Abstract
The utility model relates to a pressing cover. The pressing cover is installed on a valve. An inner ring groove is formed in the inner wall of the pressing cover, a seal ring is arranged inside the inner ring groove, and the pressing cover is pressed tightly through matching of the inner ring groove and the seal ring and is fixed. Due to the facts that the inner ring groove is formed in the inner wall of the pressing cover and provided with the seal ring for pressing in a matched mode, tightness is improved, the pressing cover is fixed and can not be dismantled easily, and protecting performance is improved.
Description
Technical field
The utility model relates to valve field, relates in particular to a kind of gland.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Valve is the important control device that promotes the device development of modern transportation water, gas, stream material, the valve of Shi Yonging in the market, and one owing to gland is not set, after long-time, because the accumulation of dust is unfavorable for opening of valve, open difficulty when causing maintenance.
The two, the valve that has has gland, but gland is loosening easily in the long-time back of using, and is easy to take off poor sealing performance.
The model utility content
In view of this, be necessary to provide a kind of good seal performance, be not easy to take off, have the gland of good protective action.
The utility model is achieved in that a kind of gland, and described gland is installed on the valve, and described gland inwall is provided with inner groove.
Further, be provided with seal ring in the described inner groove, gland compressed by inner groove and cooperating of seal ring, and it is fixed, and was difficult for taking off, and had improved sealing simultaneously.
Further, the upper end closed of described gland, lower ending opening.
The advantage of the gland that the utility model provides is: by inner groove being set, and seal ring is set on inner groove cooperates and compresses, improve sealing at the gland inwall, and fixing not quick detachable, improve protective value.
Description of drawings
Fig. 1 is an existing valve mechanism schematic representation described in the background technique;
Fig. 2 is the assembling schematic representation of the utility model gland;
Fig. 3 is the sectional view of the utility model gland.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, Fig. 1 is an existing valve mechanism schematic representation described in the background technique.
Existing valve comprises valve body 1, valve gap 2, valve plate 3, valve rod 4, valve plate seal ring 5, gland 6, handwheel 7 and valve seals 8.The inside of valve body 1 is provided with bigger cavity, and there is unlimited opening at two ends, is convenient to entering and flowing out of fluid like this.Valve gap 2 is installed in the top of valve body 1, and valve gap 2 inside are provided with certain cavity, and the cavity of this cavity and valve body 1 inside mates mutually.Be provided with valve seals 8 between valve gap 2 and the valve body 1,, utilize the locking nut (not shown) that the three tightly is locked together in case fluid is revealed.The oral area of valve gap 2 upper ends is less, and the oral area inboard is provided with internal thread.
Bigger cavity central position at valve body 1 is equipped with valve plate 3, between the both sides of valve plate 3 and the valve body 1 valve plate seal ring 5 is installed, and valve plate 3 is flat tabular, and its size is bigger slightly than the cavity in the valve body 1, just in time can stop fluid to flow in valve body 1.Valve rod 4 is installed directly over the valve plate 3, and valve rod 4 is provided with outside thread.Valve rod 4 passes the oral area of valve gap 2 upper ends, and the internal thread of outside thread on the valve rod 4 and valve gap 2 oral areas is meshing with each other.
Be provided with gland 6 in valve gap 2 upper ends, gland 6 neutral positions are provided with center hole, gland 6 and valve gap 2 screw-threaded couplings.Gland 6 upper ends are provided with handwheel 7, and handwheel 7 centers are provided with elongated center-pole 7a, and center-pole 7a passes the center hole of gland 6, are connected and fixed with valve rod 4.
When rotation hand wheel 7, center-pole 7a drives valve rod 4 rotations, and under valve gap 2 oral area screw-thread fit, valve rod 4 rotations also move up and down, and drive moving up and down of valve plate 3 by moving up and down of valve rod 4 like this, finally realize the open and close of valve.
See also Fig. 2 and Fig. 3, wherein Fig. 2 is the assembling schematic representation of the utility model gland; Fig. 3 is the sectional view of the utility model gland.
Gland described in the utility model is to improve on existing valve mechanism basis, and it improves component and comprises: gland 6 '.
Described gland 6 ' inwall is provided with inner groove 61 ', is provided with seal ring 9 in the described inner groove 61 ', and gland 6 ' compressed by inner groove 61 ' and cooperating of seal ring 9, it is fixed, be difficult for taking off, improved sealing simultaneously, the upper end closed of described gland 6 ', lower ending opening.
By inner groove 61 ' being set, and seal ring 9 is set on inner groove 61 ' cooperates and compress at gland 6 ' inwall, fixing not quick detachable, improve protective value.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
