Drawings
Fig. 1 is an overall schematic view of the present invention.
In the figure: 1. the valve comprises a valve body, 2, a water inlet, 3, a water outlet, 4, a ring groove, 5, a valve cover, 6, a valve rod, 7, a spring, 8, a sealing element, 9, a rotating element, 10, a rubber layer, 11, a compression nut, 12, a packing gland, 13, packing, 14, a hand wheel, 15, a nut, 16 and a valve clack.
Detailed Description
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.
Referring to fig. 1, the present invention provides a technical solution: iron white copper check valve without leakage in a zero-return meter seal, which comprises a valve body 1, both ends all are equipped with water inlet 2 and delivery port 3 about valve body 1, the inside profile of valve body 1 is shown in fig. 1, the height that highly is less than delivery port 3 of water inlet 2, the top of valve body 1 is equipped with annular 4, be equipped with the screw thread in the annular 4, threaded connection has valve gap 5 in the annular 4, the inside wall spiro union of valve gap 5 has valve rod 6, the top of valve gap 5 is equipped with sealing member 8, the bottom fixed mounting of valve gap 5 has spring 7, the spring 7 shown in fig. 1 is in the compression state, elasticity through spring 7, make the bottom of valve clack 16 block up in the intersection of water inlet 2 and delivery port 3, the bottom fixed mounting of spring 7 has valve clack 16, the bottom laminating of valve rod 6 is at the top of valve.
The check sealing pressure specified in the GB/T596 original structure valve standard is 0.3MPa, namely when the valve is arranged on a shipboard and the valve outlet is at 0-3 m depth of water under water, the check function is invalid due to the small pressure of seawater, the seawater flows back into a pipeline, the fore-line equipment is soaked by the seawater, the equipment is damaged, even the function is invalid, and therefore the problem that the check function of the valve is required to be reliable in sealing between zero pressure and nominal pressure of water and can resist corrosion of high-salinity seawater is solved. The parts of the GB/T596 stop check valve, such as the valve body 1, the valve rod 6, the valve cover 5, the gland nut 11 and the like which are in direct contact with the medium, are replaced by iron white copper (BFe30-1-1) materials which are more resistant to seawater corrosion, so that the corrosion resistance of the valve is greatly enhanced
Specifically, the rubber layer 10 is fixedly mounted at the bottom end of the valve flap 16, and the rubber layer 10 is used for increasing the sealing performance between the bottom of the valve flap 16 and the interior of the valve body 1 and avoiding water leakage.
Specifically, the sealing member 8 includes a compression nut 11, the compression nut 11 is screwed on the top of the outer side wall of the bonnet 5, a packing gland 12 and a packing 13 are arranged between the compression nut 11 and the bonnet 5, and the packing 13 is used for ensuring the sealing of the valve rod 6 and the bonnet 5.
Specifically, the rotating member 9 includes a hand wheel 14 and a nut 15, and a middle portion of the hand wheel 14 and a top end of the valve stem 6 are connected by the nut 15.
The working principle is as follows: when the valve is in a closed state, the bottom end of the valve rod 6 is abutted against the valve clack 16, so that the sealing surface of the valve clack 16 is contacted with the internal sealing surface of the valve body 1 to be used as a stop valve.
Anticlockwise rotation hand wheel 14, drive valve rod 6 and rise perpendicularly, the valve is in the open mode, owing to install spring 7 between valve gap 5 and valve clack 16, so valve clack 16 is in the closed mode all the time, when the medium flows in from left side water inlet 2, owing to receive the effect of medium power messenger valve clack 16 and rise, the valve is opened this moment, the medium flows out through right side delivery port 3, when the medium flows in the valve body from right side delivery port 3 against the current, because spring 7's effect valve is in the closed mode all the time, can not cause the medium to flow against the current, use as the check valve this moment.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
