Out)；The valve body 1 is also provided with water inlet 13 and water outlet 14, the valve core channel 4 respectively with the water inlet 13 and cross water
Channel connection, the valve chamber 6 are connected to the water passage and water outlet 14 respectively.
The spool pressure regulating device includes reset spring 31 and adjusting screw rod 32, described 31 one end of reset spring and is adjusted
Section screw rod 32 is in contact, and the other end is in contact with valve core connector.
In conjunction with Fig. 4 and Fig. 5, the valve core connector includes spool connecting shaft 5 and cartridge cover 7, and the cartridge cover 7 is set to valve
The end of core connecting shaft 5 is equipped with pre-determined distance between the cartridge cover 7 and valve core channel 4, so that valve core connector and spool are logical
Water passage is formed between road 4.Preferably, the pre-determined distance is 3mm-50mm, and more preferably, the pre-determined distance is 10mm.
The valve core connector is additionally provided with limiting groove 52, and the limiting groove 52 is set to the reset spring 31 and connect with the spool
Part touching position, to constrain the end position of reset spring 31.
The utility model is easier to load and unload and maintenance, the valve body include valve upper cover 11 and valve body lower cover 12 in order to make,
The valve upper cover 11 and valve body lower cover 12 are detachable.Preferably, the valve body lower cover 12 is also equipped with decoration threaded cap 15,
The aesthetics of water check valve is turned up.
The switching spool axis 5 is set to the valve upper cover 11, and the spool pressure regulating device is set under the valve body
Lid 12.Internal screw thread road 16 is offered in the valve body lower cover, the adjusting screw rod 32 is connect with the internal screw thread road 16.The valve
Core switch shaft 2 is threadedly coupled through the valve upper cover 11 and with the valve upper cover 11.Optimally, the switching spool axis 2
It is equipped with turn-knob handle 21, to facilitate the turn-knob of the switching spool axis 5.
In order to improve the leakproofness of water check valve, the valve core connector further includes detent disk 51 and valve core seal ring 8, described
Valve core seal ring 8 is sheathed on the spool connecting shaft 5 and is set between the detent disk 51 and sealing cover 8.The cartridge cover 7 with
The spool connecting shaft 5 connects, and the cartridge cover 7 cooperates the detent disk 51 to clamp the valve core seal ring 8.The spool connects
Spindle 5 is also provided with seal groove 9, and is accordingly equipped with sealing ring 8 on the seal groove 9.
Working principle of the utility model is:
When the water inlet 13 is connected to water source, water flows through water inlet 13 and flows into the valve core channel 4, in the effect of hydraulic pressure
Under, hydraulic pressure pressure can generate downward pressure to the spool connecting shaft 5, make the reset being in contact with the spool connecting shaft 5
Spring 31 is compressed, and then moves down the spool connecting shaft 5, therefore hydraulic pressure is bigger, and the spool connecting shaft 5 moves down
Distance it is bigger；It is connect accordingly, due to the cartridge cover 7 with the spool connecting shaft 5, the pre-determined distance can subtract therewith
It is small, so that the flowing water area of the water passage 4 is become smaller, finally reduce the water flow flowed into the valve chamber 6, and then reduces water
Pressure.Similarly, when the hydraulic pressure that water inlet 13 flows into the valve core channel 4 reduces, the reset spring 31 automatically resets, and increases institute
Pre-determined distance is stated, the flowing water area of the water passage 4 is made to become larger, finally increases the water flow flowed into the valve chamber 6, into
And improve hydraulic pressure.Therefore the utility model has the function of automatic stabilisation hydraulic pressure.
When water check valve will steadily in the long term when required hydraulic pressure, can adjusting screw rod 32 described in knob, to adjust the reset
The elasticity of spring 31.When the reset spring 31 is tighter, then the reset spring 31 is more difficult to be compressed, therefore by same
Water feeding pressure when, the reduction amount of the pre-determined distance is fewer, and correspondingly water yield can become larger, water outlet hydraulic pressure increase.Similarly, institute
State that reset spring 31 is more loose, the reduction amount of the pre-determined distance is bigger, and correspondingly water yield can become smaller, and water outlet hydraulic pressure reduces.
When needing that the water outlet hydraulic pressure of water check valve is adjusted immediately, due to the switching spool axis 2 and the spool
Connector is in contact, and can be directly changed the size of the pre-determined distance, and then realize water directly by turn-knob handle 21 described in knob
Press the function of adjusting.
In addition when turn-knob uses up the turn-knob handle 21, i.e., the pre-determined distance that is equipped between the described cartridge cover 7 and valve core channel 4
When being zero, the water passage is closed, and the water flow for obstructing the water inlet 13 enters in the valve chamber 6, finally realizes water check valve
Closing.
It is adjusted in conclusion the hydraulic pressure adjusting of the utility model can be divided into simple adjust in real time with normality hydraulic pressure, works as needs
It is daily when stablizing a certain hydraulic pressure, can be by adjusting screw rod 32 described in turn-knob, the elasticity for adjusting the reset spring 31 is compressed
Amount stablizes hydraulic pressure to obtain the normality；
When needing that hydraulic pressure is adjusted immediately, can by turn-knob handle 21 described in turn-knob, manually control cartridge cover 7 with
The pre-determined distance size of the valve core channel 4 is adjusted water outlet hydraulic pressure, realizes quickly adjustment hydraulic pressure and dual regulation hydraulic pressure
Effect.
When needing to shut down water check valve, can switching spool axis 2 described in turn-knob, so that the switching spool axis 2 is depressed the valve
Core cap 7 finally makes the cartridge cover 7 seal the valve core channel 4, realizes the effect for closing water check valve.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
