Its simple structure, convenient to use guarantee the security of system, and the maintenance measure of being convenient for need not to change repeatedly blasting needle, material saving.
Description
Technical field
The utility model belongs to Decompression valves field, particularly a kind of Decompression valves of pin type.
Background technique
Decompression valves is the protective gear of pressurized container, pipeline or some other airtight bearing device; mainly contain rupture disk and safety valve at present; system pressure always exceedes material yield point in fluctuation under normal circumstances; thus can cause the explosion in advance of rupture disk, rupture disk temperature influence is comparatively large, in the industrial production because temperature range is larger; superpressure scope is also larger; this just causes rupture disk that explosion, the also likely delayed explosion of rupture disk in advance not only can occur, thus there is great potential safety hazard.Rupture disk very easily produces fragment in explosion moment in addition.And conventional safety valve is in order to can normally use, annual all need verification once, this for the input adding its manpower and materials applying unit, and needs dead time longer, lose time more, have the product of explosion needle-like Decompression valves at present, but it needs to use explosion pin, reaches certain pressure, pin is destroyed, realize pressure release, so just need longer-term storage explosion pin, bring certain burden to maintenance.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of pin type Decompression valves, and its structure is simple, easy to use, ensures security of system, is convenient to maintenance conditions, without the need to repeatedly changing explosion pin, saves material.
The technical scheme in the invention for solving the technical problem is: lower valve body has a left side, right port and upper port, left, right port has a left side respectively, right flange, left port puts interface for unloading, right port is feed liquor interface, a left side is had in lower valve body, the internal channel that right port communicates, on upper port, upper valve body is fixed in removable sealing, upper valve body fixes end cap by strut, upper valve body is gone back fixing spring room, first connecting rod is fixed slidably by spring housing, first connecting rod in spring housing and have spring between spring housing's inwall, first connecting rod outside spring housing simultaneously and second connecting rod, one end of third connecting rod is hinged, second connecting rod, the other end of third connecting rod respectively with end cap, piston rod is hinged, the other end of piston rod is fixed through described upper valve body and piston slidably, the left side of piston top in described lower valve body, on the internal channel of right port.
The utility model structure is simple, easy to use, ensures security of system, is convenient to maintenance conditions, without the need to repeatedly changing explosion pin, saves material.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, lower valve body there is a left side, right port 18, 13 and upper port 11, left, right port 18, 13 have a left side respectively, right flange 19, 12, left port 18 puts interface for unloading, right port 13 is feed liquor interface, a left side is had in lower valve body, the internal channel 17 that right port communicates, on upper port 11, upper valve body 9 is fixed in removable sealing, upper valve body 9 fixes end cap 4 by strut 5, upper valve body 9 is gone back fixing spring room 1, spring housing 1 fixes first connecting rod 3 slidably, first connecting rod 3 in spring housing 1 and have spring 2 between spring housing 1 inwall, first connecting rod 3 outside spring housing 1 simultaneously with second connecting rod 6, one end of third connecting rod 7 is hinged, second connecting rod 6, the other end of third connecting rod 7 respectively with end cap 4, piston rod 8 is hinged, the other end of piston rod 8 is fixed through described upper valve body 9 and piston 16 slidably, piston 16 withstands on the left side in described lower valve body, on the internal channel 17 of right port.
The slide opening two ends inwall of the described upper valve body 9 coordinated with piston rod 8 is fixed with seal ring 10.
Guide pin bushing 14 is fixed at internal channel 17 place of the described lower valve body coordinated with piston 16, and described piston 16 is slidably matched with guide pin bushing 14.
Fixed piston seal ring 15 on the outer wall of described piston 16, piston packing 15 and described guide pin bushing 14 are slidably matched.
When the pressure of right port reaches certain value, piston 16 is upwards opened, and the pressure of right port 13 starts to unload to be put.Piston rod 8 promotes third connecting rod 7 and second connecting rod 6 articulating point to left movement, and finally realize first connecting rod 3 straight line motion left, spring 2 is extruded energy storage.
After earth pressure release falls, spring 2 resets, and promotes first connecting rod 3 and moves right, thus the interface point promoting second connecting rod 6 and third connecting rod 7 moves right, final promotion piston rod 8 moves downward, and piston 16 closes the internal channel 17 of left and right port 18,13, stops unloading putting.
