Description

Technical Field

[0001] The utility model relates to the technical field of short ball valves, and specifically relates to a structure of a short ball valve. Background Technique

[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can be used for the regulation and control of fluids. The hard-sealed V-type ball valve has a very strong shearing force between its V-type ball core and the metal valve seat surfacing with hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, shunt, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. The ball valve is divided into pneumatic ball valve, electric ball valve, and manual ball valve according to the driving method. The ball valve is widely used in industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal engineering, and steel.

[0003] However, the existing ball valves do not have the function of filtering water flow during use, and the impurities in the water flow are likely to cause blockage of the pipeline after long-term use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structure of a short ball valve to solve the problems put forward in the above background technique.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A structure of a short ball valve includes a valve stem, a valve body, a ball, and a filtering component arranged inside the ball. The filtering component includes a filter plate, a filter screen, a connecting plate, fastening bolts, and a reinforcement mechanism. The filter plate is movably arranged on the inner wall of the ball. The filter screen is fixedly arranged on the inner wall of the filter plate. Two symmetrically distributed connecting plates are fixedly connected to both the upper and lower sides of the filter plate. The connecting plate is internally threaded with the fastening bolts, and the reinforcement mechanism is arranged at the lower end of the fastening bolts.

[0006] In a preferred embodiment: A receiving groove corresponding to the fastening bolts is arranged on the wall of the ball. An opening is arranged at the upper end of the receiving groove, and the opening is opened on the outer surface of the ball, and the diameter of the opening is lower than the diameter of the receiving groove.

[0007] In a preferred embodiment: The reinforcement mechanism includes a connecting block, a clamping block, and a receiving cavity. The lower end of the fastening bolt is fixedly connected with the connecting block. A receiving cavity is arranged on the inner wall of the connecting block, and two symmetrically distributed clamping blocks are slidably connected in the receiving cavity.

[0008] In a preferred embodiment: One end of the two clamping blocks slides outside the connecting block, and the wall of the end of the clamping block far from the receiving cavity is an arc-shaped wall.

[0009] In a preferred embodiment: The clamping block slides between the end walls close to each other in the receiving cavity, and a return spring is fixedly connected therebetween.

[0010] In a preferred embodiment: The sphere is rotatably arranged in the valve body. A valve rod sleeve is provided on the valve body. The valve rod is rotatably arranged in the valve rod sleeve. The lower end of the valve rod is connected to the sphere. There are also a support ring and a flange on the wall of the valve body. One end of the support ring is connected to the inner wall of the flange. A valve seat matching therewith is provided on the inner wall of the support ring. A plurality of rivets are equidistantly distributed on the wall of the flange.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0012] Through the arrangement of the filter plate, filter screen, connecting plate and fastening bolts, the present utility model rotates the valve rod to drive the sphere to rotate, so that the ball valve is opened. After the ball valve is opened, the liquid to be transported can be filtered through the filter screen, thereby avoiding subsequent blockage of the water outlet. After the filter screen works for a period of time, the fastening bolt can be rotated to remove the fastening bolt, so that the fastening bolt is separated from the connecting plate. Then the filter plate can be removed from the sphere, and then the filter screen can be replaced and maintained. It is convenient for the filtration work of the water flow when the ball valve is in use, avoiding blockage of the water outlet caused by impurities in the water flow and affecting the transportation work of the water flow. And with the setting of the reinforcement mechanism, it is also convenient for the disassembly and assembly of the filter screen, facilitating the regular replacement and maintenance of the filter screen, which is beneficial to the use of the device.
