Description

Technical Field

[0001] The utility model relates to a valve replacement device and belongs to the technical field of valve replacement devices. Background Art

[0002] Valve replacement usually refers to the process of replacing or updating the original valves (such as control valves, stop valves, etc.) in industrial equipment or pipeline systems. Valves play an important role in controlling fluid flow, regulating pressure and closing fluid flow in pipeline systems.

[0003] The Chinese patent number CN217061696U is a transformer valve replacement device, comprising: an airbag, one end of which is connected to an airbag rod, which is used to assist in adjusting the expansion degree of the airbag; a transition chamber, one end of which is provided with a valve connection structure, and the airbag is used as a plugging device to achieve rapid plugging, disassembly and replacement, saving time and effort. The transition chamber and the airbag are used in conjunction, so that the airbag has good contact with the valve to be replaced, which is easy to operate, simple in structure, high in reliability and low in cost, and can be used repeatedly.

[0004] When the strip pipeline is disassembled without stopping operation, some dangerous gases will still remain in the strip pipeline. Once there is a flammable risk in the working environment, dangerous accidents may occur, which is not conducive to ensuring the replacement and installation efficiency of the valve body outside the strip pipeline. Therefore, it is necessary to design a safer valve replacement device to solve the above problems.

[0005] To this end, a valve replacement device is proposed. Utility Model Content

[0006] In view of this, the utility model provides a valve replacement device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the utility model is achieved as follows: a valve replacement device comprises a strip pipe installed on the side of a valve body, the upper end of the strip pipe is fixedly connected to a gate valve installer, the upper end of the gate valve installer is fixedly connected to a balloon blocker, the inner end of the balloon blocker is installed with a partition airbag, the inner end of the partition airbag is fixedly connected to a ball storage balloon, the upper end of the ball storage balloon is fixedly connected to an air intake hose, the upper end of the air intake hose is fixedly connected to an air intake check valve, the left and right ends of the ball storage balloon are symmetrically fixedly connected to air outlet hoses, and the end of the air outlet hose away from the ball storage balloon is fixedly connected to the air outlet check valve.

[0008] Further preferably, the two air outlet one-way valves are respectively located on the left and right sides of the partition airbag, and the air inlet one-way valve is located on the upper side of the partition airbag.

[0009] Further preferably, the partition airbag extends into the strip-shaped pipe, and the right end of the balloon blocker is fixedly connected to an airflow output pipe opening.

[0010] Further preferably, the outer end of the air storage balloon is covered with a spherical shell, and the air inlet hose and the two air outlet hoses all pass through the inside and outside of the spherical shell.

[0011] Further preferably, the four corners of the inner end of the spherical shell are fixedly connected with contact sensors, and the contact sensors cooperate with the outer side wall of the ball storage balloon.

[0012] Further preferably, the inner end of the gas storage balloon is filled with flame-retardant gas, and the partition balloon is externally connected to a pump.

[0013] Further preferably, left and right sides of the outer end of the partition airbag are fixedly connected with side reinforcing ribs, and the side reinforcing ribs are in contact with the inner side wall of the strip pipe.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. In this scheme, a gas storage balloon is filled in the partition airbag, and flame-retardant gas is filled in the balloon using an air intake hose. After the partition airbag penetrates into the strip pipe and is inflated, an external control terminal can be used to open the gas outlet one-way valve to gradually discharge the flame-retardant gas in the gas storage balloon, so that the area near the valve body in the strip pipe is filled with flame-retardant gas, thereby reducing the oxygen concentration in the strip pipe and the probability of dangerous accidents, which is beneficial to ensuring the safety of the replacement and disassembly process of the valve body outside the strip pipe.

[0016] Second, a spherical shell can be set on the outside of the air storage balloon, and multiple contact sensors can be set inside the spherical shell. When the air storage balloon is filled with flame-retardant gas using an external pump, the air storage balloon can gradually fit with the contact sensor during the expansion process, so that the inflation degree can be clearly controlled, avoiding the disadvantage of insufficient flame-retardant gas distribution efficiency caused by insufficient filling degree in the air storage balloon, which is beneficial to ensuring the gas filling efficiency of the air storage balloon.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, an embodiment of the utility model provides a valve replacement device, including a strip pipe 1 installed on the side of a valve body 2, the upper end of the strip pipe 1 is fixedly connected with a gate valve installer 11, the upper end of the gate valve installer 11 is fixedly connected with a balloon blocker 4, the inner end of the balloon blocker 4 is installed with a partition airbag 3, the inner end of the partition airbag 3 is fixedly connected with a ball storage balloon 13, the upper end of the ball storage balloon 13 is fixedly connected with an air intake hose 7, the upper end of the air intake hose 7 is fixedly connected with an air intake check valve 8, the left and right ends of the ball storage balloon 13 are symmetrically fixedly connected with an air outlet hose 6, and the end of the air outlet hose 6 away from the ball storage balloon 13 is fixedly connected with an air outlet check valve 9.

[0028] Two air outlet one-way valves 9 are respectively located on the left and right sides of the partition airbag 3, and the air inlet one-way valve 8 is located on the upper side of the partition airbag 3. The partition airbag 3 extends into the strip pipe 1. The right end of the balloon blocker 4 is fixedly connected to the airflow output pipe port 10. The partition airbag 3 is externally connected to a pump machine. The left and right sides of the outer end of the partition airbag 3 are fixedly connected to side reinforcement ribs 12, and the side reinforcement ribs 12 are in contact with the inner wall of the strip pipe 1.

[0029] Example 2

[0030] In one embodiment, the outer end of the air storage balloon 13 is covered with a spherical shell 5, the air inlet hose 7 and the two air outlet hoses 6 pass through the spherical shell 5, and the four corners of the inner end of the spherical shell 5 are fixedly connected with contact sensors 14.

[0031] The inner end of the air storage balloon 13 is filled with flame-retardant gas through the cooperation between the contact sensor 14 and the outer side wall of the air storage balloon 13 .

[0032] When the utility model is in operation: before replacing and disassembling the valve body 2 outside the strip pipe 1, the gate valve installer 11 can be installed on the strip pipe 1 to cooperate with the balloon blocker 4, and the partition airbag 3 in the balloon blocker 4 is inflated to penetrate the inner side of the strip pipe 1 to seal the inner side of the strip pipe 1, so that the valve body 2 can be replaced smoothly to avoid the risk of gas leakage. When the strip pipe 1 is disassembled without stopping operation, some dangerous gas will still remain in the strip pipe 1.
