Abstract
The invention provides a diaphragm valve applicable to high-temperature and low-temperature environments. The diaphragm valve comprises an upper valve body and a lower valve body, wherein the upper valve body is internally provided with a valve rod; a fluid inlet and a fluid outlet are formed in the lower part of the lower valve body; a valve plate is welded on the lower valve body. According to the diaphragm valve applicable to the high-temperature and low-temperature environments, provided by the invention, a diaphragm and the valve bodies are brazed and sealed through adopting a metal material and the structure of the valve is improved; the sealing performance and high-temperature and low-temperature resisting performance of the valve are improved.
Description
Technical field
The present invention relates to valve technology field, more particularly, to a kind of diaphragm valve.
Background technology
Traditional diaphragm valve, is sealed by encapsulant between barrier film and valve body, and encapsulant is mostly using industry
Fluid sealant and polyfluoroprene etc., sealing reliability is poor, and high temperature resistant, poor performance at low temperatures.
Content of the invention
For the problems referred to above overcoming conventional membrane valve to exist, the invention provides a kind of be applied under high and low temperature environment
Diaphragm valve.
A kind of present invention the technical scheme is that diaphragm valve being applied to high and low temperature environment for achieving the above object,
Including upper valve body 3 and lower valve body 5, in upper valve body 3, it is provided with valve rod 1, lower valve body 5 bottom is provided with fluid inlet 6 and fluid issuing 7,
Valve plate 2 is welded in lower valve body 5.
The diaphragm valve being applied to high and low temperature environment of the present invention, adopts metal material sealed with brazing between barrier film and valve body,
Improve the construction of valve, improve sealing property and the high- and low-temperature resistance performance of valve.
Brief description
Fig. 1 is the diaphragm valve main view profile that the present invention is applied to high and low temperature environment.
In figure: 1, valve rod, 2, valve plate, 3, upper valve body, 4, welding position, 5, lower valve body, 6, fluid inlet, 7, fluid goes out
Mouthful.
Specific embodiment
The diaphragm valve structure being applied to high and low temperature environment of the present invention as shown in figure 1, including upper valve body 3 and lower valve body 5, on
It is provided with valve rod 1, lower valve body 5 bottom is provided with fluid inlet 6 and fluid issuing 7, valve plate 2(barrier film in valve body 3) it is welded in lower valve body 5
On.
Barrier film is welded together by the present invention with valve body, using particulate metal material sealed with brazing, make valve closed type, can
Significantly improve by property, use environment temperature range also can be substantially improved.
The present invention is described by embodiment, and those skilled in the art know, in the spirit without departing from the present invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, the religion in the present invention
Lead down, these features and embodiment can be modified with the essence adapting to particular situation and material without departing from the present invention
God and scope.Therefore, the present invention is not limited to the particular embodiment disclosed, fallen with claims hereof
In the range of embodiment broadly fall into protection scope of the present invention.
