Abstract
The utility model relates to a slow-closing check valve, comprising a valve body, a valve cover, a valve seat, a guide rod, a buffering bowl, an end cover, a sealing pad, a spring, and a buffering pad. The end cover is covered on an opening on one side of the valve body. One end of the guide rod is fixed on the end cover, and the other end is extended into a buffering bowl which is fixed on the valve seat through a support frame. The valve seat is sheathed and is fixed in the valve body. The middle part of the guide rod is installed and fixed with the valve cover. One side of the valve cover is fixed with the sealing pad. The guide rod is sheathed with the spring and the buffering pad. The utility model has obvious advantages that the water hammer noise is not had, the impact among the components can be avoided; the sealing property is great; the service life is long; the installation is not limited by the angle; the flow is not reduced in opening.
Description
The utility model relates to engineering element or the parts in the mechanical engineering, is a kind of novel valve body.
Fluid flow safety check in the existing machinery engineering, mostly adopt Lift check valve, structure is directly to be stamped a valve gap on the valve seat mouth, for solving the guiding problem, be equipped with directional post on the valve gap, be sleeved in the fixed guide hole on top, be equipped with a guiding conical ring that is inserted in the valve seat under the valve gap, when closing valve, utilize valve gap deadweight and current back-suction that valve gap is covered valve seat, water hammer when having produced that our common water valve cuts out like this, the sound is big, and poor sealing performance, leakage phenomenon is arranged, valve gap and valve seat bump are serious, the parts loss is fast, and incrustation scale attaches after use a period of time, moves ineffective, can not normally open and close, and existing general safety check is when opening, and flow dwindles, and general valve body is installed and will be subjected to angle limits.
The purpose of the utility model aims to provide a kind of water hammer noise, the bump of avoiding valve gap and valve seat, good seal performance when eliminating the liquid valve and closing, is not subjected to incrustation scale to influence, install the slow closed check damper that is not subjected to angle limits, long service life.
Fig. 1 is the utility model structure longitudinal sectional view.
Technical solution of the present utility model is: this slow closed check damper is by valve body (1), valve gap (8), valve seat (12), guide post (5), buffering bowl (13), end cap (3), sealing gasket (9), spring (7), cushion pad (6) consists of, end cap (3) covers on a side opening of valve body (1), guide post (5) one ends are fixedly on the end cap (3), the other end is inserted in the buffering bowl (13), buffering bowl (13) is fixed on the valve seat (12) by bracing frame, valve seat (12) suit is fixed in the valve body (1), guide post (5) middle part installs and fixes valve gap (8), valve gap (8) one sides install and fix sealing gasket (9), valve Around guide post (5) spring (7) and cushion pad (6) are installed between lid (8) and the end cap (3).
Provide embodiment of the present utility model below in conjunction with accompanying drawing: as shown in Figure 1, this slow closed check damper includes valve body (1), valve seat (12), end cap (3), valve gap (8), guide rod (5), buffering bowl (13), sealing gasket (9), spring (7), cushion pad (6), valve body (1) has water intake (14), water outlet (15) and end cap (3) opening, end cap (3) covers on valve body (1), end cap (3) also makes it to be tightly connected by O-ring seals, guide rod (5) one ends are fixedlyed connected with end cap (3) by nut (4), cushion pad (6) is installed around inboard guide rod (5) one ends of end cap (3), guide rod (5) the other end stretches in the buffering bowl (13), and has certain clearance with buffering bowl (a 13) inwall, buffering bowl (13) is connected and fixed by several supporting frames (16) and valve seat (12), valve seat (12) is fixed on valve body (1) inwall, valve seat (12) upper end port but also packing ring (10) is installed, guide rod (5) middle part is fixedly connected with valve gap (8), a side of valve gap (8) is connected and installed with sealing gasket (9), valve gap (8) can cover valve seat (12) and seal with it by sealing gasket (9) and packing ring (10), guide rod (5) outer race between valve gap (8) and end cap (3) is equipped with spring (7), this slow closed check damper is when closing valve, because former full of liquid in the buffering bowl (13), guide rod (5) is driven by valve gap (8) and stretches into buffering bowl (13) when interior, need to discharge ponding or hydrops in the buffering bowl (13), again because the guide rod end is not too big with buffering bowl inwall gap, thereby ponding or hydrops absorb the impact energy that valve gap transmits by guide rod, play the purpose of buffering, the cushion pad of end cap inboard then is when valve gap is opened, and avoids valve gap directly to clash into end cap.
Advantage: effectively eliminated the bump that produces De Shui Chung noise when closing valve, avoided valve gap and valve seat and end cap, good seal performance, not affected by incrustation scale, long service life, install and be not subjected to angle limits, do not reduce flow during unlatching, reasonable in design ingenious, manufacturing is simple, cost is low, and serviceability is good.
