AI Technical Summary

Technical Problem

Existing desuperheating and pressure reducing devices often result in steam pressure exceeding the specified value during use, leading to resource waste. Furthermore, they require high precision machining, have high maintenance costs, are prone to spring damage, cannot flexibly adjust the pressure reduction effect, and have poor adaptability.

Method used

Employing a multi-hole valve core structure, the medium pressure is precisely adjusted by controlling the rotation angle and speed of the drive component. Combined with a spiral cooling water delivery system and noise reduction components, precise regulation and cooling are achieved, reducing energy loss and equipment wear.

Benefits of technology

It improves the applicability and versatility of pressure reducers, reduces production and maintenance costs, enhances the automation level and operational reliability of equipment, and reduces energy loss and noise pollution.

Abstract

The temperature and pressure reducer comprises a valve body and a conveying pipeline which are arranged, the side end of the valve body is connected with the conveying pipeline, a maintenance part is arranged at the bottom of the valve body, a driving part is installed in the valve body, the lower portion of the driving part is connected with the valve element, the valve element is located in the valve body, and the valve element is arranged in the valve body. Two pairs of through holes are symmetrically formed in the valve element, the diameters of the two pairs of through holes are different, and a pressure gauge is installed on the valve body. According to the temperature and pressure reducer with the porous valve element, the pressure of a medium is accurately adjusted by controlling the rotating angle and speed of the driving piece, the pressure requirements under different working conditions are met, meanwhile, energy loss and equipment abrasion possibly caused by a traditional pressure reduction mode are reduced, two pairs of through holes with different diameters are symmetrically formed in the valve element, and the pressure reduction effect is good. The pressure reduction adjusting range and precision are enhanced, the device can adapt to changes of pressure of various media, the applicability and universality of the device are improved, and the problem that production and maintenance cost is increased due to the fact that an auxiliary structure is used is solved.
