Description

Technical Field

[0001] This application relates to the field of hydraulic valve bodies, specifically to a novel integrated valve assembly. Background Technology

[0002] A central return integrated valve assembly is a hydraulic system component mainly used to integrate multiple hydraulic elements. It has functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. It can reduce pipeline connection points, reduce leakage risk, and simplify the maintenance process.

[0003] In existing related technologies, multiple hydraulic components need to be fixed to the valve seat with bolts during installation, which reduces installation efficiency and is not conducive to rapid maintenance later. Utility Model Content

[0004] To overcome the problem of installation efficiency of hydraulic components in the prior art, this application provides a novel integrated valve assembly.

[0005] This application adopts the following technical solution: a novel integrated valve assembly, including a valve seat and several valve bodies, wherein an inlet channel is provided inside the valve seat, several valve bodies are disposed on the valve seat and communicate with the inlet channel, an outlet channel is provided on the valve body, several slots are provided on the top of the valve seat, and the lower part of the valve body is adapted to be inserted into the slots;

[0006] The upper part of the side wall of the valve seat is provided with a pair of retaining strips and a limiting plate. The limiting plate is in contact with the side wall of the valve seat and can only move back and forth between the pair of retaining strips along the height direction of the valve seat.

[0007] The valve seat has a stop bar on the lower side wall, and a plurality of springs are provided between the stop bar and the limiting plate. The springs are used to push the limiting plate upward, and the limiting plate is used to cover the slot.

[0008] Optionally, the slot extends along the width direction of the valve seat, one end of the slot communicates with the side wall of the valve seat, and the bottom of the valve body is provided with a plug plate, which can be inserted into the slot from one end of the slot.

[0009] Optionally, the locking strip is L-shaped, with its vertical end connected to the side wall of the valve seat, and a sliding space existing between the horizontal end of the locking strip and the side wall of the valve seat, and the end of the limiting plate passing through the sliding space;

[0010] There is a distance between the top of the stop bar and the bottom of the limiting plate.

[0011] Optionally, the bottom of the limiting plate is provided with a first mounting hole, the top of the stop bar is provided with a second mounting hole, one end of the spring passes through the first mounting hole, and the other end of the spring passes through the second mounting hole.

[0012] Optionally, one end of the slot is provided with a ramp surface, which is used to guide the insert plate into the slot.

[0013] Optionally, a pair of limiting blocks are symmetrically provided on the lower part of the side wall of the limiting plate. When the insert plate is inserted into the slot, the top of the limiting block is in contact with the bottom of the card strip and the spring is in a state of not being fully compressed.

[0014] Compared with the prior art, this application has the following advantages:

[0015] 1. By pressing down on the limiting plate by the valve body, the limiting plate is pushed down, and the slot is exposed and open, making it easy to insert the insert plate into the slot and complete the installation of the valve body by pushing.

[0016] 2. After the insert plate is inserted into the slot, the spring pushes the limit plate to reset, and the limit plate covers the slot again, so that the slot is in the closed state, thereby realizing the limit and fixation of the valve body, reducing the difficulty of valve body installation, and facilitating quick replacement or maintenance in the future.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1-4As shown, a novel integrated valve assembly includes a valve seat 1 and several valve bodies 2. The valve seat 1 has an inlet channel 11. Several valve bodies 2 are disposed on the valve seat 1 and communicate with the inlet channel 11. The valve bodies 2 have outlet channels 21. The top of the valve seat 1 has several slots 12, and the lower part of the valve body 2 is adapted to be inserted into the slots 12. The upper part of the side wall of the valve seat 1 has a pair of retaining strips 3 and a limiting plate 4. The limiting plate 4 fits against the side wall of the valve seat 1 and can only move back and forth between the pair of retaining strips 3 along the height direction of the valve seat 1. The lower part of the side wall of the valve seat 1 has a stop strip 5. Several springs 6 are provided between the stop strip 5 and the limiting plate 4. The springs 6 are used to push the limiting plate 4 upward, and the limiting plate 4 is used to cover the slots 12.

[0024] Under the support of spring 6, the limiting plate 4 is at its high position, preventing the valve body 2 from being directly inserted into the slot 12. At this point, the lower part of the valve body 2 is placed on top of the limiting plate 4 and downward pressure is applied, allowing the limiting plate 4 to move downwards, thus opening the slot 12. Then, applying a pushing force in the extension direction of the slot 12 to the valve body 2 allows the lower part of the valve body 2 to be inserted into the slot 12. Once the valve body 2 is inserted into the slot 12, the downward pressure on the limiting plate 4 is released, and spring 6 pushes the limiting plate 4 upwards to reset, creating a sealing effect on the slot 12 and simultaneously limiting the insertion plate 22, ensuring the valve body 2 is reliably fixed within the slot 12. This two-step operation of pressing and pushing completes the assembly and fixing of the valve body 2, effectively improving the installation efficiency of the valve body 2 on the valve seat 1. During later maintenance, simply manually pressing down the limiting plate 4 allows for quick removal of the valve body 2, reducing maintenance difficulty.

[0025] The slot 12 extends along the width direction of the valve seat 1, and one end of the slot 12 communicates with the side wall of the valve seat 1. The bottom of the valve body 2 is provided with a slide plate 22, which can be inserted into the slot 12 from one end. The slide plate 22 and the slot 12 can be adapted to each other, that is, the slide plate 22 can be inserted into the slot 12 from one end, and the slide plate 22 can only move back and forth along the extension direction of the slot 12, and cannot be removed from the slot 12 along the height direction of the valve seat 1. This ensures that when the slide plate 22 is inserted into the slot 12 and one end of the slot 12 opening is closed by the limiting plate 4, the valve body 2 can be reliably fixed.

[0026] The retaining strip 3 is L-shaped. The vertical end of the retaining strip 3 is connected to the side wall of the valve seat 1. There is a sliding space between the horizontal end of the retaining strip 3 and the side wall of the valve seat 1. The end of the limiting plate 4 passes through the sliding space. There is a distance between the top of the stop strip 5 and the bottom of the limiting plate 4.

[0027] Under the limiting action of a pair of retaining strips 3, the limiting plate 4 can only move along the height direction of the valve seat 1 and can always maintain a state of contact with the valve seat 1. The stop strip 5 is set below the limiting plate 4, leaving space for the limiting plate 4 to move up and down. Furthermore, a protrusion can be set on the side of the horizontal end of the stop strip 5 facing the limiting plate 4. At the same time, a protrusion can also be set on the side of the limiting plate 4 facing the horizontal end of the stop strip 5. When the limiting plate 4 is pushed to the high position by the spring 6, the two protrusions are aligned and in contact. In this way, the tightness of the contact between the limiting plate 4 and the valve seat 1 can be improved by the compression between the two protrusions.

[0028] The bottom of the limiting plate 4 is provided with a first mounting hole 41, and the top of the stop bar 5 is provided with a second mounting hole 50. One end of the spring 6 passes through the first mounting hole 41, and the other end of the spring 6 passes through the second mounting hole 50. The first mounting hole 41 and the second mounting hole 50 ensure that the spring 6 can be reliably installed. Moreover, by increasing the depth of the first mounting hole 41 and the second mounting hole 50, the spring 6 can be prevented from bending during the up and down movement of the limiting plate 4, thereby ensuring that the spring 6 can reliably support and push the limiting plate 4.

[0029] One end of the slot 12 is provided with a ramp 13. The ramp 13 is used to guide the insert plate 22 into the slot 12. During the process of pressing down the valve body 2 and driving the limit plate 4 to move downward, when the insert plate 22 contacts the ramp 13, the insertion operation of the insert plate 22 can be performed without the need to precisely align the insert plate 22 with the slot 12, thus realizing the quick insertion of the insert plate 22.

[0030] A pair of limiting blocks 42 are symmetrically provided on the lower side wall of the limiting plate 4. When the insert plate 22 is inserted into the slot 12, the top of the limiting block 42 is in contact with the bottom of the retaining strip 3 and the spring 6 is in a state of incomplete compression. That is to say, under the limiting action of the limiting block 42, when the limiting plate 4 is at the high end under the push of the spring 6, the spring 6 is in a state of incomplete compression. In this way, the sealing effect of the limiting plate 4 on the slot 12 can be improved, thereby ensuring that the valve body 2 will not move in the slot 12, and maximizing the stability of the valve body 2 installation.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
