Drawings
FIG. 1 is a schematic structural view of a forged steel check valve according to an embodiment of the present invention.
Detailed Description
The embodiments of the utility model will be further described with reference to the accompanying drawings in which:
as shown in the figure, the forged steel check valve comprises a left valve body 1, a right valve body 2, a valve clack 3, a valve rod 4 and a spring 5.
An inlet channel 11 is formed on the left side of the left valve body 1, a valve cavity 12 is formed on the right side of the left valve body, the surface of the left half section of the valve cavity 12 is smooth, and an internal thread structure is formed on the right half section of the valve cavity 12.
The right side of right valve body 2 is formed with outlet channel 21, and the left side is formed with valve rod mount pad 22, be formed with the medium passageway 23 that switches on with outlet channel 21 on the valve rod mount pad 22, 2 lateral walls of right valve body are formed with the external screw thread structure, right valve body 2 and left valve body 1 link into an organic whole through the screw thread, simple structure, the equipment is convenient.
And a sealing gasket 6 is arranged between the left valve body 1 and the right valve body 2, so that the sealing fit between the left valve body 1 and the right valve body 2 is further ensured.
The valve clack 3 is matched with the valve cavity 12, the valve clack 3 is arranged in the valve cavity 12 and is in clearance sliding fit with the valve cavity 12, a sealing surface 31 capable of being in sealing fit with the left valve body 1 is formed on the left side of the valve clack 3, and a flow guide hole 32 is formed on the outer side of the valve clack 3 opposite to the sealing surface 31.
Valve rod 4 one end is connected with valve clack 3, and the other end runs through valve rod mount pad 22, with the cooperation of sliding of valve rod mount pad 22, wherein through welding structure as an organic whole between valve rod 4 and the valve clack 3.
The spring 5 is made of corrosion-resistant materials and sleeved outside the valve rod 4, two ends of the spring 5 are respectively abutted against the valve clack 3 and the valve rod mounting seat 22, and the valve clack 3 and the left valve body 1 can be driven to keep sealed.
When the medium flows forwards, the medium pushes the valve clack 3 to move rightwards through the inlet channel 11, the valve clack 3 moves rightwards to drive the spring 5 to extrude rightwards, the medium can continuously flow out of the outlet channel 21 after passing through the flow guide hole, the valve cavity and the medium channel, when the kinetic energy of the medium is larger, the elastic potential energy converted into the spring 5 is larger, the distance of the valve clack 3 moving rightwards is larger, and the passing media are more; when no medium flows into the inlet channel 11 to provide pressure, the spring 5 is restored in the elastic deformation to push the valve clack 3 to move leftwards, so that the valve clack 3 is sealed with the left valve body 1, and the medium cannot flow reversely.
By adopting the scheme, the device has the advantages of simple and compact structure, convenience in processing and assembling, low production cost, small resistance, no blocking when being opened and closed and stable operation balance.
