14 needle valve

Multi-function multiplex type high-pressure stainless steel needle valve and more integrate five type stainless steel needle valve on a body, can form a multipath controllable adjustable pathway, well solved the separation of valve set, the structure is loose, more complicated installation, more potential leakage points, the cost is high. Highly sealed type stainless steel needle valve 14 needle valve consists of body, valve cover, stem, handle, sealing ring, ring, air inlet, air flow and control on the valve body hole, hole with cooperate with the stem end to control the steps of the pore blocking, whose character is: control the hole on the steps with a thin wall funnel-shaped metal gasket. Funnel type metal gasket is made from have good ductility of metal. Such as can use pure copper, lead, soft and easy to deformation of the metal. Funnel type metal gasket at least one end is fixed in the upper and lower end of the wall of the valve body.
Type stainless steel needle valve body, valve cap, valve seat and valve stem, valve cap by screw set on the valve body, valve stem end through the bonnet vertical set in the valve body, valve stem set at the bottom of the disc, the valve is set at the bottom of the seat, disc and seat with Settings, product design for conical disc, seat set of products have cooperate with conical disc 38 needle valve set of tapered slot, the tapered slot setting products are circular groove, groove set up has sealed, the sealing seat set type O sealing ring; In the original seat set with the disc sealing ring, effectively reduce disc and seat hard contact, reduce wear stem and valve seat, delay service life, reduce maintenance costs.
Multi-function multiplex control type high-pressure stainless steel needle valve consists of body, the body connected with 5 type stainless steel needle valve, the first type stainless steel needle valve and the second type stainless steel needle valve set in the side of the body, the third type stainless steel needle valve and a fourth type stainless steel needle ball valve manufacturer valve on the other side of the body, the fifth type stainless steel needle valve set in front of the body; The body also set 6 connection hole; First connecting hole and the second connection hole set in upper body, the third connecting hole and a fourth connection hole in the front of the body, the fifth bore connection and sixth connection Settings on the under side of the body; The first connection holes respectively with the first type stainless steel needle valve and a second one port type stainless steel needle valve, the first type stainless steel needle valve and the second type stainless steel needle valve another port is respectively connected with the fifth hole and the third connecting hole connection; The second connection holes respectively with the third type stainless steel needle valve and a fourth type stainless steel needle valve port connection, the third type stainless steel needle valve and the fourth type stainless steel needle valve another port bore respectively connected to the fourth and sixth connection connection; The fifth type stainless steel needle valve two port bore respectively connected with the fifth and sixth connection connection.
