1. Indasitiri mamiriro uye marwadzo pfungwa

Muminda yepetrochemical, simba remagetsi, LNG kuchengetedza uye kutakura, dambudziko rekuomerwa mukutenderedza yakakwirira-mavharuvhu epressure (10-42MPa) pamusoro peDN200 iri kuramba ichionekwa. Zvinoenderana nenhamba kubva kuChina Valve Indasitiri Association muna 2024, anopfuura makumi matanhatu nenhatu muzana etsaona dzemaindasitiri ane hukama zvakananga nejamu revharuvhu, iyo yakanyanya-kudzvanywa mamiriro e78%. Dambudziko iri harisi kungowedzera mari yekushanda kwegore negore nekugadzirisa ne 1.2-1.5 bhiriyoni yuan, asiwo inova bhodhoro rinodzivisa kugadzirwa kwakachengeteka.

2. Ongororo yematambudziko ehunyanzvi

2.1 Zvikonzero zvekumanikidza kwevhavha kutenderera kuramba

Data source: Beijing High uye Medium Pressure Valve Research Institute 2024 Test Report

3. Magadzirirwo matsva

3.1 Dhizaini optimization nzira

Structural innovation

Dual disc diversion tekinoroji: kuburikidza nembiri-matanho ekuyamura kumanikidza, imwe-poindi axial simba inoderedzwa ne60% (yakayerwa data)
Bellows sealing system: inobvisa kukweshana uye inoderedza kuvhura nekuvhara torque yeDN250 valve kusvika 35N · m.

Kuvandudza zvinhu

Data source: Kuenzanisa bvunzo yeShanghai Valve Factory muna 2024

3.2 Kushanda uye kugadzirisa manejimendi kusimudzira

Intelligent preload system: chaiyo-kutarisisa nguva yevharuvhu stem stress kuburikidza nemajeji ekusevha, kugadzirisa otomatiki kwe preload simba ( kukanganisa<5%)

Ultrasonic yekuchenesa tekinoroji: kuchenesa vharavhavha makristasi kota yega yega, kuderedza iyo yekunamatira mwero ne82%

Digital twin modhi: kugadzira pressure-torque prediction algorithm ine chokwadi che ±7%

4. Nyaya yedata uye mhedzisiro yekusimbisa

A LNG inogamuchira chiteshi chekugadzirisa chirongwa (2024)

Tekinoroji musanganiswa: Stellite alloy valve musimboti + hydraulic booster mechanism + online yekutarisa system.

5. Maonero enyanzvi uye mafambiro emangwana

Li Ming, director wePressure Vessel Institute yeChina Special Inspection Institute, akataura kuti: “Muna 2025, mavharuvhu akakwira{1}}acharatidza maitiro makuru matatu:

Intelligent actuator: yakabatanidzwa piezoelectric ceramic drive tekinoroji, thrust density yakawedzera ne5 nguva.

Bionic surface engineering: kudzidza kubva kune shark skin structure kugadzira super-hydrophobic valve cavity, kukukurwa kwevhu kwakaderedzwa ne70%

Digital mapatya kushanda uye kugadzirisa: rekodha yakazara hupenyu kutenderera data kuburikidza ne blockchain, kufanotaura kunosvika 95%
