, the used valve of contour dangerous, the explosive type fuel gas and dust working environment of petrochemical industry all are to get by two kinds of approach, a kind of is directly from external import, for example water coal slurry is carried and is adopted the ancient technology (TEXACO) of German scholar, the dry coal powder is carried and is adopted shell technology (SHEEL) or German GSP technology, external imported product stability and technology content are higher, but price comparison height, and in case the situation of technical problem or damage occurs, domestic can not the reparation, can form dependence, bring inconvenience to domestic production; Second kind is homemade valve, and the defective of existence is that stability, heat-resisting quantity are relatively poor, and working life is shorter in the working environment of high temperature.
The model utility content
The purpose of this utility model provides a kind of upper-mounting type ball valve, and stability, heat-resisting quantity is better, and price is low, long service life.
For achieving the above object, the technical solution of the utility model is:
A kind of upper-mounting type ball valve, comprise valve body, valve rod, spheroid, valve rod, spheroid are arranged in the valve body, the two ends of spheroid are respectively equipped with valve seat, it is characterized in that: the outside of described valve seat is provided with the adjustment plug screw, be provided with dish spring, cylindrical spring between described valve seat and the adjustment plug screw, be provided with the reservation radial clearance between described dish spring, cylindrical spring, the adjustment plug screw.
According to a kind of preferred construction, spheroid described in the utility model and valve rod are one-body molded; Described dish spring and cylindrical spring are made by exotic material.
According to a kind of preferred improvement structure, be provided with valve seat positioning ring and valve base sealing pad between the internal surface of valve body described in the utility model and the valve seat.
As improvement, be provided with lining between dish spring described in the utility model and the cylindrical spring; Be provided with the seal with buss pad between the internal surface of described lining and valve body.
As further improvement, be respectively equipped with clasp between cylindrical spring described in the utility model and valve seat and cylindrical spring and the seal with buss pad.
The utility model also can be done further improvement, is provided with the cylindrical spring cover between the internal surface of described cylindrical spring and valve seat.
Therefore compared with prior art, the utility model has following beneficial effect:
Therefore the performance of dish spring and cylindrical spring is different in the utility model, can guarantee the sealing under different temperatures, is used for the serviceability temperature scope that whole ball valve can be improved in the adjusting play simultaneously, and stability, heat-resisting quantity are better, long service life; Because it is homemade that all material is, so price is low, be about 1/4 of equal imported product.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Be illustrated in figure 1 as the embodiment of a kind of upper-mounting type ball valve described in the utility model, comprise valve body 1, valve rod 2, spheroid 3, valve rod 2, spheroid 3 are arranged in the valve body 1, the two ends of spheroid 3 are respectively equipped with valve seat 4, the outside of valve seat 4 is provided with adjusts plug screw 7, be provided with dish spring 5, cylindrical spring 6 between valve seat 4 and the adjustment plug screw 7, be provided with the reservation radial clearance between dish spring 5, cylindrical spring 6, the adjustment plug screw 7.
During actual the use, the radial clearance of valve seat 4, spring, adjustment plug screw 7 can be reserved in advance according to the temperature of actual working environment, the axial clearance of spheroid 3, valve seat 4, spring, adjustment plug screw 7 is finished by the pretightening force of spring, adjust the pretightening force of plug screw 7 adjustable valve seats 4, guarantee that spring has enough gaps when high temperature, realize valve switch with the moment of minimum, in and the switch moment that after high temperature expands, increases suddenly of ball valve.
In order to improve heat-resisting quantity, in present embodiment, dish spring 5 and cylindrical spring 6 are made by exotic material.
In order to improve stability, in present embodiment, spheroid 3 and valve rod 2 are one-body molded, are provided with valve seat positioning ring 41 and valve base sealing pad 42 between the internal surface of valve body 1 and the valve seat 4; Be provided with lining 8 between dish spring 5 and the cylindrical spring 6, be provided with seal with buss pad 81 between the internal surface of lining 8 and valve body 1; Be respectively equipped with clasp 9 between cylindrical spring 6 and valve seat 4 and cylindrical spring 6 and the seal with buss pad 81; Be provided with cylindrical spring cover 61 between the internal surface of cylindrical spring 6 and valve seat 4.
More than technological scheme that the utility model embodiment is provided be described in detail, used specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as restriction of the present utility model.
