Double-clip Gapless Gate Valve
Principle
Double-clip type gapless gate valve consists of valve seat, valve liner, gate, support and driv-
ing device. Two valve seats make valve liner closely match under the action of assembly pre-
tightening force, forming a docking short pipe. When the valve is closed, the gate will wedge
between the two seat covers to cut the fluid, and closely match with the valve by the excellent
elasticity of Xinhai wear-resistant rubber valve liner to ensure the seal.
Features
The product has features of compact structure, small volume, light weight, convenient opera-
tion and maintenance, and is suitable for the occasions with particles or serious abrasion of
sediment. According to different pressure and corrosive state, the material of gate includes
stainless steel, ultra-high molecular weight polyethylene and the mixture between them. The
injection nozzle set on the valve body can reduce the gate friction and the valve open-close
torque;
The valve can be replaced with Xinhai rubber molded parts. Manual operation is generally used for Xinhai brake valve
products, according to the requirements of the users, power-driven and air operation can also be used. It can not only
be made on site but also be controlled remotely. Structure length and flange size can be determined usually according
to national standards, and can be also according to users’ requirements.
Application
Big open-close is used for double-clip type gapless gate valve, and is suitable for installing on hydrocyclones feeding,
tailings pipelines or double circuit lines to be as an on-off. The suitable medium includes pulp, ash slurry, acid and base
corrosive mediums.

Three-Way Automatic Check Valve
Principle
鑫
There are two slurry pumps produced, one is used for production, the other is used
for standby application. When one of the pumps and valves are opened, there will be
a serious congestion between the closed valve and tee joint neck, which causes the
difficulty in opening in the future. A tee joint automatic reversing valve is instead of
two valves. When opening one of them, the other one has no pulp.
Features
Three-way automatic check valve can save a pipe line input by just taking the price of
a valve, and can easily realize automation control;
The valve is lined with world-famous Xinhai wear-resistant rubber;
It is convenient, practical, and durable.
Application
It is used for pulp, slag, tailings, a variety of drainage systems of standby pump, and chemical corrosive medium.
