Abstract

The utility model discloses a safety relief valve and belongs to the technical field of hydraulic membrane measuring pump elements. The relief valve comprises a valve body, a valve seat fitted with the bottom of the valve body, an axial through-hole and a radical through-hole arranged on the valve seat, a safety valve core arranged inside the valve body chamber, a guiding rod sleeved on the safety valve core, a spring seat and the corresponding spring arranged on the guiding rod, a regulating nut arranged on the top of the valve body, and a relief valve core, a relief valve spring and a relief valve ball fitted in the safety valve core chamber. The utility model has reasonable and sample structure and functions for the safety valve and the relief valve, therefore the valve can simplify structure of hydraulic membrane measuring pump, reduce volume and production cost, and improve control performance of the safety valve.

Description

Gassy Relief Valve
Technical field
The utility model relates to the Hydraulic Diaphragm Metering Pump parts, is specifically related to Gassy Relief Valve.
Background technique
In the Hydraulic Diaphragm Metering Pump of present numerous domestic, safety valve, bleed valve are to guarantee one of requisite constituent elements of Hydraulic Diaphragm Metering Pump trouble free service.When hydraulic pressure cavity pressure surpassed the authorized pressure of regulation, safety valve can be opened rapidly, and discharge section hydraulic oil plays the effect of protection whole system; And bleed valve has the gas of bringing hydraulic pressure cavity when plunger worked into and discharges cavity.Present safety valve, bleed valve are valve independently respectively, make the Hydraulic Diaphragm Metering Pump complex structure, the cost of production height.
The model utility content
For overcoming problems of the prior art, the utility model aims to provide a kind of safety discharging air valve that safety valve, bleed valve function are united two into one.
Described Gassy Relief Valve, comprise valve body, the cooperation of valve body bottom is provided with valve seat, valve seat is provided with axial hole, radial direction through hole respectively, be provided with safe spool in the valve body chamber, be arranged with guide rod on the safe spool, this guide rod is provided with spring seat and corresponding safety spring, the valve body top is provided with adjusting nut, is equipped with venting spool, venting valve spring and valve ball in the safe spool chamber.
Described Gassy Relief Valve, its venting spool below is provided with gap spacer and back-up ring.
Described Gassy Relief Valve, the upper-end surface of its valve body is provided with locking nut.
Described Gassy Relief Valve, its adjusting nut top are provided with and show window.
Described Gassy Relief Valve, structural design is ingenious, and structure is simplified, and safety valve, bleed valve function are united two into one, and has simplified the structure of Hydraulic Diaphragm Metering Pump greatly, has dwindled volume, has reduced cost of production, has improved the control performance of safety valve simultaneously.
Description of drawings
Fig. 1 is vertical sectional structure schematic representation of the utility model one preferred embodiment.
Embodiment
Combination now describes a preferred embodiment of the present utility model in detail.
Gassy Relief Valve shown in Figure 1, comprise valve body 5, valve body 5 outsides are equipped with O RunddichtringO 12, the cooperation of valve body 5 bottoms is provided with valve seat 1, valve seat 1 bottom is provided with down O RunddichtringO 16, valve seat 1 is provided with axial hole 18 respectively, radial direction through hole 15, be provided with safe spool 2 in valve body 5 chambeies, be arranged with guide rod 4 on the safe spool 2, be provided with ball pad 3 between guide rod 4 and the safe spool 2, this guide rod 4 is provided with spring seat 9 and corresponding safety spring 11, the upper-end surface of valve body 5 is provided with locking nut 6, valve body 5 tops are provided with adjusting nut 7, are used to regulate the compression strength of safety spring 11, and adjusting nut 7 tops are provided with and show window 8, be used to check the inner case of Gassy Relief Valve, be equipped with venting spool 14 in safe spool 2 chambeies, venting valve spring 13 and valve ball 10, venting spool 14 belows are provided with gap spacer 19 and back-up ring 17, and the Lift of venting spool 14 can be regulated by gap spacer 17 and back-up ring 19.
The working procedure of described Gassy Relief Valve: when the Hydraulic Diaphragm Metering Pump system oil pressure surpasses the impacting force of the safety spring 11 on the safe spool 2, fluid passes through axial hole 18 with safe spool 2 jack-up, thereby, fluid can flow out through radial direction through hole 15, the Load Relief System oil pressure plays the effect of protection whole system; Because the oil pressure of Hydraulic Diaphragm Metering Pump produces pulsation with the plunger to-and-fro motion, in plunger imbibition process, venting spool 14 is deflated valve spring 13 and pushes open, at this moment, exist the gas in the oil pocket to discharge, and back down outside valve ball 10 excavationg pumps along the clearance gap that the venting spool is pushed; And when the plunger discharge opeing, because of oil pocket pressure increases gradually, venting spool 14 compresses venting valve spring 13, closes exhaust.
