Abstract
The utility model relates to an abrasion-resistant ceramic gate valve without materials accumulated. A slag guiding port is formed in an outlet side of a valve body. A valve body outlet flow channel is designed to be in a streamline-shaped horn shape. A protective ceramic plate is arranged at the bottom of the valve body. Ceramic sealing pairs are respectively arranged on a valve seat and a gate plate. The valve seat is arranged on an inlet side of the valve body and is provided with an O-shaped ring. The gate plate is arranged between the valve seat and the outlet side of the valve body. A hard alloy sealing surface is welded on a wedge face of the gate plate in a piled mode. A valve rod is arranged inside the valve body and is movably connected with the gate plate. A valve cover is arranged above the valve body and a sealing cavity body is formed by the valve cover and the valve body. Due to the fact that the streamline-shaped horn-shaped valve body, media of the upper cavity of the valve body can be discharged out of the valve body smoothly, and accumulation of the materials on an upper cavity of the valve body can be avoided. A wedge-type gate plate structure enables a damaged sealing surface to compensate by self. Meanwhile, the sealing pairs adopt ceramic materials and are abrasion resistant and scratch resistant, service life of the valve is prolonged, and the abrasion-resistant ceramic gate valve without the materials accumulated is suitable for a serious-abraded slag-thick-liquid pipeline and valves which are provided with more coal slag and large-size particles and are under a hostile working condition.
Description
Technical field
The utility model belongs to valve field, relates to a kind of wear-resistant ceramic gate valve that does not accumulate material, is particularly useful for the slag slurry pipeline of serious wear, and lime-ash is more and with the valve of the bad working environments of larger solid particle.
Background technique
At present, Wedge gate valve on industrial pipeline, the concave structure of self-assembling formation between flashboard and valve body, be easy to deposit slag, the card ash, can cause the keying of valve not smooth like this, and accumulating between the sealing surface that can be clipped in flashboard and valve seat of the solid particle of valve body cavity bottom produces and leak, wearing and tearing appear in flashboard and sealing surface of seat very soon, and working life is short.
Summary of the invention
[0003] problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of wear-resistant ceramic gate valve that does not accumulate material is provided, the outlet side valve body has leads cinder notch, and lead the cinder notch opening towards outlet loudspeaker shape valve body, by offering the streamlined horn-like valve body of leading cinder notch, the medium of valve body epicoele is discharged valve body smoothly, prevent that material from accumulating at the valve body epicoele, the wedge-type flashboard structure makes impaired sealing surface self compensation, and sealing pair adopts stupalith simultaneously, wear-resistant, scrape resistence, extended working life of valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of wear-resistant ceramic gate valve that does not accumulate material provided according to the utility model, comprise valve body, valve seat, flashboard, valve rod, valve gap, described valve outlet side offers leads cinder notch, the valve outlet runner is made as streamlined horn shape, the protection ceramic plate is equipped with in the valve body bottom, the ceramic seal pair is housed respectively on valve seat and flashboard, valve seat is contained in the valve body suction side, O type circle is housed on valve seat, flashboard is contained between valve seat and valve outlet side, on the flashboard wedge surface, built-up welding has the cemented carbide sealing surface, valve rod is contained in valve body, flashboard is connected with valve handle activity, valve gap is contained in the valve body top and forms seal chamber with valve body.
The utility model compared with prior art has significant advantage and beneficial effect:
Lead cinder notch and open to the streamlined horn-like valve body of outlet side due to the outlet side of the utility model valve body, the solid dielectric of valve body epicoele can be discharged valve body smoothly by the cinder notch gap of leading on the outlet side valve body, reaches the purpose of valve body body cavity without jam and material accumulation.Simultaneously, in order to solve the problem of valve seal surface wear, the self compensation wear extent but employing wedge-type flashboard structure is connected with valve handle activity, the main sealing pair dress of flashboard engineering ceramics, the secondary pile-up welding hard alloy of auxiliary seal, thoroughly solved the wear problem of valve, be greatly improved the working life of valve.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, valve body 2, valve seat 3, flashboard 4, ceramic seal pair 5, O type circle 6, valve rod 7, valve gap 8, cemented carbide sealing surface 9, lead cinder notch 10, valve outlet runner 11, protection ceramic plate.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the embodiment that foundation the utility model is provided, structure, feature and effect thereof, be described in detail as follows.
A kind of wear-resistant ceramic gate valve that does not accumulate material as shown in Figure 1, comprise valve body, valve seat, flashboard, valve rod, valve gap, described valve body 1 outlet side offers leads cinder notch 9, valve outlet runner 10 is made as streamlined horn shape, lead the cinder notch opening towards outlet loudspeaker shape valve body, protection ceramic plate 11 is equipped with in the valve body bottom, on valve seat 2 and flashboard 3, ceramic seal pair 4 is housed respectively, valve seat is contained in the valve body suction side, O type circle 5 is housed on valve seat, flashboard is contained between valve seat and valve outlet side, on the flashboard wedge surface, built-up welding has cemented carbide sealing surface 8, valve rod 6 is contained in valve body, flashboard is connected with valve handle activity, when flashboard is mobile on the vertical pipe direction with valve rod, can move by parallel channels direction trace.Valve gap 7 is contained in the valve body top and forms seal chamber with valve body.
Working principle:
Valve rod 6 can be slided under external force, because valve rod is connected with flashboard 3, the motion of valve rod drives the motion of flashboard, when valve rod moves upward, flashboard breaks away from the runner of valve body, make valve open, medium reaches the purpose of circulation by valve, when valve rod moves downward, the wedge-type flashboard faces down along auxiliary seal, to the suction side motion until fit with valve seat, make valve closing, the auxiliary seal face helps pottery to realize the single face forced seal, even at pressure under lower operating mode, the active force that also can rely on wedge-type flashboard self-tightening to produce is realized the sealing of ceramic seal circle.The outlet side of valve body is led cinder notch and is opened to the streamlined horn-like valve body of outlet side, both made to have dust stratification to exist in valve closing, also can not clamp-on sealing surface but can be shifted onto on the slope of outlet by flashboard, will under throttling action, naturally be blown away once open and close, reach the purpose of valve body body cavity without jam and material accumulation.
