Description

Technical Field

[0001] The utility model belongs to the technical field of valve bodies and relates to an integrated single-seat regulating valve body. Background Technique

[0002] There is a valve core and a valve seat in the single-seat regulating valve body, which has the characteristic of small leakage. This valve has a large unbalanced force, and its allowable pressure difference is smaller than that of the double-seat valve. When the pressure difference is high and the diameter is large, it is best to be equipped with a valve positioner. By changing the connection position between the valve stem and the valve core, air-opening or air-closing can be achieved.

[0003] However, during the working process of the traditional single-seat regulating valve, excessive noise is generated. There is no suitable sound-absorbing and sound-insulating device installed, which is likely to affect the external environment. During operation, not only the vibration of the machine itself generates noise, but the water flow also generates noise, causing noise pollution. Prolonged exposure to noise is likely to affect people's emotions and physical health, and improvement is needed. Summary of the Invention

[0004] The purpose of the utility model is to provide an integrated single-seat regulating valve body to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be achieved by the following technical solutions: The integrated single-seat regulating valve body includes a valve body part, an outer cover plate, a sound-insulating cotton sleeve, a mounting flange, a pressing rod and a sound-insulating cotton pad. A sound-insulating cavity is provided in the middle position of the valve body part. A sound-insulating cotton pad is arranged inside the sound-insulating cavity. Guide liquid pipes are fixedly connected to both ends of the valve body part, and a sound-insulating cotton sleeve is sleeved outside the guide liquid pipes. One end of the guide liquid pipe is fixedly connected with a mounting flange, and a plurality of pressing rods are arranged between the mounting flange and the valve body part. A rubber seat is arranged inside the pressing rod, and the rubber seat presses on the outer surface of the sound-insulating cotton sleeve.

[0006] In the above integrated single-seat regulating valve body, an anti-slip pattern is arranged on the outer wall surface of the guide liquid pipe, and a plurality of mounting holes are arranged at the side position of the mounting flange.

[0007] In the above integrated single-seat regulating valve body, a plurality of limiting rod bodies are arranged inside the sound-insulating cavity. Limiting holes are arranged at the side position of the sound-insulating cotton pad. The limiting rod bodies are placed inside the limiting holes, and a pressing rubber sleeve is sleeved at the outer end of the limiting rod bodies.

[0008] In the above integrated single-seat regulating valve body, an outer cover plate is installed at the outer port of the sound-insulating cavity, and the outer cover plate is fixed at the outer side of the sound-insulating cavity by screws.

[0009] In the above-mentioned integrated single-seat regulating valve body, support seats are arranged at both ends of the valve body part. A pin shaft is arranged inside the support seat. One end of the pressing rod is provided with a movable head, and the movable head is movably sleeved outside the pin shaft.

[0010] In the above-mentioned integrated single-seat regulating valve body, a fixed seat is arranged inside the mounting flange. A locking bolt is arranged at the top of the fixed seat. The top of the locking bolt passes through the notch at the end of the pressing rod and is in threaded socket connection with the locking nut at the top position of the pressing rod.

[0011] Compared with the prior art, the advantages of the integrated single-seat regulating valve body of the present utility model are as follows.

[0012] This application improves the external structure of the traditional single-seat valve body. A sound insulation cavity is arranged on the outer surface of the single-seat valve body. A sound insulation cotton pad can be installed inside the sound insulation cavity, and then it is pressed tightly by the outer cover plate. In this way, the sound insulation cotton pad can reduce the noise generated by the water flow passing through the valve seat inside the valve body. This application also arranges sound insulation cotton sleeves outside the two liquid guiding pipe bodies on both sides of the valve body. The sound insulation cotton sleeves are directly sleeved outside the liquid guiding pipe bodies, and then they are pressed tightly by a plurality of pressing rods and rubber seats. The installation is simple and efficient. In this way, the sound insulation cotton sleeves can reduce the noise generated by the incoming and outgoing water flows inside the liquid guiding pipe bodies.
