Abstract
The utility model discloses a valve rod of a ball valve for a pipeline, which comprises a valve rod which is of a rotating body structure. The valve rod of the ball valve for the pipeline is characterized in that one end of the valve rod is provided with a boss; the diameter of the boss is greater than the diameters of other parts of the valve rod and protrudes out of the outer surface of the valve rod; and two crosscutting grooves are arranged at the matched end of the valve rod. According to the valve rod of the ball valve for the pipeline, the valve rod is provided with the boss and the boss is limited in a hole of a right valve body after being assembled, so that the valve rod can be totally prevented from flying out of the valve body and a safety accident generated due to the condition that the valve rod flies out of the valve body is avoided; the matched relation between a rectangular hole and a flat tube (which is similar with a rectangular connection end head) is adopted between the valve rod and a valve element and the valve rod and the valve element are firmly connected, so that the slippage phenomenon between the valve rod and the valve element is avoided in the rotating process of the valve rod and the valve rod can drive the valve element to smoothly rotate.
Description
Technical field
The utility model relates to appurtenances, the especially pipeline of pipeline gate valve of a kind of gas, liquid (fluid) with the valve rod of ball valve.
Background technique
In the conveyance conduit of gas, liquid (fluid); A plurality of valves all will be set to be controlled; The unlatching of controlling plumbing fixtures, close or the size of opening degree etc.; To produce corresponding action, the degree that makes pipeline open and control unlatching is as required perhaps closed, and makes gas, liquid (fluid) etc. pass through control valve.Mainly there are the problem of following several aspects in the ball valve of existing technology and valve rod thereof: 1, complex structure mostly, and the sealing configuration component of employing are more, sealing effect is undesirable, has leakage phenomenon; 2, install, dismantle inconvenient, cumbersome; 3, when hydrodynamic pressure was big, valve rod flew out from valve body, formed security incident or a potential safety hazard, can not adapt to the needs of pipeline control; 4, valve rod is not firm with being connected of spool, and there is the phenomenon of skidding in valve rod when rotating and between the spool, and the rotation of spool has some setbacks.
Summary of the invention
The utility model flies out from valve body easily to the valve rod of existing technology Ball valve of pipeline and produces the above-mentioned deficiencies such as not firm that are connected of security incident, valve rod and spool, provide a kind of and can prevent effectively that valve rod from flying out from valve body, between valve rod and the spool the firm pipeline that is connected with the valve rod of ball valve.
The technological scheme of the utility model: pipeline comprises the valve rod of rotary structure with the valve rod of ball valve, it is characterized in that: an end of said valve rod is provided with boss, and the diameter of boss protrudes from the outer surface of valve rod greater than the diameter at other positions of valve rod.
At the abutting end of valve rod, be provided with two transection slots.
Two transection slots are symmetrical set.
The pipeline of the utility model with respect to existing technology, has following characteristics with the valve rod of ball valve:
1, valve rod is provided with boss, and this boss is limited in the hole of right valve barrel after assembling, can prevent fully
Valve rod flies out from valve body, stops the security incident that valve rod flies out from valve body and produces.
2, adopt the matching relationship between rectangular opening, the flat tube (similar rectangle is connected the termination) between valve rod and the spool, it is firm to connect between the two, avoids valve rod when rotating and the skidding that exists between the spool, and valve rod can drive the smooth and easy rotation of spool.
3, simple in structure, the used component of sealing configuration are less, and sealing effect is still better.
Description of drawings
Fig. 1 is the stem structure plan view of the utility model modulating valve;
Fig. 2 is stem structure side view (a connecting end head part).
Embodiment
In Fig. 1,2, the pipeline of the utility model comprises valve rod 1 with the valve rod of ball valve, and said valve rod 1 is a rotary structure, and the one of which end is provided with boss 2, and the diameter of boss 2 protrudes from the outer surface of valve rod 1 greater than the diameter at valve rod 1 other positions; During installation, boss 2 is equipped with in the valve-rod cavity on ball valve body, by the inner chamber restriction than minor diameter above the valve-rod cavity, can up not pass through from valve-rod cavity, has just stopped valve rod 1 and from valve body, has flown out.
At the abutting end (connecting end) of valve rod 1, the abutting end that promptly is connected with ball valve body is provided with two transection slots 3, and transection slot 3 is symmetrical set; Transection slot 3 is in the termination of valve rod 1, and the direction that the edge is parallel with the medial axis of valve rod 1 goes certain-length to form apart from the back in upper and lower symmetrical position (equidistant), the crosscut vertically of medial axis.Upper and lower two symmetrically arranged transection slots 3 make the abutting end of valve rod 1; Form the structure of a similar rectangle; Can with the rectangular configuration on the valve body; Perhaps the rectangular opening of similar rectangular configuration (draw-in groove) cooperates, and it is firm that valve rod 1 and valve body are connected between the two, avoids valve rod when rotation and the skidding that exists between the spool.
The other end of valve rod 1 is connected with the actuator of ball valve and is connected, and has driven rotation by actuator.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
