Technical Field
[0001] The utility model relates to the technical field of water supply, in particular to a water pressure control device structure for a papermaking water supply pipe. Background Art
[0002] As an important industrial sector, paper mills require a large amount of water resources in the production process. Water is a key factor in the papermaking process, involving multiple links such as raw material processing, pulp preparation, paper forming and drying.
[0003] At present, the water pressure in the water supply pipe used in papermaking production has certain fluctuations, which cannot guarantee the stability of the water supply pressure and affects papermaking production. Therefore, we propose a water pressure control device for papermaking water supply pipes. Utility Model Content
[0004] The purpose of the utility model is to provide a water pressure control device for a papermaking water supply pipe, which has the ability to automatically adjust the water pressure fluctuations in the papermaking water supply pipe to stabilize the water pressure of the water supply, which is beneficial to papermaking production and is suitable for adjusting fluctuations of different water supply pressures, thereby improving the applicability and solving the problem that the water pressure in the water supply pipe used in the current papermaking production has certain fluctuations, cannot guarantee the stability of the water supply pressure, and affects papermaking production.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water pressure control device for a papermaking water supply pipe, comprising a connecting pipe and a pressure regulating pipe, a connecting pipe welded on the upper surface of the connecting pipe, a pressure regulating pipe welded on the end of the connecting pipe, a sealing pipe cover fixedly connected to the end of the pressure regulating pipe, a fixed sleeve fixedly connected at the top axial position of the inner wall of the sealing pipe cover, a sliding rod slidably inserted inside the fixed sleeve, a spring fixedly connected to one end of the sliding rod located inside the fixed sleeve, a piston plate fixedly connected to one end of the sliding rod located outside the fixed sleeve, an exhaust valve and a one-way inflation valve fixedly connected to the two sides of the upper surface of the sealing pipe cover.
[0006] Preferably, the diameter of the communicating tube is smaller than the diameter of the pressure regulating tube, which serves to limit the piston plate and prevent the piston plate from entering the communicating tube and the connecting tube.
[0007] Preferably, connecting flanges are welded at both ends of the connecting pipe, and the connecting pipe is fixedly connected to the papermaking water supply pipe through the connecting flanges and bolts, so that the water supply required for papermaking flows through the inside of the connecting pipe.
[0008] Preferably, the end of the one-way inflation valve is fixedly connected to a quick connector, and the inflation pipe of an inflation device such as an air pump is quickly connected to the one-way inflation valve through the quick connector.
[0009] Preferably, a pressure gauge is fixedly mounted on the upper surface of the sealing tube cover near the front surface, so as to facilitate observation of the air pressure value inside the pressure regulating tube, thereby facilitating adjustment of the air pressure inside the pressure regulating tube.
[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0011] 1. The utility model is provided with a connecting pipe, a connecting pipe, a pressure regulating pipe, a sealing pipe cover, a fixed sleeve, a spring, a sliding rod and a piston plate, so as to automatically adjust the water pressure fluctuation in the papermaking water supply pipe to stabilize the water pressure of the water supply, which is beneficial to the papermaking production effect. The two ends of the connecting pipe are connected to the pipeline of the papermaking water supply pipe. When the water pressure value inside the connecting pipe increases, the piston plate moves up, the spring is compressed, and the air inside the pressure regulating pipe is compressed. Part of the water in the connecting pipe enters the pressure regulating pipe to reduce the water pressure value inside the connecting pipe. When the water pressure value inside the connecting pipe decreases, the compressed air and the compressed spring cause the piston plate to move down, and the water inside the pressure regulating pipe is replenished into the connecting pipe to increase the water pressure value inside the connecting pipe, thereby controlling the water pressure value of the water supply to be stable.
[0012] 2. The utility model achieves the effect of being applicable to fluctuation regulation of different water supply pressures by arranging an exhaust valve and a one-way inflation valve, thereby improving the applicability. An air pump or other inflatable equipment fills gas into the pressure regulating tube through the one-way inflation valve to increase the air pressure value inside the pressure regulating tube, while the gas inside the pressure regulating tube can be discharged through the exhaust valve to reduce the air pressure value inside the pressure regulating tube, so that water of different pressures flows inside the connecting tube, and when the water pressure value fluctuates, the piston plate can slide up and down inside the pressure regulating tube.
[0013] 3. The utility model provides a pressure gauge, which makes it easy to observe the air pressure value inside the pressure regulating tube, thereby facilitating the adjustment of the air pressure inside the pressure regulating tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1-4 As shown, the utility model proposes a water pressure control device for a papermaking water supply pipe, comprising a connecting pipe 2 and a pressure regulating pipe 4. Connecting flanges 3 are welded at both ends of the connecting pipe 2. The connecting pipe 2 is fixedly connected to the papermaking water supply pipe through the connecting flange 3 and bolts, so that the water supply required for papermaking flows through the inside of the connecting pipe 2. A connecting pipe 1 is welded on the upper surface of the connecting pipe 2, and a pressure regulating pipe 4 is welded at the end of the connecting pipe 1. A sealing pipe cover 5 is fixedly connected to the end of the pressure regulating pipe 4. The sealing pipe cover 5 and the pressure regulating pipe 4 are fixedly connected by bolts to facilitate the disassembly of the sealing pipe cover 5 and the inspection of the inside of the pressure regulating pipe 4. A fixed sleeve 10 is fixedly connected at the top axial position of the inner wall of the sealing pipe cover 5, and a sliding rod 12 is slidably inserted inside the fixed sleeve 10.
[0021] One end of the sliding rod 12 located inside the fixed sleeve 10 is fixedly connected to a spring 11, and the other end of the sliding rod 12 located outside the fixed sleeve 10 is fixedly connected to a piston plate 13. The diameter of the connecting pipe 1 is smaller than the diameter of the pressure regulating pipe 4, which serves to limit the piston plate 13 to prevent the piston plate 13 from entering the connecting pipe 1 and the connecting pipe 2. The exhaust valve 6 and the one-way inflation valve 9 are fixedly connected to the two sides of the upper surface of the sealing pipe cover 5, and the end of the one-way inflation valve 9 is fixedly connected to a quick connector 7. The inflation pipe of an inflatable equipment such as an air pump is quickly connected to the one-way inflation valve 9 through the quick connector 7. A pressure gauge 8 is fixedly installed on the upper surface of the sealing pipe cover 5 near the front surface. The pressure probe of the pressure gauge 8 is located inside the pressure regulating pipe 4, and the air pressure value inside the pressure regulating pipe 4 is detected by the pressure gauge 8.
[0022] When the utility model is in use, the two ends of the connecting pipe 2 are connected to the pipeline of the papermaking water supply pipe. When the water pressure value inside the connecting pipe 2 increases, the piston plate 13 moves up, the spring 11 is compressed, and the air inside the pressure regulating pipe 4 is compressed. Part of the water in the connecting pipe 2 enters the pressure regulating pipe 4 to reduce the water pressure value inside the connecting pipe 2. When the water pressure value inside the connecting pipe 2 decreases, the compressed air and the compressed spring 11 cause the piston plate 13 to move down, and the water inside the pressure regulating pipe 4 is replenished into the connecting pipe 2 to increase the pressure. The water pressure value inside the connecting pipe 2 is controlled to stabilize the water pressure value of the water supply, and the air pump and other inflatable equipment fill the pressure regulating pipe 4 with gas through the one-way inflation valve 9 to increase the air pressure value inside the pressure regulating pipe 4, and the gas inside the pressure regulating pipe 4 can be discharged through the exhaust valve 6 to reduce the air pressure value inside the pressure regulating pipe 4, so that water of different pressures flows inside the connecting pipe 2, and when the water pressure value fluctuates, the piston plate 13 can slide up and down inside the pressure regulating pipe 4 to stabilize the water pressure value of the connecting pipe 2.
[0023] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
