The accompanying drawings, which are incorporated in and constitute a part of this specification, are included to provide a further understanding of the utility model, and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the utility model and together with the description serve to explain the utility model and not to limit the utility model.
FIG. 1 is a schematic block diagram of the present invention according to one or more embodiments;
the device comprises a sleeve 1, a sleeve 2, a half flange 3, a top plate 4, a first lead screw 5, a nut 6, a spring 7, an elastic piece 8, a spring assembly 9, a lever 10 and a second lead screw.
Detailed Description
The first embodiment is as follows:
the embodiment provides a valve body structure of a pinch valve, as shown in fig. 1, the pinch valve comprises a valve frame, a sleeve 1 and adjusting mechanisms, wherein the sleeve 1 is arranged in the valve frame, and the sleeve 1 is circumferentially and symmetrically provided with two groups of adjusting mechanisms, namely a first adjusting mechanism and a second adjusting mechanism.
Wherein, half flanges 2 are arranged at both ends of the valve frame; the sleeve 1 is an elastic sleeve.
Furthermore, the first adjusting mechanism and the second adjusting mechanism comprise the same components and respectively comprise a lead screw, a lever 9 and a spring assembly 8, and the lead screw is arranged along the radial direction of the sleeve 1; one end of the screw rod is rotatably connected (e.g. hinged) with the center position of the lever 9, and both ends of the lever 9 are connected with the spring assembly 8. Based on the lever principle, the sleeve 1 bears the pressure of the spring assembly 8, and the reliable shutoff of the pipe clamp valve is ensured.
In the embodiment, the spring assembly 8 comprises a spring 6 and an elastic member 7, wherein one end of the spring 6 is connected with the end of the lever 9, and the other end is connected with the outer wall of the sleeve 1 through the elastic member 7. Preferably, the elastic member is made of rubber to avoid damage to the sleeve 1.
The extension and contraction direction of the spring 6 is along the radial direction of the sleeve 1. When foreign matter is present inside the casing 1, the spring 6 generates a pressing force on the casing 1 due to the cooperation of the spring 6 and the lever 9.
In this embodiment, the lengths of the lead screws of the first adjusting mechanism and the second adjusting mechanism are different, the lead screw of the first adjusting mechanism is the first lead screw 4, the lead screw of the second adjusting mechanism is the second lead screw 10, and the length of the first lead screw 4 is greater than the length of the second lead screw 10.
First lead screw 4 stretches out from roof 3 of one side of valve frame, and second lead screw 10 sets up with first lead screw 4 relatively, and the cover is equipped with nut 5 on the second lead screw 10, nut 5 is fixed with the valve frame.
The working principle of the embodiment is as follows:
as shown in fig. 1, when the valve body is in a closing process, the first lead screw 4 and the second lead screw 10 press the sleeve 1. When the sleeve 1 is at a small opening and close to closed, the spring assembly 8 presses the sleeve 1.
If a large foreign body is encountered, the spring assembly 8 at two inlets (one end of the sleeve 1 is an inlet, and the other end is an outlet) is stressed to cause the two levers 9 to act, so that the spring assembly 8 at the outlet exerts force on the sleeve 1, and the pipe clamp valve can be reliably closed by the force from the closing of the valve frame.
If meet the foreign matter of general size, two entrances spring unit 8 arouse behind the atress that two levers 9 moved, two exits spring unit 8 have the power to act on sleeve pipe 1, make the foreign matter pass through sleeve pipe 1 smoothly, can prolong sleeve pipe 1's life.
When the valve body is in a normal closing process and the valve frame is in a small opening degree, the front and rear pairs of spring assemblies 8 can enable the corresponding part of the sleeve 1 to have a large turn-off joint surface, and the pipe clamp valve can be turned off reliably.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
