Description
Technical field:
The present invention relates to a kind of link, specifically is a kind of device of hose coupling.
Background technique:
At present; The hose coupling device is widely used in civilian and industrial; Be used to carry liquids and gases; The hose coupling device of being sold on the market exists easy leakage, flexible pipe sealed department after using repeatedly, to damage easily always, and the requirement for the hose coupling device is strict with regard to more when some special use especially.Along with the continuous development of science and technology, a collection of hose coupling that has scientific and technological content has appearred.
Chinese patent 200520039193.8 hose coupling devices; It is joint employing fastener overhead structure with flexible pipe; The installation head that only needs during installation flexible pipe directly to be inserted hose coupling partly gets final product; When dismounting, also only need the installation head fastener of installation head part is inwardly pinned, just can flexible pipe be extracted from hose coupling together with installation head easily, easy for installation.But this kind hose coupling device mainly is suitable for the joint of analogous cable line and installs.
Chinese patent 200420082175.3 hose couplings comprise connection block, and this connection block has entrance point and outlet end, and entrance point is provided with the honeycomb duct that connects flexible pipe, and the caliber of this honeycomb duct is less than entrance point; Be equipped with the pipe collar that compresses flexible pipe on the honeycomb duct, the external diameter of this lock ring is less than or equal to the external diameter of entrance point; The entrance point lock ring nut that has been threaded, this lock ring nut inner chamber have the press section of extruding pipe collar.This device be with hose proof after on the entrance point, thereby reach purpose of connecting through fixing entrance point.But this device have a shortcoming be exactly hose proof behind entrance point owing to be conveying gas, be easy to because the phenomenon that the pressure of gas exists running-on to leak gas.
And when some special industries, particularly strict for the sealing and the requirement of safety and sanitary property of hose coupling device, this point does not also have suitable product to satisfy the demand at present at home.
Summary of the invention:
The present invention wants the technical solution problem to be to provide a kind of particular surroundings to be suitable for the good air hose joint device for breathe of pipe joint sealingly secure property.
The present invention for the technological scheme that the technical solution problem adopts is:
A kind of air hose joint device for breathe mainly is made up of joint shell, valve butt joint and air valve, connects through flexible pipe between air valve and the joint shell, and the safety cover of flexibility is installed at the said flexible pipe and the jointing of air valve, joint shell.
Said flexible pipe is made up of flame-retardant materials.
One end buckle of joint on the said joint shell and valve butt joint is connected, and connects air feeder at the said valve butt joint the other end.
The one end connector connection of said air valve receives device of air, and the other end connects flexible pipe.
Said joint shell comprises a joint from left to right successively, laterally runs through in the joint, vertically has a hole and communicates with the hole of laterally running through, and have family tower spring and switch are installed in said vertical hole; Also comprise a switch card, zero RunddichtringO, valve core, zero RunddichtringO, pin, zero RunddichtringO, vent valve, chamber tower spring, safety cover and hose coupling composition, hose coupling is with flexible pipe outward; In the joint of said joint shell, also be provided with a circle spill draw-in groove.
Said valve butt joint comprises that second joint of valve butt joint, centering card, guide rod, spring, zero RunddichtringO and valve butt joint constitutes, and the top of said valve butt joint is provided with buckle and is connected fixing with the interior spill draw-in groove of said joint shell.
Said air valve comprises an air valve joint shell, laterally has penetration hole in said joint shell and communicates with the longitudinal switch hole that the joint shell left end has, and chamber tower spring and switch are housed in the switch hole; Also comprise the switch card, spring, valve core, envelope gas shell, zero RunddichtringO, the envelope gas heart, zero RunddichtringO, spring and the hose coupling that are installed in the joint shell right-hand member successively, outside the air valve joint shell connect, hose coupling was with flexible pipe outward.
Working principle of the present invention is between the joint of the joint and the joint shell that are enclosed within air valve of the two ends with flexible pipe; Between air valve and joint shell, form path; The valve butt joint is entrapped in the joint shell; Gas passes in joint shell, flexible pipe and the air valve successively from the valve butt joint, is communicated to receive on the device of air.Wherein flexible pipe is processed spiral and is twined, and satisfies in the varying environment the requirement of length, especially in the laboratory, satisfies the scope of three-dimensional activity.
The beneficial effect that the present invention produces is that the hose coupling device is reasonable in design reliable, good airproof performance, and anti-flexibility is strong; Butt joint and convenient disassembly between valve butt joint and the joint shell; Even when the valve butt joint is pulled down, the automatic sealing and fixing of centering card meeting in the valve butt joint keeps good sealing; Extraneous gas can be to not causing gaseous contamination, can well protect health and the Security that receives device of air in the valve channel like this.Whole hose coupling device has just kept high-seal in the pipeline and hygienic characteristic when design, when cleaning the outside, pipe interior is had no influence.And flexible pipe is made up of the material of flame retarding, has good fire resistance, can satisfy the demand of special industry.
