I. Overview of A48Y type spring full open safety valve with wrench

      安全阀 适用于工作温度≤350℃的蒸汽、空气等介质的设备和管路上。 A48Y type spring full open safety valve with wrench is suitable for equipment and pipelines with working temperature ≤350 ℃. A44Y spring full-open safety valve with wrench is suitable for equipment or pipelines with working temperature ≤300 ℃ in air, petroleum and other media, as an overpressure protection device. Connection flange standard PN <6.4MPa according to JB / T-94 series 1. PN≥6.4MPa according to JB / T-94 series 2 standard.
 

Second, A48Y type spring full open safety valve structure with wrench

A48Y型带扳手弹簧微启式安全阀 具有结构简单、密封性能好、开启压力准确、排放能力大、回座压差小、调整方便等特点。 1. A48Y spring- opened safety valve with wrench has simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small back seat pressure difference, and easy adjustment.
2. Nozzle-type seat: The valve seat is a Weir nozzle-type seat, the steam reaches the speed of sound when passing through the outlet of the valve seat, the emission coefficient is large, the sealing surface of the valve seat is welded with cobalt chromium tungsten carbide, wear-resistant Eclipse, long life.
3. Thermoelastic valve disc: The valve disc is designed as a thermoelastic structure, which uses its slight deformation under the pressure of the medium to improve the sealing ability, and overcomes the front leakage phenomenon of the safety valve when the pressure is near the set pressure under the pressure of the medium. The sealing surface of the valve disc adopts advanced laser quenching technology, which improves the hardness, wear resistance and impact resistance.
4. Adjusting nut: By adjusting the adjusting nut and adjusting the spring compression, the valve can obtain the accurate setting pressure very conveniently and quickly.
5. Back pressure adjustment sleeve: Auxiliary mechanism for adjusting the back pressure of the valve flap. By adjusting the back pressure adjustment sleeve, a proper back seat pressure difference can be obtained. When adjusting upwards, reduce the valve back pressure. When lowered, increase the valve back pressure.
 

Third, A48Y type spring full open safety valve with wrench installation instructions

1. The safety valve must be installed vertically, and preferably installed directly on the joint of the container or pipeline. The inner diameter of the joint should not be less than the inlet diameter of the safety valve.
2. An appropriate expansion joint must be installed at the outlet of the safety valve to prevent the thermal expansion of the discharge pipe from bringing unwarranted thermal stress to the safety valve. The inner diameter of the discharge pipe should be larger than the diameter of the valve outlet, and the length should be as short as possible to avoid turning. The weight of the discharge pipe and expansion joint shall not act on the safety valve, and shall be fixed on the building. The distance between the centerline of the discharge pipe and the centerline of the valve body is as short as possible. Drain pipes shall be installed separately for each safety valve.
3. There must be sufficient area at the outlet of the muffler to prevent back pressure from affecting the discharge capacity of the valve.
