Abstract
The utility model provides a pressure vacuum release valve. The pressure vacuum release valve comprises a shell body and a valve seat, wherein the valve seat is arranged on the shell body, a guide rod is arranged on the valve seat, a nut is arranged at the top end of the guide rod, a guide rod valve seat is arranged at the lower end of the nut, a weight plate is arranged on the guide rod, a membrane is arranged between the guide rod and the valve seat, and trays are arranged on the two sides of the valve seat. The pressure vacuum release valve has the advantages that the pressure vacuum release valve is designed to be in a fully-opened type, the instant whole-course jumping performance is achieved, a breather valve can be completely opened when the overpressure reaches 10%, the unique sealing design is achieved, work efficiency is ensured, and safety is improved.
Description
Technical field
The utility model relates to inhalation valve field, relates in particular to a kind of pressure vacuum bleeder valve.
Background technique
Present inhalation valve flap Lift and external and internal pressure are poor not linear; when draught head is lower, can not reach the degree of opening completely; fail to reach specified maximum pump discharge; affected working efficiency; and the sealing effect of inhalation valve is not very desirable; often have and reveal generation, this also can exert an influence to the stability of inhalation valve.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of pressure vacuum bleeder valve is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A pressure vacuum bleeder valve, comprises housing and valve seat, is provided with valve seat on housing, is provided with guide rod on valve seat, and guide rod top is provided with nut, and nut lower end is provided with guide rod valve seat.
On further described guide rod, be provided with weight plate, between guide rod and valve seat, be provided with diaphragm, valve seat both sides are provided with pallet.
Further, diaphragm is fep film sheet.
The utlity model has following beneficial effect:
Pressure vacuum bleeder valve of the present utility model, valve disc and fep film sheet form air cushion, make sealing greatly improve effect remarkable, there is omnidistance take-off performance of moment, when superpressure reaches 10%, just can open inhalation valve completely, unique Seal Design, both guarantee working efficiency, improved again Security.
Accompanying drawing explanation
Fig. 1 is bleeder valve schematic diagram provided by the utility model.

6: diaphragm 7: pallet 8: valve seat
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of mode of execution of the present utility model, consult Fig. 1, a kind of pressure vacuum bleeder valve, comprise housing 1 and valve seat 8, on housing 1, be provided with valve seat 8, on valve seat 8, be provided with guide rod 4, guide rod 4 tops are provided with nut 2, and nut 2 lower ends are provided with guide rod valve seat 3.
On further described guide rod 4, be provided with weight plate 5, between guide rod 4 and valve seat 8, be provided with diaphragm 6, valve seat 8 both sides are provided with pallet 7.
Valve disc and fep film sheet form air cushion, make sealing greatly improve effect remarkable, when pressure is only lower than 10% of tank designs pressure, only need 10% superpressure, the flap that guide rod 4 and weight plate 5 combine just can moment whole process takeoff, reach specified maximum pump discharge.Low leakage valve disc is when 90% setting pressure, and valve seat and valve disc seepage are no more than 1SCFH. and contribute to reach namely said maximum unlatching value of 1/4 Flow diameter at the rear valve disc Lift of superpressure 10%, have so both guaranteed working efficiency, have improved again Security.
In sum; the utility model is only illustrated pressure vacuum bleeder valve embodiment; but the utility model is not limited to this; it will be appreciated by those skilled in the art that in the situation that do not depart from the protection domain that claims of the present utility model record and can change arbitrarily and revise.
