Abstract
The utility model relates to a plunger stop valve which comprises a valve body, a valve cover, a valve rod, plungers, a plunger cover, a guide sleeve, a machine frame and a hand wheel, wherein the upper part of the valve cover is connected with the machine frame and the lower part is connected with the valve body. The plungers in the valve body are fixed at both ends of the plunger cover. The upper end of the valve rod is connected with the hand wheel, and the lower end is sheathed with the plunger cover. The guide sleeve is tightly fixed on the cavity wall of the valve body and provided with through holes. The utility model overcomes the defect that the common plunger stop valve has small flow and inferior sealing properties. The utility model has the advantages of simple structure, good sealing properties, steady use, long service life and large flow, which can completely replace various plunger valves and stop valves.
Description
The utility model relates to a kind of Plunger Globe Valve.
Known Plunger Globe Valve, all constitute by valve body, valve gap, valve rod, plunger, post lid, guide sleeve, frame and handwheel etc., the top of valve gap connects frame, downside connects valve body, plunger in the valve body is fixed on post lid two ends, the upper end of valve rod connects handwheel, lower end socket post lid, and guide sleeve fastens on the chamber wall of valve body.The Plunger Globe Valve of said structure because the guide sleeve that extend in the import and export passage is longer, has therefore dwindled the flow by the fluid of valve body greatly.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby a kind of simple in structure, good seal performance, Plunger Globe Valve that flow is big are provided.
The utility model comprises valve body, valve gap, valve rod, plunger, post lid, guide sleeve, frame and handwheel, the top of valve rod connects frame, downside connects valve body, plunger in the valve body is fixed on post lid two ends, the upper end of valve rod connects handwheel, lower end socket post lid, guide sleeve is fastened on the chamber wall of valve body, and guide sleeve is provided with through hole.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, model utility comprises valve body 1, valve gap 2, valve rod 3, plunger 4, post lid 5, guide sleeve 6, frame 7 and handwheel 8, the top of valve gap 2 connects frame 7, downside connects valve body 1, and the plunger 4 in the valve body 1 is fixed on post and covers 5 two ends, and the upper end of valve rod 3 connects handwheel 8, lower end socket post lid 5, guide sleeve 6 is fastened on the chamber wall of valve body 1, and the lower end is near the seal face 10 of valve body 1 inner chamber, and guide sleeve 6 is provided with large aperture through hole 9.Down, the lower end surface of plunger 4 is close on the seal face 10 of valve body 1 inner chamber in off position.Because it is very short that the inner chamber of valve body 1 is stretched out on through hole 9 tops of guide sleeve 6, and the aperture is big again, the flow of fluid has just increased like this.Simultaneously, the lower length of guide sleeve 6 is very big, seal face 10 near valve body 1 inner chamber, like this, guide sleeve 6 inner plunger 4 neutrality has been obtained greatly improving, when the valve level or when tilt installing, plunger 4 can be eccentric, can not cause fluctuation of service and because of closing the thorough internal leakage that produces.
The utility model has a structure by above-mentioned, have good seal performance, use stable, the life-span is long, The advantage that flow is big can replace various plunger valves and stop valve fully.
