Abstract

The utility model relates to an eccentric butterfly valve, which includes a valve body, wherein a valve seat is arranged on the valve body. The eccentric butterfly valve is characterized in that the valve seat and the valve body are separately connected, for example, a pressure block is arranged on the valve seat and fixed on the valve body through a bolt. Through changing the integral forming structure of the valve body and the vale seat into the separate structure, the eccentric butterfly valve can realize the function of replacing the valve seat independently, thereby facilitating cost reduction.

Description

A kind of eccentric-butterfly-valve
Technical field
The utility model relates to a kind of butterfly valve, specifically is a kind of eccentric-butterfly-valve.
Background technique
On industrial pipelines such as metallurgy, electric power, petrochemical industry and plumbing and urban construction, as regulating flow and the effect of blocking fluid, eccentric-butterfly-valve has obtained using widely; Eccentric-butterfly-valve mainly is made of component such as valve rod, valve seat, valve body and spools, because eccentric-butterfly-valve in use is subjected to washing away of pipeline inner fluid and rubs through regular meeting, especially it mainly plays the effect of blocking or changing direction of flow, therefore after accumulation through the certain hour section, the wearing and tearing of component will be very serious, need change or keep in repair, wherein the most serious position of wearing and tearing mainly shows valve seat part; And in the prior art, because the valve seat and the valve body of eccentric-butterfly-valve just are cast on together in process of production, therefore the structure that both are formed in one also has to carry out integral replacing when just needing to change valve seat, and user cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of eccentric-butterfly-valve structure of effective reduction eccentric-butterfly-valve operation and maintenance cost.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of eccentric-butterfly-valve comprises valve body, has valve seat on the valve body, and its characteristics are that described valve seat is that separated type is connected with valve body.
As the further improvement of the technical program, can by on described valve seat, be pressed with briquetting and by screw on valve body.
As the further improvement of the technical program, described briquetting is an annular.The ring footpath of this briquetting adapts with the caliber size of valve seat present position.
Adopt the eccentric-butterfly-valve of technique scheme, change to separate type, make and to handle flexibly according to the abrasion condition of valve seat position that realization can be changed the function of valve seat separately, helps reducing cost by integrated formed structure with valve body and valve seat.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model being done one describes in detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With the three eccentric butterfly valve is example, and three eccentric butterfly valve as shown in Figure 1 comprises valve body 1, valve seat 3, spool 4.Wherein valve seat 3 and valve body 1 are separation structure, and wherein valve seat 3 is positioned at the valve seat mounting point, are compressed by briquetting 11 on it, and are fixed on the valve body 1 by screw 11.
After valve seat 3 is worn, only need unloads screw 11 and change new valve seat and get final product, thereby solve eccentric-butterfly-valve of the prior art, the defective that adopts one-body molded technology manufacturing to be brought owing to valve seat and valve body.
Wherein briquetting 11 is arranged to and the adaptive annular of valve seat 3 shapes, and its ring footpath caliber size best and the valve seat present position adapts.
The above-mentioned eccentric-butterfly-valve that the utility model provides, structure when separating by valve body and valve seat one-body molded transform as is assembled when being necessary, and then is helped reducing production costs, and is convenient to change.
