Problems solved by technology

As the core component of the fracturing flowback equipment, the throttle valve plays a vital role. Whether the throttle valve can work normally is related to the normal operation of the entire equipment. However, when the existing throttle valve is used, When the fluid enters the valve body, it will directly impact the inside of the valve body, causing serious erosion of the throttle valve, affecting the service life of the valve body, and making a lot of noise during use

Abstract

The invention discloses a puncture-corrosion-resistant sealable zero throttling valve. The valve comprises a valve body, a bonnet is mounted at one end of the valve body, a valve seat is arranged in the valve body, a lining is arranged in the end, located at the valve seat, of the valve body, one end of the bonnet extends into an annular cavity in the valve body, and a fluid inlet of the valve body is located in the side surface of the part, extending into the valve body, of the bonnet; a plunger is arranged at the end, located in the valve body, of the bonnet in a penetrating mode, a connecting rod is arranged in the plunger in a penetrating mode, a valve rod is arranged at the end, located outside the valve body, of the bonnet, and one end of the plunger is nested in the valve rod. The invention is applicable to the throttling valve. After the fluid enters the annular cavity in the valve body, the fluid is blocked by the extending part of the bonnet, the direction of the fluid is changed, the fluid is impacted, the energy of the fluid is consumed, the impact energy of the fluid on the valve body is also consumed, the erosion of the fluid to the interior of the throttling valve is reduced, the noise is reduced, and the effects that the valve is resistant to puncture corrosion and zero sealing can be achieved when the valve is fully closed are achieved.

Description

technical field [0001] The invention belongs to the technical field of natural gas exploitation, in particular to a piercing-resistant and zero-sealable throttle valve. Background technique [0002] The main component of natural gas is methane (CH4). As a clean energy source, methane is mainly composed of water and carbon dioxide after combustion. Therefore, compared with traditional coal and oil, it is clean and pollution-free, and has little impact on the environment. Natural gas is used as energy It is beneficial to protect the environment. At the same time, natural gas is convenient to transport and can be transported long distances through pipelines. In recent years, with the increasing domestic demand for natural gas, the scale of shale gas exploitation has also increased; [0003] The throttle valve is mainly used to adjust the pressure and flow, and it is an indispensable equipment in the fracturing flowback equipment. As the core component of the fracturing flowbac...
