Quick ball valve of card pressure

Technical Field

The utility model belongs to the technical field of valve bodies, and particularly relates to a clamping and pressing quick-connection ball valve.

The ball valve is a valve, the valve core of the ball valve is spherical, the valve rod is utilized to drive the ball valve to rotate around the axis during use, the ball valve becomes a main valve along with the development of science, and the utilization rate of the ball valve is increased year by year due to the characteristics of wear resistance and light switching of the ball valve. In order to prevent water leakage, materials such as lead oil, wire hemp or polytetrafluoroethylene raw material tape and the like are required to be filled in the thread, the situation that the filling materials are not in place and water leakage occurs is easy to occur, the installation efficiency is low, and the labor cost is high. The quick-connect ball valve shown in CN113503373a, where the pipe body is connected by a threaded sleeve, is also capable of ensuring tightness, but also makes the installation complicated, and makes quick installation inconvenient. The screw thread is connected with the internal screw thread. The internal thread connection is used for processing the end part of the valve body into threads, the external thread fittings are needed for connection, the manufacturing cost of the threaded connection is high, two external thread fittings are needed for installation, the installation speed is low, and the labor cost is high. The auxiliary materials are more needed, and lead oil, wire hemp or polytetrafluoroethylene raw material tape filling is needed for installing a ball valve to an external thread accessory, so that the ball valve is in a sealing state. The probability of water leakage occurs when the filling is not in place is easy to occur. The threaded connection ball valve needs to have the requirement on the space of the installation place, the installation ball valve needs to be installed on the ball valve firstly by two external threads, the space angle distance on the installation pipeline is not well controlled, water leakage is easy to occur when the installation is not in place, and the water leakage needs to be detached and reinstalled, so that manual repeated operation is caused.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

the snap-in ball valve, as shown in FIG. 1, comprises

A valve body 20 having a tube connecting portion 22, the tube connecting portion 22 having an annular outer flange 221,

the outer wall of the connecting end of the pipe body 10 is provided with a connecting sealing section 11, and the connecting end of the pipe body 10 is sleeved on the pipe body connecting part 22;

wherein the outer annular flange 221 is embedded inside the connecting seal segment 11, and a sealing element 13 is arranged between the inner wall of the outer annular flange 221 and the outer wall of the connecting seal segment 11. By arranging the sealing element 13, the sealing of the gap can be better realized, and the sealing element 13 has an annular structure.

As shown in fig. 2, the valve body 20 includes a valve spool 21, and a valve cavity of the valve spool 21 may communicate with at least two pipe body connection portions 22. The valve cavity is internally provided with a through ball core body, and when the ball core body rotates and is in an open state, the ball core body is communicated with at least two pipe body connecting parts 22.

The pipe body connecting part 22 can be extruded and deformed, and the pipe body connecting part 22 is pressed inwards to press and connect the pipe body connecting part 22 with the pipe body 10.

One such way is that the valve cavity is in communication with two tube connecting portions 22, or the valve cavity is in communication with four tube connecting portions 22, and of course, as the number of tube connecting portions 22 changes, the number of channels in the ball core changes. For example, in the case of the two-way valve of fig. 2, the ball core has a through passage, and in the case of the three-way valve, and three openings are needed, the passage of the ball core needs only three openings and can be simultaneously realized with the pipe body connecting portion 22.

With the example shown in fig. 2, the valve cavity of the valve cartridge 21 communicates with two pipe body connecting portions 22, the ball cartridge having a liquid through hole; when the ball core rotates, two ends of the liquid through hole are respectively communicated with the two pipe body connecting parts 22.

In the use process, the ball core body is connected with the control handle, and the ball core body is driven to rotate through the control handle.

As shown in fig. 2, the pipe body connecting portion 22 has annular concave portions 222 on both sides of the annular outer flange 221, and the pipe body 10 has connecting convex portions 12 on both sides of the connecting seal segment 11.

Similarly, the outer annular flange 221 projects outwardly, and the inner annular recess 222 is concave with respect to the outer annular flange 221, but the inner annular recess 222 itself maintains the original tubular form. When the pipe body 10 is sleeved on the valve body 20, firstly, the end head of the pipe body 10 is directly sleeved on one end of the connecting part 22, and then, the pipe body 10 and the connecting part 22 are simultaneously and inwards subjected to annular extrusion from the outermost periphery, so that the pipe body 10 and the connecting part are tightly connected, and concave-convex structures arranged on the pipe body 10 and the connecting part 22 are mutually nested to realize limit as shown in fig. 3. The stainless steel clamping quick-connection ball valve is directly connected with the pipeline, so that the traditional two external thread fittings are omitted, and the cost and the use space are saved; the stainless steel clamping and pressing quick-connection ball valve is used, an external threaded connector is not needed, and lead oil, wire hemp or polytetrafluoroethylene raw material tape filling of an external threaded fitting is avoided. Saving the cost of auxiliary materials. The probability of water leakage is reduced; the stainless steel clamping and pressing quick-connection ball valve has low requirement on installation space, saves installation time, is more than 10 times faster than the traditional threaded connection installation time, does not need to install an external threaded connector on a pipeline, has no limitation on angles and positions during installation, and can be freely adjusted by 360 degrees.
