Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulating of pressure reducing valves, in particular to a pressure regulating tool for pressure reducing valves. Background Art

[0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through regulation, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of reducing pressure. Then, by relying on the regulation of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range.

[0003] However, since the pressure reducing valve is in a high-pressure state during operation, the use of correct tooling can reduce the possibility of harm to workers from high-pressure gas or liquid during the process of adjusting the pressure of the pressure reducing valve; at the same time, the use of tooling can also ensure the accuracy of the adjustment results, so tooling should be used as much as possible when adjusting high-pressure valves.

[0004] For this purpose, we have proposed a new pressure reducing valve pressure regulating tooling. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a pressure regulating tool for a pressure reducing valve.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pressure regulating tool for a pressure reducing valve, comprising a pressure reducing valve nut threadedly connected to the top of a pressure reducing valve body and a jaw sleeved and abutted against the outer surface of the pressure reducing valve nut, a connecting plate fixedly connected to one side of the outer surface of the jaw, an L-shaped turning handle fixedly connected to one end of the connecting plate, a connecting seat sleeved and fixedly connected to the top of the L-shaped turning handle, a plug rod inserted through one end of the connecting seat, a nut fixedly connected to the lower surface of the plug rod, a pressure reducing valve knob abutted against the lower surface of the nut, and the pressure reducing valve knob fixedly installed on the top of the pressure reducing valve body.

[0007] Furthermore, the jaws are in a U-shaped structure, and the inner wall of the jaws matches the outer surface of the pressure reducing valve nut.

[0008] Furthermore, the side walls of the connecting seat are respectively provided with mounting holes matching the insertion rod and the L-shaped handle, and the insertion rod is slidably connected to the inner wall of the mounting hole, and the L-shaped handle is welded to the inner wall of the mounting hole, that is, the insertion rod and the connecting seat can move.

[0009] Furthermore, one end of the insertion rod is fixedly connected to a first handle, and the insertion rod can be lifted upward or pressed downward by holding the first handle.

[0010] Furthermore, a second handle is fixedly connected to one end of the L-shaped handle away from the connecting plate, and the presence of the handle makes it more convenient for the staff to grasp it.

[0011] Furthermore, the outer surfaces of the first handle and the second handle are both fixedly connected with anti-slip sleeves, and the anti-slip sleeves are made of rubber material.

[0012] Furthermore, an oblique brace is fixedly connected to the inner side of the bending part of the L-shaped handle, and the oblique brace and the bending part of the L-shaped handle together form a triangular structure, so that the structure of the L-shaped handle is more stable.

[0013] The utility model has the following beneficial effects:

[0014] When the utility model is in use, the pressure regulating tool for the pressure reducing valve, through the provided nut, the insert rod, the first handle, the L-shaped rotating handle, the connecting seat and the jaws, when adjusting the pressure of the pressure reducing valve body, only needs to align the jaws with the pressure reducing nut of the pressure reducing valve body, and after the entire device is installed in place, the insert rod is then inserted downward until the nut is pressed against the pressure reducing valve knob, and then the first handle is turned, so that the pressure reducing valve knob can be driven to rotate through the insert rod and the nut. Similarly, the pressure reducing valve nut can be tightened by only pushing the L-shaped rotating handle to make it do a circular motion around the top center of the pressure reducing valve body, which is safer, more reliable and more practical to use.

[0020] Figures 1 to 3As shown, it relates to a pressure regulating tool for a pressure reducing valve, including a pressure reducing valve nut 2 threadedly connected to the top of a pressure reducing valve body 1 and a jaw 12 sleeved and abutted against the outer surface of the pressure reducing valve nut 2, wherein the jaw 12 is a U-shaped structure, which is equivalent to the jaw structure of a wrench in the prior art, and the inner wall of the jaw 12 matches the outer surface of the pressure reducing valve nut 2, a connecting plate 11 is fixedly connected to one side of the outer surface of the jaw 12, an L-shaped turning handle 8 is fixedly connected to one end of the connecting plate 11, a connecting seat 7 is sleeved and fixedly connected to the top of the L-shaped turning handle 8, a plug rod 5 is inserted through one end of the connecting seat 7, a first handle 6 is fixedly connected to one end of the plug rod 5, a nut 4 is fixedly connected to the lower surface of the plug rod 5, a pressure reducing valve knob 3 is abutted against the lower surface of the nut 4, and the pressure reducing valve knob 3 is fixedly installed on the top of the pressure reducing valve body 1, wherein the nut 4 should be made of a material with greater friction, such as rubber, silicone, etc.

[0021] The side walls of the connecting seat 7 are respectively provided with mounting holes matching the insertion rod 5 and the L-shaped turning handle 8, and the insertion rod 5 is slidably connected to the inner wall of the mounting hole, and the L-shaped turning handle 8 is welded to the inner wall of the mounting hole, that is, the L-shaped turning handle 8 and the connecting seat 7 are fixed by welding, while the insertion rod 5 and the connecting seat 7 can be movable, and the insertion rod 5 can be lifted upward or pressed downward by holding the first handle 6.

[0022] The second handle 10 is fixedly connected to one end of the L-shaped handle 8 away from the connecting plate 11, and the outer surfaces of the first handle 6 and the second handle 10 are both fixedly connected with an anti-slip cover 13, and the anti-slip cover 13 is made of rubber material. The existence of the handle 10 can make it more convenient for the staff to grasp it, and the anti-slip cover 13 can increase the friction when in contact with the staff's hand to prevent slipping.

[0023] At the same time, the inner side of the bend of the L-shaped handle 8 is fixedly connected with a diagonal brace 9, and the diagonal brace 9 and the bend of the L-shaped handle 8 together form a triangular structure. The triangular structure is more stable and can make the L-shaped handle 8 have higher strength.

[0024] When using the pressure regulating tooling of the pressure reducing valve, first close the gate valve in front of the pressure reducing valve body 1, open the gate valve behind the pressure reducing valve, create a low-pressure environment downstream, rotate the pressure reducing valve knob 3 counterclockwise to the uppermost position (relative to the lowest outlet pressure), then close the gate valve behind the pressure reducing valve body 1, slowly open the gate valve in front of the pressure reducing valve body 1 to fully open, and then sleeve the jaws 12 on the outer surface of the pressure reducing valve nut 2, then hold the first handle 6, insert the rod 5 downward until the nut 4 is tightly against the pressure reducing valve knob 3, and then by turning the first handle 6, the pressure reducing valve knob 3 can be driven to rotate through the rod 5 and the nut 4, so that it rotates slowly clockwise to adjust the outlet pressure to the required pressure (based on the gauge pressure behind the valve). After adjustment, you can hold the handle 10 and push the L-shaped handle 8 to make it do a circular motion around the top center of the pressure reducing valve body 1, so that the pressure reducing valve nut 2 can be tightened, and the gate valve behind the pressure reducing valve can be opened to complete the pressure regulation process of the entire pressure reducing valve body 1. (If the outlet pressure is higher than the set pressure during adjustment, it is necessary to readjust from the first step, that is, it can only be adjusted from low pressure to high pressure.)

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
