Abstract
The invention discloses a novel high-pressure flat gate valve which is characterized by comprising a valve bonnet (1), a valve stem (2), a high-performance elastic valve seat sealing ring (3), a valve body (4), a middle flange gasket (5), a valve seat (6), a valve plate (7) and a guide plate (8). The guide plate (8), the valve seat (4) and the high-performance elastic valve seat sealing ring (3) are mounted in the valve body (4), the valve plate (7) is mounted between the valve seat (6) and the high-performance elastic valve seat sealing ring (3), the valve stem (2) is mounted in the valve plate (7), the middle flange gasket (5) is arranged between the valve bonnet (1) and the valve body (4), the high-performance elastic valve seat sealing ring (3) is mounted on the valve seat (6), and tungsten is required to be sprayed on two sealing surfaces of the valve plate (7). The novel high-pressure flat gate valve has the advantages that vibration due to scouring when media are throttled is reduced, the corrosion resistance and the scouring resistance of the novel high-pressure flat gate valve are improved, a sealing effect is enhanced, and the service life of the novel high-pressure flat gate valve is prolonged.
Description
Technical field
The present invention relates to gate valve, be specifically related to the novel high-pressure plate valve.
Background technique
Plate valve application is wider, mainly is applicable to the conveying of the underground exploitation of oil, rock gas, mirabilite, saline solution and oil plant, gas pipe line.Conventional plate valve is in wavy spring and the sealing of O RunddichtringO for rear portion of valve seat, and there is certain defect in its sealing effect: the one, and when pressure medium is low, the sealing force of metallic sealing section is not enough to reach the effect of sealing; The 2nd, it is fragile that sealing surface of seat is subject to the valve body thermal distortion; The 3rd, when pressure medium is high, often keying can make sealing surface wear excessive, causes leaking.
Summary of the invention
The object of the invention is to: a kind of novel high-pressure plate valve is provided, at the valve seat rear portion, with high-performance elastic valve seat insert alternative wave spring and O RunddichtringO, seal, make the sealing surface of flashboard and valve seat remain fit-state, the tungsten process treating is sprayed on the surface of flashboard, has improved anticorrosive flushing resistance.
Technical solution of the present invention is: this novel high-pressure plate valve comprises valve gap, valve rod, high-performance elastic valve seat insert, valve body, middle flange gasket, valve seat, valve plate and guide plate, guide plate and valve seat and high-performance elastic valve seat insert are installed in valve body, between valve seat and high-performance elastic valve seat insert, valve plate is installed, valve rod is installed in valve plate, is provided with middle flange gasket between valve gap and valve body.
In novel high-pressure plate valve of the present invention, the high-performance elastic valve seat insert is installed on valve seat.
In novel high-pressure plate valve of the present invention, valve plate two sealing surfaces need be processed through spray tungsten.
Beneficial effect of the present invention is: wash away the vibration caused and improve anticorrosive flushing resistance while reducing the medium throttling, strengthen sealing effect, increase the service life.
The accompanying drawing explanation
Fig. 1 is the invention structural representation.
In figure: 1. valve gap, 2. valve rod, 3. high-performance elastic valve seat insert, 4. valve body, 5. in flange gasket, 6. valve seat, 7. valve plate, 8. guide plate.
Embodiment
As shown in Figure 1, this novel high-pressure plate valve comprises valve gap 1, valve rod 2, high-performance elastic valve seat insert 3, valve body 4, middle flange gasket 5, valve seat 6, valve plate 7 and guide plate 8, guide plate 8 and valve seat 4 and high-performance elastic valve seat insert 3 are installed in valve body 4, valve plate 7 is installed between valve seat 6 and high-performance elastic valve seat insert 3, valve rod 2 is installed in valve plate 7, is provided with middle flange gasket 5 between valve gap 1 and valve body 4.
In novel high-pressure plate valve of the present invention, high-performance elastic valve seat insert 3 is installed on valve seat 6.
In novel high-pressure plate valve of the present invention, 7 liang of sealing surfaces of valve plate need be processed through spray tungsten.
Beneficial effect of the present invention is: wash away the vibration caused and improve anticorrosive flushing resistance while reducing the medium throttling, strengthen sealing effect, increase the service life.
