Description
Technical field
The utility model is related to a kind of safety valve class technical field, especially novel straight knurling safety valve.
Background technology
Safety valve is the safety device of pressure piping, is typically mounted on closed system equipment or pipeline and protects system
System safety, when the pressure inside the equipment of closed system or pipeline is more than setting value, safety valve is automatically turned on and is released stress,
Ensure that the pressure medium in equipment or in pipeline in specified value, prevents safety accident, however, common safety valve is big
Mostly monoblock type, and it is complicated, and volume is larger, assembling trouble, adjustment and repair trouble, and spool is generally copper metal
Material, material cost is high, and fills rubber gasket in the lower end sealing surface of spool, but for a long time, rubber seal is lined with not
Rule abrasion, causes leakproofness bad；When air pressure exceeds set point, high pressure gas spool is open-top, and high pressure gas enters valve body
Inner cavity after, and continuing open-top upper end has the valve deck of spring tension that could be vented, and similar exhaust mode direct part counteracts
The pressure that high pressure gas is discharged outside substantially reduces the capacity in the unit interval.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide novel straight knurling safety valve, packet
Valve body, spool, O-ring, valve seat, spring, adjusting nut, valve deck are included, the inner cavity lower end of valve body sets the inlet channel of taper, air inlet
Channel upper end, which covers, installs spool flexible, and after spool peripheral hardware O-ring in the valve seat of embedded upper end, the position of valve seat is in inner cavity
In, upper end sheathed spring, spring top insertion upper end adjusting nut interior blind hole in and offset, the valve of adjusting nut and upper end
Lid connection, valve deck excircle are evenly distributed with straight knurling, and the utility model adjusts bullet by selecting valve deck synchronous drive adjusting screw
Spring is sealed to control closing of the flexible spool to inlet channel using soft-type, and property of coincideing is high, and simple in structure, space is tight
It gathers, security performance is high, and capacity foot saves the energy, greatly improves the need satisfaction degree of user.
In order to achieve the above objectives, the technical solution of the utility model is：Novel straight knurling safety valve, including valve body, valve
Core, O-ring, valve seat, spring, adjusting nut, valve deck, the inner cavity lower end of the valve body set the inlet channel of taper, the air inlet
Channel upper end, which covers, installs spool flexible, after the spool peripheral hardware O-ring in the valve seat of embedded upper end, the position of the valve seat
In the lumen, the top of upper end sheathed spring, the spring is embedded in the interior blind hole of upper end adjusting nut and offsets, the adjusting
Nut and the valve deck of upper end connect, and 8 excircle of the valve deck is evenly distributed with straight knurling.
The internal chamber wall of the valve body sets several with the external exhaust outlet being connected to.
The beneficial effects of the utility model：The utility model adjusts bullet by selecting valve deck synchronous drive adjusting screw
Spring is sealed to control closing of the flexible spool to inlet channel using soft-type, and property of coincideing is high, and simple in structure, space is tight
It gathers, security performance is high, and capacity foot saves the energy, greatly improves the need satisfaction degree of user.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：Valve body 1, exhaust outlet 102, spool 2, O-ring 3, valve seat 4, inner cavity 5, spring 6, is adjusted inlet channel 101
Nut 7, valve deck 8, straight knurling 801.
Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Figure 1, novel straight knurling safety valve, including valve body 1, spool 2, O-ring 3, valve seat 4, spring 6, adjusting
Nut 7, valve deck 8,5 lower end of inner cavity of the valve body 1 set the inlet channel 101 of taper, 101 upper end of inlet channel covering peace
Spool 2 flexible is filled, material cost is substantially reduced, is embedded in the valve seat 4 of upper end after 2 peripheral hardware O-ring 3 of the spool, eliminates valve
The brinelling of core 2 and valve seat 4, in inner cavity 5, upper end sheathed spring 6, the top of the spring 6 is embedding for the position of the valve seat 4
Enter in the interior blind hole of upper end adjusting nut 7 and offset, the adjusting nut 7 is connect with the valve deck 8 of upper end, 8 outer circle of the valve deck
Zhou Junbu straight knurling 801, the utility model are soft to control by selecting valve deck synchronous drive adjusting screw come adjustment spring
Property closing of the spool to inlet channel, sealed using soft-type, property of coincideing is high, simple in structure, spaces compact, and security performance is high,
Capacity foot, saves the energy, greatly improves the need satisfaction degree of user.
5 wall of inner cavity of the valve body 1 sets several with the external exhaust outlet 102 being connected to, and capacity foot is conducive under the state of emergency
Quick air-discharge, after high pressure gas overcomes the pressure of adjustment spring 7 to wash spool open upwards, high pressure gas enters in inner cavity 5 directly
It is discharged to the outside from the exhaust outlet 102 on 5 periphery of inner cavity, quickly reduces the air pressure in high-pressure bottle.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.
The technical staff of the industry is also aware that the utility model is not limited by above-mentioned case study on implementation, above-mentioned case study on implementation and specification
Described in only illustrate the principles of the present invention, do not depart from the utility model design scope under the premise of, the utility model
It will also have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.This practicality is new
Type is claimed range and is defined by the appending claims and its equivalent thereof.
