Description

Technical Field

[0001] This application relates to the field of valve commissioning device technology, and specifically discloses a fully enclosed high-pressure valve commissioning device. Background Technology

[0002] A fully enclosed high-pressure valve is an overpressure protection device used in high-pressure equipment or pipelines. It achieves automatic pressure relief through the dynamic balance between spring force and medium pressure. Combined with nozzle structure and thermoelastic valve disc design, it ensures efficient discharge and reliable sealing. Its core features lie in precise mechanical adjustment and the selection of durable materials, making it suitable for safety protection in high-pressure, high-temperature, or corrosive environments. Under the action of spring force, the valve disc is tightly pressed against the valve seat sealing surface, completely sealing the system medium. When the system pressure rises to the set pressure, the upward thrust of the medium on the valve disc overcomes the spring preload, causing the valve disc to disengage from the valve seat and the valve to open. Traditional fully enclosed high-pressure valve commissioning essentially involves adjusting the effective number of spring coils, thereby changing the elastic force. In other words, the effective number of spring coils is changed by stretching and compressing the spring. Existing commissioning devices can only roughly adjust the starting pressure of fully enclosed high-pressure valves and cannot precisely adjust to the specific starting pressure. In view of this, this utility model provides a fully enclosed high-pressure valve commissioning device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem that traditional high-pressure valve debugging devices cannot accurately adjust to the starting pressure of high-pressure valves.

[0004] To achieve the above objectives, this utility model provides the following basic solution: A fully enclosed high-pressure valve debugging device includes a debugging assembly detachably connected to the high-pressure valve body. The debugging assembly includes a bottom stabilizer, a support on the bottom stabilizer, and a mounting plate on the support. A spring adjusting rod in the high-pressure valve body is located at the top of the valve body. The spring adjusting rod is equipped with a scale and a locking plate. A distance sensor receiving target and a distance sensor transmitter are respectively provided on the mounting plate and the locking plate. The device also includes a fixture for fixing the position of the spring adjusting rod and a digital display for digitizing the distance between the distance sensor receiving target and the distance sensor transmitter.

[0005] Furthermore, the high-pressure valve body is placed vertically, with one end of the high-pressure valve body being a liquid inlet and the other end being a spring adjustment rod mounting area. One side of the high-pressure valve body is a liquid outlet, and a baffle plate is provided inside the high-pressure valve body between the liquid inlet and the liquid outlet.

[0006] Furthermore, the high-pressure valve body includes a main pipe, a main flange installed at the bottom of the main pipe for connecting to the liquid inlet, a secondary pipe disposed on one side of the main pipe and communicating with the main pipe, a secondary flange fixed to the secondary pipe for connecting to the liquid outlet, a connecting flange disposed at the other end of the main pipe and connected by connecting bolts, an mounting sleeve mounted on the connecting flange and having an inner diameter equal to the inner diameter of the main pipe, and a top component fixed to the end of the mounting sleeve.

[0007] Furthermore, a spring is provided inside the main tube and the mounting cylinder. One end of the spring is fixedly connected to the blocking plate, and the other end of the spring is connected to the spring adjusting rod. The spring adjusting rod includes a pressing plate and an adjusting rod that are slidably placed inside the mounting cylinder. One end of the adjusting rod is in contact with the pressing plate, and the other end of the adjusting rod protrudes through the top component.

[0008] Furthermore, when the spring is in its normal state, the end of the baffle plate is flush with the end face of the main pipe near the liquid inlet, and the main pipe and the auxiliary pipe are not connected at this time.

[0009] Furthermore, the size of the card plate is larger than the size of the adjusting pressure rod, and the card plate has a mounting slot for placing the distance sensor transmitter. Both the distance sensor transmitter and the distance sensor receiving target are located on the center line of the adjusting pressure rod.

[0010] Furthermore, the top component has a through groove, the adjusting pressure rod passes through the through groove, and threaded grooves are formed on the top component on both sides of the through groove. The clamping plate has a connecting hole at the position corresponding to the threaded groove, and the fixing device is a connecting screw. The connecting screw is threadedly connected to the threaded groove through the connecting hole.

[0011] Furthermore, it also includes an adjusting pressure rod protective sleeve, and a connecting groove is provided on the outer periphery of the top component, the adjusting pressure rod protective sleeve being connected to the connecting groove.

[0012] The principle and effect of this solution are as follows: 1. Compared with existing technologies, this device has a simple structure and ingenious design. The main users of this device are owners, meaning that the high-pressure valve body does not need to be returned to the factory for debugging. Owners can also debug it themselves. The core is that a scale is set on the spring adjustment rod. The change of the scale directly reflects the pressure, thereby controlling the opening pressure of the high-pressure valve body. This scale directly and precisely measures the opening pressure, solving the problem that traditional high-pressure valve debugging devices cannot accurately adjust the starting pressure of the high-pressure valve.

[0013] 2. Compared with the prior art, this application mainly involves debugging and anchoring at the manufacturer. A debugging component is set up. The essence of the debugging component is to measure the change in the spring adjusting rod, thereby determining the actual opening pressure of the high-pressure valve body. The change in the ...

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] The reference numerals in the accompanying drawings include: high-pressure valve body 1, main pipe 101, main flange 102, secondary pipe 103, secondary flange 104, connecting flange 105, mounting sleeve 106, top component 107, connecting groove 108, adjusting rod 109, clamping plate 110, connecting bolt 111, blocking plate 112, first clamp 2, second clamp 3, clamp connector 4, adjusting rod protective sleeve 5, mounting plate 6, support component 7, threaded groove 8, connecting screw 9, distance sensor receiving target 10, and distance sensor transmitter 11.

[0018] Implementation, for example Figure 1 , Figure 2 and Figure 3 As shown: A fully enclosed high-pressure valve debugging device includes a debugging assembly detachably connected to the high-pressure valve body 1. The debugging assembly includes a bottom stabilizer, a support 7 mounted on the bottom stabilizer, and a mounting plate 6 mounted on the support 7. A spring adjusting rod 109 in the high-pressure valve body 1 is located on the top of the high-pressure valve body 1. The spring adjusting rod 109 is provided with a scale and a clamping plate 110. A distance sensor receiving target 10 and a distance sensor transmitter 11 are respectively provided on the mounting plate 6 and the clamping plate 110. The device also includes a fixture for fixing the position of the spring adjusting rod 109 and a digital display for digitizing the distance between the distance sensor receiving target 10 and the distance sensor transmitter 11.

[0019] First, let's introduce the high-pressure valve body 1: like Figure 1 As shown, the high-pressure valve body 1 is placed vertically. One end of the high-pressure valve body 1 is a liquid inlet, through which water flows at a predetermined pressure. The other end of the high-pressure valve body 1 is the installation area for the spring adjusting rod 109. One side of the high-pressure valve body 1 is a liquid outlet, through which water flows out. A baffle plate 112 is installed inside the high-pressure valve body 1 between the liquid inlet and the liquid outlet. If the baffle plate 112 does not move upward, the high-pressure valve body 1 is closed, and water cannot flow out of the liquid outlet. Conversely, if the baffle plate 112 moves upward, the high-pressure valve body 1 is open, and water flows out of the liquid outlet. The high-pressure valve body 1 includes a main pipe 101, a main flange 102 installed at the bottom of the main pipe 101 for connecting to the liquid inlet, a secondary pipe 103 located on one side of the main pipe 101 and communicating with the main pipe 101, a secondary flange 104 fixed to the secondary pipe 103 for connecting to the liquid outlet, a connecting flange 105 located at the other end of the main pipe 101 and connected by connecting bolts 111, a mounting sleeve 106 installed on the connecting flange 105 and having an inner diameter equal to the inner diameter of the main pipe 101, and a top component 107 fixed to the end of the mounting sleeve 106.

[0020] Regarding the manufacturer's commissioning phase: The debugging component needs to be used. Before using the debugging component, the spring is in the normal state, and the end of the baffle plate 112 is flush with the end face of the main pipe 101 near the liquid inlet. At this time, the main pipe 101 and the secondary pipe 103 are not connected.

[0021] The liquid inlet outputs a water flow at a predetermined pressure, which results in the opening pressure of the high-pressure valve body 1 when the spring is in a normal state. The opening pressure of all high-pressure valve bodies 1 should be consistent, that is, standardized production for the manufacturer. Then, the core is that the spring adjusting rod 109 is equipped with a scale, and the scale is anchored to the pressure value. First, regarding the spring force, the spring coefficient k is inversely proportional to the effective number of coils n. By compressing the spring or cutting off part of the coil, the spring force can be increased, and the spring can be stretched to increase the number of coils and decrease the spring force. Therefore, based on this principle, the traditional high-pressure valve body 1 is equipped with a spring adjusting rod 109 inside. Specifically: A spring is provided inside the main tube 101 and the mounting cylinder 106. One end of the spring is fixed to the blocking plate 112, and the other end of the spring is connected to the spring adjusting rod 109. The spring adjusting rod 109 includes a pressing plate that is slidably placed inside the mounting cylinder 106 and an adjusting rod 109. One end of the adjusting rod 109 is in contact with the pressing plate, and the other end of the adjusting rod 109 protrudes out of the top component 107.

[0022] By squeezing or compressing the upper end of the spring with a squeezing plate, the effective number of coils at the upper end of the spring is changed, thereby changing the elastic force. For manufacturers, after obtaining the standard opening pressure, the next step is to install and debug the components. The bottom stabilizing components are a first clamp 2 and a second clamp 3. The first clamp 2 and the second clamp 3 are connected in a circle on the mounting cylinder 106 by a clamp connector 4. Then, the upper ends of the first clamp 2 and the second clamp 3 are used to install the support component 7. After the support component 7 is installed, the mounting plate 6 is installed through the support component 7. After the mounting plate 6 is installed, the distance sensor receiving target 10 and the distance sensor transmitter 11 are installed. The size of the clamp plate 110 is larger than the size of the adjusting rod 109 to prevent the adjusting rod 109 from sliding out excessively. The clamp plate 110 has a mounting groove for placing the distance sensor transmitter 11. The distance sensor transmitter 11 and the distance sensor receiving target 10 are both located on the center line of the adjusting rod 109.

[0023] Manually press or pull the adjusting lever 109 to move it up and down. At this time, the digital display shows the change in distance. Taking pressing the adjusting lever 109 as an example, the spring force can be increased by compressing the spring (such as by clamping it with a tool) or cutting off part of the coil. Then the pressure of the liquid inlet is gradually increased. Then check if the liquid outlet is open. If water is coming out of the liquid outlet, stop gradually increasing the pressure of the liquid inlet. At this time, the compression of the adjusting lever 109 is already anchored to the increased pressure. Conversely, the same principle applies to adjusting lever 109; After obtaining a large amount of debugging data, the manufacturer directly remanufactured the adjusting rod 109 and anchored the scale on the adjusting rod 109 directly to the increased pressure height. That is, by adjusting the scale and changing the position of the adjusting rod 109, the pressure can be increased or decreased. This pressure is known. The top component 107 has a through groove, and the adjusting pressure rod 109 passes through the through groove. Threaded grooves 8 are formed on the top component 107 on both sides of the through groove. The clamping plate 110 has a connecting hole corresponding to the threaded groove 8. The fixing device is a connecting screw 9, and the connecting screw 9 is threadedly connected to the threaded groove 8 through the connecting hole. Since the core of this application is the adjusting lever 109, the adjusting lever 109 is not allowed to be used by private individuals at will. Therefore, it also includes an adjusting lever protective sleeve 5. A connecting groove 108 is provided on the outer periphery of the top component 107. The adjusting lever protective sleeve 5 is connected to the connecting groove 108 to protect the adjusting lever 109. Similarly, if the device is installed in a location with high population flow, the adjusting lever protective sleeve 5 can be magnetically connected to the connecting groove 108, and then a demagnetizing lock is set. The adjusting lever protective sleeve 5 can only be opened after the magnetism is lost.

[0024] This device solves the problem that traditional high-pressure valve commissioning devices cannot accurately adjust to the starting pressure of high-pressure valves.
