Abstract
The utility model relates to an automatic compensated cock valve, belonging to the field of valves. The plug valve comprises a valve body, a plug cock and an end cover, wherein the plug cock is installed inside the valve body; a sealing gasket is arranged at the part where the platform shoulder plane of the plug cock is contacted with the valve body; the cock valve is characterized in that the plug cock is cylindrically shaped; corresponding to the plug cock, the end cover is fixed at the bottom of the valve body through a bolt; a pressure spring is installed between the end cover and the plug cock; and spring bases are arranged at the two ends of the pressure spring respectively. With the adoption of the cock valve which is simple in structure, when the sealing gasket is abraded, the plug cock and the sealing gasket are always kept in a tight contact state under the action of the pressure spring, so that the leakage of conveyed liquid at the plug cock part is prevented effectively; by arranging spring bases at the two ends of the pressure spring respectively, the abrasion of the pressure spring on the bottom of the plug cock and the end cover is reduced, and the service life of the cock valve is prolonged.
Description
Technical field
The utility model relates to a kind of automatic compensation stopcock, belongs to valve field.
Background technique
At present, stopcock has characteristics simple to operate and easy to maintenance through being commonly used on the liquid conducting pipes.The sealing of existing stopcock is between valve body or gland and cock, soft filler to be housed, and with its compacting, reduces the gap between valve body and the cock through gland, stops the leakage of carrying liquid.Though this kind sealing means effect is better, service time is of a specified duration, and its slit can be strengthened gradually, like untimely adjustment and repairing, will cause leakage, pollutes working environment.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of automatic compensation stopcock is provided, and it is simple in structure, can prevent to carry the leakage of liquid in cock place, long service life effectively.
The described automatic compensation stopcock of the utility model; Comprise valve body, cock and end cap, cock is installed in the valve body, and cock shoulder facial planes and valve body contacting point are provided with gasket seal; It is characterized in that: cock is cylindrical; The corresponding cock of end cap is equipped with pressure spring through being bolted to the valve body bottom between end cap and cock, the pressure spring two ends are respectively arranged with spring seat.
At the pressure spring two ends spring seat is set respectively, can prolongs the working life of pressure spring.
Wherein, be provided with seal ring between said end cap and the cock.
During work, if gasket seal has wearing and tearing, under the effect of pressure spring, make cock and gasket seal remain on tight state of contact always, prevented the leakage of cock place effectively, it is simple in structure, long service life.
Compared with prior art, the utlity model has following beneficial effect:
Through the utility model, it is simple in structure, when gasket seal has wearing and tearing, under the effect of pressure spring, makes cock and gasket seal remain on tight state of contact always, can prevent to carry the leakage of liquid in cock place effectively; Owing to be respectively arranged with spring seat at the pressure spring two ends, reduced the wearing and tearing of pressure spring to cock bottom and end cap, prolonged working life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, gasket seal 2, cock 3, valve body 4, end cap 5, pressure spring 6, spring seat 7, seal ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in Figure 1, compensate stopcock automatically, comprise valve body 3, cock 2 and end cap 4; Cock 2 is installed in the valve body 3, and cock 2 shoulder facial planes and valve body 3 contacting points are provided with gasket seal 1, it is characterized in that: cock 2 is for cylindrical; End cap 4 corresponding cocks 2 are through being bolted to valve body 3 bottoms; Be provided with seal ring 7 between end cap 4 and the valve body 3, between end cap 4 and cock 2, pressure spring 5 be installed, pressure spring 5 two ends are respectively arranged with spring seat 6.
During work,, under the effect of pressure spring 5, make cock 2 and gasket seal 1 remain on tight state of contact always, prevented the leakage at cock 2 places effectively if gasket seal 1 has wearing and tearing.
