進(jìn)口衛(wèi)生級(jí)減壓閥(德國奧萊斯閥門品牌)
【進(jìn)口衛(wèi)生級(jí)減壓閥】產(chǎn)品介紹:
衛(wèi)生級(jí)減壓閥是通過調(diào)節(jié),將進(jìn)口壓力減至某一需要的出口壓力,并依靠介質(zhì)本身的能量,使出口壓力自動(dòng)保持穩(wěn)定的閥門。即通過改變節(jié)流面積,使流速及流體的動(dòng)能改變,造成不同的壓力損失,從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié),使閥后壓力的波動(dòng)與彈簧力相平衡,使閥后壓力在一定的誤差范圍內(nèi)保持恒定。衛(wèi)生級(jí)減壓閥是一種自動(dòng)降低管路工作壓力的專門裝置,它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。減壓閥的構(gòu)造類型很多,按結(jié)構(gòu)形式可分為薄膜式、彈簧薄膜式、活塞式、杠桿式和波紋管式等。衛(wèi)生級(jí)減壓閥壓力特性是指流量g為定值時(shí),因輸入壓力波動(dòng)而引起輸出壓力波動(dòng)的特性。輸出壓力波動(dòng)越小,減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。流通過衛(wèi)生級(jí)減壓閥雖有很大的水頭損失,但由于減少了水的浪費(fèi)并使系統(tǒng)流量分布合理、改善了系統(tǒng)布局與工況,因此總體上講仍是節(jié)能的。介質(zhì)為蒸汽的場(chǎng)合,宜選用先導(dǎo)活塞式減壓閥或先導(dǎo)波紋管式減壓閥。
Hygienic pressure relief valve is a kind of valve that can automatically keep the outlet pressure stable by adjusting the inlet pressure to a certain outlet pressure and relying on the energy of the medium itself. That is to say, by changing the throttle area, the flow velocity and the kinetic energy of the fluid can be changed, resulting in different pressure losses, so as to achieve the purpose of decompression. Then, the fluctuation of the back pressure of the valve is balanced with the spring force by the adjustment of the control and regulation system, so that the back pressure of the valve remains constant within a certain error range. Hygienic pressure relief valve is a special device which can automatically reduce the working pressure of pipeline. It can reduce the high liquid pressure in front of the valve to the required level in back pipeline.
