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 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, well known common.Existing one-way throttle valve is unreasonable because structure arranges, and when adjusting gas flow, cannot meet the movement velocity of executive component, thereby affect the total quality of product, is necessary existing one-way throttle valve effectively to improve.
Summary of the invention
The object of the invention is to defect 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 valve body, on described valve body, form suction port, valve pocket and air outlet, in described valve core case, form spool chamber, described spool chamber is communicated with valve pocket by valve port, described suction port is communicated with spool chamber by upper runner, in described spool chamber, can be provided with up or down spool, spool bottom setting corresponding to valve port, on spool, be fixedly connected with screw rod, described screw rod upper end is connected with nut through the screw on valve core case, described valve pocket bottom is provided with bonnet nut, described suction port is communicated with valve pocket by lower flow channel, lower flow channel place correspondence is provided with sealing seat, described sealing seat and bonnet nut are provided with Compress Spring.
Further, on described screw rod, be equipped with and spell tight nut.
Further, described spool bottom periphery is provided with seal ring.
Beneficial effect of the present invention is: suction port of the present invention is communicated with spool chamber by upper runner, in described spool chamber, can be provided with up or down spool, spool bottom setting corresponding to valve port, described valve pocket bottom is provided with 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, and during unlatching, the equal air inlet of upper runner and lower flow channel, can effectively meet the movement velocity of holding rough element.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
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 valve body 7, and described valve body 7 and valve core case 3 form agent structure of the present invention.
On described valve body 7, form suction port 5, valve pocket 11 and air outlet 12, form spool chamber 16 in described valve core case 3, and described spool chamber 16 is communicated with valve pocket 11 by valve port 13, and described suction port 5 is communicated with spool chamber 16 by upper runner 4.Described suction port 5 is communicated with valve pocket 11 by lower flow channel 6.
In described spool chamber 16, can be provided with up or down spool 15, the setting corresponding to valve port 13 of spool 15 bottoms, spool 15 is mainly used in opening and closing valve port 13, for connection or close 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 for opening and closing being communicated with between suction port 5 and valve pocket 11.
On described spool 15, be fixedly connected with screw rod 17, described screw rod 17 upper ends are connected with nut 1 through the screw on valve core case 3, and described valve pocket 11 bottoms are provided with bonnet nut 10.Nut 10 and screw rod 17 are for driving spool 15 to move up and down.On described screw rod 17, be equipped with and spell tight nut 2, screw rod 17 is transferred to desired location and fixes with spelling tight nut 2, make the flow of air outlet 12 outputs consistent.
Working principle: shown in Fig. 1, the present invention, in closed condition, while needing unlatching of the present invention, is rotated counterclockwise nut 1 and screw rod 17, on spool 15, move, now suction port 5 is with valve pocket 11 in connected state, 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 through air outlet, 12 discharge outside the present invention.Need close when of the present invention, turn clockwise nut 1 and screw rod 17, spool 15 moves down, and suction port 5 is with valve pocket 11 in closed condition, 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 is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
