Problems solved by technology

[0003] It can be seen that even though the most wear-resistant ceramic valve is used, the problem of abrasion of the valve by highly abrasive materials cannot be solved. At the same time, the solid matter in the medium will be blocked

Embodiment Construction

[0024] Such as Figure 1-5 As shown, a super wear-resistant control valve described in the embodiment of the present invention mainly includes a valve body 1, a valve core 2 and an actuator 3, the valve body mainly includes a valve cavity 4 and a medium flow channel 5, and the valve core 2 is placed In the valve cavity 4, the actuator 3 is connected with the valve core 2 and controls the rotation of the valve core 2. The valve core 2 is provided with a sealing body 6 and an adjusting body 7. The sealing body 6 and the adjusting body 7 are arranged separately. When the valve core 2 rotates, The sealing body 6 can be used to seal the medium flow channel 5, and the regulating body 7 can be used to regulate the flow rate of the medium in the medium flow channel 5. The thickness of 12 is greater than the thickness of the tungsten carbide coating 12 on the sealing body, so that the abrasion resistance of the adjusting body 7 is higher than that of the sealing body 6 .

Abstract

The invention discloses an ultra-wear-resistant control valve, which mainly comprises a valve body, a valve core and a control mechanism. The valve body mainly comprises a valve cavity and a medium passage. The valve core is arranged in the valve cavity; an actuating mechanism is connected with the valve core, and is used for controlling the valve core to rotate; the valve core is provided with a sealing member and a regulating body; the sealing member and the regulating body are arranged separately; the sealing member can be used for sealing the medium passage; the regulating body can be used for regulating the flow of a medium in the medium passage. According to the ultra-wear-resistant control valve disclosed by the invention, by performing structural decomposition on an on-off function and a flow regulating function of a traditional valve, the wear-resistant property of the regulating body is higher than that of the sealing member; the sealing performance of the sealing member cannot be influenced by the impact and the wear of the medium to the regulating body. Meanwhile, by adding a scavenging function, the phenomenon that the valve is damaged due to the fact that a solid material is deposited in the valve cavity is completely eradicated, and therefore, the service life of the valve is greatly prolonged.

Description

technical field [0001] The invention relates to the field of fluid valves, in particular to a super wear-resistant control valve. Background technique [0002] At present, the valves commonly used in industrial pipelines and non-industrial pipelines at home and abroad mainly include gate valves, globe valves, throttle valves, ball valves, butterfly valves, plug valves, etc. Among them, whether it is a valve with switch function or a valve with both switch function and flow adjustment function, the switch or flow adjustment function is realized by changing the relative position of the valve core and valve seat. The degree of wear in the adjustment process is much greater than that in the switching process, and the worn part is just the part used for sealing. After the wear reaches a certain level, the sealing will lose its function, and the valve will be scrapped. The wear degree of the regulating valve used for abrasive media is particularly large, so its life is shorter. A...
