Abstract
The invention discloses a constant-pressure fuel gas distributing valve which is a fuel gas system for a plurality of burners, and more particularly relates to the constant-pressure fuel gas distributing valve for a torch system. The invention provides the constant-pressure fuel gas distributing valve with a simple structure, and safe and reliable operation. The fuel gas distributing valve comprises a valve body in which a piston provided with a sealing gasket is arranged; the valve body is structurally characterized in that: a limiting stopper is arranged outside the valve body at the upper end of a piston rod; the sealing gasket is arranged between the valve body and the piston rod; the valve body on the side of the piton rod is provided with a spring and a roll ball; the piston rod corresponding to the roll ball is provided with a positioning groove; the bottom of the valve body is provided with a gas inlet pipe; and the side of the valve body is provided with a gas outlet pipe adapting to different pressures.
Description
Technical field:
The present invention is the gas burning system that is used for multi-combustor, more definite relates to a kind of constant-pressure fuel gas distributing valve that is used for flare system.
Background technique:
In the fuel gas combustion system of existing multi-combustor, the work air feed of each burner is to realize that by solenoid valve or other switchings that automatically performs valve control is to combustion gas.
As shown in Figure 4, the combustion gas that pressure is arranged is through pipeline transmission, and the pressure transducer 400 that is located on the pipeline is passed to control system 300 to signal, and automatic valve 200 is opened or closed to control system 300 according to pressure condition, 100 work of control burner.
In existing multi-combustor system, generally all set a gaseous-pressure scope, low pressure range is generally at 2KPa-50KPa, and concrete numerical basis different situations determine that for flare system, pressure range is 2KPa-20KPa.
The existing combustion gas method of salary distribution comprises pressure transducer, control system, solenoid valve etc., its complex structure, cost height, is prone to fault, and reliability is lower; And because be the combustion gas occasion, charged parts have potential safety hazard.
Summary of the invention:
The present invention is exactly at the problems referred to above, and constant-pressure fuel gas distributing valve a kind of simple in structure, safe and reliable to operation is provided.
For achieving the above object, the present invention adopts following technological scheme, the present invention includes valve body, is provided with the piston with sealing gasket in the valve body, and its structure outline is that the valve body of piston rod upper end is outside equipped with limiting stopper, is provided with sealing gasket between valve body and the piston rod; The valve body of piston rod side is provided with spring, ball, is provided with positioning groove corresponding to the piston rod of ball; The bottom of valve body is a suction tude, and the side of valve body is provided with the steam outlet pipe that adapts to different pressures.
Beneficial effect of the present invention:
It is simple and reasonable for structure for distributing valve of the present invention, and a distributing valve of the present invention can replace several valve groups, and existing structure is greatly simplified; In addition, distributing valve of the present invention is entirely mechanically actuated, no live part, no potential safety hazard; And held stationary operation for a long time.

Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the B portion enlarged view of Fig. 1;
Fig. 4 is the structural representation of the fuel gas combustion system of existing multi-combustor.
Embodiment
The present invention includes valve body 1, be provided with the piston 2 with sealing gasket 3 in the valve body 1, the valve body 1 of piston rod 6 upper ends is outside equipped with limiting stopper 10, is provided with sealing gasket 9 between valve body 1 and the piston rod 6; The valve body 1 of piston rod 6 sides is provided with spring 11, ball 8, is provided with positioning groove 7 corresponding to the piston rod 6 of ball 8; The bottom of valve body 1 is a suction tude 5, and the side of valve body 1 is provided with the steam outlet pipe 4 that adapts to different pressures.
Can be respectively arranged with steam outlet pipe 4 in the both sides of valve body 1; So that adapt to the needs of output gas with various demand position.
Limiting stopper 10 can be with weight or spring, pneumatic replacement.
During use, combustion gas enters valve body 1 through suction tude 5, during underpressure, can not work.When the gaseous-pressure rising, pressure forces piston 2 to rise, and exposes corresponding steam outlet pipe 4, and combustion gas then is passed to burner by steam outlet pipe 4; Along with tolerance strengthens, pressure rises thereupon, and pressure forces piston 2 to continue to rise, and exposes corresponding steam outlet pipe 4 successively, and combustion gas is led to burner successively through steam outlet pipe 4, finishes level pressure distribution function.
