Abstract

A taper valve includes a valve body, a sealing valve seat embedded into the flow passage of the valve body, and a conical valve clack positioned in the of flow passage of the valve body, the body of the conical valve clack is embedded with a sealing ring matched with the sealing valve seat. The internal ring surface of the sealing valve seat is the anti-wear rubber sealing ring with conical ring structure and is embedded in a sealing ring trough processed in the flow passage of the valve body by a press ring; the external ring surface of the sealing ring embedded on the taper valve clack body is a ceramic sealing ring with the conical ring structure; the ceramic sealing ring is pressed and arranged in the sealing ring trough processed on the valve clack body by a press ring.

Description

A kind of mitre velve

The utility model relates to a kind of valve, relates to a kind of mitre velve that is used to carry particle or granular material specifically.

Mitre velve is a kind of valve that is usually used in the air-transport systems such as pulverized fuel ash, cement or flour, its valve flowing channel is a funnel-shaped structure, the flap that is positioned at runner is a cone structure, and the sealing between valve flowing channel and flap is to realize by the round rubber seal valve seat and the closely cooperating of flap male cone (strobilus masculinus) that are inlaid in the valve flowing channel.Because the medium that this valve is carried mostly is particle or powdery dry material; the reason of seal form and material material in addition; in the valve closing process; very easily press from both sides the pad fed sheet of a media between sealing surface; thereby cause partially sealed not tight; and the leakage that is entrained with media particle can make leakage enlarge rapidly under the impact wear effect of air blast, until seal failure.

The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, starts with from changing its sealing configuration form and material material, thereby a kind of mitre velve with good abrasion resistance is provided.

The purpose of this utility model can realize by following measure:

Mitre velve of the present utility model comprises valve body, is inlaid in the seal valve seat in the valve flowing channel, is positioned at the taper valve that is embedded with the seal ring that matches with seal valve seat on valve flowing channel and its body; Described seal valve seat is that its inner ring surface is the abrasive rubber seal ring of conical ring structure, and is inlaid in the closure gasket groove that processes in the valve flowing channel by pressure ring; The seal ring that is inlaid on the taper valve body is that its outer ring surface is the ceramic-seal ring of conical ring structure, and this ceramic-seal ring is fitted in the closure gasket groove that processes on the flap body by pressure ring.

Because the sealing means that the utility model adopts the inside and outside conical surface to match on sealing configuration, and employing high-strength abrasion-proof stupalith and the mutual close contact relation of joining of the abrasive rubber material with certain toughness, this just makes the utility model not only can effectively reduce the probability of folder pad fed sheet of a media between sealing pair in closing closed procedure, can guarantee to have under the precursor of good sealing elasticity and impact resistance between its sealing pair again simultaneously, its intensity and wear resistance are improved, finally reach the purpose that improves valve working life, reduces the breakdown maintenance rate.

Accompanying drawing is a plan view of the present utility model.

The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):

As shown in the figure, mitre velve of the present utility model comprises funnel shape valve body (1), the employing that is inlaid in the valve flowing channel has the seal valve seat (4) that rubber material well wear-resisting, ageing-resistant performance is made, and is positioned at the taper valve (2) that is embedded with the ceramic-seal ring (3) that matches with seal valve seat (4) on valve flowing channel and its body; Described seal valve seat (4) is that its inner ring surface is the rubber seal ring of conical ring structure, and is inlaid in the closure gasket groove that processes in the valve flowing channel by pressure ring (5); The seal ring (3) that is inlaid in taper valve (2) body awl bottom position is that its outer ring surface is the conical ring structure ceramic-seal ring of (being the close fit relation between the inner conical surface of this male cone (strobilus masculinus) and seal valve seat), and this ceramic-seal ring is fitted in bottom the flap body awl in the closure gasket groove that processes by pressure ring (6).

Claims

1, a kind of mitre velve, it comprises valve body (1), be inlaid in the seal valve seat (4) in the valve flowing channel, be positioned at the taper valve (2) that is embedded with the seal ring (3) that matches with seal valve seat on valve flowing channel and its body, it is characterized in that: described seal valve seat (4) is that its inner ring surface is the abrasive rubber seal ring of conical ring structure, and is inlaid in the closure gasket groove that processes in the valve flowing channel by pressure ring (5); The seal ring (3) that is inlaid on taper valve (2) body is that its outer ring surface is the ceramic-seal ring of conical ring structure, and this ceramic-seal ring is fitted in the closure gasket groove that processes on flap (2) body by pressure ring (6).
