Abstract

The utility model provides an anti-leakage straightway valve; an inner valve with an inlet is screwed with an outer valve with an outlet; a conical cavity which is arranged in the outer valve is provided with a closed rotary conical valve core, and the inner side is provided with a top spring; the upper part of the conical valve core which penetrates through the outer valve is provided with a rotating handle and a locking cap; an inner cavity channel of a conical valve is communicated with the inlet when rotating to be corresponding to the outlet; by adopting a built-in conical valve core which rotates and corresponds in the inner conical cavity of the outer valve, the anti-leakage straightway valve is characterized by good sealing effect and abrasion prevention; because of the top spring arranged below, the conical valve core and the valve are more closed by being tightened, so as to achieve the effect of no leakage; and the anti-leakage straightway valve can be widely applied to all tap water and machine tool supplied cooling water, and serve as a valve of all water pipes, oil pipes and gas pipes.

Description

The leakproof throughway valve

Technical field

The utility model relates to the switch valve that a kind of running water pipe, oil pipe or tracheae use, a kind of specifically leakproof throughway valve.

Background technique

The various valve switchs of installing and using now, in use for some time, all occur the inner core wearing and tearing easily and produce leakage phenomenon, mainly former is because inner core is after multiple switching rotates, cause and produce the space between wearing and tearing and the valve body and leak, can only change valve body and solve, and frequent transposing valve switch was both time-consuming, had caused the waste of resource again.

Summary of the invention

The purpose of this utility model is to provide a kind of throughway valve of good leak-proof effect, can not produce leakage phenomenon owing to inner core does not wear and tear in long-term using process.

The utility model comprises import, outlet, top spring and locking cap, the technological scheme that adopts is: the inner valve body that is provided with import adopts the screwed union mode outer valve of taking out of mouthful that spins, pack in the tapered cavity that is provided with in the outer valve rotatable tapered spool of a driving fit, the bore passages of this tapered spool setting is turning to and is exporting the bore passages that seasonable formation and import are connected.

A top spring also is equipped with in the below that also is included in tapered spool in the such scheme, and the top power packing by spring makes tapered spool and the built-in more driving fit of tapered cavity of outer valve, simultaneously, can guarantee in use the more driving fit sealing along with the break-in effect.

A handle with sleeve is installed in the described tapered spool outside after passing outer valve, and locking cap of spinning.It is directed fixing to be that the top of handle with sleeve and tapered spool adopts inside and outside hexagonal to be nested, and the top screws with hold-doun nut and get final product, during use, pulls handle with sleeve and can drive the Push And Release that tapered inner core rotates the realization throughway valve.

For the needs of suitable various uses, the described inner valve body of bringing mouth into, its import can be laterally vertical, also can be the upwards import of bending.

The utility model is established tapered cavity in above-mentioned tapered spool and the outer valve and is carried out driving fit by adopting, and the technological scheme of top spring is set in tapered valve in-core side, make the phenomenon that can not produce wear and leakage between spool and the valve body, and can reach and desire break-in, airtight good more effect, solved switch valve in the prior art easily wearing and tearing cause the problem revealed, can be widely used in various running water pipes, oil pipe and tracheae and use as valve switch.

Embodiment

Shown in accompanying

drawing

1,2,3 embodiments: the inner valve body 2 that is provided with import 4 adopts the screwed union modes to spin and one takes mouthfuls 5 outer valve 1 out of, the rotatable tapered spool 3 of one driving fit is housed in the tapered cavity 6 that is provided with in outer valve 1, and the bore passages 7 that this tapered spool 3 is provided with is turning to and is exporting the bore passages 7 that 5 pairs of seasonable formations and import 4 connect.The top spring 8 that is used for the packing driving fit is housed in the inboard of tapered spool 3.Handle with sleeve 9 is equipped with in tapered spool 3 outsides after passing outer valve 1, and is rotary with a locking cap 10.The inner valve body 2 of bringing mouth 4 into is laterally vertical import 4 or the upwards import 4 of bending.

During enforcement, it is good that the utility model can adopt copper material or stainless steel material to be processed as, described import 4 and outlet 5 can be designed to outer silk head or internal thread head, also outlet can be produced is that the tube head that directly uses all can, and between outer valve 1 and the inner valve body 2 that spins, add washer sealing, simultaneously between handle with sleeve 9 and outer valve 1, add metal washer, favourable handle with sleeve 9 rotations.
