In figure: 1. square flange, 2. dial, 3. handle, 4. valve body, 41. inlet passages, 42. subchannels, 5. reducer pipe, 6. round flange, 7. baffle plate, 8. rotating shaft, 9. end cap.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, this coal powder distribation valve, comprise square valve body 4, valve body 4 comprises the inlet passage 41 and subchannel 42 that are connected, and subchannel 42 is symmetrically arranged two, and inlet passage 41 1 end is provided with square flange 1, the inlet passage the other end arranges two openings, two openings are connected with the Single port of two subchannels respectively, and another port, two subchannels 42 is connected with reducer pipe 5, and the outer end of reducer pipe 5 is provided with round flange 6.
Be provided with the baffle plate 7 be fixed in rotating shaft 8 in inlet passage 42, be connected, be convenient to axis of rotation between rotating shaft with valve body by bearing, baffle plate can along with rotating shaft synchronous axial system; Valve body is provided with the end cap 9 in gap between closed inlet passage and rotating shaft, and bearing covers by end cap 9.
The steel plate of square valve body 4 structure adopts wearing plate, and be that built-up welding forms, have wear-resisting characteristic, the timber intensity that more traditional coal dust distributing valve equipment uses is higher, and the life-span is longer; Further, also on the inwall of valve body, sulfuration can have wear-resisting rubber layer, increase the service life.
Rotating shaft 8 one end is positioned at inlet passage outside and is connected with handle 3, is convenient to the position of controllable register 7 by handle 3; Inlet passage outside is provided with the dial 2 corresponding with handle, and dial 2 is by support fixed valve body, and dial 2 is positioned at the below of handle 3 end.
Rotating shaft 8 is located in the middle part of inlet passage, and two subchannels are positioned at rotating shaft both sides and arrange, and by flapper, can control the openings of sizes of two subchannels by rotating shaft.
