Integrated hand-operated direction valve

Abstract

The integrated manual reversing valve comprises a valve body, air inlet holes are formed in the centers of the front end and the rear end of the valve body, air outlet holes are formed in the top of the valve body at equal intervals, partition plates are installed at the front end and the rear end of the interior of the valve body, and through holes are formed in the partition plates at equal intervals. Baffles are installed on the sides, close to the air outlet holes, of the two sets of partition plates, and an adjusting mechanism for driving the baffles to move is installed on one side of the valve body. The valve handle rotates in the direction away from the valve body to drive the fixing plate to move in the direction close to the valve body, so that the connecting base pushes the adjusting plate to move in the direction towards the valve body to enable the baffle to move; therefore, when the baffle in one direction is damaged, the normal work of the other group cannot be hindered, the manual reversing valve can continue to work without being replaced by a new manual reversing valve subsequently, and a large amount of time is saved.

Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, specifically an integrated manual directional valve. Background Technology

[0002] Manual directional valves are core components in the field of fluid control. They are mainly used to control the flow direction of working fluids. In practical applications, slide valves are the most common type. A slide valve is a valve that changes the connection state of each channel port by sliding the valve core. The basic function of a directional valve is to change the flow direction of the working fluid.

[0003] The existing manual directional valves have a relatively simple fluid flow direction change. Once the valve core inside the valve is damaged or stuck, the manual directional valve will be damaged and unable to work properly. It will be necessary to replace it with a new manual directional valve to continue working, which will waste time.

[0004] Therefore, it is necessary to provide an integrated manual directional valve to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated manual reversing valve to solve the problems existing in the background technology. The technical solution of this utility model addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated manual reversing valve, comprising a valve body, wherein air inlets are provided at the center of both the front and rear ends of the valve body, air outlets are installed at equal intervals on the top of the valve body, partition plates are installed at both the front and rear ends inside the valve body, through holes are provided at equal intervals inside the partition plates, baffles are installed on the side of the two sets of partition plates near the air outlets, and an adjustment mechanism for driving the baffles to move is installed on one side of the valve body.

[0007] Preferably, the air outlet is connected to the center of the valve body, and the through hole is connected to the center of the valve body.

[0008] Preferably, a connecting plate is provided between the solid areas of the two sets of partition plates for connection.

[0009] Preferably, the baffle is composed of multiple connecting blocks, and the connecting blocks in the area of ​​the through hole near the air inlet have a blocking structure. Each of the connecting blocks in the area of ​​the through hole near the air inlet has three sets of connecting blocks on the side facing the adjustment mechanism.

[0010] Preferably, among the three sets of connecting blocks in the region of the through hole near the air inlet facing the adjustment mechanism, only one connecting block has a channel inside that communicates with the through hole.

[0011] Preferably, the adjusting mechanism includes a fixed seat with the front and rear ends of one side of the valve body installed. A fixed plate is rotatably connected to the inner side of the fixed seat. A valve handle is connected to the top of the fixed plate. Fixed blocks are connected to the front and rear ends of the fixed plate facing the valve body. Rotating rods are connected between the fixed blocks. A connecting seat is sleeved on the outer wall of the rotating rod. An adjusting plate penetrating one side of the valve body is connected to one side of the baffle. Extension blocks are installed at the front and rear ends of one side of the adjusting plate. The other end of the connecting seat is rotatably installed between the extension blocks.

[0012] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model allows the through hole closest to the valve handle to be opened when the baffle is moved one connecting plate distance away from the valve handle; the middle through hole can be opened when the baffle is moved two connecting plates distance away; and the through hole furthest from the valve handle can be opened when the baffle is moved three connecting plates distance away. Thus, the through holes at different positions can be opened by adjusting the movement distance of the baffle, while the through holes at other positions remain blocked.

[0015] This invention allows the fixed plate to move closer to the valve body by rotating the valve handle away from the valve body. This, in turn, causes the connecting seat to push the adjusting plate towards the valve body, thus moving the baffle. Furthermore, with air inlets at both the front and rear, damage to the baffle in one direction will not hinder the normal operation of the other group. No replacement of the manual directional valve is required for continued operation, saving a significant amount of time. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-5 An integrated manual directional valve includes a valve body 1. Air inlets 2 are provided at the center of both the front and rear ends of the valve body 1. Air outlets 3 are installed at equal intervals on the top of the valve body 1. Partition plates 4 are installed at both the front and rear ends inside the valve body 1. Through holes 5 are provided at equal intervals inside the partition plates 4. Baffles 6 are installed on the side of the two partition plates 4 near the air outlets 3. An adjustment mechanism 7 for driving the baffles 6 to move is installed on one side of the valve body 1.

[0025] like Figure 1-5As shown, the air outlet 3 is connected to the center of the valve body 1, and the through hole 5 is connected to the center of the valve body 1. By controlling the through hole 5 to connect with the air inlet 2, the fluid can be controlled to move towards the corresponding air outlet 3.

[0026] like Figure 1-5 As shown, the solid areas between the two sets of partition plates 4 are connected by a connecting plate 8. The three air outlets 3 are separated by the connecting plate 8, so that they do not affect each other during normal operation and there will be no problem of misaligned flow.

[0027] like Figure 1-5 As shown, the baffle 6 is composed of multiple connecting blocks 601. The connecting blocks 601 in the area of ​​the through hole 5 near the air inlet 2 are in a blocking structure. Three sets of connecting blocks 601 are provided on the side of the connecting blocks 601 in the area of ​​the through hole 5 near the air inlet 2 facing the adjustment mechanism 7. Under normal circumstances, all three sets of through holes 5 are in a blocked state. By adjusting the position of the baffle 6, the through hole 5 at the corresponding position is opened, so that the corresponding air outlet 3 works normally.

[0028] like Figure 1-5 As shown, among the three sets of connecting blocks 601 in the area of ​​the through hole 5 near the air inlet 2, only one connecting block 601 has a channel inside that communicates with the through hole 5. When the baffle 6 moves one connecting plate 8 distance away from the valve handle 703, the through hole 5 closest to the valve handle 703 will be opened. When the baffle 6 moves two connecting plates 8 distances, the middle through hole 5 will be opened. When the baffle 6 moves three connecting plates 8 distances, the through hole 5 furthest from the valve handle 703 will be opened. Thus, the movement distance of the baffle 6 can control the opening of the through holes 5 at different positions, while the through holes 5 at other positions are blocked.

[0029] like Figure 1-5As shown, the adjusting mechanism 7 includes a fixed seat 701 with the front and rear ends of one side of the valve body 1 installed. A fixed plate 702 is rotatably connected to the inner side of the fixed seat 701. A valve handle 703 is connected to the top of the fixed plate 702. Fixed blocks 704 are connected to the front and rear ends of the fixed plate 702 facing the valve body 1. A rotating rod 705 is connected between the fixed blocks 704. A connecting seat 706 is sleeved on the outer wall of the rotating rod 705. An adjusting plate 707 penetrating one side of the valve body 1 is connected to one side of the baffle 6. An extension block 708 is installed at the front and rear ends of one side of the adjusting plate 707. The other end of the connecting seat 706 is rotatably installed between the extension blocks 708. By rotating the valve handle 703 in the direction away from the valve body 1, the fixing plate 702 can be moved in the direction closer to the valve body 1. This causes the connecting seat 706 to push the adjusting plate 707 in the direction of the valve body 1, thus moving the baffle 6. Furthermore, since air inlets 2 are provided at both the front and rear, damage to the baffle 6 in one direction will not hinder the normal operation of the other group. It is not necessary to replace the manual directional valve to continue working, saving a lot of time.

[0030] Working principle: During use, by controlling the connection between the through hole 5 and the air inlet 2, the fluid can be controlled to move towards the corresponding air outlet 3. The three air outlets 3 are separated by the connecting plate 8, and they do not affect each other during normal operation, preventing misalignment of flow. Under normal circumstances, all three sets of through holes 5 are in a blocked state. By adjusting the position of the baffle 6, the corresponding through hole 5 is opened, allowing the corresponding air outlet 3 to work normally. When the baffle 6 moves one connecting plate 8 distance away from the valve handle 703, the through hole 5 closest to the valve handle 703 is opened. When the baffle 6 moves two connecting plate 8 distances, the middle through hole 5 is opened. The distance between the three connecting plates 8 is enough to open the through hole 5 furthest from the valve handle 703. Thus, the movement distance of the baffle 6 can control the opening of the through holes 5 at different positions, while the through holes 5 at other positions are blocked. By rotating the valve handle 703 in the direction away from the valve body 1, the fixed plate 702 is moved in the direction closer to the valve body 1, which in turn causes the connecting seat 706 to push the adjusting plate 707 in the direction of the valve body 1, thereby moving the baffle 6. Furthermore, with air inlets 2 provided at both the front and rear, damage to the baffle 6 in one direction will not hinder the normal operation of the other group. It is not necessary to replace the manual directional valve to continue working, saving a lot of time.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
