Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and in particular to a shock-absorbing butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is characterized by a disc-shaped closing element (valve disc or butterfly plate) that rotates around a valve shaft to open and close. These valves can control the flow of various types of fluids, including air, water, steam, corrosive media, mud, oil, liquid metals, and radioactive media. They primarily function as shut-off and throttling devices in pipelines. The butterfly valve's opening and closing element is a disc-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation.

[0003] Chinese Patent No. CN219866576U discloses a shock-absorbing butterfly valve, including a butterfly valve body. Inside the butterfly valve body is a valve plate, and a valve stem is fixedly connected to the top of the valve plate. The top of the valve stem penetrates the butterfly valve body and is fixedly connected to a fixing disc. Two support rods are fixedly connected to the upper surface of the butterfly valve body, and a fixing ring is fixedly connected to the top of each support rod. Multiple limiting grooves are arranged in a ring array on the outer side of the fixing ring. A fixing plate is fixedly connected to the top of the fixing disc, and a rectangular hole is formed on the fixing plate. A matching moving block is slidably connected inside the rectangular hole, and a second spring is symmetrically arranged inside the rectangular hole. This application solves the problem that some existing butterfly valves have poor fixing effects, allowing the handle to rotate freely when accidentally touched by external force, thus adjusting the butterfly valve and causing unexpected situations. However, the aforementioned patent still has certain defects. It uses a first spring to provide shock absorption protection for the butterfly valve body, but the shock absorption protection of a single first spring is not effective, affecting the service life and safety of the butterfly valve. Therefore, we propose a shock-absorbing butterfly valve to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing butterfly valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shock-absorbing butterfly valve includes a shock-absorbing assembly. The shock-absorbing assembly includes a mounting housing. Two slide rods are connected to the inner wall of the mounting housing. Two U-shaped fixing brackets are slidably connected to the outer surfaces of the two slide rods. Two mounting seats are connected to one side of each U-shaped fixing bracket. A movable plate is hinged to the side of each set of mounting seats that are close to each other via a first pin. A U-shaped connecting plate is provided above the mounting housing. The outer surface of each movable plate is hinged to the inner wall of the U-shaped connecting plate via a second pin. A damper is connected to one side of the U-shaped connecting plate. One end of the damper is connected to the inner bottom wall of the mounting housing. Two telescopic springs are sleeved on the outer surface of each slide rod. A butterfly valve housing is mounted on one side of the U-shaped connecting plate.

[0007] In a further embodiment, the outer surface of the butterfly valve housing is connected to two flanges, and each flange has a set of fixing holes on one side.

[0008] In a further embodiment, the outer surface of the U-shaped connecting plate is connected to two reinforcing blocks, and the outer surface of each reinforcing block is connected to the outer surface of the butterfly valve housing.

[0009] In a further embodiment, the inner wall of the mounting housing has two sliding grooves, and each sliding groove has a sliding block slidably connected to its inner wall. The side of each set of sliding blocks that is close to each other is connected to the outer surface of the U-shaped fixing frame.

[0010] In a further embodiment, each of the telescopic springs is located on the opposite side of the two U-shaped brackets, with the end of each set of telescopic springs that is close to each other connected to the outer surface of the U-shaped bracket, and the end of each set of telescopic springs that is far from each other connected to the inner wall of the mounting housing.

[0011] In a further embodiment, two support frames are connected to one side of the mounting housing, and each support frame has two mounting holes on one side.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device is slidably connected to the U-shaped fixed frame via a sliding rod. The rebound force of the telescopic spring and the auxiliary control force of the damper allow the U-shaped fixed frame to move slightly left and right. In conjunction with the first and second pins, as well as the use of the mounting base and U-shaped connecting plate, it can easily provide shock absorption and protection for the butterfly valve body, preventing damage to the butterfly valve body due to high-intensity vibration. It can also increase the service life and safety of the butterfly valve body. Attached Figure Description
