Description
Technical Field
The utility model relates to a valve, in particular to an automatic-opening and closing material blowing assisting valve for pneumatic conveying.
Background
The pneumatic conveying system is characterized in that powder or granules are conveyed through a pipeline by utilizing compressed gas and is widely applied to related fields of thermal power, chemical food and the like, however, no matter any conveying process or conveying method is used for a certain time, the conveying efficiency is reduced due to the increase of pipeline damage or other reasons, the pipeline is blocked or the conveying amount is reduced, and therefore, a conveying blowing assisting device is additionally arranged on the pipeline.
The existing blow-assisting valve mainly has two types, one type is electrically and mechanically combined, mechanical start and stop are carried out by utilizing pipeline pressure signal feedback, the other type is mechanical principle such as piston motion, and start and stop actions are carried out by triggering under certain pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of overcoming the defects in the prior art and provides the material blowing assisting valve for pneumatic conveying, which has a simple structure and is triggered by pressure difference and automatically opened and closed.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an automatic pneumatic conveying of switching helps blows valve with material, includes valve body and valve gap, be equipped with intake pipe and outlet duct on the valve body, be equipped with elastic diaphragm between valve body and the valve gap, the last pressure balance hole that is equipped with of elastic diaphragm, form the surge chamber between elastic diaphragm and the valve gap, be equipped with canceling release mechanical system in the valve gap, canceling release mechanical system is connected with elastic diaphragm, and the pressure difference of elastic diaphragm both sides makes elastic diaphragm jack-up, and the intake pipe is linked together with the outlet duct.
Further, the reset mechanism is a spring, and a guide groove for mounting the spring is formed in the valve cover.
Furthermore, the air inlet pipe is positioned on the side wall of the valve body, and the air outlet pipe is positioned below the elastic diaphragm.
Furthermore, the top of guide way is equipped with adjusting nut, the one end of spring is installed on adjusting nut, and its other end is connected with elastic diaphragm. The pressure difference between two sides required when the elastic diaphragm is jacked up or reset can be adjusted by the adjusting nut.
When the pressure of the air outlet pipe is higher than that of the buffer chamber, the pressure difference generated on the two sides of the elastic diaphragm is jacked up, so that the air inlet pipe is communicated with the air outlet pipe, and the air in the air inlet pipe can be led to the air outlet pipe; in the process that the pressure difference between the two sides of the elastic diaphragm is gradually reduced, the spring can drive the elastic diaphragm to slowly reset until the air inlet pipe is not communicated with the air outlet pipe.
The utility model has simple structure, does not need to use other linkage devices, independently partitions the air inlet space and the air supplementing space, utilizes the pressure difference larger than the elastic force of the spring, automatically triggers, and can automatically reset after the pressure is balanced.

FIG. 2 is a schematic structural diagram of an embodiment of the utility model after opening of a blow-assist valve;
FIG. 3 is a schematic diagram of the process of the present invention.
In the figure: 1. the valve comprises a valve body, 2, a rubber diaphragm, 3, a pressure balance hole, 4, a spring, 5, a guide groove, 6, an adjusting nut, 7, a buffer chamber, 8, an air inlet pipe, 9, an air outlet pipe, 10 and a valve cover.
Detailed Description
The utility model is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1-2, this embodiment includes valve body 1 and valve gap 10, be equipped with intake pipe 8 and outlet duct 9 on the valve body 1, be equipped with rubber diaphragm 2 between valve body 1 and the valve gap 10, be equipped with pressure balance hole 3 on the rubber diaphragm 2, form buffer chamber 7 between rubber diaphragm 2 and the valve gap 10, be equipped with spring return mechanism in the valve gap 10, spring return mechanism includes spring 4, guide way 5 and adjusting nut 6, and in buffer chamber 7 in the valve gap 1 was located to guide way 5, adjusting nut 6 installed on the top of guide way 5, and the one end of spring 4 is connected with rubber diaphragm 2, and the other end of spring 4 is installed on adjusting nut 6, utilizes adjusting nut 6 can adjusting spring 4's elasticity size to control rubber diaphragm 2 by jack-up or the size of required pressure difference in both sides when reseing. When the pressure difference that intake pipe 8 and outlet duct 9 produced is greater than the elasticity that spring 4 predetermine, rubber diaphragm 2 is by jack-up, and intake pipe 8 is linked together with outlet duct 9, and after the pressure balance of intake pipe 8 and outlet duct 9, rubber diaphragm 2 resets under the effect of spring 4, and intake pipe 8 no longer communicates with outlet duct 9.
In this embodiment, the air inlet pipe 8 is located on the side wall of the valve body 1, and the air outlet pipe 9 is located below the elastic diaphragm 2.
As shown in fig. 3, the bin pump is started, the powder gradually enters the ash conveying pipe, normal conveying is realized, no large resistance loss is generated, the pressure of the ash conveying pipe is the same as that of the air source, meanwhile, the pressure of the air in the air inlet pipe 8 is kept the same as that of the buffer chamber 7 through the pressure balancing hole 3, and the blowing-assisting valve does not work. Along with the increase of conveying capacity, the resistance loss gradually increases along the way, the internal pressure of the ash conveying pipe begins to rise, pressure difference is generated on two sides of the rubber diaphragm 2, the rubber diaphragm 2 is jacked up by the compression spring 4, the air inlet pipe 8 is communicated with the air outlet pipe 9, and the external blowing-assisted air source enters the air outlet pipe through the air inlet pipe. After the blowing-assisting valve is opened for a working cycle, the internal pressure of the ash conveying pipe is reduced, the pressures of the two ends of the air inlet pipe 8 and the air outlet pipe 9 of the blowing-assisting valve are the same, the blowing-assisting valve stops working, the powder continues to move forwards, and the next blowing-assisting valve starts to work. And so on.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are also within the scope of the present invention provided they are within the scope of the claims of the present invention and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
