Abstract

The utility model relates to a diaphragm type pressure gauge, which relates to a pressure gauge capable of measuring the pressure of a gas-liquid flow pipe and is used for solving the problems of easy gas leakage, easy liquid leakage, inaccurate measuring pressure, unchangeable damaged parts, easy corrosion, etc. in the prior art. The utility model is mainly composed of a gauge head and a connecting base, wherein the gauge head and the connecting base are made of plastic cement materials with corrosion resistance performance in an integral forming so that reliability, the situation of no oil leakage, and durability can be improved. The gauge head is formed by the method that a ring frame is screwed with a head body in a screwed connection mode; thereby, parts in the gauge head is easy to change when damaged. The utility model is mainly used for measuring the pressure of the gas-liquid flow pipe.

Description

Diaphragm pressure gage

Technical field

The utility model is meant a kind of tensimeter of measuring the gas-liquid flow-line pressure especially about a kind of tensimeter.

Background technology

The structural form of general gas or fluid pressure table is very diversified, but how to develop a kind ofly do not have leakage of oil, do not change former pressure through collision, easy one of at present important just problem of renewal part and free from corrosion gas-liquid tensimeter.

As shown in Figure 1, general compressive force table is mainly by a gauge outfit 11 a connecting seat 12 that is spirally connected, and is to avoid metal tensimeter to be exposed in the gas-liquid environment of tool chemical corrosion, and regular meeting is a sheathed belled body 13 outside this tensimeter.

But if cooperate the actual situation of using, being not difficult to find wherein still to have need improved immediately defective:

One, because existing tensimeter is to be spirally connected mutually with a connecting seat 12 by a gauge outfit 11 to form, after using for a long time, the situation that its place of being spirally connected 14 has gas leakage, liquid produces.

They are two years old, because existing tensimeter is by pressure regulation part 15 the pressure adjustment in the tensimeter to be made zero, and manometric gauge outfit 11 is rotatable with Connection Block 12 between the two, so when work and touch this tensimeter, 11 of this gauge outfits can be rotated on this Connection Block 12, and the pressure in the change tensimeter causes the inaccurate of gaging pressure.

Its three because existing manometric gauge outfit 11 is to be formed in a body 112 by a ring frame 111 rivet clasps, when manometric damage parts, then can't change.

Its four, though the outer sheathed belled body 13 of existing tensimeter still has the existence of joint close, so this tensimeter is also perishable between this belled body 13 and the tensimeter.

Summary of the invention

The purpose of this utility model is to provide a kind of diaphragm pressure gage, in order to solve easy gas leakage of prior art and leakage, gaging pressure is inaccurate, damage parts can't be changed, problem such as perishable.The purpose of this utility model be achieved in that its with manometric gauge outfit and Connection Block to be made into integration, so do not have seam crossing between manometric gauge outfit and the Connection Block, tensimeter is oil-proof thus, and can not change manometric former pressure through collision; Connection Block is provided with pressure regulation part and junction surface, and the junction surface is connected gas-liquid stream pipe or other pipe devices; It is made tensimeter Connection Block and gauge outfit with corrosion proof plastic cement material, tensimeter is not perishable thus; This manometric gauge outfit is to be established with the mutual spiral shell of the mode of being spirally connected with the ring frame by a body to form, and thus, the part in the gauge outfit is changed easily.

Compared with prior art, the utility model structural design possesses following advantage:

One, after the utility model makes zero the pressure adjustment in this tensimeter by the pressure regulation part on this Connection Block, can be connected on gas-liquid stream pipe or other containers by the junction surface, touch this tensimeter thus at work, this tensimeter is formed in one, so the pressure in this tensimeter then can not change, and improve fiduciary level.

Its two, manometric gauge outfit of the utility model and Connection Block are being made into integration, so do not have seam crossing between manometric gauge outfit and the Connection Block, tensimeter can leakage of oil thus.

Its three, in measuring, this tensimeter can be exposed in the gas-liquid environment of tool chemical corrosion, the utility model tensimeter is to make etch-proof structure by corrosion proof plastic cement material on the whole, so can improve the tensimeter durability.

Its four, the utility model gauge outfit is to be bolted in a body in the mode of being spirally connected and to be formed by the ring frame, thus, this body can be dismantled mutually with the ring frame and combine, and is easy to replacing after making the damage parts in the gauge outfit.

Embodiment

At first please cooperate and consult Fig. 2, Fig. 3, shown in Figure 4, a kind of diaphragm pressure gage provided by the utility model, mainly constituted with a connecting seat 3 by a gauge outfit 2, wherein: this gauge outfit 2, make with corrosion proof plastic cement material, have a body 21 and a ring frame 22, this ring frame 22 is bolted in a body 21, and is provided with the required element of gaging pressure 23 in the body 21 (as Baden's pipe, gear set, inscription plate, pointer ... or the like); This Connection Block 3 is made with corrosion proof plastic cement material, and one-body molded with gauge outfit 2, which is provided with pressure regulation part 31 and junction surface 32, and this pressure regulation part 31 is in order to adjusting the usefulness that manometric pointer makes zero, and junction surface 32 is in order to be connected gas-liquid stream pipe or other containers.The above is the mutual relationship position of each main member of the utility model embodiment.

In sum, structural design of the present utility model tensimeter is had improve fiduciary level, can not leakage of oil, improve advantages such as durability and renewal part be easy.
