Description

Technical Field

[0001] This utility model relates to the field of valve block technology, and in particular to a heat-resistant and explosion-proof three-way valve block. Background Technology

[0002] Existing heat-resistant and explosion-proof three-way valve blocks typically involve mounting multiple valves on a single, relatively large block. This reduces the number of pipe connections, lowers the risk of leakage, and improves system reliability. However, the large size and weight of the valve blocks make them unsuitable for space-constrained applications. Furthermore, the complex internal structure of the valve blocks necessitates disassembling the entire block during maintenance, which is cumbersome and time-consuming. While a single bolt can connect multiple valve blocks, solving the problem of large individual block size, maintenance still requires disassembling all blocks. Additionally, an excessive number of valve blocks can reduce the bolt's connection effectiveness, leading to unstable connections and limiting their applicability. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a heat-resistant and explosion-proof three-way valve block. It uses stainless steel, which has the effects of impact resistance, high temperature resistance and corrosion resistance, as the material of the valve block, so that the valve block has good heat resistance and explosion-proof properties. By inserting the insert plate on one set of valve blocks into the slot on another set of valve blocks and fixing it with bolts, the two sets of valve blocks can be fixed together, reducing the number of pipeline connections, thereby reducing the risk of leakage and making the valve blocks easy to maintain. At the same time, the connecting pipe is used to drive the insert pipe to be fixed into the communication port, which enhances the connection effect. And a set of sealing rings with a diameter larger than the insert pipe is used to further improve the sealing performance at the connection between the two sets of valve blocks.

[0004] This utility model also provides a heat-resistant and explosion-proof three-way valve block, comprising: a valve block body, a main channel provided inside the valve block body, a through groove provided on the side surface of the valve block body, a connecting port provided on the side surface of the valve block body, a connecting pipe threadedly connected to the side surface of the valve block body, and an insertion tube fixedly connected to the end of the connecting pipe away from the valve block body.

[0005] A rotating plate is rotatably connected to the side surface of the valve block, and an insert plate is fixedly connected to the side surface of the rotating plate. The side surface of the valve block has a slot and a fixing groove, and a bolt is threaded onto its side surface. These components allow multiple valve blocks to be combined by inserting the insert plate into the slots of adjacent valve blocks and securing it with bolts, thus solving the problem of large size and difficulty in disassembling and maintaining a single valve block.

[0006] According to the heat-resistant and explosion-proof three-way valve block of this utility model, a second sealing ring is fixedly connected to the side surface of the connecting pipe, and the second sealing ring is located between the connecting pipe and the valve block body. The second sealing ring between the connecting pipe and the valve block body enhances the sealing effect at the connection point.

[0007] According to the heat-resistant and explosion-proof three-way valve block of this utility model, a sealing ring is fixedly connected to the side surface of the connecting pipe. The sealing ring is located between the connecting pipe and the insert pipe, and the diameter of the sealing ring is larger than the diameter of the insert pipe. When the insert pipe is inserted into the connecting port of another set of valve block bodies, the sealing ring is positioned between the insert pipe and the valve block body, thereby enhancing the sealing effect.

[0008] According to the heat-resistant and explosion-proof three-way valve block of this utility model, the through groove is provided with an internal thread, and the through groove is connected to the main channel. This allows the valve to be fixed to the valve block body by the internal thread, and allows the valve to be connected to the main pipeline through the through groove.

[0009] According to the heat-resistant and explosion-proof three-way valve block of this utility model, the fixing groove is connected to the slot, and the side surface of the valve block is provided with a placement groove. The rotating plate and the insert plate are located inside the placement groove during operation. When not in use, the rotating plate and the insert plate are retracted into the placement groove so as not to affect the use of the valve block.

[0010] According to the heat-resistant and explosion-proof three-way valve block of this utility model, a limiting block is fixedly connected to the side surface of the valve block body, and the side surface of the limiting block is fixedly connected to the insert plate during operation. When the rotating plate and the insert plate are retracted into the placement groove, the limiting block limits the insert plate, preventing it from easily detaching from the placement groove.

[0011] According to the heat-resistant and explosion-proof three-way valve block of this utility model, the side surface of the insert plate is provided with a fixing hole, and the end of the insert plate away from the rotating plate extends into the slot of another valve block body during operation. This allows bolts to fix the insert plate inside the other valve block body through the fixing hole.

[0012] According to the heat-resistant and explosion-proof three-way valve block of this utility model, the bolt, at one end near the valve block body, extends through the fixing hole into the fixing groove during operation, and the side surface of the bolt is fixedly connected to the insert plate during operation. The bolt is used to fix the insert plate inserted into the slot, thereby achieving the function of fixing two sets of valve blocks together.

[0013] Beneficial effects:

[0014] Compared with existing technologies, stainless steel, which is impact-resistant, high-temperature resistant, and corrosion-resistant, is used as the material for the valve block, giving it excellent heat resistance and explosion-proof properties. By inserting the insert plate on one set of valve blocks into the slot on another set of valve blocks and fixing it with bolts, adjacent sets of valve blocks can be fixed together, reducing pipeline connections and thus lowering the risk of leakage. This makes the valve blocks easier to maintain. At the same time, the connecting pipe is used to drive the insert pipe into the communication port, enhancing the connection effect. A set of sealing rings with a diameter larger than the insert pipe is used to further improve the sealing performance at the connection between the two sets of valve blocks.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-6The present invention relates to a heat-resistant and explosion-proof three-way valve block, comprising: a valve block body 1, a main channel 16 provided inside the valve block body 1, a through groove 17 provided on the side surface of the valve block body 1, an internal thread 2 provided in the through groove 17, the through groove 17 being connected to the main channel 16, a connecting port 14 provided on the side surface of the valve block body 1, a connecting pipe 6 threadedly connected to the side surface of the valve block body 1, a sealing ring 2 15 fixedly connected to the side surface of the connecting pipe 6, the sealing ring 2 15 being located between the connecting pipe 6 and the valve block body 1, an insertion pipe 8 fixedly connected to the end of the connecting pipe 6 away from the valve block body 1, a sealing ring 1 7 fixedly connected to the side surface of the connecting pipe 6, the sealing ring 1 7 being located between the connecting pipe 6 and the insertion pipe 8, and the diameter of the sealing ring 1 7 being larger than the diameter of the insertion pipe 8;

[0026] Specifically, the valve block 1 is made of stainless steel, which has the effects of impact resistance, high temperature resistance, and corrosion resistance, giving the valve block 1 good heat resistance and explosion-proof performance. The valve block 1 has a main channel 16 inside, and a set of through grooves 17 on each of the three surfaces. Each through groove 17 has an internal thread 2 for connecting the valve. The two ends of the main channel 16 are respectively provided with a connecting port 14 and a connecting pipe 6. One end of the connecting pipe 6 is connected to a plug 8. A second sealing ring 15 and a first sealing ring 7 are respectively provided between the connecting pipe 6, the valve block 1, and the plug 8. During use, the connecting pipe 6 of one set of valve blocks 1 can be inserted into the connecting port 14 of another set of valve blocks 1, so that the two sets of valve blocks 1 can be connected together. Since the diameter of the first sealing ring 7 is larger than that of the plug 8, the first sealing ring 7 can play a good sealing role when the two sets of valve blocks 1 are connected together.

[0027] A rotating plate 10 is rotatably connected to the side surface of the valve block 1. An insert plate 11 is fixedly connected to the side surface of the rotating plate 10. A fixing hole 12 is provided on the side surface of the insert plate 11. The end of the insert plate 11 away from the rotating plate 10 extends into the slot 3 of another set of valve block 1 during operation. A slot 3 is provided on the side surface of the valve block 1. A fixing groove 4 is provided on the side surface of the valve block 1. A bolt 5 is threadedly connected to the side surface of the valve block 1. The end of the bolt 5 near the valve block 1 extends through the fixing hole 12 into the fixing groove 4 during operation. The side surface of the bolt 5 is fixedly connected to the insert plate 11 during operation.

[0028] Specifically, when connecting the two sets of valve block 1, the insert plate 11 and the rotating plate 10 can be moved first to disengage the insert plate 11 from the placement groove 9. Then, each insert plate 11 is inserted into the corresponding slot 3 of the other valve block 1. After that, the bolt 5 is inserted into the fixing groove 4 and the bolt 5 passes through the fixing hole 12 on the insert plate 11 and is fixed inside the valve block 1. At the same time, the insert plate 11 can also be completely fixed in the slot 3, so that the two sets of valve block 1 are fixed together.

[0029] The fixed groove 4 is connected to the slot 3. The side surface of the valve block 1 is provided with a placement groove 9. The rotating plate 10 and the insert plate 11 are located inside the placement groove 9 during operation. The side surface of the valve block 1 is fixedly connected to the limiting block 13. The side surface of the limiting block 13 is fixedly connected to the insert plate 11 during operation.

[0030] Specifically, the surface of the valve block 1 is provided with a placement groove 9, and a limiting block 13 is fixed at the position of the valve block 1 in the placement groove 9. Under normal circumstances, the rotating plate 10 and the insert plate 11 can be put into the placement groove 9 and restricted by the limiting block 13, so that the rotating plate 10 and the insert plate 11 are not easy to get out of the placement groove 9 and thus affect the normal use of the valve block 1. When it is necessary to connect two sets of valve blocks 1, the insert plate 11 can be pulled through the fixing hole 12 on the insert plate 11 to make the insert plate 11 get out of the fixation of the limiting block 13.

[0031] Working principle: During use, the valve can be installed on the valve block 1 through the internal thread 2, and the valve is connected to the main channel 16 through the through groove 17. When it is necessary to connect two sets of valve blocks 1 together, first install the connecting pipe 6 on the valve block 1, then move the insert plate 11 and the rotating plate 10 on the other set of valve blocks 1 to make the insert plate 11 disengage from the placement groove 9, and then insert each insert plate 11 into the corresponding slot 3 of the valve block 1. At the same time, the connecting pipe 6 can drive the insert pipe 8 to be inserted into the communication port 14 of the other set of valve blocks 1. When the two sets of valve blocks 1 are completely fitted, insert the bolt 5 into the fixing groove 4, and make the bolt 5 pass through the fixing hole 12 on the insert plate 11 to fix it inside the valve block 1. At the same time, the insert plate 11 can also be completely fixed in the slot 3, so that the two sets of valve blocks 1 are fixed together.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
