Description

Technical Field

[0001] The utility model relates to the technical field of valve pressure detection machines, in particular to a movable regulating valve pressure hydraulic detection machine. Background Art

[0002] Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems need to be tested before leaving the factory. One of the important indicators includes valve sealing performance and pressure resistance data. The valve data needs to be tested using a valve pressure resistance testing machine.

[0003] Traditional valve testing machines are usually fixed, so the valve to be tested needs to be moved to the testing equipment. When some valves are heavy and large, they need to be lifted with the help of mechanical equipment, which makes valve pressure testing cumbersome and inefficient.

[0004] In view of this, we propose a movable regulating valve pressure hydraulic testing machine. Utility Model Content

[0016] (1) The movable regulating valve pressure hydraulic testing machine is provided with a lifting frame and a base. When the testing machine needs to test the valve, the universal wheel of the base is moved to move the upper testing machine of the base to the surface of the valve to be tested. The valve to be tested is lifted by the lifting frame, and then the valve is connected to the testing machine. In this way, during the testing process of the valve, there is no need to move the valve, and there is no need to use a lifting device to lift the valve, which simplifies the testing process and effectively improves the operating efficiency of the testing machine.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 - Figure 3 , the utility model provides a technical solution:

[0024] A movable regulating valve pressure hydraulic testing machine comprises a base 1, a pressure testing machine 2 and a lifting frame 3, wherein the pressure testing machine 2 is provided with two groups, the two groups of pressure testing machines 2 are respectively arranged on both sides of the surface of the base 1, and the lifting frame 3 is arranged between the two groups of pressure testing machines 2, the lifting frame 3 comprises a door frame 31 and a reel rod 32, the door frames 31 are provided with two, and the two door frames 31 are penetrated by a reel rod 32, a plurality of fixing rings 33 are fixed on the surface of the reel rod 32, and a traction belt 34 is respectively fixed on the surfaces of the plurality of fixing rings 33, and the end of the reel rod 32 is transmission-connected to a driving motor 35, the door frame 31 fixes the reel rod 32 just above the suspension groove 13, and the reel rod 32 is parallel to the connecting line of the two slideways 12, so that the valve fixed by the reel rod 32 through the sling is parallel to the sealing joints 24 at both ends, so that the sealing joint 24 can be quickly docked with the valve by moving forward and backward.

[0025] The base 1 includes a bottom plate 11 and a slide 12. The pressure testing machine 2 and the lifting frame 3 are installed together on the surface of the bottom plate 11. A suspension groove 13 is provided on the surface of the base 1. There are two slides 12, which are respectively arranged on both sides of the suspension groove 13. The suspension groove 13 allows the equipment to be closer to the valve. The suspension groove 13 reduces the number of valve movement times, so that the equipment can be moved directly above the valve to prevent the situation of lifting and moving again, and simplify the preparation work before testing as much as possible.

[0026] The pressure testing machine 2 includes a testing host 21 and a telescopic hose 22. There are two testing hosts 21, which are respectively arranged on both sides of the lifting frame 3. The telescopic hose 22 is fixed on the surface of the testing host 21. A sliding bracket 23 is fixed to the bottom end of the telescopic hose 22. A sealing joint 24 is connected to the end of the telescopic hose 22. The two testing hosts 21 are connected to both ends of the valve through the telescopic hose 22. The pressure resistance value of the valve in the application scenario is actually simulated by connecting the two ends of the valve, and at the same time, whether the valve seal is perfect is detected to prevent leakage.

[0027] There are two sliding brackets 23, which are respectively slidably connected to the slideways 12 on both sides of the suspension groove 13. The sliding brackets 23 slide linearly on the surface of the base 1 through the slideways 12, ensuring that the sliding brackets 23 effectively support the linear movement of the telescopic hose 22, ensuring that the telescopic hose 22 extends linearly, and preventing the telescopic hose 22 from bending and extending to cause damage to the pipeline.

[0028] The sealing joint 24 adopts an inverted cone structure, and the surface of the sealing joint 24 is wrapped with a rubber sealing ring. The inverted cone structure can effectively reduce the mismatch between the sealing joint 24 and the valve, and improve the adaptability of the sealing joint 24. At the same time, the sealing rubber ring on the surface plays a sealing connection and reduces the wear caused during the valve connection process.

[0029] The traction belt 34 is made of a wide nylon flat belt, and a plurality of universal wheels are arranged at the bottom end of the base plate 11. The wide flat belt traction belt 34 ensures effective support for the valve and stability of the valve during its ascent. Meanwhile, nylon has good wear resistance, and the plurality of universal wheels at the bottom end of the base plate 11 ensure that the universal wheels can effectively bear weight while moving.

[0030] When the movable regulating valve pressure hydraulic testing machine of the utility model is in use, the universal wheel moving device at the bottom end of the base 1 is used to move the device to the valve location that needs to be tested, so that the valve is located inside the hollow suspension groove 13 of the base 1, which is convenient for the lifting frame 3 to fix the valve, and then two traction belts 34 are fixed to the surface of the valve. The traction belt 34 is made of nylon flat belt, so that the valve can be stabilized on the surface of the nylon flat belt. After the fixation is completed, the driving motor 35 is started, and the driving motor 35 drives the reel rod 32 to rotate, and the fixing ring 33 on the surface of the reel rod 32 rotates synchronously, so that the traction belt 34 on the surface of the fixing ring 33 is rolled up, so that the valve fixed at the bottom end of the traction belt 34 rises, and the valve rises to a suitable After reaching the height, the winding can be stopped, the driving motor 35 can be turned off, the sealing joint 24 can be connected to the interface of the valve, and the sliding bracket 23 can be moved inside the slide 12 to drive the rope hose to extend and retract, so that the sealing joint 24 can move back and forth, and the sealing ring on the surface of the sealing joint 24 can be sealed with the valve. Since the sealing joint 24 adopts an inverted cone structure, the sealing joint 24 can adapt to valves of different sizes, reducing the tediousness of replacing the joint. Subsequently, the detection hosts 21 on both sides are started. The detection hosts 21 at both ends of the valve increase the internal pressure of the valve through the telescopic hose 22, thereby detecting the pressure resistance data of the regulating valve. Compared with the traditional pressure detection machine 2, the tediousness of moving and fixing the valve is reduced.
