Description
Technical Field
The utility model relates to a self priming pump technical field especially relates to an automatic bleed valve for self priming pump.
Background
The self-priming pump has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, stronger self-priming capability and the like, and is widely applied to various industries.
Self priming pump is when the start-up operation, and the pump is in from inhaling the state, and the water level in the pump chamber increases gradually, and along with the water level constantly increases, the air of water level upside in the pump chamber need in time discharge can normal operating in order to ensure self priming pump, consequently, can install the electronic bleed valve on the self priming pump usually and be used for exhausting when self priming pump start-up operation, but the electronic bleed valve is with higher costs and the fault rate is high under on-the-spot complicated operational environment.
SUMMERY OF THE UTILITY MODEL
To the above problem, the embodiment of the utility model provides an automatic bleed valve for self priming pump.
The utility model discloses an aspect of implementation provides an automatic bleed valve for self priming pump, including the valve body, be provided with the valve pocket in the valve body, the valve body top surface is the opening form, on the valve body with opening relative bottom surface on seted up with valve pocket intercommunication inlet port, the inlet port communicates with the pump chamber of self priming pump, in the valve chamber with the coaxial guide sleeve that is provided with of inlet port, slide in the guide sleeve and be provided with the valve plate, valve body opening side cover is equipped with the valve gap, be provided with the exhaust hole that communicates with the valve pocket relatively with the valve plate on the valve gap, the valve plate can be sealed by jack-up and exhaust hole under the hydraulic effect of pump chamber.
Compared with the prior art, the beneficial effects of the utility model reside in that: the weight of the valve plate is determined according to the exhaust pressure and the drainage pressure in the pump cavity, so that the gravity of the valve plate is larger than the jacking force generated by the exhaust pressure when the pump cavity exhausts air and smaller than the jacking force generated by the drainage pressure when the pump cavity exhausts water; therefore, when the self-priming pump is started to operate and is in a self-priming state, air on the upper side of the water level in the pump cavity is discharged by the automatic air discharge valve, and after the pump cavity is filled with water, the density of the water is higher than that of the air, so that the jacking force generated by the water is higher, the valve plate is jacked up to seal the exhaust hole, and the normal operation of the self-priming pump is realized in the self-priming process; the automatic air release valve has the advantages of simple integral structure, easy manufacture, low manufacture cost and low failure rate.
Optionally, the periphery of the guide sleeve is provided with support columns at intervals, and the support columns are fixed with the valve body.
Optionally, the valve plate comprises a guide post slidably disposed in the guide sleeve, and a sealing plate disposed at a top end of the guide post.
Optionally, the exhaust hole is a stepped hole with a gradually increasing aperture from bottom to top.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention. In the drawings:
fig. 1 is a schematic structural view of an automatic release valve for a self-priming pump according to an embodiment of the present invention.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Referring to fig. 1, the embodiment of the utility model provides a pair of an automatic bleed valve for self priming pump, including valve body 1, be provided with valve pocket 2 in the valve body, 1 top surface of valve body is the opening form, seted up on the valve body 1 with opening relative bottom surface on the side with the valve pocket 2 intercommunication inlet port 3, inlet port 3 communicates with the pump chamber of self priming pump, 2 internal and 3 coaxial guide sleeve 4 that are provided with of inlet port of valve pocket, it is provided with valve plate 5 to slide in the guide sleeve 4, 1 opening side cover of valve body is equipped with valve gap 6, be provided with the exhaust hole 7 that communicates with valve pocket 2 with valve plate 5 relatively on the valve gap 6, valve plate 5 can be sealed by jack-up and exhaust hole 7 under the hydraulic effect of pump chamber.
In the implementation, the support columns 8 are arranged at intervals on the periphery of the guide sleeve 4, and the support columns 8 are fixed with the valve body 1; the valve plate 5 is T-shaped in section and comprises a guide post arranged in the guide sleeve 4 in a sliding manner and a sealing plate arranged at the top end of the guide post; the exhaust hole 7 is a stepped hole with the diameter gradually increasing from bottom to top.
The weight of the valve plate 5 is determined according to the air pressure and the water pressure in the pump cavity, and specifically, the gravity of the valve plate 5 is larger than the jacking force generated by the exhaust pressure when the air is exhausted in the pump cavity and smaller than the jacking force generated by the drainage pressure when the water is drained in the pump cavity; therefore, when the self-priming pump is started and operated to be in a self-priming state, the valve plate 5 is located at the initial position A, air on the upper side of the water level in the pump cavity is discharged by the automatic air release valve, and after the pump cavity is filled with water, the density of the water is higher than that of the air, so that the jacking force generated by the water is higher, the valve plate 5 is jacked to be located at the working position B to be sealed with the exhaust hole 7, and the normal operation of the self-priming pump is realized in the self-priming process; the automatic air release valve has the advantages of simple integral structure, easy manufacture, low manufacture cost and low failure rate.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
