Abstract
The utility model discloses a mechanical automatic exhaust valve, which comprises a valve body, a valve seat, a valve core, a spring and an adjusting screw, wherein the valve seat consists of an upper part and a lower part; the inner diameter of the upper part is less than that of the lower part; the valve core is cylindrical, is located in the lower part of the valve seat ns is in clearance fit with the valve seat; the length of the valve core is less than the depth of the lower part of the valve seat, so that the valve core is capable of vertically sliding on the lower part of the valve seat, and moreover, when the upper end face of the valve core is contacted with the upper part of the valve seat, the lower end face of the upper part of the valve seat can be closed; the spring is located in the upper part of the valve seat; the upper end of the spring is connected with the valve seat; and the lower end of the spring is connected with the valve core. The mechanical automatic exhaust valve disclosed by the utility model is simple in structure; fallback pressure can be adjusted by using the spring so as to adapt to working conditions with different inlet pressure; and after the mechanical automatic exhaust valve is adjusted, manual operation at regular time is not needed, i.e. the mechanical automatic exhaust valve is safe and labor-saving.
Description
Technical field
The utility model relates to a kind of outlet valve, relates in particular to a kind of hydraulic diaphragm pump and uses the mechanical type automatic control pressure vent.
Background technique
One of important auxiliary equipment of outlet valve diaphragm pump is directly connected to the using effect of pump.The conventional type outlet valve mainly contains ball-valve type and cone valve type, and ball-valve structure is simple, falls after rise by deadweight; Cone valve type falls after rise by deadweight and spring force, and these two kinds of structures are to all very bad grasp of the size of spillway discharge, and actual conditions are all can only manually-operable, waste time and energy, and dangerous.
This patent proposes a kind of mechanical type automatic control pressure vent, and falling pressure after rise can regulate with spring, adapts to different inlet pressure operating modes, after once mixing up, and regularly manual operation, safety saves trouble.
The model utility content
To the above-mentioned deficiency that existing technology exists, the purpose of the utility model just is to provide a kind of falling pressure to regulate with spring, the mechanical type automatic control pressure vent that safety saves trouble.
To achieve these goals; The technological scheme that the utility model adopts is such: a kind of mechanical type automatic control pressure vent; Comprise valve body, valve seat, spool, spring and adjusting screw, said valve seat is made up of two-part up and down, and the top internal diameter is less than the bottom internal diameter; Said spool be column and be positioned at the valve seat bottom and with the valve seat Spielpassung; The length of this spool is less than the degree of depth of valve seat bottom; Make spool to slide up and down, and when the spool upper-end surface contacts with valve seat top, can lower end surface, valve seat top be sealed in the valve seat bottom; Said spring is positioned at valve seat top, and its upper end links to each other with valve seat, and the lower end links to each other with spool.
Further, at spool outer wall being axially arranged with several and running through the up and down groove at two ends of spool along spool.
When the hydraulic diaphragm pump work, spool opens and closes with pump synchronously, and when air-breathing, spool is in the top of valve seat bottom, and gas accumulates in the spool bottom; During exhaust, spool is in the bottom of valve seat bottom, and gas upwards overflows through the groove on the spool outer wall, realizes automatic vent.
Compared with prior art, the advantage of the utility model is: simple in structure, falling pressure after rise can regulate with spring, adapts to different inlet pressure operating modes, utilize adjusting screw once to mix up after, regularly manual operation, safety saves trouble.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
Embodiment: referring to Fig. 1, a kind of mechanical type automatic control pressure vent comprises valve body 1, valve seat 2, spool 3, spring 4 and adjusting screw 5, and said valve seat 2 is made up of two-part up and down, and the top internal diameter is less than the bottom internal diameter; Said spool 3 be column and be positioned at valve seat 2 bottoms and with valve seat 2 Spielpassung; The length of this spool 3 is less than the degree of depth of valve seat 2 bottoms; Make spool 3 to slide up and down, and when spool 3 upper-end surfaces contact with valve seat 2 tops, can lower end surface, valve seat 2 top be sealed in valve seat 2 bottoms; Said spring 4 is positioned at valve seat 2 tops, and its upper end links to each other with valve seat 2, and the lower end links to each other with spool 3.At spool 3 outer walls being axially arranged with several and running through the up and down groove at two ends of spool along spool.
When the hydraulic diaphragm pump work, spool opens and closes with pump synchronously, and when air-breathing, spool is in the top of valve seat bottom, and gas accumulates in the spool bottom; During exhaust, spool is in the bottom of valve seat bottom, and gas upwards overflows through the groove on the spool outer wall, realizes automatic vent.
The utility model is simple in structure, and falling pressure after rise can regulate with spring, adapts to different inlet pressure operating modes, utilize adjusting screw once to mix up after, regularly manual operation, safety saves trouble.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
Claims (2)
1. a mechanical type automatic control pressure vent comprises valve body, valve seat, spool, spring and adjusting screw, it is characterized in that: said valve seat is made up of two-part up and down, and the top internal diameter is less than the bottom internal diameter; Said spool be column and be positioned at the valve seat bottom and with the valve seat Spielpassung; The length of this spool is less than the degree of depth of valve seat bottom; Make spool to slide up and down, and when the spool upper-end surface contacts with valve seat top, can lower end surface, valve seat top be sealed in the valve seat bottom; Said spring is positioned at valve seat top, and its upper end links to each other with valve seat, and the lower end links to each other with spool.
