Embodiment Construction
[0014] Below in conjunction with the embodiment of accompanying drawing, the present invention will be described in further detail: as figure 1 The multifunctional spring seat of a ball valve shown is composed of a lower spring groove 1, an outer sealing ring 2, a spring 3 and an upper spring groove 4. Install the spring 3 between the lower spring groove 1 and the upper spring groove 4, use the outer sealing ring 2 to cover the lower spring groove 1 and the upper spring groove 4, and weld the groove 11 with argon welding to form a overall.
[0015] The material of the lower spring groove 1, the outer sealing ring 2 and the upper spring groove 4 is F304; the material of the spring 3 is incoL750.
[0016] like figure 2 As shown, the multifunctional spring seat is installed under the ball valve seat 5, and a flexible graphite gasket 6 is added to the upper and lower end faces of the multifunctional spring seat, and the ball valve seat 5 is matched with the ball 7. Ad...

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 [0001] The invention relates to a multifunctional spring seat for a ball valve, in particular to a multifunctional spring seat designed for hard-sealed ball valves and soft-sealed ball valves. Background technique [0002] The spring of the old product ball valve is drilled and installed on the valve body, and is exposed outside, such as image 3 As shown, the medium is often [0003] It seeps into the valve from the spring, and it is prone to leakage, and it can only be pressurized in the direction of the arrow at all times, and it can withstand one side of the pressure. [0004] force. When the flow medium flows backwards, the valve will leak, and the spring is corroded by the medium, which is easy to rust, making the spring [0005] The performance is weakened, and the sealing performance of the ball valve is more unreliable. Contents of the invention [0006] The object of the present invention is to provide a multifunctional spring seat, as...
