Yintoni i-valve yoxinzelelo oluphantsi, uluhlu loxinzelelo kunye nokuhlelwa komgangatho we-valve ephantsi

I-valve licandelo lolawulo kwinkqubo yokuhanjiswa kwamanzi. Yimveliso yomatshini elawula ukuhamba kwamanzi, uxinzelelo kunye nolwalathiso lokuhamba ngokutshintsha ubungakanani bendawo yokuhamba kwayo. Kukho iintlobo ezininzi zeevalvu, kwaye ivalve yoxinzelelo oluphantsi luhlobo olusetyenziswa rhoqo. Yintoni uxinzelelo lwevalve yoxinzelelo oluphantsi? Lo mbandela uzisa uluhlu loxinzelelo kunye nokuhlelwa komgangatho weevalvu eziphantsi koxinzelelo! Ndiyathemba ukukunceda!

1¡¢ Yintoni uxinzelelo lwevalve yoxinzelelo oluphantsi

Ngokubanzi, iindawo zokwahlula ziyi-1.6Mpa kunye ne-10.0MPa. Umbhobho woxinzelelo oluphantsi ngulo onoxinzelelo loyilo olungaphantsi okanye olulingana ne-1.6Mpa, umbhobho woxinzelelo oluphakathi ngulo onoxinzelelo loyilo olukhulu kuno-1.6Mpa kwaye lungaphantsi okanye lulingana no-10.0MPa, kunye nombhobho woxinzelelo oluphezulu. yeyona inoxinzelelo loyilo olukhulu kuno okanye olulingana no 10.0MPa. Umbhobho woxinzelelo ubhekisela kuyo yonke imibhobho ephethe uxinzelelo lwangaphakathi okanye lwangaphandle, kungakhathaliseki ukuba yintoni na iphakathi kumbhobho.

Olunye uxinzelelo lwevalvu lunokwahlulwa ngoku

1. Uxinzelelo lobunjineli bombhobho woxinzelelo oluphantsi

2. Uxinzelelo lwemibhobho yoxinzelelo oluphakathi lusebenza ngu-1.6-6.4mpa

3. Uxinzelelo oluphezulu lobunjineli bombhobho> 10MPa

Ivalve yoxinzelelo oluphezulu ———– uxinzelelo lwegama PN ¡Ý 100MPa;

Ivalve yoxinzelelo oluphezulu ———– uxinzelelo lwegama PN10 0 ~ 80.0MPa;

Ivalve yeMP ———– uxinzelelo lwegama pN2 5 ~ 6.4MPa;

Ivalve yoxinzelelo oluphantsi ———– uxinzelelo lwegama PN ¡Ü 1.5MPa

2¡¢ Uluhlu loxinzelelo kunye nokuhlelwa kwebakala le-valve yoxinzelelo oluphantsi

1. Ivalve yevacuum: ivalve enoxinzelelo

2. Ivalve yoxinzelelo oluphantsi: ivalve enoxinzelelo lwegama PN ¡Ü 1.6Mpa (kubandakanywa ivelufa yentsimbi ene-PN ¡Ü 1.6Mpa)

3. Ivalve yoxinzelelo oluphakathi: uxinzelelo lwegama pN2 5-6.4mpa valve.

4. Ivalve yoxinzelelo oluphezulu: uxinzelelo lwegama PN10 0-80.0mpa valve.

5. Ivalve ephezulu yoxinzelelo oluphezulu: ivalve ene-PN yoxinzelelo lwegama ¡Ý 100.0mpa.
