Abstract

The utility model discloses a nitrogen compressor pneumatic valve end cover, including end cover (1), the through -hole is offered to the outer terminal surface of end cover (1) axial, sets up butt clamp bolt (2) and butt clamp nut (3) in the through -hole, and butt clamp bolt (2) and butt clamp nut (3) set up gasket in butt clamp bolt (2), butt clamp nut (3) with the one side of end cover (1) contact with the whole covers of through -hole. The beneficial effects are that: opening the hole on the end cover and replacing the internal thread hole, guarantee that the screw rod does not rotate when the installation by a wide margin, can avoid the damage of end cover like this, rubber gasket can also guarantee sealing performance with the whole covers of through -hole when avoiding the end cover to damage.

Description

Nitrogen compressor air valve end cap

Technical field

This utility model is related to a kind of end cap, and in particular to a kind of nitrogen compressor air valve end cap.

Background technology

Nitrogen compressor air valve end cap material is cast iron, and end cover designs are connected as studding, need to press very tight during joint, otherwise Gas leakage.Because internal thread is on cylinder cap, cylinder cap material is casting pig, and low intensity, Jing the situation for sliding tooth often occurs, is directed at whole cylinder cap Can not use.Impact equipment reliability of operation.

The content of the invention

For the problem that above-mentioned prior art is present, this utility model provides a kind of nitrogen compressor air valve end cap, and end cap is difficult Damage, increase end cap service life.

To achieve these goals, the technical solution adopted in the utility model is：A kind of nitrogen compressor air valve end cap, including end Lid, end cap axial outer end face opens up through hole, arranges in through hole to folder bolt and to pressing from both sides nut, will lead to pressing from both sides bolt and to pressing from both sides nut Hole all covers, and in the one side contacted with end cap to pressing from both sides bolt, to pressing from both sides nut pad is arranged.

Further, described pad is rubber sheet gasket.

Beneficial effect is：Opened hole replaces internal thread hole on end cap, it is ensured that when mounted screw rod is not significantly rotated, and so can be kept away Exempt from the damage of end cap, rubber sheet gasket all covers through hole, it is to avoid end cap can also ensure that sealing property while damage.

Description of the drawings

Fig. 1 is structural representation of the present utility model；

In figure：1st, end cap, 2, to press from both sides bolt, 3, to press from both sides nut.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail.

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

As shown in figure 1, this utility model includes end cap 1, the axial outer end face of end cap 1 opens up through hole, arranges in through hole to folder Bolt 2 and to pressing from both sides nut 3, all covers through hole to pressing from both sides bolt 2 and to pressing from both sides nut 3, to pressing from both sides bolt 2, to pressing from both sides nut 3 with end The one side of the contact of lid 1 arranges pad, and pad is rubber sheet gasket.Opened hole replaces internal thread hole on end cap 1, it is ensured that screw rod when mounted Significantly do not rotate, can so avoid the damage of end cap 1, rubber sheet gasket from all covering through hole, it is to avoid while end cap 1 is damaged also Ensure that sealing property.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new The scope of type is by claims rather than described above is limited, it is intended that the equivalency fallen in claim is contained All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as restriction Involved claim.

The above, preferred embodiment only of the present utility model is every according to this not to limit this utility model Any trickle amendment, equivalent and improvement that the technical spirit of utility model is made to above example, should be included in this Within the protection domain of utility model technical scheme.
