Abstract
The invention relates to a butt clamp lift check valve, in particular to a butt clamp lift check valve applied to steam and air medium conveying equipment or pipelines, and belongs to the technical field of valve equipment. The butt clamp lift check valve comprises a valve body. A valve seat is arranged inside the valve body, and the upper end of the valve seat is connected with a valve plate in a supporting mode. A guide holder is arranged in an inner cavity of the valve body, and the valve plate is connected into the guide holder in a sliding mode. The guide holder is fixedly connected with a spring support. A spring is arranged between the spring support and the valve plate. A medium outlet is formed in the center of the upper portion of the valve body, and a medium inlet is formed in the center of the lower portion of the valve body. The butt clamp lift check valve is simple, compact and reasonable in structure, stable and reliable to work, resistant to abrasion and high temperatures, capable of preventing medium flow diversion in the pipeline system, reliable in sealing effect, good in scuffing resistance and long in service life.
Description
Technical field
The present invention relates to one kind is to folder lift check valve, specifically it is applied to convey setting of steam and air dielectric
On standby or pipeline to folder lift check valve, belong to valve type equipment technical field.
Background technology
In prior art, general setting valve, opening by valve on the equipment of conveying steam and air dielectric or pipeline
Open the break-make with the conveying of closing control gas medium.In some special engineering demands, need to prevent the medium in pipe-line system
Flow backwards it is therefore desirable to arrange a kind of safe and reliable check-valves.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point, thus providing one kind to folder lift check valve, Neng Goufang
Only pipe-line system medium water conservancy diversion, sealed reliable, antifraying property is good, long service life.
The technical scheme providing according to the present invention, includes valve body to folder lift check valve, it is characterized in that：It is provided with valve body
Valve seat, valve seat upper end supports and connects valve plate；It is provided with guide holder, valve plate is slidably connected in guide holder in body cavity；Guide holder
Upper fixed spring stent, is provided with spring between spring support and valve plate；Valve body central upper portion is provided with media outlet, in valve body lower portion
The heart is provided with medium entrance.
Further, spring support is provided with located cavity, and spring upper end passes through located cavity location and installation.
Further, valve plate upper surface center is provided with spring positioning boss, and lower spring end is positioned by spring positioning boss
Install.
Compared with the prior art the present invention has advantages below：
Present configuration is simple, compact, reasonable, stable and reliable in work, Wear-resistant, high-temperature resistant；It is prevented from pipe-line system medium to lead
Stream, sealed reliable, antifraying property is good, long service life.
Brief description
Fig. 1 is front view of the present invention.
Description of reference numerals：1- valve body, 2- valve seat, 3- valve plate, 4- spring support, 5- spring, 6- guide holder, 7- spring are fixed
Position boss, 8- medium entrance, 9- media outlet, 10- located cavity.
Specific embodiment
The embodiment combining in accompanying drawing is further described by the present invention below：
As shown in figure 1, the invention mainly comprises valve body 1, being provided with valve seat 2 in valve body 1, valve seat 2 upper end supports and connects valve plate 3.
It is provided with guide holder 6, valve plate 3 is slidably connected in guide holder 6 in valve body 1 inner chamber.Fixed spring stent on guide holder 6
4, it is provided with spring 5 between spring support 4 and valve plate 3.
Described spring support 4 is provided with located cavity 10, and located cavity 10 location and installation is passed through in spring 5 upper end.On valve plate 3
End face center is provided with spring positioning boss 7, and spring positioning boss 7 location and installation is passed through in spring 5 lower end.
Valve body 1 central upper portion is provided with media outlet 9, and valve body lower portion center is provided with medium entrance 8.
Operation principle of the present invention is：Operationally, when medium flows into from medium entrance, act on lower valve in the pressure of medium
Plate is opened, and flows out from media outlet.When fluid flows back from media outlet, Fluid pressure and valve plate act on valve seat, by valve plate
It is pressed on valve seat, thus cutting off flowing.
Present configuration is simple, compact, reasonable, stable and reliable in work, Wear-resistant, high-temperature resistant；It is prevented from pipe-line system intermediary
Matter water conservancy diversion, sealed reliable, antifraying property is good, long service life.
