Abstract
The utility model discloses a ball body for ball valve, which is mainly composed of a ball 1, a flow passage 2 and a spread groove 3. The spread groove 3 of the ball 1 is embedded with an exclusive valve lever driving groove 4. The ball body for ball valve can use the toughening plastic, nylon etc. material to conveniently product the ball1, the exclusive valve lever driving groove 4 is embedded in the spread groove 3 of the ball1; the intensity of the spread groove 3 of the ball is increased; the service life of the spread groove 3 of the ball1 is prolonged. The ball body for ball valve has the advantages of simple manufacturing technology, low cost, good durability and corrosion resistance, high sealing performance, and long service life.
Description
Affiliated technical field
The utility model relates to a kind of valving, specifically a kind of ball valve spheroid.
Background technique
At present, ball valve is owing to compare with other kinds valve, and it is convenient, rapidly to have a switch, and sealing better, characteristics such as working life is long, and in various tube equipments, be used widely.But sell on the market and the spheroid overwhelming majority of the various ball valves that people often use as cast iron through cast or forging forming after, form through turning, grinding, polishing, plating, the manufacturing process complexity, cost is higher, not wear-resisting, not corrosion-resistant, working life short again.Also have use the stainless steel forging and pressing after, the ball valve spheroid that is made through turning, grinding, polishing, though wear-resisting, good corrosion resistance, long service life, manufacturing process complexity, cost extra-high-speed are only applicable to partly to have in the tube equipment of specific (special) requirements and use.Also have a kind of ball valve spheroid that uses material such as toughened plastic, nylon, but very easily dialled badly by ball valve rod end head because of the connecting groove on the spheroid, working life is extremely short, need often change valve, and fails to be applied always.
Summary of the invention
Higher in order to overcome existing various ball valves with spheroid manufacturing process complexity, cost, not wear-resisting, not corrosion-resistant, the deficiency that working life is short, the utility model provides a kind of ball valve spheroid, has simple, the low production cost of manufacturing process, wear-resisting, good corrosion resistance, sealing is strong, and characteristics such as long service life.
The technological scheme that its technical problem that solves the utility model adopts is: this ball valve spheroid, mainly form by spheroid, runner, connecting groove, and in the connecting groove of described spheroid, be inlaid with special-purpose valve rod allocating slot.Adopt the ball valve spheroid of this structure, can utilize materials such as toughened plastic, nylon, after being made into spheroid very easily, in the connecting groove of spheroid, inlay special-purpose valve rod allocating slot again, increase the intensity of spheroid connecting groove, prolong the working life of spheroid connecting groove, thereby has simple a, low production cost of manufacturing process, wear-resisting, good corrosion resistance, sealing is strong, and characteristics such as long service life.
As the improvement of this model utility, on the spheroid outer wall of this ball valve, plate a coating with spheroid, can further increase the surface flatness of spheroid, improve its wear resistance, corrosion resistance and sealing, prolong its working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the longitudinal section schematic representation of original ball valve with spheroid.
Fig. 2 is the longitudinal section schematic representation of the utility model ball valve with an embodiment of spheroid.
Fig. 3 is the longitudinal section schematic representation of the utility model ball valve with another embodiment of spheroid.
1. spheroids among the figure, 2. runner, 3. connecting groove, 4. special-purpose valve rod allocating slot, 5. coating.
Embodiment
As shown in Figure 1, original ball valve mainly is made up of spheroid 1, runner 2, connecting groove 3 with spheroid.
As shown in Figure 2, the utility model ball valve mainly is made up of spheroid 1, runner 2, connecting groove 3 with spheroid, is inlaid with special-purpose valve rod allocating slot 4 in the connecting groove 3 of spheroid 1.Adopt the ball valve spheroid of this structure, can utilize materials such as toughened plastic, nylon, after being made into spheroid 1 very easily, in the connecting groove 3 of spheroid 1, inlay special-purpose valve rod allocating slot 4 again, increase the intensity of spheroid 1 connecting groove 3, prolong the working life of spheroid 1 connecting groove 3, thereby has simple a, low production cost of manufacturing process, wear-resisting, good corrosion resistance, sealing is strong, and characteristics such as long service life.
As shown in Figure 3,, on spheroid 1 outer wall of this ball valve, plate a coating 5, can further increase the surface flatness of spheroid, improve its wear resistance, corrosion resistance and sealing, prolong its working life with spheroid as of the improvement of this model utility ball valve with spheroid.
