H44TC Ceramic Swing Check Valve product Overview
H44TC Ceramic Swing Check Valve produced and sold by Baigang valve group is suitable for power generation industrial hydraulic coal conveying, hydraulic ash removal and mud conveying system with working temperature ≤200 ℃, working medium of slag water> 1: 5 and maximum particle size ≤50mm. As a one-way opening and closing device, Prevent media backflow.

H44TC Ceramic Swing Check Valve features

Structural ceramic sealing surface wear, scratch resistance; 
impact design, reduce noise, protect the sealing surface; 
suitable for horizontal pipeline 
swing-type ceramic check valve Applicable conditions: for oil, metallurgy, mining, coal, cement industrial plants and sewage Processing system, suitable for conveying. Swing type ceramic check valve Technical Specifications: 1. Way: Swing; Swing Nominal pressure: Class 150 to 600; Nominal size: 2 "to 24"; Suitable temperature. : -40 to 350 degrees Celsius Connection type: Flange.

H44TC Ceramic Swing Check Valve works

Check valve is to prevent the media back to the automatic valve, the fluid flows from the inlet side to the outlet side. The check valve flap opens under the action of fluid pressure, the media backwards rely on the self-weight valve or auxiliary agencies automatically shut down to prevent the media backflow protection device policy operation. The valve disc, valve seat sealing surface of the material are made of structural ceramics to improve the wear resistance and erosion resistance of the valve, greatly extending the service life. The product has no impact on the valve seat structure to protect the seat impact resistance.

The series of valves used in the power plant dry ash system warehouse pump inlet and outlet doors, can also be used for mining, chemical and other wear and tear of dry ash, slag and other media pipeline check device. Nominal pressure of 1.0MPa and 1.6MPa, to adapt to the temperature ≤ 200 ℃.

The valve closed in any direction all sealed. Body bonnet with WCB castings or stainless steel castings. Sealing surface with a hard seal. The valve material mouth full flow unobstructed, wear resistance grab, sealing performance, start the load of small ash card and ash phenomenon is less.

The valve uses high-grade ceramic seal has been tough, high mechanical strength, wear resistance and long service life. Compact structure can be installed at any angle.

H44TC Ceramic Swing Check Valve performance advantages

Ceramic check valve toughened ceramic material used as a sealing material, corrosion resistance, high temperature, abrasion and erosion resistance and better performance. Specifically, there are some advantages: all the parts in contact with the medium are structural ceramic materials, its chemical stability and high hardness (Rockwell hardness HRC90), second only to diamond; ceramic good wear resistance, so that the valve Durable, high reliability, long service life, is 2-4 times that of titanium alloy valve and Monel valve; The valve has high wear resistance, corrosion resistance, erosion resistance and good insulation; available In the high hardness of the granular media; can be used for a variety of complex conditions, more professional! Can be used for soft particles but corrosive media; low cost, long service life, cost-effective; For the above two media, the valve has an unparalleled absolute advantage, is currently the only suitable medium valve.

 
H44TC Ceramic Swing Check Valve installation instructions

Do not allow the check valve in the pipeline to bear weight, large check valve should be independent support, so that the system from the impact of pressure. Vertical lift check valve should be installed in the vertical pipe. Lifting horizontal flap check valve should be installed in the horizontal pipe.　　　

When installing the check valve, pay special attention to the flow direction of the medium so that the normal flow direction of the medium matches the direction of the arrow indicated on the body or the normal flow of medium will be cut off. Bottom valve should be installed at the bottom of the pump suction pipe. Swing check valve installation location is not properly restricted, usually installed in the horizontal pipe, but can also be installed in the vertical pipe or pouring pipe. The general type lift check valve should be installed on the horizontal pipe, vertical lift check valve and the bottom valve is generally installed in the vertical pipe, and the medium flows from bottom to top. Single-flap swing check valve is generally suitable for medium-diameter occasions. Selection of large-diameter pipe single swing check valve, in order to reduce water hammer pressure, it is best to reduce the pressure of the water hammer slow closing check valve. Double valve swing check valve for medium and large diameter pipe. Double-flap swing check valve on the structure of small, light weight, is a fast-growing check valve; multi-valve swing check valve for large-diameter pipe.
