As for the implementation of the threaded connection, it will be explained in further detail in example 2 below.
As shown in fig. 4 to 6, an axial through hole 11 is provided in the axial valve body portion 1.
The radial valve body 2 has a first radial connecting end 12 and a second radial connecting end 13.
The first radial connecting end portion 12 is a mounting end portion of the valve body core 3, and the second radial connecting end portion 13 is a connecting end portion of a branch pipe in embodiment 2 described below. A radial through-hole 14 is provided in the radial valve body 2.
A communication hole 15 is provided between the axial through hole 11 and the radial through hole 14. When water passes through the axial through hole 11, the water in the axial through hole 11 enters the radial through hole 14 through the communication hole 15.
As shown in fig. 7, the valve body core 3 includes a core top cover 16, a compression spring 17, and a plunger 18.
Wherein, plunger 18 includes the end 19 of the plunger, plunger rod 20 and the afterbody 30 of plunger that link to each other in proper order, wherein:
the diameter of the plunger tip 19, plunger rod 20 and plunger tail 30 decreases in sequence.
In this embodiment 1, the plunger tip 19, the plunger rod 20 and the plunger tail 30 are connected by injection molding.

The stopper and stopper structure is configured to stopper the second radial connecting end portion side of the plunger 18 on the one hand, and to block the second radial connecting end portion 13 of the radial through hole 14 in cooperation with the plunger 18 on the other hand.
The following describes a specific structural form of the limiting and blocking structure:
as shown in fig. 5 and 6, the radial through hole 14 is sequentially provided with three sections of communicated cavities, namely a first cavity 22, a second cavity 23 and a third cavity 31, from the first radial connecting end 12 to the second radial connecting end 13.
The cross-sectional dimension of the first chamber 22 is the same as the diameter of the plunger tip 19, and the plunger tip 19 is located within the first chamber.
The cross-sectional dimension of the second cavity 23 is the same as the diameter of the plunger rod 20, and the plunger rod 20 is slidable along the second cavity 23.
The third cavity 31 has a cross-sectional dimension equal to the diameter of the plunger tail 30 which extends into the third cavity 31.
And a limiting boss 21 at the joint of the second cavity 23 and the third cavity 31, namely the limiting and blocking structure.
Specifically, the limiting and blocking principle of the structure is as follows:
the plunger 18 is inserted into the radial through hole 14 via the first radial connecting end 12, and when the tail 30 of the plunger is inserted into the third cavity 31, the bottom of the plunger rod 20 is just pressed against the surface of the limit boss 21, forming a limit and a seal.
At this time, the second radial connecting end portion 13 of the radial through hole 14 is closed, and water cannot flow out from the second radial connecting end portion 13.
The core cap 16 is provided with an external thread and the first radial connecting end portion 12 is provided with an internal thread.
The core cap 16 is mounted on the first radial connecting end portion 12.
The compression spring 17 is located between the core cap 16 and the plunger tip 19 of the plunger 18 and is in compression.
In the initial state, the compression spring 17 presses the plunger 18, so that the tail 30 of the plunger presses on the surface of the limit boss 21, and the second radial connecting end 13 of the radial through hole 14 is closed, as shown in fig. 5.
The radial valve body 2 is provided with an air hole 24, and air can be supplied into the radial through hole 14 through the air hole 24.
In the embodiment 1, the plunger 18 is pushed towards the first radial connecting end portion 12 by the air pressure generated when the air is supplied from the external air source, at this time, the tail portion 30 of the plunger leaves the third cavity 31 and moves towards the second cavity 23, so that the second radial connecting end portion 13 of the radial through hole 14 is opened, and the water can flow out from the second radial connecting end portion 13, as shown in fig. 6.
When the air pressure has disappeared, the plunger 18 is pushed, under the action of the compression spring 17, towards the second radial connection end 13, so as to close again the second radial connection end 13 of the radial through hole 14.
The air hole 24 is disposed at the connection between the first cavity 22 and the second cavity 23, as shown in fig. 6, the air entering through the air hole 24 can push the plunger 18 to move toward the first radial connecting end 12.
Of course, in order to ensure the close contact between the plunger 18 and the interior of the radial valve body 2, annular sealing grooves 25, 26 are provided in both the plunger head 19 and the plunger rod 20, and sealing rings are correspondingly mounted in the annular sealing grooves.
Compared with an electromagnetic control water valve, the pneumatic water valve in the embodiment 1 has the advantages of obviously improved safety and strong pressure bearing capacity.
Example 2
This embodiment 2 describes a water diversion apparatus, and the structure thereof is shown in fig. 8 to 12.
The water diversion device of this embodiment 2 includes a plurality of pneumatic water valves 27 as described in embodiment 1 above.
Wherein, the pneumatic water valves 27 are connected in series from front to back.
And the second axial connecting end part of the previous pneumatic water valve is connected with the first axial connecting end part of the next pneumatic water valve.
Because the pneumatic water valve in the embodiment 1, the first axial connecting end part and the second axial connecting end part both adopt detachable connectors, the quick connection between the adjacent pneumatic water valves is favorably realized, and the expandability is strong.
A branch line (not shown) is connected to each second radial connecting end 13.
In this embodiment 2, each branch line is independent from each other and does not interfere with each other, and when a certain pneumatic water valve is opened under pneumatic control, water passes through the branch line corresponding to the pneumatic water valve.
On the contrary, if a certain pneumatic water valve is not pneumatically controlled, no water passes through the branch pipeline corresponding to the pneumatic water valve.
The embodiment well realizes independent control of each branch pipeline.
As shown in fig. 8, 10 and 12, the first axial connecting end 4 of the most forward pneumatic water valve 27A is connected to a water inlet connector 28, and the second axial connecting end 5 of the most rearward pneumatic water valve 27B is connected to a plug 29.
The water enters the axial valve body part 1 of each pneumatic water valve in sequence through the water inlet pipe connector 28. When the number of branch pipelines needs to be increased or reduced, the plug 29 is only required to be removed, and a corresponding number of pneumatic water valves are connected or detached.
A branch pipeline is correspondingly connected to the second radial connecting end part 13 of each pneumatic water valve.
Therefore, the number of branch pipes in embodiment 2 can be increased or decreased as needed, and the expandability is good.
As shown in fig. 9 and 11, in order to realize the quick connection between the water inlet pipe connector 28 and the pneumatic water valve, and between the pneumatic water valve and the plug 29, one end of the water inlet pipe connector 28 and one end of the plug are designed as detachable connectors.
Wherein one end of the water inlet pipe joint 28 is a detachable joint which is matched with the first axial connecting end part 4. The other end of the inlet pipe nipple 28 may be threadably connected to an inlet pipe (not shown).
One end of the plug 29 is a detachable connector which is matched with the second axial connecting end part 5, and the other end is closed.
It should be noted that only three pneumatic water valves 27 are shown in fig. 8 to 12, however, the number of the pneumatic water valves 27 is not limited to three, and may be two, four, five or more.
The detachable connection in this embodiment 2 is, for example, the plug-in connection in the above embodiment 1, but may also be a threaded connection as shown in fig. 14 and fig. 15, that is, a threaded connection is used between two adjacent pneumatic water valves. Wherein,
the first axial connection end 4 is provided with an internal thread and the second axial connection end 5 is provided with an external thread matching the internal thread.
After the second axial connecting end portion 5 of the previous pneumatic water valve 27 is inserted into the first axial connecting end portion 4 of the next pneumatic water valve 27, the connection between the two adjacent pneumatic water valves 27 is quickly realized through threads.
However, the above two connection methods are merely exemplary, and other conceivable connection methods may also be employed.
Of course, the above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and it should be noted that any equivalent substitution, obvious modification made by those skilled in the art under the teaching of the present specification fall within the essential scope of the present specification, and the protection of the present invention should be protected.
