Description
technical field:
The utility model relates to a kind of leakage-proof type outlet valve, belongs to valve technology field.
background technique:
The working principle of traditional outlet valve is: when there being gas overflowing in system, gas can be climb along pipeline, finally be gathered in the peak of system, and outlet valve is generally all arranged on system peak, when gas enters the top that outlet valve valve pocket is gathered in outlet valve, along with increasing of gas in valve, pressure increase, when gas pressure is greater than system pressure, gas can make the water surface in chamber decline, floating drum declines with water level, opens relief opening; After gas drains, water level rises, floating drum also rises thereupon, close relief opening, but a lot of outlet valve, after often using, leaks outside if any easily producing after incrustation scale blocking exhaust port when particularly float-plane version outlet valve ubiquity uses in the market, and outlet valve is generally arranged on furred ceiling position, as cannot Timeliness coverage once leakage, during Sudden Leakage, can loss be brought, especially in factory building, the leakage hidden danger of manufacturing mechanism be happened occasionally.
summary of the invention:
Technical problem to be solved in the utility model is, provides a kind of leakage-proof type outlet valve, and to solve current outlet valve, particularly float-plane version outlet valve is because reveal and the loss that causes and security incident.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of leakage-proof type outlet valve, is provided with valve body, is provided with floating drum in described valve body, and described valve body is provided with valve gap.
In order to can better be vented, further, described valve gap be provided with smoke releasing cap, vertical direction be provided with gas-entered passageway to described valve gap, the side of described valve gap is provided with through hole.
In order to can conveniently connect, more further, be provided with worm structure in described through hole, described through hole communicates with gas-entered passageway, and the arranged outside of described through hole has step.
In order to prevent revealing, increase sealing, again further, described step place is provided with the seal ring of quality of rubber materials, the center of described smoke releasing cap is provided with runs through overall exhaust port, one end of described smoke releasing cap is provided with worm structure, and the other end is provided with leaning structure, and the screw thread of described worm structure is ZG screw thread.
In order to prevent the liquid stream that leaks out, further, described leaning structure is provided with outlet pipe.
Compared with prior art, usefulness of the present utility model is: provide a kind of novel leakage-proof type outlet valve, by being provided with worm structure on described valve gap, valve gap is provided with bonnet, described bonnet is provided with flexible pipe, when effectively can prevent outlet valve generation leakage by such structure, liquid is effectively discharged.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is plan view of the present utility model.
Fig. 2 is A place of the present utility model enlarged partial sectional view.
In figure: 1, valve body; 2, floating drum; 3, valve gap; 4, smoke releasing cap; 5, gas-entered passageway; 6, through hole; 7, worm structure; 8, step; 9, seal ring; 10, exhaust port; 11, outlet pipe.
embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail: a kind of leakage-proof type outlet valve according to Fig. 1 and Fig. 2, be provided with valve body 1, floating drum 2 is provided with in described valve body 1, described valve body 1 is provided with valve gap 3, described valve gap 3 is provided with smoke releasing cap 4, vertical direction is provided with gas-entered passageway 5 to described valve gap 3, the side of described valve gap 3 is provided with through hole 6, worm structure 7 is provided with in described through hole 6, described through hole 6 communicates with gas-entered passageway 5, the arranged outside of described through hole 6 has step 8, described step 8 place is provided with the seal ring 9 of quality of rubber materials, the center of described smoke releasing cap 4 is provided with runs through overall exhaust port 10, one end of described smoke releasing cap 4 is provided with worm structure 7, the other end is provided with leaning structure, described leaning structure is provided with outlet pipe 11, the screw thread of described worm structure 7 is ZG sealed pipe screw thread.
During use, first seal ring 9 is positioned over step 8 place, the screw thread of smoke releasing cap 4 is connected with the screw thread on valve gap 3, and press seal circle 9, be connected on smoke releasing cap 4 by outlet pipe 11, have water to overflow if had in outlet valve, water will flow in outlet pipe 11, by judging whether there are flowing out in outlet pipe 11, judge the quality of outlet valve.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
