Abstract

The utility model provides an anti-deposition angle plunger valve, including the valve body that is equipped with the slope discharge gate, the below of valve body is fixed with the stand support, the lower part and the stand support normal running fit of valve rod, the case lower part that can remove in the valve body is connected to the upper end of valve rod, the upper portion and the sealed cooperation of disk seat of case, be equipped with axial stroke chamber inside the case, the lower extreme of case is connected with the nut, the opening and the nut center intercommunication in stroke chamber, the surface of valve rod is equipped with the screw thread and is connected with the nut cooperation, and the valve rod length of threaded part is no less than to the length in stroke chamber, form the long stroke displacement structure. The utility model has the advantages of reasonable and compact structure, the valve rod only rotates, need not rectilinear movement, to the peripheral no stroke space requirement in valve position, can long stroke axial displacement when the case is stimulateeed, be enough to dodge the slope discharging channel of valve body lateral wall completely, the degree of opening is abundant, and the medium flows the blowing and almost does not have the hindrance, is difficult for appearing medium deposit crystallization in the valve body.

Description

Anti-deposition angle type plunger valve

The technical field is as follows: the utility model relates to an angle formula plunger valve, especially angle formula plunger valve that blowing was used.

Background art: in many process lines, discharge control is required and it is common to use angle plug valves as discharge valves. The valve core of the common angle plunger valve is fixedly connected with the end part of the valve rod, and the valve is opened and closed by displacement along with the linear movement of the valve rod. Because the position space that the blowing was located is narrower usually, and the specification and size of blowing valve itself is also less, and the stroke that the valve rod can rectilinear movement is limited, makes the stroke of case also shorter, and the degree of opening when leading to the valve blowing is also limited, and the back case of opening often still partly shelters from the slope discharging channel of valve body lateral wall, and the medium flows and receives the hindrance, appears the medium deposit crystallization in the valve body easily, influences the use.

The invention content is as follows: to the not enough of prior art, the utility model provides a case degree of opening is big prevents deposiing angle plunger valve.

The utility model discloses a valve body with slope discharge gate, the below of valve body is fixed with the stand support, the lower part and the stand support normal running fit of valve rod, the case lower part that can remove in the valve body is connected to the upper end of valve rod, the upper portion and the sealed cooperation of disk seat of case, be equipped with axial stroke chamber inside the case, the lower extreme of case is connected with the nut, the opening and the nut center intercommunication in stroke chamber, the surface of valve rod is equipped with the screw thread and is connected with the nut cooperation, and the valve rod length of threaded part is no less than to the length in stroke chamber, form the long stroke displacement structure of case.

The utility model has the advantages of reasonable and compact structure, the valve rod only rotates, need not rectilinear movement, to the peripheral no stroke space requirement in valve position, can long stroke axial displacement when the case is stimulateeed, be enough to dodge the slope discharging channel of valve body lateral wall completely, the degree of opening is abundant, and the medium flows the blowing and almost does not have the hindrance, is difficult for appearing medium deposit crystallization in the valve body.

The invention is further described with reference to the accompanying drawings and the detailed description.

Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.

Fig. 2 is a schematic view of the opened state of fig. 1.

The specific implementation mode is as follows: as shown in fig. 1, the valve body 1 is provided with an inclined discharge port 4, a column support 2 is fixed below the valve body 1, the lower part of the valve rod 3 is rotatably matched with the column support 2, the upper end of the valve rod 3 is connected with the lower part of a valve core 5 which can move in the valve body 1, and the upper part of the valve core 5 is in sealing fit with a valve seat 6. An axial stroke cavity 7 is arranged in the valve core 5, the lower end of the valve core 5 is connected with a nut 8, and the opening of the stroke cavity 7 is communicated with the center of the nut 8. The surface of the valve rod 3 is provided with threads and is matched and connected with the nut 8, and the length of the stroke cavity 7 is not less than that of the valve rod 3 with the threaded part, so that a valve core long stroke displacement structure is formed.

In this embodiment, the upper end of the valve body 1 is connected with the valve cover 9, and the independent valve seat 6 is arranged between the valve cover 9 and the valve body 1 and fixed. The independent valve seat 6 is convenient to produce and process, and is convenient to assemble and maintain.

When the valve is opened, the valve rod 3 can be rotated by the hand wheel 10, the nut 8 and the valve core 5 are axially moved together under the matching action of the threads, the valve rod 3 is gradually sleeved in the stroke cavity 7, and as shown in fig. 2, the valve core 5 is displaced enough to completely avoid the inclined discharge port 4 on the side wall of the valve body 1, so that the valve body is fully opened. When the valve is closed, the hand wheel 10 is reversely rotated to drive the valve core 5 to return and displace until the end part of the valve core 5 is in sealing fit with the valve seat 6.

Claims

1. The utility model provides an prevent deposiing angle formula plunger valve, is fixed with the upright post support including the valve body that is equipped with the slope discharge gate, the below of valve body, the lower part and the upright post support normal running fit of valve rod, the case lower part that can remove in the valve body is connected to the upper end of valve rod, the upper portion and the sealed cooperation of disk seat of case, characterized in that: the valve rod is characterized in that an axial stroke cavity (7) is formed in the valve core (5), a nut (8) is connected to the lower end of the valve core (5), an opening of the stroke cavity (7) is communicated with the center of the nut (8), threads are arranged on the surface of the valve rod (3) and are connected with the nut (8) in a matched mode, the length of the stroke cavity (7) is not less than that of the valve rod (3) with the threaded portion, and a valve core long stroke displacement structure is formed.
