The utility model has the advantages that the entire structural element is made of rigid plastic, thereby the utility model is wearable, collision resistant and chemicals resistant, the service life is long, the quantity of flow is large, the combined installation, the disassembly and the maintenance are convenient.
Description
(1) technical field:
The utility model relates to a kind of liquid conducting pipes accessory, especially relates to a kind of rotary-open type quick opening valve of opening fast on the liquid conducting pipes or closing of being used for.
(2) background technique:
At present, be used on the liquid conducting pipes snap switch valve of cool and hot water pipe particularly and mainly adopt quick opening valve based on ceramic core, this valve main structure is that two ceramic plate sealings are overlapping up and down, have tiny discharge orifice at two ceramic plates up and down, following sheet is fixed, last slice be connected with handle, and the rotation by handle drives last slice rotation, when rotating 90 °, two discharge orifice is relative up and down, at this moment, and valve opening, current pass through, when 90 ° of backward rotation, then two discharge orifice dislocation discharge orifices are sealed mutually up and down, at this moment, valve closing then, current stop.This valve uses quick, laborsaving, convenient, but that its shortcoming is a ceramic plate is frangible.This is owing to contain the tiny grains of sand unavoidably in the current, in case when sand grains enters up and down between two ceramic core coincidence faces, be easy to then that stuck to cause ceramic chip to be squeezed broken with two ceramic chips up and down, thereby the ceramic core life-span is shorter, spool needs often to change.
(3) summary of the invention:
In order to overcome the problem that ceramic core is frangible and current are little in the quick opening valve, the utility model provides a kind of rotary-open type quick opening valve that designs a kind of new structure with new material; The technological scheme that the utility model adopted realizes in the following manner: a kind of rotary-open type quick opening valve, it mainly comprises valve body, be positioned at the valve rod of valve body, the switch knob that is connected and controls the valve rod rotation with valve rod, with the valve rod socket, moved up and down and the spool of shutoff valve body import and export by valve rod control, wherein valve rod and spool are connected as a single entity by its related spiral hole with along spool guiding Xiao that spiral hole moves, spool is connected with spool guiding Xiao who moves up and down along guiding groove by the vertical up and down guiding groove of valve body with valve interior wall, and the spool bottom is with " O " type rubber seal with gap between sealed valve core and the import and export.
Spiral hole is positioned on the valve rod barrel, and spiral hole angle of rotation from top to bottom is 90 °, and spool guiding Xiao is positioned at spool outer wall top.
Spiral hole on the valve rod outer wall is two, the relative sense of rotation unanimity in its position, and the spool that matches with two spiral hole guiding Xiao is two and is positioned at spool outer wall top relative position.
Spiral hole can be the spiral chute that is positioned on the spool outer wall, and spool guiding Xiao is positioned at valve rod inwall bottom.
Two spool guiding Xiao that the position is relative are arranged at spool outer wall bottom, and valve interior wall has two vertical up and down guiding grooves of spool that the position is relative, and guiding Xiao is positioned at guiding groove.
Two vertical up and down guiding grooves of spool can be positioned at the spool outer wall, and two spool guiding Xiao are positioned on the valve interior wall.
Valve rod upper end is a tetragonal body, and a cubic hole that fastens with tetragonal body is arranged on the switch knob body, and there is a breach on the tetragonal body top, studs with one " fourth " font handle fixed card in the breach switch knob body closely is connected with valve rod.
An adapter sleeve is housed so that overall structure is connected tight, complete between valve rod and the valve body.
Valve rod top is with " O " type rubber seal with sealed valve stem and adapter sleeve gap, also is with " O " type rubber seal on the valve rod with sealed valve stem and valve body gap.
Good effect of the present utility model is that the total part all is a rigid plastics, thereby wear-resisting, anti-collision, acid resistant alkali, and long service life, and flow is big, and stack mounting, dismounting, maintenance are all convenient.
(4) description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is the appearance structure schematic representation of valve rod of the present utility model.
Fig. 3 is a spool appearance structure schematic representation of the present utility model.
(5) embodiment:
By Fig. 1, Fig. 2, Fig. 3 as can be seen, valve inleting water mouth of the present utility model is on the right side, water outlet is on a left side, valve rod 6 is arranged in the valve body, with valve rod 6 sockets, be subjected to valve rod control to move up and down and stop up the spool 10 of valve body import and export, its valve rod 6 and spool 10 are by two spiral hole on the valve rod 67 and be positioned at two spools guiding Xiao 9 that spool upper edge spiral hole 7 moves and be connected as a single entity, spool 10 and valve interior wall are by the relative vertical guiding groove 12 and be positioned at two relative spools guiding Xiao 11 of position that spool upper edge guiding groove moves up and down and be connected up and down in two positions of valve interior wall, and the spool bottom is with " O " type rubber seal 8 with gap between sealed valve core 10 and the import and export; Valve rod 6 upper ends are tetragonal bodies, and a cubic hole that fastens with tetragonal body is arranged on the switch knob body 2, and there is a breach on the tetragonal body top, studs with one " fourth " font handle fixed card 1 in the breach switch knob body 2 closely is connected with valve rod 6; One adapter sleeve 4 also is housed so that overall structure connects tight, complete on the valve rod 6; Valve rod 6 tops are with " O " type rubber seal 3 with crack between sealed valve stem 6 and the adapter sleeve, also are with " O " type rubber seal 5 on the valve rod 6 with gap between sealed valve stem 6 and the valve body.
The rotating switch handle body was 90 ° when the utility model used, the switch knob body drives valve rod and rotates 90 °, because the spool of spool lower end moves up and down the vertical up and down guiding groove of two vertical spools that guiding Xiao is positioned at valve body, thereby the qualification spool can only move up and down, therefore spiral hole forces spool to move down, stop up import and export until the spool lower end, valve is in closed condition, when switch knob body during to 90 ° of opposite spins, spiral hole forces spool to move up, at this moment, valve is in opening state.
