Abstract

The invention provides a pressure-balancing valve for an irrigation system, which is characterized in that: a valve body for connecting a water inlet/outlet pipe is provided with an interceptor plate and an overflow hole; a valve core arranged in the valve body consists of a cylinder body, a piston and a limit spring; a cone of an end part of the piston fits with the overflow hole; and water inlet channels are arranged among the piston, the cylinder body and the valve body. The pressure-balancing valve has simple structure, can be conveniently connected to each branch pipe of the irrigation system, and automatically balance water inlet pressure to keep the flow in an irrigation pipe consistent.

Description

A kind of irrigation system equilibrated valve
Technical field
The present invention relates to a kind of irrigation system equilibrated valve, relate in particular to applying pressure adjusting on a kind of small-sized irrigation pipeline, belong to irrigation installation accessory technical field.
Background technique
The current voltage adjusting device cost of production that is applied in agriculture micro irrigation technology field at present is high, is installing and using middle complicated operation, largely limit the popularization and application of micro irrigation technology.The claimant once disclosed two kinds of voltage adjusting devices, and 1, irrigate and use the float type automatic voltage regulator: the patent No. 03257227.1, the problem that comes out in the use are the buoyancy returns that relies on float, when current change, and the action instability.2, irrigate and use the piston type automatic voltage regulator, patent No. 03123545.X, this pressure-regulating device is parallelly connected with the current loop, or piston and current loop intersect vertically, complex structure, and after loop and the component increase, be easy to generate fault.Be exactly that this pressure governor all relatively is applicable to large-scale pipeline in addition, can not satisfy the especially usage requirement of booth precision agriculture of small-sized irrigation system.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, be adapted at the equilibrated valve installed on each irrigation system line branching, to solve the irrigation skewness weighing apparatus problem that causes because of the hydraulic pressure instability.
Technological scheme of the present invention provides a kind of irrigation system equilibrated valve; Its characteristic comprises: in the valve body of connection turnover water pipe intercepter plate and flowing hole are set; The spool that is provided with in the valve body is by cylinder body; Piston and limit spring are formed, and the conical surface of pistons end and flowing hole coincide, and are provided with intake tunnel between piston/cylinder and the valve body.
Described irrigation system equilibrated valve, said spool is for being fixed on stepped shaft cylinder body in the valve body, and corresponding piston also is a stepped shaft.
Described irrigation system equilibrated valve, said piston is provided with seal ring.
Described irrigation system equilibrated valve, described intake tunnel are to be looped around piston/cylinder through hole or annular aperture on every side.
Described irrigation system equilibrated valve, said valve body setting and turnover water pipe connection interface are screw thread or bayonet socket.
Described irrigation system equilibrated valve is provided with the self-locking locking ring that the anti-decylization annular ratchet in 1-5 road and internal diameter of suit are provided with annular ratchet on the external diameter of the interface that said valve body is connected with turnover water pipe.
Described irrigation system equilibrated valve, the annular ratchet tooth top external diameter on the described said valve body interface is greater than the annular of the internal diameter on locking ring ratchet tooth top internal diameter.
Described irrigation system equilibrated valve, the annular ratchet tooth top external diameter on the described said valve body interface increases successively, or the internal diameter of self-locking locking ring annular ratchet tooth top internal diameter dwindles successively.
The beneficial effect that the present invention produced is, can be advantageously connected in each branch line of irrigation system, and the autobalance intake pressure is consistent the flow that gets in the irrigation pipeline.

Among the figure: 1, screw thread 2, valve body 3, intake tunnel 4, seal ring 5, limit spring 6, piston 7, sealing 8, Rectifier plate 9, flowing hole 10, cylinder body 11, interface 12, locking ring 13, locking ring annular ratchet 14, thin walled tube 15, interface annular ratchet
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Irrigation system equilibrated valve shown in Fig. 1-3; About screw thread or the bayonet socket that connects turnover water pipe is set; Intercepter plate 8 and flowing hole 9 are set in the valve body 2; Spool of the present invention is cylinder body, piston 6 and the limit spring 5 that in valve body, is provided with, and the conical surface of pistons end and flowing hole coincide, and are provided with intake tunnel 3 between piston/cylinder and the valve body.
Said spool is for being fixed on stepped shaft cylinder body in the valve body, and corresponding piston 6 also is a stepped shaft.When current get into equilibrium valve, piston 6 is formed pressure, hydraulic pressure is hour; Piston keeps motionless under limit spring 5 supports, when hydraulic pressure increased gradually, current increased the pressure that piston forms gradually; After surpassing the spring yield pressure; Promote piston and move to the right, the piston microcephaly conical surface is moved to the flowing hole 9 of Rectifier plate 8 gradually, until inserting flowing hole.
In hydraulic pressure increase process, the piston microcephaly conical surface when the flowing hole of Rectifier plate moves, dwindles through the flow channel cross section of cavity flow to flowing hole gradually gradually, causes the pressure of equilibrium valve right side water outlet to keep balance.Piston is provided with seal ring 4,7.
The present invention provide intake tunnel 3 technological schemes are through hole or the annular aperture that are looped around around the piston/cylinder.
In order to solve valve body and the connectivity problem of irrigating thin walled hose; Fig. 4 has provided the elongation technology scheme of valve body of the present invention and a kind of Placement of inlet and outlet pipe; Anticreep annular ratchet 15 is set on the external diameter of valve body interface 11, and internal diameter of suit has the self-locking locking ring 12 of annular ratchet 13 in advance.After being socketed in thin walled hose 14 on the valve body interface 11, to reverse interface pulling locking ring 12, annular ratchet is about to thin-wall pipes and is locked on the valve body.
Wherein, the 15 tooth top external diameters of the annular ratchet on the valve body interface 11 are greater than the annular of the internal diameter on the locking ring 12 ratchet 13 tooth top internal diameters.
Annular ratchet 15 tooth top external diameters on the valve body interface can be designed to equate or increase successively from left to right.Perhaps the annular ratchet tooth top internal diameter on self-locking locking ring 12 internal diameters is designed to equate or reduce successively.
Foregoing description only proposes as a kind of enforceable technological scheme of irrigation system equilibrated valve of the present invention, not as the single restrictive condition to its technological scheme itself.
