Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The schematic diagram of the still bottom valve that accompanying drawing 1 provides for the utility model preferred embodiment;
Wherein: 1, valve body; 2, discharge port; 3, screw rod; 4, valve pocket; 5, flap; 6, opening; 7, handwheel; 8, flange plate; 9, Stuffing box; 10, stiffening rib.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the still bottom valve described in the present embodiment, comprises valve body 1, discharge port 2 and screw rod 3, in described valve body 1, offers valve pocket 4, and wherein the cross section of valve pocket 4 is arc surfaced; Described discharge port 2 is fixed on the sidewall of valve body 1, and with respect to the downward-sloping setting of shaft centre line of valve pocket 4, described discharge port 2 is connected with the bottom of valve pocket 4 in valve body 1, makes valve body 1 and discharge port 2 form a passage.Be appreciated that this reactor is in the process of specific design, this valve body 1 can be arranged to integral structure with discharge port 2, as this discharge port 2 is fixed on valve body 1 by the mode of welding.
Described screw rod 3 is through valve body 1, and in this screw rod and valve body 1, the contact position of valve pocket 4 is arranged on the top of passage between discharge port 2 and valve pocket 4; In the time that this reactor is applied on reactor, the required material discharging is under the effect of gravity, it can directly flow to discharge port 2 and discharge, this still bottom valve is in the process using like this, as long as there is the existence of material in this still bottom valve, it will give off completely from discharge port 2, has avoided being detained in still bottom valve.
