Description

Technical Field

[0001] The utility model relates to the technical field of Texaco water-coal slurry gasification process, in particular to an angle valve buffer device. Background Art

[0002] The liquid level of the carbon washing tower in the Texaco water-coal slurry gasification process is adjusted by the liquid level regulating valve and then discharged into the high-pressure flash tank for subsequent treatment. The regulating valve is an angle valve structure with a large pressure difference between the front and rear. During operation, there is a three-phase flow of gas, liquid and solid. After entering the buffer device, the medium first reaches the bottom along the straight pipe section, hits the flange cover and returns upward, and flows out from the horizontal pipe section at the tee. The medium changes direction greatly inside the buffer device, which causes erosion and wear on the buffer pipeline after the valve, especially at the tee position, where leakage often occurs, posing certain safety risks.

[0003] However, the prior art still has the following problems:

[0004] First of all, in the existing production practice, in order to resist scouring, scour-resistant materials are usually used or the wall thickness is increased to make the angle valve have a buffering effect when in use to achieve the purpose of reducing leakage. However, this not only increases the production cost but also often has unsatisfactory effects. The existing angle valve is mainly composed of a straight pipe section, a tee, a horizontal pipe section and a concentric reducer. After entering the buffer device, the medium first reaches the bottom along the straight pipe section, hits the flange cover and returns upward, and flows out from the horizontal pipe section at the tee. The direction of the medium changes greatly inside the buffer device, and a leakage area is prone to occur.

[0005] Secondly, the existing angle valve structure does not have a good connecting component. In order to better use the angle valve, it is necessary to tightly connect the flange cover and the flange on the straight pipe body to avoid leakage of the medium used by the angle valve. The lack of a connecting component makes it inconvenient to firmly connect the flange and the flange cover, reducing the practicality of the angle valve structure.

[0006] In view of the above problems, the inventor proposes an angle valve buffer device to solve the above problems. Utility Model Content

A groove is opened at the top of the flange cover, and a plurality of springs are fixedly connected to the lower inner wall of the groove. The plurality of springs are distributed in a ring array, and the springs serve as a rebound. A circular plate used in conjunction with a long radius elbow pipe is jointly fixedly connected to the tops of the plurality of springs, so that the medium falls onto the circular plate and cooperates with the spring to make the circular plate return the medium upward.

[0023] By adopting the above technical solution, the flow direction of the medium is facilitated and the leakage of the medium is reduced.

[0027] By adopting the above technical solution, it is convenient to use the circular plate 21 in conjunction with the flange cover 5 .

[0028] Embodiment 2: Figure 4-5As shown, the connecting assembly 4 includes connecting bolts 48, and there are ten connecting bolts 48.
