The opening and closing part of the grooved gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The sealing of grooved soft seal gate valve has two kinds: self sealing and forced sealing. The sealing surface can only be sealed with medium pressure, that is, the sealing surface of the ram can be pressed to the valve seat on the other side with medium pressure to ensure the tightness of the sealing surface, which is self sealing. Forced sealing means that when the gate valve is closed, the gate shall be forced to the valve seat by external force to ensure the tightness of the sealing surface.

Difference between grooved gate valve and grooved butterfly valve

1.溝槽閘閥

1. Grooved gate valve

槽形閘閥廣泛應(yīng)用于自來(lái)水、污水、海水、水處理、環(huán)保、建筑、消防、石油、化工、電力、食品、醫(yī)藥、輕紡、造船、能源等行業(yè)的管線上作為調(diào)節(jié)和截流裝置。溝槽閘閥具有開關(guān)輕便、密封可靠、彈性記憶好、使用壽命長(zhǎng)等顯著優(yōu)點(diǎn)。槽形閘閥利用彈性閘板產(chǎn)生的微彈性變形的補(bǔ)償作用，達(dá)到良好的密封效果。

Grooved gate valves are widely used in pipelines of tap water, sewage, seawater, water treatment, environmental protection, construction, fire protection, petroleum, chemical industry, electric power, food, medicine, light textile, shipbuilding, energy and other industries as regulating and intercepting devices. Grooved gate valve has the advantages of light switch, reliable sealing, good elastic memory, long service life and so on. Groove gate valve uses the compensation function of micro elastic deformation produced by elastic gate to achieve good sealing effect.

槽形閘閥閥板采用優(yōu)異的橡膠將內(nèi)外橡膠包裹在整體上。國(guó)外的橡膠硫化技術(shù)，使硫化閥板保證準(zhǔn)確的幾何尺寸，橡膠和球墨鑄鐵閥板牢固，不易脫落，具有良好的彈性記憶。溝槽閘閥是引進(jìn)先進(jìn)的生產(chǎn)技術(shù)，克服了溝槽閘閥橡膠老化、銹蝕閥門和柔性門彈性變形等問(wèn)題。

The grooved gate valve plate adopts excellent rubber to wrap the inner and outer rubber on the whole. Foreign rubber vulcanization technology ensures the accurate geometric size of vulcanized valve plate. Rubber and nodular cast iron valve plates are firm, not easy to fall off and have good elastic memory. Grooved gate valve introduces advanced production technology, which overcomes the problems of rubber aging, corrosion and elastic deformation of flexible gate valve.
