Abstract
The utility model belongs to the valve field is to the easy deposition of current slide valve runner and a pottery double -gate plate valve who provides, including valve body, valve rod, valve gap, valve plate, filler mechanism, support and hand wheel, the valve plate includes the board of carving of ceramic valve plate and fixed ceramic valve plate, and ceramic valve plate is installed at the entrance point towards the valve body, and the valve body includes steel valve body and ceramic valve body, and the inner wall of steel valve body is placed in to ceramic valve body. Be equipped with the valve plate seat between board and the ceramic valve plate carving, have the sunken part of holding the ceramic plate on the valve plate seat. Have the arch of taking the external screw thread on the valve plate seat, have a through -hole that supplies this arch to pass on carving the board, the arch runs through carves through nut locking behind the board. The utility model discloses simple structure, with valve body inner chamber design for ceramic material, its smooth finish is better, the difficult jam, and resistantly wash away, the wearability is good.
Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of ceramic double flap valve.
Background technique
What the runner of existing gate valve and flashboard all adopted is that metal material is made, and the friction factor of the runner that metal material is made and flashboard is large, easy dust stratification, thus easily results in blockage.
Model utility content
The purpose of this utility model is the one pottery double flap valve provided for the easy dust stratification of existing gate valve runner.
The utility model is achieved by the following technical solution:
Pottery double flap valve, comprise valve body, valve rod, valve gap, valve plate, filling body, support and handwheel, what described valve plate comprised ceramic valve plate and fixing ceramic valve plate carves plate, pottery valve plate is arranged on towards the entrance point of valve body, valve body comprises steel valve body and ceramic valve body, and ceramic valve body is placed in the inwall of steel valve body.
Be provided with valve plate seat carving between plate and ceramic valve plate, valve plate seat have the depression part holding ceramic plate.
Described valve plate seat has the externally threaded projection of a band, plate has a through hole passed for this projection carving, projection run through carve plate after pass through nut check.
The steel valve body of one end that valve body entrance point contacts with valve plate has the depression part of ring-type, the ceramic valve body matched with it has the annular projection with the depression part phase clamping of ring-type.
The beneficial effects of the utility model: the utility model structure is simple, and body cavity is designed to stupalith, its degree of finish is better, not easily blocks, and resistance toly to wash away, wear resistance is good.Bracing type double-flashboard sealing configuration, two way sealed during valve closing, the utility model structure is simple, with low cost, reliable performance, and output torque is large, and this valve aims at pneumatic ash removal system design, has that switching motion is reliable, to start load little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, pottery double flap valve, comprise valve body, valve rod 1, valve gap 2, valve plate, filling body, support 3 and handwheel 4, filling body comprises condiment gland 5, filler 6, valve gap 2 has the depression part holding filler 6, filler 6 is filled in the depression part of valve gap 2, Gland 5 is arranged on valve gap 2, valve gap 2 connects handwheel 4 by support 3, it should be noted that, what described valve plate comprised ceramic valve plate 7 and fixing ceramic valve plate 7 carves plate 8, pottery valve plate 7 is arranged on towards the entrance point of valve body, valve body comprises steel valve body 9 and ceramic valve body 10, ceramic valve 10 body is placed in the inwall of steel valve body 9.
It should be noted that further and be provided with valve plate seat 11 carving between plate 8 and ceramic valve plate 7, valve plate seat 11 has the depression part holding ceramic plate.Described valve plate seat 11 has a band externally threaded protruding 12, plate 8 has a through hole passed for this projection 12 carving, protruding 12 run through carve plate 8 after locked by nut 13.The steel valve body of one end that valve body entrance point contacts with valve plate has the depression part of ring-type, the ceramic valve body matched with it has the annular projection 14 with the depression part phase clamping of ring-type.The setting of steel valve body annular recess part and ceramic valve body annular projection is the connection tightness in order to improve between the two, makes both come off easily.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
