Problems solved by technology

[0002] In some piping systems where the medium is solid particles or powder (such as coal powder, polysilicon, polypropylene, etc.), due to the characteristics of the working conditions, the performance requirements for the valve are very high, and the valve is required to be wear-resistant, corrosion-resistant, and Due to the characteristics of high temperature and high pressure, long service life, etc., O-type ball valves are generally used in this working condition, but O-type ball valves cannot be used for regulating occasions due to their own flow characteristics. There is no suitable valve product yet

Embodiment Construction

[0019] refer to figure 1 , figure 2 , the solid powder regulating ball valve of the present invention includes a valve body 1, a valve core 8, a valve stem 9, an upper sleeve 11, a lower sleeve 5, a set screw 6, a limit block 10, a rear cover 3, and a valve seat assembly 7 , screw 24, the valve body 1 is an integral structure, the upper part is equipped with an upper bushing 11, the lower part is installed with a lower bushing 5, one side of the valve core 8 is spherical, and the other side is opened with a "V" Type opening, the valve stem 9 is integrated, and fixed with the valve core 8 by the set screw 6, the limit block 10 is located between the valve body 1 and the valve core 8, and the valve core can be made by adding the limit block 10 8 is always concentric with the valve seat 19 to provide sealing and prevent the valve stem 9 from flying out of the valve body 1 under high pressure. The rear cover 3 is located at the tail of the valve body 1 .

Abstract

The invention discloses a solid powder regulation ball valve, which comprises a valve body, a spool, a valve rod, an upper shaft sleeve, a lower shaft sleeve, a set screw, a stop block, a rear cover, a valve seat assembly, screws and the like. Since the solid powder regulation ball valve adopts the one-piece valve rod, the strength and the communication degree are guaranteed; since the partially spherical spool with a V-shaped notch is adopted, the flow characteristic of the valve is changed, as a result, the valve has regulating performance and an automatic shearing function, and the service life of the valve is prolonged; because belleville springs are adopted for pretightening, the sealing specific pressure of a valve seat is guaranteed; dust-proof pads are adopted to prevent powdery medium from entering the spring holes to cause the failure of the springs; the surface of the spool and the sealing surface of the valve seat are specially treated, i.e., nickel-chromium hard alloy is sprayed or surfaced on the surfaces, the abrasive resistance and corrosion resistance of the valve are effectively enhanced, the service life of the valve is prolonged, and the production cost is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of a solid powder state regulating ball valve, and is particularly suitable for the occasions where the solid particle medium or powder state medium needs to regulate the flow of the medium in industrial automatic control. 【Background technique】 [0002] In some piping systems where the medium is solid particles or powder (such as coal powder, polysilicon, polypropylene, etc.), due to the characteristics of the working conditions, the performance requirements for the valve are very high, and the valve is required to be wear-resistant, corrosion-resistant, and Due to the characteristics of high temperature and high pressure, long service life, etc., O-type ball valves are generally used in this working condition, but O-type ball valves cannot be used for regulating occasions due to their own flow characteristics. There are no suitable valve products yet. 【Content of invention】 [0003] The purpose of the...
