Description
Technical field
The present invention relates to valve field, especially a kind of axial flow pressure maintaining valve of relying on oneself.
Background technique
The Main Function of pressure maintaining valve is suitably to reduce pressure, voltage stabilizing and current stabilization, particularly water source under high pressure conditions, can also keep stablizing hydraulic pressure and flow, avoid moment to produce very big detonation pressure simultaneously, cause product impaired.
Traditional pressure maintaining valve is because reasons in structure, the pressure that cannot respond downstream changes, under high pressure conditions, there is flow defect on the low side in its water source, in the time that source pressure raises gradually, its water flowing sectional area can produce reduction sharp to be changed, but not reduction changes lenitively, thereby affect the stability that medium circulates.
Summary of the invention
The technical problem to be solved in the present invention is: for provide a kind of simple in structure, good airproof performance, can automatic voltage regulation, ensure that medium supplies the stable axial flow pressure maintaining valve of relying on oneself.
The technical solution adopted for the present invention to solve the technical problems is: a kind of axial flow pressure maintaining valve of relying on oneself, comprise valve body, air guide sleeve, flap, guide rod, spring and cylinder, described air guide sleeve is fixed on valve body one end, air guide sleeve liquid entering hole is communicated with body cavity, described flap is arranged on body cavity and matches with air guide sleeve, described guide rod is fixedly connected with flap, described cylinder is fixedly connected with guide rod, cylinder moves left and right by guide rod control flap so that body cavity is opened or closed, and between described valve body and guide rod, is provided with spring.
In a preferred embodiment of the present invention, the interior one-body molded fitting seat that has of described valve body, in described fitting seat, offer piston cylinder, described cylinder, guide rod are arranged in piston cylinder, between guide rod and fitting seat, be connected by spring, fitting seat is convenient to cylinder and guide rod is arranged in valve body, can not affect the sealing of valve.
In a preferred embodiment of the present invention, between described fitting seat and guide rod, be provided with O type circle, improve sealability.
In a preferred embodiment of the present invention, described body cavity is oval, is convenient to medium and passes through body cavity.
The invention has the beneficial effects as follows: axial flow of the present invention is relied on oneself pressure maintaining valve by the cooperation of cylinder, guide rod and flap, pressure that can automatic regulating valve door upstream and downstream, thus ensure the stable supplying of medium.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the rely on oneself structural representation of pressure maintaining valve of axial flow of the present invention;
In figure: 1. spring, 2. guide rod, 3. valve body, 4. air guide sleeve, 5. flap, 6.O type circle, 7. cylinder, 8. fitting seat.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of axial flow pressure maintaining valve of relying on oneself, comprise valve body 3, air guide sleeve 4, flap 5, guide rod 2, spring 1 and cylinder 7, described air guide sleeve 4 is fixed on valve body 3 one end, air guide sleeve 4 liquid entering holes are communicated with valve body 3 inner chambers, described flap 5 is arranged on valve body 3 inner chambers and matches with air guide sleeve 4, described guide rod 2 is fixedly connected with flap 5, described cylinder 7 is fixedly connected with guide rod 2, cylinder 7 controls by guide rod 2 that flap 5 moves left and right so that valve body 3 inner chambers are opened or close, and between described valve body 3 and guide rod 2, is provided with spring 1.
The interior one-body molded fitting seat 8 that has of described valve body 3, in described fitting seat 8, offer piston cylinder, described cylinder 7, guide rod 2 are arranged in piston cylinder, between guide rod 2 and fitting seat 8, be connected by spring 1 elasticity, fitting seat 8 is convenient to cylinder 7 and guide rod 2 is arranged in valve body 3, can not affect the sealing of valve.
Between described fitting seat 8 and guide rod 2, be provided with O type circle 6, improved sealability.
Described valve body 3 inner chambers are oval, are convenient to medium by valve body 3 inner chambers.
Among axial flow type check valve, can find, flap position can cause flap and air guide sleeve to open the variation in space in the process of side-to-side movement, this variation is constant at upstream extremity pressure, in the situation of downstream normality standard-sized sheet circulation, can cause the rate-of flow of downstream to follow flap unlatching space be the increase of a linearity or dwindle.
Therefore suppose that valve downstream is a fixed space open interior, when in use requiring perforate position to keep constant pressure medium or require downstream to need upstream extremity that specific medium deliverability is provided in the time that certain uses state, just need between safety check and use position, to arrange again pressure regulator or stable-pressure device, and the sealing configuration of the safety check of axial flow own just has the possibility that realizes pressure or flow control, just there has been the structural change as figure.
, therefore will between valve body 3 downstream and air guide sleeve 4, directly be connected with hole because reasons in structure cannot respond the pressure of downstream to be changed in conventional check valves, form independently sealing.The guide rod 2 of flap 5 forms a piston effect by O type circle 6 and cylinder 7.The variation of the pressure in downstream just can directly be reacted in piston cylinder like this, as disturbances back piston in-cylinder pressure changes thereupon, downstream pressure reduces, piston cylinder internal pressure reduces, guide rod 2 End Force are reduced, upstream extremity pressure is constant, the power that flap 5 upstream extremities cause is constant, so now flap 5 just can overcome spring 1 elastic force towards left movement, increase unlatching scope, increase downstream media supply, in this process, downstream pressure gos up gradually, cylinder pressure raises gradually, in order to maintain balance, just therefore step-down of spring 1 elastic force, namely spring 1 unclamps, flap 5 moves right the supplying media ability that reduces.Maintain the stable of valve body 3 upstream and downstream pressure by a kind of like this mode.
Because piston cylinder is seal space independently, if be set to a controlled external load in piston cylinder, valve opening degree has also become a kind of process that can external control, and valve mechanism has been realized the function of modulating valve.
Compared with prior art, axial flow of the present invention is relied on oneself pressure maintaining valve by the cooperation of cylinder 7, guide rod 2 and flap 5, pressure that can automatic regulating valve door upstream and downstream, thus ensure the stable supplying of medium.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
