公司坐落于風(fēng)景秀麗、經(jīng)濟(jì)富饒、國際化城市 天津   是一家專業(yè)批發(fā)代理經(jīng)銷國外進(jìn)口液壓氣動(dòng)元件的開發(fā)型、貿(mào)易型公司，致力于經(jīng)營開品牌；是中國工業(yè)傳動(dòng)流體自動(dòng)化領(lǐng)域規(guī)模較大、的工業(yè)流體控制設(shè)備的代理商。我們有著豐富的氣動(dòng)液壓技術(shù)服務(wù)、工業(yè)銷售及國際采購的經(jīng)驗(yàn)，與國外眾多有著多年密切的業(yè)務(wù)聯(lián)系。同時(shí)，在歐美、日韓、澳洲和香港等地都有著長(zhǎng)期合作網(wǎng)點(diǎn)，我們還與國內(nèi)多家電廠，包裝廠，礦廠，設(shè)計(jì)研究院有著密切的合作關(guān)系。

溢流閥是一種液壓壓力控制閥,在液壓設(shè)備中主要起定壓溢流,穩(wěn)壓,系統(tǒng)卸荷和安全保護(hù)作用。溢流閥在裝配或使用中,由于O形密封圈、組合密封圈的損壞,或者安裝螺釘、管接頭的松動(dòng),都可能造成不應(yīng)有的外泄漏。 定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí),會(huì)使流量多年來為國內(nèi)成套配套，物資供應(yīng)部，各地機(jī)電市場(chǎng)提供大量的泵閥流體配件，儀器儀表，自動(dòng)化控制設(shè)備，工控伺服產(chǎn)品，工業(yè)成套器材等進(jìn)口備件。 我公司優(yōu)勢(shì)主打產(chǎn)品德國博世力士樂（BOSCH-REXROTH）工業(yè)液壓備件、氣動(dòng)元件、伺服工控配件等；對(duì)力士樂REXROTH工業(yè)產(chǎn)品有著穩(wěn)定渠道、種類齊全、正品保障、價(jià)格低 、供貨期短、售后服務(wù)有保證等優(yōu)勢(shì)，并已與國內(nèi)各大力士樂分銷商、生產(chǎn)配套廠、力士樂液壓系統(tǒng)使用客戶，建立了長(zhǎng)期供應(yīng)合作關(guān)系。并培養(yǎng)了一批具有專業(yè)素養(yǎng)的優(yōu)秀人才，能夠更好，更快的為你提供優(yōu)良的服務(wù)。長(zhǎng)期為國內(nèi)大中型企業(yè)、獨(dú)資、合資、外企提供各種進(jìn)口機(jī)械、儀器儀表、工控、電子等產(chǎn)品及疑難備品備件服務(wù)。因國內(nèi)眾多大中型企業(yè)所需進(jìn)口備件品種類型繁多，直接找每個(gè)訂貨在供貨期和價(jià)格上都不經(jīng)濟(jì)，找專業(yè)的進(jìn)口配件供應(yīng)商提供服務(wù)成為眾多用戶的選擇

用定量泵供油時(shí)，它與節(jié)流閥配合，可以調(diào)節(jié)和平衡液壓系統(tǒng)中的流量。在這種場(chǎng)合下，閥門經(jīng)常隨著壓力的波動(dòng)而開啟，油液經(jīng)閥門流回油箱，起著定壓下的溢流作用。

避免液壓系統(tǒng)和機(jī)床因過載而引起事故。在這種場(chǎng)合下，閥門平時(shí)是關(guān)閉的，只有負(fù)載超過規(guī)定的極*才開啟，起安全保護(hù)作用。通常，把的調(diào)定壓力比系統(tǒng)最高工作壓力調(diào)高10~20%

由先導(dǎo)溢流閥與二位二通電磁閥配合使用，可使系統(tǒng)卸荷。

　作遠(yuǎn)控調(diào)壓的閥用用管道將溢流閥的遙控口接到調(diào)節(jié)方便的遠(yuǎn)程調(diào)節(jié)閥進(jìn)口處，以實(shí)現(xiàn)遠(yuǎn)控目的

　　用換向閥將溢流閥的遙控口和幾個(gè)遠(yuǎn)程調(diào)壓連接， 即可實(shí)現(xiàn)高低多級(jí)控制。把先導(dǎo)式溢流閥回油口改為輸出壓力油的出口，并將壓力頂開錐形閥后原回油的通道堵列，使它經(jīng)過重新加工的泄油口流回油箱，這樣就可做順序閥用用于產(chǎn)生背將溢流閥串聯(lián)在回油路上，可以產(chǎn)生背壓，使執(zhí)行元件運(yùn)動(dòng)平衡。些時(shí)溢流閥的調(diào)定壓力低，一般用直動(dòng)式低壓澄流閥即可
