Description
Technical field
the utility model relates to a kind of draining part and the drainage mechanism with this draining part.
Background technique
generally, in the valve body of fire hydrant, for emptying its inner ponding offers drainage channel conventionally, in the time that fire hydrant is closed, by drainage channel, ponding is discharged.But how being controlled at when fire hydrant is closed makes drainage channel just must do specialized designs to the structure of drainage channel in unimpeded state, existingly at drainage channel, valve is set, carry out draining by opening and closing valve, but need specially by valve open like this, cumbersome in operation.
Summary of the invention
an object of the present utility model is to provide a kind of draining part.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of draining part, there is a body, on described body, offer the drainage channel that runs through body, described drainage channel comprises one-level passage, secondary passage and three grades of passages, the internal diameter of described one-level passage is greater than described secondary passage internal diameter, the internal diameter of described secondary passage is greater than the internal diameter of three grades of described passages, between described one-level passage and secondary passage, forms one-level step surface, between described secondary passage and three grades of passages, forms two stage steps face.
preferably, described body outer circumferential face is provided with screw thread.
another object of the present utility model is to provide a kind of drainage mechanism.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of drainage mechanism, comprise described body, seal ring, elastic component and push and block part, described elastic component extends to secondary passage from the one-level passage of described body, one end of described elastic component is against on the two stage steps face of described body, the other end and described push and block part offset, described seal ring is connected on described elastic component, and can be fitted on the one-level step surface of described body.
preferably, described push and block part comprises the inner shield ring that is against the steel ball of the described elastic component the other end and pushes described steel ball.
on the drainage channel of further preferably, described body, offer the draw-in groove of establishing described inner shield ring for blocking.
preferably, described elastic component is spring.
because technique scheme is used, the utility model compared with prior art has following advantages:
drainage mechanism in the utility model can be arranged on realization in fire hydrant and automatically close, when fire hydrant is closed, drainage mechanism is opened automatically, and by the micro-pressure automatic opening-closing of water itself, it is reasonable in design, it is convenient to install and change, and has effectively improved the drainage efficiency of fire hydrant.
Brief description of the drawings
accompanying drawing 1 is the schematic diagram of draining part in the utility model;
accompanying drawing 2 is the schematic diagram of drainage mechanism in the utility model.
wherein: 1, body; 10, drainage channel; 100, one-level passage; 101, secondary passage; 102, three grades of passages; 11, one-level step surface; 12, two stage steps face; 13, screw thread; 14, draw-in groove; 2, seal ring; 3, spring; 4, steel ball; 5, inner shield ring.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described:
a kind of draining part as shown in Figure 1, there is a body 1, on body 1, offer the drainage channel 10 that runs through body 1, wherein: drainage channel 10 comprises one-level path 10 0, secondary passage 101 and three grades of path 10s 2, the internal diameter of one-level path 10 0 is greater than secondary passage 101 internal diameters, the internal diameter of secondary passage 101 is greater than the internal diameter of three grades of path 10s 2, between one-level path 10 0 and secondary passage 101, form one-level step surface 11, between secondary passage 101 and three grades of path 10s 2, form two stage steps face 12.In addition, body 1 outer circumferential face is provided with screw thread 13.
a kind of drainage mechanism as shown in Figure 2, it comprises body 1, seal ring 2, elastic component and push and block part.In the present embodiment: elastic component is spring 3; Push and block part comprises steel ball 4 and inner shield ring 5.It is as follows that it arranges relation: spring 3 prolongs 100 from the one-level passage of body 1 and extends secondary passage 101, one end of spring 3 is against on the two stage steps face 12 of body 1, the other end and steel ball 4 offset, seal ring 5 is connected on spring 3, and can be fitted on the one-level step surface 11 of body 1, inner shield ring 5 pushes away steel ball 4, and offers draw-in groove 14 on the drainage channel 10 of body 1, inner shield ring 5 is fastened in draw-in groove 14, guarantees that steel ball 4 can not drop out from drainage channel 10.
when use, drainage mechanism can be arranged on the drainage channel of fire hydrant by the screw thread 13 on body 1, in the time that fire hydrant is opened, because hydraulic pressure in valve body increases, make steel ball 4 Compress Springs 3, spring 3 pushes seal ring 2 one-level step surface 11 is sealed, and drainage channel 10 cannot carry out draining; After fire hydrant is closed, in valve body, hydraulic pressure disappears, and steel ball 4 loses thrust, and spring 3 unclamps, and between seal ring 2 and one-level step surface 11, produces gap, and drainage channel 10 allows the discharge of ponding.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
