Abstract
The utility model relates to a gas pressure regulator is in it admits air the connecting pipe, and sport mouth independent setting has guaranteed perpendicularity and the interval of sport mouth with the piston packaging face, and the long -pending piston packaging every detail that is less than of sport mouth tapering point every detail is amassed, the whole size of sport mouth is unified, and fixed back is unified with the piston packaging interplanar distance, has two sealed settings, and sealing performance is good, and the assembly degree of difficulty reduces, and performance control is easy.
Description
Technical field
The utility model relates to a kind of gas pressure regulator, governor, especially a kind of LPG (liquefied petroleum gas) pressure regulator.
Background technique
In prior art, usual LPG (liquefied petroleum gas) pressure regulator, jet nozzle and air input joint are disjunctors, with lower valve body with being threaded, if lower valve body screw thread merit is shaped with the depth, the spacing in jet nozzle and piston seal face is then caused to differ greatly, thus cause LPG (liquefied petroleum gas) pressure regulator closedown air pressure too low or too high, if merit screw thread and lower valve body out of plumb, air input joint also deflection thereupon after being connected with lower valve body, jet nozzle and piston seal face out of plumb, after causing ventilating, air-flow is irregular, cause pressure governor unstable properties, the serious voltage stabilizing that also can cause was lost efficacy, affect use safety.
Model utility content
The utility model is for the deficiencies in the prior art, there is provided a kind of LPG (liquefied petroleum gas) pressure regulator, it is in inlet pipe connection, and jet nozzle is independently arranged, ensure that perpendicularity and the spacing in jet nozzle and piston seal face, thus after ensure that pressure governor ventilation, jet flow evenly, stable performance, voltage regulation result be good.
For realizing above technology, the utility model will adopt following technological scheme:
A kind of gas pressure regulator, governor: comprise two ends are respectively arranged with inlet pipe connection and the lower valve body of connecting tube of giving vent to anger is fixedly connected with lower valve body upper valve body and be arranged on the diaphragm between lower valve body and upper valve body, described diaphragm and be fixedly installed pallet, be provided with Compress Spring between pallet and upper valve body.
Independently be provided with jet nozzle in described inlet pipe connection, jet nozzle tapered end face area is less than piston seal face area.
Described jet nozzle is a multi-stage cylinder, and there is through hole centre, and the stage casing of jet nozzle and end are provided with seal ring and sealing gasket, are fixed in inlet pipe connection by jet nozzle with air input joint.
In described jet nozzle, polyformaldehyde material is made.
According to above technological scheme, following effect can be realized:
This stage casing with novel described jet nozzle and end are provided with seal ring and sealing gasket, thus substantially increase sealability, prevent Leakage Gas, improve safety in utilization.
Jet nozzle described in the utility model, by the hot injection forming of polyoxymethylene, improves the uniformity of stem bar spray overall dimensions, overcomes the defect that existing disjunctor jet nozzle and piston seal interplanar distance differ greatly, also reduce assembling difficulty simultaneously.

Fig. 3 is the sectional view of jet nozzle described in the utility model
Embodiment
The technical solution of the utility model is described in detail below with reference to accompanying drawing:
As shown in Figure 1, LPG (liquefied petroleum gas) pressure regulator described in the utility model, comprise the lower valve body 1 that two ends are respectively arranged with inlet pipe connection 7 and connecting tube 8 of giving vent to anger, the upper valve body 2 be fixedly connected with lower valve body 1 and the diaphragm 3 be arranged between lower valve body 1 and upper valve body 2, described diaphragm 3 is fixedly installed pallet 4, Compress Spring 5 is provided with between pallet 4 and upper valve body 2, jet nozzle 12 is independently provided with in described inlet pipe connection 7, be connected with inlet pipe connection 7 with air input joint 6, jet nozzle 12 is fixed in inlet pipe connection 7, the cone surface which area of described jet nozzle 12 outlet side is less than piston 9 sectional area.
Described jet nozzle 12 body is provided with seal ring step 121, sealing gasket step 122, and seal ring 13 is enclosed within 121 places, and sealing gasket 14 is enclosed within 122 places, improves sealing, enhance the Security of use after jet nozzle 12 is fixing with inlet pipe connection 7.
Described jet nozzle 12 body is provided with the concentricity that piston displacement guide pin bushing 123 further ensures jet nozzle and piston.
Described jet nozzle 12 is by the hot injection forming of polyoxymethylene, and overall dimensions uniformity is good, and assembling is rear and piston spacing dimension uniformity is higher.
Claims (4)
