Technical field
The utility model relates to valve member device technique field, particularly a kind of guide check valve.
Background technique
Switch stop valve is the industry equipment that is applied to fluid control, be used in the flow parameter of adjusting fluid in industrial control system, for controlling fluid cut-out or open-minded, and control uninterrupted or the valve type base components opening circuit of damming, by coordinating other valve members to be used in combination, there is the multiple use pattern such as switch and changes in flow rate.Current stop valve is often applied to the control of blocking of pressure duct, need to have and control faster sensitivity and response time still less, to avoid pipeline control to occur the safety and stability of misoperation and then protection total system.And existing switch Decompression valves still exists more shortcoming, complex structure, volume are larger, are subject to interior pressure to affect its cut-off action and automatically to control compatibility not strong, and break-in operation underaction, easily produces misoperation etc.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of compact structure, easy to operate guide check valve are provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of guide check valve described in the utility model, comprises valve body, and valve body both sides offer the inlet hole and the air outlet hole that are communicated with valve pocket, in described valve pocket, are provided with partition, and partition is provided with the valve opening that is communicated with inlet hole and air outlet hole; In the valve pocket of described partition both sides, be respectively equipped with piston and spool, piston is provided with connecting rod, and connecting rod one end is connected with the spool of below through valve opening; Described valve body upper end is provided with guide's valve gap, and pilot valve covers and is provided with the coil block coordinating with piston, and coil block is provided with terminal box.
Further, between described piston and guide's valve gap, be provided with spring.
Further, described spool is corresponding cuts off the tapered setting of a side, and the maximum diameter of spool is greater than the diameter of valve opening.
Further, described valve body lower end is provided with bottom, and bottom is located at the below of spool.
Further, the outer rim that described piston contacts with bullport is provided with Glais ring.
The utility model beneficial effect is: the utility model is rational in infrastructure, drive piston and then make spool stop up valve opening by pilot head, spring provides reset power to make it open valve to piston, in pressure duct, can control flexibly break-make, respond faster sensitivity better, realize precisely fast control requirement, can effectively avoid the misoperation of system.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of guide check valve described in the utility model, comprises valve body 10, and valve body 10 both sides offer the inlet hole 11 and the air outlet hole 12 that are communicated with valve pocket 13, is provided with and cuts off 15 in described valve pocket 13, cuts off 15 and is provided with the valve opening 16 that is communicated with inlet hole 11 and air outlet hole 12; In the valve pocket 13 of described partition 15 both sides, be respectively equipped with piston 19 and spool 17, piston 19 is provided with connecting rod 18, and connecting rod 18 one end are connected with the spool 17 of below through valve opening 16; Piston 19 is at the interior up and down and then band movable valve plug 17 of valve pocket 13, and spool 17 coordinate obstruction with valve opening 16 after cuts off the connected state between inlet hole 11 and air outlet hole 12; Described valve body 10 upper ends are provided with guide's valve gap 20, and guide's valve gap 20 is provided with the coil block 21 coordinating with piston 19, and coil block is provided with terminal box 22; Terminal box 22 coil block 21 of switching on is subjected to displacement piston 19 to change position, 20 of guide's valve gaps change the interior pressure of valve pocket 13 of piston 19 tops, and then the displacement resistance of piston 19 is reduced, and then realize the quick response of spool 17, improve overall control sensitivity.。
Between above-mentioned piston 19 and guide's valve gap 20, be provided with spring 23, coil block 21 power-off rear spring 23 provide initial kinetic energy to promote piston 19 and move down, spool 17 depart from valve opening 16 so that inlet hole 11 in air pressure reduce and promote further spool 17 to bottom offset.
The tapered setting of above-mentioned spool 17 corresponding partition 15 1 side, and the maximum diameter of spool 17 is greater than the diameter of valve opening 16, the conehead design of spool 17 can better shutoff valve opening 16, and the easy-to-use life-span is longer, the conehead surface of spool 17 is provided with wear-resisting glue-line, make to coordinate tightness higher between itself and valve opening 16, wear resistance is stronger.
Above-mentioned valve body 10 lower ends are provided with bottom 14, bottom 14 is located at the below of spool 17, bottom 14 adopts screw-thread fit with valve body 10, and then spool 17 for convenience detach, and adjust the spacing that coordinates between bottom 14 and valve body 10, can change the spacing between spool 17 and valve opening 16, and then change the response time of the present utility model.
