Problems solved by technology

[0003] However, in many cases, the temperature and pressure of the gas or liquid are quite high, such environmental conditions will cause severe deformation of the gasket made of rubber or plastic, once the gasket is deformed, it cannot completely seal the gap between the baffle and the housing, Even cause the gasket to fall off, causing the leakage of gas or liquid
[0004] Furthermore, gaskets made of rubber or plastic may also deteriorate due to high temperature and pressure or strong acid and alkali, and the materials of the deteriorated gaskets will mix with gas or liquid, causing gas or liquid to be polluted

Embodiment Construction

[0031] The following examples illustrate possible implementations of the present invention, but they are not intended to limit the protection scope of the present invention and are described in advance.

[0032] First, see Figure 1 to Figure 3 , The flow controller of the present invention includes a housing 10 , a first support member 20 , a second support member 30 , a drive shaft 40 , a support shaft 50 , three bushings 60 and an elliptical valve 70 .

[0033] The casing 10 is made of metal material, the casing 10 has an inner ring wall 11 and an outer ring wall 12, the inner ring wall 11 encloses a channel 111 with a circular cross section, and the casing 10 defines a first A through hole and a second through hole, the first and second through holes respectively pass through the inner and outer ring walls 11, 12 of the housing 10 and communicate with the channel 111, the first and second through holes are mutually axis. In addition, the ends of the casing 10 on both sid...

Abstract

The invention provides a flow controller. The flow controller comprises a case, a first support piece, a driving shaft and an oval valve, wherein the case is provided with a channel; the first support piece is arranged on the case; the driving shaft is arranged on the first support piece; the oval valve is arranged on the channel and connected to the driving shaft; the driving shaft drives the oval valve to rotate to open and close the channel. Thus, when the oval valve closes the channel, the oval valve is in close fit with the inner ring wall of the case thoroughly to completely close the channel, and the flow controller is applied to high-temperature high-pressure environments.

Description

technical field [0001] The invention relates to the field of a flow controller; in particular, it relates to a flow controller which uses its elliptical valve opening and closing channel to control the flow of gas or liquid. Background technique [0002] Butterfly valves are widely used in industrial and commercial activities. Products such as butterfly valves are usually provided with a rubber or plastic gasket around the baffle, such as those disclosed in patent cases such as Taiwan 099060, 142009, 200949108 and I292018, to achieve a leak-proof effect. [0003] However, in many cases, the temperature and pressure of the gas or liquid are quite high, such environmental conditions will cause severe deformation of the gasket made of rubber or plastic, once the gasket is deformed, it cannot completely seal the gap between the baffle and the housing, It may even cause the gasket to fall off, causing the leakage of gas or liquid. [0004] Furthermore, gaskets made of rubber or...
