Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows: as shown in fig. 1, the utility model provides a technical solution: comprises a valve body 1, a hand wheel 14, a valve rod 7 and a valve cover 9; the valve body 1 is in an inverted T shape, the longitudinal valve body is communicated with the transverse valve body and is integrally formed, the transverse valve body is composed of an outlet end valve body 1-2 and an inlet end valve body 1-1, a water through hole 17 is formed between the outlet end valve body 1-2 and the inlet end valve body 1-1, a valve cover 9 is arranged at the top end of the longitudinal valve body, the valve cover 9 is also in an inverted T shape, a threaded through hole for a valve rod 7 to penetrate through is formed in the center of the longitudinal portion of the valve cover 9, external threads are formed outside the valve rod 7, the valve rod 7 is in threaded connection with the valve cover 9 and penetrates through the valve cover 9, a second clamping nut 13 is arranged at the top end of the longitudinal portion of the valve cover 9, a; still include valve clack 5, valve clack 5 upper surface central point puts and is equipped with external screw thread step 52, external screw thread step upper surface central point puts and is equipped with guide arm 51, valve clack 5 lower surface central point puts and is equipped with external screw thread post 53, be equipped with first nut 2 on the external screw thread post 53, the inside of valve rod 7 lower part is seted up porosely, the guide arm 51 of valve clack 5 inserts in the downthehole of valve rod 7 lower part, the outer circumference cover of valve rod 7 has spring 18, spring 18 upper end supports valve gap 9, the valve clack 5 is supported to the spring 18 lower extreme, valve clack 5 lower surface sets gradually sealed 4 from top to bottom, fixed separation blade 3, sealed 4, the hole that supplies external screw thread post 53 to pass is seted up at.

Move valve rod 7 to the topmost through rotatory hand wheel 14, because spring 18's elastic force effect, valve clack 5 is downward all the time and the marginal laminating of crossing water hole 17, when water pressure is greater than spring 18's elasticity, rivers will push up valve clack 5 and flow through water hole 17, when water pressure is less than spring 18's pressure, valve clack 5 can closely laminate with the edge of crossing water hole 17, and rivers are unable to pass through, and the rivers that flow through water hole 17 simultaneously also can't flow back, this moment the utility model discloses a one way check valve drives valve rod 7 through rotatory hand wheel 14 and moves to the lower extreme downwards, and valve rod 7 tightly presses valve clack 5 on the edge of crossing water hole 17 this moment, the utility model discloses a stop valve.

Example two: as shown in fig. 2, add first jam nut 6, the bottom edge of valve rod 7 is equipped with the turn-ups, and valve rod 7 lower part cover has first jam nut 6, and the turn-ups upper surface contacts with the inside upper surface of first jam nut 6, and first jam nut 6 inside wall is the internal thread, and the external screw thread step 52 and the first jam nut 6 threaded connection of valve clack 5.

During the use, drive valve rod 7 through rotatory hand wheel 14 and reciprocate to make valve clack 5 reciprocate, when needing to turn off the valve, rotatory hand wheel 14 drives valve rod 7 and valve clack 5 downstream to valve clack 5 with cross the inseparable laminating in water hole 17 edge, valve clack 5 will cross that water hole 17 is stifled deadly this moment, water can't flow through water hole 17, the valve is in the closed condition, when needing to open the valve, reverse rotation hand wheel 14 drives valve rod 7 and valve clack 5 and upwards moves, valve clack 5 leaves the water hole can, this moment, the utility model discloses an adjustable stop valve.

The utility model discloses seal part is valve clack 5, in order to further improve sealed effect, set gradually sealed 4, fixed separation blade 3 on valve clack 5 lower surface from top to bottom, because reasons such as life, sealed effect can appear descending and cause the valve can not close completely, has the leakage condition, at this moment, can open valve gap 9, take out valve rod 7 from valve body 1, then change valve clack 5 alone, sealed 4 or fixed separation blade 3 of filling up, need not to change whole valve, reduce cost of maintenance.

Considering that the valve body needs to be made into an adjusting valve body for use in the sewage discharge or later, the reserved sewage discharge outlet 16 is arranged on the bottom surface of the valve body 1, and when the valve body needs to be made into the adjusting valve body for use in the sewage discharge or later, the reserved sewage discharge outlet 16 is processed; for the convenience of the connection between the utility model and the water pipeline, the outlet valve body 1-2 and the inlet valve body 1-1 can be directly butt-welded with the pipeline, and can also be welded with a clamping pressure joint, a ring pressure joint, an external thread joint, a movable joint, a socket joint welding joint, a copper pipe transition joint, a flange and the like.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
