Novel manual ball valve

Abstract

The utility model provides a novel manual ball valve. The novel manual ball valve comprises a ball valve body and a switch locking piece. The ball valve body comprises a center portion located in the middle and pipe connecting portions symmetrically arranged on the left side and the right side of the center portion, a valve element is arranged in the center portion, a valve rod connected with the valve element in a matched mode is arranged at the upper end of the center portion, and a handle is installed at the upper end of the valve rod. The switch locking piece comprises a locking head, a base and supporting pieces, wherein the locking head and the base are vertically arranged, and the supporting pieces are bilaterally symmetrically arranged. The ball valve has the beneficial effects that when the ball valve is completely opened or closed, the strip-shaped insertion hole and the limiting insertion hole of the locking head correspond to the position of the locking handle, and therefore the situation that the ball valve is touched by mistake or the switch is not in place is effectively prevented.

Description

Technical Field

[0001] The invention relates to the technical field of ball valves, and in particular to a novel manual ball valve. Background Art

[0002] A manual ball valve is a valve whose main feature is that the valve is opened and closed by rotating the ball. Its working principle is to open or close the valve by rotating the valve core (i.e. the ball). When the ball rotates 90 degrees around the center line of the valve body, the valve is opened or closed. The manual ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Specifically, it can be used to cut off or connect the medium, and can also be used for fluid regulation and control.

[0003] At present, the existing manual ball valve lacks the function of locking the handle, that is, the valve core position during use, and there is a possibility of accidental touch or failure to switch in place. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a novel manual ball valve.

[0005] The specific plan is as follows:

[0006] A novel manual ball valve, characterized in that it comprises a ball valve body and a switch locking piece; the ball valve body comprises a central part located in the middle and connecting pipe parts symmetrically arranged on the left and right sides of the central part, a valve core is arranged in the central part, a valve stem matched with the valve core is arranged at the upper end, and a handle is installed at the upper end of the valve stem; the switch locking piece comprises a locking head and a base arranged up and down, and a supporting piece symmetrically arranged on the left and right, the locking head is a door-shaped structure, composed of a longitudinal rod and two vertical rods symmetrically arranged front and back, and the middle part of the vertical rod is provided with a handle matching the handle in the vertical direction The vertical rod is provided with a strip-shaped socket, and the lower end of the strip-shaped socket is connected to the bottom surface of the vertical rod. The bottom of the left and right sides of the longitudinal rod are symmetrically provided with limit assemblies, and the limit assemblies include two limit blocks symmetrically arranged front and back, and a limit socket matched with the handle is left between the two limit blocks. The base is located at the bottom of the center part, including a rectangular frame and a vertical rod. There are four vertical rods, which are respectively arranged at the top of the four vertex corners of the rectangular frame. The spacing between the two vertical rods on the front side and the spacing between the two vertical rods on the rear side are both matched with the vertical rod. The support is placed on the connecting pipe part and fixedly connected to the base.

[0007] Furthermore, a flange is provided at the end of the connecting pipe portion.

[0008] Furthermore, the support member includes an arc-shaped plate and a cross bar, both ends of the arc-shaped plate are connected to the same side with a cross bar, one end of the cross bar is fixedly connected to the end of the arc-shaped plate, and the other end is fixedly connected to the upper end of the vertical bar of the base through bolts.

[0009] The beneficial effect of the present invention is that when the ball valve is fully opened or closed, the bar-shaped socket and the limit socket of the locking head can correspond to the position of the locking handle respectively, thereby effectively preventing accidental touch or the switch from being in place.

[0014] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0015] As shown in the figure, the present invention provides a new type of manual ball valve, including a ball valve body 1 and a switch locking piece; the ball valve body 1 includes a central part located in the middle and connecting pipe parts symmetrically arranged on the left and right sides of the central part, a valve core is arranged in the central part, a valve stem 2 matched with the valve core is arranged at the upper end, and a handle 3 is installed at the upper end of the valve stem 2; the switch locking piece includes a locking head 4 and a base 5 arranged up and down, and a support piece 6 symmetrically arranged on the left and right, the locking head 4 is a door-shaped structure, composed of a longitudinal rod and two vertical rods symmetrically arranged front and back, and the middle part of the vertical rod is provided with a handle in the vertical direction 3, and the lower end of the strip jack 7 is connected to the bottom of the vertical rod. The bottom of the left and right sides of the longitudinal rod are symmetrically provided with limit assemblies, and the limit assembly includes two limit blocks 8 symmetrically arranged front and back, and a limit jack 9 adapted to the handle 3 is left between the two limit blocks 8. The base 5 is located at the bottom of the center part, including a rectangular frame and vertical rods. There are four vertical rods, which are respectively arranged at the top of the four vertex corners of the rectangular frame. The spacing between the two vertical rods on the front side and the spacing between the two vertical rods on the rear side are both adapted to the vertical rods. The support member 6 is placed on the connecting pipe portion and fixedly connected to the base 5.

[0016] In this embodiment, a flange is provided at the end of the connecting pipe portion.

[0017] In this embodiment, the support member 6 includes an arc-shaped plate and a crossbar. The two ends of the arc-shaped plate are connected to the same side with a crossbar. One end of the crossbar is fixedly connected to the end of the arc-shaped plate, and the other end is fixedly connected to the upper end of the vertical pole of the base 5 by bolts. During installation, the two support members are placed on the left and right connecting pipes respectively, and then the base is placed at the bottom of the center part, and then the four crossbars are fixedly connected to the corresponding vertical poles by four bolts. During use, when the ball valve is fully opened or closed, the handle is in the horizontal or vertical position respectively. At this time, the locking head is inserted into the base, and its limit socket and strip socket can fix the position of the handle respectively, thereby effectively preventing accidental touch or the switch from being in place.
