Description

Technical Field

[0001] The utility model relates to the technical field of valve detection mechanisms, in particular to a valve detection mechanism for pipeline valve processing. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems have a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] After the valve processing and production is completed, a valve detection mechanism is generally used to detect various conditions of the valve. Although the existing valve detection mechanism can detect various conditions of the valve and present them through specific data, the data cannot represent the specific actual situation. The existing valve detection mechanism cannot intuitively detect whether the valve is broken or leaking, which makes it easy for broken and leaking valves to be mixed with good products, thereby causing quality problems and economic losses, which is not conducive to use. Therefore, a valve detection mechanism for pipeline valve processing is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a valve detection mechanism for pipeline valve processing, which solves the problem that it is impossible to intuitively detect whether the valve is broken or leaking, which leads to the possibility of broken and leaking valves being mixed into good products, thus causing quality problems, resulting in economic losses and being unfavorable for use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve detection mechanism for pipeline valve processing, comprising a body frame and a valve, wherein a leak detection mechanism is arranged outside the body frame;

[0006] The leakage detection mechanism includes an air pump, a circulating water pump and a detection box fixedly connected to the top of the body frame, the left and right sides of the detection box are fixedly connected with connecting sleeves, the outside of the connecting sleeve is fixedly installed with a first solenoid valve, the end of the connecting sleeve located inside the detection box is fixedly connected with a telescopic butt tube, the top of the telescopic butt tube is fixedly connected to the left and right sides of the valve with a flange connecting plate, the top of the flange connecting plate is bonded with a rubber sealing gasket, the inner side of the flange hole of the flange connecting plate is provided with a locking bolt, the outer surface of the locking bolt is threadedly sleeved with a locking nut, and the inner side of the body frame is fixedly connected with a water storage tank.

[0007] Furthermore, the tops of the detection box and the water storage tank are not sealed, and a scale for measuring length and width is fixedly connected to the top of the detection box.

[0008] Furthermore, the air pump is connected to the connecting sleeve, and the circulating water pump is connected to the detection box and the water storage tank.

[0009] Furthermore, a drainage pipe having one end penetrating through and extending to the inner side of the water storage tank is fixedly connected to the bottom of the detection box, and a second solenoid valve is fixedly installed on the outer surface of the drainage pipe.

[0010] Furthermore, a sealing gasket for preventing water leakage is sleeved on the outer surface of the connecting sleeve, and a side surface of the sealing gasket is bonded and fixed to a side surface of the detection box.

[0011] Furthermore, a liquid level sensor for monitoring the liquid level is fixedly installed on the left side of the detection box, and a detector of the liquid level sensor penetrates and extends to the inner side of the detection box.

[0012] Furthermore, universal wheels for movement are rotatably connected around the bottom of the body frame, support plates are fixedly connected to the left and right sides of the body frame, an electric push rod for limiting is fixedly installed on the top of the support plate, and the output shaft of the electric push rod is fixedly connected to a grounding plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The valve detection mechanism for pipeline valve processing is provided with a leak detection mechanism. When in use, the staff only needs to cooperate with the flange connection plate, the locking bolt and the locking nut to make the telescopic butt joint and the valve for pipeline sealing. Then, start the circulating water pump to draw the water inside the water storage tank into the detection box and overflow the valve. Subsequently, open the first solenoid valve and start the air pump to introduce the outside air into the valve. At this time, since the valve is wrapped in water, when the valve has a leak, a large number of bubbles will be generated in the water body, and vice versa. Therefore, the staff can more intuitively detect whether the valve has a leak through the bubbles in the water body, effectively avoiding the situation where the leaky valve is mixed into the good product, thereby reducing the probability of product quality problems and being more conducive to use.

[0015] 2. The valve detection mechanism for pipeline valve processing can facilitate the staff to quickly measure the length and width data of the valve before detection by setting a scale, so as to record and avoid mixing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a valve detection mechanism for pipeline valve processing includes a body frame 1 and a valve 2, and a leak detection mechanism is arranged outside the body frame 1;

[0022] The leakage detection mechanism includes an air pump 3, a circulating water pump 4 and a detection box 5 fixedly connected to the top of the body frame 1, a connecting sleeve 6 is fixedly connected to the left and right sides of the detection box 5, a first solenoid valve 7 is fixedly installed on the outside of the connecting sleeve 6, and a telescopic butt pipe 8 is fixedly connected to one end of the connecting sleeve 6 located inside the detection box 5, and a flange connecting plate 9 is fixedly connected to the top of the telescopic butt pipe 8 and the left and right sides of the valve 2, a rubber sealing gasket is bonded to the top of the flange connecting plate 9, a locking bolt 10 is arranged on the inner side of the flange hole of the flange connecting plate 9, and a locking nut 11 is threadedly sleeved on the outer surface of the locking bolt 10, and a water storage tank 12 is fixedly connected to the inner side of the body frame 1. By setting up the leakage detection mechanism, when in use, the staff only needs to use the law The cooperation of the flange connecting plate 9, the locking bolt 10 and the locking nut 11 enables the telescopic butt joint 8 to be sealed with the valve 2. Then, the circulating water pump 4 is started to draw the water inside the water storage tank 12 into the detection box 5 and overflow the valve 2. Subsequently, the first solenoid valve 7 is opened and the air pump 3 is started to introduce the outside air into the valve 2. At this time, since the valve 2 is wrapped in water, when the valve 2 is leaking, a large number of bubbles will be generated in the water body, otherwise not. As a result, the staff can more intuitively detect whether the valve 2 is leaking through the bubbles in the water body, effectively avoiding the situation where the leaking valve 2 is mixed into the good product, thereby reducing the probability of product quality problems and being more conducive to use.

[0023] Among them, the tops of the detection box 5 and the water storage tank 12 are not sealed, and a scale 13 for measuring length and width is fixedly connected to the top of the detection box 5. By setting the scale 13, it is convenient for the staff to quickly measure the length and width data of the valve 2 before testing, so as to record and avoid mixing.

[0024] It should be noted that the air pump 3 is connected to the connecting sleeve 6, the circulating water pump 4 is connected to the detection box 5 and the water storage tank 12, and the bottom of the detection box 5 is fixedly connected to a drain pipe 14 with one end passing through and extending to the inside of the water storage tank 12. A second solenoid valve 15 is fixedly installed on the outer surface of the drain pipe 14. By setting the drain pipe 14 and the second solenoid valve 15, when the inspection is completed, the staff only needs to open the second solenoid valve 15 to discharge the water inside the detection box 5 into the water storage tank 12 through the drain pipe 14 for temporary storage, thereby achieving the effect of circulating water and avoiding waste.

[0025] It should be understood that a sealing gasket 16 is sleeved on the outer surface of the connecting sleeve 6 to prevent water leakage, and the side of the sealing gasket 16 is bonded and fixed to the side of the detection box 5. By providing the sealing gasket 16, the effect of enhancing the sealing is achieved, thereby preventing water leakage.

[0026] Among them, a liquid level sensor 17 for monitoring the liquid level is fixedly installed on the left side of the detection box 5. The detector of the liquid level sensor 17 penetrates and extends to the inner side of the detection box 5. By setting the liquid level sensor 17, the effect of monitoring the water level is achieved, thereby preventing water from overflowing from the opening of the detection box 5.

[0027] In addition, universal wheels 18 for movement are rotatably connected around the bottom of the body frame 1, support plates 19 are fixedly connected on the left and right sides of the body frame 1, and an electric push rod 20 for limiting is fixedly installed on the top of the support plate 19. The output shaft of the electric push rod 20 is fixedly connected to a grounding plate 21. By setting the universal wheels 18, the effect of easy movement is achieved, and the cooperation of the electric push rod 20 and the grounding plate 21 can achieve a limiting effect. Therefore, after the detection mechanism moves to the designated location, the grounding plate 21 is moved downward by the output shaft of the electric push rod 20, thereby contacting the ground, thereby avoiding position displacement of the detection mechanism.

[0028] The working principle of the above embodiment is:

[0029] When using the valve detection mechanism for pipeline valve processing, the staff first needs to place the valve 2 flat on the inner bottom wall of the detection box 5, and then, through the cooperation of the flange connection plate 9, the locking bolt 10 and the locking nut 11, the telescopic butt joint 8 is connected to the valve 2 for pipeline sealing, and then, the circulating water pump 4 is started to draw the water inside the water storage tank 12 into the detection box 5 and overflow the valve 2, and then, the first solenoid valve 7 is opened and the air pump 3 is started to introduce the outside air into the valve 2. At this time, since the valve 2 is wrapped in water, the staff only needs to observe whether there are a large number of bubbles in the water body and whether they are constantly floating upwards, so as to intuitively detect whether the valve 2 is leaking.
