Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a multifunctional regulating and shut-off valve group with an explosion-proof pressure gauge. Background Art

[0002] Mechanical equipment such as screw compressors involves numerous components requiring oil supply, including bearings, gears, rotors, and mechanical seals. Many pneumatic actuators also require instrument air. Therefore, branch lines must be drawn from the main oil or air supply line to the oil or air consumption points. The flow rate of each branch line must be regulated, and the pressure of each branch line must be monitored. This distributed oil or air supply system is widely used in industrial production sectors such as petroleum, chemical, machinery, and metallurgy.

[0003] In traditional distributed oil or gas supply applications, multiple two-way root valves are generally installed on the main pipeline to adjust the flow of oil or gas supply, and then the branch pipeline is led from the root valve to the required oil or gas supply point. However, when the pressure on the branch pipeline needs to be tested, another branch pipeline needs to be led out on the branch pipeline to install a pressure gauge. Not only is the pipeline complicated and the installation and maintenance workload large, but the large number of connection joints also means there are many leak-prone locations, which reduces reliability. Once a leak occurs, the main pipeline needs to be cut off for maintenance, affecting operational stability. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and to propose a multifunctional regulating and shut-off valve group with an explosion-proof pressure gauge.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multifunctional regulating and shut-off valve group with an explosion-proof pressure gauge includes a valve body, a connector threaded on the bottom of the valve body, support sleeves fixedly connected on both sides of the valve body, a valve stem threadedly inserted into the inner thread of the support sleeve, one end of the valve stem fixedly connected to a handle, and an end of the valve stem away from the handle fixedly connected to a cone head, a channel corresponding to the cone head is provided on the inner wall of the main body, a detection port is provided on the inner wall of one of the channels, and a pressure gauge is threadedly inserted into the detection port.

[0007] Preferably, a flow channel corresponding to the detection port is provided in one of the channels.

[0008] Preferably, the support sleeve is threadedly inserted into the valve body.

[0009] Preferably, an internal thread is provided around the top inner wall of the valve body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. All maintenance and operations of the shut-off valve in this utility model do not affect the fluid in the main pipeline. It can be used in distributed oil or gas supply. The configuration of two valves and a pressure gauge not only regulates the fluid flow in the branch pipeline, but also monitors the fluid medium pressure in the branch pipeline, thus effectively expanding the application range of the shut-off valve.

[0012] 2. The setting of the support sleeve in the utility model can facilitate the fixing and disassembly of the valve body and the valve stem, and the connecting head can facilitate the installation of the valve body on the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-2 A multifunctional regulating and shut-off valve group with an explosion-proof pressure gauge includes a valve body 2. An internal thread is provided around the inner wall of the valve body 2 at one end away from the main body 1. A connector 9 is threadedly sleeved on the bottom of the valve body 2. Support sleeves 3 are fixedly connected to both sides of the valve body 2. The support sleeves 3 are threadedly inserted into the valve body 2 to facilitate installation and removal of the support sleeves 3.

[0018] In this embodiment, the support sleeve 3 is internally threaded with a valve stem 4, which is used to drive the cone head 6 to move. One end of the valve stem 4 is fixedly connected to the handle 5, and the end of the valve stem 4 away from the handle 5 is fixedly connected to the cone head 6. The inner wall of the main body 1 is provided with a channel corresponding to the cone head 6 to control the fluid flow in the channel;

[0019] In this embodiment, a detection port 7 is provided on the inner wall of one of the channels for installing a pressure gauge 8. The pressure gauge 8 is inserted into the inner thread of the detection port 7. A flow channel 10 corresponding to the detection port is provided in one of the channels.

[0020] In this embodiment, the flow rate in the channel can be changed by rotating the handle 5, thereby adjusting the pressure of the fluid in the branch line and changing the flow rate of the branch line. The pressure gauge 8 can timely display the pressure in the branch line. The valve group can also completely cut off the fluid in the branch line, thus having both regulating and cutting functions.

[0021] In this embodiment, when the pressure gauge needs to be replaced or calibrated, the bottom handle 5 can be rotated to completely block the fluid; when the fluid or impurities in the branch pipe need to be discharged, the top handle 5 can be screwed shut, the pressure gauge 8 can be removed, and then the top handle 5 can be unscrewed for discharge.

[0022] In this embodiment, all maintenance and operations of the shut-off valve do not affect the fluid in the main pipeline; it can be used in the field of distributed oil or gas supply. Through the setting of two valves and a pressure gauge, not only the fluid flow of the branch pipeline can be adjusted, but also the fluid medium pressure of the branch pipeline can be monitored, thereby effectively improving the application scope of the shut-off valve.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
