Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.The good valve of work can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Quickening along with socioeconomic development and people's rhythm of life, automobile obtains applying more and more widely in daily life and work, in automobile making, need at present to use the control valve of controlling gas circuit, existing control valve design is reasonable not, has reduced sealing reliability.
The problem existing in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of push buttonvalve [application number: 200620102054.X], comprise valve body, valve gap, control spool, valve gap is provided with the axis hole passing through for controlling spool, valve body is provided with suction port, air outlet, relief opening and control spool cavity, suction port and air outlet are staggered to be located at valve body side and to be communicated with control spool cavity, relief opening is communicated with control spool cavity bottom, described control spool comprises little core body and the large core body that stepped ramp type arranges, the large core body in bottom is provided with the annular recess that can be communicated with suction port and air outlet, large core body two ends are provided with seal ring and lower seal, shaft hole diameter on described valve gap is less than large core diameter, when the control large core body of spool upper end is pulled to described axis hole place, described lower seal is between suction port and air outlet.
Such scheme has improved prior art to a certain extent.But it is reasonable not that this scheme still exists design, cannot be applicable to special structure, such as technical problems such as tracheae angle are inadequate.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, the improved type push buttonvalve that using effect is good.
For achieving the above object, the utility model has adopted following technical proposal: this improved type push buttonvalve, comprise valve body and button, it is characterized in that, described valve body is provided with air outlet and the suction port that is tilted to lower setting, and the opposed distribution of air outlet and suction port, in described valve body, be provided with the control mechanism that is communicated with or seals air outlet and suction port when can work as button pressed downwards and circumferentially rotating, described control mechanism comprises being arranged on and between air outlet and suction port, is provided with the spool being connected with button, in described valve body, being provided with can the axially movable restraining groove of limiting valve core, annular protrusion and the restraining groove of described spool upper end sidepiece match, described button lower end is connected with push rod one end, this push rod the other end is arranged in spool, described spool below is provided with the spring that is resisted against spool underpart.
Further, can the axially movable restraining groove of limiting valve core owing to being provided with in valve body, annular protrusion and the restraining groove of described spool upper end sidepiece match, thereby can make spool can effectively prevent the axial displacement that the impact because of gas produces.
In above-mentioned improved type push buttonvalve, between described button and valve body, be provided with the gap that can make button pressed downwards rotation, between described button and valve body, be also provided with button rotation limit structure.
In above-mentioned improved type push buttonvalve, described valve body upper end is provided with capping, and described button is arranged in capping, between described capping and valve body, is provided with seal ring.
In above-mentioned improved type push buttonvalve, described spring top is provided with the seal ring between spool underpart and valve body.
Compared with prior art, the advantage of this improved type push buttonvalve is: 1, reasonable in design, simple in structure, using effect is good.2, good seal performance, is not easy to occur gas leakage, uses easy to operate.3, protecting against shock is effective, not fragile, has improved Security.
