Abstract
The invention relates to the technical field of a valve body, in particular to a one-way throttle valve, comprising a valve body and a spool seat, wherein the spool seat is arranged on the valve body; an air inlet, a valve cavity and an air outlet are formed in the valve body; a spool cavity is formed in the spool seat; the spool cavity is communicated with the valve cavity through a valve port; the air inlet is communicated with the spool cavity through an upper channel; a spool can be arranged in the spool cavity in an up-and-down movement way; the bottom part of the spool and the valve port are correspondingly arranged; a screw rod is fixedly connected onto the spool; the upper end of the screw rod passes through a screw hole in the spool seat to be connected with a screw cap; the bottom part of the valve cavity is provided with a rear cover screw cap; the air inlet is communicated with the valve cavity through a lower channel; a seal seat is correspondingly arranged at the lower channel; and the seal seat and the rear cover screw cap are provided with a compression spring respectively. The one-way throttle valve is provided with the upper channel and the lower channel; and in the opening state, the air enters the upper channel and the lower channel, so that the movement speed of an actuating element can be effectively met.
Description
Technical field
The present invention relates to the valve body technical field, particularly a kind of one-way throttle valve.
Background technique
One-way throttle valve is a kind of of valve body, and is well known common.Existing one-way throttle valve is unreasonable because structure arranges, and when adjusting gas flow, can't satisfy the movement velocity of executive component, thereby affect the total quality of product, is necessary existing one-way throttle valve is effectively improved.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, a kind of compact structure is provided, the one-way throttle valve that movement velocity is fast is set rationally.
For achieving the above object, the present invention is by the following technical solutions:
A kind of one-way throttle valve of the present invention, comprise valve body, be provided with the valve core case on the valve body, form suction port on the described valve body, valve pocket and air outlet, form spool chamber in the described valve core case, described spool chamber is communicated with valve pocket by valve port, described suction port is communicated with spool chamber by upper runner, can be provided with up or down spool in the described spool chamber, the spool corresponding setting with valve port in bottom is fixedly connected with screw rod on the spool, the screw that described screw rod upper end is passed on the valve core case is connected with nut, described valve pocket bottom is provided with the bonnet nut, described suction port is communicated with valve pocket by lower flow channel, and lower flow channel place correspondence is provided with sealing seat, and described sealing seat and bonnet nut are provided with Compress Spring.
Further, be equipped with the tight nut of assembly on the described screw rod.
Further, periphery is provided with seal ring bottom the described spool.
Beneficial effect of the present invention is: suction port of the present invention is communicated with spool chamber by upper runner, can be provided with up or down spool in the described spool chamber, the spool corresponding setting with valve port in bottom, described valve pocket bottom is provided with the bonnet nut, described suction port is communicated with valve pocket by lower flow channel, lower flow channel place correspondence is provided with sealing seat, and described sealing seat and bonnet nut are provided with Compress Spring.The present invention is provided with upper runner and lower flow channel, during unlatching, and the equal air inlet of upper runner and lower flow channel, but to satisfy effectively is held the movement velocity of rough element.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of one-way throttle valve of the present invention comprises valve body 7, is provided with the valve core case 3 on the valve body 7, and namely described valve body 7 and valve core case 3 consist of agent structure of the present invention.
Can be provided with up or down spool 15 in the described spool chamber 16, spool 15 bottoms and valve port 13 corresponding settings, spool 15 is mainly used in opening and closing valve port 13, is used for being communicated with or closing suction port 5 and air outlet 12.The preferred described spool 15 bottom peripheries of the present invention are provided with seal ring 14, effectively increase air-tightness of the present invention.Described lower flow channel 6 place's correspondences are provided with sealing seat 8, and described sealing seat 8 is provided with Compress Spring 9 with bonnet nut 10, and sealing seat 8 is used for opening and closing being communicated with between suction port 5 and the valve pocket 11.
Be fixedly connected with screw rod 17 on the described spool 15, the screw that described screw rod 17 upper ends are passed on the valve core case 3 is connected with nut 1, and described valve pocket 11 bottoms are provided with bonnet nut 10.Nut 10 and screw rod 17 are used for driving spool 15 and move up and down.Be equipped with on the described screw rod 17 and piece together tight nut 2, screw rod 17 is transferred to desired location and uses the tight nut 2 of assembly to fix, make the flow of air outlet 12 outputs consistent.
Working principle: shown in Figure 1, the present invention is in closed condition, when needing unlatching of the present invention, is rotated counterclockwise nut 1 and screw rod 17, move on the spool 15, this moment, suction port 5 was in connected state with valve pocket 11, and gas carries out valve pocket 11 from suction port 5, and valve pocket 11 internal air pressures raise, crush seal seat 8 moves down, lower flow channel 6 is opened, and a gas gas enters valve pocket from lower flow channel 6, and 12 discharge outside the present invention through the air outlet.Need close when of the present invention, turn clockwise nut 1 and screw rod 17, spool 15 moves down, and suction port 5 is in closed condition with valve pocket 11, and valve pocket 11 internal air pressures reduce, and sealing seat 8 moves under the effect of Compress Spring 9, sealing lower flow channel 6, the present invention closes.
The above only is preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
