消防器材是指用于滅火、防火以及火災(zāi)事故的器材。用于專業(yè)滅火的器材。最常見(jiàn)的消防器材：滅火器，它按驅(qū)動(dòng)滅火器的壓力型式可分為三類：1.貯氣式滅火器。滅火劑由滅火器上的貯氣瓶釋放的壓縮氣體的或液化氣體的壓力驅(qū)動(dòng)的滅火器。 2.貯壓式滅火器。滅火劑由滅火器同一容器內(nèi)的壓縮氣體或滅火蒸氣的壓力驅(qū)動(dòng)的滅火器。3.化學(xué)反應(yīng)式滅火器。滅火劑由滅火器內(nèi)化學(xué)反應(yīng)產(chǎn)生的氣體壓力驅(qū)動(dòng)的滅火器。安徽金建建材有限公司從事消防器材銷售，質(zhì)量?jī)?yōu)，價(jià)格合理，歡迎各界人士進(jìn)行咨詢選購(gòu)!

一．止回閥防水錘的疑問(wèn)tKJ)'v?正如我們專業(yè)課本中所學(xué)到的，止回閥實(shí)際上是造成水錘的根本原因。如果我們?cè)O(shè)想水泵是可以倒轉(zhuǎn)的，而且不會(huì)破壞，那么在突然停泵之后，返回的壓力波會(huì)通過(guò)水泵流至吸水池當(dāng)中，能量被安全釋放，因此并不會(huì)產(chǎn)生水錘。水流速度的突然變化，即是產(chǎn)生水錘的根本原因。只要水的流速發(fā)生變化，系統(tǒng)壓力必然發(fā)生變化。正是由于止回閥的阻擋作用使得我們會(huì)出現(xiàn)典型的“停泵水錘”，止回閥的關(guān)閉使得水流的速度發(fā)生***變化，因此會(huì)產(chǎn)生危險(xiǎn)的壓力波動(dòng)。盡管長(zhǎng)時(shí)期以來(lái)，尤其是國(guó)內(nèi)的實(shí)踐應(yīng)用，通過(guò)緩閉或者兩階段關(guān)閉等等方式消除水錘得到過(guò)認(rèn)可，但是其適用性還是值得探討。9(B)首先，從非專業(yè)理論的層面上看，通過(guò)調(diào)整造成水錘的因素來(lái)解決水錘，同時(shí)又不作根本的變動(dòng)，本身就是一種冒險(xiǎn)的形為。每個(gè)事物都有好與壞的兩方面，人類并不能將壞的方面全部轉(zhuǎn)化成有利的方面，否則就破壞了宏觀的基礎(chǔ)理論，成為正確哲學(xué)的悖論。接下來(lái)，并不是緩閉的或者兩階段關(guān)閉的止回閥是“應(yīng)用四海皆準(zhǔn)”的普適定律；因?yàn)?，水錘是針對(duì)全系統(tǒng)而言，并不特指水泵站。因此，止回閥常常不是解決水錘的***答案，工程人員必須進(jìn)行全系統(tǒng)的通盤考慮，綜合解決。在不限制閘閥整體自由變形的情況下，與流體壓力相比，因熱產(chǎn)生的變形較大，而應(yīng)力較小。</p><div
