What this utility model can reach has the technical effect that
Compared with prior art, the triangle vavle with check-valves of the present utility model, the water inlet at triangle valve body is installed check-valves, be effectively prevent the situation of backwater, thus decrease the pollution of water in pipeline；
Compared with prior art, the triangle vavle with check-valves of the present utility model, the fixed form between check-valves and water inlet uses the structure of expansion piece, and this makes easy for installation, meanwhile, assembles more firm；
Compared with prior art, this utility model has the triangle vavle of check-valves, uses the check-valves of plastic material, and service life is longer.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view that this utility model has the triangle vavle of check-valves；
Fig. 2 is the sectional view that this utility model has the triangle vavle of check-valves；
Fig. 3 is the three-dimensional exploded view that this utility model has the check-valves of the triangle vavle of check-valves.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Refer to Fig. 1 to Fig. 3, this utility model provides a kind of triangle vavle with check-valves, including triangle valve body 1, described triangle valve body 1 is provided with water inlet 2, outlet 3 and water rate control mouth, spool 4 is set in water rate control mouth, described water inlet 2 is provided with check-valves 5, and described check-valves 5 includes valve chest 6, is movably bearing in valve chest 6 and passes through the valve body 8 that spring 7 loads, and has the securing member mated with water inlet 2 inwall and O outside described valve chest 6.
Described check-valves 5 is plastic material.
Described valve chest 6 includes the first housing 9 and the second housing 10, and described second housing 10 is set on the first housing 9, thus it is fixing to complete splicing；Securing member has multiple, is in the first housing 9 outer wall, for the expansion piece 11 turned-out relative to the first housing 9 outer wall.
Described first housing 9 includes supporting part 12 and has the Plug Division 13 of certain axial distance with supporting part 12, and be provided with the erecting bed 14 being connected with the second housing 10 in the outer end of Plug Division 13, expansion piece 11 is in the outer wall of Plug Division 13；Being connected by multiple floors 15 between described supporting part 12 and Plug Division 13, spring 7 one end is against supporting part 12, and the other end is against on valve body 8；Being provided with axis hole 16 on supporting part 12, valve body 8 includes sealing cap 17 and valve rod 18, and valve rod 18 realizes moving axially in axis hole 16, seals cap 17 and mates the import at the second housing 10, is provided with sealing ring 19 between described sealing cap 17 and import.
Described supporting part 12 is in bowl-shape, and center is provided with the spring fixed seat 20 of projection, and described axis hole 16 is located at spring fixed seat 20 center, and described spring 7 one end is enclosed within spring fixed seat 20 and is against the bottom of supporting part 12.
Described valve rod 18 includes center-pole 21 and is centrally located the support plate 22 circumferentially divided equally of bar 21 outer wall, and described support plate 22 has 4.
Triangle vavle of the present utility model, fills in the water inlet 2 of triangle valve body 1 by check-valves 5, and the first housing 9 second housing 10 inwardly is outwardly, because the effect of expansion piece 11, after check-valves 5 is filled in water inlet 2, fastness is high, and check-valves 5 is difficult to move in water inlet 2；Being equipped with external screw thread at the outlet 3 and water inlet 2 of triangle valve body 1, water inlet 3 realizes being connected with external water pipe, and outlet 3 realizes being connected with other water outlet equipments by flexible pipe, and water outlet equipment is usually cistern.
Operationally, open spool 4, current in water pipe have certain hydraulic pressure, its hydraulic pressure is more than the hydraulic pressure in triangle valve body 1, current wash the valve body 8 in check-valves 5 open, current enter from the import of the second housing 10, and the apopore through being collectively forming with Plug Division 13 by the floor 15 of the second housing 10, supporting part 12 flows out, and finally converge to the outlet of triangle valve body 1；After spool 4 is closed, hydraulic pressure in triangle valve body 1 is higher than the hydraulic pressure in water pipe, and now, the valve body 8 of check-valves 5 resets under the effect of spring 7 and realizes airtight with the sealing ring 19 of the second housing 10 import, thus the water completely cut off in triangle valve body 1 mixes with the water in water pipe, has cut off pollution channel.
A kind of triangle vavle with check-valves provided this utility model embodiment above is described in detail, principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to the technical scheme helping to understand disclosed in this utility model；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, the most all will change, in sum, this specification content should not be construed as restriction of the present utility model.
