Problems solved by technology

[0003] To sum up, there are the following problems in the spring box of the oil-motor control seat in active service: 1. The spring positioning error of the spring box of the oil-motor control seat is large; The rod is rubbed or stuck; 3. In the compressed state, the spring and the guide rod are fretting for a long time, resulting in hardening, fracture or serious wear of the spring surface; 4. The spring box of the oil motor control seat has a single structure and lacks corresponding anti-collision measures. Affect the normal use of the control seat

Abstract

The invention relates to a hydraulic servo-motor control seat spring box. The spring box comprises a box body, a guide rod (4), a guide sleeve, a spring and a connector rod (15) are arranged in the box body, the guide rod (4) is connected with the box body, one end of the guide sleeve is connected with the box body, the other end of the guide sleeve is connected with the connector rod (15) in a sliding mode, the guide sleeve and the connector rod (15) are sleeved with the spring, a wear-resistant copper sleeve is installed at the end, close to the guide rod (4), of the guide sleeve and connected with the guide rod (4) in a mechanical contact mode. The hydraulic servo-motor control seat spring box has the advantages of vibration prevention, vibration resistance, impact and abrasion resistance, collision and abrasion prevention, long service life and the like. Under the conditions of large torque, long stroke and horizontal installation, the vibration amplitude and impact abrasion of equipment can be effectively reduced, the abrasion failure of the spring is avoided, the reliability of the hydraulic servo-motor control seat spring box is greatly improved, and the safe and stable operation of a unit is effectively ensured.

Description

Technical field[0001]The invention relates to the technical field of an oil motor operating seat spring box, in particular to an oil motor operating seat spring box.Background technique[0002]During the normal operation of the nuclear power plant unit, the oil pressure of the regulating oil system overcomes the spring force of the control seat spring of the steam turbine reheat steam valve to ensure the opening of the steam valve. When the nuclear power plant unit is shut down or abnormal transient conditions, the regulating oil system releases the pressure and the steam turbine reheat steam valve is in The oil motor operating seat is closed under the elastic force of the spring. Due to the large closing torque of the reheat valve of the steam turbine, the long stroke and the limitation of the installation environment, the length of the spring box of the oil motor operating seat reaches nearly 2m. Although the spring in the spring box of the hydraulic motor control seat is provided w...
