Abstract
The utility model relates to the high pressure cylinder and binding fence of a pressure vessel; a protective cap arranged at the outside of the valve body is fixed on the bottle body through a bolt; a side port is arranged at one side of the protective cap next to a pressure tap, and is used for the abutting of the pressure gauge and the interface; the top of the protective cap is provided with a top opening for the opening of the valve body by inserting a wrench; the abutting pipe head of the valve body and the pressure gauge is in spherical surface. One end of the binding fence can be fixed on the abutting pipe of the pressure gauge, and is stopped by a block; the other end of the binding fence is screwed with a ball head thimble; the ball head arranged on the ball head thimble is arranged in the cavity arranged on the cap plate of a thimble ball head; the cap plate of the thimble ball head is contacted with the protective cap during use. The high pressure gas cylinder provided by the utility model adopts the new style protective cap and a safety valve, and the valve body of the high pressure gas cylinder is protected.
Description
Technical field
The utility model relates to pressurized container, particularly pressure cylinder and pressure gauge is fixed on Zha Lan on the gas cylinder.
Background technique
At present, there is following shortcoming in design in the valve body on the common gas cylinder.The first, the valve body peripheral hardware on gas cylinder bottle top is in respect of protective cap.This protective cap is enclosed within on the valve body, and is connected on the bottle threadably.The shortcoming of this design is: protective cap need be screwed off when the operator uses, could be connected and open valve body with pressure gauge then.After using, the operator often forgets or unwillingly protective cap is put again.Like this, the consequence that causes is outside valve body usually is exposed to, and when meeting accident collision, causes valve body to be fractureed, and whole gas cylinder is scrapped.The second, on valve body, also be provided with a safety valve usually, still, existing safety valve structure is simple.Mainly be provided with a pressure plate, when pressure of the inside of a bottle surpassed safety value, pressure plate was broken through, and plays the effect of safety valve.Sometimes, but because of the unstable of the bearing capacity of pressure plate or change, make that pressure plate was also broken through when pressure did not surpass safety value.Its consequence is that whole bottle gas has all been wasted.The 3rd, valve body and pressure gauge are by being threaded.And pressure gauge is to need often dismounting.The normal problem that occurs is that the screw thread screw thread is damaged in the use, and pressure gauge can't be connected with valve seal.
On the other hand, existing acetylene cylinder has adopted a kind of special mode.Its valve body is not to pass through screw thread with manometric the connection.The tube head that its pressure gauge docks with valve body is flat-headed, docks with the corresponding plane interface of valve body, and fixes by Zha Lan.
Summary of the invention
The purpose of this utility model be by to the valve body protective cap, with the improvement of manometric interface and safety valve, the valve body on the protection gas cylinder prolongs working life of bomb.
The gas cylinder that the utility model provides; wherein the outer protective cap of valve body is by being bolted on the bottle; side at protective cap depended on pressure table interface has the side mouth that docks with interface for pressure gauge; have the top mouth of opening valve body for the insertion spanner at the top of protective cap, the tube head that valve body docks with pressure gauge is sphere.
The end of Zha Lan can be fixed on the manometric butt tube, and by the block stop bit; The other end of the Zha Lan bulb thimble that has been threaded, the bulb on it place in the cavity on the thimble bulb cover plate, and thimble bulb cover plate contacts with protective cap in use.
Further improving is that traditional tinsel safety valve is improved to automatic dropping valve.Specifically be inserting spring in original valve pipe, the front end of spring is preceding valve seat, and preceding valve seat front end is cone and stuffing box packing, and the rear end of spring is a rear valve base, and the valve pipe is with the safety valve cap outward.
Further improving is to be provided with ball between safety bonnet and rear valve base.Bond together to prevent corrosion between safety valve cap and valve pipe.
Describe structure of the present utility model and beneficial effect in detail below in conjunction with embodiment.
Fig. 1 is the utility model embodiment's a schematic perspective view;
Fig. 2 be the utility model embodiment plan view;
Fig. 3 is the utility model embodiment's a partial sectional view.
Referring to Fig. 1,2,3, valve body 1 outer protective cap 2 is to be fixed on the bottle 4 by bolt 3, side at protective cap 2 depended on pressure table 5 interfaces has the side mouth 6 that docks with interface for pressure gauge 5, has at the top of protective cap 2 for inserting spanner and opens the top mouth 7 of valve body; The interface 27 that valve body 1 docks with pressure gauge 5 is sphere shape.
An end of pricking hurdle 8 can be fixed on the butt tube 19 of pressure gauge 5,, and by block 9 stop bits; The other end of the pricking hurdle 8 bulb thimble 10 that has been threaded, the bulb 11 on it place in the cavity on the thimble bulb cover plate 12, and thimble bulb cover plate 12 contacts with protective cap 2.Inserting spring 14 in original valve pipe 13, the front end of spring 14 are preceding valve seats 15, and preceding valve seat 15 front ends are stuffing box packing 16, and the rear end of spring 14 is rear valve bases 17, are with safety valve cap 18 outside the valve pipe 13, are provided with ball 20 between safe bonnet 18 and the rear valve base 17.Be equipped with overflow hole 21,22 on rear valve base 17 and the safe bonnet 18.For fixing safe bonnet 18, on valve pipe 13, also be provided with spring pad 23, nut 24 and jam nut 25.
By adjusting the relative position of safe bonnet 18 and valve pipe 13, the size of decision safety valve threshold values.When the pressure in the gas cylinder 4 surpassed safety value, by jack-up, pressure spring 14, gas discharged from overflow hole 21,22 with preceding valve seat 15 in stuffing box packing 16.After pressure reduced, spring 14 made preceding valve seat 15 returns, and stuffing box packing 16 seals valve body 1 with preceding valve seat 15 conical sections.
When needs use gas cylinder; earlier pressure gauge 5 tube heads are inserted valve body interface 27, pricking hurdle 8, to be enclosed within protective cap outer 2, and thimble bulb cover plate 12 is withstood on the protective cap 2; adjust the position of bulb thimble 10, make thimble 10 and pressure gauge 5 butt tubes 19 on a horizontal line.Tighten bulb thimble 10 with combination wrench 26, bundle hurdle 8 is fixedly connected on pressure gauge 5 on the valve body 1.Make a call to 26 from protective cap 2 upper ends with combination wrench again and open valve body 1, can use gas cylinder.
As can be seen, the gas cylinder that the utility model provides makes the valve body of gas cylinder be protected owing to adopted novel protective cap and safety valve from above-mentioned explanation, and matching used Zha Lan uses more convenient, thereby has reduced cost of production.
