Description

Technical Field

[0001] This utility model relates to the field of steam emission technology, and in particular to a steam cooling staged emission valve structure. Background Technology

[0002] In industrial applications, equipment involving steam discharge and cooling typically requires safe and efficient pressure relief and cooling structures. Traditional steam discharge valve structures present the following technical problems in the pressure relief and cooling process:

[0003] Insufficient ease of operation: It requires manual operation by staff to open the cooling water injection pipe, and cannot be automatically controlled according to changes in steam pressure, which poses a risk of response lag or human error.

[0004] Low cooling water utilization: Manual operation mode may lead to premature injection or excessive use of cooling water, resulting in water waste; at the same time, if the cooling water evaporates before the steam enters the pressure relief port, it may cause abnormal pressure rise in the system, affecting the accuracy of steam pressure monitoring.

[0005] Cooling efficiency and impurity handling defects: In traditional structures, the contact between cooling water and steam is insufficient, resulting in a slow cooling rate; moreover, there is a lack of effective function to intercept impurities in the steam, which may cause wear or blockage to internal components of the device, affecting the stability and service life of the equipment. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a steam cooling staged discharge valve structure. The valve uses steam pressure to push a piston against the spring force, and a pressure sensor is installed at the end of the spring away from the piston. When the piston moves to be tangential to the pressure relief port, the pressure transmitted by the spring to the pressure sensor will reach a threshold, and a signal will be transmitted to the controller, causing it to open the water injection pipe without manual operation. This also reduces the waste of cooling water and prevents the pressure increase caused by cooling water evaporation before the steam enters the pressure relief port from affecting the actual steam pressure. The cooling water is guided to the top of the grid plate, allowing it to flow on the surface of the grid plate, ensuring full contact between the cooling water and the steam for rapid cooling. This also prevents a large amount of cooling water from being washed away and blocks impurities in the steam, preventing damage to the device.

[0007] This utility model also provides a steam cooling staged discharge valve structure as described above, comprising: a discharge seat, wherein a steam port is provided inside the discharge seat, a grid plate is fixedly connected to the inner side wall of the steam port, a water injection pipe is connected to the top of the grid plate, a piston is slidably connected to the inner side wall of the steam port, a spring is fixedly connected to the end face of the piston, a pressure sensor is provided at the end of the spring away from the piston, a controller is provided inside the discharge seat, and a pressure relief port is provided inside the discharge seat; a high-pressure tank, a medium-pressure tank and a low-pressure tank are provided on the side of the high-pressure tank, a discharge port is connected to the end of the low-pressure tank, a pressure gauge is provided at the top of the high-pressure tank, a drain pipe is connected to the bottom of the high-pressure tank, and a drain valve is provided inside the drain pipe. The above components utilize steam pressure to push the piston against the spring force. A pressure sensor is located at the end of the spring away from the piston. When the piston moves to be tangential to the pressure relief port, the pressure transmitted from the spring to the pressure sensor will reach the threshold and send a signal to the controller, which will open the water injection pipe without manual operation. This reduces the waste of cooling water and prevents the pressure increase caused by cooling water evaporation before the steam enters the pressure relief port from affecting the actual steam pressure. The cooling water is guided to the top of the grid plate, allowing it to flow on the surface of the grid plate, ensuring full contact between the cooling water and the steam for rapid cooling. This also prevents a large amount of cooling water from being washed away and blocks impurities in the steam, preventing them from damaging the device.

[0008] According to the steam cooling staged discharge valve structure of this utility model, the side surface of the water injection pipe is fixedly connected to the inner wall of the discharge seat, and the side surface of the pressure sensor is fixedly connected to the inner wall of the discharge seat. These components provide support for the water injection pipe to ensure stable injection of cooling water, and provide support for the pressure sensor to ensure stable detection of the device's status.

[0009] According to the steam cooling staged discharge valve structure described in this utility model, the controller is connected to the water injection pipe and the pressure sensor via wires, and the pressure relief ports are multiple and arrayed inside the discharge seat. These components enable the pressure sensor to transmit information to the controller, which then controls the water injection pipe to ensure steam cooling and reduce cooling water waste. The multiple pressure relief ports allow for faster steam discharge.

[0010] According to the steam cooling staged discharge valve structure described in this utility model, the pressure relief port is connected to the steam port, and the end of the pressure relief port away from the steam port is connected to the end of the discharge seat away from the steam port. Through these components, the steam port can guide steam into the pressure relief port and direct the steam to a high-pressure tank, a medium-pressure tank, or a low-pressure tank.

[0011] According to the steam cooling staged discharge valve structure described in this utility model, the discharge seats are three in number and are respectively arranged on the sides of the high-pressure tank, the medium-pressure tank, and the low-pressure tank. These components enable the device to automatically discharge steam in stages.

[0012] According to the steam cooling staged discharge valve structure described in this utility model, there are three components: a pressure gauge, a drain pipe, and a drain valve, which are located at the bottom of the high-pressure tank, the medium-pressure tank, and the low-pressure tank. These components are used to detect the internal pressure of the high-pressure tank, the medium-pressure tank, and the low-pressure tank, and to drain any accumulated water from them.

[0013] According to the steam cooling staged discharge valve structure described in this utility model, the pressure gauge and drain valve are connected to the controller via wires. These components facilitate the extraction of internal pressure from the high-pressure tank, medium-pressure tank, and low-pressure tank, enabling control of the drain valve.

[0014] According to the steam cooling graded discharge valve structure of this utility model, the bottom end of the grid plate is connected to a chip removal groove to facilitate the removal of impurities.

[0015] Beneficial effects:

[0016] Compared with the prior art, this utility model uses steam pressure to push the piston against the spring force to move. A pressure sensor is set at the end of the spring away from the piston. When the piston moves to be tangent to the pressure relief port, the pressure transmitted by the spring to the pressure sensor will also reach the threshold and transmit the signal to the controller, so that it can open the water injection pipe without manual operation by the operator. It can also reduce the waste of cooling water and prevent the pressure increase caused by the evaporation of cooling water before the steam enters the pressure relief port from affecting the actual steam pressure. The cooling water will be guided to the top of the grid plate, so that the cooling water flows on the surface of the grid plate, allowing the cooling water to fully contact the steam and quickly cool the steam. It can also prevent a large amount of cooling water from being washed away and block impurities in the steam to prevent them from damaging the device. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a steam cooling staged discharge valve structure, comprising: a discharge seat 1, a steam port 2 inside the discharge seat 1, a grid plate 3 fixedly connected to the inner wall of the steam port 2, a chip removal groove connected to the bottom end of the grid plate 3, a water injection pipe 4 connected to the top end of the grid plate 3, a side surface of the water injection pipe 4 fixedly connected to the inner wall of the discharge seat 1, a piston 5 slidably connected to the inner wall of the steam port 2, a spring 6 fixedly connected to the end face of the piston 5, a pressure sensor 7 disposed at the end of the spring 6 away from the piston 5, a side surface of the pressure sensor 7 fixedly connected to the inner wall of the discharge seat 1, a controller 8 disposed inside the discharge seat 1, the controller 8 being connected to the water injection pipe 4 and the pressure sensor 7 via wires, and a pressure relief port 9 inside the discharge seat 1, having several pressure relief ports 9 arranged in an array inside the discharge seat 1, the pressure relief port 9 being connected to the steam port 2, and the end of the pressure relief port 9 away from the steam port 2 being connected to the end of the discharge seat 1 away from the steam port 2.

[0026] Specifically, steam is introduced into the discharge seat 1 through steam port 2. The steam, through its own pressure, pushes piston 5 to slide, resisting the sliding of spring 6. When piston 5 is tangent to pressure relief port 9, the pressure of spring 6 on pressure sensor 7 reaches a predetermined value, which transmits a signal to controller 8. This activates water injection pipe 4 to inject cooling water into grid plate 3, allowing the cooling water to flow on the surface of grid plate 3. This ensures that steam can fully contact the cooling water, rapidly cooling the steam and preventing a large amount of cooling water from being washed away, thus preventing the cooling water from affecting the steam flow. It also blocks impurities in the steam, discharging them through the drain groove at the bottom of grid plate 3 to prevent damage to the device. When the end face of piston 5 is tangent to pressure relief port 9, the steam can be discharged through pressure relief port 9 to the side of discharge seat 1 away from grid plate 3, achieving pressure relief.

[0027] A high-pressure tank 10 is provided, and a medium-pressure tank 11 and a low-pressure tank 12 are provided on the side of the high-pressure tank 10, the medium-pressure tank 11 and the low-pressure tank 12 respectively. The end of the low-pressure tank 12 is connected to a discharge port 13. A pressure gauge 14 is provided at the top of the high-pressure tank 10. A drain pipe 15 is connected to the bottom of the high-pressure tank 10. A drain valve 16 is provided inside the drain pipe 15. There are three pressure gauges 14, drain pipes 15 and drain valves 16, which are provided at the bottom of the high-pressure tank 10, the medium-pressure tank 11 and the low-pressure tank 12. The pressure gauges 14 and drain valves 16 are connected to the controller 8 by wires.

[0028] Specifically, the three discharge seats 1 are connected to the high-pressure tank 10, the medium-pressure tank 11, and the low-pressure tank 12 respectively at the ends away from the grid plate 3. This allows steam to be discharged to the high-pressure tank 10, the medium-pressure tank 11, and the low-pressure tank 12 in stages, thereby gradually depressurizing and cooling the steam. The pressure gauge 14 can detect the internal pressure of the high-pressure tank 10, the medium-pressure tank 11, and the low-pressure tank 12 to ensure the stability of the device operation. The controller 8 can also control the drain valve 16 to drain the water accumulated inside the high-pressure tank 10, the medium-pressure tank 11, and the low-pressure tank 12 through the drain pipe 15.

[0029] Working Principle: In this structure, steam is introduced into the discharge seat 1 through steam port 2. The steam, through its own pressure, pushes piston 5 to slide, resisting the sliding of spring 6. When piston 5 is tangential to pressure relief port 9, the pressure of spring 6 on pressure sensor 7 reaches a predetermined value, which transmits a signal to controller 8. This activates water injection pipe 4 to inject cooling water into grid plate 3, allowing the cooling water to flow on the surface of grid plate 3. This ensures that the steam can fully contact the cooling water, rapidly cooling the steam. It also prevents a large amount of cooling water from being washed away, preventing the cooling water from affecting the steam flow, and blocking impurities in the steam, which are then discharged through the drain groove at the bottom of grid plate 3, preventing them from affecting the equipment. If damage is caused, the piston 5 end face is tangent to the pressure relief port 9, and the steam can be discharged through the pressure relief port 9 to the side of the discharge seat 1 away from the grid plate 3 to achieve pressure relief. The ends of the three discharge seats 1 away from the grid plate 3 are respectively connected to the high pressure tank 10, the medium pressure tank 11 and the low pressure tank 12, which can discharge the steam to the high pressure tank 10, the medium pressure tank 11 and the low pressure tank 12 in stages, so as to gradually relieve the pressure and cool down the steam. The pressure gauge 14 can detect the internal pressure of the high pressure tank 10, the medium pressure tank 11 and the low pressure tank 12 to ensure the stability of the device operation. The controller 8 can also control the drain valve 16 to drain the water accumulated inside the high pressure tank 10, the medium pressure tank 11 and the low pressure tank 12 through the drain pipe 15.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
