Description
Technical field
The utility model relates to valve body field, particularly a kind of Novel steam reduction valve.
Background technique
Steam reducing valve is mainly used in chemical field; when protected intrasystem pressure exceedes the Set pressure of steam reducing valve; steam reducing valve is opened and is carried out release to system; anti-locking system internal pressure continues raise and damage system; after system internal pressure reduces; steam reducing valve returns seat, prevents intrasystem medium from continuing discharge and wasting energy.
But steam reducing valve of the prior art, mostly complex structure, cost is higher, and does not have preconditioning ability, may cause the follow-up larger waste of medium in system.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of Novel steam reduction valve, and to solve the complex structure caused in prior art, cost is higher and cause the above-mentioned multinomial defects such as larger waste.
For achieving the above object, the utility model provides following technological scheme: a kind of Novel steam reduction valve, comprise valve body, one end of described valve body is provided with valve gap, the other end is provided with air outlet, the side of described valve body is provided with connecting tube, piston is provided with in described connecting tube, the outer wall of described valve body is provided with pre-conditioning unit, described pre-conditioning unit comprises fixing frame, fixed plate, connecting rod and motion bar, the lower end of described fixing frame is provided with sealing cover, the outer wall of described valve body is provided with aperture, described sealing cover is arranged on aperture, described connecting rod is arranged between fixing frame and fixed plate, one end of described motion bar is connected with fixed plate, the other end is connected with piston through the outer wall of valve body, spring is provided with in described valve body, described spring is arranged on motion bar.
Preferably, described air outlet is provided with unidirectional baffle plate.
Preferably, the end face of described unidirectional baffle plate and air outlet is at 45 ° hinged.
Preferably, described valve body is provided with air pressure alarm.
Preferably, the upper end outer wall of described connecting tube is provided with some exhaust ports.
The beneficial effect of above technological scheme is adopted to be: the Novel steam reduction valve of the utility model structure; simple and reasonable; with low cost, when protected intrasystem pressure has just exceeded the Set pressure of steam reducing valve, under the influence of air pressure; promotion piston moves forward; and then promotion motion bar moves forward, therefore, fixing frame is by jack-up; sealing cover is separated with aperture and plays preconditioning effect, avoids the waste causing system larger.

Wherein, 1-valve body, 2-valve gap, 3-air outlet, 4-connecting tube, 5-piston, 6-fixing frame, 7-fixed plate, 8-connecting rod, 9-motion bar, 10-sealing cover, 11-aperture, 12-spring, the unidirectional baffle plate of 13-, 14-air pressure alarm, 15-exhaust port, 16-pressure piping.
Embodiment
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows embodiment of the present utility model: a kind of Novel steam reduction valve, comprise valve body 1, one end of described valve body 1 is provided with valve gap 2, the other end is provided with air outlet 3, the side of described valve body 1 is provided with connecting tube 4, piston 5 is provided with in described connecting tube 4, the outer wall of described valve body 1 is provided with pre-conditioning unit, described pre-conditioning unit comprises fixing frame 6, fixed plate 7, connecting rod 8 and motion bar 9, the lower end of described fixing frame 6 is provided with sealing cover 10, the outer wall of described valve body 1 is provided with aperture 11, described sealing cover 10 is arranged on aperture 11, described connecting rod 8 is arranged between fixing frame 6 and fixed plate 7, one end of described motion bar 9 is connected with fixed plate 7, the other end is connected with piston 5 through the outer wall of valve body 1, spring 12 is provided with in described valve body 1, described spring 12 is arranged on motion bar 9.
In the present embodiment, unidirectional baffle plate 13 is installed in air outlet 3, unidirectional baffle plate 13 can only externally be opened, prevent introduced contaminants from entering in valve body 1, affect valve body 1 using effect, unidirectional baffle plate 13 is at 45 ° hinged with the end face of air outlet 3, by the downward water conservancy diversion of steam of discharging, hurt sb.'s feelings during prevention exhaust, valve body 1 is installed air pressure alarm 14, remind staff, the very first time removes air pressure larger in processing system, in order to avoid cause serious adverse consequences, the upper end outer wall processing of connecting tube 4 is with some exhaust ports 15, under nature, exhaust port 15 is positioned at the top of piston 5, when piston 5 is shifted onto the top of exhaust port 15 by air pressure, air pressure is discharged from exhaust port 15, play the effect of predischarge decompression.
Based on above-mentioned: valve body 1 is arranged on the pressure piping 16 of system by connecting tube 4, in connecting tube 4, piston 5 is installed, piston 5 plays the effect of sealing, when protected intrasystem pressure is in the Set pressure of steam reducing valve, in system, steam circulation is normal, when protected intrasystem pressure has just exceeded the Set pressure of steam reducing valve, under the influence of air pressure, promote piston 5 to move forward, and then promotion motion bar 9 moves forward, therefore, fixing frame 6 is by jack-up, sealing cover 10 is separated with aperture 11, in this process, aperture 11 1 aspect plays the effect of pre-decompression exhaust, on the other hand, the Set pressure making staff be easy to perceive intrasystem pressure just to have exceeded steam reducing valve, the very first time goes to regulate source of the gas, avoid follow-up larger waste, when intrasystem pressure continues to increase, when having exceeded the Set pressure of steam reducing valve, piston 5 leaves connecting tube 4, air pressure is discharged from aperture 11 and air outlet 3, release is carried out to system, after system internal air pressure reduces, piston 5 enters in connecting tube 4 under the effect of spring 12, fixing frame 6 is equally also driven to reset, aperture 11 is blocked by sealing cover 10, prevent intrasystem steam from continuing discharge and wasting energy.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
