Detailed Description
In order to realize adjustable flow and small occupied space, a plug-in type two-position three-way valve structure with adjustable flow is designed.
Example (b):
as shown in fig. 1 and 2, the two adjustable plug-in flow three-way valves are vertically plugged in a mounting seat 8 and comprise caps 1, a shell 2, a valve 3, two damping cores 4, two check rings 6 and springs 7. Wherein the cap 1 comprises a cover plate, a first cylinder body and a second cylinder body, the lower end of the first cylinder body is open, the upper end of the first cylinder body is connected with the cover plate, the second cylinder body is positioned at the outer side of the first cylinder body, the upper end surface of the second cylinder body is connected with the side wall of the middle section of the first cylinder body, the upper section of the first cylinder body is provided with four cross through holes, the shell 2 is of a cylindrical structure which is open up and down, the shell 2 comprises a large end and a small end, wherein, main aspects and second barrel inner wall threaded connection, 2 middle sections lateral walls of casing are provided with a plurality of evenly distributed's through-hole, valve 3 is the columnar structure and is provided with the route with bottom terminal surface and lateral wall intercommunication, valve 3 and 2 main aspects inner walls movable seal of casing, a damping core 4 is fixed through a retaining ring 6 with 2 tip inner walls of casing, spring 7 cover is in the first barrel outside and one end and cap 1 contact, the spring 7 other end and valve 3 contact, another damping core 4 is fixed through another retaining ring 6 with first barrel inner wall.
The outer diameter of the cover plate of the cap 1 is larger than that of the second cylinder, and a sealing ring groove and a process hole for dismounting are arranged below the cap 1.
The outer wall surface of the shell 2 is also provided with two sealing ring grooves with different diameters, so that a lubricating oil inlet and an outlet flow passage are isolated, and the plug-in type two-position three-way valve with adjustable flow is convenient to disassemble.
The center of the connecting surface of the big end and the small end of the shell 2 is provided with a first through hole, and the damping hole on the damping core 4 is smaller than the first through hole.
The number of the passages of the valve 3 is three and the passages are uniformly distributed in the radial direction.
The damping core 4 is provided with damping holes, and the damping core is set to different specifications according to different sizes of the damping hole apertures.
A filter screen element 5 is arranged between the damping core 4 and the retainer ring 6.
The working principle is as follows:
1. oil enters the valve body from the inlet 1 and the inlet 2, the two ends of the valve are stressed differently due to the difference of the two oil pressure forces, and the valve has gravity. If the pressure of the first oil way is greater than that of the second oil way, the valve is stressed to have a downward operation trend, and the second oil way is sealed. At this point, the oil flows through the screen element for filtering and throttling through the damping core and finally exits through the outlet as shown in fig. 3. 2. If the second path of oil pressure is larger than the first path of oil pressure, the valve is forced to move upwards so as to cut off the first oil path, and the oil flows out from the outlet through the passage on the valve, as shown in fig. 4. 3. If the oil flow path needs to be changed, the damping core of the damping hole with the corresponding specification can be replaced by detaching the retainer ring. The orifice has a throttling function, and can adjust the flow of oil, so that the pressure of an oil path is changed, and the change of an oil flow path is realized, as shown in fig. 5.
