Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a pressure-stabilizing valve device and a molecular catalytic type gas energy-saving and emission-reduction equipment. Background Art

[0002] A valve is a device used to control the flow of a medium. At present, with the continuous innovation of gas energy-saving and emission-reduction devices, by combining a physical device with molecular catalytic combustion assistance, the pressure inside the device is constantly changing; however, the traditional pressure-stabilizing valve has weak operability and low flexibility, and cannot be well matched with the new gas energy-saving and emission-reduction devices.

[0003] The pressure-stabilizing flow range of the traditional pressure-stabilizing valve structure is preset and cannot adjust the flow according to requirements. Therefore, when assembled on a molecular catalytic type gas energy-saving and emission-reduction equipment, if the pipeline pressure is too high, the catalyst will not have enough time to react; if the pipeline pressure is too low, the catalyst cannot be fully utilized. Thus, the traditional pressure-stabilizing valve structure is not well applicable to the molecular catalytic type gas energy-saving and emission-reduction equipment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a pressure-stabilizing valve and a molecular catalytic type gas energy-saving and emission-reduction equipment, which can adjust the flow quickly and conveniently, facilitate the pressure adjustment according to the catalyst requirements, and can be effectively applicable to the molecular catalytic type gas energy-saving and emission-reduction equipment.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a pressure-stabilizing valve device, including a housing shell, one side of the housing shell is provided with an intake pipe, the other side is provided with an outlet pipe, a communication hole is opened between the intake pipe and the outlet pipe, and a valve body is provided at the housing shell corresponding to the communication hole; the bottom of the valve body has a protruding pipe, an adjusting bolt is adjustably arranged in the protruding pipe, the tail of the adjusting bolt extends out of the protruding pipe, and a piston is fixed at the top, a spring is fixed at the top of the piston, and the other end of the spring is connected with a stop valve core, and the stop valve core cooperates with the communication hole to realize the on-off between the intake pipe and the outlet pipe; a valve disc is also hermetically connected between the outer circumferential wall of the stop valve core and the inner wall of the housing shell.

[0006] In the above solution, through the specific structural setting of the valve body, the distance between the stop valve core and the sealing surface of the communication hole can be adjusted by rotating the adjusting bolt as required, so as to achieve the purpose of adjusting the flow, thereby adjusting the medium output pressure and facilitating the expansion of the applicable range of the pressure-stabilizing valve device.

[0007] Preferably, an inlet joint is bolted to the outer shell corresponding to the intake end of the intake pipe. An intake passage is provided at the central position inside the inlet joint. An outlet joint is bolted to the outer shell corresponding to the outlet end of the outlet pipe. An outlet passage is provided at the central position inside the outlet joint. The inlet joint and the outer shell are sealed by a sealing gasket, and the outlet joint and the outer shell are also sealed by a sealing gasket. Through the design of the joints, it is convenient to provide effective intake and outlet passages for the valve device.

[0008] Furthermore, a threaded hole is provided on the side wall of the outer shell corresponding to the intake pipe, and a first connecting pipe is threadedly connected to the threaded hole. A threaded hole is also provided on the side wall of the outer shell corresponding to the outlet pipe, and a second connecting pipe is threadedly connected to the threaded hole. The first connecting pipe and the second connecting pipe are respectively connected to an external pressure gauge. Through the setting of the connecting pipes, it is convenient to externally connect a pressure gauge, facilitating the intuitive observation of the internal pressure of the valve device and facilitating the flow adjustment as needed.

[0009] Furthermore, the connection hole is adapted to the shape of the stop valve core. Specifically, a Y-shaped sealing ring is fixed to the inner wall of the connection hole, and the stop valve core has a conical structure adapted to the shape of the Y-shaped sealing ring.

[0010] A pressure stabilizing valve device adapted to a molecular catalytic type gas energy-saving and emission-reduction equipment includes a reaction chamber, a combustion chamber, and a slag removal chamber. The combustion chamber is connected to the top of the reaction chamber through a pipeline, and the slag removal chamber is connected to the bottom of the reaction chamber through a pipeline. One side of the reaction chamber is connected to a gaseous catalyst pipeline, and the other side is connected to a natural gas pipeline. The above-mentioned pressure stabilizing valve device is provided on both the gaseous catalyst pipeline and the natural gas pipeline.

[0011] The beneficial effects of the present invention are as follows: The pressure stabilizing valve device and the molecular catalytic type gas energy-saving and emission-reduction equipment provided by the present invention have a reasonable structural design and are effectively improved on the basis of the traditional pressure stabilizing valve structure, enabling the pressure stabilizing valve to adjust the flow rate through an adjusting bolt, thereby adjusting the output pressure of the gas medium. According to the quality of the catalyst in the catalyst tank on the combustion-supporting equipment, the air pressure of natural gas or gaseous catalyst introduced into the reaction tank per unit time by the pressure stabilizing valve structure can be adjusted, enabling the gas introduced into the reaction tank per unit time to react more fully with the gaseous low-temperature catalyst. This avoids the problems existing in the traditional pressure stabilizing valve structure, such as the pressure being too high to react with the catalyst in time and the pressure being too low to make full use of the catalyst.

[0016] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific implementation mode is not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0017] As Figure 1 shown, a pressure stabilizing valve device, the pressure stabilizing valve device 22 includes an outer shell housing 5 and a valve body 14.

[0018] One end of the outer shell housing 5 is installed with an inlet joint 1. An intake channel 2 is provided at the central position inside the inlet joint 1. An inlet pipe 4 is provided at a position inside the outer shell housing 5 close to one end of the inlet joint 1. An outlet pipe 8 is provided at a position inside the outer shell housing 5 close to the other end. An outlet joint 10 is installed at the other end of the outer shell housing 5. An outlet channel 11 is provided inside the outlet joint 10. A communication port is provided between the inlet pipe 4 and the outlet pipe 8, and a Y-shaped sealing ring 6 is installed on the inner wall of the communication port. The valve body 14 is fixedly installed at the bottom of the outer shell housing 5.

[0019] The bottom of the valve body 14 is provided with a protruding pipe. An adjusting bolt 17 is threadedly connected inside the protruding pipe. A piston 16 is fixedly installed inside the adjusting bolt 17. A spring 15 is fixedly connected to the upper part of the piston 16. The top end of the spring 15 is fixedly connected to a stop valve core 7, and a valve disc 13 is fixedly installed outside the stop valve core 7.

[0020] When the adjusting bolt 17 is rotated, the adjusting bolt 17 will move, thereby driving the spring 15 and the stop valve core 7 to move through the piston 16, and further adjusting the distance between the stop valve core 7 and the Y-shaped sealing ring 6 to achieve the purpose of adjusting the flow rate, thereby adjusting the pressure of the gaseous catalyst or natural gas.

[0021] In this embodiment, the shape of the shut-off valve core 7 is conical, and the shut-off valve core 7 is adaptively matched with the Y-shaped sealing ring 6.

[0022] When the shut-off valve core 7 coincides with the Y-shaped sealing ring 6, the communication port between the intake pipe 4 and the outlet pipe 8 can be blocked, thereby achieving the purpose of closing the valve.

[0023] A first connecting pipe 3 is fixedly installed near one end of the top of the outer shell 5, and a second connecting pipe 9 is fixedly installed near the other end of the outside of the outer shell 5. Threads are provided on the inner walls of both the first connecting pipe 3 and the second connecting pipe 9. The first connecting pipe 3 is communicated with the intake pipe 4, and the second connecting pipe 9 is communicated with the outlet pipe 8. The first connecting pipe 3 and the second connecting pipe 9 can be used to connect an external pressure gauge, so as to conveniently monitor the air pressure values in the intake pipe 4 and the outlet pipe 8.

[0024] On the basis of the above structure, the present invention also has a Figure 2 molecular catalytic type gas energy-saving and emission-reduction device as shown.

[0025] Specifically, the molecular catalytic type gas energy-saving and emission-reduction device includes a reaction chamber 23, a combustion chamber 18 and a slag removal chamber 20. The combustion chamber 18 is connected to the top of the reaction chamber 23 through a pipeline, and the slag removal chamber 20 is connected to the bottom of the reaction chamber 23 through a pipeline. A gaseous catalyst pipeline 21 is connected to one side of the reaction chamber 23, and a natural gas pipeline 19 is connected to the other side. The above-mentioned pressure stabilizing valve device 22 is provided on both the gaseous catalyst pipeline 21 and the natural gas pipeline 19.

[0026] In this embodiment, both between the inlet joint 1 and the outer shell 5 and between the outlet joint 10 and the outer shell 5 are connected by bolts, and sealing washers 12 are provided between the inlet joint 1 and the outer shell 5 and between the outlet joint 10 and the outer shell 5. The inlet joint 1 and the outlet joint 10 can conveniently connect the gaseous catalyst pipeline 21, the reaction chamber 23 and the natural gas pipeline 19 of the catalytic type gas energy-saving and emission-reduction device, and the sealing washer 12 can play a role in increasing the sealing performance.

[0027] During use, both pressure stabilizing valve devices 22 are respectively connected to the gaseous catalyst pipeline 21 and the reaction chamber 23 and between the natural gas pipeline 19 and the reaction chamber 23 through the inlet joint 1 and the outlet joint 10. During operation, the gaseous catalyst and natural gas respectively enter the outer shell 5 from the intake passage 2 through the gaseous catalyst pipeline 21 and the natural gas pipeline 19, then both enter the outlet pipe 8 through the Y-shaped sealing ring 6, and finally enter the reaction chamber 23 from the outlet joint 10 through the outlet passage 11, react in the reaction chamber 23 and then enter the combustion chamber 18 for combustion, and the waste residues generated by combustion are discharged into the slag removal chamber 20.

[0028] During the working process, the adjustable bolt 17 can be rotated to drive the piston 16 to move through the adjustable bolt 17, thereby driving the spring 15 and the stop valve core 7 to move, and further adjusting the distance between the stop valve core 7 and the Y-shaped sealing ring 6, so as to adjust the flow rate of the gaseous catalyst or natural gas, and dynamically adjust the air pressure of the gaseous catalyst and natural gas input into the reaction chamber 23, ensuring that natural gas can still fully react and burn in the later stage of using the catalyst, and further improving the energy-saving and emission-reduction effect of the device.

[0029] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
