Problems solved by technology

After a long time of use, impurities will enter between the valve core and the seal, causing wear between the valve core and the seal. When the wear reaches a certain level, the seal will fail, resulting in leakage of the ball valve.

Embodiment

[0030] Embodiment: A diamond material of the present invention, the diamond composite material is prepared by the following weight components, 90-110 parts of diamond particles, 12-20 parts of nickel-chromium alloy powder, and 4-6 parts of binder;

[0031] The diamond composite material is prepared by the following steps:

[0032] Step 1: Ultrasonic treatment of diamond particles, and cleaning;

[0033] Step 2: add the binder to the cleaned diamond particles and mix well, then add nickel-chromium alloy powder for stirring, and then place them at a temperature of 200-250°C for 1-2 hours to obtain pretreated diamond particles ;

[0034] Step 3: Grinding the pretreated diamond particles with ultra-micro processing equipment to obtain a powdered diamond composite material. The diamond particles and the nickel-chromium alloy powder are bonded and mixed through a binder, and then pulverized to obtain a powdery diamond composite material, so that the obtained powder diamond composi...

Abstract

The diamond material and diamond composite material ball valve comprises a valve body and a spherical valve element, a valve cavity is formed in the valve body, a first rough surface is arranged on the surface of an inner cavity of the valve cavity, a second rough surface is arranged on the surface of the spherical valve element, a first diamond composite layer is arranged on the first rough surface, and a second diamond composite layer is arranged on the second rough surface. A second diamond composite layer is arranged on the second rough surface, a vertically upward valve rod penetrating through the valve body is arranged on the spherical valve element, and a positive pressure sealing mechanism is arranged between the valve body and the valve rod; the inner wall of the valve cavity is provided with an inflation sealing mechanism for sealing the joint of the valve body and the valve cavity. According to the invention, the wear resistance and corrosion resistance of the valve cavity are effectively improved, so that the service life of the valve body is prolonged, the leakage phenomenon between the valve cavity and the spherical valve core is avoided, and meanwhile, the production precision requirements of the valve cavity and the spherical valve core are reduced.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a diamond material and diamond composite material ball valve. Background technique [0002] The ball valve is sealed by the cooperation of the seal installed in the valve body and the spherical valve core. Depending on the environment in which the ball valve is used, the valve core is usually made of ordinary steel or stainless steel. During the use of the ball valve, problems such as leakage often occur. Through research, it is found that one of the main reasons for the leakage of the ball valve is that when the ball valve is closed, the valve core will be exposed at the liquid inlet and outlet of the seal. For reasons such as impurities or chemical corrosion, a rust layer or some impurities will be formed on the two opposite exposed surfaces of the valve core. After a long time of use, impurities will enter between the valve core and the seal, causing wear between the val...
