Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a combinable plunger-type multi-way distribution valve. Background Technology

[0002] The existing multi-way valve structure is basically a rotary drive, such as multi-way ball valves and flat multi-way valves. They all adopt vertical inlet and outlet forms such as top inlet and side outlet or side inlet and top outlet. Multi-way ball valves realize one inlet and one outlet, and flat multi-way valves realize multiple inlets and multiple outlets, but they are limited to low-pressure environments.

[0003] Piston-type multi-way distribution valves are based on angle piston valves, retaining the advantages of piston valves such as high flow rate and no dead zone, and realizing one-way or multi-way distribution, achieving functions such as fluid distribution and switching. Piston-type multi-way distribution valves typically use vertical inlet and outlet forms, such as top inlet and side outlet or side inlet and top outlet, to achieve one inlet and one outlet or one inlet and multiple outlets. To achieve multiple inlets and one outlet, it is necessary to increase the number of valves and the installation space, which is not suitable for use in small spaces. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a combinable plunger-type multi-way distribution valve. This plunger-type multi-way distribution valve adopts a planar inlet and outlet, which not only realizes multiple inlets and one outlet or one inlet and multiple outlets, but also realizes the stacking of multiple units, saving installation space and cost.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a combinable plunger-type multi-way distribution valve, including a plurality of multi-way distribution valves stacked in sequence. The multi-way distribution valve includes a valve body and a plurality of plunger valves. A first through hole is provided inside the valve body. A plurality of valve blocks are horizontally arranged along the circumference of the first through hole for connecting to the plurality of plunger valves one by one. A second through hole is horizontally arranged inside the valve block for moving the drive end of the plunger valve. The second through hole communicates with the first through hole. A third through hole is horizontally arranged on one side of each of the plurality of valve blocks for communicating with the second through hole. A fourth through hole is horizontally arranged on the other side of one of the valve blocks for communicating with the first through hole.

[0006] In one embodiment, the valve body of the combinable plunger-type multi-way distribution valve is provided with a plurality of positioning holes, which are located outside the first through hole and are not connected to the first through hole.

[0007] In one embodiment, the number of valve blocks of the combinable plunger-type multi-way distribution valve is four.

[0008] In one embodiment, the plunger valve of the combinable plunger-type multi-way distribution valve includes an actuator, a piston rod, and a plunger. The actuator is connected to the valve block via a column assembly. The drive end of the actuator is connected to the piston rod. The piston rod is connected to the plunger via a connecting assembly. The plunger slides in fit with a second through hole in the valve block.

[0009] In one embodiment, the thickness of the valve block of the combinable plunger-type multi-way valve is greater than the thickness of the actuator.

[0010] In one embodiment, the actuator of the combinable plunger-type multi-way distribution valve is a cylinder. The driving end of the cylinder is connected to a piston rod, the piston rod is connected to a connecting assembly, and the connecting assembly is connected to a plunger. The cylinder is used to drive the piston rod to move the plunger within the second through hole.

[0011] In one embodiment, the connection assembly of the combinable plunger-type multi-way valve includes a connecting column and two locking nuts, one end of the piston rod extending into the connecting column, one end of the plunger extending into the connecting column, and the two locking nuts respectively fixing the piston rod and the plunger in the connecting column.

[0012] In one embodiment, the valve block of the combinable plunger-type multi-way distribution valve is provided with a packing assembly for sealing and supporting the plunger in the second through hole. The packing assembly includes, in sequence, a packing gland, a packing sleeve, a first packing, a second packing, a third packing, a first packing ring, a fourth packing, a fifth packing, and a second packing ring. The inner wall of the packing sleeve is provided with a guide ring. The packing gland is connected to the valve block by a bolt assembly.

[0013] The beneficial effects of this application are as follows:

[0014] This application provides a combinable plunger-type multi-way distribution valve. This valve has multiple valve blocks on its body. The second through-holes of each valve block slide and engage with the plungers of multiple plunger valves. A third through-hole horizontally positioned on the side of each valve block communicates with the second through-hole for fluid inlet and outlet. A fourth through-hole horizontally positioned on one of the valve blocks communicates with the first through-hole for fluid inlet and outlet. By arranging openings on the sides of the multiple valve blocks, the valve body's inlet and outlet become side-inlet and side-outlet, enabling the plunger-type multi-way distribution valve to achieve one inlet and multiple outlets or multiple inlets and one outlet under high pressure. It also allows for the stacking of multiple multi-way distribution valves, significantly saving space.

[0015] The valve body of this plunger-type multi-way distribution valve not only has a simple structure, but also a shortened stroke, which greatly saves on operating costs.

[0016] The valve body of this plunger-type multi-way distribution valve is equipped with several positioning holes, which allow multiple multi-way distribution valves to be stacked together through the positioning holes, improving the stability of the stack and reducing the space occupied.

[0017] The thickness of the valve block of this plunger-type multi-way distribution valve is greater than the thickness of the actuator. Multiple multi-way distribution valves are stacked together with their valve bodies flat, which enhances the stability of the stacked multi-way distribution valves. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figures 1-3As shown, an embodiment of this application provides a combinable plunger-type multi-way distribution valve, including a plurality of multi-way distribution valves 1 stacked sequentially. The multi-way distribution valve 1 includes a valve body 11 and a plurality of plunger valves 12. The valve body 11 has a first through hole 111 inside. A plurality of valve blocks 112 for connecting one-to-one with the plurality of plunger valves 12 are horizontally arranged along the circumference of the first through hole 111. A second through hole 113 for moving the drive end of the plunger valve 12 is horizontally arranged inside the valve block 112. The second through hole 113 communicates with the first through hole 111. A third through hole 114 for communicating with the second through hole 113 is horizontally arranged on one side of each of the plurality of valve blocks 112. A fourth through hole 115 for communicating with the first through hole 111 is horizontally arranged on the other side of one of the valve blocks 112.

[0026] Specifically, four valve blocks 112 are arranged sequentially along the circumference of the first through hole 111 of the valve body 11, and the four valve blocks 112 are respectively connected to four plunger valves 12. The top and bottom surfaces of the valve blocks 112 are horizontal, and the valve blocks 112 also include a first side, a second side, and a third side arranged vertically. A second through hole 113 is provided inside the valve blocks 112. One end of the second through hole 113 communicates with the first through hole 111, and the other end of the second through hole 113 communicates with the second side. The plunger 123 of the plunger valve 12 extends into the second through hole 113 and slides within the second through hole 113. A third through hole 114 is provided on the first side of the valve block 112, which communicates with the second through hole 113. The third through hole 114 serves as either an inlet or outlet for the fluid. A fourth through hole 115 is provided on the second side of one of the four valve blocks 112, located to one side of the second through hole 113. The fourth through hole 115 communicates with the first through hole 111 and serves as either an outlet or inlet for the fluid. Multiple multi-way distribution valves 1 are connected and stacked sequentially via valve bodies 11.

[0027] When the four third through holes 114 are inlets and the fourth through hole 115 is an outlet, the actuators 121 of the four plunger valves 12 drive the plungers 123 to reciprocate within the second through hole 113. When the plunger 123 moves to open the third through hole 114, the fluid in the third through hole 114 flows into the second through hole 113 and is pushed into the first through hole 111 by the plunger 123. Then, it flows into the fourth through hole 115 from the first through hole 111 and finally flows out from the fourth through hole 115, thus realizing four inlets and one outlet under high pressure.

[0028] In the above structure, by optimizing the valve body 11 structure, not only is the stroke shortened and the operating space reduced, but the operating cost is also greatly saved. By arranging openings on the side ends of multiple valve blocks 112, the inlet and outlet of the valve body 11 become side-inlet and side-outlet, realizing one-inlet-multiple-outlet or multiple-inlet-one-outlet operation under high pressure. Furthermore, the planar design of the valve body 11 also allows for the stacking arrangement of multiple multi-way distribution valves 1, shortening pipeline connections and greatly saving overall installation space. This plunger 123 type multi-way distribution valve 1 not only realizes one-inlet-multiple-outlet or multiple-inlet-one-outlet operation under high pressure, but also enables the stacking and combination of multiple multi-way distribution valves 1, greatly saving operating space.

[0029] like Figure 2 and Figure 3 As shown, in one embodiment, the valve body 11 of the combinable plunger-type multi-way distribution valve is provided with a plurality of positioning holes 116. The positioning holes 116 are located outside the first through hole 111 and are not connected to the first through hole 111. The valve body 11 has four positioning holes 116. Two multi-way distribution valves 1 are stacked together, with the four positioning holes 116 on adjacent valve bodies 11 corresponding one-to-one, and then fixed by four positioning pins passing through the stacked positioning holes 116 in sequence. The provision of these positioning holes 116 improves the stability of stacking multiple multi-way distribution valves 1 and reduces the space occupied.

[0030] like Figure 2 As shown, in one embodiment, the number of valve blocks 112 in the combinable plunger-type multi-way distribution valve is four. Four second through holes 113 are provided on one side of each of the four valve blocks 112, and four third through holes 114 are provided on the other side of each of the four valve blocks 112. A fourth through hole 115 is provided on the side of one of the valve blocks 112. The four third through holes 114, four second through holes 113, one first through hole 111, and the first fourth through hole 115 cooperate to achieve one-in-four-out or four-in-one-out. This configuration enables the plunger-type multi-way distribution valve 1 to operate under high pressure with one-in-four-out or four-in-one-out operation.

[0031] like Figure 2As shown, in one embodiment, the plunger valve 12 of the combinable plunger-type multi-way distribution valve includes an actuator 121, a piston rod 122, and a plunger 123. The actuator 121 is connected to the valve block 112 via a column assembly 125. The drive end of the actuator 121 is connected to the piston rod 122, and the piston rod 122 is connected to the plunger 123 via a connecting assembly 124. The plunger 123 is slidably engaged with a second through hole 113 within the valve block 112. The drive end of the actuator 121 drives the piston rod 122 to move, the piston rod 122 pushes the connecting assembly 124 to move, and the connecting assembly 124 pushes the plunger 123 to reciprocate within the second through hole 113 of the valve block 112. This arrangement facilitates the reciprocating motion of the plunger 123 within the valve block 112, improving production efficiency.

[0032] like Figure 2 As shown, in one embodiment, the thickness of the valve block 112 of the combinable plunger-type multi-way valve is greater than the thickness of the actuator 121. The actuator 121 can be a cylinder; when a cylinder with greater thrust is required, two small-diameter cylinders connected in series can be used to reduce the thickness. Multiple multi-way valves 1 are stacked flatly together by the valve body 11, unaffected by the thickness of the actuator 121, thus enhancing the stability of the stacked multiple multi-way valves 1.

[0033] like Figure 2 As shown, in one embodiment, the actuator 121 of the combinable plunger-type multi-way distribution valve is a cylinder. The driving end of the cylinder is connected to the piston rod 122, the piston rod 122 is connected to the connecting assembly 124, and the connecting assembly 124 is connected to the plunger 123. The cylinder is used to drive the piston rod 122 to move the plunger 123 within the second through hole 113. This arrangement facilitates the reciprocating motion of the plunger 123 within the valve block 112.

[0034] like Figure 3 As shown, in one embodiment, the connecting assembly 124 of the combinable plunger-type multi-way distribution valve includes a connecting post 100 and two locking nuts 101. One end of the piston rod 122 extends into the connecting post 100, and one end of the plunger 123 extends into the connecting post 100. The two locking nuts 101 respectively fix the piston rod 122 and the plunger 123 within the connecting post 100. This arrangement secures the piston rod 122 and the plunger 123 on the connecting post 100, enhancing the reliability of the fixation and extending the service life.

[0035] like Figure 3 and Figure 4As shown, in one embodiment, the valve block 112 of the combinable plunger-type multi-way valve is provided with a packing assembly 117 for sealing and supporting the plunger 123 within the second through hole 113. The packing assembly 117 sequentially includes a packing gland 102, a packing sleeve 103, a first packing 104, a second packing 105, a third packing 106, a first packing ring 107, a fourth packing 108, a fifth packing 109, and a second packing ring 110. A guide ring 002 is provided on the inner wall of the packing sleeve 103. The packing gland 102 is connected to the valve block 112 via a bolt assembly 001. The packing gland 102 sequentially presses the packing sleeve 103, the first packing 104, the second packing 105, the third packing 106, the first packing ring 107, the fourth packing 108, the fifth packing 109, and the second packing ring 110 within the second through hole 113. This arrangement improves the sealing and support of the plunger 123.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
