The purpose of this utility model can be realized by following technical proposal:A kind of water discharge valve, including upper shell with And the lower housing being fixedly connected with upper shell, it is connected to form valve chamber inside the upper shell and lower housing, and the lower housing It is provided with the valve opening being connected with valve chamber, which is characterized in that check valve assembly, the check-valves are provided in the valve chamber Component includes plug, non-return bottom plug and fits with valve chamber inner wall, and tubular sleeve moving up and down, the tubular casing There is fluid channel in cylinder, the plug and non-return bottom plug are respectively arranged at the lower section and top of tubular sleeve, and the two it Between be connected with valve rod through fluid channel, the bottom end of the upper shell is provided with circumferential inwardly protruded limit chuck, upper casing Body top is provided with the through-hole for extending radially through upper shell, and the blend stop for braking non-return bottom plug, institute are inserted in the through-hole Stating has limited step in the inner end wall of lower housing, the limit chuck is used to limit the activity of tubular sleeve with limited step The bore of range, the upper/lower terminal face fluid channel of the tubular sleeve is respectively smaller than the radius of non-return bottom plug and plug, described Several osculums being connected with valve chamber are both provided on the both sides end wall of lower housing.
The operation principle of the utility model discharging valve:When have in valve body fluid by when, hydraulic pressure can impact plug, and plug is in pressure Impact under move up, make thereon end face be resisted against on the lower face of tubular sleeve, then push tubular sleeve move upwards, When non-return bottom plug can not be continued up because being limited by blend stop, flow will continue to push tubular sleeve to limiting chuck Place, at this time tubular sleeve outer end face sealing cover osculum, be formed between tubular sleeve and non-return bottom plug for fluid into Entering the gap of fluid channel, fluid can normally be discharged, when equipment is stopped, due to there is no hydraulic pressure to give upward thrust, Check valve assembly is quickly fallen after rise under gravity, and tubular sleeve, which moves downward, to be resisted against on limited step, at this time osculum It being open, non-return bottom plug is resisted against tubular sleeve Double End limitation liquid reflux fluid channel under the impact of residual liquid, Then it is flowed out from osculum, completes drainage works.
In a kind of above-mentioned water discharge valve, the plug includes cylindrical ontology and flow guiding head, described The radius of a circle size of ontology is identical as valve opening radius of a circle, and the flow guiding head is in cone, and its vertex of a cone passes through circular arc mistake It crosses.Conical flow guiding head plays the role of shunting, so that it is entered from two side clearances fluid even partition, the radius of a circle of ontology Size is consistent with valve opening circumferential size, plug can be helped in downward fall after rise, certain sealing is played in the cooperation with valve opening Property.
In a kind of above-mentioned water discharge valve, the end that the valve rod is connected with plug extends to inside plug, The end being connected with non-return bottom plug axially penetrates through non-return bottom plug, and with plane flush on non-return bottom plug, the valve rod with It is connected through a screw thread between plug, non-return bottom plug, and screw-thread fit junction is both provided with sealing ring.
In a kind of above-mentioned water discharge valve, on the tubular sleeve excircle end wall setting there are two in valve chamber The ring for the sealing liquid that wall is tightly connected, the ring for the sealing liquid described in two are respectively arranged at excircle end wall both sides up and down.Prevent discharging valve from existing When normal work, fluid is flowed out from apopore, causes to reveal.
In a kind of above-mentioned water discharge valve, the osculum is circumferentially uniformly distributed on the side wall of lower housing, and Osculum is rounded.Improve drainage efficiency when draining.
Compared with prior art, the utility model discharging valve is provided with tubular sleeve and check valve assembly, and the two is implemented in combination with Self-draining effect, have the advantages that efficiently brake, it is safe and reliable
