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.沟槽闸阀

1. Grooved gate valve

槽形闸阀广泛应用于自来水、污水、海水、水处理、、建筑、消防、石油、化工、电力、食品、医药、轻纺、造船、能源等行业的管线上作为调节和截流装置。沟槽闸阀具有开关轻便、密封可靠、弹性记忆好、使用寿命长等显着优点。槽形闸阀利用弹性闸板产生的微弹性变形的补偿作用，达到良好的密封效果。

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.

槽形闸阀阀板采用优异的橡胶将内外橡胶包裹在整体上。国外的橡胶硫化技术，使硫化阀板保证准确的几何尺寸，橡胶和球墨铸铁阀板牢固，不易脱落，具有良好的弹性记忆。沟槽闸阀是引进的生产技术，克服了沟槽闸阀橡胶老化、锈蚀阀门和柔性门弹性变形等问题。

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.

沟槽式闸阀的特点：(1)启闭省力。(2) 介质的流动方向不受限制，不会干扰流动和降低压力。(3) 流体阻力小，密封面受介质冲刷和侵蚀少。(4) 本实用新型形状简单，结构长度短，可制造性好，适用范围广。

Features of grooved gate valve: (1) labor saving opening and closing. (2) The flow direction of the medium is unrestricted, which will not interfere with the flow and reduce the pressure. (3) The fluid resistance is small, and the sealing surface is less scoured and eroded by the medium. (4) The utility model has the advantages of simple shape, short structural length, good manufacturability and wide application range.

2.沟槽式蝶阀

2. Grooved butterfly valve

具有安装快速、简单、可靠的特点，不受安装地点的限制，便于管道和阀门的维护，具有隔振、隔音的特点。在一定角度范围内，可克服管道不同轴连接产生的误差，温差引起的热膨胀和冷缩，密封性能可靠，不受介质注入的限制(双向密封)，溢流面积大，流阻系数小，流量大。广泛应用于流体输送管道，在排水、消防、空调、燃气、石油、化工、水处理、市政、造船等管道工程中用作控制流体。

It has the characteristics of fast, simple and reliable installation, is not limited by the installation location, is convenient for the maintenance of pipelines and valves, and has the characteristics of vibration isolation and sound insulation. Within a certain angle range, it can overcome the errors caused by the connection of different shafts of the pipeline, solve the thermal expansion and cold contraction caused by temperature difference, have reliable sealing performance, are not limited by medium injection (two-way sealing), have large overflow area, small flow resistance coefficient and large flow. It is widely used in fluid transmission pipeline and used as control fluid in pipeline engineering such as drainage, fire protection, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration, shipbuilding and so on.

沟槽式蝶阀的特点：(1)流通面积大，流阻系数小，流量大。(2) 蝶板采用整体橡胶制成，经久耐用。(3) 本实用新型结构紧凑，体积小，重量轻，操作灵活，维修方便。

Features of grooved butterfly valve: (1) large flow area, small flow resistance coefficient and large flow. (2) The butterfly plate is made of integral rubber and is durable. (3) The utility model has the advantages of compact structure, small volume, light weight, flexible operation and convenient maintenance.
