Abstract
Description
Technical Field
[0001] This utility model belongs to the field of venting PE ball valves, specifically, it relates to a press-fit type integrated stainless steel double venting PE ball valve. Background Technology
[0002] A venting ball valve is a safety warning device for pipelines transporting flammable and explosive gases. When a temporary cause causes the pressure at the control point to exceed the set value, i.e., the bubble bursting pressure, a certain amount of gas is released.
[0003] The existing venting PE ball valves do not have a self-heating structure for buried pipelines, which makes the pipelines prone to freezing when the temperature is too low. Furthermore, since the handle of the venting valve is located inside the pipeline well, small animals such as rats can easily step on the valve handle, causing the venting valve to be accidentally opened or closed. In view of this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a press-fit integrated stainless steel double-vent PE ball valve.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A press-fit integrated stainless steel double vent PE ball valve includes a main valve body, a vent ball valve, a heat insulation and heating component, and an anti-accidental contact component. Both ends of the main valve body are connected to the inner lining end for connecting the main gas pipeline. At the top of the connection between the two inner lining ends and the main valve body, a PE pipe connected to the vent ball valve is connected. The main gas pipeline, the two PE pipes, and the outer casing of the top sheath in the middle of the main valve body are all fitted with a heat insulation and heating component.
[0007] The top end of the sheath tube is provided with a twist square head. An anti-accidental contact component for fixing the handle of the venting ball valve is installed on the outside of the upper end of the sheath tube. The anti-accidental contact component includes a first pipe clamp, a mounting rod, a miniature pen-type electric push rod, a plug connector, and a guide rod. The front and rear ends of the first pipe clamp are fixed with mounting rods. Pen-type electric push rods are fixed inside the two mounting rods. The telescopic end of each pen-type electric push rod passes through the mounting rod and is fixed to the plug connector. A guide rod is fixed to the side of the plug connector. The guide rod passes through and is connected to the guide cavity inside the wall of the mounting rod.
[0008] The handle has a positioning hole through the middle of its front end for inserting a connector.
[0009] Optionally, a telescopic dust cover is installed between the plug block and the mounting rod.
[0010] Optionally, the heat insulation and heating assembly includes a heat-conducting base pad, a heat-insulating sleeve, and a second pipe clamp. The heat-conducting base pad is provided with an electric heating wire inside, and a heat-insulating sleeve is wrapped around the outside of the heat-conducting base pad. The heat-insulating sleeve is fixed by the second pipe clamp.
[0011] Optionally, the electric heating wire is connected to the temperature controller at the front end of the controller via a wire. The controller is fixed to the outside of the sheath pipe by a third pipe clamp, and a temperature sensor is also installed on the front side of the controller. The detection end of the temperature sensor is located in the soil on the side of the PE pipe.
[0012] Optionally, the venting ball valve and the PE pipe are provided with a stainless steel inner liner ring, and the outer side of the stainless steel inner liner ring is provided with anti-detachment protrusions that abut against the inner wall of the PE pipe at equal intervals. The outer front end of the stainless steel inner liner ring is also provided with a groove for placing the anti-detachment ring. The PE pipe is press-fitted with a locking ring to prevent the PE pipe from slipping.
[0013] Optionally, the two locking rings are reinforced to the sheath tube by a front reinforcing plate and a rear reinforcing plate. Insertion holes are provided on both sides of the front end of the front reinforcing plate for the insertion end of the rear reinforcing plate to be inserted. An embedding groove for the locking ring to be inserted is reserved in the middle of both the front and rear reinforcing plates. An anti-disengagement strip for abutting the bottom of the locking ring is fixed on the rear side of the embedding groove.
[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0015] 1. This utility model uses a heat insulation and heating component to heat and insulate the outer casing, main gas pipe, and PE pipe connected to the main valve body, preventing the gas inside the pipe from freezing due to excessively low temperatures and affecting the use of the device. When the temperature sensor detects that the temperature of the buried soil is too low, the electric heating wire will be activated by the thermostat and the temperature released by the regulator will be adjusted to insulate the pipe and prevent freezing. Secondly, the anti-accidental contact component locks the handle of the vent ball valve, preventing rodents or small animals in the pipe well from crawling and causing the handle to open or close abnormally.

Detailed Implementation
[0032] The present invention will now be described in further detail with reference to the accompanying drawings.
[0033] Please see Figures 1 to 11 This utility model provides a technical solution: a press-fit integrated stainless steel double vent PE ball valve, including a main valve body 1, a vent ball valve 2, a heat insulation and heating component and an anti-accidental contact component. Both ends of the main valve body 1 are connected to the inner lining end for connecting the main gas pipeline. At the connection point between the two inner lining ends and the main valve body 1, the top of the connection point is connected to a PE pipe 3 that communicates with the vent ball valve 2. The main gas pipeline, the two PE pipes 3 and the outer casing 4 at the top of the middle part of the main valve body 1 are all fitted with a heat insulation and heating component.
[0034] The top end of the sheath tube 4 is provided with a twist square head 5. An anti-accidental contact component for fixing the handle 6 of the venting ball valve 2 is installed on the outside of the upper end of the sheath tube 4. The anti-accidental contact component includes a first pipe clamp 7, a mounting rod 8, a miniature pen-type electric push rod 9, a plug connector 10, and a guide rod 11. The mounting rod 8 is fixed at both the front and rear ends of the first pipe clamp 7. The pen-type electric push rod 9 is fixed inside the two mounting rods 8. The telescopic end of each pen-type electric push rod 9 passes through the mounting rod 8 and is fixed to the plug connector 10. The guide rod 11 is fixed on the side of the plug connector 10. The guide rod 11 passes through and is connected to the guide cavity inside the wall of the mounting rod 8.
[0035] A positioning hole for insertion of the connector 10 is provided through the center of the front end of the handle 6. Considering that the existing venting PE ball valve and the buried pipeline do not have an independent heating structure, the pipeline is prone to freezing when the temperature is too low. In addition, since the handle 6 of the venting valve is located inside the pipeline well, small animals such as rats can easily step on the valve body's switch handle 6, causing the venting valve to be opened or closed accidentally. This utility model uses a heat insulation and heating component to heat and insulate the outer sheath pipe 4, the main gas pipe and the PE pipe 3 connected to the main valve body 1, preventing the gas inside the pipeline from freezing due to low temperature and affecting the use of the device. When the temperature sensor 20 detects that the buried soil temperature is too low, the temperature controller 18 will activate the electric heating wire 14 and adjust the temperature released by the controller to insulate the pipeline and prevent freezing. Secondly, the anti-accidental touch component locks the handle 6 of the venting ball valve 2, preventing rats or small animals in the pipeline well from crawling and causing the handle 6 to open or close abnormally.
[0036] A telescopic dustproof sleeve 12 is installed between the plug-in block and the mounting rod 8. The dustproof accordion sleeve plays a role in preventing dust from adhering to the telescopic end of the pen-type electric push rod 9 and affecting the transmission.
[0037] The heat insulation and heating assembly includes a heat-conducting base pad 13, a heat insulation sleeve 15, and a second pipe clamp 16. The heat-conducting base pad 13 is equipped with an electric heating wire 14 inside. The heat insulation sleeve 15 is wrapped around the outside of the heat-conducting base pad 13 and is fixed by the second pipe clamp 16. The heat insulation and heating assembly prevents the pipe from freezing.
[0038] The electric heating wire 14 is connected to the thermostat 18 at the front end of the controller 17 via a wire. The controller 17 is fixed to the outside of the sheath pipe 4 via a third pipe clamp 19. A temperature sensor 20 is also installed on the front side of the controller 17. The detection end of the temperature sensor 20 is located in the soil on the side of the PE pipe 3. The temperature sensor 20 is used to detect the soil temperature of the buried pipeline, and the thermostat 18 is used to regulate the heating temperature of the electric heating wire 14.
[0039] Among them, the venting ball valve 2 and the PE pipe 3 are provided with a stainless steel inner liner ring 21, and the stainless steel inner liner ring 21 is provided with anti-detachment protrusion rings 22 at equal intervals on the outside of the stainless steel inner liner ring 21, which abut against the inner wall of the PE pipe 3. The outer front end of the stainless steel inner liner ring 21 is also provided with a groove for placing the anti-detachment ring 23. The PE pipe 3 is press-fitted with a locking ring 24 to prevent the PE pipe 3 from slipping. By setting the anti-detachment protrusion ring 22 and the anti-detachment ring 23 in conjunction with the locking ring 24, the PE pipe 3 sleeved on the outside of the stainless steel inner liner ring 21 plays a pressing role.
[0040] The two locking rings 24 are reinforced to the sheath tube 4 by the front reinforcing plate 25 and the rear reinforcing plate 26. The front reinforcing plate 25 has insertion holes on both sides of the front end for the insertion end 27 of the rear reinforcing plate 26 to be inserted. The middle of the front reinforcing plate 25 and the rear reinforcing plate 26 are reserved with the embedding groove 28 for the locking ring 24 to be inserted. The rear side of the embedding groove 28 is fixed with an anti-slip strip 29 for abutting the bottom of the locking ring 24. By setting the front reinforcing plate 25 and the rear reinforcing plate 26 to install the anti-slip strip 29 through the insertion end 27 and the insertion hole, the locking ring 24 located outside the PE tube 3 is abutted against, thereby preventing the locking ring 24 from slipping and affecting the sealing between the PE tube 3 and the stainless steel inner lining ring 21.
