Saat memasangkatupUntuk mencegah masuknya logam, pasir, dan benda asing lainnya ke dalam katup dan merusak permukaan penyegelan, perlu dipasang filter dan katup pembilas; Untuk menjaga kebersihan udara terkompresi, pemisah minyak-air atau filter udara harus dipasang di depan katup; Mengingat kondisi kerja katup dapat diperiksa selama pengoperasian, perlu dipasang instrumen dan katup uji; Untuk menjaga suhu pengoperasian, fasilitas isolasi termal dipasang di luar katup; Untuk memasang katup, perlu dipasang katup pengaman dan katup periksa; Mengingat pengoperasian katup yang berkelanjutan, sistem paralel atau sistem bypass harus dipasang.
Langkah-langkah perlindungan darikatup periksa
Untuk mencegah kebocoran katup searah atau aliran balik media setelah kerusakan, yang mengakibatkan penurunan kualitas produk dan kecelakaan, satu atau dua katup penutup harus dipasang sebelum dan sesudah katup searah. Jika dua katup penutup dipasang, katup searah dapat dengan mudah dibongkar dan diperbaiki.
Langkah-langkah perlindungan darikatup pengaman
Terdapat tiga jenis fasilitas pemasangan katup pengurang tekanan. Pengukur tekanan dipasang di bagian depan dan belakang katup pengurang tekanan untuk mengamati tekanan sebelum dan sesudah katup. Terdapat juga katup pengaman tertutup sepenuhnya di belakang katup, untuk menghindari terjadinya trip ketika tekanan di belakang katup melebihi tekanan normal setelah kegagalan katup pengurang tekanan, termasuk sistem di belakang katup.

When installing the valve. To prevent metal, sand and other foreign objects from entering the valve and damaging the sealing surface, it is necessary to install a filter and flushing valve; To keep the compressed air clean, an oil-water separator or air filter must be installed in front of the valve; Considering that the working condition of the valve can be checked during operation, it is necessary to install test instruments and valves; To maintain operating temperature, thermal insulation facilities are installed outside the valve; To install the valve, it is necessary to install a safety valve and a check valve; Considering the continuous operation of the valve, a parallel system or bypass system must be installed.
Protective measures of check valves
To prevent non-return valve leakage or medium backflow after damage, resulting in product quality degradation and accidents, one or two shut-off valves should be installed before and after the non-return valve. If two shut-off valves are installed, the check valve can be easily disassembled and repaired.
Protective measures of safety valves
There are three types of pressure reducing valve installation facilities. Pressure gauges are installed at the front and back of the pressure reducing valve to observe the pressure before and after the valve. There is also a fully closed safety valve behind the valve, to avoid tripping when the pressure behind the valve exceeds the normal pressure after failure of the pressure reducing valve, including the system behind the valve.
