Abstract
The utility model discloses the dismountable butterfly valve of a kind of structure, described butterfly valve comprises handle, valve body, nut, valve seat, flap, described handle and valve rod are integrated linkage structure, described handle and valve rod joint are fixedly connected with fixed plate, described fixed plate is fixedly connected with by described nut with described valve body, and described valve rod inserts in center hole and passes the fixed hole of described flap; Described valve seat is rubber material, and the external diameter of described valve seat is greater than the internal diameter of described valve body flap mounting hole, and the thickness of described valve seat is greater than the thickness of described valve body wall, and described flap is installed in described flap mounting hole; During dismounting, first described nut is turned on, extracted described valve rod, take off flap, drag lower described valve seat.Compared with prior art, its valve rod and handle are integrated, and valve seat and valve body are drive fit structure, simple in structure, easily dismounting, the working life that can improve butterfly valve, when certain parts of described butterfly valve break down, can relatively easily replace, saved equipment cost.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, relates in particular to the dismountable butterfly valve of a kind of structure.
Background technique
Valve is the controlling component in fluid delivery system, have cut-off, adjusting, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various, without unified, produce and use standard, production firm often goes to manufacture according to user's actual demand.
The utility model provides a kind of structure dismountable butterfly valve, in order to meet user's particular demands.
Summary of the invention
The purpose of this utility model provides a kind of structure dismountable butterfly valve, to meet user's specific user demand.
In order to realize the purpose of this utility model, the utility model provides a kind of structure dismountable butterfly valve, described butterfly valve comprises handle, valve body, nut, valve seat, flap, described handle and valve rod are integrated linkage structure, described handle and valve rod joint are fixedly connected with fixed plate, described fixed plate is fixedly connected with by described nut with described valve body, and described valve rod inserts in center hole and passes the fixed hole of described flap; Described valve seat is rubber material, and the external diameter of described valve seat is greater than the internal diameter of described valve body flap mounting hole, and the thickness of described valve seat is greater than the thickness of described valve body wall, and described flap is installed in described flap mounting hole; During dismounting, first described nut is turned on, extracted described valve rod, take off flap, drag lower described valve seat.
The utility model, compared with prior art, its valve rod and handle are integrated, and valve seat and valve body are drive fit structure, simple in structure, easily dismounting, the working life that can improve butterfly valve, when certain parts of described butterfly valve break down, can relatively easily replace, saved equipment cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-handle, 2-valve body, 3-nut, 4-valve seat, 5-flap.
Embodiment
In order to make the purpose of this utility model, technological scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of structure dismountable butterfly valve, described butterfly valve comprises handle, valve body, nut, valve seat, flap, described handle and valve rod are integrated linkage structure, described handle and valve rod joint are fixedly connected with fixed plate, described fixed plate is fixedly connected with by described nut with described valve body, and described valve rod inserts in center hole and passes the fixed hole of described flap; Described valve seat is rubber material, and the external diameter of described valve seat is greater than the internal diameter of described valve body flap mounting hole, and the thickness of described valve seat is greater than the thickness of described valve body wall, and described flap is installed in described flap mounting hole; During dismounting, first described nut is turned on, extracted described valve rod, take off flap, drag lower described valve seat.
The utility model, compared with prior art, its valve rod and handle are integrated, and valve seat and valve body are drive fit structure, simple in structure, easily dismounting, the working life that can improve butterfly valve, when certain parts of described butterfly valve break down, can relatively easily replace, saved equipment cost.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
