Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a safety valve with anti-clogging function. Background Technology

[0002] Valves are control components in pipeline fluid transport systems. They are used to change the cross-sectional area of ​​the passage and the direction of medium flow, and have functions such as guiding, stopping, throttling, checking back, diverting or overflowing pressure relief. Valves used for fluid control range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their types and specifications are numerous.

[0003] Patent CN218063488U describes a one-piece ball valve that uses a filter plate to enable the ball valve to filter, thereby effectively filtering out solid particles and impurities mixed in with the fluid medium, preventing sedimentation, and effectively avoiding the situation where the ball is difficult to rotate. However, when the filter screen becomes clogged, it will cause blockage at the ball core, requiring timely replacement. This necessitates timely maintenance during operation, which will delay the work. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety valve with anti-clogging function, which has the advantage of anti-clogging.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety valve with anti-clogging function, comprising a valve pipe, the top of which is connected to a branch pipe, the branch pipe including a bend, the outer wall of which is connected to a horizontal pipe, the outer wall of which is provided with a second spherical shell, the top of which has a second through hole, the bottom of which has a third through hole, and the outer wall of which is connected to an inclined pipe.

[0006] The above technical solution can achieve the effect of preventing blockage. The valve pipe and the branch pipe form a structure similar to a Tesla valve. Water flows in from one side of the bend. Because air pressure exists in the branch pipe, the water will not enter the bend when the flow is unobstructed. It will continue to flow in the valve pipe. When the second ball core of the valve pipe is blocked, the water will flow through the branch pipe, thus achieving the effect of preventing blockage and avoiding delays in work. After the work is completed, maintenance can be carried out.

[0007] Preferably, the valve pipe includes a pipe body, the top outer wall of the pipe body is provided with a first connection port, and the top outer wall of the pipe body is provided with a second connection port.

[0008] The above technical solution can serve as a connection, and the first and second connection ports can be used to connect and fix the branch pipes.

[0009] Preferably, the outer wall of the tube is provided with a first spherical shell, and the top of the first spherical shell is provided with a first perforation.

[0010] The above technical solution can achieve the installation effect. The second ball core can be placed inside the first ball shell, and the upper valve stem can be passed through the first perforation.

[0011] Preferably, a valve wheel is provided at the top of the valve tube, a first ball core is fixedly connected to the bottom outer wall of the valve wheel, and a first valve seat is provided on the outer side of the first ball core.

[0012] The above technical solution can achieve the function of opening and closing, and the first ball core can control the opening of the valve.

[0013] Preferably, a lower valve stem is fixedly connected to the bottom outer wall of the first ball core, a connecting rod is fixedly connected to the bottom outer wall of the lower valve stem, and an upper valve stem is fixedly connected to the bottom outer wall of the connecting rod.

[0014] The above technical solution can achieve a linkage effect. The lower valve stem and the upper valve stem are connected by a connecting rod, which allows the first ball core and the second ball core to move in tandem.

[0015] Preferably, a second ball core is fixedly connected to the bottom outer wall of the upper valve stem, and a second valve seat is provided on the outer side of the second ball core.

[0016] The above technical solution can achieve a sealing function, and the second valve seat can fit against the surface of the second ball core, thereby achieving a seal.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The valve pipe and branch pipe form a structure similar to a Tesla valve. Water flows in from one side of the bend. Because air pressure exists in the branch pipe, the water will not enter the bend when the flow is unobstructed. Instead, it will flow continuously from the valve pipe. When the second ball core of the valve pipe is blocked, the water will flow through the branch pipe, thus preventing blockage and avoiding delays in work. After the work is completed, maintenance can be performed.

[0019] 2. The first and second connecting ports can be used to connect and fix the branch pipe. The second ball core can be placed inside the first ball shell. The upper valve stem can pass through the first through hole. Attached Figure Description
