Abstract
The utility model relates to a telescopic fast gas pipe joint with a one-way valve, which is mainly composed of a joint pipe, a joint seat, a movable connection pipe, a one-way valve, a sheath and an outer sleeve. The big end of the joint pipe is arranged in the inner hole in the end part of the joint seat. The inner cavity of the joint seat is provided with a reverse stopping one-way valve composed of a valve core and a compression spring. The other end of the compression spring is supported by the bottom of the movable connection pipe which is sealed and arranged in the inner hole of the joint seat. The movable connection pipe is limited by a steel ball and has an upper position and a lower position. The upper part of the joint seat is sheathed with the sheath, the intermediate section is sheathed with the outer sleeve, and the compression spring is arranged between the sheath and the joint seat. The utility model realizes fast connection with gas pipe joints and has the advantages of good sealing performance, high durability and safe use.
Description
The utility model relates to the valve of gas pipeline accessory, specifically a kind of telescopic combustion gas quick coupling that one-way valve is arranged.
China's natural gas reserves are abundant, and along with the economic construction development, gas production is increasing, and it extensively replaces fire coal, oil to be used for industry, automobile as a kind of clean energy resource, and in the heating field and the cooking field enter family.The product that present application rock gas is the energy has also just been developed sub-fraction, in the today of being becoming tight electric power, coal, petroleum-based energy day, the use that enlarges this cleaning of rock gas, the cheap energy has far-reaching social benefit and economic benefit, and this just at first needs to develop new natural gas pipe accessory.The gas kitchen pipe joint of Xiao Shouing has following shortcoming in the market: the one, can not connect fast; The 2nd, sealability is bad; The 3rd, durable in use inadequately, working life is short.Therefore be badly in need of improving.
The purpose of this utility model provides a kind of improved telescopic combustion gas quick coupling that one-way valve is arranged.It can be connected fast with the gas pipeline joint, and good seal performance is durable in use, safe in utilization.
The purpose of this utility model is achieved in that
A kind of telescopic combustion gas quick coupling that one-way valve is arranged, it is characterized in that: it mainly is made up of adaptor tube, connection block, movable adapter, one-way valve, sheath and overcoat;
Adaptor tube is the stepped shaft hollow tubular, its small end cylindrical has overhead kick shape ring grain, its big end cylindrical has the annular groove of dress " O " RunddichtringO, the valve port that its big end endoporus is taper, the big end of this adaptor tube is contained in the end endoporus of connection block, the non-return one-way valve of being made up of spool and pressure spring is housed in this connection block inner chamber, the end cylindrical of this spool has the valve port of adorning " O " RunddichtringO and adaptor tube in the annular groove to match, this spool rear end conflict pressure spring also keeps normal closed state under this spring action, this spring is held in addition by a hollow movable bottom supporting of taking over, this activity is taken over the seal ring sealing and is contained in the endoporus of connection block, spacing and on having by three steel balls that are inlaid in the circumference in equal parts in the connection block hole wall, following two positions, the top of described connection block is set with sheath, the middle part is set with overcoat, and a pressure spring is housed between the terrace outside sheath bottom and connection block.
Described adaptor tube, movable material of taking over are brass, and the material of described connection block, spool, sheath and overcoat is heat-resisting nylon or polyoxymethylene, and the material of described spring is a Stainless Steel Wire, and the material of described seal ring is a chlorohydrin rubber.
The utility model has following actively useful effect:
1. be provided with the activity of being supported by spring in this pipe joint and take over, it is spacing and upper and lower two telescopic locations are arranged by being contained in steel ball in the connection block hole wall, during withdrawal connecting tube is locked, and can realize being connected with the quick of gas pipeline joint.
2. be provided with non-return one-way valve in the suction tude of this pipe joint, can prevent fuel gas return-flow, thus safe in utilization.
3. the junction plane of this tube joint assembly is provided with a plurality of seal rings, so good seal performance, and long-term the use can not leaked combustion gas yet.
4. the material of each assembly of this pipe joint is selected rationally, and fire retardancy is good, and is durable in use, and anti-collapsing force is strong, and is safe and reliable, long service life.
