Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the implementations of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Example 1

Referring to fig. 1-3, a valve with an angle gauge comprises a valve body 1, an opening and closing member 2 arranged in the valve body 1, a valve rod 3 extending into the valve body 1 and connected with the opening and closing member 2, a handle 4 arranged at the end part of the valve rod 3 exposed outside the valve body 1, and an angle gauge 5 fixed between the valve body 1 and the handle 4 and fixed on the outer surface of the valve body 1 through fixing rods 6, wherein the number of the fixing rods 6 is 2-4 and extends to one side of the handle 4, the valve rod 3 is provided with pluggable bolts 7, and the bolts 7 are matched with the fixing rods 6 to limit the rotation of the valve rod 3.

In the actual use process, when the center position of the valve is aligned with the zero line of the angle gauge 5, the opening and closing part 2 completely blocks the flow of the fluid in the valve, and when the valve rotates for a certain angle, the opening and closing part 2 gradually increases the cross-sectional area of the fluid flow channel, so that the flow rate of the fluid in the valve body 1 is increased;

and be superior to the angle square 5 that sets up between valve body 1 and handle 4, and then be convenient for the operator to judge handle 4 pivoted angle, and then be convenient for control valve body 1 internal fluid's flow, simultaneously, consider probably taking place the operator and probably can twist handle 4, and then lead to the unable accurate control's of flow condition, consequently the dead lever 6 with fixed angle square 5 is extension, and through the cooperation of dead lever 6 and the bolt 7 of transversely passing valve rod 3, and then make valve rod 3 rotate to angle square 5's the biggest measured value or minimum measured value after, unable continuation rotates, thereby guarantee the accuracy to flow control.

In this embodiment, the valve with the angle gauge is a ball valve, and the opening and closing member 2 is a sphere with a through hole in the middle; of course, the valve is not excessively limited in the form of the valve, the valve is mainly suitable for a valve capable of adjusting fluid flow, and when in actual use, other valves such as a butterfly valve and the like which can control the opening and closing device to block or conduct the valve body 1 through rotating the handle 4 can be selected, but note that the control of the opening and closing device can be completed through rotating the handle 4 for a plurality of circles by part of the valves, and the scheme of the application is not suitable for the valve with the rotating cycle number within a circle.

Meanwhile, the valve in the embodiment is a ball valve, so that the ball valve is characterized in that the valve body 1 can realize the transition from the minimum flow passage to the maximum flow passage of the fluid by rotating the opening and closing device by 90 degrees, so that the corresponding maximum measured value of the angle gauge 5 is 90 degrees, the number of the fixing rods 6 is 4, on one hand, the number of the fixing rods 6 is four, the angle gauge 5 is better fixed, the stability of the angle gauge 5 is improved, on the other hand, the graph formed after the connecting lines of the 4 fixing rods 6 in sequence is square, and the bolt 7 can be limited to rotate only between the two fixing rods 6 by the cooperation of the fixing rods 6 and the bolt 7, and then the maximum rotating angle of the valve rod 3 can be limited to only 90 degrees, so that the inaccuracy of flow control caused by over-screwing of the handle 4 is prevented.

For further accurate control of the flow, the end of the handle 4 is provided with a pointer 8, and when the opening and closing member 2 blocks the flow of fluid in the valve, the pointer 8 points to the minimum measured value of the angle gauge 5; of course, in actual use, the operator can change the state of the pointer 8 to the maximum value of the angle ruler 5 when the opening and closing member 2 blocks the three-dimensional flow in the valve, but the direction of the handle 4 which needs to be rotated is easier to judge in consideration of following the rule that the larger the angle of the pointer 8 is increased, so the design is made.

As a conventional technology in the field, an anti-skid piece is arranged on the outer surface of the handle, and the anti-skid piece is an anti-skid convex point arranged on the outer surface of the handle.

As a further preferable aspect of this embodiment, the indexing value of the angle gauge is set to 1 ° in consideration of the fact that the flow rate in the valve body is greatly changed by rotating the shutter by a small angle.

To sum up, the valve with angle chi in this application can be through the accurate angle of knowing the handle pivoted of angle chi, and then help operating personnel judge, simultaneously, still can restrict the rotation of valve rod through the cooperation between the fixed column that is used for fixed angle chi and the bolt that passes the valve rod, and then reduced operating personnel and crossed the condition emergence that leads to flow control inaccurate with the handle because of the mistake to, this application simple structure, the operation of being convenient for.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
