Abstract
The utility model belongs to the technical field of valves, and in particular relates to a single-acting pressure lever type pinch valve. The pinch valve mainly comprises a hand wheel, a valve shaft, a valve cap, a valve body and a valve clack, wherein the hand wheel is in key connection with the end of the valve shaft penetrating the valve cap, and the other end of the valve shaft is in threaded connection with the valve clack. The pinch valve is characterized in that the valve clack is in sliding connection with an upper cavity of the valve body positioned below the valve cap; the top of the valve clack is shaped like a circular arc camber which is matched with the cross section of an inner cavity of the valve body; and the inner cavity of the valve body is perpendicular to the upper cavity of the valve body and is provided with a rubber sleeve with the diameter identical to that of the inner cavity of the valve body. The pinch valve has the benefits as follows: the design is reasonable; the structure is simple and adopts a straight-flow passage, so as to avoid flow resistance; and according to the characteristics of media, the rubber sleeve made of different rubber materials can be selected to partition the inner cavity of the valve body from an inner cavity of the valve cap and driving members, so that such parts as the valve shaft, the valve clack and the like above the rubber sleeve can be immune from the media corrosion, a filler sealing structure is not required, and the media leakage is avoided, which can greatly improve the service life of the valve.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of single action pressure bar type pinch valve.
Background technique
Stop valve mainly is made of checking-valve body, valve rod and valve plate, valve rod one end passes valve gap and is connected with handwheel, the other end is connected with the valve plate that is arranged in body cavity, rotation handwheel valve rod drive valve plate carries and moves up and down the flow of controlling the stop valve medium in the body cavity, because valve plate directly contacts with medium, on the one hand, valve plate can hinder the flow velocity of medium; On the other hand, for fields such as sewage, oil, metallurgy, medium corrodes valve plate easily under the long-time use condition, influences the working life of butterfly valve integral body; In addition, the butterfly valve upper shaft hole is under the effect of pressure medium, and medium very easily enters axis hole, thereby causes the generation of leakage situation.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of possess anti-dielectric corrosion, high sealing performance, the single action pressure bar type pinch valve of compact structure.
The utility model for achieving the above object, by the following technical solutions: a kind of single action pressure bar type pinch valve, mainly comprise handwheel, valve shaft, valve gap, valve body and flap, described handwheel and the valve shaft one end keyed jointing that passes valve gap, the valve shaft the other end is threaded with flap, it is characterized in that: described flap is slidingly connected with the valve body epicoele that is positioned at bonnet lower, described flap top shape is a circular arc camber, itself and body cavity cross section match, and are provided with the gum sleeve identical with the body cavity diameter in the vertical body cavity of valve body epicoele.
The two ends of described gum sleeve are provided with the annular snap eaves, and described annular snap eaves embeds in the end face of valve body.
Beneficial effect: the utility model is reasonable in design, and is simple in structure, and its structure is a direct current channel, no flow resistance; According to dielectric property, select the rubber bush of different rubber materials, body cavity and valve gap inner chamber and driver part partition are opened, make the valve shaft that is positioned at the rubber bush top, parts such as flap avoid the corrosion of medium, save packing seal structure, and can not produce medium and leak outside, improved the working life of valve greatly.

Fig. 2 is the sectional view of Figure 1A-A direction;
Fig. 3 is the gum sleeve structural representation.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of single action pressure bar type pinch valve mainly is made of handwheel 1, valve shaft 2, valve gap 3, valve body 4 and flap 5, handwheel and the valve shaft one end keyed jointing that passes valve gap, the valve shaft the other end is threaded with flap, flap is provided with thread bush, and the valve shaft bottom is threaded, and flap is that hollow-core construction is flap inner chamber 5-1, rotation hand wheel, valve shaft drives flap and moves up and down, and when the drive flap moved up, valve shaft one end goed deep among the flap inner chamber 5-1 gradually; When flap moved down, valve shaft withdrawed from the flap inner chamber, and the height of flap will be higher than the diameter of body cavity, can not break away from valve shaft and fall into body cavity at flap guaranteeing.Described flap is slidingly connected with the valve body epicoele 4-1 that is positioned at bonnet lower, rocks in the valve body epicoele vertically moving Shi Buhui to guarantee flap, produces the slit for a long time and causes dielectric leakage.The valve body epicoele is communicated with the body cavity 4-2 that has water intake and water outlet, described flap top shape is a circular arc camber, itself and body cavity cross section match, can be closed closely with the tube wall that guarantees gum sleeve when flap presses down, reach the effect of switch.Be provided with gum sleeve 6 in the body cavity corresponding with the body cavity coupling with flap.The diameter of gum sleeve is identical with the diameter of body cavity, guarantee that body cavity closely is connected with gum sleeve, person's medium can not flow out from the slit between valve body interior wall and the gum sleeve, in order further to guarantee the sealing of gum sleeve, the two ends of described gum sleeve are provided with annular snap eaves 6-1, the diameter of annular snap eaves is greater than the diameter of gum sleeve, and described annular snap eaves embeds the position of valve body end face adpting flange.When rotation hand wheel, valve shaft drives flap and moves down mutually, compresses gum sleeve gradually, and gum sleeve becomes concavity gradually, is the closed state of pinch valve when the tube wall phase adhesion of gum sleeve.According to the material of dielectric property selection gum sleeve, for example, if pinch valve is applied to chemical field, gum sleeve is just selected corrosion-resistant anti-aging, the rubber material that the elasticity grade is high.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from 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.
