Abstract
A kind of valve body safety cap of manual adjusting, including valve deck, valve deck connects shift fork by pin connecting valve seat, spool fixed sleeves, top is connected and fixed plate, for shift fork by pin connection valve deck, handle connects valve deck by pin block, when pressure increase or spool be adhered when, open pin, handle is pulled, drives valve deck to lift by handle, spool is promoted to move up.1) there is the case where not take-off, periodically to carry out experiment of releasing to safety valve in the handle safe valve core adhesion in order to prevent being fixed on bonnet.It can also be with emergency decompression.2) linear motion of rod set is switched to the rotary motion of shift fork by pin connection between bonnet and shift fork, pin and shift fork, and shift fork rotation drives output shaft rotation, to realize the control to valve.
Description
Technical field
The invention belongs to safety valve fields, and in particular to a kind of valve body safety cap of manual adjusting.
Background technique
Safety valve belongs to automatic valve class, is mainly used for boiler, on pressure vessels and pipes.Spring safety valve is by spring
Elastic pressure and the sealing elements such as the valve of valve or plunger are latched, the high pressure that is generated after when the pressure anomaly of pressure vessel general
Overcome the spring pressure of safety valve, so blocking device is opened, forms a pressure release passage, high voltage relief is fallen.But mesh
The pressure release of preceding major part valve is dangerous, and without manual pressure control, certain damage is caused to valve body.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of valve body of manual adjusting peaces
Full cap can prevent spool adhesion, while can emergency decompression.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of valve body safety cap of manual adjusting, including valve deck, valve deck are connected by pin connecting valve seat, spool fixed sleeves
Shift fork is connect, top is connected and fixed plate, and shift fork connects valve deck by pin block by pin connection valve deck, handle.
The spool fixed sleeves are equipped with adjusting nut.
The beneficial effects of the present invention are:
1) there is the case where not take-off in the handle safe valve core adhesion in order to prevent being fixed on bonnet, be periodically to safety
Valve carries out experiment of releasing.It can also be with emergency decompression.
2) linear motion of rod set is switched to the rotary motion of shift fork by pin connection between bonnet and shift fork, pin and shift fork, is dialled
Fork rotation drives output shaft rotation, to realize the control to valve.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of valve body safety cap of manual adjusting, including valve deck 1, valve deck 1 pass through 8 connection valve of pin
Seat, spool fixed sleeves 5 connect shift fork 4, and top is connected and fixed plate 2, and shift fork 4 connects valve deck 1 by pin 3, and handle 9 passes through pin block
7 connection valve decks 1.
The spool fixed sleeves 5 are equipped with adjusting nut 6.
The working principle of the invention:
When pressure increase or spool be adhered when, open pin, pull handle, by handle drive valve deck lift, promote valve
Core moves up.
