Abstract
The utility model discloses a high nickel alloy ball valve end cover, including the end cover that is used for connecting the valve body, its characterized in that: flange part in the middle part of tip flange subtotal is served to the outward appearance of end cover, tip flange part go up to open and have the notes fat hole that is linked together with the end cover inner chamber, should annotate to install on the fat hole and annotate the fat valve, and install to arrange in and annotate the downthehole check valve of fat annotating fat valve lower extreme department. The utility model discloses a high nickel alloy ball valve end cover who obtains, it is reasonable, corrosion -resistant and high -pressure to have a structural design, has guaranteed the performance and the processing performance of product.
Description
Technical field
The utility model relates to Langaloy product technical field, is specifically related to a kind of nickel alloy ball valve end cap.
Background technique
Ball valve is widely used in the industries such as chemical industry, oil, metallurgy, electric power as a kind of piping element.Ball valve is generally made up of component such as valve body, end cap, spheroid, valve seats.
Current high-pressure anticorrosion ball valve generally all adopts forged steel three pieces type structural design, particularly for small-aperture ball valve particularly below DN100, if be applied to seawater corrosion operating mode, much all adopt two phase stainless steel or Langaloy manufacture, but the structure length specified due to standard is short especially, due to limited space, and 3 stops ball valve all can not design grease pouring valve as Large diameter ball valve on end cap.
Model utility content
The purpose of this utility model provides a kind of reasonable in design to solve above-mentioned the deficiencies in the prior art, improve a kind of nickel alloy ball valve end cap of existing small-aperture ball valve sealability.
To achieve these goals, a kind of nickel alloy ball valve end cap designed by the utility model, comprise the end cap for connecting valve body, it is characterized in that: the appearance end of described end cap comprises end flange part and central flange part, described end flange part has the greasing hole with end cap intracavity inter-connection, this greasing hole is provided with grease pouring valve, and at grease pouring valve lower end, the one-way valve be placed in greasing hole is installed.
Preferably, described end cap is nickel alloy end cap or two phase stainless steel end cap.
Preferably, described greasing hole comprises radial greasing hole and axial greasing hole.
A kind of nickel alloy ball valve end cap that the utility model obtains, valve gap is installed its reasonable in design of grease pouring valve, adopts nickel alloy end cap or two phase stainless steel end cap can reach corrosion-resistant and high pressure, ensure that usability and the technology capability of product.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: end cap 1, end flange part 2, radial greasing hole 3, grease pouring valve 4, one-way valve 5, axial greasing hole 6.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, a kind of nickel alloy ball valve end cap that the utility model provides, comprise the end cap 1 for connecting valve body, the appearance end of described end cap 1 comprises end flange part 2 and central flange part 7, described end flange part 2 has the greasing hole with end cap intracavity inter-connection, this greasing hole is provided with grease pouring valve 4, and at grease pouring valve 4 lower end, the one-way valve 5 be placed in greasing hole is installed.
Further, described end cap 1 is nickel alloy end cap or two phase stainless steel end cap.
Further, described greasing hole comprises radial greasing hole 3 and axial greasing hole 6.Be designed with radial greasing hole and axial greasing hole, good manufacturability, this patten's design also has the arrangement of processing technology as shown in the figure, good manufacturability.
A kind of nickel alloy ball valve end cap obtained for this design is described further, 1, grease pouring valve is positioned in the end flange part of Cover members, reasonably utilize the space of valve itself, make the problem of saving cost and solving smaller diameter valve insufficient space.2, valve gap adopts nickel alloy or two-phase stainless steel making, seawater corrosion resistance, and reliability is high, can work under these circumstances for a long time, increases working life, greatly reduces labour cost.
For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by the utility model are determined.
