Abstract
The invention relates to a multifunctional spring base, and in particular relates to a multifunctional spring base for a ball valve, which is designed for a rigid seal ball valve or a soft seal ball valve. In order to ensure that the multifunctional spring base has the performance of resisting corrosion, high temperature and low temperature, an F304 material is used to make the parts of a workpiece, and an incoL750 material is used to make a spring. The multifunctional spring base is composed of a lower spring slot, an outer seal ring, the spring and an upper spring slot; and when the spring is arranged in the upper spring slot and the lower spring slot, the upper spring slot and the lower spring slot are sleeved through the outer seal ring, and welded integrally through a weld groove by argon welding. The spring base is arranged under the valve seat of the ball valve, and a flexible graphite spacer is additionally arranged at the upper end face and lower end face of the spring base respectively, so that the ball valve is sealed reliably; and with the spring base, the machining process of the ball valve is simplified, the ball valve is easy to assemble, and simple and flexible to open and close, the sealing property of the ball valve is reliable, and the service life of the ball valve is prolonged.
Description
Technical field
The present invention relates to a kind of multi-function spring seat of ball valve, a kind of is the multi-function spring seat of hard seal ball valve and soft sealing ball valve design.
Background technique
The installation of on valve body, holing of the spring of old product ball valve, exposed outside, as shown in Figure 3, medium is normal
Infiltrate in the valve from spring, occur easily leaking, and can only bear one side and press along direction of arrow pressurization all the time
Power.When stream part medium flow backwards, valve leaked, and spring receives dielectric corrosion, very easily got rusty, and made bullet
Property weakens, and the sealing of ball valve is more unreliable.
Summary of the invention
The objective of the invention is to: a kind of multi-function spring seat is provided, as long as this spring seat be installed in ball seat below, just make ball valve have reliable tightness.
The present invention is achieved in that a kind of multi-function spring seat of ball valve, and it is made up of lower spring groove, outer seal, spring and upper spring groove.Between said lower spring groove and upper spring groove, install spring, lower spring groove and upper spring groove are overlapped, be welded into an integral body with argon welding through bevel for welding with said outer seal.
Among the present invention, said lower spring groove, outer seal and upper spring groove material are F304; Said spring material is incoL750.
Among the present invention; Said 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 said multi-function spring seat, when ball seat cooperates with spheroid, be transferred to suitable dynamics to spring, 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-two-way pressure.
The invention has the beneficial effects as follows, use this spring seat to simplify the processing technology of ball valve, assembling is simple, and switch is lightly flexible, and sealability is reliable, has prolonged the working life of ball valve.
Description of drawings
Fig. 1: a kind of multi-function spring seat ssembly drawing 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 installation diagram.
Embodiment
Mode of execution below in conjunction with accompanying drawing is done further explain to the present invention: the multi-function spring seat of a kind of ball valve as shown in Figure 1, it is made up of lower spring groove 1, outer seal 2, spring 3 and upper spring groove 4.Between said lower spring groove 1 and upper spring groove 4, install spring 3, lower spring groove 1 and upper spring groove 4 are overlapped, be welded into an integral body through bevel for welding 11 usefulness argon weldings with said outer seal 2.
Said lower spring groove 1, outer seal 2 and upper spring groove 4 materials are F304; Said spring 3 materials are incoL750.
As shown in Figure 2, said 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 said multi-function spring seat, when ball seat 5 cooperates with spheroid 7, be transferred to suitable dynamics to spring 3.When 3 on 5 pairs of springs of valve seat made plus-pressure, spring 3 is flexible to hold 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-two-way pressure.
The multi-function spring seat of a kind of ball valve of the present invention is not limited to the above embodiments, and those skilled in the art make the change of unsubstantiality, all falls into protection scope of the present invention.
