Description

Be provided with the centre-pivoted butterfly valve of fluted disc fixing device
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device.
Background technique
Centre-pivoted butterfly valve is a kind of parts that are used for realizing pipe-line system break-make and flow control, in many fields such as oil, chemical industry, metallurgy, water power, obtains applying very widely.The structure characteristic of centre-pivoted butterfly valve is that valve rod axle center, butterfly plate center, body center are on same position.Simple in structure, easily manufactured.Common butterfly valve belongs to this type of.Shortcoming be due to butterfly plate and valve seat all the time in extruding, scraping state, resistance apart from large, quick abrasion.For overcoming extruding, scraping, guaranteeing that sealability, valve seat adopt rubber or teflon elastomeric material substantially.
Centre-pivoted butterfly valve is provided with fluted disc that can regulating valve inner fluid flow, and fluted disc is provided with scale, adjusts different scales and can regulate the size of fluid flow.In the process of using, there is sometimes fluted disc and made fluted disc lose the function that regulates fluid flow by collide unintentionally or naturally unclamp etc.
Summary of the invention
The purpose of this utility model is to provide a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, to solve the above-mentioned defect existing in prior art.
For realizing the purpose of this utility model, the utility model provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, comprise handle, fluted disc, valve rod, valve body, valve seat, flap, one end of described valve rod is fixed with handle, the other end penetrates in the axis hole of described valve body, between described handle and described valve body, be provided with fluted disc, described valve seat divides and is fixedly connected with valve body lower portion, described flap is fixed on described valve rod, also comprise fluted disc fixing device, described fluted disc fixing device is connected with described valve rod and fluted disc, for fixing described fluted disc at some scales.
Wherein, described fluted disc fixing device comprises fixed plate and bearing pin, and described fixed plate is provided with fixed plate axis hole and fixed hole, and described fixed plate axis hole is located at described fixed plate one end, fixedly sleeved on described valve rod; Described fluted disc is provided with and the corresponding fluted disc fixed hole of described fixed hole, and described fixed hole and described fluted disc fixed hole are fixed by bearing pin.
Wherein, described fixed hole is multiple, and correspondingly, the quantity of described fluted disc fixed hole is consistent with described fixed hole.
The utility model provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, by fluted disc fixing device is set, can make fluted disc be securely fixed on a certain scale, can not cause the scale of fluted disc arbitrarily to change, thereby affect the normal use of center line valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model fixed plate;
In figure, 1-handle, 2-fluted disc, 3-valve rod, 4-valve body, 5-valve seat, 6-flap, 7-fixed plate axis hole, 8-fixed hole, 9-fixed plate.
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.
The utility model provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, comprise handle, fluted disc, valve rod, valve body, valve seat, flap, one end of described valve rod is fixed with handle, the other end penetrates in the axis hole of described valve body, between described handle and described valve body, be provided with fluted disc, described valve seat divides and is fixedly connected with valve body lower portion, described flap is fixed on described valve rod, also comprise fluted disc fixing device, described fluted disc fixing device is connected with described valve rod and fluted disc, for fixing described fluted disc at some scales.
Wherein, described fluted disc fixing device comprises fixed plate and bearing pin, and described fixed plate is provided with fixed plate axis hole and fixed hole, and described fixed plate axis hole is located at described fixed plate one end, fixedly sleeved on described valve rod; Described fluted disc is provided with and the corresponding fluted disc fixed hole of described fixed hole, and described fixed hole and described fluted disc fixed hole are fixed by bearing pin.
Wherein, described fixed hole is multiple, and correspondingly, the quantity of described fluted disc fixed hole is consistent with described fixed hole.
The utility model provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, by fluted disc fixing device is set, can make fluted disc be securely fixed on a certain scale, can not cause the scale of fluted disc arbitrarily to change, thereby affect the normal use of center line valve.
As shown in Figure 1 and Figure 2, the fixed plate that the utility model provides, is provided with fixed hole and fixed plate axis hole.When using, described fixed plate axis hole is fixedly sleeved on valve rod, in the time of rotation valve rod regulating valve opening width size, described fixed plate rotates along with the rotation of valve rod, and when turning to the scale needing, the fixed hole of being located on fixed plate adapts with the fluted disc fixed hole position of being located on fluted disc, can two holes be passed by bearing pin, thereby fixed plate and fluted disc are fixed together, can not arbitrarily rotate, guaranteed the normal use of valve.
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.
