AI Technical Summary
Traditional throttle valves are inconvenient to replace, have high overall replacement costs, and are difficult to maintain due to their bolt-fixing method.
The design employs a connecting post and a snap-fit device. By using the snap-fit protrusion on the connecting post to engage with the connecting hole of the valve plate, the valve plate can be quickly replaced, avoiding the need to replace the entire throttle valve.
This enables rapid replacement of valve plates, reduces maintenance costs and difficulty, and improves maintenance efficiency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of throttle valves and relates to a throttle valve, in particular to a new type of throttle valve. Background Art
[0002] The throttle valve is used to control the air flow rate of the engine. It is a controllable valve that controls the air entering the engine and determines the operating conditions of the engine. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which is then burned to do work. It is connected to the air filter at the top and the engine block at the bottom, and is called the throat of the car engine.
[0003] The traditional throttle valve adopts the method of fixing the valve plate after passing through the valve stem. It is not easy to replace the valve plate after it is damaged. The throttle valve can only be replaced as a whole and not just the valve plate. In addition, some throttle valves with replaceable valve plates are often fixed with bolts, which makes replacement inconvenient. Summary of the invention
[0004] The utility model aims to solve the above problems existing in the prior art and provides a new type of throttle valve with convenient valve plate replacement.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of throttle valve, including a valve body, a valve stem is arranged on the valve body, and is characterized in that a valve cavity is arranged in the valve body, a valve plate is arranged on the valve stem and relative to the valve cavity, a mounting groove for mounting the valve plate is provided on the valve stem, a plurality of connecting columns are provided on the valve stem and relative to the mounting groove, a plurality of connecting holes for the connecting columns to pass through are provided on the valve plate, a clamping device is provided on the connecting column, a mounting groove for mounting the clamping device is provided on the connecting column, and the clamping device consists of a clamping protrusion and a reset spring.
[0006] In the above-mentioned novel throttle valve, flanges are arranged on both sides of the valve body.
[0007] In the above-mentioned novel throttle valve, there are two connecting columns, and a limiting portion is provided on the clamping protrusion.
[0008] In the above-mentioned novel throttle valve, the flange and the valve body are integrally arranged.
[0009] Compared with the prior art, the utility model makes it faster to dismantle and repair the valve plate by cooperating the clamping device on the connecting column with the connecting hole of the valve plate, without having to replace the entire throttle valve, thereby achieving the purpose of saving costs.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the new throttle valve comprises a valve body 1, a valve stem 2 is arranged on the valve body 1, a valve cavity 3 is arranged in the valve body 1, a valve plate 4 is arranged on the valve stem 2 and relative to the valve cavity 3, a mounting groove 1 5 for mounting the valve plate 4 is provided on the valve stem 2, a plurality of connecting columns 6 are provided on the valve stem 2 and relative to the mounting groove 1 5, a plurality of connecting holes 7 for the connecting columns 6 to pass through are provided on the valve plate 4, a clamping device 8 is provided on the connecting column 6, a mounting groove 2 9 for mounting the clamping device 8 is provided on the connecting column 6, the clamping device 8 comprises a clamping protrusion 10 and a reset spring 11. When installing, first press the clamping protrusion 10 into the mounting groove 2 9 to allow the connecting column 6 to pass through the connecting hole 7. After reaching a certain position, the clamping protrusion 10 loses its restraining force and, under the action of the spring, the clamping protrusion 10 extends outward to clamp the valve plate 4, so that the installation is quick.
[0016] To be more specific, flanges 12 are provided on both sides of the valve body 1 .
[0017] To be more specific, there are two connecting posts 6 , and a limiting portion 13 is disposed on the engaging protrusion 10 .
[0018] To further elaborate, the flange 12 and the valve body 1 are integrally arranged to increase the overall strength.
[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0020] Although this article uses more terms such as valve body 1, valve stem 2, valve cavity 3, valve plate 4, mounting groove 1 5, connecting column 6, connecting hole 7, clamping device 8, mounting groove 2 9, clamping protrusion 10, return spring 11, flange 12, and limiter 13, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
