Abstract
The utility model discloses a non-removable liquefied petroleum gas angle valve in the field of valves. The non-removable liquefied petroleum gas angle valve comprises a valve core which is arranged in a valve body, wherein the valve core is movably connected with the bottom of a valve rod through a piston; a thread is formed in the middle of the valve rod; the valve rod is connected with the valve body through threads; a pressing cap is arranged at the top of the valve body; the top of the valve rod penetrates through the pressing cap; the top of the valve rod is processed into a threaded column; a hand wheel sleeves the threaded column and is fixed to the threaded column through the cooperation of a nut and a gasket. The pressing cap is arranged at the top of the valve body, and the hand wheel is fixed to the valve rod through the cooperation of the nut and the gasket, so that the pressing cap is required to be removed firstly to remove the valve rod; manual removal of the pressing cap is relatively complicated, and special equipment is needed, so that the safety of the valve is improved, and potential safety hazards are eliminated. The non-removable liquefied petroleum gas angle valve can be used in a liquefied petroleum gas steel cylinder.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of liquid gas angle valve.
Background technique
The civilian oil liquefied gas steel cylinder of China is mostly to offer the common people by liquefied petroleum gas gas company as the packing material of gas to use at present, and there is the gas station of oneself in Ge great liquefied petroleum gas company.Along with scientific and technical progress, scientific & technical corporation has developed the electronics from L. P. G air drain Guan Jin factory to packing, usertracking, has improved the managerial skills at gas station and has worked hard in glove with client's information.But some small inflatable points, for activating business, are bribed inflation personnel, take angle valve valve body apart, inflate after punching its electronic control part with drill bit, cause very large potential safety hazard.A kind of dimethyl ether resistant cylinder valve is disclosed in prior art, its publication number is CN202812217U, comprise the spool and the valve rod that are arranged in valve body, threaded stem is connected in valve body, underpart and the spool of valve rod link together, on spool, offer gasket groove, in gasket groove, be set with seal ring, on the lower end surface of spool, offer spacer groove, in spacer groove, be fixedly installed the sealing gasket that cyclinder gas import is closed, between spool and valve body, in cavity, be injected with lubricating grease, its deficiency is, this valve can artificially be removed valve rod easily, thereby reduce the Security of valve, there is very large potential safety hazard.
Model utility content
The purpose of this utility model is to provide a kind of non-removable liquefied petroleum gas angle valve, improves the dismounting difficulty of valve rod, improves the Security of valve, eliminates safe hidden trouble.
The purpose of this utility model is achieved in that a kind of non-removable liquefied petroleum gas angle valve, comprise the spool being arranged in valve body, described spool is movably connected through piston and stem bottom, described valve rod middle part is processed with screw thread, described valve rod and valve body screw thread link together, described valve body top is provided with pressure cap, described valve rod top is through pressure cap setting, screw column is processed at described valve rod top, in described screw column, be set with handwheel, described handwheel is fixed together through nut Passscheiben and screw column.
Compared with prior art, the beneficial effects of the utility model are, the utility model arranges pressure cap by the top at valve body, and handwheel is fixed together by nut Passscheiben and valve rod, the dismounting of valve rod must first be removed pressure cap in advance, and the dismounting of pressure cap is comparatively complicated, and difficulty is higher, this has just improved the Security of valve, thereby has eliminated potential safety hazard.The utility model can be used in cylinder for liquefied gas.
In order to strengthen the reliability of assembling between pressure cap and valve body, increase and remove difficulty, described pressure cap periphery is processed with crimping, and described pressure cap is riveted together by crimping and valve body top; In the middle of described pressure cap and valve body, be provided with pad.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 valve body, 2 spools, 3 pistons, 4 valve rods, 5 pressure caps, 5a crimping, 6 handwheels, 7 packing rings, 8 nuts, 9 pads.
Embodiment
The non-removable liquefied petroleum gas angle valve of one as shown in Figure 1, comprise the spool 2 being arranged in valve body 1, spool 2 is movably connected through piston 3 and valve rod 4 bottoms, valve rod 4 middle parts are processed with screw thread, valve rod 4 is threaded togather with valve body 1, valve body 1 top is provided with pressure cap 5, pressure cap 5 peripheries are processed with crimping 5a, pressure cap 5 is riveted together by crimping 5a and valve body 1 top, pressure cap 5 and the middle pad 9 that is provided with of valve body 1, valve rod 4 tops arrange through pressure cap 5, screw column is processed at valve rod 4 tops, in screw column, be set with handwheel 6, handwheel 6 is fixed together with screw column through nut 8 Passscheibens 7.
The utility model is by arranging pressure cap 5 at the top of valve body 1, and handwheel 6 is fixed together with valve rod 4 by nut 8 Passscheibens 7, the dismounting of valve rod 4 must first be removed pressure cap 5 in advance, and the dismounting of pressure cap 5 is comparatively complicated, and difficulty is higher, this has just improved the Security of valve, thereby has eliminated potential safety hazard, the structure of crimping 5a makes pressure cap 5 more reliable with being connected of valve body 1, and dismounting difficulty is higher.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in protection domain of the present utility model.
