Description

Technical Field

[0001] The invention relates to a hydraulic control valve, in particular to a plate-type valve and a plate-type functional valve group. Background Art

[0002] Directional valves are a common type of valve in the hydraulic field. They are divided into tubular valves, cartridge valves, plate valves, stacking valves, and disc valves according to different installation methods. Among them, disc valves have an absolute advantage in space occupancy due to array installation and sharing of P and T channels, but their disadvantages are also very obvious - the functions are relatively single. Most disc valves are directional valves, and unlike stacking valves, they cannot stack multiple functional valves on the basis of reversing through the oil circuit design in the bottom integrated block, which greatly limits the application scope of disc valves. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a pressure and flow dual proportional valve and a vulcanizer plate-type hydraulic valve group using the same. The vulcanizer plate-type hydraulic valve group using the pressure and flow dual proportional valve eliminates the complex and bulky integrated block, which not only greatly shortens the oil circuit but also further reduces the manufacturing cost.

[0004] The technical solution adopted by the present invention is: a plate valve, including a valve body, the valve body including a valve core hole, an oil inlet channel, an oil return channel that pass through the mounting surfaces on both sides, and two working oil ports, at least one of the two working oil ports is arranged on the mounting surface, and the valve core hole is perpendicular to the oil inlet channel and the oil return channel.

[0005] The disc valve is characterized in that: the mounting surface is also provided with a pilot port connected to the oil circuit where the working oil port is located.

[0006] A disc-type functional valve group including a disc-type valve, characterized in that it also includes a functional valve block, the functional valve block is provided with a cartridge valve hole and an external working oil port, the external working oil port is connected to the working oil port of the disc-type valve mounting surface, the cartridge valve hole is correspondingly provided with inlet and outlet oil channels, a cartridge valve is arranged in the cartridge valve hole, and the cartridge valve is arranged on the oil path between the external working oil port and the working oil port of the disc-type valve mounting surface.

[0007] The said disc-type functional valve group is characterized in that: the said plug-in valve hole is also provided with a corresponding pilot oil passage, and the pilot oil passage is connected with the pilot port of the disc-type valve.

[0008] The plate-type functional valve group is characterized in that the functional valve block is provided with an oil inlet channel and an oil return channel penetrating through the mounting surfaces on both sides.

[0009] The plate-type functional valve group is characterized in that the cartridge valve is an electromagnetic ball valve.

[0010] The plate-type functional valve group is characterized in that the cartridge valve is a counterbalance valve.

[0011] The present invention transforms the existing disc valve to provide a basis for connecting a functional valve block, and adds a functional valve block on the valve body mounting surface, so that the working oil port of the disc valve has more extended functions.

DETAILED DESCRIPTION

[0032] Embodiment 1:

[0033] like Figure 1-8 As shown, a disc-type functional valve group includes a disc-type valve 1 and a first functional valve block 2. The working surfaces on both sides of the disc-type valve 1 are penetrated by an oil inlet channel 101 and an oil return channel 102, the valve core hole 103 is arranged perpendicular to the oil inlet channel 101 and the oil return channel 102, and the first working oil port 104 is arranged on the front working surface. In this embodiment, the disc-type valve 1 is an electromagnetic reversing valve, a reversing valve core is installed in the valve core hole 103, and electromagnets are arranged on both sides of the valve core hole 103. The valve body of the disc-type valve 1 is a modification of a standard disc-type valve body, specifically, the second working oil port 105 is originally located on the same working surface as the first working oil port 104. In this embodiment, the second working oil port 105 is arranged on the mounting surface corresponding to one side of the first functional valve block 2. Since its axial relative position with the valve core hole 103 is unchanged compared with the standard valve body, the oil circuit function of the second working oil port 105 remains unchanged.

[0034] The mounting surface at the top of the first functional valve block 2 is provided with a plug-in oil inlet hole 201 corresponding to the second working oil port 105, and a plug-in valve hole 202 is opened on the side end surface, and an electromagnetic ball valve 3 is inserted in the plug-in valve hole 202. The plug-in oil inlet hole 201 is connected with the tail of the plug-in valve hole 202, that is, it is connected with the oil inlet at the tail of the electromagnetic ball valve 3. The front end of the plug-in valve block 2 is provided with a third working oil port 203 on the same side as the working surface of the disc valve 1. The third working oil port 203 is connected with the middle part of the plug-in valve hole 202, that is, it is connected with the oil outlet in the middle of the electromagnetic ball valve 3.

[0035] Through the above connection, the disc valve 1 with the reversing function is connected to the execution end through the first working oil port 104 and the third working oil port 203, and the third working oil port 203 is added with the function of opening / closing the working oil port on one side. This embodiment is the case where the disc valve 1 is a tail-connected valve. At this time, the first functional valve block 2 itself does not have an oil inlet / return passage. If the disc valve 1 is not a tail-connected valve, the first functional valve block 2 needs to be provided with an oil inlet / return passage like the disc valve 1. As shown in the figure, the positions of the plug-in oil inlet hole 201, the plug-in valve hole 202, and the third working oil port 203 do not interfere with the newly opened oil inlet / return passage of the first functional valve block 2.

[0036] Embodiment 2:

[0037] like Figure 9-16 As shown, a disc type functional valve group includes a disc type valve 1 and a second functional valve block 5. Compared with the first embodiment, the disc type valve 1 in this embodiment is added with a pilot oil port 106 connected to the first working oil port 104, and the pilot oil port 106 and the second working oil port 105 are located on the same surface.

[0038] The second functional valve block 5 is provided with a third oil inlet channel 511 and a third oil return channel 512. The third oil inlet channel 511 and the third oil return channel 512 are through holes that penetrate the upper and lower end surfaces, ensuring that the oil inlet / return channels of the disc valve 1 and the disc valve on the other side are connected. The rear end is provided with a third counterbalance valve installation hole 513, and the left end is provided with a third plug-in working oil port 514. The bottom of the second functional valve block 5 is provided with a third plug-in oil inlet port 517 and a third plug-in pilot port 518. The third plug-in oil inlet port 517 is connected to the second working oil port 105 of the disc valve 1, and the third plug-in pilot port 518 is connected to the pilot oil port 106 of the disc valve 1.

[0039] By arranging a counterbalance valve at the two working oil ports of the connecting plate valve 1, stable operation of the execution end is achieved.
