Problems solved by technology

[0003] The two-piece ceramic ball valve is used for fluid regulation and control in pipeline transportation, and as the structural characteristics and advantages of the two-piece ceramic ball valve, the valve only needs to rotate 90 0 The rapid opening and closing action of the valve body can be completed. This structural feature and advantage not only improves the opening and closing efficiency of the valve, but also increases the water hammer effect caused by the sudden closing of the valve when the transport medium is liquid. The harmful impact of the harmful impact, especially the transportation of large-diameter and long pipelines, this disadvantage will be more obvious, greatly reducing the service life and stability of the pipeline, increasing the cost of pipeline monitoring, and burying possible safety hazards for industrial production

specific Embodiment approach

[0026] As a specific embodiment of the present invention, the bottom of the installation groove 241 is provided with a No. 2 sealing port 242; the No. 2 bracket 24 is provided with a restraint device 4 corresponding to the installation groove 241; the restraint device 4 includes a T-shaped bar 41 and helical gear; the T-end of the T-shaped rod 41 is inserted in the spring 3; the other end of the T-shaped rod 41 passes through the second sealing port 242 and is fixedly connected to the No. 1 bevel gear 42; the No. 1 cone The gear 42 meshes with the No. 2 bevel gear 3; the inner surface of the No. 2 bevel gear 3 is fixedly connected to the transmission rod 44; the transmission rod 44 runs through the No. 2 cavity 243 inside the No. The knob 5 on the surface is fixedly connected;

[0027] After the outer net 21 leaving the surface of No. 2 bracket 24 finishes absorbing the impact force brought by the liquid water hammer effect, the knob 5 on the upper surface of No. 2 bracket 24 ...

Embodiment approach

[0034] As a specific embodiment of the present invention, a sealing sleeve 6 is provided at the joint between the No. 1 cavity 112 inside the left valve body 11 and the buffer device 2; a sealing gasket is provided at the fixed connection between the transmission rod 44 and the knob 5 7;

[0035] The setting of the sealing sleeve 6 and the sealing gasket 7 can ensure that the buffer device 2 prevents medium leakage when inserted into the pipeline of the left valve body 11, and ensures that the ball valve will not affect the normal use of the ball valve due to insufficient sealing performance.

[0036] Working principle: A buffer device 2 composed of a double-layer net is inserted in the ball valve pipeline. The net structure can not only disperse the pressure of the liquid impact, but also block and filter some impurities during the normal operation of the ball valve. The design of the double-layer net not only The structural strength of the buffer device 2 can be improved, an...

Abstract

The invention belongs to the field of pipeline transportation, and particularly relates to a two-piece type ceramic ball valve, which is characterized in that a pluggable buffer device is arranged in an inlet pipeline of a valve body, and a buffer device main body consists of an inner net and an outer net, so that the impact of a water hammer effect on the pipeline and the valve body can be buffered at the moment when the ceramic ball valve is closed; in addition, the ceramic ball valve can play a role in blocking and filtering impurities in normal liquid medium transportation, and excessive impurities are prevented from being accumulated in the ball valve, so that the safety and the stability of the ceramic ball valve in use are improved.

Description

technical field [0001] The invention belongs to the field of pipeline transportation, in particular to a two-piece ceramic ball valve. Background technique [0002] In the past ten years, due to the development and progress of martensitic transformation toughening technology, composite material technology and the concept of nano-ceramic, the "brittleness" of ceramics has been greatly improved, and its toughness and strength have been greatly improved. , the scope of application continues to expand. Ceramic ball valves are an important attempt of ceramics in the field of pipeline transportation. All parts in contact with the medium in ceramic ball valves are made of structural ceramic materials, and their chemical stability and hardness are extremely high, second only to diamond. Therefore, ceramic ball valves have extremely high wear resistance, corrosion resistance, erosion resistance, good heat insulation, and small thermal expansion, so they are widely used in petroleum ...
