Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure plate seat technology, and in particular to a pressure sealing pressure plate seat. Background Technology
[0002] Most water valves on the market today use a method of filling the inner wall of the valve cover with a sealant, and then achieving a sealing effect between the valve stem and the valve cover by the pressure of the pressure plate seat. The pressure plate seat generally consists of a pressure plate and a seat body. The seat body is fixedly fitted onto the valve stem, while the pressure plate is used to press against the pressure pipe inserted into the valve stem and is connected to the seat body by multiple screws and nuts.
[0003] After the pressure plate is fixed to the base by multiple sets of screw and nut fasteners, the nuts may rotate after a long period of use, which may cause the connection between the pressure plate and the base to loosen. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pressure sealing plate seat.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pressure sealing plate seat includes an annular pressure plate and a seat body for fixing and fitting onto a valve stem. Multiple screws are vertically fixedly mounted on the upper surface of the seat body in a circumferential shape. The upper surface of the pressure plate has multiple circumferential openings for the screws to pass through. Locking nuts are threaded onto the screws. An annular opening is formed on the outer wall of the pressure plate. A first spring rod is symmetrically fixedly mounted within the annular opening. One end of the first spring rod is fixedly mounted with an arc-shaped plate that fits against the outer wall of the pressure plate. A limiting plate is fixedly mounted at the top of the arc-shaped plate. The limiting plate is located above the pressure plate, and the distance between its lower surface and the upper surface of the pressure plate is sufficient to allow the locking nuts to enter. Limiting components are provided on the upper surfaces of the two limiting plates to prevent them from moving away from each other.
[0007] To better achieve the above objectives, the present invention adopts a further technical solution: the limiting component includes two mounting blocks, a rotating shaft horizontally rotatably mounted between the two mounting blocks, an L-shaped locking block and a limiting block fixedly sleeved on the rotating shaft, the two mounting blocks being fixedly mounted on the upper surface of one of the limiting plates, the limiting block being fixedly mounted on the upper surface of the other limiting plate and cooperating with the locking block, the locking block being connected to one of the mounting blocks through an elastic component, the elastic component including a torsion spring sleeved on the rotating shaft, the two ends of the torsion spring being fixedly connected to the locking block and the mounting block respectively.
[0008] To better achieve the above objectives, the present invention adopts a further technical solution: the outer ring wall of the pressure plate is provided with a pressing component, the pressing component is used to control the two arc-shaped plates to move away from each other, the pressing component includes two second spring rods symmetrically fixedly installed on the outer ring wall of the pressure plate and two pairs of I-shaped blocks, one end of the second spring rod is fixedly installed with a mounting plate, a pair of connecting rods are fixedly installed on the upper surface of the mounting plate, inclined plates are symmetrically fixedly installed on the side wall of the arc-shaped plates, the surface of the inclined plates is provided with sliding openings, and multiple I-shaped blocks are respectively fixedly connected to multiple connecting rods and slidably arranged in multiple sliding openings.
[0009] The beneficial effects of this utility model are: through the cooperation between the first spring rod, the arc plate and the limiting plate, after the pressure plate and the seat are connected, the vertical movement and rotation of the locking nuts that are threaded onto the multiple screws can be restricted, so as to avoid the connection between the pressure plate and the seat becoming loose due to the rotation of the locking nuts.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] Reference Figures 1-6The pressure sealing plate seat includes an annular pressure plate 1 and a seat body 2 for fixing and fitting onto a valve stem. Multiple screws 3 are vertically fixedly installed on the upper surface of the seat body 2 in a circumferential shape. Multiple through holes for the screws 3 to pass through are opened on the upper surface of the pressure plate 1 in a circumferential shape. Locking nuts 4 are threaded onto the screws 3. An annular opening 5 is opened on the outer annular wall of the pressure plate 1. A first spring rod 6 is symmetrically fixedly installed inside the annular opening 5. An arc-shaped plate 7 that fits against the outer annular wall of the pressure plate 1 is fixedly installed at one end of the first spring rod 6. A limiting plate 8 is fixedly installed at the top of the arc-shaped plate 7. The limiting plate 8 is located above the pressure plate 1, and the distance between the lower surface of the limiting plate 8 and the upper surface of the pressure plate 1 is sufficient to allow the locking nuts 4 to enter.
[0019] When it is necessary to install the pressure plate 1 and the seat 2, simply put the pressure plate 1 on the multiple screws 3 until the lower surface of the pressure plate 1 abuts against the top of the pressure tube located inside the valve stem. At this time, control the two arc plates 7 to move away from each other, so that the two limiting plates 8 move away from each other. The two first spring rods 6 will then be stretched. Then, thread the multiple locking nuts 4 onto the multiple screws 3 respectively. After connecting the pressure plate 1 and the seat 2, loosen the two arc plates 7. The two arc plates 7 will then bring the two limiting plates 8 closer to each other and abut against each other under the elastic potential energy of the two first spring rods 6. After resetting, the lower surface of the two limiting plates 8 will abut against the upper surface of the multiple locking nuts 4. At this time, the multiple locking nuts 4 will be located between the limiting plates 8 and the pressure plate 1. The limiting plates 8 can restrict the rotation and vertical movement of the locking nuts 4.
[0020] The upper surfaces of the two limiting plates 8 are provided with limiting components to prevent the two limiting plates 8 from moving away from each other. The limiting components include two mounting blocks 9, a rotating shaft horizontally rotatably mounted between the two mounting blocks 9, an L-shaped locking block 10 fixedly sleeved on the rotating shaft, and a limiting block 11. The two mounting blocks 9 are respectively fixedly mounted on the upper surface of one of the limiting plates 8, and the limiting block 11 is fixedly mounted on the upper surface of the other limiting plate 8 and cooperates with the locking block 10. The locking block 10 is connected to one of the mounting blocks 9 through an elastic member, which includes a component sleeved on the rotating shaft. The torsion spring 12 has its two ends fixedly connected to the locking block 10 and the mounting block 9, respectively. Under the elastic potential energy of the torsion spring 12, the locking block 10 is initially horizontal. When the two limiting plates 8 come into contact, the locking block 10 will contact the limiting block 11 and form a locking. At this time, the two limiting plates 8 cannot move away from each other, so as to avoid the limiting plates 8 from moving due to the influence of vibration force, which would cause the limiting effect on the locking nut 4 to disappear. When it is necessary to release the restriction on the limiting plate 8, simply rotate the locking block 10 so that the locking block 10 is no longer in contact with the limiting block 11.
[0021] The outer ring wall of the pressure plate 1 is provided with a pressing component. The pressing component is used to control the two arc-shaped plates 7 to move away from each other. The pressing component includes two second spring rods 13 symmetrically fixedly installed on the outer ring wall of the pressure plate 1 and two pairs of I-shaped blocks 14. One end of the second spring rod 13 is fixedly installed with a mounting plate. A pair of connecting rods 15 are fixedly installed on the upper surface of the mounting plate. Inclined plates 16 are symmetrically fixedly installed on the side walls of the arc-shaped plates 7. Sliding openings 17 are opened on the surface of the inclined plates 16. Multiple I-shaped blocks 14 are fixedly connected to multiple connecting rods 15 respectively and are slidably arranged in multiple sliding openings 17 respectively.
[0022] When it is necessary to control the two curved plates 7 and the two limiting plates 8 to move away from each other, simply control the two mounting plates to move closer together by hand. At this time, both second spring rods 13 will retract, and multiple I-shaped blocks 14 will slide in multiple sliding holes 17 respectively. Under the action of the inclined plane, the two curved plates 7 and the two limiting plates 8 will move laterally away from each other, without the need to control the two curved plates 7 and the two limiting plates 8 to move away from each other individually.
[0023] When installing the pressure plate 1 and the seat 2, this utility model simply involves placing the pressure plate 1 on multiple screws 3 until the lower surface of the pressure plate 1 abuts against the top of the pressure tube located inside the valve stem. At this point, the two arc-shaped plates 7 are then moved away from each other, causing the two limiting plates 8 to move away from each other as well. Then, multiple locking nuts 4 are threaded onto the multiple screws 3. After connecting the pressure plate 1 and the seat 2, the two arc-shaped plates 7 are released. Under the elastic potential energy of the two first spring rods 6, the two arc-shaped plates 7 will bring the two limiting plates 8 closer together and abut against each other. After resetting, the lower surfaces of the two limiting plates 8 will abut against the upper surfaces of the multiple locking nuts 4. At this point, the multiple locking nuts 4 will be located between the limiting plates 8 and the pressure plate 1. The limiting plates 8 can restrict the rotation and vertical movement of the locking nuts 4, preventing the connection between the pressure plate 1 and the seat 2 from loosening due to the rotation of the locking nuts 4.
