Abstract
The invention provides an improved ultrahigh pressure cutoff foot control valve, which is well sealed, saves labor in treading, saves water resources because water returns back to a water tank through a water return hole when a treadle is loosened, and has a wide use range. The improved ultrahigh pressure cutoff foot control valve comprises a bottom plate, a protecting hood, the treadle, a valve body, a liquid outlet and a liquid inlet, wherein the front of the bottom plate is provided with the valve body; the treadle is arranged on the valve body through two cylindrical pins; the protecting hood covers the outside of the treadle and is arranged on the bottom plate; and a valve core is arranged inside the valve body. The improved ultrahigh pressure cutoff foot control valve is characterized in that one end of the treadle facing to the valve core is provided with a controlling device; an inner cavity of the valve body is provided with a guide sleeve and a valve seat in turn; the valve core is sleeved on the inner walls of the guide sleeve and the valve seat; the valve seat is compressed and fixed on the valve body by a threaded sleeve; and a spring on the other end of the valve core is connected with the inner wall of the threaded sleeve.
Description
(1) technical field
The present invention relates to the foot control valve field, be specially a kind of ultra-high pressure stopped foot pedal control valve of improvement.
(2) background technique
Existing foot control valve, its sealing is not in place, steps down relatively effort, and because the pressure of liquid self, and its liquid still can flow out when riding when not stepping on, thus waste water resource, and not being suitable for the cleaner and tidier working environment of environment, Applicable scope is little.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of ultra-high pressure stopped foot pedal control valve of improvement, its good seal.Step down laborsavingly, when foot-operated unclamping, its water is got back to water tank from backwater hole, the conserve water resource, and using scope is wide.
Its technological scheme is such: it comprises base plate, guard shield, pedal, valve body, liquid outlet, liquid entering hole, described base plate front portion is equipped with described valve body, described pedal is installed on described valve body by two straight pins, described pedal outer cup has described guard shield, described guard shield is installed on the described base plate, spool is installed on valve inner, it is characterized in that: described pedal locates to be equipped with controlling device over against one of spool, described valve inner cavity is equipped with guide pin bushing successively, valve seat, described guide pin bushing is set in spool, described valve seat is fixed in described valve body by swivel nut, is pressed with spring between the inwall of described spool other end and described swivel nut.
It is further characterized in that: described valve inner has feed pathway, liquid outlet channel, has osculum on the described valve seat and is communicated with liquid outlet channel, has the water inlet on the described swivel nut and is connected with feed pathway; Described liquid outlet channel is communicated with liquid outlet, and described feed pathway is communicated with liquid entering hole, and described controlling device comprises adjusting screw, nut, and described adjusting screw is installed on the pedal over against one of spool, and described nut sleeve is loaded on described adjusting screw.
In the said structure of the present invention, when it was foot-operated not in running order, spool was blocked valve seat and screw plug joint fully, liquid can't flow to spool and valve seat, the formed cavity inside of guide pin bushing, can not flow out from the fluid pipeline, liquid is got back to water tank from return port, can waste water resource; When foot-operated being operated, adjusting screw acts on spool, promotes spool, pressure spring, spool reach makes liquid flow into spool and valve seat, the formed cavity inside of guide pin bushing by feed pathway, liquid flows to liquid outlet channel by the osculum on the valve seat and flows out liquid outlet, achieves the goal, when pin unclamps, spring reset, valve core reset, spool are blocked valve seat and screw plug joint fully, and liquid does not flow out liquid outlet.Its good airproof performance, step down laborsaving, conserve water resource, and applied widely.
