Preferably, an inner circumferential of damming is provided with airtight and watertight padding layer.
Preferably, in each layer via layer on cylinder of damming, number of openings is consistent.
Preferably, the aperture of each through hole in via layer is the most equal.
Preferably, spool includes plug and the connecting rod being connected with plug, and wherein, the bottom of plug is arc, Plug and valve seat are adapted for the closing to the communication channel between medium entrance passage and media outlet channel;Even The fur bundle that can stretch in through hole it is implanted with on the outer peripheral face of extension bar.
In the present invention, the inside of valve body is provided with medium entrance passage and media outlet channel, media outlet channel It is positioned at the top of medium entrance passage and leads to medium entrance channel connection, media outlet channel and medium entrance It is provided with valve seat at communicating passage between road;The cylinder that dams is positioned at media outlet channel, the one end of the cylinder that dams with Valve gap connects, and the other end is connected with valve seat, and an inner peripheral surface that dams is provided with multilamellar via layer, each layer via layer Vertical direction along the cylinder that dams is distributed, and every layer of via layer is provided with multiple through hole connected with the tube inner chamber that dams, Each through hole is distributed along the anchor ring of the cylinder that dams;In spool is arranged on the cylinder that dams and the periphery of spool and the cylinder that dams Inwall is fitted.Employing said structure designs, and operationally, spool is being dammed the present invention by the drive of valve rod Move up and down in Tong, when spool is during moving up, the cylinder that dams is blocked by spool Through hole is gradually opened, spool in the cylinder that dams on the height that moves the highest, via layer that the cylinder that dams is unlocked The most, rate-of flow is the biggest, otherwise, spool in the cylinder that dams on move height the lowest, dam The via layer being unlocked on cylinder is the fewest, and rate-of flow is the least, and due to the via layer on cylinder of damming Number of openings in number and every layer of via layer can be definite value, therefore, and can by calculating the open amount of through hole With the size of rate-of flow at accurate calculating.The present invention in the application, by control spool in the cylinder that dams Stretch and highly to the control of rate-of flow, and can effectively calculate the size of rate-of flow.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of regulation valve being easy to flow control that the present invention proposes.
Detailed description of the invention
Below, by specific embodiment, technical scheme is described in detail.
As it is shown in figure 1, the structural representation that Fig. 1 is a kind of regulation valve being easy to flow control that the present invention proposes Figure.
Reference Fig. 1, a kind of regulation valve being easy to flow control that the embodiment of the present invention proposes, including: valve body 1, Valve gap 2, spool 3, valve rod 4, the cylinder 5 that dams, valve seat 6 and actuator, wherein:
Valve gap 2 is positioned at the top of valve body 1 and fixing with valve body 1 is connected;The inside of valve body 1 is provided with medium Intake channel 11 and media outlet channel 12, media outlet channel 12 is positioned at the top of medium entrance passage 11 And connect with medium entrance passage 11, valve seat 6 is fixedly mounted on media outlet channel 12 and leads to medium entrance At communicating passage between road 11;The cylinder 5 that dams is positioned at media outlet channel 12, the one end of the cylinder 5 that dams Being connected with valve gap 2, the other end is connected with valve seat 6, and cylinder 5 inner peripheral surface that dams is provided with multilamellar via layer, respectively Layer via layer is distributed along the vertical direction of the cylinder 5 that dams, and every layer of via layer is provided with multiple and cylinder 5 inner chamber that dams The through hole 51 of connection, each through hole 51 is distributed along the anchor ring of the cylinder 5 that dams.
Fit with the inwall of the cylinder 5 that dams in spool 3 is arranged on the cylinder 5 that dams and the periphery of spool 3;Spool 3 It is connected with actuator by valve rod 4 and is moved up and down in the cylinder 5 that dams by actuating mechanism controls;Spool 3 Including plug 31 and the connecting rod 32 that is connected with plug 31, wherein, the bottom of plug 31 is arc, plug 31 and valve seat 6 be adapted for the envelope to the communication channel between medium entrance passage 11 and media outlet channel 12 Close.
Operationally, actuator promotes valve rod 4 to move up and down in the cylinder 5 that dams by the instruction received, And control spool 3 amount of moving up and down in the cylinder 5 that dams, when spool 3 is during moving up, cut The through hole 51 blocked by spool 3 in flow cartridge 5 is gradually opened, spool 3 in the cylinder 5 that dams on move height Spending the highest, the via layer that the cylinder 5 that dams is unlocked is the most, and rate-of flow is the biggest, otherwise, valve Core 3 in the cylinder 5 that dams on move height the lowest, the via layer that the cylinder 5 that dams is unlocked is the fewest, be situated between Mass flow amount is the least, and due to the through hole number of plies on cylinder 5 and through hole 51 quantity in every layer of via layer of damming Can be definite value, therefore, can accurate rate-of flow big at calculating by calculating the open amount of through hole 51 Little.And when in ring recess during plug 31 is in valve seat 6, medium entrance passage 11 and media outlet channel 12 Between communication channel be then in completely enclosed shape body.
In the present embodiment, in each layer via layer on cylinder 5 of damming, through hole 51 quantity is consistent and each in via layer The aperture of through hole 51 is the most equal;So that the calculating to rate-of flow, cylinder 5 inner circumferential of damming is additionally provided with sealing and fills out The bed of material 7, it is the tightst with what the inner circumferential of the cylinder 5 that dams was fitted to make spool 3, plays and seals and the effect of protection. Additionally, be implanted with the fur bundle 8 that can stretch in through hole 51 on the outer peripheral face of connecting rod 32 in the present invention, Spool 3, during moving up and down, drives connecting rod 42 to move, so that fur bundle 8 is in the mistake of movement In journey inswept in through hole 51, to avoid through hole 51 to block.
The present invention in the application, highly can be to medium stream by controlling the flexible in the cylinder 5 that dams of spool 3 The control of amount, and can effectively calculate the size of rate-of flow.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office Being limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to this The technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present invention Within the scope of.
