Abstract
The utility model relates to a multifunctional spring seat of a ball valve. The multifunctional spring seat of the ball valve is designed for a hard seal ball valve and a flexible seal ball valve. F304 materials are used as an accessory of a workpiece and a spring is made of incoL750 materials so that the multifunctional spring seat resists abrasion, high temperature and low temperature. The multifunctional spring seat is composed of a lower spring groove, an outer seal ring, a spring and an upper spring groove. When the spring is installed with the upper spring groove and the lower spring groove and the outer seal ring is used for covering the upper spring groove and the lower spring groove. The upper spring groove and the lower spring groove are welded into a whole with argon welding through a welding groove. The spring seat is installed under the a valve seat of the ball valve and two flexible graphite pads are respectively arranged on upper and lower end faces of the spring seat so that the ball valve is reliable in seal. With the spring seat, machining technology of the ball valve is simplified, assembly is simple and service life of the ball valve is prolonged.
Description
Technical field
The utility model relates to a kind of multi-function spring seat of ball valve, and a kind of is the multi-function spring seat of hard seal ball valve and soft sealing ball valve design.
Background technique
The spring of old product ball valve is installed in valve body boring, and exposed as shown in Figure 3, medium usually infiltrates in the valve from spring outside, occurs easily leaking, and can only along direction of arrow pressurization, bear a surface pressure all the time.When stream part medium flow backwards, valve leaked, and spring is subjected to dielectric corrosion, very easily got rusty, and elasticity is weakened, and the sealing of ball valve is more unreliable.
The model utility content
The purpose of this utility model is: a kind of multi-function spring seat of ball valve is provided, as long as this spring seat be installed in ball seat below, just make ball valve have reliable sealing.
The utility model is achieved in that a kind of multi-function spring seat of ball valve, and it is comprised of lower spring groove, outer seal, spring and upper spring groove.Between described lower spring groove and upper spring groove, install spring, with described outer seal lower spring groove and upper spring groove are packaged, be welded into an integral body by bevel for welding with argon welding.
In the utility model, described lower spring groove, outer seal and upper spring groove material are F304; Described spring material is incoL750.
In the utility model, described multi-function spring seat be installed in ball seat below, to respectively add a flexible graphite gasket on two end faces up and down at described multi-function spring seat, when ball seat cooperates with spheroid, spring is transferred to suitable dynamics, when valve seat makes plus-pressure to spring seat, telescopic spring holds out against the flexible gasket at two ends and seals, and makes the sealing surface at two ends, ball valve runner hole can bear equal pressure-Bidirectional pressure.
The beneficial effects of the utility model are, use this spring seat to simplify the processing technology of ball valve, and assembling is simple, and switch is lightly flexible, and sealability is reliable, has prolonged the working life of ball valve.

Fig. 2: a kind of multi-function spring seat installation diagram on ball seat of ball valve;
Fig. 3: old product ball seat spring fitting figure.
Embodiment
Mode of execution below in conjunction with accompanying drawing is described in further detail the utility model: the multi-function spring seat of a kind of ball valve as shown in Figure 1, it is comprised of lower spring groove 1, outer seal 2, spring 3 and upper spring groove 4.Between described lower spring groove 1 and upper spring groove 4, install spring 3, with described outer seal 2 lower spring groove 1 and upper spring groove 4 are packaged, be welded into an integral body by bevel for welding 11 usefulness argon weldings.
Described lower spring groove 1, outer seal 2 and upper spring groove 4 materials are F304; Described spring 3 materials are incoL750.
As shown in Figure 2, described multi-function spring seat be installed in ball seat 5 below, up and down respectively add a flexible graphite gasket 6 on two end faces at described multi-function spring seat, when ball seat 5 cooperates with spheroid 7, spring 3 is transferred to suitable dynamics.When 3 on 5 pairs of springs of valve seat made plus-pressure, spring 3 is flexible to be held out against the flexible graphite gasket 6 at two ends and seals, and makes the sealing surface at two ends, ball valve runner hole can bear equal pressure-Bidirectional pressure.
The multi-function spring seat of a kind of ball valve of the utility model is not limited to the above embodiments, and those skilled in the art make the change of unsubstantiality, all falls into protection domain of the present utility model.
