Description

Can end one-way valve
Technical field
The utility model relates to hydraulic control valve, relates in particular to a kind of by one-way valve.
Background technique
In hydraulic control system, one-way valve is very commonly used, and we open oil circuit and oppositely close oil circuit for realizing forward by present employed one-way valve, and function is single.But hydraulic system often has various different requirements, when keeping the one-way valve forward to open as requirement sometimes oil circuit is closed, and existing solution is stop valve to be installed in addition reach requirement on oil circuit.This method need be added valve on oil circuit, not only make the oil circuit design complicated more, artificially increases the leakage link of oil circuit, and increases workload to regular maintenance, has improved input and operating cost.
The model utility content
Technical problem to be solved in the utility model is the function singleness of existing one-way valve, provides a kind of by one-way valve, and this can close oil circuit along the one-way valve forward by one-way valve, has increased the function of one-way valve.
For solving the problems of the technologies described above, the utility model can end one-way valve, comprise valve body and poppet valve core, poppet valve core is positioned at the main valve hole of valve body, the end face of valve body is opened the forward filler opening, the forward oil outlet is opened in one side, and this can also comprise check valve spring, spring seat, seal ring, adjusting screw rod, nut and stop screw by one-way valve.
Poppet valve core connects check valve spring, and the fixedly connected spring seat of the check valve spring the other end, spring seat are installed in the end that adjusting screw rod is positioned at main valve hole, have circular groove on the adjusting screw rod body of rod, are set with seal ring in the groove, can prevent that oil spill from going out.
Adjusting screw rod is positioned at the outer end of main valve hole a nut, is adjacent to the valve body end face when screwing, and can prevent that adjusting screw rod is loosening, and adjusting screw rod and main valve hole are threaded.In order to limit the stroke of adjusting screw rod, on valve body, also have a tapped through hole, stop screw is installed in the hole.
For stop screw can effectively be worked, the described adjusting screw rod outside journal axle that ends one-way valve is to having restraining groove, and this restraining groove is located at and above-mentioned tapped through hole relevant position, and above-mentioned stop screw head is positioned at restraining groove.
For preventing vexed oil, this can have the anti-vexed groove more than two by the spring seat external diameter of one-way valve.
Working principle of the present utility model is: under normal conditions, adjusting screw rod is positioned at top, nut is locked it, by spring seat and check valve spring with the poppet valve core ejection on valve body hole, fluid enters from oil inlet P 1, utilizes hydraulic pressure to back down poppet valve core, arrive oil outlet PZ, otherwise oil enters from PZ, poppet valve core is compressed, thereby play the one-way valve effect; When the needs forward was closed one-way valve promptly as stop valve, adjusting screw rod was pressed downwardly onto the end, at this moment, adjusting screw rod, spring seat and poppet valve core closely contact mutually, by the screw-threaded coupling power between adjusting screw rod and the valve body screw thread, overcome P1 mouth hydraulic coupling, P1~PZ can be turn-offed.When adjusting screw rod is positioned at the neutral position, this valve place half-open position can play throttling action.This shows that the utility model can integrate two hydraulic element functions by one-way valve, and is easy to operate, cost-saved, reduces the pipeline connecting link, not only simplifies pipeline, and can reduce the hydraulic system leakage link.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-valve body, 2-poppet valve core, 3-spring, 4-spring seat, 5-seal ring, 6-adjusting screw rod, 7-nut, 8-stop screw, the anti-vexed groove of 9-.
Embodiment
Fig. 1 is a structural drawing of the present utility model, visible the utility model is a kind of by one-way valve among the figure, comprise valve body 1 and poppet valve core 2, poppet valve core 2 is positioned at the main valve hole of valve body 1, the end face of valve body 1 is opened forward oil inlet P 1, forward oil outlet PZ is opened in one side, and this can also comprise check valve spring 3, spring seat 4, seal ring 5, adjusting screw rod 6, nut 7 and stop screw 8 by one-way valve.
Poppet valve core 2 connects check valve spring 3, the fixedly connected spring seat 4 of check valve spring 3 the other ends, spring seat 4 is installed in the end that adjusting screw rod 6 is positioned at main valve hole, can move with adjusting screw rod 6, spring seat 4 external diameters have the anti-vexed groove 9 more than two, to prevent vexed oil.
Have circular groove on adjusting screw rod 6 bodies of rod, be set with seal ring 5 in the groove, can prevent that oil spill from going out as radial seal mechanism.
Adjusting screw rod 6 is positioned at the outer end of main valve hole a nut 7, is adjacent to valve body 1 end face when screwing, and can prevent that adjusting screw rod 6 is loosening, and adjusting screw rod 6 and main valve hole are threaded.
In order to limit the stroke of adjusting screw rod 6, on valve body 1, also have the tapped through hole of a band counterbore, stop screw 8 is installed in the hole, adjusting screw rod 6 outside journal axles are to having restraining groove, this restraining groove is located at and above-mentioned tapped through hole relevant position, and above-mentioned stop screw 8 heads are made cylinder, stretch in the restraining groove, block adjusting screw rod 6, it can not infinitely be retreated cause the accident.According to adjusting screw rod 6 diverse locations, play the function of one-way valve or stop valve.
