Abstract
The utility model relates to a multifunctional control valve of a water pump, which includes a valve body, a valve clack, a valve rod, a return spring, a diaphragm, diaphragm clamp plates, a locknut component and a valve cap. A diaphragm control cabin is formed by the diaphragm and the upper and the lower diaphragm clamp plates; the return spring is arranged between the diaphragm control cabin and the valve cap; and the valve rod comprises two parts with different diameters, wherein the top end of the upper part of the valve rod is fixed in a positioning hole of the valve cap, the middle part of the valve rod is fixedly connected with the upper diaphragm clamp plate through the locknut, and the lower part is fixedly connected with the valve clack. The utility model avoids springs at the upper sides of a core rod and the valve clack, thereby reducing the pressure of the core rod to the valve rod, decreasing to the maximum extent the unloading loss of media overflow, and improving the work efficiency of the control valve.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of multifunctional water pump control valve.
Background technique
Existing multifunctional water pump control valve is made up of parts such as valve body, flap, valve rod, Returnning spring, spring, valve rod positioning device, diaphragm, diaphragm clamping plate, lock nut assembly and valve gaps, diaphragm and upper and lower diaphragm clamping plate constitute the diaphragm control room, between flap upper end and diaphragm control room, be provided with spring, spring housing is located at the valve rod outside, between diaphragm control room and valve gap, be provided with Returnning spring, link to each other by mandrel between valve rod and the diaphragm.Behind starting mode of pump, valve inlet hydraulic pressure raises, press water produces the power that flap is opened that promotes on the one hand, on the other hand by outer connecting tube of valve body, enter the diaphragm control room, but owing to be provided with spring between flap upper end and diaphragm control room, mandrel can be given valve rod pressure, the loss of unloading in the time of can increasing the medium overcurrent again simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of more reasonable structure, multifunctional water pump control valve that working efficiency is higher are provided.
For achieving the above object, the utility model adopts a kind of multifunctional water pump control valve, comprise valve body, flap, valve rod, Returnning spring, diaphragm, diaphragm clamping plate, lock nut assembly and valve gap, diaphragm and upper and lower diaphragm clamping plate constitute the diaphragm control room, between diaphragm control room and valve gap, be provided with Returnning spring, valve rod is made up of different two sections of diameter up and down, its epimere part topmost is fixed in the positioning hole on the valve gap, fixedly connected with the upper diaphragm clamping plate by locking nut in the valve rod stage casing, valve rod hypomere part is fixedlyed connected with flap.
The utility model further is set to be arranged with in the valve rod lower semisection part outside socket of hollow, and the upper/lower terminal of socket is separately fixed on flap and the following diaphragm clamping plate.
The utility model has been cancelled the spring of core bar and flap upside, has reduced the pressure of core bar to valve rod, the loss of unloading when having reduced the medium overcurrent to greatest extent, the working efficiency of raising control valve.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of multifunctional water pump control valve, comprise valve body 1, flap 2, valve rod 3, Returnning spring 4, diaphragm 5, on, following diaphragm clamping plate (6,7), lock nut assembly and valve gap 9, diaphragm 5 and last, following diaphragm clamping plate (6,7) constitute the diaphragm control room, between diaphragm control room and valve gap 9, be provided with Returnning spring 10, valve rod 3 is made up of different two sections of diameter up and down, its epimere part 31 topmost is fixed in the positioning hole 91 on the valve gap 9, fixedly connected with upper diaphragm clamping plate 6 by locking nut 10 in valve rod stage casing 32, valve rod hypomere part 33 is fixedlyed connected with flap 2.Be arranged with the socket 8 of hollow in the valve rod lower semisection 33 parts outside, the upper/lower terminal of socket 8 is separately fixed on flap 2 and the following diaphragm clamping plate 7.
The utility model has been cancelled the spring of core bar and flap 2 upsides, has reduced the pressure of core bar to valve rod 3, the loss of unloading when having reduced the medium overcurrent to greatest extent, the working efficiency of raising control valve.
