Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-2, a kind of ceramic gate valve, comprise valve body 1, valve gap 2, valve rod 3 and handwheel 4, the middle part of valve body 1 is provided with the through fluid passage in left and right 5, the top of valve body 1 is provided with to downward-extension and the valve pocket 6 through with fluid passage 5, the top of valve pocket 6 is bolted valve gap 2, the top of valve gap 2 is provided with support 7, the top of support 7 is provided with nut 8, the front end of nut 8 is provided with oil hole 9, the internal slide of valve pocket 6 is provided with valve plate 10, the top of valve plate 10 connects valve rod 3 by tapered cylinder pin 11, handwheel 4 is threaded connection after the top of valve rod 3 is each passed through valve gap 2 and nut 8, be threaded connection between valve rod 3 and nut 8, the bottom end of described valve plate 10 is half globoidal structure, elastic block rubber 12 is provided with bottom valve pocket 6 below valve plate 10, the top of elastic block rubber 12 is provided with the half cambered surface pottery loose piece 13 cooperatively interacted with valve plate 10, the front panel of valve pocket 6 and rear sidewall are equipped with the first valve pocket ceramic plate 14, the left side wall of valve pocket 6 and right side wall are equipped with the second valve pocket ceramic plate 15, fluid passage 5 inwall of valve plate 10 both sides is equipped with ceramic path tube 16, the two side of valve plate 10 is equipped with valve plate ceramic plate 17.
Ceramic gate valve of the present utility model, the bottom underlay asbestos seal plate 18 of described valve gap 2.
Ceramic gate valve of the present utility model, the contacting point between described valve gap 2 and valve rod 3 is sealed by seal ring 19.
Ceramic gate valve of the present utility model, the inner end outer wall of described ceramic path tube 16 is all arranged with ceramic-seal ring 20, improves sealing effect.
Ceramic gate valve of the present utility model, described ceramic path tube 16 enclose 21 with the joint of valve body 1 by O shape and seals, and O shape is enclosed 21 and is used to regulate the sealing between ceramic path tube 16 and valve plate ceramic plate 17.When not installing, pottery path tube 16 can be lifted down, and when installation, ceramic path tube 16 can extrude to centre by the flange of valve both sides, thus O shape circle 21 is also extruded, and improves sealability.
Ceramic gate valve of the present utility model is when specifically using, handwheel is located on valve rod outer wall by thread bush, risen by rotation hand wheel band ovable valve stem or decline, and then drive valve plate to rise or decline, the half cambered surface pottery loose piece supported by elastic block rubber is provided with bottom the valve pocket of valve plate bottom, the radian of half cambered surface pottery loose piece is the same with the radian bottom valve plate, when valve plate is closed, circular arc bottom valve plate pushes down the circular arc of half cambered surface pottery loose piece, because elastic block rubber is quality of rubber materials, there is certain elasticity and sink.At this moment two ceramic-seal rings in the valve plate ceramic plate on valve plate and valve body seal, thus valve is closed.When valve plate is promoted; valve plate separates with half cambered surface pottery loose piece; now due to the rebound effect of elastic block rubber; half cambered surface pottery loose piece is popped up; until the half cambered surface pottery arc shaped surface of loose piece flushes with the cambered surface of the ceramic path tube in valve body latus rectum; the effect of this elastic block rubber is exactly that granule medium in anti-fluid accumulates and goes bottom valve pocket; improve the tightness of valve; the all ceramic embedded plate of the madial wall of valve pocket and the two side of valve plate, can adapt to have the medium of particle or iron powder, corrosive chemical medium, petroleum crude oil etc. in fluid.The design of this valve uses pressure rating to be 0.6MPa-4.0MPa.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
