Abstract

The utility model discloses a valve core with a small overflow chamber. The valve core is composed of an ejector rod (1), a nut (2) and a valve core body (3), the ejector rod (1) comprises a rod body (4) and a protrusion cap (5) which is arranged at the end of the rod body (4), an ejector rod hole (6) and a valve core hole (7) are sequentially arranged on the nut (2) along an axial direction, a protrusion cap hole (8) is arranged at the rear end of the valve core hole (3), the protrusion cap (5) of the ejector rod (1) is arranged in the protrusion cap hole (8) of the valve core body (3), the rod body (4) of the ejector rod (1) penetrates through the ejector rod hole (6) of the nut (2), and the valve core body (3) is arranged in the valve core hole (7) of the nut (2). The small overflow gun valve core has the advantages that by means of a split structure, the structure of each independent portion is simple and convenient to process so that the processing efficiency is improved, and the processing cost is reduced; and the valve core with the small overflow chamber is provided with a function of automatically adjusting the core so that the processing yield is improved and maintenance costs are reduced.

Description

Little overflow rifle spool

Technical field

The utility model relates to the spool technical field, particularly little overflow rifle spool.

Background technique

Existing little overflow rifle spool all is structure as a whole; Be that little overflow rifle spool is to be processed by a part integral body, but little overflow rifle spool outer shape is complicated, is not easy to processing; Yielding after heat treatment; The shank of spool and the coaxality of surfacing are difficult to assurance, thereby cause little overflow rifle spool work efficiency low, and rate of good product is low, cost is high; And after the local damage of little overflow rifle spool, have to change whole spool, maintenance cost is high.

The model utility content

The purpose of the utility model is to overcome the shortcoming of existing technology, and the little overflow rifle spool that a kind of work efficiency is high, yield rate is high is provided.

The purpose of the utility model realizes through following technological scheme:

Little overflow rifle spool; It is made up of push rod, nut and spool, and described push rod comprises shaft and the protruding cap that is arranged at the shaft end, and said nut is disposed with jogger hole and spool bore along its axial direction; The rear end of described spool is provided with protruding cap hole; The protruding cap of said push rod is arranged in the protruding cap hole of spool, and the shaft of push rod runs through the jogger hole of nut, and described spool is arranged in the spool bore of nut.

Be fixed as one through being threaded between described spool and the nut.

The protruding cap of described push rod between protruding cap hole and jogger hole axially, radially all can float.

Also be provided with the adjustment chamber on the described nut, said adjustment chamber is between jogger hole and spool bore

The somewhat larger in diameter of described jogger hole is in the diameter of push rod.

The utlity model has following advantage:

The utility model adopts split-type structural; Baroque little overflow rifle spool is decomposed into push rod, nut and spool three parts; Simple in structure being easy to of each unitary part processed; Thereby solved little overflow rifle spool and adopted the big problem of integrative-structure difficulty of processing, improved work efficiency, reduced processing cost; Be provided with certain interval between the jogger hole of little overflow rifle spool assembling back push rod and nut; It can make little overflow rifle spool have the function of self-aligning; After little overflow rifle spool assembling is accomplished,, also can adjust automatically even the coaxality of push rod and spool is not high; Improve the rate of good product of processing, reduced cost equally; And after little certain damage parts of overflow rifle spool, only need to change the part that damages and get final product, reduced maintenance cost.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further description:

As shown in Figure 1, little overflow rifle spool, it is made up of push rod 1, nut 2 and spool 3; As shown in Figure 2, described push rod 1 comprises shaft 4 and the protruding cap 5 that is arranged at shaft 4 ends, and is as shown in Figure 3; Said nut 2 is disposed with jogger hole 6 and spool bore 7 along its axial direction; As shown in Figure 4, the rear end of described spool 3 is provided with protruding cap hole 8, and the protruding cap 5 of said push rod 1 is arranged in the protruding cap hole 8 of spool 3; The shaft 4 of push rod 1 runs through the jogger hole 6 of nut 2, and described spool 3 is arranged in the spool bore 7 of nut 2.

All be fixed as one between described spool 3 and the nut 2 through being threaded.

The protruding cap 5 of described push rod 1 between protruding cap hole 8 and jogger hole 6 axially, radially all can float.

Also be provided with the adjustment chamber on the described nut 2, said adjustment chamber is between jogger hole 6 and spool bore 7; The somewhat larger in diameter of described jogger hole 6 is in the diameter of push rod 1; Be provided with certain interval between the jogger hole 6 of little overflow rifle spool assembling back push rod 1 and nut 2; After little overflow rifle spool assembling is accomplished; Even push rod 1 is not high with the coaxality of spool 3, also can adjust automatically, make little overflow rifle spool have the function of self-aligning.

Claims
