Abstract
The utility model provides a water seal butterfly valve, which comprises a valve body, a butterfly plate, a sealing ring, a valve shaft and a pressure plate. The sealing ring is arranged on butterfly plate through pressure plate and a valve seat is positioned on the inner cavity of the valve body to contact with the sealing ring, while the sealing ring is divided into a left sealing ring and right sealing ring that are respectively positioned on the butterfly plate through a left pressure plate and a right pressure plate; an annular groove is also arranged on valve seat between the left and right sealing rings, while the upper part and lower part of valve body are respectively drilled with a hole to be communicated with the annular groove; and a pressure regulating valve and an upper closing valve are arranged on the upper hole, while a lower closing valve is arranged on the lower hole. The utility model has the beneficial effects as follows: the valve is simple in structure, convenient for processing, notable for saving water, good in water seal effect and reliable in seal.
Description
Affiliated technical field
The utility model relates to a kind of butterfly valve apparatus, especially a kind of Water seal butterfly valve.
Background technique
The Water seal butterfly valve of metallurgy industry coal gas system use at present adopts bivalve axle, two butterfly plate form usually, forms the sealing water cavity between the double butterfly plate, realizes water seal, and two valve shafts are connected with connecting rod by swing arm, are driven by same drive unit.Owing to adopt the two butterfly plate forms of bivalve axle, the valve mechanism complexity, water consumption is big, because double butterfly plate is driven by same drive unit, unavoidably produces synchronization error in addition, can not be guaranteed repeatedly moving the sealability of late gate.
Summary of the invention
For the water consumption that overcomes the existing Water seal butterfly valve of metallurgy industry is big, the deficiency of valve seal poor performance, the utility model provides a kind of Water seal butterfly valve.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of Water seal butterfly valve, comprise valve body, butterfly plate, seal ring, valve shaft, pressing plate, seal ring is installed on the butterfly plate by pressing plate, valve seat is arranged on the body cavity, contact with seal ring, seal ring is divided into left seal ring and right seal ring, be installed on the butterfly plate by left pressing plate and right pressing plate respectively, on the valve seat between left seal ring and the right seal ring, also have circular groove, valve body top is drilled with the hole respectively with the bottom and communicates with circular groove, and pressure regulator valve and last cut-off valve are housed on the last hole, and cut-off valve is equipped with down in following hole.
The beneficial effects of the utility model are that valve mechanism is simple, are convenient to processing, and water saving is remarkable, and water seal is effective, and valve seal is reliable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Among the figure: 1. go up cut-off valve; 2. pressure regulator valve; 3. hole; 4. valve seat; 5. circular groove; 6. right seal ring; 7. left seal ring; 8. right pressing plate; 9. left pressing plate; 10. butterfly plate; 11. valve shaft; 12. valve body; 13. following cut-off valve.
Embodiment
As shown in Figure 1, a kind of Water seal butterfly valve, comprise valve body 12, butterfly plate 10, valve shaft 11, seal ring is installed on the butterfly plate 10 by pressing plate, on valve body 12 inner chambers valve seat 4 is arranged, contact with seal ring, seal ring is divided into left seal ring 7 and right seal ring 6, be installed on the butterfly plate 10 by left pressing plate 9 and right pressing plate 8, also have circular groove 5 on the valve seat 4 between left seal ring 7 and the right seal ring 6, valve body 12 tops are drilled with hole 3 respectively with the bottom and communicate with circular groove 5, pressure regulator valve 2 and last cut-off valve 1 are housed on the last hole 3, and cut-off valve 13 is equipped with down in following hole 3.When needing water seal, valve shaft 11 drives butterfly plate 10 and makes valve closing, close down cut-off valve 13, open cut-off valve 1, water enters the water seal chamber that is formed by circular groove 5 on left seal ring 7 and right seal ring 6 and the valve seat 4 by the hole on the valve body 12 3, regulate pressure regulator valve 2, reach the water seal pressure of design, the sealing sealing.When opening valve, close earlier and close cut-off valve 1, open down cut-off valve 13, water is put totally, again with valve open.
Claims (1)
1, a kind of Water seal butterfly valve, comprise valve body, butterfly plate, seal ring, valve shaft, pressing plate, seal ring is installed on the butterfly plate by pressing plate, valve seat is arranged on the body cavity, contact with seal ring, it is characterized in that: described seal ring is divided into left seal ring and right seal ring, be installed on the butterfly plate by left pressing plate and right pressing plate, on the valve seat between left seal ring and the right seal ring, also have circular groove, valve body top is drilled with the hole respectively with the bottom and communicates with circular groove, modulating valve and cut-off valve are housed on the last hole, on the following hole cut-off valve are housed.
