Embodiment
Following examples are used to illustrate the utility model, but are not used for limiting protection domain of the present utility model.
Shown in Fig. 1-2, Fig. 1 is described rotary-type selector valve structural representation, and Fig. 2 is the A-A cross-sectional schematic of Fig. 1.Rotary-type selector valve comprises valve body 4, drive unit 1, main valve body 9, and valve body 4 communicates with main valve body 9, and is orthogonal with the medial axis of the two, and the two can connect as one by flange and Stamping Steel Ribbon.Main valve body 9, valve body 4 are cylindric, and valve body 4 also can be square.
Establish dividing plate 8 in the main valve body 9, dividing plate is separated into two chambeies (C chamber, D chamber) with main valve body 9, can establish pipeline in addition like this, makes facility compact, has made full use of the space.
In the valve body 4, and main valve body 9 wherein be provided with valve plate 3 between a chamber (C chamber), valve plate 3 is made up of two orthogonal semicircular plates, the semi-circular ends of valve plate 3 is taken on valve seat 4.The surface of Sealing 5 contacts with valve plate 3, can guarantee can seal between valve plate 3 and the valve seat 10.
Valve plate 3 is fixed on the live axle 6 of drive unit 1, and valve plate 3 is fixing by pin 2 with live axle 6.Drive unit 1 is controlled automatically by electrical equipment, drives valve plates 3 rotation up and down in valve body 4 by live axle 6, changes the valve plate position repeatedly.Drive unit 1 can be any one in the mechanism that pneumatic (hydraulic pressure or electronic) final controlling element of double-action (single-acting) type or cylinder and straight journey change rotation into, is well known equipment.
The another side of valve seat 10 is provided with valve body dividing plate 7, is connected with dividing plate 8 by valve body dividing plate 7.
The surface of sealing lays respectively at that it is the mutually vertical outer surface of (perhaps angle) each other.The center of gravity of valve plate vertical side valve plate when limit position is not on shaft centre line, but the side opened of valve plate relatively, this shape is easy to processing, has reduced the torque of drive unit, has increased circulation area.This valve plate commutating speed is fast, and its sealing is to be out of shape and to form at the Sealing that the limit position compressing is arranged in valve body and valve seat by valve plate.
The valve body 4 of rotary-type selector valve can one (shown in Fig. 7,8), is two-position three-way valve; Also can be two (shown in Fig. 3-6), is two position four-way valves.When being two position four-way valves, two valve body 4 interior valve plates 3 are in opposite position under the control of drive unit 1, guarantee that flue gas and air can not mix, and walk different passages.
With two position four-way valves is example, and the concrete working procedure of rotary-type selector valve is:
Shown in Fig. 3,4, when the valve plate 3 of valve body 4 is positioned at upside, air draught enters from the empty side E of valve plate mouth, enter heat-accumulating box (figure does not mark) along D chamber, main valve body 9 middle and lower part place, then C chamber, 9 middle and upper part is drawn out to the valve body 4 ' of relative position to flue gas from heat-accumulating box portion along main valve body, and valve plate 3 ' is positioned at downside, flue gas is drawn from the F mouth, the position of valve plate 3 ' and valve plate 3 is just in time opposite, has both blocked the bottom air draught, can draw flue gas again.
Otherwise after the drive unit commutation, live axle 6 rotates to an angle through certain hour, (for example 90 degree), shown in Fig. 5,6, when the valve plate 3 of valve body 4 was positioned at downside, air draught entered from valve plate 3 empty side M mouths, the place enters heat-accumulating box along C chamber, main valve body 9 middle and upper part, then D chamber, 9 middle and lower part is drawn out to the valve body 4 ' of relative position to flue gas from heat-accumulating box portion along main valve body, and valve plate 3 ' is positioned at the position opposite of upside and valve plate 3, blocked the upper air air-flow, can draw flue gas from the N mouth again.
Change valve plate position (driving device controls is by electrical equipment control automatically certainly) repeatedly by drive unit 1 like this, will make flue gas and air enter and draw valve body repeatedly,, satisfy the needs of recuperative heater to reach the purpose of accumulation of heat.
Fig. 7 looks sectional view for two-bit triplet selector valve master, and Fig. 8 looks schematic representation for the left side of Fig. 7.When the valve plate 3 of valve body 4 was in downside, air entered along C chamber, main valve body 9 middle and upper part from the air intlet of main valve body 9, sends heat-accumulating box to from the F mouth; On the contrary, when the valve plate 3 of valve body 4 was in upside, flue gas was discharged from the D mouth from drawing from heat-accumulating box along main valve body 9 middle and lower parts, along with valve plate constantly shift one's position with the flue gas intermittent type draw, the air intermittent type enters to reach the accumulation of heat purpose.
Fig. 9 is the schematic representation of existing cut-off type selector valve, and the cut-off type selector valve of same size is compared with rotary-type selector valve, and is bulky many, also heavy many of weight, and general rotary-type selector valve is approximately littler by 2/3rds than cut-off type selector valve volume, and weight is wanted gently half.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that the utility model is protected.
