Abstract
The utility model discloses a novel pressure-relieving valve which comprises a valve body (1). An air inlet (2) is arranged in the upper end of the valve body (1). A guiding rod (3) is further arranged on the valve body (1) in the axial direction. A spring (4) is arranged on the guiding rod (3) in a sleeved mode. The upper end of the spring (4) is connected with a spring upper seat (5) and the lower end of the spring (4) is connected with a spring bottom seat (6). A sealing gasket (8) is connected with the upper portion of the spring upper seat (5). The spring bottom seat (6) is fixedly connected with one end of an adjustable screw rod (7). The other end of the adjustable screw rod (7) penetrates out of the valve body (1). The novel pressure-relieving valve is simple in structure, easy to disassemble, assemble and maintain, and capable of adjusting air pressure in a high pressure positive blower and other equipment conveniently and fast.
Description
Technical field
The utility model relates to a kind of pressure release valve, particularly a kind of novel pressure release valve.
Background technique
At present in the equipment such as high pressure positive blower; usually can use pressure release valve that the pressure of high pressure positive blower is regulated; high pressure positive blower is installed in fan outlet with pressure release valve or above the inlet pipe, the pressure that pressure release valve will surpass discharges by distinguished and admirable, thereby plays the effect of protection high pressure positive blower.But existing pressure release valve has fixing specification usually, can't satisfy the requirement of air pressure in the equipment such as regulating high pressure positive blower, and complex structure often, and inconvenient dismounting is safeguarded.
The model utility content
The purpose of this utility model is to provide a kind of novel pressure release valve, and it is simple in structure, is easy to dismounting and safeguards, and can realize conveniently adjusting to air pressure in the equipment such as high pressure positive blower by this novel pressure release valve, thereby overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of novel pressure release valve, comprise valve body, described valve body upper end is provided with intake grill, described valve body also is provided with a guide rod vertically, be arranged with a spring on the described guide rod, described spring upper and lower end respectively with a spring seat of honour with is connected spring pedestal and is connected, top, the described spring seat of honour is connected with gasket seal, but described spring pedestal is fixedly connected with an adjusting screw rod one end, but the described adjusting screw rod the other end passes in valve body.
As one of preferred embodiment, described valve body adopts conical structure.
As one of preferred embodiment, be distributed with outside thread on the outer wall on described valve body top.
As one of preferred embodiment, described valve body, guide rod, spring, the spring seat of honour, spring pedestal and the coaxial setting of gasket seal.
As one of preferred embodiment, described gasket seal adopts rubber sheet gasketing.
Compared with prior art, the utility model has following advantage at least:
(1) but only by adjusting adjusting screw rod and the relative position of valve body and the length of pressure release valve contained spring, can realize the adjusting to equipment internal air pressures such as high pressure positive blowers, convenient and swift.
(2) pressure release valve can be opened automatically when the air pressure in the equipment such as high pressure positive blower reaches the pressure release valve setting value; make outside air enter the inner chamber of the equipment such as high pressure positive blower by pressure release valve; thereby reach the temperature that reduces the equipment such as high pressure positive blower and the effect of protecting high pressure positive blower, make the working life of high pressure positive blower elongated.
(3) prevent that air pressure in the equipment such as high pressure positive blower from crossing minuent or working time is long, and then stop high pressure positive blower because of overload and overheated and impaired.
Description of drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and a preferred embodiment the technical solution of the utility model is further described.
Consult Fig. 1, the present embodiment system is about a kind of pressure release valve, it comprises valve body 1, described valve body upper end is provided with intake grill 2, and, also be provided with vertically a guide rod 3 in the described valve body 1, be arranged with a spring 4 on the described guide rod 3, described spring 4 upper and lower ends respectively with a spring seat of honour 5 with is connected spring pedestal 6 and is connected, 5 tops, the described spring seat of honour are connected with gasket seal 8 (such as rubber sheet gasketing etc.), but described spring pedestal 6 is fixedly connected with an adjusting screw rod 7 one ends, but described adjusting screw rod 7 the other ends pass in valve body.
Further, described valve body 1 can adopt conical structure.
Be distributed with outside thread 9 on described valve body 1 external wall of upper portion.
Described valve body 1, guide rod 3, spring 4, the spring seat of honour 5, spring pedestal 6 and gasket seal 8 coaxial settings.
So that this pressure release valve is applied as example in the equipment such as vacuum packager that are comprised of high pressure positive blower etc., it can reach following good effect at least:
(1) controls the degree of vacuum of processed product internal compression air by the length of regulating the pressure release valve contained spring.
(2) pressure release valve can be opened automatically when processed product internal compression air reaches the pressure release valve setting value; thereby make outside air reduce the temperature of high pressure positive blower and the effect of protection blower fan by the inside die cavity that pressure release valve enters high pressure positive blower, make the working life of high pressure positive blower elongated.
Too high or the overlong time of internal vacuum makes the high pressure positive blower overload and overheatedly causes mechanical damage when (3) preventing processed product.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
