Abstract
Description
Technical Field
[0001] The utility model relates to the field of sight glass check valves, in particular to a sight glass check valve. Background Art
[0002] A sight glass check valve is a valve whose opening and closing part is a circular disc and which relies on its own weight and control pressure to produce movement to block the flow of fluid. The disc movement modes are divided into lifting type and swing type.
[0003] When the current fluid flows in the sight glass check valve, the flow of the fluid in the valve body cannot be observed from the outside, so there is room for improvement. Utility Model Content
[0004] The utility model aims to provide a sight glass check valve to solve the problems raised in the above background technology, and the utility model has the advantage of being able to observe the flow of fluid in the valve body.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sight glass check valve, comprising a valve body, a ball is arranged in the valve body, a spring is arranged on one side of the ball, a limit plate is arranged in the valve body, one end of the spring is on one side of the ball, and the other end of the spring is on one side of the limit plate, and the valve body is equipped with a glass sight glass on the side of the ball.
[0006] By adopting the above technical solution, the medium flows in from the side of the ball away from the spring, pressing the ball so that the ball moves toward the side of the spring and then squeezes the spring. When no fluid flows in, the ball returns to its original position under the action of the spring and then blocks the valve body. During this process, the fluid flow in the valve body can be observed through a glass sight glass.
[0007] Preferably, the valve body is a fluorine-lined valve body.
[0008] As a further solution of the utility model: the valve body comprises an upper valve body and a lower valve body, a bolt is passed through the upper valve body and the lower valve body, and nuts are threadedly connected at both ends of the bolt.
[0009] By adopting the above technical solution, the upper valve body and the lower valve body are connected together by bolts, and then the nuts are rotated to fix the bolts.
[0010] As a further solution of the utility model: one side of the nut is integrally connected with a reinforcing rod located on the side of the bolt.
[0011] By adopting the above technical solution, the rotating nut drives the reinforcing rod to move, and the reinforcing rod is located in the circumference of the bolt, thereby enhancing the stability of the bolt.
[0012] As a further solution of the utility model: a convex block is integrally connected to the valve body on one side of the glass sight glass, and a mating plate is installed in the valve body on one side of the glass sight glass.
[0013] By adopting the above technical solution, the convex block plays a role of limiting, so that the glass sight glass can only be on one side of the convex block. The mating plate fills the gap between the bolt and the glass sight glass, squeezes one side of the glass sight glass, and increases stability. It should be noted that the mating plate is set to be narrow and only blocks the linear field of view on one side of the glass sight glass.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The medium flows in from the side of the sphere away from the spring, presses the sphere so that the sphere moves towards the side of the spring and then squeezes the spring. When there is no fluid flowing in, the sphere returns to its original position under the action of the spring and then blocks the valve body. In this process, the fluid flow situation in the valve body can be observed through the glass sight glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] In the embodiment of the present utility model,
[0020] A sight check valve, as Figure 1 shown, includes a valve body. A sphere 2 is arranged in the valve body. A spring 3 is arranged on one side of the sphere 2. A limiting plate 4 is arranged in the valve body. One end of the spring 3 is on one side of the sphere 2, and the other end of the spring 3 is on one side of the limiting plate 4. The valve body is provided with a glass sight glass 5 on the side of the sphere 2.
[0021] The valve body is selected as a fluorine-lined valve body 6.
[0022] The valve body includes an upper valve body 7 and a lower valve body 8. A bolt 9 is passed through between the upper valve body 7 and the lower valve body 8, and nuts 10 are threadedly connected to both ends of the bolt 9.
[0023] One side of the nut 10 is integrally connected with a reinforcing rod 11 on the side of the bolt 9.
[0024] The valve body is integrally connected with a convex block 12 on one side of the glass sight glass 5, and a mating plate 1 is installed in the valve body on one side of the glass sight glass 5.
[0025] Working principle:
[0026] The medium flows in from the side of the sphere 2 away from the spring 3, presses the sphere 2 so that the sphere 2 moves towards the side of the spring 3 and then compresses the spring 3. When there is no fluid flowing in, the sphere 2 returns to its original position under the action of the spring 3 and then blocks the valve body. In this process, the fluid flow situation in the valve body can be observed through the glass sight glass 5.
[0027] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
