It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1-6, some embodiments of the present invention provide an angle valve comprising: a valve seat 1, a pilot valve body 2, and an elastic member 3.

The pilot valve body 2 is installed on the valve seat 1, an air inlet 20, a first pilot head 22, a first pilot port 24, a third cavity 26 and a movable pilot valve piston 28 are arranged on the pilot valve body 2, the air inlet 20 is communicated with the third cavity 26 through the first pilot port 24, the first pilot head 22 is used for opening and closing the first pilot port 24, the pilot valve piston 28 is movably arranged in the third cavity 26, a sealing head 29 is arranged at one end of the pilot valve piston 28, and the sealing head 29 is used for opening and closing the communication port 15.
The elastic piece 3 is used for pushing the pilot valve piston 28 so that the sealing head 29 seals the communication port 15; wherein, with the first pilot port 24 opened, fluid entering from the air inlet 20 enters the third chamber 26 and pushes the pilot valve piston 28 to move, so that the sealing head 29 is separated from the communication port 15.
The inventor of the present invention has found in long-term practice that some impurities are easily accumulated in the fluid passage of the existing angle valve at the working port, thereby causing abnormal situations such as seizing. The inventor finds that the main reason for the occurrence of the situation is that the right angle exists in the fluid channel of the existing angle valve, and the impurity is easily accumulated at the right angle, so that abnormal situations such as clamping and the like occur. The two working ports, i.e. the first working channel 10 and the second working channel 12, of the angle valve provided by the present invention have a certain included angle (60-80 degrees), e.g. 70 degrees, with the movable cavities (i.e. the first cavity 14 and the second cavity 16) of the pilot valve piston 28. Furthermore, when the angle valve provided by the invention works, a right angle does not exist in the fluid channel, and impurities are not easy to accumulate in the working port, so that abnormal conditions such as clamping and the like can be effectively prevented. In addition, the angle valve provided by the invention can be installed with an angle when being installed, the fluid resistance in the valve seat 1 is small, working fluid (such as air) is saved, and large-flow fluid can be simultaneously communicated in the first working channel 10 and the second working channel 12.
Further, in some embodiments of the present invention, referring to FIG. 3, the axis of the first working channel 10 is parallel to the axis of the second working channel 12. Furthermore, the pilot valve body 2 of the angle valve provided by the embodiment has a certain included angle with the valve seat 1, so that the space can be saved during installation.
It will be appreciated that in the angle valve provided by the present invention, the first pilot head 22 is used to open or close the first pilot port 24, and thus, the present invention is not limited in particular to the specific structure and kind of the first pilot head 22, and various pilot structures commonly used in the art may be adopted.
In some embodiments of the present invention, referring to fig. 2, first guide head 22 includes a first coil 221, a first stationary core, and a first movable core 222; the first movable iron core 222 is movably arranged on the first guiding opening 24; when the first coil 221 is energized, the first movable core 222 is attracted by the first stationary core to open the first pilot port 24. Further, in some embodiments provided by the present invention, referring to fig. 2, a first pressing plate 223 is provided between the first pilot head 22 and the pilot valve body 2.
That is, in this embodiment, the first pilot 22 is an electromagnetic pilot valve, and its main working principle and other structures are known to those skilled in the art, and the present invention will not be described herein.
The working process of the angle valve provided by the invention is briefly described below by taking an electromagnetic pilot valve as a first pilot head 22 and taking the angle valve as a vacuumizing valve as an example:
In a state where the first coil 221 is not energized, the first pilot port 24 is closed by the first plunger 222, and the air supply entering from the air inlet 20 of the pilot valve body 2 cannot reach into the third chamber 26, and therefore, the pilot valve piston 28 is pushed by the elastic force of the elastic member 3, so that the sealing head 29 is pressed against the communication port 15, thereby closing the communication port 15, and at this time, the first working channel 10 and the second working channel 12 are disconnected. When the first coil 221 is energized, the first movable iron core 222 is attracted by the first static iron core, so as to open the first pilot port 24, after the air supply entering from the air inlet 20 of the pilot valve body 2 enters the third cavity 26, the air pressure in the third cavity 26 gradually increases, and the pilot valve piston 28 is pushed to move after overcoming the elastic force of the elastic member 3, so that the sealing head 29 is separated from the communication port 15, so as to open the communication port 15, and at this time, the first working channel 10 and the second working channel 12 are communicated.
That is, in the angle valve provided by the present invention, the on-off between the first working channel 10 and the second working channel can be controlled by the first guide head 22 and the elastic member.
Further, in some embodiments of the present invention, referring to fig. 1-2, the pilot valve body 2 is further provided with a second pilot head 23 and a second pilot port 25; the first working channel 10 communicates with the intake port 20 through the second pilot port 25. Furthermore, the second working channel 12 of the angle valve provided in this embodiment may be connected to an external vacuum pump or other vacuum pumping device, and the first working channel 10 may provide a vacuum pumping function. When the angle valve of this embodiment is used as a vacuumizing valve, the second guide head 23 can be used for breaking the vacuum in the first working channel 10, and the working process can be briefly described as follows:
As described above, when the first coil 221 is energized, the first pilot port 24 is opened, and the supply air introduced from the air inlet 20 of the pilot valve body 2 pushes the pilot valve piston 28 to move, so that the sealing head 29 is separated from the communication port 15, and the first working channel 10 and the second working channel 12 are communicated. Since the second working channel 12 is externally connected with a vacuum pumping device (e.g., a vacuum pump), air in the first working channel 10 is pumped away to form a vacuum working environment, and thus, a workpiece, such as a mobile phone, can be adsorbed through the first working channel 10. Then, after the first coil 221 is powered off, the sealing head 29 is pressed against the communication port 15 again due to the elastic force of the elastic member 3, so as to close the communication port 15, and further disconnect the first working channel 10 and the second working channel 12, at this time, the first working channel 10 is always kept in a vacuum state, and further, the workpiece can be stably adsorbed, and the external vacuum pumping device does not need to be kept in a working state all the time. After the second pilot head 23 opens the second pilot port 25, since the first working channel 10 is communicated with the air inlet 20 through the second pilot port 25, the air (such as air) supplied through the air inlet 20 of the pilot valve body 2 enters the first working channel 10, so as to break the vacuum environment in the first working channel 10, and the adsorbed workpiece can be separated.
In this embodiment, the first pilot port 24 and the second pilot port 25 both supply air through the air inlet 20 on the pilot valve body 2, that is, the first pilot head 22 and the second pilot head 23 share one air inlet, so that the structure of the pilot valve body 2 is greatly simplified, the installation is more convenient, and the cost is saved.
It is also understood that in this embodiment, the second guide head 23 is used to open or close the second guide port 25, and thus, the present invention is not particularly limited in the specific structure and kind of the second guide head 23, and various guide structures commonly used in the art may be employed.
In some embodiments of the present invention, referring to fig. 2, the second guide head 23 includes a second coil 231, a second stationary core, and a second movable core 232; the second movable iron core 232 is movably arranged on the second guiding opening 25; when the second coil 231 is energized, the second movable iron core 232 is attracted by the second stationary iron core to open the second pilot port 25. Further, in some embodiments provided by the present invention, referring to fig. 2, a second pressing plate 233 is provided between the second pilot head 23 and the pilot valve body 2. That is, in this embodiment, the second pilot head 23 is also an electromagnetic pilot valve, and its main working principle and other structures are well known to those skilled in the art, and the present invention will not be described herein.
Further, referring to fig. 2-3, in some embodiments of the present invention, the pilot valve body 2 is further provided with a fourth cavity (not shown in the drawings) and a manual button 5 for sealing the fourth cavity, and the fourth cavity 4 is in communication with the third cavity 26. That is, in this embodiment, the manual button 5 may be controlled to allow the third chamber 26 to communicate with the atmosphere to exclude high-pressure gas in the third chamber 26, and the sealing head 29 closes the communication port 15 under the elastic force of the elastic member 3 to disconnect the first working channel 10 and the second working channel 12.
It will be appreciated that the present invention is not particularly limited to the specific air passage arrangement inside the angle valve, and various air passage connection structures may be arranged in the valve seat 1 and the pilot valve body 2 according to actual requirements, as long as the above-described working process can be achieved.
For example, fig. 5 and 6 show a gas path structural arrangement of the pilot valve body 2 and the inside of the valve seat 1 of the angle valve according to an embodiment of the present invention, wherein the gas path F in the pilot valve body 2 is communicated with the gas path G in the valve seat 1 when the pilot valve body 2 is mounted on the valve seat 1.
Referring to fig. 5, it can be seen that when the first pilot port 24 is opened, after the gas enters from the gas inlet 20, the gas sequentially passes through the gas path a, the gas path H, the first pilot port 24, the gas path I, the gas path J and the gas path K to reach the third cavity 26, so as to push the pilot valve piston 28 disposed in the third cavity 26 to move, thereby achieving the purpose of controlling the on-off of the first working channel 10 and the second working channel 12.
After the pilot valve piston 28 moves and opens the communication port 15, the first working channel 10 and the second working channel 12 communicate, and further, the first working channel 10 can realize positive pressure work under the condition that the second working channel 12 supplies positive pressure gas; the first working channel 10 can be operated under negative pressure with the second working channel 12 being evacuated. Further, the first working channel 10 can realize alternate positive and negative pressure operation.
Referring to fig. 5 and 6, when the second pilot port 25 is opened, the gas enters from the gas inlet 20, and then sequentially passes through the gas path a, the gas path B, the second pilot port 25, the gas path C, the gas path D, the gas path E, the gas path F, and the gas path G to reach the first working channel 10, and then, the vacuum state in the first working channel 10 may be broken under the condition of vacuum pumping. Meanwhile, by opening the second pilot port 25, ventilation is continued after breaking the vacuum in the first working channel 10, positive pressure can be provided to the first working channel 10, and positive pressure operation of the first working channel 10 can be achieved.
It will be appreciated that in the angle valve provided by the present invention, the main function of the elastic member 3 is to push the pilot valve piston 28 to move by using its own elastic force, so that the sealing head 29 presses against the communication port 15, thereby closing the communication port 15 to disconnect the communication state between the first cavity 14 and the second cavity 16, thereby disconnecting the first working channel 10 and the second working channel 12, and therefore, the present invention is not limited to the elastic member 3, and various elastic members commonly used in the art can be adopted. For example, in some embodiments of the invention, the elastic member 3 is a spring. Meanwhile, in the angle valve provided by the invention, the sealing head 29 seals the communication port 15 in an extrusion type sealing mode, so that the sealing effect is good.
It will be appreciated that the sealing head 29 may be provided at one end of the pilot valve piston 28 in a variety of configurations, as the application is not particularly limited in this regard. Referring to fig. 3, in some embodiments of the application, a sealing head 29 is coupled to a pilot valve piston 28 by a connecting rod 27.
