Description

Technical Field

[0001] This utility model relates to the technical field of pipeline maintenance tools, and in particular to a sewage discharge tool for gas transmission valves. Background Technology

[0002] During the drain valve drainage process, an Allen wrench is used to loosen the Allen bolt at the bottom of the drain nozzle, allowing the waste to be discharged along with the high-pressure natural gas. Because the waste is carried out by the high-pressure natural gas, excessive loosening of the drain nozzle can cause the drain valve to open suddenly, resulting in a burst of high-pressure natural gas carrying the waste, potentially causing injury. Furthermore, since the pipeline waste is hazardous waste, the ejected waste will adhere to surrounding pipes and drain valve supports, making it difficult to clean, polluting the environment, and affecting the aesthetics of the natural gas station. Therefore, a dedicated drain valve drainage tool is required to prevent waste from splashing.

[0003] Existing gas valve draining tools collect waste using a positioning frame and a safety detection and relief pipe assembly. However, the positioning frame is prone to loosening and falling off due to airflow impact, posing a risk of injury during draining. Furthermore, while collecting waste via a container is possible, the viscous grease from the drain valve often clogs the pipeline before reaching the container, resulting in poor practical performance. Additionally, the device's complex structure prevents its deployment in confined spaces at the valve base, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a sewage discharge tool for gas supply valves, which can prevent sewage from splashing when the sewage discharge valve is opened.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Gas valve draining tools, including:

[0007] The receiving tank is configured to collect waste discharged from the drain valve;

[0008] The unlocking structure is elongated and one end is detachably connected to the bottom of the receiving tank. When the receiving tank covers the outside of the drain valve, the unlocking structure can be rotated to loosen and open the drain valve.

[0009] An absorbent sponge is detachably attached to the inner wall of the receiving tank. The absorbent sponge can wrap around the outer periphery of the drain valve and absorb the dirt discharged from the drain valve.

[0010] Preferably, the receiving tank is circular, the adsorption sponge is annular, and the unlocking structure is located at the center of the bottom of the receiving tank.

[0011] Preferably, the absorbent sponge is interference-fitted with the receiving tank, and the maximum diameter of the outer ring of the absorbent sponge is greater than the opening diameter of the receiving tank.

[0012] Preferably, the absorbent sponge has multiple absorbent holes spaced apart in the depth direction and / or circumferential direction of the accommodating tank.

[0013] Preferably, the unlocking structure includes:

[0014] The mounting block has a locking groove at the bottom of the receiving groove, and the mounting block can be magnetically locked in the locking groove;

[0015] An unlocking lever is connected at one end to the mounting block, and the cross-section of the end of the unlocking lever away from the mounting block is hexagonal.

[0016] Preferably, the mounting block is rectangular.

[0017] Preferably, the device also includes a handle, which is elongated and detachably connected at one end to the receiving groove.

[0018] Preferably, the handle is provided with an anti-slip structure.

[0019] The beneficial effects of this utility model are:

[0020] When the receiving tank is placed outside the drain valve, rotating the receiving tank loosens the unlocking mechanism and opens the drain valve. When the pressure difference between the inside and outside of the drain valve is large, the receiving tank can prevent the discharged waste from splashing onto the workers, improving operational safety. The absorbent sponge can wrap around the outer periphery of the drain valve and absorb the waste discharged from the drain valve, thus preventing the discharged waste from flowing out of the opening of the receiving tank, eliminating the need for further cleaning and improving operational convenience. After the waste is discharged, rotating the receiving tank in the opposite direction drives the unlocking mechanism to close the drain valve again. The process is simple, convenient, and highly efficient. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-3As shown, this utility model provides a sewage discharge tool for gas valves, used to open and close the sewage discharge valve. The sewage discharge tool includes a receiving tank 1, an unlocking structure 2, and an absorbent sponge 3. The receiving tank 1 is configured to collect sewage discharged from the sewage discharge valve; the unlocking structure 2 is elongated, with one end detachably connected to the bottom of the receiving tank 1. When the receiving tank 1 covers the outside of the sewage discharge valve, the unlocking structure 2 can be rotated to loosen and open the sewage discharge valve; the absorbent sponge 3 is detachably attached to the inner wall of the receiving tank 1, and can wrap around the outer periphery of the sewage discharge valve, absorbing the sewage discharged from the valve.

[0034] When the receiving tank 1 is placed outside the drain valve, rotating the receiving tank 1 will loosen the unlocking mechanism 2 and open the drain valve. When the pressure difference between the inside and outside of the drain valve is large, the receiving tank 1 can prevent the discharged sewage from splashing onto the workers, improving the safety of the operation. The absorbent sponge 3 can wrap around the outer periphery of the drain valve and absorb the sewage discharged from the drain valve, thereby preventing the discharged sewage from flowing out of the opening of the receiving tank 1, eliminating the need for cleaning again and improving the convenience of the operation. After the sewage is discharged, rotating the receiving tank 1 in the opposite direction will drive the unlocking mechanism 2 to close the drain valve again. The process is simple and convenient, and the operation efficiency is high.

[0035] Specifically, the receiving tank 1 is circular, the adsorption sponge 3 is annular, and the unlocking structure 2 is located at the center of the bottom of the receiving tank 1. With the above configuration, when the receiving tank 1 is placed over the drain valve, the drain outlet of the drain valve is located at the center of the bottom of the tank, and the adsorption sponge 3 can more evenly adsorb the dirt sprayed from the drain valve.

[0036] More specifically, the absorbent sponge 3 is interference-fitted with the receiving tank 1, and the maximum diameter of the outer ring of the absorbent sponge 3 is larger than the opening diameter of the receiving tank 1. This design allows the absorbent sponge 3 to be securely held in the receiving tank 1, preventing it from easily falling off and facilitating replacement.

[0037] In other embodiments, the adsorbent sponge 3 can also be bonded to the inner wall of the accommodating tank 1 using adhesives commonly used in the art, so as to further improve the connection strength between the two and prevent the adsorbent sponge 3 from separating from the inner wall of the accommodating tank 1 after adsorbing too much dirt.

[0038] Specifically, the adsorbent sponge 3 has multiple adsorption holes 31 spaced apart in the depth direction and / or circumferential direction of the receiving tank 1. The adsorption holes 31 increase the specific surface area of ​​the adsorbent sponge 3, thereby improving its adsorption capacity for dirt.

[0039] Specifically, the unlocking structure 2 includes a mounting block 21 and an unlocking rod 22. The bottom of the accommodating groove 1 has a locking groove, allowing the mounting block 21 to be magnetically locked into it. One end of the unlocking rod 22 is connected to the mounting block 21, and the cross-section of the end of the unlocking rod 22 away from the mounting block 21 is hexagonal. This configuration allows the mounting block 21 to be magnetically locked into the locking groove and facilitates installation and disassembly. The hexagonal cross-section of the end of the unlocking rod 22 away from the mounting block 21 is adapted to the hexagonal bolt structure of existing drain valves.

[0040] In other embodiments, the unlocking structure 2 is provided in various ways. The specific form of the cross section of the unlocking rod 22 at the end away from the mounting block 21 includes, but is not limited to, a straight line, a cross, etc., to adapt to different forms of bolt structures of the sewage outlet and improve versatility.

[0041] In other embodiments, the mounting block 21 can also be locked in the locking groove by bolts or snap-fit ​​structures in the prior art, the principle and specific structure of which will not be described in detail here.

[0042] More specifically, the mounting block 21 is rectangular. With the above configuration, the torque when rotating the receiving groove 1 can be transmitted to the unlocking rod 22 through the mounting block 21, preventing relative sliding between the mounting block 21 and the receiving groove 1, thereby improving reliability and durability.

[0043] Specifically, the gas valve drain tool also includes a handle 4, which is elongated and detachably connected at one end to the receiving tank 1. The handle 4 facilitates the rotation of the receiving tank 1 by the operator, improving the ease of operation.

[0044] For example, in this embodiment, the handle 4 is specifically a rod-shaped structure, and one end is detachably connected to the outer wall of the receiving groove 1 by a bolt structure. With the above configuration, when the worker rotates the handle 4 with the unlocking structure 2 as the center, the rod-shaped structure can play the role of a force-saving lever, improving work efficiency while saving more effort.

[0045] For example, in this embodiment, the handle 4 is provided with an anti-slip structure. The anti-slip structure can be an anti-slip pad, such as a rubber pad; or, the anti-slip structure can be an anti-slip protrusion, which can be a dotted protrusion or a textured protrusion of any shape, as long as it can increase the contact friction between its location and the worker's hand. The specific form is in accordance with the prior art and is not specifically limited in this embodiment.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
