Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific examples.

[0026] As shown in the figure, the high-pressure hydrogenation reaction special material regulating angle valve includes a valve body 1, a valve seat 2, a valve stem 3 and a valve core 4. The valve seat 2 is fixed on the valve body 1 and slides in the valve body 1. The valve stem 3 is plugged tightly, and the valve core 4 is integrally connected to the bottom end of the valve stem 3. An auxiliary guide seat 5 is installed between the valve body 1 and the valve seat 2, and the auxiliary guide seat 5 An anti-scour sleeve 6 is installed on the top, one end of the anti-scour sleeve 6 is embedded in the auxiliary guide seat 5, the other end of the anti-scour sleeve 6 is embedded in the valve body 1, and the valve stem 3 is slidably inserted into the anti-scour sleeve. Inside tube 6.

[0027] There are two flushing ports 7 on the outside of the valve body, one flushing port 7 is se...

Abstract

The invention relates to a special material regulating angle valve for a high-pressure hydrogenation reaction. A valve seat is fixed on a valve body, a valve rod is spliced in the valve body in a sealing and sliding manner, a valve core is in integrated connection with the bottom end part of the valve rod, an auxiliary guide seat is mounted between the valve body and the valve seat, an anti-erosion sleeve is mounted on the auxiliary guide seat, one end of the anti-erosion sleeve is embedded into the auxiliary guide seat, the other end of the anti-erosion sleeve is embedded into the valve body, and the valve rod is spliced in the anti-erosion sleeve in a sliding manner. With the adoption of the special material regulating angle valve, the accumulation of a medium on an inner wall is prevented, the erosion of the high speed medium to internal pieces of the valve is reduced, the valve rod is not blocked by the granular medium, the service life of the valve rod is prolonged, and the stability and reliability of the auxiliary guide seat are ensured.

Description

technical field [0001] The invention relates to a regulating angle valve, in particular to a regulating angle valve made of special material for high-pressure hydrogenation reaction. Background technique [0002] The hydrogenation reactor is the main part of the refining unit of the PTA plant. In the reactor, the TA slurry and hydrogen undergo a chemical reaction at a temperature of 315°C and a pressure of 8.5MPa to further generate PT acid from the intermediate product 4-CBA. After the reaction The high-temperature, high-pressure process slurry enters the next process through the adjusting angle valve. [0003] We know that when the liquid medium with pressure P1 flows through the orifice of the regulating valve, the flow rate increases and the static pressure decreases. When the pressure P2 behind the orifice of the regulating valve is equal to or less than the saturation of the liquid medium under the working condition When the vapor pressure is Pv, part of the liquid me...
