Abstract
The utility model discloses a high-sealing air compressor safety valve which comprises a protective cover, nuts, an upper supporting pad, a spring, a valve shaft, a lower supporting pad, a valve cover, a valve clack, a valve seat and a valve body, wherein the upper end of the spring is connected with the upper supporting pad, the lower end of the spring is connected with the lower supporting pad, an upper supporting frame is fixedly connected with the protective cover through the nuts, the lower end of the valve shaft penetrates through the spring, and is connected with the valve clack and the valve seat in sequence, an elastic groove is formed in the side wall of the valve clack, and an arc-shaped groove is formed in the bottom of the valve clack. Due to the fact that the elastic groove is formed in the side wall of the valve clack, an additional sealing force is added to the high-sealing air compressor safety valve, and thus the high-sealing air compressor safety valve is enabled to obviously have good sealing performance in high temperature. Due to the fact that the arc-shaped groove is formed in the bottom of the valve clack, sealing surface elasticity loss caused by sudden close movement can be effectively avoided when the high-sealing air compressor safety valve resets.
Description
Technical field
The utility model relates to a kind of safety valve, particularly relates to a kind of high sealing safety valve of air compressor.
Background technique
Safety valve not only requires to open in certain pressure rise zone, also requires simultaneously to close when certain Pressure Drop.This has proposed opposite requirement to safety valve structure.Safety valve keep the condition of sealing than the shutoff device complexity many because under latter event, sealing surface does not bear very large power.And the difference between the pressure of the pressure in safety valve when sealing during with unlatching is limited by specified standard, and numerical value is not too large, so the closing means of safety valve should in the situation that spring force is very little over air pressure, can keep the almost state of balance.Therefore, the leakage of safety valve is one of the most scabrous problem.In fact, absolute being tightly connected is to be difficult to realize.The principal element that affects the safety valve sealing is as follows: (l) seal style and enclosed construction; The partial twist that causes when (2) assembling valve seat, flap; (3) width of seal ring, material and surface roughness; (4) the closing means external and internal pressure is poor; (5) again recover the characteristic of seal process.
Summary of the invention
The purpose of this utility model be a kind of good sealing effect to be provided in order addressing the above problem, be difficult for to leak, high sealing safety valve of air compressor simple in structure.
The utility model is achieved through the following technical solutions:
A kind of high sealing safety valve of air compressor; comprise safety cover, nut, on prop up pad, spring, valve shaft, prop up pad, valve bonnet, flap, valve seat and valve body down; the upper end of described spring is connected with described upper pad; the lower end of described spring is connected with described lower pad; described upper bracket is fixedly connected with described safety cover by nut; the lower end of described valve shaft is passed spring and is connected with valve seat with flap successively, and the sidewall of described flap is provided with elastic groove, and the bottom of described flap is provided with circular groove.
Make safety valve increase an additional seal power by elastic groove is set on the sidewall of described flap, thereby make safety valve at high temperature obviously have good sealing.The action of closing suddenly again during safety valve blowback, thereby a larger cushion effect is arranged, concerning Elastic valve clack, sealing surface has a very large distortion that pops up, for the sealing surface loss of elasticity that prevents from causing thus, so be provided with circular groove in the bottom of flap.
As preferably, the lower end of described valve shaft and valve chamber be movable coordinate and both between be provided with the O RunddichtringO.
Further, described safety valve also comprises adjusting screw, and described valve shaft front end is fixedly connected with by adjusting screw with described upper pad.
The beneficial effects of the utility model are:
Make safety valve increase an additional seal power by elastic groove is set on the sidewall of described flap, thereby make safety valve at high temperature obviously have good sealing.By the bottom at described flap, circular groove is set, the sealing surface loss of elasticity that the action of closing suddenly again in the time of effectively preventing safety valve blowback causes.

Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
As shown in Figure 1; a kind of high sealing safety valve of air compressor of the utility model; comprise safety cover 1, nut 2, upper pad 4, spring 5, valve shaft 6, lower pad 7, valve bonnet 8, flap 9, valve seat 10 and valve body 11 of propping up; the upper end of described spring 5 is connected with described upper pad 4; the lower end of described spring 5 is connected with described lower pad 7; described upper bracket 4 is fixedly connected with described safety cover 1 by nut 2; the lower end of described valve shaft 6 is passed spring 5 and is connected with valve seat with flap 9 successively and is connected; the sidewall of flap 9 is provided with elastic groove 12, and the bottom of flap 9 is provided with circular groove 13.
Make safety valve increase an additional seal power by elastic groove 12 is set on the sidewall of described flap 9, thereby make safety valve at high temperature obviously have good sealing.The action of closing suddenly again during safety valve blowback, thereby a larger cushion effect is arranged, concerning Elastic valve clack 9, sealing surface has a very large distortion that pops up, for the sealing surface loss of elasticity that prevents from causing thus, so be provided with circular groove 13 in the bottom of flap 9.
The lower end of valve shaft 6 and valve body 11 chambers are movable coordinate and both between be provided with O RunddichtringO 14.Described safety valve also comprises adjusting screw 3, and valve shaft 6 front ends are fixedly connected with by adjusting screw 3 with upper pad 4.
