Abstract
The utility model relates to a sewage drainage valve, comprising a Y-shaped valve body (1), a valve cover (10) on the branch pipe of the Y-shaped valve body, and a valve rod (6) in the valve cover. A fluid inlet and a fluid outlet are arranged on the other branch pipe of the Y-shaped valve body (1), and a valve seat (2) and a valve clack (3) are installed on the outlet end of the other branch pipe of the Y-shaped valve body (1). The sewage drainage valve is characterized in that the valve seat (2) is provided with two circulation holes, and two circulation holes which are corresponding to the valve seat are arranged on the valve clack (3). The valve rod (6) passes through the valve cover (10). The upper part of the valve rod (6) is connected with a handle (15), and the lower part of the valve rod (6) is connected with the valve clack (3).
Description
The utility model relates to blowoff valve, and specifically a kind of valve body is the quick draining valves that opening is arranged on Y type, the valve seat.
Being widely used in the quick draining valves of industrial boiler system at present, is a kind of parallel double-flashboard valve that utilizes the rack-and-pinion transmission, sees accompanying drawing 3, and this valve has two shortcomings.1, utilize the rack-and-pinion transmission, complex structure and stuck is easily operated dumb; 2, the flap valve seat can produce uneven wear in switching process, has shortened service life.
The purpose of this utility model is to provide a kind of simple in structure, flexible operation, the quick draining valves of long service life.
Its main technical schemes comprises valve gap (10) and the interior valve rod (6) of valve gap on Y-valve body (1) and its arm, on another arm of Y-valve body (1), fluid inlet and outlet is arranged, and valve seat (2) and flap (3) are installed at its port of export, two openings are arranged on valve seat (2), two openings corresponding with valve seat are arranged on the flap (3), valve rod (6) passes valve gap (10), and the top of valve rod (6) is connected with handle (5), and the bottom is connected with flap (3); Straight pin (5) on there is a groove on flap (3) top and is installed in valve rod (6) cooperates, and a cavity of placing spring (4) is arranged in the lower end of valve rod (6).
The utility model has the advantages that because the switching of adopting valve seat with holes and flap to come control valve is compared with traditional rack-and-pinion transmission parallel double-flashboard structure to have simple in structurely, switch is flexible, characteristics such as long service life.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the A-A figure of Fig. 1.
Fig. 3 is existing valve body structure figure.
Shown in Figure 2 as Fig. 1:
Valve gap (10) and valve rod (6) are arranged on an arm of Y-valve body (1), the outer end of valve rod (6) utilizes taper pin (14) to connect handle (15), utilize straight pin (5) to be connected behind the cavity of inner insertion flap (3) upper end with flap, place spring (4) in the cavity of valve rod lower end, so that flap (3) is close on the valve seat (2), the connecting portion of valve rod and valve gap has the filler (8) and pad (7) that seals, gland above the filler (13) utilizes bolt (11) and locking nut (12) to be connected with valve gap (10), also there is the pad (9) that seals junction at valve gap (10) and valve body (1), on another arm of Y-valve body, advancing of fluid arranged, outlet, valve seat (2) is fastened on the port of export of valve body, (also can with this end as entrance point), two openings are arranged on valve seat, two corresponding with it openings are also arranged on flap.
Claims (2)
1, a kind of plane rotation quick draining valves, comprise the valve gap (10) on Y-valve body (1) and its arm, and the valve rod (6) in the valve gap, on another arm of Y-valve body (1), fluid inlet and outlet is arranged, and valve seat (2) and flap (3) are installed, it is characterized in that valve seat (2) has two openings at its port of export, two openings corresponding with valve seat are arranged on the flap (3), valve rod (6) passes valve gap (10), and the top of valve rod (6) is connected with handle (15), and the bottom is connected with flap (3).
2, blowoff valve according to claim 1 is characterized in that the straight pin (5) of flap (3) top on one groove being arranged and being installed in valve rod (6) cooperates, and has a cavity of placing spring (4) in the lower end of valve rod (6).
