Abstract
The utility model provides a counter-clipped type multiposition silencing non-return valve. The utility model is composed of a valve body, a valve shuttle, a hole cover, a press plate, a rubber pad and a valve core shuttle, wherein, the upper opening part of the valve body is connected with the hole cover. The valve shuttle is movably matched with an inner cavity of the valve body. A convex pipe of the bottom surface of the valve shuttle is fixedly connected with the rubber pad by the pressing plate. The opening part of a shaft core hole of the valve shuttle is movably matched with the valve core shuttle. The edge of a top opening of the valve shuttle is fixedly connected with a baffle sheet by screws, and the baffle sheet is used for positioning a core shuttle. The utility model has the advantages of novel structure, tight closing, small operation resistance, low noise, firmness, durability and convenient operation, and is suitable for various liquid transfer pipelines with pressure. The utility model is especially matched with pumps, and the utility model is a novel non-return valve.
Description
The utility model relates to a kind of valve, and especially a kind of and the supporting installation of water pump are impacted the safety check of pump reversing in order to prevent when the termination of pumping pressure water stream in the pipeline.
In known technology, existing safety check is mainly by valve body, connection seat, core shuttle with help and close spring and form.Because existing safety check system adopts to help and closes spring action spool shuttle and valve body connection and touch to touch for rigid plane and close structure, make when closed water hammer pressure impact the spool shuttle and touch that to close impact noise big, hard plane is touched to close and is also easily caused bad sealing close, especially help that to close spring more fragile, and influence the use of valve, cause and use inconvenience.
The purpose of the utility model provides a kind of novel structure, closed tight, low, the valve shuttle flexible operation of noise, non-return valve easy to use.
For achieving the above object, the technical solution adopted in the utility model is: adopt the bowl-shape valve body that is shaped on base aperture, valve body upper oral part load port lid, in body cavity, install the valve shuttle movingly, along limit formula rubber cushion, the bottom outlet seat of the rubber cushion of valve shuttle and the valve body company of touching is movingly realized the closed of check valve body base aperture or is opened by the fixedly connected ball of pressing plate in the bottom surface of valve shuttle; And on the valve shuttle, be shaped on axis through-hole, the axle center hole upper oral part is installed movingly by the shuttle plate and is connected the valve core spindle of being formed with clamping plate folder even cushion rubber and by nut, the cushion rubber of heart shuttle and valve shuttle the axle center hole company of touching are movingly realized the closed of valve shuttle axle center hole or are opened, also the top of valve shuttle mouth along on by the screw intentionally location washer of shuttle that is connected, the damping check valve of the wafer type multidigit that is combined into.During use, damping check valve of the present utility model is fitted on the pipeline of pump discharge,, after pressure water stream promotes heart shuttle earlier and moves the axle center hole sealing of its cushion rubber with the valve shuttle in the pipe, promotes the valve shuttle again and move its rubber cushion the valve base mouth is sealed when the pump stopping time.Because the axle center hole of the cushion rubber of heart shuttle and valve shuttle touches and is linked as flexibility and touches; the rubber cushion of valve shuttle and valve block hole also touch for circle face flexibility; institute's surface of contact is a damping, buffering ring; having formed the two-stage flexibility again touches and closes; the moment kinetic energy of water hammer pressure in the pipe is converted into the work done of two stage compression buffering, thereby reduces and subdued the water hammer pressure energy, increased the damping function of closure of check ring; weaken the vibrations that cause of water hammer pressure of moment in the pipeline and hit sound, realized the purpose of protection pump and pipeline.
Because the utility model has adopted the two-stage valve shuttle to consist of the two-stage flexibility and touched structure, can subdue the water hammer pressure in the pipeline effectively, reduce the closed noise of valve, protection pump and pipeline.Therefore, the utility model is than existing check valve structure novelty, closed tight, valve shuttle flexible operation, and resistance is little, noise is low, and is sturdy and durable, easy to use.It is applicable to various have in the pressure infuser pipeline especially match with pump, be a kind of novel damping check valve.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model embodiment concrete structure.
Fig. 2 is the plan view of valve shuttle (3) among Fig. 1.
Fig. 3 is the sectional view of Fig. 2 along the A-A line.
