The utility model has the advantages that: the valve has a simple structure, innovatively designs a multifunctional valve with three functions of stopping, adjusting and non-return, can reduce the types and the number of valves installed by process pipelines, saves the process cost of the pipelines, and achieves the multifunctional valve with good sealing performance, accurate flow adjustment and rapid non-return, and one valve can replace three valves for use.

Drawings

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

Fig. 1 is a front sectional view of an embodiment of the present invention.

In fig. 1, a handle 1, a valve rod nut 2, a valve cover 3, a valve rod 4, a spring 5, a bushing 6, a check column 7, a gland nut 8, a guide sleeve 9, a valve seat 10, a valve body 11, a water inlet A, a water outlet B, an upper valve cavity C, a flow hole D, a vertical hole E and a horizontal hole F.

Detailed Description

In fig. 1, a stop adjusting check valve comprises handle (1), valve-stem nut (2), valve gap (3), valve rod (4), spring (5), bush (6), check post (7), gland nut (8), uide bushing (9), disk seat (10), valve body (11), disk seat (10) are equipped with to valve body (11) lower extreme, bush (6) are equipped with to disk seat (10) upper end, valve gap (3) are equipped with to bush (6) upper end, check post (7) are equipped with to the upper end of the inside disk seat (10) of bush (6), spring (5) are equipped with to check post (7) upper end. The valve body (11) is provided with a water inlet (A) and a water outlet (B), the upper end of the check column (7) is provided with an upper valve cavity (C), the lower end of the lining (6) is provided with a circulation hole (D), the check column (7) is provided with a vertical hole (E) and a horizontal hole (F), and the water outlet (B) is communicated with the circulation hole (D), the horizontal hole (F), the vertical hole (E) and the upper valve cavity (C).

The guide sleeve (9) is arranged at the upper part of the non-return column (7), the compression nut (8) compresses and fixes the guide sleeve (9), and the non-return column (7) is not fixedly connected with the valve rod (4). The valve cover (3), the lining (6), the non-return column (7) and the valve rod (4) form an upper valve cavity (C).

The utility model discloses a theory of operation is: handle (1) is rotated anticlockwise, valve rod nut (2) anticlockwise rotates valve rod (4) rebound, the medium pressure of water inlet (A) is used in the lower extreme of check post (7), check post (7) rebound compression spring (5), check post (7) break away from disk seat (10), the medium arrives the valve pocket by water inlet (A) through the clearance of check post (7) and disk seat (10) through circulation hole (D) on bush (6) from delivery port (B) output valve body (11), the valve is opened. The flow rate is adjusted by adjusting the opening of the check column (7) by the handle (1). The upper part of the non-metal guide sleeve (9) is arranged on the non-return column (7), and the non-metal guide sleeve can slide up and down in the bushing (6) to play a role in guiding the non-return column (7) so as to prevent the non-return column (7) from being in contact with the metal surface of the bushing (6) to cause strain.

When the water inlet (A) stops feeding water, the check column (7) is pushed to move downwards under the elastic force of the spring (5), the check column (7) compresses the valve seat (10), a medium reaches the upper valve cavity (C) at the upper end of the check column (7) through the water outlet (B), the circulation hole (D), the horizontal hole (F) and the vertical through hole (E), the check column (7) further compresses the valve seat (10) under the medium pressure, and the valve realizes check sealing.

The handle (1) is rotated clockwise, the valve rod nut (2) rotates clockwise, the valve rod (4) moves downwards and pushes the check column (7) to move downwards, the check column (7) is tightly pressed on the valve seat (10), the check column (7) and the sealing pair of the valve seat (10) cut off the circulation of media, and the valve is closed.
