Description

Technical Field

[0001] The utility model relates to the technical field of sealing performance detection, in particular to a sealing performance detection device for a discharge valve. Background Art

[0002] A discharge valve is a special valve installed at the bottom of a reactor or other storage equipment to control and regulate the discharge of materials. According to the different structures and working principles, discharge valves can be divided into many types, such as upward expansion type, downward expansion type, plunger type and ball valve type. The main function of these valves is to control the flow direction of fluids or materials during the production process, and to regulate and control the parameters of the conveying medium. Discharge valves are indispensable components in the industrial production process. Their diversity and functionality provide convenience and guarantee for various processes. At present, discharge valves are widely used in thermal power plants.

[0003] After the discharge valve is produced, it is necessary to test the sealing performance of the discharge valve. The existing testing method is to first put the discharge valve into water, and observe whether bubbles appear in the sealing valve in the water to determine whether the sealing performance of the discharge valve is qualified. However, this method requires manual labor to repeatedly take the sealing valve out of the water, which increases manual fatigue and affects the detection efficiency of the discharge valve.

[0004] Therefore, a discharge valve sealing performance detection device is proposed. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] container;

[0009] The container is filled with water;

[0010] The outer wall of the container is fixed with a connection seat, a motor is installed on the top of the connection seat, the output end of the motor is connected with a screw rod in cooperation with a coupling, and a shaft sleeve is installed on the outer wall of the screw rod;

[0011] A connecting strip is fixed on the outer wall of the shaft sleeve, and a placing frame is fixed on the outer wall of the connecting strip.

[0012] Preferably, the bottom of the placement frame is in a grid shape.

[0017] Preferably, a compression spring is provided outside the fixing rod, one end of the compression spring is fixed to the auxiliary plate, and the other end of the compression spring is fixed to the connecting plate.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model places the discharge valve into a placement frame, then starts a motor, and the motor drives the screw rod to work. At this time, driven by the shaft sleeve, the placement frame will move downward. When the water in the container completely submerges the discharge valve, the bubbles are observed to judge the sealing performance of the discharge valve. Then, the motor is started again. At this time, driven by the shaft sleeve, the placement frame will move upward. When the discharge valve is separated from the water, the worker can take out the discharge valve in the placement frame. Compared with the existing method, the utility model does not need manual labor to directly fish out the discharge valve from the inside of the container, but adopts corresponding mechanical equipment to pre-take out the discharge valve from the inside of the container, which greatly reduces the labor intensity of manual labor and improves the detection efficiency of the discharge valve.

[0020] The utility model places the fixing bar inside the connection groove, and then under the action of the compression spring, the fixing rod is driven to be clamped into the first clamping hole and the second clamping hole, so that the fixing bar can be fixed. Under the action of the fixing bar, the discharge valve inside the placement frame can be fixed, so as to prevent the discharge valve from moving in the water and generating bubbles, thereby improving the detection accuracy of the discharge valve.

[0021] By pulling the fixing rod, the compression spring will perform corresponding stretching movement. After one end of the fixing rod is disengaged from the second clamping hole, the fixing bar can be disassembled to prevent the fixing bar from interfering with the worker in taking out the discharging valve, which is more convenient to use.

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.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Embodiment 1:

[0030] See also Figure 1 , 2 The utility model provides a technical solution: To achieve the above-mentioned purpose, the utility model provides the following technical solution: A discharge valve sealing performance detection device, comprising: a container 1; water is filled inside the container 1; a connecting seat 2 is fixed to the outer wall of the container 1, a motor 4 is installed on the top of the connecting seat 2, a screw rod 5 is connected to the output end of the motor 4 through a coupling, and a shaft sleeve 6 is installed on the outer wall of the screw rod 5; a connecting strip 7 is fixed to the outer wall of the shaft sleeve 6, a placement frame 8 is fixed to the outer wall of the connecting strip 7, and the bottom of the placement frame 8 is in a grid shape.

[0031] Specifically, the utility model places the discharge valve into the placement frame 8, then starts the motor 4, and the motor 4 drives the screw rod 5 to work. At this time, driven by the shaft sleeve 6, the placement frame 8 will move downward. When the water in the container 1 completely submerges the discharge valve, the air bubbles are observed to judge the sealing performance of the discharge valve, and then the motor 4 is started again. At this time, driven by the shaft sleeve 6, the placement frame 8 will move upward. When the discharge valve is separated from the water, the worker can take out the discharge valve in the placement frame 8. Compared with the existing method, the utility model does not need to manually fish out the discharge valve directly from the container 1, but uses corresponding mechanical equipment to pre-take the discharge valve out of the container 1, which greatly reduces the labor intensity of manual labor and improves the detection efficiency of the discharge valve.

[0032] It should be noted that, since the bottom of the placement frame 8 is in a grid shape, water can enter the bottom of the placement frame 8 , so that the water inside the container 1 can smoothly enter the inside of the placement frame 8 .

[0033] Embodiment 2:

[0034] See also Figure 1-4 The utility model provides a technical solution: a device for detecting the sealing performance of a discharge valve, a placing frame 8 is provided with connecting grooves 9 at the front and rear ends, a fixing strip 10 is connected in the connecting grooves 9, connecting plates 11 are fixed at both ends of the fixing strip 10, a first clamping hole 12 is provided on the outer wall of the connecting plate 11, and a second clamping hole 13 matching the first clamping hole 12 is provided at the front and rear ends of the placing frame 8; a fixing rod 14 is clamped in the first clamping hole 12 and the second clamping hole 13, an auxiliary plate 15 is fixed at one end of the fixing rod 14, a compression spring 3 is provided outside the fixing rod 14, one end of the compression spring 3 is fixed to the auxiliary plate 15, and the other end of the compression spring 3 is fixed to the connecting plate 11.

[0035] Specifically, the utility model places the fixing bar 10 inside the connecting groove 9, and then drives the fixing rod 14 to be clamped into the first clamping hole 12 and the second clamping hole 13 under the action of the compression spring 3, so that the fixing bar 10 can be fixed. Under the action of the fixing bar 10, the discharge valve inside the placement frame 8 can be fixed to prevent the discharge valve from moving in the water and generating bubbles, thereby improving the detection accuracy of the discharge valve;

[0036] By pulling the fixing rod 14, the compression spring 3 will perform a corresponding stretching movement.

It is more convenient to use and further improves the detection accuracy of the discharge valve.

[0037] Working principle:

[0038] First, the discharge valve is placed in the placement frame 8, and then the motor 4 is started. The motor 4 drives the screw rod 5 to work. At this time, driven by the shaft sleeve 6, the placement frame 8 will move downward. When the water in the container 1 completely submerges the discharge valve, the bubbles are observed to judge the sealing performance of the discharge valve. Then the motor 4 is started again. At this time, driven by the shaft sleeve 6, the placement frame 8 will move upward. When the discharge valve is separated from the water, the worker can take out the discharge valve in the placement frame 8. Compared with the existing method, the utility model does not require manual labor to directly retrieve the discharge valve from the container 1, but adopts corresponding mechanical equipment to pre-take the discharge valve out of the container 1, which greatly reduces the labor intensity of manual labor and improves the detection efficiency of the discharge valve.

[0039] Secondly, by placing the fixing strip 10 into the connecting groove 9, the fixing rod 14 is then driven by the compression spring 3 to engage with the first engaging hole 12 and the second engaging hole 13, so that the fixing strip 10 can be fixed. Under the action of the fixing strip 10, the discharge valve inside the placement frame 8 can be fixed to prevent the discharge valve from moving in the water and generating bubbles, thereby improving the detection accuracy of the discharge valve.

[0040] Finally, by pulling the fixing rod 14, the compression spring 3 will perform a corresponding stretching movement. After one end of the fixing rod 14 is disengaged from the second clamping hole 13, the fixing bar 10 can be disassembled to prevent the fixing bar 10 from interfering with the worker's removal of the discharge valve. It is more convenient to use and further improves the detection accuracy of the discharge valve.
