In view of the above shortcomings of the prior art, an object of the present invention is to provide a detachable Y-shaped stop valve for solving the problem of high maintenance cost due to the difficult replacement after the valve body is eroded in the prior art.

In order to solve the technical problem, the utility model discloses a realize according to following mode: a detachable Y-shaped stop valve comprises a valve core, a valve rod and a hand wheel mechanism; one end of the valve rod is connected with the hand wheel mechanism, the other end of the valve rod is connected with the valve core, and the valve rod comprises a valve cover and a valve body, wherein the valve cover is detachably connected with the valve body; a sleeve and a valve seat are arranged in the valve body, one end of the sleeve touches the valve cover, the other end of the sleeve touches the valve seat, and the valve seat is tightly pressed in the valve body through the sleeve; and a through hole is formed in the side wall of the sleeve corresponding to the water outlet of the valve body.

Furthermore, the valve body is connected with an external thread column, and the valve cover is provided with a corresponding through hole; the external thread post passes the through-hole, the valve gap pass through the nut with the cooperation of external thread post can be dismantled and be connected on the valve body.

Furthermore, a sealing ring is arranged on the valve seat, and sealing is formed between the valve seat and the sleeve through the sealing ring.

Further, when the stop valve is closed, the valve core and the sealing ring are in compression fit to form sealing.

Further, the valve rod passes through the valve cover and is arranged in the sleeve in an adjustable lifting mode.

As mentioned above, the utility model discloses a detachable Y shape stop valve through ingenious design for the valve gap can conveniently be pulled down from the valve body, can directly change by the erosion disk seat and case, thereby has reduced cost of maintenance and time.

Reference is made to the following in corresponding reference numbers in the drawings of the specification:

the valve comprises a valve cover 1, a valve body 2, an external thread column 21, a sleeve 3, a valve seat 4, a nut 5, a valve core 6, a valve rod 7 and a hand wheel mechanism 8.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present application are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, change of the ratio relationship or adjustment of the sizes should still fall within the scope of the present invention without affecting the functions and the achievable purposes of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

As shown in FIG. 2, the utility model provides a detachable Y-shaped stop valve, including valve gap 1 and valve body 2, valve gap 1 can dismantle to be connected in valve body 2. Be equipped with sleeve 3 and disk seat 4 in the valve body 2, the one end of sleeve 3 touches valve gap 1, and the other end touches disk seat 4, and disk seat 4 is compressed tightly in the valve body through sleeve 3. The lateral wall of the sleeve 3 is provided with a through hole corresponding to the water outlet of the valve body 2, so that the water flow can circulate conveniently. The valve rod 7 penetrates through the valve cover 1 and is arranged in the sleeve 3 of the valve body 2 in an adjustable lifting mode, one end of the valve rod is connected with the hand wheel mechanism 8, and the other end of the valve rod is connected with the valve core 6.

The valve body 2 is connected with an external thread column 21, and the valve cover 1 is provided with a corresponding through hole. The external thread column 21 passes through the through hole, and the valve cover 1 is detachably connected to the valve body 2 through the matching of the nut 5 and the external thread column 21. And a sealing ring is arranged on the valve seat 4, and sealing is formed between the valve seat 4 and the sleeve 3 through the sealing ring. When the stop valve is closed, the valve core 6 and the sealing ring are in compression fit to form sealing.

When the water-saving valve is used, the hand wheel mechanism 8 drives the valve core 6 on the valve rod 7 to descend and press the valve seat 4 in the valve body 2 to seal and block water flow. When the Y-shaped stop valve is eroded for a long time and needs maintenance, the nut 5 is unscrewed, the valve cover 1 is detached from the valve body 2, the sleeve 3, the valve core 6 and the valve seat 4 in the valve body 2 are taken out, and the valve seat 4 and the valve core 6 are replaced so that the Y-shaped stop valve can be continuously used.

To sum up, the utility model discloses a detachable Y shape stop valve through ingenious design for the valve gap can conveniently be pulled down from the valve body, can directly change by the erosion disk seat and case, thereby has reduced cost of maintenance and time. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
