A steam jettron butterfly valve, belongs to valve technology field.It comprises valve body, is arranged on the integral type valve seat on valve body and is arranged on the valve rod in valve body, in described valve seat, be equipped with plate member, described plate member comprises valve plate, valve plate lid and is fixedly installed on the rubber base between valve plate, valve plate lid, between described rubber base and valve seat, form sealing, described valve plate is fixedly connected with valve rod, and described valve rod connects actuator.Above-mentioned a kind of steam jettron butterfly valve, simple in structure, reasonable in design, by integral type valve seat on rubber base and valve body, form soft and hard seal, sealability is strengthened; Gap between valve rod and valve body replaces filler by the O type circle arranging on valve rod, significantly improve the sealability between valve rod and valve body, thereby also reduce friction, reduce switch moment, extend the rubber base life-span, prevent that valve switch moment is excessive, damage sealing surface.

Description

A kind of steam jettron butterfly valve
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of steam jettron butterfly valve.
Background technique
Jettron butterfly valve, adapted air cylinder driven actuator, cuts off and flowing steam medium, has the advantages such as steering force is large, valve body is novel in design, flow resistance is little, rated flow coefficient is large, sealability is good.Being widely used in oil, chemical industry, light textile, food, bubble moulds etc. during the production process of each industrial department automatically controls and exchange with telecontrol.
In recent years, domestic valve industry develop rapidly, the product structure type of each valve producer emerges in an endless stream.But domestic existing jettron butterfly valve valve is heavy, volume is large, and difficulty of processing is large, dismounting inconvenience, and exist sealability not good, the shortcomings such as the easy damage of sealing surface.
Model utility content
The problem existing for prior art, the purpose of this utility model is that design provides the technological scheme of a kind of steam with jettron butterfly valve.
Described a kind of steam jettron butterfly valve, comprise valve body, be arranged on the integral type valve seat on valve body and be arranged on the valve rod in valve body, it is characterized in that being equipped with plate member in described valve seat, described plate member comprises valve plate, valve plate lid and is fixedly installed on the rubber base between valve plate, valve plate lid, between described rubber base and valve seat, form sealing, described valve plate is fixedly connected with valve rod, and described valve rod connects actuator.
Described a kind of steam jettron butterfly valve, is characterized in that described valve plate, valve plate cover and rubber base is fixed by the cross recessed countersunk head sscrew arranging.
Described a kind of steam jettron butterfly valve, the valve plate described in it is characterized in that and valve rod are fixed by the fluting flush end Cock screw, locked spacer and the hexagon nut that arrange.
Described a kind of steam jettron butterfly valve, is characterized in that described valve rod is provided with one group of O type groove, is provided with O type circle in described O type groove.
Described a kind of steam jettron butterfly valve, is characterized in that described valve rod connects actuator by the connecting rod arranging, and is provided with dustproof seal ring between described connecting rod and actuator.
Above-mentioned a kind of steam jettron butterfly valve, simple in structure, reasonable in design, by integral type valve seat on rubber base and valve body, form soft and hard seal, sealability is strengthened; Gap between valve rod and valve body replaces filler by the O type circle arranging on valve rod, significantly improve the sealability between valve rod and valve body, thereby also reduce friction, reduce switch moment, extend the rubber base life-span, prevent that valve switch moment is excessive, damage sealing surface.
Accompanying drawing explanation
Fig. 1 is general assembly structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of plate member in the utility model;
Fig. 4 is the structural representation of rubber base in the utility model;
Fig. 5 is the structural representation of valve rod in the utility model.
In figure: 1-valve body; 2-rubber base; 3-valve plate lid; 4-valve plate; 5-cross recessed countersunk head sscrew; 6-fluting flush end Cock screw; 7-locked spacer; 8-hexagon nut; 9-valve rod; 901-O type groove; 10-O type circle; 11-connecting rod; 12-dustproof seal ring; 13-actuator.
Embodiment
Below in conjunction with Figure of description, further illustrate the utility model.
As shown in Figure 1, a kind of steam consists of valve body part and actuator 13 with jettron butterfly valve, is connected between the two by support.Wherein actuator 13 is to be main body by two gas circuit cylinders, and the source of the gas signal pressure of accepting two position four-way solenoid valves control outputs is power, by control unit, changes airflow direction, and actuator's 13 actuating valve bodies divide does to open and close motion.
As shown in Figure 2, valve body is divided and is comprised valve body 1, is arranged on the integral type valve seat on valve body 1 and is arranged on the valve rod 9 in valve body 1.As shown in Figure 3, in valve seat, be equipped with plate member, plate member comprises valve plate 4, valve plate lid 3 and is fixedly installed on the rubber base 2 between valve plate 4, valve plate lid 3, and valve plate 4, valve plate lid 3 and rubber base 2 are specifically fixed together by the cross recessed countersunk head sscrew 5 arranging.Rubber base 2 structures as shown in Figure 4.After plate member and valve seat coordinate, form soft and hard seal, sealability is strengthened.Valve plate 4 in plate member is fixing with valve rod 9 by the fluting flush end Cock screw 6, locked spacer 7 and the hexagon nut 8 that arrange.Wherein locked spacer 7 has and prevents from washing away at medium the function that slot in process flush end Cock screw 6 and hexagon nut 8 get loose.As shown in Figure 5, valve rod 9 is provided with one group of O type groove 901, is provided with O type circle 10 in O type groove 901.Between gap between valve rod 9 and valve body 1, adopt O type circle 10 to replace filler, significantly improve the sealability between valve rod 9 and valve body 1, thereby also reduce friction, reduce switch moment, extend 2 life-spans of rubber base.Valve rod 9 connects actuator 13 by the connecting rod 11 arranging, and between connecting rod 11He actuator 13, is provided with dustproof seal ring 12.Dustproof seal ring 12 can effectively prevent that dust and dust from, in valve opening or closing process, avoiding being brought in valve, affects the usability of valve.
During work, actuator's 13 band ovable valve stems 9 rotate, and under valve rod 9 rotates, drive plate member to open and close on valve seat.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
