Abstract
The invention discloses a valve with an integrated valve rod and limit bolts. The valve comprises a valve body and a valve rod, wherein limit grooves are formed in the middle part of the valve rod; limit bolt holes are formed in the valve body; limit bolts are arranged in the limit bolt holes; a sealing part is arranged at the lower end of the valve rod; O-shaped seal rings are arranged at the lower middle part of the valve rod and are located between the limit grooves and the sealing part; a first channel is arranged at the lower part of the valve body; a second channel is arranged on the left side of the valve body; the first channel and the second channel are vertically the same; an upward bulge is arranged at the upper end of the first channel; the lower end of the sealing part is propped against the bulge; and the sealing part and the O-shaped seal rings are integrally assembled on the valve rod. According to the valve, the sealing part and the O-shaped seal rings are integrally assembled on the valve rod, so that the assembly performance of the valve is improved; and furthermore, the sealing problem caused by multiple sealing is solved.
Description
Technical field
The present invention relates to extinguisher device field, specifically a kind of valve rod unitary tape stop screw type valve.
Background technique
Existing fire extinguisher screw type valve mechanism design is unreasonable, general employing spool combination, valve-rod combination, the split type assembling of gland nut, the deficiency of these assembling forms is that needs are multiple-sealed, assembly process is cumbersome, the assembly performance of product is not high, and sealability is not good, causes the maximum opening travel of valve to be restricted, fire extinguisher gas output reduces, and is delayed flame extinction time.
Summary of the invention
The object of this invention is to provide valve rod unitary tape stop screw type valve.
It is unreasonable that the present invention will solve the design of existing fire extinguisher screw type valve mechanism, and need multiple-sealed, assembly process bothers, and assembly performance is not good, the problem that the maximum opening travel of valve is restricted.
Technological scheme of the present invention is: a kind of valve rod unitary tape stop screw type valve, comprise valve body and valve rod, restraining groove is provided with in the middle part of described valve rod, described valve body is provided with stop screw hole, stop screw is provided with stop screw in hole, described valve rod lower end is provided with Sealing, described valve rod middle and lower part is provided with O RunddichtringO, and described O RunddichtringO is located between described restraining groove and Sealing, described valve body lower portion is provided with first passage, left side is provided with second channel, described first passage is vertical with second channel identical, the upper end of described first passage is provided with projection upwards, the lower end of described Sealing withstands in described projection, described Sealing, on the integrated assembling of O RunddichtringO and described valve rod.
Preferably, described valve rod upper end is provided with working head, is fixed, fixed between described valve rod and described valve body by thread engagement mode by screw and described valve rod.
Preferably, the outside of described valve body lower end is provided with outside thread, the left part of described valve body and the outside being positioned at second channel is provided with outside thread.
Preferably, the right side of described valve body is provided with pressure-relieving device.
Preferably, described stop screw is two, radially symmetrical.
Preferably, described O RunddichtringO is at least two.
Beneficial effect of the present invention is: the present invention adopts that Sealing, O RunddichtringO are integrated to be assemblied on valve rod, easy to assembly, improve the assembly performance of product, solve multiple-sealed brought sealing problem further, valve rod is undertaken spacing by stop screw, thus ensure that the maximum opening travel of valve.
