Problems solved by technology

[0002] The working conditions of the coal gasification process are harsh. The slag-water mixture flowing through the valve has complex components, high concentration of chloride ions, and a large number of solid particles; The slag will invade the inside of the valve seat assembly, causing the valve seat to fail, causing the valve to leak or even become unusable

Embodiment Construction

[0013] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Such as figure 2 As shown, the embodiment of the present invention provides a double-isolated particle metal-sealed ball valve, including a ball 1, a valve seat 2, a sealing ring 3, a first backing ring 4, a leaf spring 5, a second backing ring 6, a graphite gasket 7 and a valve body 8. The valve seat 2 is provided with a ball 1, and the valve seat 2 and the valve body 8 are matched by the sealing ring 3, the first backing ring 4, the leaf spring 5, the second backing ring 6, and the graphite pad 7 in sequence.

[0015] It should be noted that the sphere 1 mentioned above is a wear-resistant metal sphere.

[0016] It should be noted th...

Abstract

The invention discloses a double isolation particle metal sealing ball valve which comprises a ball body, a valve seat, a sealing ring, a first backing ring, a plate spring, a second backing ring, a graphite mat and a valve body. The ball body is arranged on the valve seat, and the valve seat and the valve body are matched through the sealing ring, the first backing ring, the plate spring, the second backing ring and the graphite mat sequentially. The double isolation particle metal sealing ball valve is reasonable in structural design, convenient and reliable to operate and long in service life, and has the scale formation preventing scraping blowing function.

Description

technical field [0001] The invention relates to the technical field of hardware valves, in particular to a metal-sealed ball valve with double isolation particles. Background technique [0002] The working conditions of the coal gasification process are harsh. The slag-water mixture flowing through the valve has complex components, high concentration of chloride ions, and a large number of solid particles; The slag will invade the inside of the valve seat assembly, causing the valve seat to fail, causing the valve to leak or even become unusable. [0003] According to harsh working conditions, for existing wear-resistant ball valves (such as figure 1 Shown) technology and valve sealing principle, the present invention has designed a kind of metal sealing ball valve of double isolation particle, improves valve sealing performance. Contents of the invention [0004] In order to solve the above problems, the present invention provides a metal-sealed ball valve with double i...
