Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water valve control, in particular to a piston type hydraulic control valve. Background Art
[0002] A hydraulic control valve is a valve that uses pipeline medium pressure as power to open, close and adjust. The valve can achieve the functions of opening, closing and controlling pipeline flow and pressure through the opening and closing functions. On this basis, the hydraulic transmission principle is used to control the opening height or closing of the valve disc, and the requirements on valve performance are met. The fluid in the pipeline is used as the hydraulic transmission medium without the need for an independent hydraulic pump station, which not only saves equipment investment, but also saves energy and can achieve the purpose of automatic control.
[0003] In the prior art, traditional valve products usually adopt a diaphragm structure. The valve realizes the opening and closing function through a diaphragm sheet, which is prone to vibration due to rapid changes in pressure and flow, loud noise, easy damage to the diaphragm, small flow rate, large pressure loss and other disadvantages. It is impossible to detect the water flow pressure and cannot intuitively detect the water flow pressure. Excessive water pressure may cause the valve to leak. Utility Model Content

[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a piston-type hydraulic control valve, which has the following beneficial effects:
[0014] 1. The piston-type hydraulic control valve, through the setting of the pressure spring and the piston button, cooperates with the use of the pressure pointer and the pressure piston, so that the device can observe the water pressure of the water inlet in real time, can avoid the leakage of the water valve caused by excessive water pressure, can observe the water pressure intuitively, and the pressure spring can be adjusted in real time according to the actual water pressure of the water inlet, so as to ensure that the water pressure is always kept within a safe and stable range. When the water pressure is too high, the spring will be compressed accordingly to prevent the water valve from leaking; when the water pressure is too low, the spring will expand moderately to ensure the smooth flow of water. The cleverness of this spring design is that it can automatically adapt to various water pressure changes, greatly improving the stability and durability of the water valve. The setting of the piston button also adds many functions to the valve. Through the up and down movement of the piston, the valve can be easily opened and closed, which is crucial for controlling the direction and flow of the water flow. At the same time, the piston button also plays a feedback role. When the water pressure is abnormal, the piston will send a signal to the maintenance personnel to remind them to perform maintenance in time. The valve is also equipped with a pressure pointer and a pressure piston. The pressure pointer can intuitively display the current water inlet pressure value, so that maintenance personnel can quickly understand the water pressure status. The pressure piston further strengthens the sealing performance of the valve, ensuring that the water valve can maintain good working condition under various pressure conditions.
[0015] 2. The piston-type hydraulic control valve has a piston button and a pressure piston that are separately set, so that the device can measure the water pressure while closing the water valve, avoiding valve body leakage caused by excessive water pressure. The pressure piston measures the pressure at the water inlet, and then controls the water output at the water outlet by controlling the height change of the piston button, which is more convenient for users.

DETAILED DESCRIPTION
[0021] 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.
[0022] See also Figure 1-4 , a piston-type hydraulic control valve comprises a valve body 1, a water inlet chamber 2 is arranged at the lower end of the valve body 1, a buffer inner chamber 4 is arranged at the upper end, and a water outlet chamber 3 is arranged on the right side, a pressure piston 5 is arranged in the water inlet chamber 2, and water flow limiting plates 6 are arranged on the left and right sides of the inner wall of the water inlet chamber 2, and the middle of the two water flow limiting plates 6 is a water outlet, a piston button 7 is sleeved on the upper end of the valve body 1, and the piston button 7 is provided with a spring groove 8, and a pressure spring 10 is sleeved between the upper end surface of the pressure piston 5 and the top end surface of the spring groove 8 through a slide rod 9, a pressure pointer 11 is extended in the circumferential direction on the upper end surface of the pressure piston 5, and the pressure pointer 11 passes through a pointer slide groove 12 arranged on the piston button 7, and a pressure scale is arranged on the outer wall of the pointer slide groove 12, and a water flow baffle extending between the water flow limiting plates 6 is arranged on the lower end surface of the pressure piston 5.
[0023] The valve body 1 of the piston hydraulic control valve is fixed at the corresponding position of the water treatment system to ensure the stability of the valve body 1. The water flow is introduced into the water inlet chamber 2 of the valve body 1 through the water inlet, and the water flow is pressure-regulated by the pressure piston 5 in the water inlet chamber 2. The pressure is buffered by the pressure spring 10 at the upper end surface of the pressure piston 5 and the top of the spring groove 8, and the piston button 7 and the pressure piston 5 are linked by the slide rod 9. The pressure pointer 11 is connected to the piston button 7 through the pointer slide 12. When the water pressure changes, the position change of the pressure piston 5 will be reflected on the pressure pointer 11, thereby indicating the current pressure value. The water flow after pressure regulation flows out from the water outlet, enters the water outlet chamber 3, and finally flows out through the water outlet.
[0024] Through the cooperation of the pressure piston 5 and the spring, the water pressure at the water inlet is adjusted in real time to ensure stable water pressure and prevent leakage of the valve body 1 caused by excessive water pressure. The design of the pressure pointer 11 and the pressure scale enables maintenance personnel to intuitively observe changes in water pressure, which is convenient for fault diagnosis and rapid repair. The setting of the piston button 7 allows the valve to be closed quickly, and at the same time, through the linkage with the pressure piston 5, the water pressure is measured and controlled. The overall structure is compact and easy to operate, suitable for various water treatment systems, and improves the utilization efficiency of water resources and the stability of the system. Through the design of the water flow limit plate 6, precise control of the water volume at the water outlet is achieved to meet the diverse needs of users.
[0025] The buffer displacement of the pressure spring 10 is smaller than the height of the pointer sliding groove 12 .
[0026] The upper half of the pressure piston 5 is arranged in the inner cavity of the piston button 7 , and the lower half is arranged in the water inlet cavity 2 of the valve body 1 .
[0027] The buffering displacement of the pressure spring 10 is smaller than the height of the pointer slot 12, which ensures that the piston button 7 can be appropriately displaced when subjected to changes in water pressure, thereby achieving buffering under the action of the pressure spring 10. This design helps to reduce the impact of water pressure on the valve body 1 and extend the service life of the valve. At the same time, due to the buffering effect of the pressure spring 10, the displacement of the piston button 7 is smaller, and the height of the pointer slot 12 can be reduced accordingly, making the overall structure more compact. In addition, since the displacement of the piston button 7 is smaller, the moving range of the pressure pointer 11 is also reduced accordingly, making the reading of the pressure scale more accurate and convenient for maintenance personnel to observe and operate. In short, this design helps to improve the stability and accuracy of the piston hydraulic control valve and provide users with a more reliable water treatment solution.
[0028] A sealing ring 13 is provided between the inner wall of the buffer inner cavity 4 of the valve body 1 and the outer wall of the pressure piston 5 .
[0029] By dividing the pressure piston 5 into two sections, the water inlet and the water outlet are independently controlled, and the adjustment accuracy and stability of the valve are improved. The design of the pressure piston 5 can automatically adjust according to the change of water pressure, so as to maintain the stability of the water flow. The design of the piston button 7 and the pressure pointer 11 enables the operator to intuitively understand the operating status and water pressure of the valve. The overall structure is compact, simple and practical, and is suitable for various water treatment systems.
[0030] The pressure piston 5 is provided with an arc water-blocking end surface 501 at the lower end and a limiting head 502 at the upper end. The diameter between the water-blocking end surface and the limiting head 502 is smaller than the aperture size of the inner wall of the water inlet chamber 2 of the valve body 1 and the inner wall of the buffer inner chamber 4 of the valve body 1.
[0031] The setting of the sealing ring 13 improves the sealing performance of the valve and ensures the stability and safety of the water flow. The tight fit of the sealing ring 13 reduces the possibility of water pressure leakage and prolongs the service life of the valve. The design of the piston button 7 and the pressure pointer 11 enables the operator to intuitively understand the operating status and water pressure of the valve. The overall structure is compact, simple and practical, and is suitable for various water treatment systems.
[0032] Working principle: First, the design of the piston button 7 enables the valve to monitor the water pressure in real time when it is closed. Through the cooperation of the piston button 7 and the pressure piston 5, the valve can quickly respond to changes in water pressure, so that it can be closed in time when the pressure is too high to prevent the valve body 1 from leaking. When water flows through the water inlet, the arc water-blocking end face 501 is pushed upward to open the water inlet chamber 2. The arc water-blocking end face 501 is pushed upward to make the pressure piston 5 move upward to compress the pressure spring 10, and the pressure pointer 11 rises at the same time. The water flow pressure of the water inlet chamber 2 can be observed intuitively through different scales. After the water flows in, it is discharged through the water outlet chamber 3. The water flow limit plate 6 and the water flow baffle set in the water outlet chamber 3 realize the opening and closing of the valve. The valve is closed by pressing the piston button 7 upward, and the valve is opened by pressing the piston button 7 downward. When the water flow pressure is too large, the buffer spring plays a buffering role on the valve, which not only improves the durability of the valve, but also greatly enhances its safety, effectively avoiding various problems that may be caused by excessive water pressure. Secondly, the pressure piston 5 plays a vital role in measuring the water inlet pressure. By accurately measuring the pressure of the water inlet, the valve can adjust the flow of the water outlet in real time to ensure the stable output of the water flow. This refined control not only meets the diverse needs of users, but also further improves the utilization efficiency of water resources and achieves the goal of energy conservation and emission reduction. In addition, the height change of the piston button 7 also makes it possible to control the water volume at the water outlet of the valve. By controlling the height of the piston button 7, the valve can flexibly adjust the flow rate of the water outlet, thereby achieving precise control of the water volume. This design provides greater convenience for users, allowing them to flexibly adjust the water volume according to actual needs, further optimizing the water treatment process.
