德國洛克進口立式止回閥進口球閥工作穩(wěn)定可靠經久耐用  

 一、進口立式止回閥描述：

德國LOCKE洛克進口立式止回閥，采用立式結構，加彈簧止回，通常用于豎立安裝的止回閥。正常處于關閉狀態(tài)，由于管線中進口端介質的壓力作用，而克服彈簧阻力使閥門開啟。當進口端介質壓力低于出口端時，彈簧將閥芯推向閥座而使閥門關閉，阻止介質逆流，故起止回作用。 本閥門由于采用彈簧支撐閥芯，故采用立式安裝或臥式裝均可。廣泛使用于化工、液化石油氣、流體等行業(yè)。

The vertical check valve imported from Locke lock, Germany, adopts vertical structure and spring check, which is usually used for vertical installation. Normally in the closed state, the valve is opened by overcoming the spring resistance due to the pressure of the medium at the inlet end of the pipeline. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat to close the valve and prevent the medium from flowing back, so it plays a check role. The valve adopts spring-loaded valve core, so it can be installed vertically or horizontally. Widely used in chemical industry, liquefied petroleum gas, fluid and other industries.

6. Application fields: mechanical equipment, chemical equipment, general parts, industrial equipment, water supply and drainage equipment, papermaking equipment, pharmaceutical equipment, general equipment, petrochemical equipment, power equipment, gold powder equipment mining equipment, municipal, electronic industry and other fields.

三、進口立式止回閥結構特點：

1、閥瓣行程短，靈敏性高，大大減少了閥瓣關閉所需時間，有效降低了止回閥的水錘壓力。

2、密封面采用合金鋼或硬質合金，密封副材料配對合理，使用壽命長。

1. The valve disc has short stroke and high sensitivity, which greatly reduces the time required for closing the valve disc and effectively reduces the water hammer pressure of the check valve.

2. The sealing surface is made of alloy steel or cemented carbide, and the materials of sealing pair are matched reasonably, with long service life.
