Abstract

The utility model provides a handle formula ball valve, including the valve body, install in handle above the valve body, install in the handle top is used for spacingly the nut of handle vertical direction degree of freedom, set up in the handle below with the spacing dish of valve body fixed connection's angle. The utility model discloses a set up in the handle below and be used for spacingly the spacing dish of angle that the handle opened and shut reaches the purpose of brake valve handle angle scope of opening and shutting, and then solves the difficult problem of fine control angle of opening and shutting of traditional handle formula ball valve.

Description

Handle type ball valve

Technical Field

The utility model relates to a ball valve technical field especially relates to a handle formula ball valve.

Background

The ball valve, the opening and closing piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. And can also be used for regulating and controlling the fluid.

The handle type ball valve is the most common product in manual ball valves, is convenient to operate and quick to open and close, can rotate by 90 degrees from full opening to full closing, and is widely applied to various industries and common people life. However, in real life, the water pressure of actual water supply in common people is influenced by different environments and is different, the handle type ball valve is used for controlling the opening and closing angle of the ball valve in a non-fine mode, the handle is prone to being opened under the condition that the water pressure is large, the handle is opened carelessly, the water flow speed is too high, and unnecessary water resource waste is caused.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides a handle type ball valve, which aims to solve the defects in the prior art.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a handle type ball valve comprises a valve body, a handle arranged on the valve body, a nut arranged above the handle and used for limiting the degree of freedom of the handle in the vertical direction, and an angle limiting disc arranged below the handle and fixedly connected with the valve body.

Wherein, the handle controls the rotation of the internal ball body through the valve rod in the valve body; a front convex L-shaped limiting block is arranged below the front end of the handle.

A through hole for fixedly connecting with the valve body is formed in the center of the angle limiting disc; at least 6 limiting thread jacks are uniformly distributed in the left semicircular area of the angle limiting disc along the edge direction of the disc; the angle limiting disc also comprises an outer hexagon screw matched with the limiting thread jack; the outer hexagonal head of the outer hexagonal screw is in contact connection with the L-shaped limiting block of the handle.

Preferably, the height of the outer hexagonal head of the outer hexagonal screw is 3/4 the distance from the top surface of the angle limiting disc to the bottom surface of the handle.

Preferably, the angle limiting disc is fixedly connected with the valve body in a welding mode through the through hole.

Preferably, the tail end of the handle, which is far away from the L-shaped limiting block, is provided with a rubber wear-resistant layer.

Has the advantages that:

the utility model discloses a set up in the handle below and be used for spacingly the spacing dish of angle that the handle opened and shut reaches the purpose of brake valve handle angle range of opening and shutting, and then solves the problem that traditional handle formula ball valve is difficult for slight control angle of opening and shutting, promptly under the great condition of water pressure, the handle is opened the angle carelessly and is leaded to the too fast flow of rivers velocity of flow too big, causes the extravagant problem of unnecessary water resource. The utility model discloses simple structure is novel, and the practicality is strong, is fit for promoting on a large scale.

Reference numerals: the valve comprises a valve body 1, a handle 2, a nut 3, an angle limiting disc 4, an L-shaped limiting block 5, a through hole 6, a limiting thread jack 7, an outer hexagon screw 8, an outer hexagon head 9 and a rubber wear-resistant layer 10.

Detailed Description

In order to further understand and appreciate the structural features and advantages of the present invention, preferred embodiments and the accompanying drawings are described in detail as follows:

a handle type ball valve is shown in figures 1-5 and comprises a valve body 1, a handle 2 arranged on the valve body 1, a nut 3 arranged above the handle 2 and used for limiting the degree of freedom of the handle 2 in the vertical direction, and an angle limiting disc 4 arranged below the handle 2 and fixedly connected with the valve body 1;

wherein, the handle 2 controls the rotation of the internal ball body through the valve rod in the valve body 1; a forward convex L-shaped limiting block 5 is arranged below the front end of the handle 2;

a through hole 6 for fixedly connecting with the valve body 1 is formed in the center of the angle limiting disc 4; at least 6 limiting thread jacks 7 are uniformly distributed in the left semicircular area of the angle limiting disc 4 along the edge direction of the disc; the angle limiting disc 4 further comprises an outer hexagon screw 8 matched with the limiting thread jack 7; the outer hexagonal head 9 of the outer hexagonal screw 8 is contactably connected with the L-shaped limiting block 5 of the handle 2. Further, the outer hexagon screw is inserted into the limiting thread insertion holes in the angle limiting discs at different positions, so that the rotation angle of the L-shaped limiting block at the front end of the handle is limited, and the effect of controlling the angle opening and closing angle range of the handle is achieved.

Further, in the present embodiment, the height of the outer hexagonal head 9 of the outer hexagonal screw 8 is 3/4 of the distance from the top surface of the angle-limiting disk 4 to the bottom surface of the handle 2.

Further, in the present embodiment, the angle limiting disc 4 is fixedly connected to the valve body 1 through the through hole 6 in a welding manner.

Further, in this embodiment, a rubber wear-resistant layer 10 is disposed at a tail end of the handle 2 away from the L-shaped limiting block 5.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
