Description

Technical Field

[0001] The utility model relates to the field of gas pressure regulators, in particular to a safe and explosion-proof gas pressure regulator. Background Art

[0002] A gas pressure regulator is a device used to regulate and control the flow of gas. It is usually used to regulate high-pressure gas from a bottled gas or pipeline system into the required low-pressure gas to ensure the safe and effective use of gas equipment and pipeline systems. Gas pressure regulators are widely used in various occasions such as industry, commerce, and households.

[0003] In the existing technology, although a certain gas pressure regulation process can be achieved during use, there are defects: the existing gas pressure regulators lack stable and simple explosion-proof measures, resulting in a lack of certain protective measures when gas leaks or deflagrates, directly causing serious safety accidents. In view of this, we have proposed a safe and explosion-proof gas pressure regulator to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a safe and explosion-proof gas pressure regulator for the problems existing in the background art.

[0005] The technical solution of the utility model: A safe and explosion-proof gas pressure regulator includes a pressure regulator body, an upper protective sleeve, and a lower protective sleeve. An upper protective sleeve is provided above the pressure regulator body, and a lower protective sleeve is provided below the pressure regulator body. The inner walls of the upper protective sleeve and the lower protective sleeve are provided with protrusions distributed in a honeycomb shape, and the inclination angle of the protrusions is sixty degrees;

[0006] When this device is in use, the specially customized upper protective sleeve is directly clamped on the upper end of the pressure regulator body, and then the lower protective sleeve is clamped from the lower end and fitted with the upper protective sleeve. Subsequently, multiple bolts are used in cooperation with installation blocks to fix the upper protective sleeve and the lower protective sleeve. When gas leaks or explodes, the air pressure value in the sealed space between the upper protective sleeve and the lower protective sleeve will be directly displayed on the upper end of the pressure gauge. And during an explosion, after the pressure gauge stabilizes, the source gas can be disconnected, and then the pressure relief valve can be repeatedly opened for treatment until the air pressure is stable before opening. Due to the protrusions designed on the inner walls of the upper protective sleeve and the lower protective sleeve, the concentrated explosion force can be dispersed by the inclined surface when the explosion shock wave is transmitted, reducing the explosion damage and achieving a stable explosion-proof effect.

[0007] Preferably, a notch is opened in the middle of one side of the upper protective sleeve, and the bottom of the notch is semi-circular. A limiting plate is fixed on one side of the lower protective sleeve, the top of the limiting plate is semi-circular, the diameter of the semi-circular area on one side of the limiting plate is equal to the diameter of the semi-circular area inside the upper protective sleeve, and is equal to the diameter of the cylinder on one side of the pressure regulator body.

[0008] Preferably, a limiting groove and a limiting key are designed at the insertion part between the upper protective cover and the lower protective cover. The limiting groove is opened on the inner wall of the upper protective cover, and the limiting key is located on the outer wall of the limiting plate.

[0009] Preferably, mounting blocks are fixed on the outer walls of one side of the upper protective cover and the lower protective cover. The mounting blocks are fixedly connected by bolts, and a sealing gasket is adhered to the opposite surfaces of the lower protective cover and the upper protective cover.

[0010] Preferably, flange plates are provided on both sides of the pressure regulator body. Sealing rings are fixed on the surfaces of the flange plates. A pressure regulating nut is rotatably installed on one side of the pressure regulator body, and a locking nut is rotatably installed on one side of the pressure regulating nut.

[0011] Preferably, a first groove is symmetrically opened on the outer walls of both sides of the upper protective cover, and a second groove is symmetrically opened on both sides of the lower protective cover. The diameters of the first groove and the second groove are equal.

[0012] Preferably, a pressure gauge is installed and fixed at the upper end of the upper protective cover, and a pressure relief valve is embedded and installed on the outer wall of one side of the upper protective cover.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] First, the present utility model can directly seal and protect the periphery of the pressure regulator body by using the upper protective cover and the lower protective cover that can be quickly disassembled and assembled, and the connection part is well sealed, so that large-scale disasters will not be caused when leakage or explosion occurs inside.

[0015] Second, based on the first beneficial effect, when an explosion occurs, the air wave will directly act on the protrusion, and the inclined surfaces on both sides of the protrusion will disperse the impact force, reducing the single-point impact force to damage it, and having a high-strength explosion-proof effect.

[0016] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 1

[0030] Please refer to Figures 1-6 As shown, this embodiment is a safe and explosion-proof gas pressure regulator, including a pressure regulator body 1, an upper protective sleeve 5 and a lower protective sleeve 9. An upper protective sleeve 5 is provided above the pressure regulator body 1, and a lower protective sleeve 9 is provided below the pressure regulator body 1. The inner walls of the upper protective sleeve 5 and the lower protective sleeve 9 are provided with protrusions 15 distributed in a honeycomb pattern, and the inclination angle of the protrusions 15 is sixty degrees. The materials of the upper protective sleeve 5 and the lower protective sleeve 9 are both steel materials, having a high-strength protection effect;

[0031] When this device is in use, directly snap the specially customized upper protective cover 5 onto the upper end of the pressure regulator body 1. Then, snap the lower protective cover 9 onto the lower end and fit it with the upper protective cover 5. Subsequently, use multiple bolts 14 and the mounting blocks 7 to fix the upper protective cover 5 and the lower protective cover 9 together. When gas leakage or explosion occurs, the air pressure value in the sealed space between the upper protective cover 5 and the lower protective cover 9 will be directly displayed on the upper end of the pressure gauge 4. And during an explosion, after the pressure gauge 4 stabilizes, the source gas can be disconnected, and then the pressure relief valve 3 can be repeatedly opened for treatment until the pressure is stable before opening. Due to the protrusions 15 designed on the inner walls of the upper protective cover 5 and the lower protective cover 9, when the explosion shock wave is transmitted, the concentrated explosion force can be dispersed using the inclined plane, reducing the explosion damage and achieving a stable explosion-proof effect.

[0032] A notch is provided in the middle of one side of the upper protective cover 5, and the bottom of the notch is semi-circular. A limiting plate 13 is fixed on one side of the lower protective cover 9. The top of the limiting plate 13 is semi-circular. The diameter of the semi-circular area on one side of the limiting plate 13 is equal to the diameter of the semi-circular area inside the upper protective cover 5 and is also equal to the diameter of the cylinder on one side of the pressure regulator body 1. The upper protective cover 5 and the lower protective cover 9 are inserted up and down to form a sealed space, achieving sealing and providing effective protection.

[0036] Flange plates 12 are provided on both sides of the pressure regulator body 1. Sealing rings 11 are fixed on the surfaces of the flange plates 12. A pressure regulating nut 16 is rotatably installed on one side of the pressure regulator body 1, and a locking nut 8 is rotatably installed on one side of the pressure regulating nut 16. The structures provided here all belong to the conventional structures of the pressure regulator body 1. The internal design of the pressure regulator body 1 and the working mode of the structure will not be described in detail, which belongs to the common device types in the industry.

[0037] On both outer walls of the upper protective sleeve 5, symmetrically arranged are the first grooves 2. On both sides of the lower protective sleeve 9, symmetrically arranged are the second grooves 10. The first grooves 2 and the second grooves 10 have the same diameter. After the first grooves 2 and the second grooves 10 are fitted together, they can just straddle the pipe bodies on both sides of the flange 12 to achieve a sealing effect.

[0038] At the upper end of the upper protective sleeve 5, a pressure gauge 4 is fixedly installed. On one outer wall of the upper protective sleeve 5, a pressure relief valve 3 is embedded and installed. The pressure gauge 4 can detect the air pressure inside the sealed area, and the pressure relief valve 3 can be intermittently opened by the rear-end control system to achieve the stability of regulating the air pressure after internal leakage or deflagration.
