Detailed Description
The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
As shown in fig. 1, the present invention provides a gas control valve, which mainly comprises a valve body assembly 100 and a flow control assembly 120, and is suitable for various gas source pressures. The valve body assembly 100 includes a plurality of air passages therein, which are divided into a first part air passage and a second part air passage, which are used as an input air passage and an output air passage, respectively.
Example 1
As shown in fig. 2, 3 and 4, in the present embodiment, the first partial air passage and the second partial air passage are both single air passages. In the present embodiment, the second partial gas channel serves as a gas input end, and the first partial gas channel serves as a gas output end.
Valve body assembly 100 includes valve body 101, and the air flue all sets up in valve body 101. The valve body 101 is provided with a flow control assembly interface, and one end of each air passage is located in the flow control assembly interface.
The flow control assembly 120 includes: a valve stem 121, a coil 122, an elastic member 123, and a sleeve 124. The valve stem 121 is elastically connected to the inside of a sleeve 124 by an elastic member 123, and the coil 122 is circumferentially disposed on the sleeve 124. The elastic member 123 may be a spring or the like capable of providing a desired elastic force.
In a natural state, the valve rod 121 is hermetically connected to one end of the first partial air passage under the elastic force of the elastic member 123, and a space between the sleeve 124 and the valve rod 121 is communicated with one end of the second partial air passage.
For better sealing, a flat gasket 126 is provided on the valve stem 121 at a position contacting the first partial air passage.
To facilitate replacement, the valve body assembly 100 and the flow control assembly 120 are removably attached, such as by threads. A seal 125, such as a gasket, is provided at the junction of the valve body assembly 100 and the flow control assembly 120. An internal thread is arranged in the flow control assembly interface, an external thread is arranged on the sleeve 124, and the flow control assembly 120 is screwed on the flow control assembly interface through the external thread. The end of the first part air passage is a protruding structure in the flow control assembly interface, a corresponding groove is formed in the valve rod 121, and the protruding structure extends into the groove and is in contact sealing with the inner wall of the groove in a sealing state. Therefore, the valve rod 121 can better seal the first partial air passage, and meanwhile, a certain exhaust space is provided for the second partial air passage.
The valve body 101 is provided with an input/output interface, and the other end of each air passage is respectively positioned in one input/output interface and is used for being connected with an external air source and a pipeline.
The using method comprises the following steps:
the other end of second air flue is connected the air supply, and the gas of air supply gets into in the space between pole 121 and the sleeve pipe 124 through the second air flue for the pressure all around of valve rod equals, relies on the pressure of elastic component self this moment to guarantee to extrude the valve rod the tip at first partial air flue, makes it sealed.
When the coil 122 is energized, the generated electromagnetic force in the direction opposite to the elastic force of the elastic member 123 moves the valve rod 121 against the elastic force of the elastic member 123, so that the valve rod is separated from the contact with the first partial gas passage, and the gas in the second partial gas passage can enter the first partial gas passage and be output.
After the output of the gas is completed, the coil 122 is not energized, and the valve rod 121 can be tightly attached to the end of the first partial gas channel again under the action of the elastic member 123 and the gas pressure of the gas source, so that the first partial gas channel is sealed again. At the moment, if the air pressure in the first partial air passage is greater than the combination of the air pressure in the second partial air passage and the elastic force of the elastic member, the air can push the valve rod 121 to reversely flow back to the second partial air passage from the first partial air passage until the air pressure in the first partial air passage is less than the combination of the air pressure in the second partial air passage and the elastic force of the elastic member, and the valve rod is sealed again, so that the function of controlling and protecting the upper limit of the output air pressure is achieved, and the inflated object is well protected from being over inflated.
Example 2
As shown in fig. 5, in this embodiment, on the basis of embodiment 1, the number of the first partial air passages and the second partial air passages is designed to be plural, and the operation principle is the same as that of embodiment 1.
However, those skilled in the art will appreciate that in other embodiments, the first partial air passage may be designed as a plurality of the second partial air passages, or the first partial air passage may be designed as one of the first partial air passages and the second partial air passages may be designed as a plurality of the first partial air passages and the second partial air passages. The design can be designed by the person skilled in the art according to the actual situation.
Example 3
In this embodiment, on the basis of embodiments 1 and 2, the second partial gas channel is used as a gas output end, and the first partial gas channel is used as a gas input end.
At this time, the proper elastic member 123 needs to be replaced according to the air pressure of the air source, so that the elastic force of the elastic member 123 in a natural state can overcome the air pressure of the air source, and the valve rod 121 is prevented from being pushed by the air source. When the gas valve needs to be opened, the coil 122 is also electrified, and the generated electromagnetic force in the direction opposite to the elastic force of the elastic member 123 enables the valve rod 121 to move against the elastic force of the elastic member 123, so that the valve rod is separated from the contact with the first partial gas channel, and the gas in the first partial gas channel can enter the second partial gas channel and be output.
The utility model discloses a valve body, coil isotructure realize in different service environment, control the air supply of different pressure, make gas control more have advantages such as safe and reliable, low energy environmental protection, range of application are wide, two-way control, small-size portable, low cost, long service life.
