Abstract

The utility model relates to a valve for inflation and deflation for air cushion type objects, in particular to an inflator pump manual valve with a double-air pipe connector. The inflator pump manual valve comprises a valve body and a cover plate buckled with the valve body, wherein an air vent hole communicated with a connector is arranged in the valve body, a valve opening is controlled by an elastic resetting sliding seat controlled by a handle draw rod for opening and closing, the top end of a movable contact piece arranged at the front end of the sliding seat and a fixed contact piece of an air pump power line arranged at the front end of the cover plate form an electric switching device of the air pump, and an air inlet pipe connector and an air exhaust pipe connector which are communicated are arranged at the front end of the valve body. Since the air inlet pipe connector and the air exhaust pipe connector which are communicated are arranged at the front end of the valve body, a three-way pipe and a pipeline thereof in the prior art are omitted, the structure is simple, the production cost is reduced, the installation and the maintenance are convenient, the inflator pump manual valve is especially suitable for being installed in a narrow space, the angles of 0 degree, 90 degrees and 180 degrees are formed between the two air pipe connectors according to the installation position, thereby the application range is wider.

Gas-filled pump hand control valve with two gas-tpe fittings

Technical field

The utility model relates to the hand control valve that the air cushion type objects charges and discharge the gas-filled pump of gas.

Background technique

General inflatable packer is all controlled the startup of air pump and with the air pressure size of switch electromagnetic valve control air cushion shock-absorption air bag, is regulated human comfort with switch, is controlled by hand control valve usually.The annexation of existing hand control valve and air pump, air bag as shown in Figure 7, air pump 1 is by power connection 2 power supplies, its air supply pipe is connected to three-way union, two other gas-tpe fitting 5,6 of three-way union is communicated with hand control valve 4, air bag 3 respectively, hand control valve 4 has only an exhaust fitting, draw, push away the hand control valve handle, can control the gas that charges and discharge of the break-make of air pump power supply and air bag, the structure relative complex, pipeline is many, incompatible below automobile cushion for example, install in the small space, inconvenient maintenance, cost is also higher.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, compact, is easy to install and maintain.Lower-cost gas-filled pump hand control valve with two gas-tpe fittings.

A kind of gas-filled pump hand control valve of the utility model with two gas-tpe fittings, comprise valve body and the cover plate that fastens with it, have the vent hole that is communicated with joint in the valve body, elastic reset slide control valve bore by handle bar control opens and closes, be loaded on the movable touching plate top of slide front end and the electric switchgear of the air pump power line fixed touching plate formation air pump that is loaded on cover forward end, it is characterized in that the valve body front end is equipped with suction tude joint and the exhaust fitting that communicates.

Described suction tude joint and exhaust fitting are 0 °, 90 °, 180 ° settings.

Communicating of described suction tude joint and exhaust fitting is made of the duct of opening system in the valve body, and the two ends, duct are communicated with suction tude joint and exhaust fitting respectively.

The utility model is arranged on the valve body front end in the lump with suction tude joint and the exhaust fitting that communicates, the threeway and the pipeline thereof of prior art have been omitted, simple in structure, volume compact, cost of production reduces, and installation and maintenance are convenient, be particularly suitable in small space, installing, and can limit according to the mounting point, two gas-tpe fittings are arranged to 0 °, 90 °, 180 ° angles, adapt to wide.

Embodiment:

With reference to Fig. 1, Fig. 2 embodiment 1: valve body 2 fastens in opposite directions by screw and cover plate 3, have the vent hole 22 (valve opening) that is communicated with joint in the valve body 2, valve body 2 front ends are equipped with suction tude joint 7 and the exhaust fitting 8 that is communicated by valve body inner bore road 21, two joints be arranged in parallel, the suction tude joint is communicated with air pump, exhaust fitting is communicated with air cushion or air bag, and this two arbitrary joint can be set at suction tude joint or exhaust fitting arbitrarily according to needs are installed.Air valve handle 1 is tightened together by interior hexagonal tight fixed bolt and air valve pull bar 11, and air valve pull bar 11 tops are passed the center hole of valve body 2 and linked with air valve slide 4, and slide 4 is loaded in valve body 2 and cover plate 3 buckling bodies, and is slidingly matched with the valve body planar slot.Bench port is expanded in vent hole 22 lower ends of valve body, setting-in 0 shape seal ring 6 in mouthful.Valve body 2 respectively is shaped on relative arc surface pit with cover plate 3, and the rectangle fenestra of two arc surface pits and therebetween slide 4 is formed the cylindrical cavity volume of ccontaining helical spring 5.During inflation by lower air valve handle 1 (for making things convenient for manually-operable, handle up when usually hand control valve being installed), helical spring 5 is subjected to down pressure extrusion-deformation, air valve slide 4 is descending with handle 1, the movable touching plate top of slide and the air pump power line fixed touching plate 9 that is loaded on cover forward end constitute the electric switchgear of air pumps, movable touching plate contacts energising to lower slider and with the air valve power line fixed touching plate 9 that is embedded in cover plate 3, make air pump motor energising entry into service, the vent hole 22 on the valve body 2 is blocked in air valve slide upper-end surface simultaneously, valve cuts out, and the gas that pumps from air pump is through suction tude joint 7, duct 21, airbag aeration is given in exhaust fitting 8.When the external force effect disappearance that acts on the air valve handle 1, helical spring 5 actions on the slide 4 reset, and make slide reply original state, because vent hole 22 is still blocked in the slide upper-end surface, valve still is in closed condition.Air valve handle 1 is under the effect of pulling force during venting, the helical spring 5 that resets is subjected to external force extrusion-deformation upwards, slide 4 upwards slides, the axial notch 41 of slide upper-end surface is under the vent hole 22, sealing disappears, and the gas in the air bag carries out exhaust decompression by gas-tpe fitting 8 and air valve body vent hole 22.Release handle 1 when exhaust is finished, and external force disappears, and helical spring 5 actions that reset on the air valve slide 4 reset, and make air valve slide 4 reply original state, and vent hole 22 are blocked again with valve closure in air valve slide upper-end surface, finishes whole work period.

With reference to Fig. 3, Fig. 4 embodiment 2: structure is substantially the same manner as Example 1, and different is 90 ° of settings of two joints, and corresponding duct 21 levels make two joints are communicated with, certainly, and the unspecified angle that one of two joints can be on vertical surface.

With reference to Fig. 5, Fig. 6 embodiment 3: structure is substantially the same manner as Example 1, and different is, and two joints all are arranged on is 180 ° on the vertical surface.Certainly, two joints can arbitrary angle setting on vertical surface.
