Abstract
The utility model provides a valve sealing structure applied to the field of agricultural irrigation, which comprises an eccentric hemispherical valve plate, an O-shaped ring, a hard sealing gasket, a soft sealing gasket, a check ring, a valve body, a spring and an end cover, wherein the valve sealing structure adopts two sealing modes of soft sealing (rubber) +hard sealing (polytetrafluoroethylene), so that absolute sealing of the valve structure under various pressure conditions is realized. The two sealing gaskets are pushed by the spring to be tightly matched with the valve plate, so that the valve leakage caused by the loss of the spring force due to the aging of the sealing gaskets can be effectively improved.
Description
Technical Field
The utility model relates to the field of intelligent agricultural irrigation, in particular to a sealing structure of an intelligent agricultural irrigation valve.
Background
With the continuous progress of agricultural technology, intelligent irrigation technology is widely applied to modern agriculture. The valve is indispensable in agricultural intelligent irrigation system, especially in some remote areas with larger farmland area, the valve quantity in farmland is more, at present, a round sealing ring hard sealing mode is adopted between a well-known three-way ball valve body and a ball body, the sealing mode is easy to leak, good sealing effect cannot be ensured, the irrigation valve is exposed outdoors for a long time, and is influenced by factors such as climate, illumination and the like, the sealing gasket of the valve is easy to age, elasticity is lost, water quality for irrigation is poor, most of impurities such as soil and broken stone particles are contained, and abrasion of the valve sealing piece is extremely easy to cause.
Disclosure of Invention
The utility model provides a valve sealing structure applied to the field of agricultural irrigation, which adopts a hard sealing and soft sealing dual sealing mode to ensure the sealing effect of a valve.
In order to achieve the above object, the technical scheme of the present utility model is as follows:
intelligent agricultural irrigation valve seal structure contains eccentric hemisphere valve plate, O type circle, hard sealing pad, soft sealing pad, retaining ring, valve body, spring, end cover, characterized by:
the eccentric hemispherical valve plate is fixed on the valve body through a valve shaft;
the hard sealing gasket is sleeved with the O-shaped ring;
the soft gasket may be fitted to the hard gasket;
the check ring and the soft sealing gasket are provided with corresponding screw holes;
the retainer ring, the hard sealing gasket and the soft sealing gasket are fixed into a sealing assembly and then are arranged in the valve body;
the spring is arranged between the sealing assembly and the end cover;
the end cover is in threaded connection with the valve body.
The utility model has the beneficial effects that:
(1) The intelligent agricultural irrigation valve sealing structure adopts two sealing modes of soft sealing (rubber) +hard sealing (polytetrafluoroethylene), and realizes absolute sealing of the valve structure under various pressure conditions.
(2) According to the intelligent agricultural irrigation valve sealing structure, the two sealing gaskets are tightly matched with the valve plate by means of the elastic force of the spring, so that valve leakage caused by the fact that the elastic force of the sealing gaskets is lost due to elastic aging can be effectively improved.
(3) The intelligent agricultural irrigation valve sealing structure adopts a hemispherical valve plate structure, and compared with a traditional ball valve, the intelligent agricultural irrigation valve sealing structure can effectively reduce the contact area between the valve and a sealing gasket when the valve is opened, thereby reducing the driving torque.
(4) The intelligent agricultural irrigation valve sealing structure has the advantages that the valve plate is of a hollow structure, and compared with a traditional solid sphere structure, the intelligent agricultural irrigation valve sealing structure can reduce the material weight of the valve sphere and reduce the driving torque of the valve.
Drawings
FIG. 1 is a schematic diagram of the sealing structure of the intelligent agricultural irrigation valve.
Detailed Description
The technical scheme of the utility model is further described in detail below with reference to the detailed description and the accompanying drawings.
As shown in fig. 1: the intelligent agricultural irrigation valve sealing structure comprises an eccentric hemispherical valve plate (1), an O-shaped ring (2), a hard sealing pad (3), a soft sealing pad (4), a check ring (5), a valve body (7), a spring (6) and an end cover (8).
The eccentric hemispherical valve plate is fixed on the valve body through the valve shaft, and the eccentric hemispherical valve plate structure is adopted, so that the contact area between the valve and the sealing gasket when the valve is opened is effectively reduced, and the torque is reduced.
The O-shaped ring is sleeved on the hard sealing gasket, so that the sealing performance between the hard sealing gasket and the valve body is guaranteed.
The soft sealing gasket can be assembled into the hard sealing gasket, the check ring and the soft sealing gasket are provided with corresponding screw holes, the check ring, the hard sealing gasket and the soft sealing gasket are fixed into a sealing assembly and then are arranged in the valve body, the soft sealing gasket adopts two sealing modes of soft sealing (rubber) +hard sealing (polytetrafluoroethylene), the hard sealing is a main sealing structure, most of water pressure leakage can be effectively isolated, the soft sealing is an auxiliary sealing mode, and the leakage of tiny water pressure can be solved, so that the absolute sealing of the valve structure under various pressure conditions is realized. The method comprises the steps of carrying out a first treatment on the surface of the
The spring is arranged between the sealing assembly and the end cover, and the two sealing gaskets are pushed to be tightly matched with the valve plate by means of the elastic force of the spring, so that valve leakage caused by the loss of the elastic force due to the elastic aging of the sealing gaskets can be effectively improved;
the end cover is in threaded connection with the valve body.
According to the structure, 5 prototypes are manufactured, and the sealing requirements can be met through the sealing performance test under various water pressures.
