Primum utrum sit pila valvae velpapilio valvum, Etc., sunt mollis et duris signaculis, accipere pila valvae ut exemplum, usum mollis et dura signacula pila valvulae differt, maxime in structuram et vestibulum signa valvulae repugnat.
Primo, in fabrica mechanism
In durum sigillum pila valvae est metallum, ut-metallum sigillum, et ambo signantes pila et sedes sunt metallum. Et machinens accurate et processum sunt relative difficile, et plerumque in altum pressura, plerumque plus quam 35MPA. Mollis sigillis sunt signacula inter metallis et non-metallis, ut nylon \ PTFE, et vestibulum signa sunt idem.
Secundo, adiungitur materiales
Et mollis et durum sigillum est signing materia de valvae sede, et sigillum durum est praecisione machined cum valvae sedem materiam ad curare ad matching accurate cum valvae core (pila), plerumque immaculatam ferro et aeris. Mollis signatio significat quod signantes materia embedded in valvae sede est a non-metallicis materia, quia mollis signing materia est quaedam elasticitate, ita ad pressing accuratam requiruntur erit inferior, ita ad pressing accuracy erit inferior, ut ad pressing accuracy erit inferior, ita ad pressing accuratam et inferior, quam ad pressing accuracy erit inferior, quam ad pressing accuracy erit inferior, quam ad pressing accuracy erit inferior, quam ad pressing accuracy erit inferior, ita ad pressing.
Tertio, in vestibulum processus
Due to a lot of chemical industry, the working environment of the machinery industry is more complex, many are high temperature and high pressure, the friction resistance of the medium is large, and the corrosion is strong, now the technology has progressed, the use of various materials is better, and the processing and other aspects can keep up, so that the ball valve with hard seal has been widely promoted.
In facto, principium durum sigillum pila valvae idem est quod molli sigillum, sed quia est sigillum inter metallis, necesse est ut in ob duritiam necessitudinem inter metalla, tum opus est ad consequi, et sedes, semper ad consequi sigillum et sedes constantly ad consequi et sigillum et sedem constantly ad consequi sigillum et sedes constanter ad consequi sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi sigillum et sedes constantius ad consequi sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi et sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi sigillum et sedes constantius ad consequi sigillum et sedes constantius ad consequi sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi et sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi et sigillum et sedes constantly ad consequi sigillum et sedes constantly ad consequi sigillum. Productio cycle durum sigilli pila valvae longa, processus est magis complicated, et non facile est facere bonum officium duro sigilli pila valvae.
Quartum, in conditionibus usus
Sigillis mollis potest plerumque pervenire sigillis dum dura signacula potest esse altum vel humilis secundum requisita; Mollis sigillis postulo ut fireproof, quia ad altum temperaturis, in materia mollis sigillum erit Leak, dum durum sigillum non habet hoc problema; Ferreus signaculis plerumque cum magno pressuris, mollis sigillis non potest; Ob quaestionem de medium fluens, mollis sigillum non possunt in aliqua occasiones (ut quidam mordendo media); Ultima durum sigillum valvae plerumque magis pretiosa quam mollis sigillum valvae. Ut enim vestibulum, non est multo differentia inter duo, pelagus res est differentia inter valvae sedes, mollis sigillum est non-metallicum et durum sigillum sit metallum.
Quintus in lectio apparatu
The selection of soft and hard seal ball valves is mainly based on the process medium, temperature and pressure, the general medium contains solid particles or has wear or the temperature is higher than 200 degrees, it is good to choose hard seals, the diameter is greater than 50, the valve pressure difference is larger, and the torque of the opening valve is also considered, and the fixed hard seal ball valve should be selected when the torque is larger, regardless of the soft and hard seals, the Signans gradu potest pervenire campester VI.
