Description
Technical Field
The utility model belongs to the technical field of diaphragm pumps, and particularly relates to a valve cone conduit device applied to a feeding and discharging valve box of a hydraulic end system of a three-cylinder single-action diaphragm pump.
Background
The existing valve cone guide pipe structure is thick and heavy, as shown in figures 3-4, the thick and heavy structure can reduce the flow passing space in the valve box body, so that materials cannot flow better.
Meanwhile, the thick and heavy structure has the problems of high production cost, inconvenience in installation, difficulty in maintenance and the like.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a novel valve cone conduit device which has simple structure and small volume and can better circulate materials in a valve box body.
In order to achieve the above purpose, the utility model adopts the following technical scheme, the utility model comprises an outer sleeve and an inner pipe, and is characterized in that: the outer diameter of the inner pipe is from top to bottom and comprises a first stage, a second stage and a third stage from large to small; the outer sleeve is matched with the first-stage outer diameter, the first-stage end face and the second-stage outer diameter; the second stage is that the outer contour extends out of the outer sleeve; the outer part of the outer sleeve is provided with a connecting flange, and connecting holes are circumferentially arranged on the connecting flange; the outer sleeve and the inner tube are locked by a locking screw.
As a preferable scheme of the present invention, the connecting flange is connected to the valve housing through a connecting bolt; the part of the inner tube, which extends out of the outer sleeve, is matched with the inner diameter of the spring; the end surface of the outer sleeve is matched with the end surface of the spring; the inner tube is connected with the valve cone in the third stage.
The utility model has the beneficial effects that: 1. the second stage structure of the inner tube can fix the spring.
2. The three-stage structure of the utility model can effectively increase the overflowing space of materials in the valve box body.
3. The utility model has simple structure and convenient processing, and has the potential of serialization and standardization popularization in similar products.

In the attached drawing, 1 is an outer sleeve, 2 is a connecting hole, 3 is an inner pipe, 4 is a locking screw, 5 is a first stage, 6 is a second stage, 7 is a connecting flange, 8 is a third stage, 9 is a valve box body, 10 is a spring, and 11 is a valve cone.
Detailed Description
The utility model comprises an outer sleeve 1 and an inner pipe 3, and is characterized in that: the outer diameter of the inner tube 3 is from top to bottom, and the inner tube comprises a first stage 5, a second stage 6 and a third stage 8 from large to small; the outer diameter of the first stage 5, the end face of the first stage 5 and the outer diameter of the second stage 6 are matched in the outer sleeve 1; the outer contour of the second stage 6 extends out of the outer sleeve 1; a connecting flange 7 is arranged outside the outer sleeve 1, and connecting holes 2 are circumferentially arranged on the connecting flange 7; the outer sleeve 1 and the inner tube 3 are locked by a locking screw 4.
As a preferable scheme of the present invention, the connecting flange 7 is connected to the valve housing 9 by a connecting bolt; the part of the inner tube 3 extending out of the outer sleeve 1 is matched with the inner diameter of the spring 10; the end surface of the outer sleeve 1 is matched with the end surface of the spring 10; the inner tube 3 is connected to a valve cone 11 in the third stage 8.
The utility model reduces the thickness of the outer sleeve 1, can be embedded into a part of the valve cover, and the outer sleeve 1 and the inner tube 3 are both provided with bosses, thereby being convenient for clamping the spring 10 and preventing the spring 10 from shifting in the horizontal direction. The utility model reduces the weight of a part of the guide pipe of the valve cone 11, has good limiting effect on the spring 10 and most importantly increases the flow passing space of slurry in the valve box. The utility model limits the position of the spring 10 in the horizontal direction well, and simultaneously increases the flow space in the valve box body 9, so that the materials can better circulate. In addition, the utility model has the advantages of simple and novel structure, convenient installation, low cost, convenient processing and field operation, and the like.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the utility model.
