Along with social development, not only easy for installation and firm and durable of research, and the valve of economic, energy-conservation and environmental protection, seem particularly important.In prior art, in the middle of upper-mounting type ball valve, because valve seat is longer, and the installation of spring is all with spring seat, in the situation that having pressure, can cause the stability of spring, spring seat bad, is difficult to reach the balance of valve seat and spheroid.
Model utility content
For above-mentioned defect of the prior art and problem, the utility model embodiment's object is to provide a kind of novel upper-mounting type valve body structure of better reliability, thereby increases work efficiency.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of novel upper-mounting type valve body structure, by valve body, spring seat, spring, valve seat, spheroid, bonnet, valve rod, Gland, extension pipe bar and pneumatic actuator form, it is characterized in that, sphere installation is on valve body inner bottom part medial axis, valve seat is located in valve body, the upper and lower outside two ends of spheroid, spring seat matches with valve seat, and in the groove of spring fitting substantially horizontal in spring seat, also be provided with drilled tunnel in groove front, valve rod is arranged on spheroid top, bonnet is positioned at valve body top, around valve rod, and be provided with Gland between bonnet and valve rod, extension pipe bar entangles valve rod top, and be connected with Gland by nut bolt, pneumatic actuator is positioned at extension pipe bar top.
As technique scheme preferably, the cross section of described valve seat, spring seat is all L-shaped, and the right angle knuckle of the cross section of spring seat and valve seat fastens mutually, its concrete Placement is, be positioned at the valve seat at outside two ends under spheroid and be arranged on spring seat top, and the drilled tunnel along continuous straight runs of spring seat is arranged on towards a side of valve body, the front of groove; Be positioned at the valve seat at outside two ends on spheroid and be arranged on spring seat below, and the drilled tunnel along continuous straight runs of spring seat is arranged on towards a side of valve body, the front of groove.
The novel upper-mounting type valve body structure that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: simple in structure, drilled tunnel easy to use, to arrange on spring seat, while having guaranteed air pressure by spring seat, gas interacts, and cancels out each other, and has guaranteed the stable of valve seat and spheroid.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
