Abstract
The invention relates to a forged steel through shut-off valve which comprises a valve body, a valve rod and a valve cover. An inlet and an outlet are formed in the valve body. The valve cover is connected with the valve body. The valve rod is arranged in the valve cover and a hand wheel is arranged at the upper end of the valve rod. A valve chamber is arranged in the valve body and respectively communicated with the inlet and the outlet. A valve piston is arranged at the lower end of the valve rod and extends into the valve chamber to be connected with the inlet or the outlet of the valve chamber in a sealed mode. The valve rod and the valve cover are movably connected through threads. The valve rod moves up and down relative to the valve cover. A center hole is formed in the upper end of the valve cover. A bush is arranged in the center hole and a pressing nut is arranged on the bush. An externally-sleeved nut is arranged at the outlet of the valve body. A nipple connector is arranged in the externally-sleeved nut. According to the forged steel through shut-off valve, the valve body and the valve cover are machined with forged steel and the bush is arranged in the center hole of the valve cover. The valve piston is matched with the center hole of the valve chamber to form good sealed connection. The forged steel through shut-off valve is high in strength, good in sealing performance, compact in structure, long in service life and convenient to operate and use.
Description
Technical field
The present invention relates to valve, especially a kind of intensity is higher, the forged steel through shut off valve of good seal.
Background technique
At present, existing stop valve is generally common cock-type or flat stifled formula structure, and material is mainly cast iron, and existing stop valve exists valve mechanism complicated conventionally, and intensity is not high, not wear-resistant, easy to leak, the shortcoming such as working life is short.Existing cast steel stop valve is because working ability is limit, and its structure is comparatively simple, sealing is affected, and the replacing of the easily damaged parts of stop valve is convenient not.
Summary of the invention
The object of this invention is to provide that a kind of intensity is higher, good seal, and working life longer forged steel through shut off valve.
The object of the invention is by realizing by the following technical solutions:
Forged steel through shut off valve, comprise valve body, valve rod and valve gap, valve body is provided with import and outlet, and valve gap is connected with valve body, and valve rod is located in valve gap, valve rod upper end is provided with handwheel, described valve inner is provided with valve chamber, and valve chamber is connected with described import and outlet respectively, and described valve rod lower end is provided with valve plug, valve plug extend in the valve chamber of valve body, and can with valve chamber in import or export form and to be tightly connected; Between described valve rod and valve gap, by thread-shaped, become to be flexibly connected, valve rod relatively valve gap moves up and down; Described valve gap upper end is provided with center hole, in this center hole, is provided with lining, and lining is provided with gland nut.
As the preferred technical solution of the present invention, described valve body import and valve outlet coaxial line.
As the preferred technical solution of the present invention, the import or export place of described valve body is also provided with cap nut, is provided with newborn shape joint in cap nut.
As the preferred technical solution of the present invention, the outlet of described valve body is made as taper shape, and described newborn shape joint and valve outlet are mutually adaptive.
As the preferred technical solution of the present invention, the import of described valve body and the junction surface of valve chamber are made as conical surface, and this conical surface is located at the central position of valve chamber suitable with the top of described valve plug.
As the preferred technical solution of the present invention, described valve body or valve gap are processed into by forged steel.
The invention has the beneficial effects as follows: with respect to prior art, valve body of the present invention and valve gap are processed by forged steel, and intensity is higher; In the center hole of valve gap, be provided with lining, the center hole adaptation of valve plug and valve chamber also forms good being tightly connected.Intensity of the present invention is high, good seal, compact structure, and long service life, easy for operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is sectional structure schematic diagram of the present invention.
