Description

Technical Field

[0001] The invention belongs to the technical field of valves, and in particular relates to a small-space gas coil piping structure. Background Art

[0002] A valve is a control component in a fluid delivery system, which has the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems are used in everything from the simplest shutoff valve to the most complex automatic control system. The existing valve system uses parallel valve technology to control the four flow effects of liquids. This method takes up a lot of space and has poor practicality. This phenomenon has become a problem that needs to be solved urgently by people in this field. Summary of the invention

[0003] The purpose of the present invention is to provide a small-space gas coil piping structure for existing skidding equipment to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a small space gas coil piping structure, comprising valve layer one and valve layer two, wherein the bottom of the valve layer one is fixedly installed with an intermediate layer one by bolts, and the bottom of the valve layer two is fixedly installed with an intermediate layer two by bolts, the valve layer one is a three-port valve, and the valve layer two is a two-port valve, which can be easily assembled through the assembled valve block setting, and the modular assembly form is more convenient for maintenance.

[0005] The present invention further illustrates that the valve layer 1 is provided with a flow channel 1 and a flow channel 2, the flow channel 1 and the flow channel 2 are interconnected, the flow channel 1 and the flow channel 2 are both connected through a normally closed pneumatic or electric diaphragm valve 1, the bottom of the normally closed pneumatic or electric diaphragm valve 1 is provided with a throttle hole 1, the valve layer 2 is provided with a flow channel 3 and a flow channel 4, one end of the flow channel 3 is provided with a throttle hole 2, the flow channel 3 and the flow channel 4 are connected through a normally closed pneumatic or electric diaphragm valve 2, The normally closed pneumatic or electric diaphragm valve 1 and the normally closed pneumatic or electric diaphragm valve 2 are controlled by external pneumatic or electric control. When the normally closed pneumatic or electric diaphragm valve 1 and the normally closed pneumatic or electric diaphragm valve 2 are both closed, all flow channels are closed. When the normally closed pneumatic or electric diaphragm valve 1 is opened, the flow can flow down from the throttle hole 1. When the normally closed pneumatic or electric diaphragm valve 2 is opened, the flow can flow down from the throttle hole 2. When both are opened, the flow is maximum, which facilitates the realization of four forms of flow control.

[0006] The present invention is further described as follows. Inside the first intermediate layer, a fifth flow channel, a sixth flow channel, and a seventh flow channel are respectively provided. The top end of the fifth flow channel communicates with the first flow channel, the top end of the sixth flow channel communicates with the first throttle hole, one end of the seventh flow channel communicates with the second flow channel, and the other end of the seventh flow channel communicates with the third flow channel. When in use, first, the air flow introduced is received in the fifth flow channel, and the air flow discharged from the first throttle hole is received in the sixth flow channel. The first intermediate layer is communicated with the second valve layer through the seventh flow channel, realizing various flow rate controls.

[0007] The present invention is further described as follows. Inside the second intermediate layer, an eighth flow channel and a ninth flow channel are provided. The top end of the eighth flow channel communicates with the fourth flow channel, and the eighth flow channel communicates with the ninth flow channel. The output flow channels are communicated through the second intermediate layer, enabling the air flow to still flow out from the outlet when the normally closed pneumatic or electric diaphragm valve two is closed.

[0008] The present invention is further described as follows. At the bottoms of the first intermediate layer and the second intermediate layer, a tenth flow channel, an eleventh flow channel, and a twelfth flow channel are respectively provided in a penetrating manner. The top end of the tenth flow channel communicates with the fifth flow channel, both ends of the eleventh flow channel communicate with the sixth flow channel and the eighth flow channel respectively, and the top end of the twelfth flow channel communicates with the ninth flow channel. The above-mentioned various flow channels are integrated through pipelines, facilitating the output of the flow rate.

[0009] The present invention is further described as follows. One end of the tenth flow channel communicates with an external pipeline, and one end of the twelfth flow channel communicates with an external pipeline on the other side. When in use, liquid is introduced from the left end and flows out from the right end, which can conveniently achieve single - outlet control.

[0010] The present invention is further described as follows. The first intermediate layer and the second intermediate layer are joined together, and the joint surface is two mutually overlapping L - shapes. The upper half of the first intermediate layer protrudes outward on the contact surface, and the lower half of the second intermediate layer protrudes outward on the contact surface. Due to the mutual stagger of this joining method, a relatively large reaction force can be provided when a vertically downward force is applied.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The advantage of the present invention is that it only occupies one - unit width, greatly saving space when used in multiple channels. Moreover, the valve blocks are installed in a combined manner. When replacement is needed, only the problematic part needs to be removed for repair or directly replaced, greatly saving the cost of fault repair. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiments

[0019] The following further describes the technical solution of the present invention in detail and non - restrictively in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a pipeline structure of a small - space air circuit panel, including Valve Layer 1 (1) and Valve Layer 2 (2). The bottom of Valve Layer 1 (1) is fixedly installed with Intermediate Layer 1 (3) by bolts, and the bottom of Valve Layer 2 (2) is fixedly installed with Intermediate Layer 2 (4) by bolts. Valve Layer 1 (1) is a three - port valve, and Valve Layer 2 (2) is a two - port valve. Through the setting of assembled valve blocks, it is convenient for splicing, and the modular assembly form is more convenient for maintenance;

[0021] Inside the valve layer 1, a first flow channel 11 and a second flow channel 13 are provided. The first flow channel 11 and the second flow channel 13 communicate with each other. Both the first flow channel 11 and the second flow channel 13 are connected to a normally closed pneumatic or electric diaphragm valve 14 in a through manner. At the bottom of the normally closed pneumatic or electric diaphragm valve 14, a first throttle hole 12 is provided in a through manner. Inside the valve layer 2, a third flow channel 21 and a fourth flow channel 22 are provided. At one end of the third flow channel 21, a second throttle hole 24 is provided in a through manner. A normally closed pneumatic or electric diaphragm valve 23 is connected between the third flow channel 21 and the fourth flow channel 22 in a through manner. The normally closed pneumatic or electric diaphragm valve 14 and the normally closed pneumatic or electric diaphragm valve 23 are controlled by external pneumatic or electric means to change the switch state. When both the normally closed pneumatic or electric diaphragm valve 14 and the normally closed pneumatic or electric diaphragm valve 23 are closed, all the flow channels are closed at this time. When the normally closed pneumatic or electric diaphragm valve 14 is opened, the flow can flow down from the first throttle hole 12. When the normally closed pneumatic or electric diaphragm valve 23 is opened, the flow can flow down from the second throttle hole 24. When both are opened, the flow is the largest, which is convenient to achieve four forms of flow control;

[0022] Inside the first intermediate layer 3, a fifth flow channel 31, a sixth flow channel 32 and a seventh flow channel 33 are respectively provided. The top end of the fifth flow channel 31 communicates with the first flow channel 11. The top end of the sixth flow channel 32 communicates with the first throttle hole 12. One end of the seventh flow channel 33 communicates with the second flow channel 13. One end of the seventh flow channel 33 communicates with the third flow channel 21. When in use, first, the incoming air flow is received in the fifth flow channel 31, and the air flow discharged from the first throttle hole 12 is received in the sixth flow channel 32. The first intermediate layer 3 is connected to the valve layer 2 through the seventh flow channel 33 to achieve multiple controls of the flow;

[0023] Inside the second intermediate layer 4, an eighth flow channel 34 and a ninth flow channel 35 are provided. The top end of the eighth flow channel 34 communicates with the fourth flow channel 22. The eighth flow channel 34 communicates with the ninth flow channel 35. The output flow channels are connected through the second intermediate layer 4 to ensure that the air flow can still flow out from the outlet when the normally closed pneumatic or electric diaphragm valve 23 is closed;

[0024] At the bottom of the first intermediate layer 3 and the second intermediate layer 4, a tenth flow channel 51, an eleventh flow channel 52 and a twelfth flow channel 53 are respectively provided in a through manner. The top end of the tenth flow channel 51 communicates with the fifth flow channel 31. Both ends of the eleventh flow channel 52 communicate with the sixth flow channel 32 and the eighth flow channel 34 respectively. The top end of the twelfth flow channel 53 communicates with the ninth flow channel 35. The above flow channels are integrated through pipelines to facilitate the output of the flow;

[0025] One end of the tenth flow channel 51 communicates with an external pipeline. One end of the twelfth flow channel 53 communicates with another external pipeline. When in use, liquid is introduced from the left end and gas flows out from the right end, which can conveniently achieve single - outlet control;

[0026] The advantages are that it only occupies one-bit width, greatly saving space when used multiplexly, and the valve blocks are assembled in a combined manner. When replacement is needed, only the problematic part needs to be removed for repair or directly replaced, greatly saving the cost of fault repair;

[0027] The middle layer 3 and the middle layer 4 are joined together, and the joint surface is two mutually overlapping L-shapes. The middle layer 3 protrudes outward in the upper half of the contact surface, and the middle layer 4 protrudes outward in the lower half of the contact surface. Due to the mutual stagger of this joining method, a large reaction force can be provided when a vertically downward force is applied;

[0028] Comparative Example 1: As Figure 5 , as the original scheme of this solution, the flow channel 11 and the flow channel 21 communicate with each other. The valve layer 1 and the valve layer 2 are separately and independently arranged. The throttle hole 12 and the throttle hole 24 communicate with each other. The flow channel 11 communicates with the outer wall of the valve layer 1. This scheme is for connecting and controlling two valve bodies and also has an output port. The difference is that the horizontal occupied space is larger, while the vertical occupied space is smaller, and it is suitable for different usage occasions.

[0029] Example 1: The throttle hole 12 and the throttle hole 24 are intercepted in the following forms:

[0030] a. Gasket type; b. Embedded in the valve; c. Embedded in the middle layer flow block; Good sealing performance, convenient for replacing different-sized flow-limiting holes to achieve different flow ratios. The flexibility is reduced. To replace the size of the flow-limiting hole, the valve needs to be replaced.
