Abstract
The invention discloses a center-line-type butterfly valve provided with a fluted disc fixing device. The center-line-type butterfly valve comprises a hand shank, a fluted disc, a valve rod, a valve body, a valve seat and a valve clack; one end of the valve rod is fixedly provided with the hand shank, and the other end of the valve rod penetrates through an axle hole of the valve body; the fluted disc is arranged between the hand shank and the valve body; the valve seat is fixedly connected with the lower part of the valve body; the valve clack is fixed on the valve rod; the center-line-type butterfly valve further comprises the fluted disc fixing device, and the fluted disc fixing device is connected with the valve rod and the fluted disc and used for fixing the fluted disc on a certain scale. The fluted disc fixing device includes a stator and a hinge pin, the stator is provided with a stator axis hole and a fixing hole, and the stator axis hole is formed in one end of the stator and fixedly connected to the valve rod in a sleeved mode. By arranging the fluted disc fixing device, the fluted disc can be fixed on a certain scale firmly, so that the scales of the fluted disc will not be changed randomly, and normal use of the center-line-type butterfly valve will not be affected.
Description
Technical field
The invention belongs to valve technology field, relate 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 the size that different scales can regulate 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 object of this invention 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 object of the present invention, the invention 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 fluted disc with described valve rod, 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 a plurality of, and correspondingly, the quantity of described fluted disc fixed hole is consistent with described fixed hole.
The invention provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, by fluted disc fixing device is set, can not cause the scale of fluted disc arbitrarily to change so that fluted disc is securely fixed on a certain scale, thereby affect the normal use of center line valve.

Embodiment
In order to make object of the present invention, technological scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be understood to specific embodiment described herein only in order to explain the present invention, be not limited to protection scope of the present invention.
The invention 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 fluted disc with described valve rod, 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 a plurality of, and correspondingly, the quantity of described fluted disc fixed hole is consistent with described fixed hole.
The invention provides a kind of centre-pivoted butterfly valve that is provided with fluted disc fixing device, by fluted disc fixing device is set, can not cause the scale of fluted disc arbitrarily to change so that fluted disc is securely fixed on a certain scale, thereby affect the normal use of center line valve.
As shown in Figure 1 and Figure 2, fixed plate provided by the invention, 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 pass by bearing pin Jiang Liangge hole, thereby fixed plate and fluted disc are fixed together, can not arbitrarily rotate, guaranteed the normal use of valve.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
