Problems solved by technology

Since the spray hardening treatment process is carried out after the valve ball is finished, the heat emitted during the process will inevitably lead to deformation of the spherical surface, and due to the structural characteristics of the eccentric ball, there are often obvious shape and position deviations when it is clamped and ground again after spraying, resulting in When the valve is closed, the spherical surface and the valve seat are difficult to fit tightly, which affects the cutting performance of the valve

Embodiment Construction

[0023] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0024] Such as Figure 1~7 As shown, the present invention mainly includes an erosion-resistant spherical surface 1, an expansion ring 2, a locking block 3, and an eccentric ball handle 4. A positioning hole 4a is provided on one side of the eccentric ball handle 4, and the locking block is connected with a screw 5 in the positioning hole 4a. 3.

[0025] The inner front end surface of the positioning hole 4 a is the positioning surface of the locking block 3 , and the inner rear end surface of the positioning hole 4 a is the positioning surface of the screw 5 .

[0026] Such as Figure 7 As shown, the side of the eccentric ball handle 4 facing away from the positioning hole 4a is provided with a counterbore 4b. When the screw 5 is installed, it first passes through the counterbore 4b and then enters the positioning hole 4a.

[0027] Such as Figure...

Abstract

The invention relates to a valve ball locking structure, in particular to a valve ball conical surface locking structure of a flushing-resistant eccentric ball valve and belongs to the technical field of fluid control valves. The valve ball conical surface locking structure comprises a flushing-resistant ball surface, a distensible ring, a locking block and an eccentric ball handle, wherein a positioning hole is formed in one side of the eccentric ball handle; the interior of the positioning hole is connected with the locking block through a screw; the outer surface of the front end of the locking block is a locking outer conical surface; the distensible ring is arranged on the external circumference of the front end of the locking block; the inner surface of the distensible ring is a locking inner conical surface; the locking outer conical surface of the locking block is glidingly matched with the locking inner conical surface of the distensible ring; the locking block drives the distensible ring to tightly stick to the surface of the front end of the eccentric ball handle. The flushing resistance of the valve ball is improved, finally the service life of the valve is prolonged, and the safe, stable and effective operation of a gasification device in the coal chemical industry is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a valve ball locking structure, in particular to a valve ball cone surface locking structure of an eccentric ball valve with erosion resistance, and belongs to the technical field of fluid control valves. Background technique [0002] With the increasing shortage of petroleum resources and considering the actual situation of my country's resource reserves, the coal chemical industry, which uses coal instead of petroleum to produce various chemical products, has been paid more and more attention. The overall strategy of my country's energy development has gradually changed to: "Insist on conservation , based on domestic, coal-based, diversified development, optimize the production and consumption structure, and build a stable, economical, clean and safe energy supply system", which means that the coal chemical industry is facing an unprecedented good opportunity. [0003] The route of producing synthesis gas by coal gasification ...
