Abstract
The invention discloses a pressure filtering valve which comprises a valve body, a valve cover and a valve core, wherein one end of the valve body is provided with an inlet; a valve core cavity and a channel are formed in the valve body; two ends of the valve core are respectively communicated with the inlet and the outlet; one end of the channel is respectively communicated with one end of the valve core cavity; the other end of the channel is respectively communicated with the other end of the valve core cavity; the valve core is arranged in the valve core cavity; the valve core is connected with an elastic element; and when fluid does not exist in the valve cavity, the channel is communicated with the inlet and the outlet through the valve cavity. The pressure filtering valve is simple in structure, high in instantaneous action, low in failure rate and low in cost.
Description
Technical field
The present invention relates to a kind of pressure and consider the ripple valve, especially can slacken the valve of pipeline pressure fluctuation.
Background technique
As everyone knows, the hydraulic-pneumatic transmission system is used on a large scale in actual production, and the pressure stability of pipeline plays crucial effects to the operation of whole system in the course of the work, fluid impact not only influences workmanship but also can cause damage by system device, so that keeps pipeline pressure is stable particularly important to whole hydraulic-pneumatic system, existing also have part to prevent the valve that pipeline pressure impacts.
Such as Chinese patent: water hammer-less valve (CN 101341359 A), relate to water hammer-less valve, move up and down the air pressure drive-type valve of valve body folding stream by the driving of pneumatic-typed driving mechanism, and when fluid impact takes place, suppress the inhibition mechanism that valve body rises.Suppressing mechanism comprises: be fixed in driving mechanism top and running shaft stepper motor down; Be connected with the running shaft of stepper motor, rise along with a direction rotation of running shaft, and the vertical motion element that descends along with counter-rotating; Detect contacted lower end, the upper end portion Detecting element of the center-pole that when above-mentioned vertical motion element descends, is connected with described valve body body; Stepper motor is rotated to a direction, when stopping to gas, make the stepper motor counter-rotating, and when the lower end Detecting element detects, send the control gear of stop signal to stepper motor.
But foregoing invention is utilized the electro motion control valve closure, and structure is comparatively complicated, and rate of fault is higher in use, the cost height, and volume is big.
Summary of the invention
Comparatively complicated in order to solve existing structure, rate of fault is higher in use, the cost height, and bulky shortcoming the invention provides a kind of pressure and considers the ripple valve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pressure is considered the ripple valve, its composition comprises: valve body, valve gap, spool, valve body one end is provided with import, is provided with spool chamber and passage in the valve body, and the two ends of spool are communicated with import and outlet respectively, one end of passage is communicated with spool chamber one end respectively, the other end of passage is communicated with the other end of spool chamber, is provided with spool in the spool chamber, and spool is connected with elastic element, during no fluid, passage is by valve pocket connection import and outlet in the valve pocket.
Further described, spool is made of import piston, outlet piston and the connecting rod that connects two pistons.
Further described, connecting rod one end is provided with projection, and connecting rod the other end cover has elastic component, and is provided with the baffle plate that removably connects with valve body between elastic element and projection.
Further described, elastic element is spring.
Further described, channel middle is communicated with the valve body end face, and connection place is provided with the valve gap that is connected with valve body.
The invention has the beneficial effects as follows: simple in structure, wink, moving property was good, and rate of fault is low, and cost is low.

Embodiment
Below in conjunction with embodiment of accompanying drawing narration, the invention will be further described.
In the drawings, valve body 5 one ends are provided with import 12, be provided with spool chamber 13 and passage 3 in the valve body 5, the two ends of spool are communicated with import 12 and outlet 6 respectively, one end of passage 3 is communicated with spool chamber 13 1 ends respectively, the other end of passage 3 is communicated with the other end of spool chamber 13, be provided with spool in the spool chamber 13, spool is by import piston 11, outlet piston 7 and connecting rod 8 formations that connect two pistons, connecting rod 8 is with spring 10 near import piston 11 1 ends, between spring 10 and outlet piston 7, be provided with baffle plate 16, one end of baffle plate 16 is absorbed in the groove 14 of spool one side, and the other end of baffle plate 16 stretches out valve body 5 and is fixed on the valve body 5 by fastening screw trip bolt 9, and baffle plate 16 is provided with oval shape gap 15 near an end of groove 14, during normal mounting, connecting rod 8 passes gap 15.Passage 3 middle parts are communicated with valve body 5 end faces, and connection place is provided with the valve gap 2 that is connected with valve body 5, and valve body 5 tops are provided with tapped hole 17, and valve gap 2 is pressed on valve body 5 end faces by hold-down bolt 1, also are provided with between valve gap 2 and valve body 5 end faces to prevent the seal ring 4 that leaks.When no fluid or import 12 equated with the pressure of outlet 6 in import 12 and the outlet 6, passage 3 was communicated with import 12 and outlet 6 by spool chamber 13.
During work; fluid flows into from import 12; and inlet passage 3 promotes and closes outlet 6 with spool to outlet 6 directions simultaneously; when fluid by contacting with the outlet piston 7 of the spool the other end behind the passage 3, spool reduces and slowly sets back suffered making a concerted effort, and rebulids balance; exporting 6 simultaneously opens fully; when pressure pulse appearred in pipeline, spool both sides balance was broken, and spool moves to protect the pressure smaller conduit to the less end of pressure.
