Abstract
The utility model discloses a horizontal free ball core type check valve including a valve body; a valve cap on the valve body; a valve plate is mounted at the lower part in the valve body and arranged in the horizontal direction; a round mouth is formed on the valve plate; a stop lever is mounted above the valve plate; a spherical valve core is arranged in the valve body; the spherical valve core is arranged in a space surrounded by the valve body, the valve plat and the stop lever; a water inlet is arranged at the lower end of the valve body; and a water outlet is arranged at the upper end of the valve body. The check valve has a valve core in a free ball shape, and the valve core is not connected with the valve body, so that the check valve can not have a failure due to rustiness and water scale at the joint with the valve body, and the watertight effect can be ensured. Besides, the structure is simple and not easy to damage, and the production cost is low. When in use, the maintenance is convenient even in case of failures, the check valve is not required to be demounted from a water net, and only the valve cap is required to be opened.
Description
Technical field
The utility model belongs to valve, relates in particular to the free ball core type safety check of a kind of horizontal type.
Background technique
Safety check on the market has two kinds now, and a kind of is the safety check of round pie spool, and the deficiency of this kind safety check is the joint of valve body, because mechanical friction is arranged, and very easily malfunctioning under the situation that rust and incrustation scale are arranged.Another kind is a spring wafering type valve core safety check, and deficiency is under spring action, and current will be by needing higher hydraulic pressure, and when water pipe hydraulic pressure was low, water just can't pass through, and the structure relative complex, and the cost height is fragile.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, reliable operation, the free ball core type safety check of horizontal type easy to maintenance.
For achieving the above object, the utility model adopts following technological scheme: the free ball core type safety check of a kind of horizontal type, comprise valve body, valve gap is housed on the valve body, valve plate is housed in the valve body, valve plate is positioned at substantially horizontal, circular port is arranged on the valve plate, pin also is housed in the valve body, also has a spherical valve core in the valve body, spherical valve core is positioned at the space that is surrounded by valve body, valve plate and pin.
The proportion of spherical valve core is slightly larger than water.
The proportion of spherical valve core is 1.05～1.2g/cm
3
This safety check, spool are spherical free style, with valve body without any being connected, be unlikely to because of get rusty with the valve body joint and incrustation scale malfunctioning, the circular port of spool and valve plate can grind under the effect of current voluntarily, guarantees stagnant water effect.And simple in structure, not fragile, cost of production is low.In use,, also be convenient to safeguard, do not need to unload, as long as open valve gap from the network of rivers even go wrong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
The free ball core type safety check of horizontal type as shown in Figure 1 and Figure 2, comprise valve body 5, valve gap 4 is housed on the valve body 5, valve plate 6 is housed in the valve body, valve plate is positioned at substantially horizontal, and circular port is arranged on the valve plate, and pin 3 also is housed in the valve body, also have a spherical valve core 2 in the valve body, spherical valve core 2 is positioned at the space that is surrounded by valve body 5, valve plate 6 and pin 3.
The proportion of spherical valve core should be decided on its purposes, promptly is a bit larger tham the proportion of liquid in the pipeline.In the time of on being used in water pipe, the proportion of spherical valve core is larger than water, is preferably 1.05～1.2g/cm
3
When current by behind the valve inleting water mouth 7, spherical valve core 2 is washed open by current, pin 3 can prevent that spherical valve core 2 from stopping the current proper flow, current pass through, and flow out from water outlet 1.When water when water outlet 1 flows backwards, spherical valve core 2 is blocked the circular port on the valve plate under the effect of current, play the effect that refluxes that stops.
The proportion of ball core is slightly larger than water, both can prevent that hydraulic pressure is low and is not easy to back down spherical valve core, spherical valve core is fallen stop backflow.
Spool of the present utility model is spherical free style, with valve body without any being connected, be unlikely to because of get rusty with the valve body joint and incrustation scale malfunctioning, the circular port of spool and valve plate can grind under the effect of current voluntarily, guarantees stagnant water effect.
The utility model is simple in structure, and not fragile, cost of production is low.In use,, also be convenient to safeguard, do not need to unload, as long as open valve gap from the network of rivers even go wrong.
