Throttle globe valve

A brief introduction:
JJM8 series Throttle stop valve Is a new type of throttling and cut-off and venting products, the valve with a cage fan Legion throttling, with multistage throttle throttle effect, characteristics of obvious effect, reliable sealing, convenient operation and maintenance, etc..
1, normally closed: valve seal for pressure in the seat on the ****, to form a hard seal, soft and embedded on the valve flap and the valve seat sealing surface is pressed to form second sealing, double sealing structure ensures zero leakage of the valve, then the valve clack opened balance hole in the closing and opening of the valve, when the valve is a small force, the valve open and closed with a small torque.
2, the slow pressure state: valve at the bottom of the left seat sealing surface, the valve clack is close to the bottom surface of the cage set at the bottom edge of the bad, the valve flap and the cage diameter to form a sealing sleeve. Without direct vent relief, so as to achieve the relaxation effect.
3, throttle state: valve bottom carbonyl left seat, further open, small valve to form a throttle, high speed fluid through slow pressure throttling directly after the flow of small valve and the valve sleeve formed at the window break flow reached two throttle valve sleeve, due to the edge of the window is cutting surface, high voltage dielectric direct scouring when the throttle channel, the valve at the bottom of the medium to change the eddy current, reduce the direct scouring medium valve seat seal, so as to avoid direct scouring medium, at the same time as the valve sealing surface is tapered, can blow the dirt and impurities and the valve seat sealing surface of the sealing surface protection, in order to prolong the service life of the valve.
4, fully open state: valve in the fully open state, the valve in full emptying, less resistance in fluid in the popular, shorten the venting time, improve the venting valve effect.
Two, Throttle stop valve The characteristics of:
1. manufacturing standards: GB/T12224-2005 JB/T7747-1995;
2. connection: connecting thread (NPT, G, Rc, Rp... );
