Details
The QZFM pneumatic insulation combination valve features lightweight, reliable sealing, and compact size, mainly used for synchronous gravel sealing vehicles, effectively preventing asphalt leakage, making the entire asphalt circulation system more automated.
Pressure level: 1MPa ;
Operating temperature: -20C-240°C ;
Applicable medium: high viscosity non-corrosive media such as asphalt;
The QZFM pneumatic insulation combination valve mainly consists of asphalt inlet, left outlet, control port, right outlet, and return tank port, controlling the pipeline through the opening and closing of the cylinder to achieve control of asphalt flow.
It has the following characteristics:
1. The valve body insulation chamber is cast in one piece, with a simple process, large insulation contact area, and good effect; the sealing at the valve rod uses a two-stage seal to improve sealing reliability.
2. The support seat has a sealing protection chamber, and the sealing pressure cover is installed at the bottom of the sealing protection chamber. The top of the sealing protection chamber is equipped with a dust ring and a sealing ring. This effectively prevents a small amount of leaking asphalt and dust from entering the cylinder, affecting its normal operation.
.
a simple structure and stable performance. Both the front and rear of the pump are equipped with insulation chambers, allowing gas or liquid to be used as a heat carrier to heat and insulate the pump, making it particularly suitable for transporting high-viscosity media. This series of insulated gear pumps has two inlet and outlet configurations: left inlet and right outlet, and right inlet and left outlet, with the same installation dimensions and strong interchangeability.
