Mechanical limiting device for angle valve

Abstract

The invention provides a mechanical limiting device for an angle valve. The mechanical limiting device comprises an angle valve connecting pipe, wherein a valve rotating switch is arranged at one end of the angle valve connecting pipe; an angle valve decoration gasket is arranged at the other end; a connector interface is arranged on one side of the angle valve connecting pipe; interface connecting threads are formed in the surface of the connector interface; a limiter support frame is arranged on the side, far from the connector interface, of the angle valve connecting pipe; a limiter screw rod is arranged in the limiter support frame; a limiter rotating knob is arranged at one end of the limiter screw rod; and a flow limiting gasket is arranged at the other end. The mechanical limiting device for the angle valve, provided by the invention, is simple in structure, scientific and reasonable; and when the connector at an interface needs to be replaced or an angle valve knob is damaged, the designed mechanical limiting device for the angle valve can limit flowing of a water pipe without turning off a main switch of the whole water pipe, so that great convenience and practicality are realized.

Description

technical field [0001] The invention relates to a mechanical limit device for an angle valve, which belongs to the technical field of angle valves. Background technique [0002] In the prior art, an angle valve is an angle globe valve, and an angle valve is similar to a spherical valve, and its structure and characteristics are modified from a spherical valve. The difference from the spherical valve is that the outlet of the angle valve is at a 90-degree right angle to the inlet. Angle valve is also called triangle valve, angle valve, angle water valve. This is because the pipe forms a 90-degree corner at the angle valve, so it is called angle valve, angle valve, and angle water valve. The valve body of the angle valve has three ports: water inlet, water volume control port and water outlet, so it is called a triangle valve. Of course, the angle valve is constantly improving. Although there are still three ports, there are also angle valves that are not angled. The angle...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a mechanical limiter for an angle valve to solve the problem that the traditional angle valve proposed in the above background technology only has the function of switching. When the knob of the angle valve is damaged , the angle valve cannot be used, and the main gate of the water pipe needs to be closed when the joint is replaced, which leads to no water in the remaining water pipes, which is inconvenient to use and has no problem with the mechanical limit device. The present invention is easy to use and easy to operate , good stability and high reliability
