Description
Technical field
The utility model relates to a kind of all-plastic membrane valve of irregular barrier film.
Background technique
Membrane valve is one of charge valve commonly used in industrial stokehold.Membrane valve septation is important component, also be very easy to consume simultaneously, because existing barrier film is all fixing plane structure, the contraction operation of self cannot be carried out when pressurized, so just easily there is the excessive situation of pressurized, produce unnecessary consume, reduce outside working life, also results in the reduction of stability; Existing membrane valve is all directly think that barrier film is exerted pressure by valve rod, area due to valve rod is less than the area of barrier film, so just greatly reduce sealing effect during membrane valve operation, the direct contact of valve rod simultaneously also allows barrier film be more prone to be damaged, in addition, in existing membrane valve, the parts major part such as valve rod is all the stainless steel adopted, and more than like this manufacture cost that adds, also there will be situations such as getting rusty.
Model utility content
The utility model mainly solves the technical problem existing for prior art, thus provides that a kind of good stability, sealing effect are good, usability is excellent, low cost of manufacture, and the all-plastic membrane valve of the irregular barrier film of long service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The all-plastic membrane valve of a kind of irregular barrier film of the present utility model, forms primarily of handwheel, valve rod, captive nut, upper valve body, lower valve body, barrier film, flap, valve gap and fixed block; Described handwheel is positioned at the top of valve gap; Described fixed block runs through handwheel and is connected with valve gap; Described valve rod is positioned at the inside of valve gap; Described captive nut is positioned on valve rod; Described flap is positioned at the below of captive nut; Described upper valve body is positioned at the below of valve gap; Described barrier film is positioned at the below of flap; Described lower valve body is positioned at the below of barrier film; Described barrier film is concave structure; Described barrier film is provided with barrier film recess; Described valve rod one end is connected with handwheel, and the other end is connected with barrier film; The end that described valve rod is connected with barrier film is bifurcation structure.
As preferably, described barrier film is circular overall, and intermediate portion caves inward.
As preferably, described flap has 2, and symmetry is positioned at the both sides of valve rod.
As preferably, the width of described captive nut is greater than the width of valve rod.
As preferably, the width of described barrier film equals the width of valve body.
As preferably, the width of described lower valve body is greater than the width of upper valve body.
The beneficial effects of the utility model are: because the all-plastic membrane valve of irregular barrier film is provided with barrier film recess, allow barrier film open and close time can with caving in, plane structure unlike barrier film traditionally, the activity of self cannot be carried out, it is excessive that such barrier film is easy to pressurized when operation, cause consume, reduce working life, improve stability during use simultaneously; The design of captive nut allows barrier film effectively can avoid directly being subject to the pressure of valve rod, avoid the situation that local heating deforms, improve further outside working life, also effectively improve the sealing effect of membrane valve, the General Promotion usability of membrane valve; In addition, this kind of membrane valve adopts all-plastic material, allows outside manufacture cost significantly reduces, more effectively can also avoid situations such as being corroded during operation and getting rusty, improve working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural drawing of the all-plastic membrane valve of a kind of irregular barrier film of the utility model;
Fig. 2 is the structural drawing of the all-plastic membrane valve septation of a kind of irregular barrier film of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model
As shown in Figure 1 to Figure 2, a kind of all-plastic membrane valve of irregular barrier film, forms primarily of handwheel 1, valve rod 2, captive nut 3, upper valve body 4, lower valve body 5, barrier film 6, flap 7, valve gap 8 and fixed block 9; Described handwheel 1 is positioned at the top of valve gap 8; Described fixed block 9 runs through handwheel 1 and is connected with valve gap 8; Described valve rod 2 is positioned at the inside of valve gap 8; Described captive nut 3 is positioned on valve rod 2; Described flap 7 is positioned at the below of captive nut 3; Described upper valve body 4 is positioned at the below of valve gap 8; Described barrier film 6 is positioned at the below of flap 7; Described lower valve body 5 is positioned at the below of barrier film 6; Described barrier film 6 is concave structure; Described barrier film 6 is provided with barrier film recess 61; Described valve rod 2 one end is connected with handwheel 1, and the other end is connected with barrier film 6; The end that described valve rod 2 is connected with barrier film 6 is bifurcation structure.
Described barrier film 6 is circular overall, and intermediate portion caves inward.Described flap 7 has 2, and symmetry is positioned at the both sides of valve rod 2.The width of described captive nut 3 is greater than the width of valve rod 2.The width of described barrier film 6 equals the width of valve body 4.The width of described lower valve body 5 is greater than the width of upper valve body 4.
In use, after opening membrane valve by handwheel 1, valve rod 2 is under pressure and carries out operation the all-plastic membrane valve of this kind of irregular barrier film, and captive nut 3 moves down thereupon, and flap 7 is connected with captive nut 3, and flap 7 drives barrier film 6 to open subsequently; When after closedown membrane valve, captive nut 3 moves up, and is not connected with flap 7, and flap 7 is not exerted pressure to barrier film 6, and namely barrier film 6 closes.
The beneficial effects of the utility model are: because the all-plastic membrane valve of irregular barrier film is provided with barrier film recess, allow barrier film open and close time can with caving in, plane structure unlike barrier film traditionally, the activity of self cannot be carried out, it is excessive that such barrier film is easy to pressurized when operation, cause consume, reduce working life, improve stability during use simultaneously; The design of captive nut allows barrier film effectively can avoid directly being subject to the pressure of valve rod, avoid the situation that local heating deforms, improve further outside working life, also effectively improve the sealing effect of membrane valve, the General Promotion usability of membrane valve; In addition, this kind of membrane valve adopts all-plastic material, allows outside manufacture cost significantly reduces, more effectively can also avoid situations such as being corroded during operation and getting rusty, improve working life.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
