Resistance-free check valve with energy-saving effect for power station

Abstract

The invention discloses a resistance-free check valve with an energy-saving effect for a power station. The resistance-free check valve comprises a valve body, wherein a reinforced anti-corrosion anti-sticking mechanism is fixedly connected to the inner wall of the valve body, a first mounting valve seat is fixedly connected to one side of the valve body, a second mounting valve seat is fixedly connected to the other side of the valve body, a circulation port is formed in the inner wall of the first mounting valve seat, and a positioning flange is arranged on the outer side surface of the first mounting valve seat. According to the resistance-free check valve with the energy-saving effect for the power station, a lubricating type adjustable check mechanism, the reinforced anti-corrosion anti-sticking mechanism and a multifunctional monitoring mechanism are arranged, so that fluid check operation can be conveniently and better carried out in a channel, a good lubricating effect is achieved, the resistance is almost zero, the use strength of the device can be improved, the service life of the device can be prolonged, the anti-corrosion effect is excellent, the internal use condition can be conveniently monitored, the use function of the device is increased, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of check valves, in particular to an energy-saving non-resistance check valve for power stations. Background technique [0002] Non-resistance check valve is a kind of supporting equipment for cutting off pipelines in power stations. Valves, special valves for power stations will be used in power stations. They are suitable for the pipelines of various systems in thermal power stations. They are used to cut off or connect pipeline media. They are more temperature-resistant and pressure-resistant than ordinary valves. , People have higher and higher requirements for the manufacturing process of non-resistance check valves. [0003] The existing non-resistance check valve has certain disadvantages in use. First of all, when in use, the operation of the check valve is relatively troublesome, the lubrication effect is poor, and there is a certain resistance when moving, which is not conducive to people's movement. In ad...

Problems solved by technology

[0003] The existing non-resistance check valve has certain disadvantages in use. First of all, when in use, the operation of the check valve is relatively troublesome, the lubrication effect is poor, and there is a certain resistance when moving, which is not conducive to people's movement. In addition, it cannot be well protected during use, the use strength is poor, the use function is less, and the structure is single, which brings certain adverse effects to people's use process. For this reason, we propose a Energy-saving non-resistance check valve for power station
