Abstract
The utility model relates to a constant pressure cushion non-return water pump, which comprises a water pump and pressure reducing valve, wherein voltage stabilizing water inlet tube of the pressure reducing valve is provided with a check valve, the check valve comprises a check valve body, a valve plug, a spring and a valve cap, the valve body and the valve cap are all provided with through holes, the check valve body is provided with an inner tube, the inner tube is communicated with the through hole of the check valve body, the spring is sleeved on the valve plug, the spring and the valve plug are arranged in the inner tube of the valve body together, the check valve body is fixed on a pressure reducing valve body of the pressure reducing valve water inlet, the check valve body through hole is communicated with water inlet of the pressure reducing valve, the valve cap is fixed in the voltage stabilizing water inlet tube. The structure of the check valve and the pressure reducing valve combining with the water pump guarantees normal work of the water pump, saves space and especially is convenient for users, which eliminates problem caused by installing the check valve by oneself, decreases cost and increases the function of protecting water backflow when the water pump is not working.
Description
One. technical field
This novel a kind of water pump, particularly a kind of automatic constant-pressure water pump of relating to.
Two. background technique
The constant voltage water pump is the water pump that water pump and reduction valve is made for one, this pump has saved water pump when installing and using, and also will join the trouble of reduction valve again, is 02294674.8 as China Patent No., although this patent is made one with water pump and reduction valve, for the user brings lot of advantages, but in actual use, this constant voltage water pump still can not use separately, also must join safety check outward, when guaranteeing that water pump quits work, water can not flow backwards, and still can not make things convenient for the user fully.
Three. summary of the invention
This novel purpose is a kind of automatic constant-pressure buffering stop waterback pump of design, thereby reaches the purpose of the installation and the use of real simplification water pump.
This novel structure is such: on the voltage stabilizing intake pipe of constant voltage water pump reduction valve, safety check is set, safety check is made up of check valve body, spool, spring, bonnet, be equipped with through hole on valve body and the bonnet, check valve body has inner chamber, inner chamber communicates with the through hole of check valve body, spring is set on the spool, place the inner chamber of check valve body together, check valve body is fixed on the reducing valve body of water intake of reduction valve, the check valve body through hole communicates with the water intake of reduction valve, and bonnet is fixed on the voltage stabilizing intake pipe.Safety check also can directly be fixed on the voltage stabilizing intake pipe.
Adopt said structure, safety check, reduction valve and water pump become one, so both guaranteed the proper functioning of water pump, saved the space again, particularly made things convenient for the user, removed the trouble that independent installation safety check brings from, and reduced cost, when both guaranteeing constant voltage water pump advantage, increased the function that prevents aqueous reflux when water pump quits work again.

Five. embodiment
As shown in Figure 2, for the A-A of Fig. 1 cuts open, it is the sectional drawing of reduction valve part in the water pump, safety check 13 is connected on the voltage stabilizing intake pipe 11 of reduction valve, check valve body 9 directly is fixed on the reducing valve body 3 at water inlet 1 place of reduction valve, have through hole 12 on the reducing valve body 3 at reduction valve water inlet 1 place, communicate with the water inlet 1 of reduction valve to guarantee safety check through hole 10.
Safety check is made up of check valve body 9, spool 7, spring 8, bonnet 6 as shown in Figure 3, be equipped with through hole 10 and through hole 4 on valve body 9 and the bonnet 6, check valve body 9 has inner chamber 5, inner chamber 5 communicates with the through hole 10 of check valve body, also have through hole 4 on the bonnet 6, spring 8 is set on the spool 7, place the inner chamber 5 of check valve body 9, spool 7 is under the effect of spring 8, can in inner chamber 5, move, spool 7 communicates and closure by hydraulic pressure control reduction valve epicoele 12 and reduction valve water inlet 1, and Fig. 3 is the safety check closed state, and spool 7 is kept out in inner chamber 5 bottoms.
When pump working, safety check is in opening state, reduction valve epicoele 12 is communicated with reduction valve water inlet 1, to keep the constant voltage of water pump, when water pump cuts out, because the pressure of reduction valve epicoele 12 keeps out in check valve body inner chamber 5 bottoms spool 7 greater than the pressure at reduction valve water inlet place, reduction valve epicoele 12 and reduction valve water inlet 1 closure are to prevent the refluence of water.
Safety check also can directly be connected on the pipeline of voltage stabilizing intake pipe.
Claims (2)
1 one kinds of constant voltage buffering stop waterback pumps, form by water pump and reduction valve, it is characterized in that: on the voltage stabilizing intake pipe of reduction valve, safety check is set, safety check is made up of check valve body, spool, spring, bonnet, be equipped with through hole on valve body and the bonnet, check valve body has inner chamber, inner chamber communicates with the through hole of check valve body, spring is set on the spool, places the inner chamber of check valve body together, and check valve body is fixed on the reducing valve body of water intake of reduction valve, the through hole of check valve body communicates with the water intake of reduction valve, and bonnet is fixed on the voltage stabilizing intake pipe.
2 constant voltage buffering stop waterback pumps according to claim 1, it is characterized in that: safety check also can directly be fixed on the voltage stabilizing intake pipe.
