Tehniki aýratynlyklary
Galp polat derwezäniň klapanynyň artykmaçlyklary
1. Ownuk suwuklyga garşylyk.
2. Açmak we ýapmak üçin zerur bolan daşarky güýç az.
3. Gurluşyň akym ugry çäklendirilmeýär.
4. Doly açyk bolanda, möhürleýji ýer, saklaýyş klapanyndan has az işleýär.
5. Bedeniň görnüşi birneme ýönekeý we guýma prosesi has gowudyr.
Galp polat derwezäniň klapanynyň kemçilikleri
1. Daşarky ölçegler we açylyş beýikligi birneme uludyr.Gurmak üçin has uly ýer gerek.
2. Açmak we ýapmak prosesinde möhürlenýän ýüzleriň arasynda otnositel sürtülme bolýar, bu bolsa çyzylmagyna sebäp bolýar.
3. Galp polat derwezeli klapanlarda, adatça, iki sany möhürleýji ýüz bar, bu bolsa gaýtadan işlemekde, üwemekde we bejermekde käbir kynçylyklary döredýär.
