A magnetic control one-way throttle valve

Abstract

The invention relates to a magnetic control one-way throttle valve connected to the downstream portion of a glass straight through connection pipe. The magnetic control one-way throttle valve comprises a valve body connected with the glass straight through connection pipe through a polytetrafluoroethylene connection piece, an iron valve element arranged in the valve body, and a strong permanent magnetic ring arranged outside the valve body in a sleeving manner, wherein the top shape of the strong permanent magnetic ring is matched with the shape of an opening of the polytetrafluoroethylene connection piece. Compared with the prior art, by moving the strong permanent magnetic ring, arranged on the glass valve body in a sleeving manner, in a manual or mechanical arm pushing manner, the aim of changing the flowing speed of fluid is achieved; due to the design of the bullet-shaped valve element, the leakproofness and the backflushing prevention property of the valve are ensured; by means of the independent part structure, the device can be small and can also be large; the lower end of the valve element is in a concave shape, continuous water scattering teeth are arranged around the edge, and therefore the turbulence scale is reduced, and the fluid can smoothly pass through; and the magnetic control one-way throttle valve has the beneficial effects of being resistant to corrosion, simple in structure, capable of being detached, low in fault rate and the like.

Description

technical field [0001] The invention relates to a throttle valve device, in particular to a magnetically controlled one-way throttle valve. Background technique [0002] In fluid control process, throttling devices are widely used to change fluid flow. Its working principle is to change the fluid pressure potential energy by changing the throttling cross-sectional area or throttling length, so as to control the fluid flow rate. Commonly used throttle valves are mechanical and electromagnetic. However, the existing throttling valve technology has complex structure and high cost, and the sealing surface or electromagnetic coil is easy to corrode, and the sealing performance is poor. Existing throttling valves generally require the control part of the throttling device to perform multi-dimensional linear or rotary motion to achieve flow regulation, so its diameter cannot be small, which limits the miniaturization of the valve body.

AI Technical Summary

Problems solved by technology

However, this device does not have the throttling function of changing the fluid flow at all. Since the solenoid valve is only designed for titration, the valve body cannot be completely disassembled, and the valve core cannot be taken out for cleaning. The device also does not have the anti-recoil required by some industrial throttle valves. Function
