Compressed spring 10, the second connector 8 and 9 phase of stationary nozzle are housed between spool 5 lower boss A and the blind hole B of 8 inner cavity of the second connector
Even, water outlet that nozzle water inlet line 1 is connected with the first connector 2 and 3 centre bore of check valve body, 8 centre bore of the second connector, consolidate
The water inlet centre bore for determining nozzle 9 constitutes concentric through-hole channel structure.
Check valve body 3, one-way valve seat 6, nonreturn valve core 5 and the compressed spring 10 constitutes one-way valve structures.
There are external screw thread, 3 top of check valve body to have internal thread, the outer spiral shell of the first connector 2 outside the lower part of first connector 2
Line links together with 3 upper internal threaded of check valve body, and the cavity of 3 lower part of check valve body has internal thread, 8 top of the second connector to have
External screw thread, 3 lower internal thread of check valve body and the external screw thread of the second connector 8 link together, and constitute easy disassembly structure.
The lower part of first connector 2 is equipped with the first gasket for preventing leak with the top junction of check valve body 3
The top junction of circle 11, the lower part of check valve body 3 and the second connector 8 is equipped with the second seal washer 7 for preventing leak.
Third seal washer 4 is housed between the nonreturn valve core 5 and one-way valve seat 6.
The stationary nozzle 9 be Patent No. 200510048461.7 " cyclone fine mist spray head " or
200510048460.2 " high pressure fine mist combination type spray head ".
The utility model structure is it can be seen from above structure, and the first connector is welded with below nozzle water inlet line 1
2, external screw thread is processed into the lower part of the first connector 2, is connected with each other with the internal thread on 3 top of check valve body, water inlet line 1, first
There is through-hole to be interconnected between connector 2, check valve body 3, there is the first gasket in the junction between the first connector 2, check valve body 3
Circle 11 is sealed, and prevents leak.
3 central cavity of check valve body is provided with one-way valve seat 6, and the inner cavity of one-way valve seat 6 is provided with nonreturn valve core 5, unidirectionally
The internal thread of 3 lower cavity of valve body and the external screw thread on 8 top of the second connector for being connected and fixed nozzle 9 are connected with each other, in check valve
