Description

A kind of chlorine cutoff valve
Technical field
The present invention relates to valves, and in particular to a kind of shut-off valve to shut off for chlorine.
Background technology
The medium flow direction of common valve is low in and high out, i.e., low level flows into high-order outflow, that is, as shown in the figure from left past It is right.When pipe medium pressure is excessive so that the liquid pressure below flap is this higher than the pressure medium above flap Flow direction can not live valve pass, that is, described interior leakage.It needs to provide a kind of new technical solution and be asked to solve above-mentioned technology Topic.
The content of the invention
The present invention provides a kind of chlorine cutoff valve, the original intention for designing this product is：The technology for solving background technology is asked Topic, enhances the leakproofness of valve, valves leakage will not be caused successfully to realize shutting off for medium, and the present apparatus is defeated in high-pressure medium Laborsaving convenience is opened in the case of sending.
The present invention provides following technical proposals：A kind of chlorine cutoff valve, including containing gland 1, filler 2, valve deck 3, valve Valve opening and closing component, the valve body 5 of bar 4, which is characterized in that the chlorine cutoff valve further includes air-flow and blocks component, the air-flow It blocks component and contains the first flap 6, the second flap 7, valve clack cover 8, the lower end activity of second flap 7 and the valve rod 4 connects It connects, the valve clack cover 8 is fixedly connected with 6 upper end of the first flap, and the valve rod 4 is screwed on 8 screw thread of valve clack cover, described First flap 6 is equipped with the first sealing ring 10, and the lower end of second flap 7 is equipped with the second sealing ring 11, and first flap 6 is set There is the 3rd sealing ring 12, the 3rd sealing ring 12 is connected with the valve body 5 and first sealing ring 10 and described second close Seal 11 connects, and the chlorine cutoff valve is closed；3rd sealing ring 12 is separated with the valve body 5 and first sealing ring 10 separate with second sealing ring 11, and the chlorine cutoff valve is open-minded, between first flap 6 and second flap 7 Annular chamber 13 is surrounded, first flap 6 offers the relief hole 14 being connected with the annular chamber 13, the chlorine cutoff valve Inlet of the medium 16 pressure medium it is higher than the pressure medium of the outlet of the medium 17 of the chlorine cutoff valve.The valve deck 3 Gasket 15 is equipped with the valve body junction.
Back seal seat 18 is equipped between the gland 1 and the valve rod 4.
Beneficial effects of the present invention.
1st, this product can allow medium to flow to high in and low out, that is, turn left as shown in the figure from the right side.In this way, valve is mounted on It, can be by means of the pressure of medium on pipeline so that valve closes tighter.
2nd, this product employs bivalve valve structure, excessive in pressure when avoiding commutation installation direct with common valve When, when valve needs to open, it could be opened with huge strength or situation about not opening occur.This valve needs to open When, due to the contact area very little of the second flap 7 and medium, pressure is small, therefore passes to 7 pressure of the second flap also very It is small, it is easy to open the second flap 7, medium achievees the purpose that pressure release by the relief hole on flap, so can be more easily Open valve.
3rd, seat bottom portion installs a back seal device so that when valve is opened to maximum position, medium is not from valve deck Portion reveals, and mitigates the pressure of filler.And back seal seat can be maintained easily with dismounting and change.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1：Gland 1, filler 2, valve deck 3, valve rod 4, valve body 5, the first flap 6, the second flap 7, valve clack cover 8, hole 9, First sealing ring 10, the second sealing ring 11, the 3rd sealing ring 12, annular chamber 13, relief hole 14, gasket 15, inlet of the medium 16, Outlet of the medium 17, back seal seat 18.
A kind of chlorine cutoff valve, including containing gland 1, filler 2, valve deck 3, the valve opening and closing component of valve rod 4, valve body 5, institute It states chlorine cutoff valve and further includes air-flow and block component, the air-flow blocks component and contains the first flap 6, the second flap 7, valve clack cover 8, second flap 7 is flexibly connected with the lower end of the valve rod 4, and the mode of flexible connection is that the lower end of valve rod 4 is equipped with T-shaped Structure, which is directly socketed on the second 7 second flap of flap 7 by the hole 9 of 7 side of the second flap itself to turn It is dynamic, without the axial play up and down along valve rod 4.The valve clack cover 8 is fixedly connected with 6 upper end of the first flap, described Valve rod 4 is screwed on 8 screw thread of valve clack cover, and first flap 6 is equipped with the first sealing ring 10, the lower end of second flap 7 Equipped with the second sealing ring 11, first flap 6 is equipped with the 3rd sealing ring 12, and the 3rd sealing ring 12 connects with the valve body 5 It connects and first sealing ring 10 is connected with second sealing ring 11, the chlorine cutoff valve is closed；3rd sealing ring 12 separate and first sealing ring 10 is separated with second sealing ring 11 with the valve body 5, and the chlorine cutoff valve is open-minded, Annular chamber 13 is surrounded between first flap 6 and second flap 7, first flap 6 offers and the annular chamber 13 relief holes 14 being connected, the pressure medium of the inlet of the medium 16 of the chlorine cutoff valve is than Jie of the chlorine cutoff valve The pressure medium of mass flow outlet 17 is high.The purpose so designed be so that, high pressure also for can carry out natural pressure shut off it is close Envelope, that is, pressure is formed to the first flap 6, guarantee is not revealed, and the present apparatus is fixedly connected with the valve with 4 upper end of valve rod by rotation Disk so that 4 own rotation of valve rod, under the action of thread fitting, driving stem does upward axial movement, works as valve as shown in the figure When door needs to open, due to the contact area very little of the second flap 7 and medium, pressure also very little, it is easy to open second Flap 7, medium achieve the purpose that pressure release by the relief hole 14 on the first flap 6, so can easily open valve.
The valve deck 3 is equipped with gasket 15 with the valve body junction.Ensure the air-tightness of this valve.
