Description

Ball valve for valve-controlled water meter

Technical Field

The utility model relates to the technical field of water meter manufacturing, in particular to a ball valve for a valve-controlled water meter.

Background

The ball valves have various structures, but basically have the same or different sizes, and are all valve balls with circular starting and closing parts, the opening and closing of the valve are realized by rotating a valve rod by 90 degrees, and the ball valves are used for closing, distributing, adjusting the flow and changing the flow direction of a medium on a pipeline. The valve rod middle part cover in traditional ball valve (as shown in figure 1) is equipped with two second sealing washer (5), valve rod bottom side extrudees first sealing washer (4) again with the valve rod mount pad, when actual installation, valve rod (22) and valve rod mount pad (11) cooperation require highly, the cooperation is too tight can increase the battery loss, too loose can leak water, in the later stage use, first sealing washer (4) are crowded brokenly again easily simultaneously, just so cause the phenomenon of leaking very easily, or during the ooff valve, because can have the decentraction phenomenon sometimes between valve rod (22) and valve rod mount pad (11), also cause the phenomenon of leaking very easily like this.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model aims to provide a ball valve for a valve-controlled water meter, which can further enhance the sealing effect between a valve rod and a valve rod mounting seat so as to avoid the water leakage phenomenon. In order to achieve the purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides a ball valve that valve accuse water gauge was used, includes valve body and case, be equipped with the valve rod mount pad on the valve body, the cover is equipped with the transmission system bottom plate on the valve rod mount pad, the case includes valve ball and valve rod, be equipped with the arc wall on the valve ball, be equipped with the rotatory buckle with arc wall matched with on the valve rod, valve rod mount pad bottom is equipped with the chamfer, be equipped with on the valve rod lateral wall with the binding face of the mutual inseparable laminating of chamfer, arc wall and rotatory buckle center all are equipped with toward its inside cylinder hole that extends, the card is equipped with elastic spring between the cylinder hole.

Furthermore, a plurality of water leakage grooves for conducting water outwards are formed in the bottom plate of the transmission system.

(III) advantageous effects

Compared with the prior art, the utility model has obvious advantages and beneficial effects, particularly, the chamfer at the bottom of the valve rod mounting seat is tightly attached to the attaching surface of the side wall of the valve rod through the elastic spring, so that the sealing effect between the valve rod and the valve rod mounting seat can be further enhanced, and the water leakage phenomenon is avoided.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The utility model is further described with reference to the following detailed description and accompanying drawings.

Referring to fig. 2 to 4, a ball valve for a valve-controlled water meter comprises a valve body 1 and a valve core 2, wherein a valve rod installation seat 11 is arranged on the valve body 1, a transmission system bottom plate 3 is sleeved on the valve rod installation seat 11, the valve core 2 comprises a valve ball 21 and a valve rod 22, an arc-shaped groove 23 is arranged on the valve ball 21, a rotary buckle 24 matched with the arc-shaped groove 23 is arranged on the valve rod 22, a chamfer 12 is arranged at the bottom of the valve rod installation seat 11, the chamfer 12 is a conical chamfer or an arc chamfer, an attaching surface 25 closely attached to the chamfer 12 is arranged on the side wall of the valve rod 22, a first waterproof is formed by closely attaching the attaching surface 25 to the chamfer 12, a traditional first sealing ring 4 is replaced, cylindrical holes 26 extending towards the arc-shaped groove 23 and the rotary buckle 24 are arranged at the center, that is a downward cylindrical hole 26 not penetrating through the valve ball 21 is arranged at the center of the arc-shaped groove 23, rotatory buckle 24 center is equipped with the cylinder hole 26 that up runs through rotatory buckle and set up, the card is equipped with elastic spring 27 between two cylinder holes 26, through the ascending pretightning force of elastic spring 27 increase valve rod 22, and then make chamfer 12 of 11 bottoms of valve rod mount pad closely laminate with the binding face 25 of valve rod 22 lateral wall, also can avoid having the problem of decentraction between valve rod 22 and the valve rod mount pad 11 simultaneously, can further strengthen the sealed effect between valve rod 22 and the valve rod mount pad 11, thereby avoid the phenomenon of leaking.

If a small amount of water leakage occurs, in order to prevent water from entering the transmission system of the water meter, a plurality of water leakage grooves 31 for conducting water outwards are arranged on the bottom plate 3 of the transmission system.

According to the utility model, the chamfer at the bottom of the valve rod mounting seat is tightly attached to the attaching surface of the side wall of the valve rod through the elastic spring, so that the sealing effect between the valve rod and the valve rod mounting seat can be further enhanced, and the water leakage phenomenon is avoided.
