Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and particularly relates to a new type of ball valve. Background Art

[0002] As a pipeline opening and closing valve, the ball valve has been widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, water conservancy, electric power, gas pipelines, plumbing, and domestic drinking water, and occupies a crucial position in the national economy.

[0003] Currently, there are still some deficiencies in the existing ball valves. Firstly, the existing ball valves lack a filtering device. When the ball valve works, impurities in the water body will directly contact the ball in the ball valve, increasing the wear degree of the ball and even causing the ball to get stuck, thereby reducing the stability of the ball valve during use. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of ball valve with reasonable design, simple structure and filtering function for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of ball valve includes a valve body and a valve stem. A valve ball is arranged in the valve body, and the lower end of the valve stem is connected to the valve ball and controls its rotation. The valve body has a water inlet pipe for water inlet and a water outlet pipe for water outlet. Its characteristic lies in that a filtering component is arranged at the position of the valve body relative to the water inlet pipe. The filtering component is composed of a filtering ring and a filter net. A fixing part is arranged at the position of the valve body relative to the water inlet pipe. A positioning part for positioning the filtering component is arranged on the fixing part. An installation groove for installing the positioning part is opened in the fixing part. A connecting spring is arranged between the positioning part and the fixing part. Two positioning rods for positioning the filtering ring are arranged on the valve body. A first positioning hole for the positioning rod to pass through is opened on the filtering ring. A second positioning hole matched with the positioning part is opened at the side end of the filtering ring. Under the action of the connecting spring, the positioning part slides in the installation groove so that the positioning part is matched with the second positioning hole to fix the filtering component.

[0006] In the above-mentioned new type of ball valve, one end of the positioning part extends out of the fixing part and is connected with a pull plate, and the other end of the positioning part extends out of the installation groove and is matched with the second positioning hole on the side wall of the filtering ring.

[0007] In the above-mentioned new type of ball valve, an external pipeline is connected to the valve body at the position relative to the water inlet pipe, and the external pipeline abuts against the filtering ring to further position the filtering component.

[0008] In the above-mentioned new type of ball valve, two positioning parts are provided and are respectively arranged at the left and right ends of the fixing part.

[0009] Compared with the prior art, in the new type of ball valve, a detachable filter assembly is provided at the water inlet of the valve body to filter the water entering the valve body, avoiding abrasion of the ball caused by impurities in the water and affecting the service life of the valve body.

[0014] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0015] As Figure 1 、 Figure 2 、 Figure 3 shown, the new type of ball valve includes a valve body 1 and a valve stem 2. A valve ball 3 is arranged in the valve body 1, and the lower end of the valve stem 2 is connected to the valve ball 3 and controls its rotation. The valve body 1 has a water inlet pipe for water inlet and a water outlet pipe for water outlet. It is characterized in that a filter assembly 4 is arranged on the valve body 1 at a position relative to the water inlet pipe. The filter assembly 4 is composed of a filter ring 5 and a filter net 6. A fixing part 7 is arranged on the valve body 1 at a position relative to the water inlet pipe. A positioning part 8 for positioning the filter assembly 4 is arranged on the fixing part 7. An installation groove for installing the positioning part 8 is formed in the fixing part 7. A connecting spring 9 is arranged between the positioning part 8 and the fixing part 7. Two positioning rods 12 for positioning the filter ring 5 are arranged on the valve body 1. A first positioning hole for the positioning rod 12 to pass through is formed in the filter ring 5. A second positioning hole matching with the positioning part 8 is formed in the side end of the filter ring 5. Under the action of the connecting spring 9, the positioning part 8 slides in the installation groove so that the positioning part 8 matches with the second positioning hole to fix the filter assembly 4.

[0016] Specifically, one end of the positioning member 8 extends out of the fixing portion 7 and is connected with a pull plate 10, and the other end of the positioning member 8 extends out of the installation groove and is engaged with the second positioning hole on the side wall of the filter ring 5.

[0017] Specifically, when installing the filter assembly 4, first engage the first positioning hole on the filter ring 5 with the positioning rod 12 on the valve body 1, pull the pull plate 10 to make the end of the positioning member 8 extending out of the installation groove retract into the installation groove. When one end of the filter ring 5 abuts against the valve body 1, release the pull plate 10, and the connecting spring 9 rebounds. One end of the positioning member 8 extends into the second positioning hole of the filter ring 5 to fix the filter assembly 4 at the water inlet of the valve body 1. After positioning, the external pipeline 11 is then connected to the valve body 1, and one end of the external pipeline 11 abuts against the end face of the filter ring 5.

[0018] Specifically, an external pipeline 11 is connected to the valve body 1 relative to the water inlet pipeline, and the external pipeline 11 abuts against the filter ring 5 to further position the filter assembly 4.

[0019] Specifically, two positioning members are provided and are respectively arranged at the left and right ends of the fixing portion 7.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although terms such as valve body 1, valve stem 2, valve ball 3, filter assembly 4, filter ring 5, filter net 6, fixing portion 7, positioning member 8, connecting spring 9, pull plate 10, external pipeline 11, positioning rod 12, etc. are used more in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
