Cover on the water inlet, the side of the closure is hinged with the inwall for crossing water cavity.Closure is hinged with water inlet
Position be arranged on the inwall of water cavity, it is to avoid impurities accumulation in water in water inlet so that the impurity solved be stuck in it is close
Capping is with water inlet hinged place the problem of block check valve.
More preferably to realize the utility model, it may further be：Rotating shaft, the rotating shaft are installed with the side of the closure
It is hinged with the inwall for crossing water cavity.
More preferably to realize the utility model, it may further be：Close to the rotating shaft two ends on the inwall for crossing water cavity
Position offer rotating shaft storage tank, the end of the rotating shaft is located in the rotating shaft storage tank, the rotating shaft with it is described
Rotating shaft storage tank is rotatably assorted.This mode, realizes closure with crossing being hinged for water cavity inwall, easy processing simple in construction, production
Cost is low.
More preferably to realize the utility model, it may further be：The inwall of the water inlet extends to be formed to the water cavity excessively
The boss of annular, the closure is covered on the boss.
More preferably to realize the utility model, it may further be：Sealing ring is installed with the boss, in the closure
On be installed with sealing gasket, when the closure cover on the boss when, the sealing gasket is fitted with the sealing ring.
More preferably to realize the utility model, it may further be：On the water inlet of the valve body and the outer wall of delivery port
Annular slot is offered, annular slot is easy to install hydraulic pipeline in the check valve both sides.
More preferably to realize the utility model, it may further be：Torsion spring is equiped with the middle part of the rotating shaft, the torsion spring is used
Rotated all the time to the boss direction around the rotating shaft in making the closure.
The beneficial effects of the utility model：By improving closure and its articulated position, it is applied to the utility model defeated
Send the water that water quality is poor, it is to avoid strip impurity blocks the phenomenon of check valve in water, it is ensured that check valve normal work；Existed by rotating shaft
Rotated in rotating shaft storage tank, realize closure with crossing the articulated manner of water cavity inwall, simple in construction, valve body is easily integrally formed,
Cost is low；Sealing gasket and sealing ring are set between closure and boss, make the fluid stopping effect of check valve more preferable.

Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4：A kind of agricultural irrigation check valve, includes the valve body of cylinder type, is in the middle part of the valve body
Water cavity is crossed, the diameter for crossing water cavity is more than the water inlet diameter of the valve body, and closure is provided with the valve body, described close
Capping is covered on the water inlet, and the side of the closure is hinged with the inwall for crossing water cavity.By closure and water inlet
The position being hinged was arranged on the inwall of water cavity, it is to avoid the impurities accumulation in water is in water inlet, so that the impurity card solved
The problem of closure and water inlet hinged place block check valve；
It is such with crossing being hinged for water cavity inwall to realize closure, is installed with rotating shaft in the side of the closure, institute
Rotating shaft is stated to be hinged with the inwall for crossing water cavity；Opened up close to the position at the rotating shaft two ends on the inwall for crossing water cavity
There is rotating shaft storage tank, the end of the rotating shaft is located in the rotating shaft storage tank, the rotating shaft turns with the rotating shaft storage tank
It is dynamic to coordinate.This mode, realizes closure with crossing being hinged for water cavity inwall, easy processing simple in construction, production cost is low.Described
