Problems solved by technology

In the production process of chemical reagents, the amount of added materials must be strictly controlled, and the adjustment of the valve body has high precision requirements. However, the current manual valve stem is connected to the valve body with ordinary threads. Due to wear, the fit becomes loose, seriously affecting the adjustment accuracy of the valve body

Abstract

The present invention relates to the liquid delivery valve field, and discloses a rolling ball screw-type valve body. The rolling ball screw-type valve body comprises a valve body, a valve rod and a valve core, wherein the valve body is provided with a water inlet and a water outlet, the water inlet and the water outlet are separated by the valve core, the valve core is connected at a lower end of the valve rod, the valve rod is disposed inside the valve body in a penetrating manner, rolling balls are disposed among screw teeth of the valve rod, and the valve body is provided with an outline matched in a rolling manner with the rolling balls and is provided with a rolling ball passage. According to the rolling ball screw-type valve body, sliding friction is changed into rolling friction, frictional resistance is greatly reduced, screwed transmission conditions are improved, abrasion is also reduced, and the service life is prolonged.

Description

technical field [0001] The present invention relates to the field of liquid delivery valves. Background technique [0002] Manual valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, regulation, throttling, check, diversion or overflow pressure relief. For fluid control valves, the nominal diameter of the valve ranges from very small instrument valves to industrial pipeline valves with a diameter of up to 10m. Under the action of pressure, temperature or other forms of sensing signals, the valve can act according to the predetermined requirements, or simply open or close without relying on the sensing signal. The valve relies on the driving or automatic mechanism to make the opening and closing parts lift and slide , pendulum or rotary motion, thereby changing the size of its flow channel area to realize its control function. The traditional manua...
